As shown in FIG. 1, the chemical weighing system 1 according to the embodiment of the present invention includes a chemical weighing device 10 for weighing chemicals and a chemical packaging device 20 for packaging chemicals. A user such as a doctor or a pharmacist places a drug on a drug sheet 30 (an example of a drug mounting member) and weighs the drug with the drug weighing device 10. After that, the user moves the medicine sheet 30 on which the weighed medicine is placed to the medicine packaging device 20, and puts the medicine into the medicine packaging device 20. As a result, the chemicals are packaged one by one in the chemical packaging device 20.

The chemical packaging device 20 may have each function of the chemical weighing device 10, and in this case, the chemical packaging device 20 corresponds to the chemical weighing system according to the present invention. Further, the conventional configuration (see, for example, Patent Document 1) may be adopted for the points that the chemical weighing device 10 is not described in the present embodiment.

[Chemical weighing device 10]
First, a schematic configuration of the chemical weighing device 10 will be described with reference to FIGS. 1 and 2.

The chemical weighing device 10 includes a control unit 11, a balance unit 12, a touch panel 13, an RFID reader / writer 14, a data storage unit 15, a USB port 16, a barcode reader 17, a printer 18, and the like. In particular, at least the control unit 11, the balance unit 12, and the touch panel 13 are integrally provided on the main body of the chemical weighing device 10. The drug weighing device 10 can be used for weighing various dosage forms of drugs such as powders, liquids, tablets, and heat agents (predetermined amounts of powders or tablets packaged).

The control unit 11 is a computer including a CPU, ROM, RAM (EEPROM, etc.) and the like, and controls the drug weighing device 10 in an integrated manner. The CPU is a processor that executes various arithmetic processes according to various programs. The ROM is a non-volatile memory in which a program such as a BIOS executed by the CPU is stored in advance. The RAM is a volatile memory or a non-volatile memory used for the development of various programs by the CPU and the temporary storage of data in various arithmetic processes.

The balance unit 12 is an example of a weighing means for weighing chemicals placed on a stainless steel balance table 19. Specifically, the balance unit 12 is a balance unit that is also used in a conventionally known electronic balance provided with a balance circuit, a force coil, a current / voltage conversion circuit, an A / D conversion circuit, and the like. The weight of the chemicals weighed by the balance unit 12 is input to the control unit 11 as digital data. A windshield cover (not shown) for preventing the powder on the balance table 19 from being scattered by the wind can be attached to and detached from the chemical weighing device 10.

When the user weighs the medicine with the medicine weighing device 10, the user puts the medicine sheet 30 on the balance table 19 and then puts the medicine on the medicine sheet 30. Further, the drug sheet 30 is provided with an RFID tag 31 as a recording medium for reading and writing various information. Here, the RFID tag 31 is provided at a position where data can be read and written by the RFID reader / writer 14 when the drug sheet 30 is placed on the balance table 19. The balance unit 12 uses a value obtained by subtracting the weights of the preset drug sheet 30 and the RFID tag 31 as the weighing value of the drug.

The touch panel 13 detects an operation of a display unit such as a liquid crystal panel or an organic EL panel that displays various screens and various information according to a control instruction from the control unit 11, and an operation key displayed on the display unit. It is provided with a detection unit for inputting a detection signal to the control unit 11. That is, the touch panel 13 also serves as a display means and an input means in the chemical weighing device 10. Specifically, the control unit 11 causes the touch panel 13 to display the weighed value weighed by the balance unit 12 (see FIG. 7).

The RFID reader / writer 14 records information on an RFID tag or RFID label using RFID (Radio Frequency Identification) wireless communication technology, or reads information from the RFID tag or RFID label. The RFID reader / writer 14 is provided adjacent to the balance table 19 in order to read / write information to / from the RFID tag 31 when the drug sheet 30 is placed on the balance table 19. Used. Of course, the RFID reader / writer 14 may be built in the drug weighing device 10. Further, although FIG. 2 shows an example in which the RFID reader / writer 14 is arranged on the left side of the balance table 19, it may be configured to be arranged behind the balance table 19.

When the balance table 19 is made of resin or the like and does not block RFID wireless communication, the RFID reader / writer 14 is provided in the lower layer of the balance table 19, and the RFID tag 31 is the drug sheet 30. A configuration provided on the bottom surface of the device is also conceivable. As a result, when the drug sheet 30 is placed on the balance table 19, information can be read and written by the RFID reader / writer 14 to the RFID tag 31 regardless of the orientation of the drug sheet 30 or the like.

The data storage unit 15 stores various data such as a control program such as a drug weighing program executed by the control unit 11, a drug master (corresponding to drug information), and a generic drug master (corresponding to generic drug information). It is a USB memory and can be attached to and detached from the drug weighing device 10. Specifically, the data storage unit 15 is attached to and detached from the attachment portion of the USB port 16 exposed by removing the attachment / detachment cover (not shown) provided on the back surface of the chemical weighing device 10. Here, the removable cover (not shown) can be opened and closed without disassembling the control unit 11, the balance unit 12, the touch panel 13, and the like of the chemical weighing device 10. Therefore, the data storage unit 15 can be attached to and detached from the chemical weighing device 10 without any problem in the measurement method. Therefore, by appropriately exchanging the data storage unit 15, various data such as the drug weighing program, the drug master, and the generic drug master can be easily updated. The data storage unit 15 is not limited to the USB memory, and may be, for example, another recording medium such as a flash memory, a memory card, or a disk. Here, the data storage unit 15 in which the drug weighing program is recorded corresponds to the recording medium according to the present invention.

The drug weighing program is software that causes a computer such as the control unit 11 to execute each processing step of the drug weighing process (see FIG. 5) described later. For example, the drug weighing program operates on an OS such as an android (registered trademark) mounted on the control unit 11. In addition, the drug weighing program audits whether the weighing value of the drug is within the range of the usual dose (appropriate amount to be taken daily or once) preset for each drug by the control unit 11. It also includes an audit program to perform. Therefore, the drug weighing device 10 can perform both weighing and auditing a normal dose of a drug by itself without using another information processing device such as a computer. Here, the control unit 11 when executing the audit process corresponds to the audit means.

The drug master includes drug code, drug name, JAN code (or RSS), drug bottle code, classification (dosage form: powder, tablet, liquid medicine, external medicine, etc.), specific gravity, drug type (ordinary drug, poisonous drug, etc.). Includes drugs, powerful drugs, anti-psychiatric drugs, therapeutic drugs, etc.), formulation changes, excipients, precautions, regular doses (corresponding to appropriate dose information), and information on prohibition of simultaneous administration. Here, the data storage unit 15 is an example of a drug information storage means.

Here, the JAN code (RSS) is information corresponding to the name of the contained medicine (an example of the contained medicine identification information) recorded in the medicine bottle (an example of the medicine container) supplied from the pharmaceutical manufacturer, and is in the medicine bottle. The JAN code is recorded (described) by a bar code. The medicine bottle code is information corresponding to the name of the medicine contained in the medicine bottle (an example of the medicine container) when the medicine in the medicine box supplied from the pharmaceutical manufacturer is subdivided into the medicine bottle (an example of the medicine container). The medicine bottle code is recorded on the medicine bottle by a bar code. The control unit 11 can know the name of the contained drug corresponding to each of the barcodes by referring to the drug master.

By the way, in the present embodiment, the drug name (prescription drug name, contained drug name, original drug name, etc.) is used as the drug identification information (prescription drug identification information, contained drug identification information, generic drug identification information, generic drug identification information). The case where a generic drug name) is used will be described as an example, but the present invention is not limited to this, and a drug code or the like may be used. For example, when the control unit 11 and the control unit 21 described later compare the types of chemicals, they compare the chemical names, compare the chemical codes, specify the chemical name indicated by the chemical code, and specify the chemical name. It is conceivable to adopt various methods such as comparing, specifying the drug code indicated by the drug name and comparing the drug code, or comparing any one or more of these in combination.

The usual dose is an appropriate amount to be taken once a day or once, which is predetermined for each drug. In addition, the simultaneous administration prohibition information is information regarding the medicines prohibited to be taken at the same time, which are predetermined for each of the medicines. The regular dose and the simultaneous administration prohibition information are used in an audit process executed by the control unit 11 according to the audit program. Specifically, the control unit 11 stores in the data storage unit 15 an audit of whether or not the weighing value weighed by the balance unit 12 is within the range of an appropriate amount preset for each drug. It is carried out based on the usual dose. Further, the control unit 11 audits the data storage unit 15 whether or not a plurality of drugs contained in the prescription information read by the barcode reader 17, which will be described later, are prohibited from being taken at the same time. This is performed based on the stored simultaneous administration prohibition information.

Then, when the weighed value is out of the range of the usual dose, or when there is a drug for which it is prohibited to be taken at the same time as the drug recorded in the prescription, the control unit 11 has the effect to that effect. It is conceivable to display a warning on the touch panel 13 or the like. The control unit 11 displays the warning by characters, images, voice, or light. As a result, it is possible to prevent the prescription of a drug in an amount exceeding the usual dose and the prescription of a plurality of drugs that cause a change in formulation or side effects when taken at the same time at the drug weighing stage in the drug weighing device 10. can.

In addition, the generic drug master includes the drug name, JAN code (or RSS), drug bottle code, classification (dosage form: powder, tablet, liquid drug, external drug, etc.), specific gravity, and drug type (ordinary) for the generic drug. Drugs, poisons, drugs, powerful drugs, anti-psychiatric drugs, therapeutic drugs, etc.), compounding changes, shaping drugs, precautions, regular doses (corresponding to appropriate amount information), simultaneous administration prohibition information, etc. are stored. Also when the generic drug is weighed by the drug weighing device 10, the audit process based on the normal dose or the simultaneous administration prohibition information by the control unit 11 is performed in the same manner as described above.

Further, in the generic drug master, a correspondence relationship between a plurality of generic drug names (an example of generic drug identification information) and a plurality of generic drug names (an example of generic drug identification information) is defined. Specifically, in the generic drug master, the name of the original drug and the name of the generic drug having the same efficacy are stored in association with each other. Further, in the generic drug master, the name of the original drug and the name of the generic drug are stored in association with the common name of the drug. Here, the data storage unit 15 is an example of a generic drug information storage means. By referring to the generic drug master, the control unit 11 can know the generic drug name corresponding to each of the barcodes. The drug master and the generic drug master are read out by the control unit 11 or edited by the control unit 11.

Here, FIG. 3 is a main block diagram schematically showing a part of the data structure of the drug master and the generic drug master. As shown in FIG. 3, in the drug master, drug codes A, B, and C and drug names AA, BB, and CC are stored in association with each other. On the other hand, the generic drug master includes generic drug codes A', A'', generic drug codes B', B'', generic drug names AA', AA'', and generic drug names B', BB''. Each is stored in association with each other. The generic drug codes A'and A ″ are associated with the drug code A, which is a generic drug corresponding to the generic drug codes A ′ and A ″. Similarly, the generic drug codes B ″ and B ″ are associated with the drug code B, which is a generic drug corresponding to the generic drug codes B ″ and B ″. As a result, the control unit 11 establishes a correspondence relationship between the drug code A and the generic drug code A', AA'', and a correspondence relationship between the drug code B and the generic drug code B', BB''. Each can be known. Note that FIG. 3 shows a state in which a generic drug for the drug code C is not registered.

The USB port 16 is a communication interface for communicating with a USB device according to a USB (Universal Serial Bus) communication standard. The USB port 16 has at least three connection units to which the data storage unit 15, the barcode reader 17, and the printer 18 are attached / detached. Further, the driving power of the barcode reader 17 and the printer 18 is supplied from the USB port 16. Of course, the chemical weighing device 10, the barcode reader 17, and the printer 18 may be individually connected to a commercial AC power supply.

The connection method between the barcode reader 17 and the printer 18 and the chemical weighing device 10 is not limited to USB, and may be, for example, LAN or IEEE. Further, the barcode reader 17 and the printer 18 may be communicably connected to the chemical weighing device 10 by wireless USB, wireless LAN, or the like. Further, the barcode reader 17 may be provided integrally with the chemical weighing device 10.

The barcode reader 17 reads information from a one-dimensional barcode such as a JAN code or RSS and a two-dimensional code such as a QR code (registered trademark).

In the drug weighing device 10, the control unit 11 uses the barcode reader 17 to obtain prescription information including one or a plurality of prescription drug names (an example of prescription drug identification information) recorded (described) in the prescription. It is read from a two-dimensional code such as a QR code (registered trademark) recorded (described) on the prescription. The two-dimensional code is a display type code having information in the horizontal direction and the vertical direction, and can code more information than a barcode having information only in the horizontal direction, and can reduce the printing area. It can also be made smaller. Here, the control unit 11 when executing the reading process corresponds to the prescription information reading means. The prescription information includes prescription delivery date, patient ID, patient name, patient birth date, dosage form information (internal use, external use, etc.), drug information (drug code, drug name, dose), and usage information (drug code, drug name, dose). (3 times a day after every meal, etc.) etc. are included.

Further, in the drug weighing device 10, the control unit 11 uses the bar code reader 17 to record (described) the contained drug information including the name of the contained drug recorded (described) in the drug bottle in the drug bottle with a barcode. Read from the JAN code or medicine bottle code (described). Here, the control unit 11 when executing the reading process corresponds to the contained medicine information reading means.

The method of reading the prescription information and the contained medicine information from the prescription or the medicine bottle is not limited to the one using a barcode, and may be one using a character recognition technique or an image recognition technique.

For example, it is conceivable that the medicine bottle is provided with an information recording medium such as an RFID tag or an RFID label, and the information recording medium records information on the contained medicine including the name of the medicine contained in the medicine bottle. Be done. In this case, the drug weighing device 10 is provided with a wireless reading means such as an RFID reader that reads information from the information recording medium by wireless communication, and the control unit 11 is provided with the information recording medium in the medicine bottle. Therefore, it is conceivable to read the contained drug information by the wireless reading means.

It is also conceivable that the prescription is provided with an information recording medium such as an RFID tag or an RFID label, and the information recording medium records prescription information including the name of the prescription drug recorded on the prescription. In this case, the drug weighing device 10 is provided with a wireless reading means such as an RFID reader that reads information from the information recording medium by wireless communication, and the control unit 11 is from the information recording medium provided on the prescription. It is conceivable to read the prescription information by the wireless reading means.

It is also conceivable that the control unit 11 reads either one of the contained medicine information and the prescription information by the barcode reader 17 (code reading means) and the other by the wireless reading means. On the other hand, the drug weighing device 10 is provided with the wireless reading means in place of the barcode reader 17 (code reading means), and the control unit 11 wirelessly performs both the stored drug information and the prescription information. A configuration for reading by a reading means is also conceivable. Of course, in a configuration in which the chemical weighing device 10 includes both the barcode reader 17 (code reading means) and the wireless reading means, the control unit 11 selectively selects the barcode reader 17 or the wireless reading means. It can be used to read the contained drug information and the prescription information.

The printer 18 prints out print data input from the control unit 11 via the USB port 16. Specifically, the printer 18 is used to print a weighing result or the like by the chemical weighing device 10. The print layout of the weighing result is preset, or can be arbitrarily set in the initial setting of the chemical weighing device 10. Further, in the drug weighing device 10, the control unit 11 can input the prescription information to the printer 18 to print a bar code or a two-dimensional code indicating the prescription information together with the weighing result. Thereby, the drug packaging device 20 can execute the packaging operation according to the prescription information printed by the printer 18.

The control unit 21 is a computer including a CPU, ROM, RAM (EEPROM, etc.) and the like, and controls the chemical packaging device 20 in an integrated manner. The CPU is a processor that executes various arithmetic processes according to various programs. The ROM is a non-volatile memory in which a program such as a BIOS executed by the CPU is stored in advance. For example, the ROM stores a chemical packaging program for causing the control unit 21 to execute a chemical packaging process described later. The RAM is a volatile memory or a non-volatile memory used for the development of various programs by the CPU and the temporary storage of data in various arithmetic processes.

As shown in FIG. 4, the supply hopper 25 includes two hoppers 25A and 25B (corresponding to a charging portion) for charging powder. Then, the packaging unit 22 is divided into a division unit 221 (an example of division means) that divides the powder charged into each of the hoppers 25A and 25B into one dose unit according to the prescription information, and after the division unit 221. It is provided with a packaging unit 222 (an example of packaging means) for packaging the powdered medicine, and performs a packaging operation for packaging the powdered medicine in units of one dose. Specifically, the split unit 221 evenly distributes the powder charged into each of the hoppers 25A and 25B to the annular distribution dish rotated by the vibration feeder, and then scrapes the circular distribution dish while rotating the annular distribution dish by a predetermined angle. The operation of quantitatively discharging to the packaging unit 22 is performed. Therefore, in the packaging unit 22, one type of powder charged in either the hopper 25A or 25B is packaged in a packaging paper (medicine package) in units of one dose, or is charged in the hoppers 25A and 25B. It is possible to package the two types of powdered medicines in the same packaging paper in units of one dose. For example, the chemical packaging device 20 configured in this way is also disclosed in Japanese Patent No. 4621433. The number of hoppers provided in the supply hopper 25 may be three or more. Further, in the chemical packaging device 20, the powder is charged into the hopper 25A or the hopper 25B a plurality of times and evenly distributed to the annular distribution dish is repeated, so that the plurality of powders are packaged in a packaging paper in units of one dose. It is also possible to do.

The touch panel 23 detects an operation of a display unit such as a liquid crystal panel or an organic EL panel that displays various screens and various information according to a control instruction from the control unit 21, and an operation key displayed on the display unit. It is provided with a detection unit for inputting a detection signal to the control unit 21. That is, the touch panel 23 also serves as a display means and an input means in the chemical packaging device 20.

The RFID reader / writer 24 uses RFID wireless communication technology to record information on an RFID tag or RFID label, or reads information from the RFID tag or RFID label. The RFID reader / writer 24 is built in a predetermined position of the drug packaging device 20, and is used to read / write information to / from the RFID tag 31 when the drug sheet 30 is placed at the predetermined position.

Here, S1, S2, ... In the figure show the processing procedure (step) number executed by the control unit 11. The control unit 11 when executing the chemical weighing process corresponds to the control means according to the present invention.

The chemical weighing process is a process executed by the control unit 11 when the power of the chemical weighing device 10 is turned on. Here, the prescription includes the date of delivery of the prescription, patient ID, patient name, date of birth of the patient, dosage form information (internal use, external use, etc.), drug information (drug code, drug name, dose), usage information (1 day). The case where the information is recorded together with the two-dimensional code indicating the information, such as after every three meals, will be described as an example. Further, it is assumed that the prescription drug name includes three types of drugs, drug A, drug B, and drug C.

<Step S1>
First, in step S1, the control unit 11 waits for the reading of the prescription information (No side of S1). Specifically, the control unit 11 determines that the prescription information has been read when the two-dimensional code recorded on the prescription is read by the barcode reader 17. Then, when the user holds the two-dimensional code of the prescription over the barcode reader 17 and the two-dimensional code is read by the barcode reader 17 (Yes side of S1), the control unit 11 processes the process in step S2. To migrate to. Here, the prescription information read from the two-dimensional code includes the prescription delivery date, patient ID, patient name, patient birth date, dosage form information (internal use, external use, etc.), drug information (drug code, drug). Information recorded on the prescription, such as name, dose), usage information (such as after each meal three times a day) is included.

The barcode reader 17 is always readable when, for example, the power of the chemical weighing device 10 is turned on. It is also conceivable that the control unit 11 shifts the barcode reader 17 to a state in which it can be read for a certain period of time in response to an operation input for starting weighing with respect to the touch panel 13.

<Step S2>
In step S2, the control unit 11 causes the touch panel 13 to display the prescription screen 40 based on the prescription information read in step S1. Here, FIGS. 6 (A) and 6 (B) show an example of the prescription screen 40, respectively.

On the prescription screen 40 shown in FIG. 6A, a dispenser name, a patient name, an age, a body weight, a number of prescription days, a fraction, a drug name, a dosage form (powder / tablet), a prescription amount, and the like are displayed. Specifically, on the prescription screen 40 shown in FIG. 6A, the drug A, the drug B, and the drug C are displayed as prescription drug names on the drug display unit 401. Further, on the prescription screen 40, the dosage form of the drug A is "powder" and the prescription amount is "0.9 g", and the dosage form of the drug B is "powder" and the prescription amount is "1.2 g". Yes, it is indicated that the dosage form of the drug C is "powder" and the prescription amount is "0.6 g". Hereinafter, the display mode for displaying the drug name and the like in this way is referred to as a drug name display mode.

On the other hand, on the prescription screen 40 shown in FIG. 6B, the dispenser name, patient name, age, body weight, prescription days, fractions, etc. are displayed, but at this point, the drug name and the like are displayed on the drug display unit 401. Is not displayed. Hereinafter, the display mode in which the drug name or the like is not displayed is referred to as a drug name non-display mode. The drug name non-display mode is a display mode for causing the dispenser to perform the dispensing business while surely looking at the paper prescription by not displaying the drug name or the like on the prescription screen 40. As a result, in the drug name non-display mode, when the prescription information read from the two-dimensional code is different from the recorded content of the prescription for some reason, the dispenser can be made to recognize the defect. .. In particular, comments such as cautionary information arbitrarily recorded in the prescription may not be included in the two-dimensional code, and in such an operation in which information not included in the two-dimensional code is recorded in the prescription, dispensing is performed. The drug name non-display mode, which requires the person to see the prescription without fail, is preferable.

In the chemical weighing device 10, the control unit 11 displays an initial setting screen for the chemical weighing program in response to an operation of the touch panel 13, and the chemical name display mode or the chemical name display mode or in accordance with an operation according to the initial setting screen. The drug name non-display mode is switched.

<Step S3>
Next, in step S3, the control unit 11 waits for the reading of the name of the contained medicine (No side of S3). Specifically, the control unit 11 said that the name of the contained medicine was read when the barcode reader 17 read the JAN code recorded on the medicine bottle or the contained medicine information indicated by the medicine bottle code. to decide. Then, when the user holds the JAN code or the medicine bottle code of the medicine bottle over the barcode reader 17 and the JAN code or the medicine bottle code is read by the barcode reader 17 (Yes side of S3), the control The unit 11 shifts the process to step S4.

That is, in the drug weighing process, the prescription information is first read, and then the stored drug name is read. Therefore, if the name of the contained medicine is read first, the weighing of the medicine weighing device 10 is not started. The control unit 11 stores the weighing result when the name of the contained medicine is read first and the weighing is performed, and when the prescription information is read after that, the prescription information and the weighing are performed. Collating with the results is also considered as another embodiment.

<Step S4>
Then, in step S4, the control unit 11 branches the process according to the collation result between the stored drug name of the contained drug information read in step S3 and the stored drug name of the prescription information read in step S1. do. Specifically, the control unit 11 determines in step S4 whether or not the contained drug name corresponds to any of the prescription drug names.

Here, if the contained drug name corresponds to any of the prescription drug names (Yes side of S4), the process proceeds to step S5, and the contained drug name must correspond to any of the prescription drug names. If (No side of S4), the process proceeds to step S13.

<Step S5>
In step S5, the control unit 11 selects, among the prescription drug names included in the prescription information, the prescription drug name that matches the contained drug name as the weighing target. That is, when the contained drug name corresponds to any of the prescription drug names, the prescription drug name to be weighed is automatically selected from the prescription drug names included in the prescription information.

Therefore, the user can collate the stored drug name and the prescription drug name in the drug weighing device 10 only by having the bar code reader 17 read the JAN code or the drug bottle code recorded on the drug bottle. It is possible to realize the selection of chemicals to be weighed. Therefore, when a plurality of prescription drug names are included in the prescription information, the operation for selecting the prescription drug name to be weighed can be omitted, and the dispensing efficiency by a user such as a doctor or a pharmacist is improved. be able to.

<Step S6>
In step S6, the control unit 11 causes the touch panel 13 to display a weighing screen 41 for weighing a drug having a prescription drug name corresponding to the prescription drug name from the prescription information. At this time, the control unit 11 displays the weighing value of the medicine by the balance unit 12 and the target value of the weighing of the medicine with the name of the prescription medicine on the weighing screen 41.

Here, FIG. 7 shows an example of the weighing screen 41. The weighing screen 41 shown in FIG. 7 is displayed when the drug A is read in step S3, and has a prescription drug name “drug A” and a prescription amount target value “0.9 g”. , And the actual weighing value "0.0 g" by the balance unit 12 is displayed.

Further, on the weighing screen 41 shown in FIG. 7, a determination key 411 operated to complete weighing with respect to the prescription drug name is displayed. Here, the determination key 411 embodied on the touch panel 13 is an operation unit for inputting the completion of weighing for each prescription drug name, and is an example of the first input means according to the present invention.

Here, FIG. 16 is a diagram showing a weighing screen P16 which is another example of the weighing screen 41. In the weighing screen P16 shown in FIG. 16, when the RFID tag 31 is detected by the RFID reader / writer 14 and information can be recorded on the RFID tag 31, the control unit 11 has an image or characters to that effect. The detection display unit P161 indicated by the above is displayed. Thereby, the user can easily confirm by the display of the detection display unit P161 that the information can be written to the RFID tag 31 by the RFID reader / writer 14. If the RFID tag 31 is not detected by the RFID reader / writer 14, the control unit 11 hides the detection display unit P161. Further, it is conceivable that the control unit 11 causes the touch panel 13 to indicate that writing to the RFID tag 31 is not possible at the timing when information is originally written to the RFID tag 31. The weighing screen P16 displays information such as the name of the drug to be weighed, the usual dose, the target amount, and the current weighing value as the weighing state in the drug weighing device 10, and also displays the current weight with respect to the target amount. The barometer display unit P162 which shows the weighing value of is an image is displayed.

<Step S7>
Then, in step S7, the control unit 11 waits for the completion of weighing of the prescription drug name (No side of S7). Specifically, the control unit 11 determines that the weighing of the prescription drug name is completed by operating the determination key 411 displayed on the weighing screen 41 as shown in FIG. 7. Then, when the control unit 11 determines that the weighing of the prescription drug name is completed (Yes side of S7), the process shifts to step S8. When the weighing of the prescription drug name is completed, the control unit 11 stores the fact in a RAM or the like.

Further, in step S7, when the prescription drug name is lifted by the control unit 11 in a state where the weighing value by the balance unit 12 is continuously stable for a predetermined time (for example, 1 second). It is also conceivable to judge that the weighing of is completed. When the weighing value by the balance unit 12 is stable for the predetermined time continuously, "→" is displayed on the weighing screen shown in FIG. 7. For example, the control unit 11 can determine that the drug sheet 30 has been lifted on the condition that the weighing value by the balance unit 12 instantly becomes 0. However, when the drug sheet 30 is lifted, it becomes impossible to record information on the RFID tag 31 in step S9 described later. Therefore, it is conceivable that the control unit 11 records information (S9) on the RFID tag 31 at any time every time the weighing value by the balance unit 12 is continuously stabilized for the predetermined time. As a result, when the drug seed 30 is lifted, the final weighing value is recorded on the RFID tag 31. As a method of writing information to the RFID tag 31, when the drug sheet 30 is placed on the drug weighing device 10, information other than the weighing value by the balance unit 12 is written, and then the weighing value is written. It is conceivable to update only at any time. As a result, even if the time from when the weighed value stabilizes for a predetermined time until the drug sheet 30 is lifted is short, the weighed value can be updated to the latest information in that short time. ..

<Step S8>
In step S8, the control unit 11 causes the touch panel 13 to display a progress screen 42 showing the progress of weighing the prescription drug name in the prescription information. Here, FIGS. 8 (A) and 8 (B) show an example of the progress screen 42, respectively.

FIG. 8A shows an example of the progress screen 42 displayed when the weighing of the drug A is completed in the drug name display mode. In the progress screen 42 shown in FIG. 8A, among the drug names displayed on the drug name display unit 401, the drug names for which weighing has already been completed are displayed in a different color or highlight.

FIG. 8B shows an example of the progress screen 42 displayed when the weighing of the drug A is completed in the drug name non-display mode. On the progress screen 42 shown in FIG. 8B, only the names of the chemicals for which weighing has already been completed are displayed.

Further, on the progress screen 42 shown in FIGS. 8A and 8B, a completion key 421 operated to complete the weighing related to the prescription information is displayed. Here, the completion key 421 embodied on the touch panel 13 is an operation unit for inputting the completion of weighing for each prescription information, and is an example of the second input means according to the present invention.

<Step S9>
Further, in step S9, the control unit 11 writes the prescription information and the weighing result (an example of weighing drug information) on the RFID tag 31 by the RFID reader / writer 14. Here, the control unit 11 when executing the relevant process corresponds to the recording means.

For example, the prescription information includes prescription delivery date, patient ID, patient name, patient birth date, dosage form information (internal use, external use, etc.), drug information (drug code, drug name, dose), usage information (drug code, drug name, dose). It contains information recorded on the prescription, such as (eg, three times a day after each meal). In addition, the weighing result includes the name of the drug to be weighed, the target value for weighing, the actual weighing value, the collation result between the name of the prescription drug and the name of the contained drug, and the like. Further, when the prescription drug name included in the prescription information is replaced with the generic drug name and weighed, the information to that effect is also included in the weighing result.

In step S9, the control unit 11 may have the RFID tag 31 record only a part of the prescription information. For example, when the RFID tag 31 having a small storage capacity is used, it is not possible to record all the prescription information and the weighing result information. Therefore, in this case, the control unit 11 may store at least the name of the drug to be weighed in the RFID tag 31. As a result, as will be described later, it is possible to prevent mistakes in the hopper in the chemical packaging device 20. In this case, the drug weighing device 10 and the drug packaging device 20 are communicably connected via a communication network such as a LAN or the Internet, and the control unit 11 stores information that is not recorded in the RFID 31 in the drug packaging. It is conceivable to transmit to the device 20.

Further, in the configuration in which the drug weighing device 10 and the drug packaging device 20 are connected by the communication network, the prescription information and the simple fixed information stored in association with the weighing result in the drug weighing device 10 (simple fixed information). It is also conceivable to have the RFID tag 31 record the information identification number and the like). In this case, when the fixed information is read by the drug packaging device 20, the drug packaging device 20 transmits the prescription information corresponding to the fixed information and the weighing result to the drug weighing device 10. The request is made. As a result, the prescription information corresponding to the fixed information and the weighing result are transmitted from the drug weighing device 10 to the drug packaging device 20 via the communication network.

The processing procedures of step 8 and step S9 may be executed in the reverse order of execution or may be executed substantially in parallel. That is, the prescription information and the weighing result may be recorded on the RFID tag 31 in the RFID tag 31 in the step S9 immediately after the weighing is determined to be completed in the step S7.

<Step S10>
After that, in step S10, the control unit 11 determines whether or not the next contained drug name has been read by the barcode reader 17. Here, when the control unit 11 determines that the next contained drug name has been read (Yes side of S10), the process shifts to the step S4. On the other hand, if the name of the next contained medicine cannot be read (No side of S10), the control unit 11 shifts the process to step S11.

<Step S11>
In step S11, the control unit 11 determines whether or not all the weighings corresponding to the prescription information have been completed. Specifically, the control unit 11 operates the completion key 421 displayed on the progress screen 42 as shown in FIGS. 8A and 8B, or all included in the prescription information. When the weighing of the drug to be weighed is completed, it is determined that all the weighing related to the prescription information is completed.

Then, when the control unit 11 determines that all the weighing related to the prescription information is completed (Yes side of S11), the process shifts to step S12. On the other hand, if the control unit 11 has not completed all the weighings related to the prescription information (No side of S11), the control unit 11 shifts the process to the step S10.

By the way, when the completion key 421 is operated, if the prescription drug name included in the prescription information includes a prescription drug name for which weighing has not been completed, the user may have forgotten to weigh. Therefore, when the control unit 11 determines that the operation of the completion key 421 has been performed in the step S11, the prescription included in the prescription information in which the completion of weighing is input by the operation of the completion key 421. If there is a prescription drug name for which the completion of weighing has not been input by the determination key 411 among the drug names, it is conceivable to display that fact on the touch panel 13. This makes it possible to warn the user of forgetting to weigh. The control unit 11 determines whether or not the weighing of each of the prescription drug names is completed according to the information stored in the RAM in the step 7. Here, the control unit 11 when executing the display process corresponds to the incomplete display means. Further, the control unit 11 may display the display by characters, images, voice, or light.

However, it is conceivable that the prescription information includes chemicals such as external medicines, liquid medicines, tablets, and heat agents (prescribed amounts of powders or tablets packaged) that are not subject to weighing by the chemical weighing device 10. In this case, since it is normal that the weighing of the chemicals not subject to weighing by the chemical weighing device 10 is incomplete, the user is not warned of forgetting to weigh. However, if necessary, it is conceivable to display a warning of forgetting to weigh the chemicals that are not subject to weighing in the chemical weighing device 10. This makes it possible to reliably prevent the user from forgetting to weigh.

For example, when the prescription drug name included in the prescription information includes a prescription drug name whose weighing has not been completed, the control unit 11 may display the warning only when the prescription drug name is powdered drug. Conceivable. This is because the powder is likely to be weighed by the drug weighing device 10 and the user is likely to forget to weigh it.

Further, it is conceivable that the data storage unit 15 or the like stores in advance the types of chemicals that are not subject to weighing by the chemical weighing device 10. For example, it is conceivable that the heat agent is stored as a drug type that is not subject to weighing. As a result, the control unit 11 can not display the warning when the weighing of the prescription drug name corresponding to the drug type not subject to the weighing is incomplete. As a result, it is possible to display a warning only when necessary and prevent unnecessary warning display. Of course, a configuration is also conceivable in which the drug type to be weighed is stored in advance in the data storage unit 15 instead of the drug type not to be weighed by the drug weighing device 10.

Here, these methods of displaying the warning of forgetting to weigh can be arbitrarily switched according to the operation input of the touch panel 13 according to the initial setting screen for the drug weighing program displayed by the control unit 11. Conceivable.

It is also conceivable that the control unit 11 automatically determines in step S11 that the weighing of the prescription information has been completed. This saves the user the trouble of operating the completion key 421.

For example, it is conceivable that the control unit 11 determines that the weighing of the previous prescription information has been completed on condition that the next prescription information has been read. That is, the control unit 11 determines that the weighing of the previously read prescription information has been completed on condition that the two-dimensional code of the prescription has been read by the barcode reader 17.

Further, it is also conceivable that the control unit 11 determines that the weighing of all the prescription drug names included in the prescription information has been completed, on condition that the weighing of all the prescription drug names has been completed. Thereby, if all the prescription drug names included in the prescription information are the drugs to be weighed by the drug weighing device 10, it is possible to automatically determine that the weighing corresponding to the prescription information is completed. Is.

On the other hand, when the prescription information includes a drug that is not subject to weighing by the drug weighing device 10, it cannot be determined whether or not the weighing related to the prescription information is completed. Therefore, it is conceivable to store the types of chemicals that are not subject to weighing by the chemical weighing device 10 in the data storage unit 15 or the like. As a result, the prescription unit 11 completes the weighing of the prescription drug names included in the prescription information in the prescription information in step S11, which does not correspond to the drug type not subject to the weighing. It can be determined that the weighing corresponding to the information is completed. Of course, a configuration is also conceivable in which the drug type to be weighed is stored in advance in the data storage unit 15 instead of the drug type not to be weighed by the drug weighing device 10.

<Step S12>
Then, when all the weighing related to the prescription information is completed, in the following step S12, the control unit 11 causes the printer 18 to print the prescription information and the weighing result. At this time, the control unit 11 prints only the preset information of the prescription information and the weighing result according to the preset layout.

Specifically, the patient name included in the prescription information read in step S1, the name of the drug to be weighed, the weighing target value, the actual weighing value in the drug weighing device 10, the prescription drug name and the accommodation. The collation result with the drug name, weighing time, weighing worker, etc. are printed. That is, the control unit 11 causes the printer 18 to print only the records relating to the chemicals weighed by the chemical weighing device 10. In the drug weighing device 10, since the prescription information and the weighing result are recorded on the RFID tag 31, it is not necessary to print by the printer 18 every time the prescription drug is weighed, and the weighing related to the prescription information is performed. The weighing result may be printed when completed. Of course, it is also conceivable that the control unit 11 prints the weighing result on the printer 18 every time the prescription drug is weighed.

<Step S13>
On the other hand, in step S4, when the contained drug name read in step S3 does not correspond to any of the prescription drug names (No side of S4), the control unit 11 executes the processes after step S13. ..

First, in step S13, the control unit 11 determines whether or not the stored drug name is registered in the drug master stored in the data storage unit 15. Here, when it is determined that the name of the contained drug is registered in the drug master (Yes side of S13), the control unit 11 shifts the process to step S14. On the other hand, when it is determined that the name of the contained drug is not registered in the drug master (No side of S13), the control unit 11 shifts the process to step S15.

<Step S14>
In step S14, as shown in FIG. 9A, the control unit 11 displays a warning screen 43 indicating that the chemicals are different on the touch panel 13, and returns the process to step S3. As a result, it is possible to warn the user that the selection of the medicine bottle is incorrect, and it is possible to prevent the wrong prescription of the medicine. The warning is not limited to the display of characters and images on the touch panel 13. For example, the chemical weighing device 10 may have a speaker, and the control unit 11 may display that the chemical is different by voice depending on the speaker. Further, the chemical weighing device 10 may have an LED for warning display, and the control unit 11 may display that the chemical is different by light depending on whether the LED is lit or blinking.

<Step S15>
In step S15, the control unit 11 determines whether or not the name of the contained drug corresponds to any of the generic drug names of the generic drug master stored in the data storage unit 15. Here, when it is determined that the contained drug name corresponds to any of the generic drug names (Yes side of S15), the control unit 11 shifts the process to step S16. On the other hand, when it is determined that the contained drug name does not correspond to any of the generic drug names (No side of S15), the control unit 11 shifts the process to step S19.

<Step S16>
In step S16, the control unit 11 determines whether or not the name of the original drug corresponding to the name of the generic drug that matches the name of the contained drug corresponds to any of the names of the prescription drugs. That is, in the step S16, the control unit 11 determines whether or not the drug having the name of the contained drug is a generic drug corresponding to the drug having the name of the prescription drug.

Here, when it is determined that the name of the original drug corresponds to any of the names of the prescription drugs (Yes side of S16), the control unit 11 shifts the process to step S17. On the other hand, when it is determined that the name of the original drug does not correspond to any of the names of the prescription drugs (No side of S16), the control unit 11 shifts the process to step S19.

It is also conceivable that the name of the generic drug is recorded as the name of the prescription drug on the prescription. Therefore, in step S15, it is determined whether or not the contained drug name corresponds to either the original drug name or the generic drug name, and in step S16, the corresponding innovator drug name or generic drug name is used. It is also conceivable as another embodiment to determine whether or not the corresponding generic drug name or the original drug name corresponds to any of the above-mentioned prescription drug names.

<Step S17>
In step S17, the control unit 11 displays a confirmation screen 44 to the effect that the drug with the generic drug name is used. Here, FIG. 9B shows an example of the confirmation screen 44. As shown in FIG. 9B, the confirmation screen 44 displays that the drug with the name of the contained drug is a generic drug and an inquiry as to whether or not to approve the use of the generic drug. Further, on the confirmation screen 44, an approval key 441 operated when approving the use of the generic drug and a cancel key 442 operated when the use of the generic drug is not approved are displayed.

<Step S18>
Then, in step S18, the control unit 11 determines whether or not the use of the generic drug is approved. Specifically, the control unit 11 determines whether the approval key 441 or the cancel key 442 is selected in the step S18.

Here, when the cancel key 442 is operated, the control unit 11 determines that the use of the generic drug has not been approved (No side of S18), and shifts the process to the step S3.

Further, when the approval key 441 is operated, the control unit 11 determines that the use of the generic drug is approved (Yes side of S18), and shifts the process to the step S5. As a result, in step S5, the control unit 11 selects the prescription drug name corresponding to the generic drug name from the prescription drug names included in the prescription information as the weighing target, and in step S6, the prescription drug name is described. The weighing screen 41 showing the name of the generic drug and the weighing target value thereof is displayed on the touch panel 13. When the prescription amount of the generic drug name for producing the same efficacy as the prescription amount for the generic drug name is different, the control unit 11 sets the prescription amount of the generic drug name based on the generic drug master. It is conceivable to calculate the prescribed amount of the corresponding generic drug name as the weighing target value.

<Step S19>
On the other hand, when the contained drug name does not correspond to either the prescription drug name or the generic drug name (No side of S4, No side of S15), the control unit 11 executes the processes after step S19. Further, even when the name of the original drug corresponding to the name of the generic drug that matches the name of the contained drug does not correspond to any of the names of the prescription drugs (No side of S16), the control unit 11 is in step S19 or later. Execute the process.

In step S19, the control unit 11 causes the touch panel 13 to display a warning screen 45 indicating that the chemicals are different. As a result, it is possible to warn the user that the selection of the medicine bottle is incorrect, and it is possible to prevent the wrong prescription of the medicine. The warning is not limited to the display of characters and images on the touch panel 13. For example, the chemical weighing device 10 may have a speaker, and the control unit 11 may display that the chemical is different by voice depending on the speaker. Further, the chemical weighing device 10 may have an LED for warning display, and the control unit 11 may display that the chemical is different by light depending on whether the LED is lit or blinking.

Here, FIG. 9C shows an example of the warning screen 45. As shown in FIG. 9C, the warning screen 45 displays the fact that the drug is different and an inquiry as to whether or not to register the generic drug name. Further, on the warning screen 45, a generic drug registration key 451 operated when the generic drug registration is performed and a cancel key 452 operated when the generic drug registration is not performed are displayed.

<Step S20>
Then, in step S20, the control unit 11 determines whether or not the operation to register the generic drug has been performed. Specifically, the control unit 11 determines whether the generic drug registration key 451 or the cancel key 452 is selected in step S20.

Here, when the cancel key 452 is operated, the control unit 11 determines that the generic drug registration is not performed (No side of S20), and shifts the process to the step S3. Further, when the generic drug registration key 451 is operated, the control unit 11 determines that the generic drug registration is to be performed (Yes side of S20), and shifts the process to step S21.

<Step S21>
Then, in step S21, the control unit 11 executes a process for editing the generic drug master. For example, the control unit 11 displays a registration screen 51 for registering the generic drug name in the generic drug master on the touch panel 13, and responds to an operation input according to the display of the registration screen 51 to display the generic drug. Register your name. Further, the control unit 11 corrects the correspondence relationship between the generic drug name and the generic drug name in the already registered generic drug master according to the operation input by the user of the touch panel 13.

Here, FIGS. 10A and 10B show an example of the registration screen 51. As shown in FIG. 10A, on the initial screen of the registration screen 51, items such as a drug code, a drug name, a category, a specific gravity, a drug type, a compounding change, an excipient, a unit, and a weighing can be set. .. Then, the control unit 11 registers the generic drug name in the generic drug master in response to the operation of the registration key 511, and closes the registration screen 51 in response to the operation of the return key 512. Further, the control unit 11 switches the display content of the registration screen 51 according to the operation of the previous page key 513 or the next page key 514. Specifically, when the next page key 514 is operated, the control unit 11 sets the setting items on the registration screen 51 to the original drug name, JAN code, and drug bottle code, as shown in FIG. 10 (B). Change to. Further, in FIG. 10B, the JAN uptake key 515 and the normal dose key 516 are displayed. The control unit 11 captures the JAN code from the barcode attached to the medicine bottle by the barcode reader 17 in response to the operation of the JAN capture key 515. In addition, the control unit 11 opens a regular dose setting screen for setting a regular dose corresponding to the generic drug name in response to an operation of the regular dose key 516, and regularly uses it in response to an input on the regular dose setting screen. Set the amount. The normal dose is an amount that can be expected to have a therapeutic effect when the drug is most commonly used.

After that, the control unit 11 shifts the process to the step S15. That is, the user can temporarily suspend the weighing work related to the prescription information, edit the generic drug master, and then resume the weighing work related to the prescription information as it is. Therefore, the user can appropriately edit the generic drug master and enhance its contents in the daily operation using the drug weighing device 10. On the other hand, when the weighing work based on the prescription information (drug weighing process) is temporarily terminated and the generic drug master is edited on the initial setting screen or the like, then the weighing work based on the prescription information (drug weighing process) is performed. ) Must be repeated from the beginning, forcing the user to do complicated work.

As described above, the user using the drug weighing device 10 can accurately and easily read the two-dimensional code of the prescription and the bar code of the drug bottle by the bar code reader 17 so that the drug according to the prescription can be accurately and easily read. Weighing can be done.

In particular, when the user causes the bar code reader 17 to read the bar code of the medicine bottle, the medicine weighing device 10 collates the name of the contained medicine and the name of the prescription medicine, and the weighing target is to be started to be weighed. The prescription drug name is selected. Therefore, when a plurality of prescription drug names are recorded in the prescription, the user can save the trouble of selecting the prescription drug name to be weighed.

[Chemical packaging processing]
Subsequently, with reference to the flowchart of FIG. 11, an example of the procedure of the chemical packaging process executed by the control unit 21 according to the chemical packaging program will be described. Here, S31, S32, ... In the figure show the processing procedure (step) number executed by the control unit 21.

<Step S31>
First, in step S31, the control unit 21 determines whether or not the prescription information is input. Specifically, the control unit 21 determines whether or not the prescription information has been read from the RFID tag 31 by the RFID reader / writer 24. As described above, in the drug weighing system 1, since the prescription information can be read from the RFID tag 31 by the drug packaging device 20, the drug packaging device 20 can be communicably connected to a higher-level system such as a dispensing support system. You don't have to. Further, in the drug packaging device 20, since the prescription information is acquired from the RFID tag 31, the user has conventionally performed the work of inputting the prescription information in the drug packaging device 20 and operating the drug packaging device 20. Operation work can be reduced.

However, another embodiment may be considered in which the chemical packaging device 20 is communicably connected to the higher-level system. In this case, the control unit 21 determines in step S31 whether or not the prescription information has been input from the higher-level system. Further, another embodiment may be considered in which the control unit 21 includes a barcode reader that reads prescription information from the two-dimensional code recorded on the prescription. In this case, the control unit 21 determines in step S31 whether or not the two-dimensional code has been read. Of course, the drug packaging device 20 has a plurality of input functions for inputting the prescription information by these different methods, and a configuration in which any of the input functions can be selected in advance is also conceivable.

Here, when the control unit 21 determines that the prescription information has been input (Yes side of S31), the process shifts to step S32, and when it determines that the prescription information has not been input (S31). No side), the process is shifted to step S33.

<Step S32>
In step S32, the control unit 21 selects whether to use the hopper 25A or the hopper 25B in packaging the drug related to the prescription information read in step S31.

For example, when the prescription information describing the drug to be prescribed to the patient C1 is input, the hopper 25A is used for packaging the drug, and when the prescription information describing the drug to be prescribed to the patient C2 is input. It is conceivable that it is predetermined that the hopper 25B will be used for packaging the drug, and that the prescription information includes allocation information indicating that fact. In this case, in step S32, the control unit 21 can determine whether to use the hopper 25A or the hopper 25B according to the allocation information included in the prescription information.

Further, each time the prescription information is read from the RFID tag 31, the control unit 21 automatically assigns whether to use the hopper 25A or the hopper 25B for each prescription information in the step S32. Is also possible. For example, the control unit 21 may select to use the hopper 25A and the hopper 25B alternately each time the prescription information is input.

In the medicine packaging device 20 configured in this way, the user can use the hopper 25A and the hopper 25B properly for each of the prescription information to input the medicine, so that the dispensing work related to the prescription information of a plurality of patients can be performed. You can proceed in parallel.

However, if the dispensing work related to the prescription information of a plurality of patients is carried out in parallel, there is a possibility that the user may inject the medicine into the hopper 25A or the hopper 25B which is the opposite of the original one. Therefore, in the chemical packaging process, the process of the following step S33 or less prevents the user from making a mistake in determining the destination of the chemical.

<Step S33>
In step S33, the control unit 21 determines whether or not the drug name (hereinafter referred to as “input drug name”) of the drug placed on the drug sheet 30 has been read from the RFID tag 31. When the prescription information is read from the RFID tag 31 in the step S31, the input drug name is also read at the same time, so that it is determined that the input drug name has been read in the step 33.

Here, when the input drug name is read (Yes side of S33), the control unit 21 shifts the process to step S34, and until the input drug name is read (No side of S33), The process shifts to step S31.

<Step S34>
Then, in step S34, the control unit 21 selects whether to use the hopper 25A or the hopper 25B based on the prescription information and the input drug name. For example, in step S32, it is set that the hopper 25A is used for packaging the medicine prescribed for the patient C1, and the hopper 25B is used for the packaging of the medicine prescribed for the patient C2. In this case, in step S34, when the input drug name included in the prescription information corresponding to patient C1 is read, the hopper 25A is selected, and the input drug name included in the prescription information corresponding to patient C2 is read. And the hopper 25B are selected.

Even if the prescription information is not recorded on the RFID tag 31, in step S32, the prescription information input from the higher-level system or the prescription information read from the two-dimensional code of the prescription is used as the basis for the prescription information. Whether to use the hopper 25A or the hopper 25B is selected. Therefore, if the RFID tag 31 stores at least information such as a drug name and a weighed value related to the drug placed on the drug sheet 30, the control unit 21 will perform the step S34 based on the information. You can make a judgment. Specifically, the control unit 21 identifies prescription information including the prescription drug name and the prescription amount corresponding to the drug name and the weighed value related to the drug placed on the drug sheet 30, and corresponds to the prescription information. Select either the hopper 25A or the hopper 25B.

<Step S35>
In step S35, the control unit 21 causes the touch panel 23 to display the selection result in step S34 by characters or images. For example, the control unit 21 may display a guidance such as "Please put the chemical A into the hopper A". The display is performed to notify the user of either the hopper 25A or the hopper 25B, and is not limited to the display on the touch panel 23.

For example, the control unit 21 may display the selection result by voice. Further, it is also conceivable to provide LEDs or the like in each of the hopper 25A and the hopper 25B, and display the selection result by turning on any of the LEDs by the control unit 21. Further, if the input port of the hopper 25A and the hopper 25B can be opened and closed by a predetermined drive means, the control unit 21 controls the drive means to obtain any of the input ports of the hopper 25A and the hopper 25B. It is also conceivable to display the selection result by opening the mouth. Further, each of the hopper 25A and the hopper 25B is provided with a locking means for restricting the opening of the loading port, and the control unit 21 releases only one of the locking means to release the other. By setting the locked state, it is conceivable that the user can open only the charging port to which the medicine of the medicine sheet 30 should be charged.

As described above, in the drug packaging device 20, the drug is charged based on the information stored in the RFID tag 31 provided on the drug sheet 30, which is inseparable from the drug weighed by the drug weighing device 10. The destination is automatically displayed. Therefore, the user can easily grasp the charging destination of the chemical, and the error of the charging destination of the chemical is prevented. Further, if any two or more of various notification methods such as the display on the touch panel 23, the voice display, and the LED display are used in combination as the notification method of the selection result in step S34, the user can input the chemicals. The error can be prevented more effectively.

<Step S36>
After that, in step S36, the control unit 21 controls the packaging operation executed by the packaging unit 22 according to preset control conditions based on the prescription information read from the RFID 31 and the weighing result. .. Here, the control unit 21 when executing the relevant process corresponds to the packaging control means.

In the conventional chemical packaging device, since detailed information on the chemicals to be packaged is unknown, the chemicals are packaged according to the common condition that all the chemicals can be accurately packaged. Therefore, for example, the packaging operation may be unnecessarily slowed down. However, in the drug packaging process, in step S36, different packaging operation controls can be executed based on the prescription information and the weighing result. Therefore, for example, the drug is packaged under conditions suitable for each drug. Can be done. Specifically, the control unit 21 is preset for each type of powder according to the prescription information read from the RFID tag 31 as the weighing drug information and the type of the drug contained in the weighing result. The operation is performed by the dividing means or the packaging means. For example, when packaging a powder of a type that is easily scattered, the control unit 21 slows the packaging speed (such as the rotation speed of the annular distribution dish in the division unit 221) to prevent scattering and makes it difficult to disperse. When packaging different types of powdered medicine, it is conceivable to speed up the packaging by increasing the packaging speed.

[Other examples of chemical packaging processing]
Here, the first modification to the third modification, which is another example of the chemical packaging process, will be described with reference to FIGS. 12 to 14. The same processing procedure as that of the chemical packaging processing described with reference to FIG. 11 is designated by the same reference numerals and the description thereof will be omitted.

[First modification]
As shown in FIG. 12, in the chemical packaging process according to the first modification, steps S311 to S312 described later are executed by the control unit 21 between the steps S31 and S32 shown in FIG. ..

<Step S311>
In step S311 the control unit 21 determines whether or not the prescription information input in step S31 includes a plurality of prescription drug names. Here, when the control unit 21 determines that a plurality of prescription drug names are included (Yes side of S311), the process is shifted to step S312, and when it is determined that the plurality of prescription drug names are not included (the control unit 21). (No side of S311), the process is shifted to the step S32.

<Step S312>
In step S312, the control unit 21 selects whether to use the hopper 25A or the hopper 25B for each prescription drug name included in the prescription information. Regarding the selection method, for example, the prescription information includes allocation information regarding whether to use the hopper 25A or the hopper 25B for each prescription drug name, and the control unit 21 includes the prescription information. It is conceivable to determine whether to use the hopper 25A or the hopper 25B according to the included allocation information. Specifically, it is conceivable that whether to use the hopper 25A or the hopper 25B for each color (red, white, etc.) of the drug is predetermined for each medical facility or pharmacy. For example, it is conceivable to specify that the hopper 25A and the hopper 25B should be used properly for a colored chemical and a colorless chemical that is not colored. Further, the control unit 21 automatically determines whether to use the hopper 25A or the hopper 25B for each prescription drug name, such as alternately using the hopper 25A and the hopper 25B for each prescription drug name. It is also possible to assign to.

Further, when the prescription information contains two prescription drug names predetermined as drugs to be contained in the same packing paper among a plurality of prescription drug names, the control unit 21 controls the two drugs. Choose to use the hopper 25A on the one hand and the hopper 25B on the other. As a result, in the drug packaging operation by the packaging unit 22 of the drug packaging device 20 in step S36, the prescription drugs charged into each of the hopper 25A and the hopper 25B are packaged in the same packaging paper in units of one dose. Can be made to. For example, when one prescription information contains two types (plurality of types) of medicines taken at different times, the medicine packaging device 20 operates as follows. Specifically, consider the case where the powder M1 to be taken in the morning, noon, and evening and the powder M2 to be taken in the morning and evening are included in one prescription information. In this case, in the drug packaging operation in step S36, the control unit 21 refers to the timing of taking each of the powders M1 and M2 from the prescription information, and the powder M1 and the powder M2 are referred to as “the morning of the powder M1”. And the morning of the powder M2, the afternoon of the powder M1, the evening of the powder M1 and the evening of the powder M2 are packaged in the same packaging paper. This is a function that can be realized by the control unit 21 referring to the time of taking each drug from the prescription information recorded on the RFID tag 31. Since the prescription information is acquired from the RFID tag 31 in the drug packaging device 20, the prescription information input work in the drug packaging device 20 and the drug packaging device 20 that have been conventionally performed by the user are operated. Operation work is reduced.

As described above, according to the first modification, when a plurality of prescription drug names are included in one prescription information corresponding to one patient, the hopper 25A and the hopper 25B are included for each prescription drug name. Can be used properly, and the dispensing work of multiple prescription drugs can be carried out in parallel. If there are prescription drugs to be packaged at the same time, the hoppers 25A and 25B can be used at the same time to package the prescription drugs in the same packaging paper in units of one dose.

[Second modification]
As shown in FIG. 13, in the chemical packaging process according to the second modification, after the step S32 and the step S312 in the chemical packaging process according to the first modification shown in FIG. 12, the control unit 21 Steps S313 to S315 described later are executed.

<Step S313>
In step S313, the control unit 21 determines whether or not there is unfinished prescription information for which the drug packaging operation executed in step S36 has not been completed for all the drugs. Here, when the control unit 21 determines that the unfinished prescription information exists (Yes side of S313), the process shifts to step S314, and when the unfinished prescription information does not exist (S313). No side), the process is shifted to the step S33.

<Step S314>
In step S314, the control unit 21 determines whether or not the hopper used in the drug packaging operation for the incomplete prescription information has been selected. In addition, when it is simply referred to as a "hopper", it means either one or both of the hoppers 25A and 25B. When the hopper used in the drug packaging operation related to the incomplete prescription information or the hopper to be used is not selected (No side of S314), the control unit 21 shifts the process to the step S33. Let me. As a result, both the hopper 25A and the hopper 25B are used, for example, when there is no drug to be wrapped in the same packaging paper in the incomplete prescription information, or when there is only one remaining drug. When it is not necessary, the hopper 25A and the hopper 25B can be used in the dispensing operation of the medicine described in the different prescription information.

On the other hand, when it is determined that the hopper used in the drug packaging operation related to the incomplete prescription information or the hopper to be used is selected (Yes side of S314), the process proceeds to step S315.

<Step S315>
In step S315, the control unit 21 makes the process wait until the drug packaging operation related to the incomplete prescription information is completed, and then shifts the process to the step S33. In this case, the control unit 21 may display an error for notifying the user that there is no usable hopper by characters, images, voice, light, or the like.

As a result, when it is necessary to use the hopper 25A and the hopper 25B together, for example, when there is a drug to be wrapped in the same packaging paper in the unfinished prescription information, it is described in other prescription information. It is possible to prohibit the use of the hopper 25A and the hopper 25B in the chemical packaging operation related to the chemicals. Further, when there are two or more remaining drugs included in the incomplete prescription information, the interruption of the next prescription information is prevented, so that the prescription information can be sequentially processed and dispensing errors are prevented. can do.

[Third modification example]
As shown in FIG. 14, in the chemical packaging process according to the third modification, steps S341 to S343 described later are executed by the control unit 21 instead of the steps S34 to S35 shown in FIG.

Here, the chemical packaging device 20 on which the chemical packaging process according to the third modification is executed is an individual RFID reader / writer 24 provided at a position corresponding to each of the plurality of the hopper 25A and the hopper 25B. Must be equipped. Hereinafter, the RFID reader / writer 24 provided at a position corresponding to the hopper 25A is referred to as an RFID reader / writer 24A, and the RFID reader / writer 24 provided at a position corresponding to the hopper 25B is referred to as an RFID reader / writer 24B. More specifically, the RFID reader / writer 24A is a mounting table for the drug sheet 30 provided in the vicinity of the loading port of the hopper 25A (for example, the lid of the loading port), and the RFID reader / writer 24B is the hopper 25B. It is arranged on a mounting table of the drug sheet 30 provided in the vicinity of the charging port.

<Step S341>
In step S341, the control unit 21 determines whether or not the hopper in which the user is trying to inject the drug in the drug sheet 30 is correct.

Specifically, the control unit 21 allows the user to use the drug in the drug sheet 30 depending on whether the RFID reader / writer 24 or the RFID reader / writer 24B reads the input drug name from the RFID tag 31. Determine the hopper you are about to throw in. Then, in the control unit 21, whether the hopper 25A or the hopper 25B provided with the RFID reader / writer 24 or the RFID reader / writer 24B that has read the input drug name is the hopper selected in step S32. Judge whether or not.

Here, when the control unit 21 determines that the hopper in which the drug in the drug sheet 30 is to be charged is correct (Yes side of S341), the control unit 21 shifts the process to step S342 and determines that the process is incorrect (S341). No side), the process is shifted to step S343.

<Step S342>
In step S342, the control unit 21 notifies the user that the hopper who is trying to put the medicine in the medicine sheet 30 is correct. Specifically, the control unit 21 may display to that effect on the touch panel 23. It is also conceivable that the control unit 21 lights the LEDs and the like provided on the hopper 25A and the hopper 25B in a predetermined color (blue, green, etc.) corresponding to the case where the hopper is correct. Of course, it is also conceivable that the hopper will display the correctness by voice or the like. Further, the control unit 21 may automatically open the charging port of the hopper or unlock the charging port of the hopper only when the hopper in which the drug of the drug sheet 30 is to be charged is correct. Conceivable.

<Step S343>
On the other hand, in step S343, the control unit 21 notifies the user that the hopper trying to put the medicine in the medicine sheet 30 is wrong. Specifically, the control unit 21 may display to that effect on the touch panel 23. Further, it is conceivable that the control unit 21 lights the LEDs and the like provided on the hopper 25A and the hopper 25B in a predetermined color (red or the like) corresponding to the case where the hopper is erroneous. Of course, it is also possible to display the fact that the hopper is wrong by voice or the like.

As described above, according to the third modification, the user places the drug sheet 30 in a position where the RFID reader / writer 24A or the RFID reader / writer 24B is provided, whereby the drug sheet 30 is placed. Since it is possible to confirm the suitability of the charging destination of the chemicals placed on the drug sheet 30, it is possible to effectively prevent an error in the charging destination of the chemicals placed on the drug sheet 30.

In the third modification, the steps S341 to S343 are executed in place of the steps S34 to S35 in the chemical packaging process (see FIGS. 12 and 13) according to the first modification and the second modification. It is also possible. As a result, for example, when the prescription information contains a plurality of drugs, the user can determine whether or not the destination of the drug in the drug sheet 30 is appropriate as a hopper selected for each drug (S312). Can be easily confirmed.

[Other functions]
Hereinafter, other functions of the chemical weighing device 10 will be described.

[Prescription information input mode]
In the drug weighing device 10, the input mode of the prescription information can be arbitrarily selected. For example, the control unit 11 displays the initial setting screen for the chemical weighing program on the touch panel 13, and selects the input mode according to the operation input performed according to the initial setting screen.

The input mode includes a barcode reading mode for reading the prescription information using the bar code reader 17, a manual input mode for manually inputting the prescription information using the touch panel 13, and a higher-level system of the drug weighing device 10. A network input mode for inputting the prescription information via a communication network is included. When the drug weighing device 10 has the network input mode, the drug weighing device 10 provides a communication interface for communicating with a higher-level system such as a dispensing support system via a communication network such as LAN or the Internet. Be prepared. Then, the control unit 11 executes the same processing procedure as the chemical weighing process (see FIG. 5) even in the network input mode, for example. That is, reading the prescription information from the prescription in step S1 only replaces the input of the prescription information from the higher-level system. Further, in the case of an input mode such as the manual input mode or the network input mode, the control unit 11 automatically reads the barcode on condition that the two-dimensional code is read by the barcode reader 17. It is also possible to shift to the mode.

Further, it is conceivable that the chemical weighing device 10 has a microphone for inputting voice and a voice recognition means for executing voice recognition processing for inputting information according to the voice input to the microphone. The voice recognition means is, for example, the control unit 11 when executing the voice recognition process. In such a configuration, the dispensing operator or the like reads out the contents of the prescription printed on paper or the handwritten prescription aloud, and the control unit 11 reads the prescription information recorded in the prescription to the drug weighing device. You can enter in 10. That is, it is conceivable that the drug weighing device 10 includes a voice input mode for inputting the prescription information by voice as the input mode. At this time, the control unit 11 collectively reads out the prescription information recorded in the prescription, and after the information regarding the plurality of drug names is input to the drug weighing device 10, the plurality of prescription information is in accordance with the prescription information. It is conceivable to continuously weigh the drug name of. It is also conceivable that the control unit 11 may perform weighing for the drug name each time one of the prescription information recorded in the prescription is read aloud.

[Prescription batch reading mode]
The drug weighing process (see FIG. 5) is a processing procedure in which prescription information is read from one prescription and each prescription drug name included in the prescription information is weighed in order. On the other hand, it is conceivable that the drug weighing device 10 is provided with a prescription batch reading mode capable of continuously reading prescription information from a plurality of prescriptions and proceeding with weighing for each of the prescription information in parallel. The prescription batch reading mode is realized by executing the drug weighing program by the control unit 11.

Specifically, in the prescription batch reading mode, substantially the same processing as the drug weighing process is executed, but when the stored drug name is not read in the step S3 (No side of S3), the said. The control unit 11 shifts the process to step S1. As a result, the user can have the barcode reader 17 read a plurality of prescriptions in succession. Then, the control unit 11 stores and stores the prescription information read from the plurality of prescriptions in a RAM or the like. Here, FIG. 15A shows prescription information read from a plurality of prescriptions D1 to D3. The prescription D1 contains drugs A to C, the prescription D2 contains drugs D to drug F, and the prescription D3 contains drugs G to I.

After that, when the contained drug name is read (Yes side of S3), in the next step S4, the control unit 11 has one of the prescription drug names in which the contained drug name is a plurality of the prescription information. Judge whether or not it corresponds to. Specifically, when the prescriptions D1 to D3 shown in FIG. 15 (A) are read and then "drug E" is read as the name of the contained medicine (Yes side of S3), the prescription D2 is "". Since "chemical E" is contained (Yes side of S4), the process proceeds to step S5. Then, in step S5, the drug E contained in the prescription information corresponding to the prescription D2 is automatically selected as the weighing target (S5), and the prescription amount of the drug E recorded in the prescription D2 is the weighing screen. It is displayed on 41 (S6).

Here, it is conceivable that the name of the contained drug corresponds to the name of the prescription drug included in the plurality of prescription information. Therefore, in such a case, the control unit 11 may allow the user to arbitrarily select any prescription information.

Here, FIG. 15B shows another example of the prescription information read from the plurality of prescriptions D1 to D3. The prescription D1 contains drugs A to C, the prescription D2 contains drugs D to F, and the prescription D3 contains drugs E, H, and I, respectively. That is, the drug E is contained in each of the prescriptions D2 and D3.

In this case, when the read name of the contained drug is "medicine E", the drug E is contained in both the prescription D2 and the prescription D3, so that the control unit 11 controls the prescription D2. Alternatively, the prescription selection screen 61 for selecting any of the prescription D3 is displayed on the touch panel 13. Here, FIG. 15C shows an example of the prescription selection screen 61.

Then, the control unit 11 selects the "medicine E" of the prescription D2 or the prescription D3 selected on the prescription selection screen 61 as a weighing target (S5), and the prescription amount of the drug E recorded in the prescription. Is displayed on the weighing screen 41 (S6).

According to such a prescription batch reading mode, after a plurality of prescriptions are continuously read by the barcode reader 17, the weighing of each drug recorded on the prescription can be continuously advanced, and the user can continuously read the prescriptions. Dispensing efficiency can be increased.

By the way, when one patient is examined by a plurality of clinical departments, the medicine may be weighed according to a plurality of prescriptions prescribed for each clinical department. Also in this case, as described above, a configuration in which prescription information is continuously read from a plurality of prescriptions is preferable. As a result, after the barcode reader 17 reads a plurality of prescriptions in succession, the weighing of each drug recorded in the prescription can be continuously advanced, and the dispensing efficiency of the user can be improved. .. At this time, when a plurality of prescriptions of the same patient are read, the control unit 11 displays a pop-up screen for arbitrarily selecting whether or not to integrate the prescriptions as one prescription information on the touch panel 13. It is conceivable to display it on. Then, when it is selected to integrate the plurality of prescriptions into one prescription information according to the pop-up screen, the control unit 11 generates one prescription information from the plurality of prescription information read from the plurality of prescriptions. After that, weighing in the drug weighing device 10 is performed according to the generated prescription information after integration.

Further, the control unit 11 can acquire all the prescription drug names recorded in each of the prescriptions by continuously reading a plurality of prescriptions of the same patient. Therefore, when a plurality of prescriptions of the same patient are read, the control unit 11 has a drug that is prohibited in advance to be taken at the same time among all the prescription drug names recorded in each of the prescriptions. It is conceivable to judge the presence or absence of. For example, the drugs prohibited to be taken at the same time are predetermined as a plurality of drugs that cause a change in formulation or side effects. At this time, the control unit 11 performs the simultaneous administration stored in the data storage unit 15 to audit whether or not the plurality of drugs contained in each of the prescription information are prohibited from being taken at the same time. Perform based on prohibited information. Then, when there is a drug for which it is prohibited to take at the same time among all the prescription drug names recorded in each of the prescriptions, the control unit 11 displays a warning to that effect on the touch panel 13 or the like. Can be considered. The control unit 11 displays the warning by characters, images, voice, or light. This makes it possible to prevent the prescription of a plurality of drugs that cause a change in formulation or side effects when taken at the same time at the drug weighing stage in the drug weighing device 10.

[Other embodiments]
Hereinafter, the chemical weighing system 2 according to another embodiment of the present invention will be described. The same components as those of the chemical weighing system 1 are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIG. 17, the drug weighing system 2 includes one or a plurality of the drug weighing devices 10, one or a plurality of the drug packaging devices 20, and a host system 70 connected to each of the drug weighing devices 10. To prepare for. In the chemical weighing system 2, the chemical weighing device 10, the chemical packaging device 20, and the higher-level system 70 are each communicably connected via a network N such as a LAN or the Internet.

The control unit 11 of the chemical weighing device 10 includes a CPU 111, an SD card 112, and a RAM 113. The SD card 112 is a storage means for storing various programs such as the kernel 114 executed by the CPU 111, the OS 115, and the scale single application 116. Instead of the SD card 112, a storage means such as a ROM in which the various programs are stored may be provided. The kernel 114 is a software program such as Linux®, and the OS 115 is an operating system such as Android® or iOS®. Further, the scale unit application is a software program for operating the chemical weighing device 10 as a normal electronic balance. That is, in the drug weighing device 10, the control unit 11 built in the drug weighing device 10 executes various processes such as the drug weighing process (see FIG. 5) executed by the drug weighing device 10. The program and database for doing this are not stored. Therefore, in the chemical weighing device 10, the stability of the function as an electronic balance is ensured.

On the other hand, the data storage unit 15 that can be attached to and detached from the USB port 16 is a USB memory that stores a log 151, a setting file 152, a form layout file 153, a chemical weighing program 154, a database 155, a database dump file 156, and the like. .. The log 151 is log data showing a history of operations of the chemical weighing device 10. It is also conceivable that a card slot is provided in place of the USB port 16 and the data storage unit 15 is a recording medium such as an SD card.

The setting file 152 and the form layout file 153 are data including setting contents of various processes executed by the control unit 11, print forms, and the like. The drug weighing program 154 is a software program for causing the control unit 11 to execute various processes such as the drug weighing process (see FIG. 5). The database 155 stores various master data, prescription information, weighing results, and the like used in the drug weighing process and the like in a database format. The database dump file 156 is a backup file output from the database 155 in the startup process (see FIG. 39) described later. The database dump file 156 is used to restore the data at the time of backup when an abnormality occurs in a part or all of various data stored in the database 156.

On the other hand, the chemical packaging device 20 includes a data storage unit 26 such as a hard disk or SSD, and a printing unit 27 that prints information on a packaging paper used for packaging chemicals in the packaging unit 22. The data storage unit 26 is provided with a shared folder that can be accessed from each of the drug weighing devices 10 via the network N. As a result, in each of the drug weighing devices 10, the control unit 11 displays the prescription information, the weighing result, and the tray number described later assigned to the dispensing sheet 30 in the shared folder of the data storage unit 26. It is possible to store information. At this time, the control unit 11 stores the prescription information and the weighing result in the data storage unit 26 in association with the tray number. As a result, the control unit 21 reads the tray number from the RFID tag 31 of the drug sheet 30, for example, and stores the prescription information and the weighing result corresponding to the drug sheet 30 based on the tray number. It can be read from the unit 26.

The host system 70 is, for example, an electronic medical record system, a dispensing support system, or the like, and is an information processing device such as a personal computer that inputs and manages the prescription information regarding a prescription drug to be prescribed to a patient. Specifically, the host system 70 includes a control unit 71, a data storage unit 72, and the like. The control unit 71 includes a CPU, RAM, ROM, and the like, and controls the host system 70 in an integrated manner. Further, the data storage unit 72 is a non-volatile storage means such as a hard disk or SSD that stores a program for causing the control unit 71 to execute various processes and the prescription information.

In the host system 70, the control unit 71 can transmit the prescription information stored in the data storage unit 72 to the drug weighing device 10 in response to a transmission request from the drug weighing device 10. .. At this time, the control unit 71 locks the prescription information selected as the weighing target by any of the drug weighing devices 10, and performs exclusive processing so that the same prescription information is not selected by the other drug weighing device. To execute. This prevents duplication of weighing work based on the drug weighing information using the plurality of drug weighing devices 10. The control unit 71 can also transmit the prescription information to the drug packaging device 20 in response to a transmission request from the drug packaging device 20. It is also possible for the control unit 71 to actively transmit the prescription information to the drug weighing device 10 or the drug packaging device 20.

In the drug weighing system 2, the drug weighing device 10 reads the prescription information from the prescription by the barcode reader 17, and in addition to the operation of inputting the prescription information to the touch panel 13, the prescription from the host system 70. It is possible to get information. Then, when the prescription information is acquired from the higher-level system 70, the control unit 11 stores the prescription information in the data storage unit 15. As a result, the control unit 11 can read out the prescription information arbitrarily selected from the data storage unit 15 in response to a user operation on the touch panel 13. Further, as will be described later, the control unit 11 can automatically read the prescription information from the data storage unit 15 in chronological order. Further, the control unit 11 can access the data storage unit 72 of the higher-level system 70 via the network N, read the prescription information, and copy it to the data storage unit 15.

[Prescription input processing]
In the drug weighing device 10, when the control unit 11 reads the prescription information from the prescription by the barcode reader 17, or when the prescription information stored in the data storage unit 15 is read out. Perform prescription input processing. For example, the prescription input process is a process executed between the step S1 and the step S2 in the drug weighing process. The prescription input process described here may be executed by the drug weighing device 10 in a configuration in which the drug weighing device 10 is not connected to the higher-level system 70, for example, the drug weighing system 1.

Hereinafter, an example of the procedure for the prescription input processing will be described with reference to FIG.

<Step S41>
In step S41, the control unit 11 determines whether or not the prescription information is within the expiration date according to the expiration date information included in the prescription information. Here, if the expiration date has been exceeded (No side of S41), the control unit 11 shifts the process to step S411. Then, in step S411, the control unit 11 displays on the touch panel 13 that the expiration date has expired and notifies the user, and then the prescription input process without subjecting the prescription information to the weighing target. To end. On the other hand, when the control unit 11 determines that it is within the expiration date (Yes side of S41), the process shifts to step S42.

<Steps S42 to S43>
In steps S42 to S43, the control unit 11 analyzes the usage information and drug information of one or more recipes contained in the prescription information, and acquires information such as the usage and prescription drug of each of the recipes. The recipe means a prescription for a unit to be taken, and is abbreviated as "Rp" at the time of display or printing in the drug weighing system 2. Hereinafter, the information of each of the recipes included in the prescription information is referred to as recipe information.

<Step S44>
In step S44, the control unit 11 determines whether or not an uneven record exists in the recipe included in the prescription information. The uneven record is a recipe in which the prescribed amount of a prescription drug differs depending on the time of administration. For example, for the drug A, a recipe in which the prescribed amount of each of the morning, noon, and evening doses is 1 mg, 1 mg, and 2 mg corresponds to the uneven record. Here, when the control unit 11 determines that the uneven record exists (Yes side of S44), the process shifts to step S45, and determines that the uneven record does not exist (No side of S44). The process shifts to step S46.

<Step S45>
In step S45, the control unit 11 executes a recipe division process for dividing a recipe containing the uneven record among the recipes included in the prescription information into recipes for each dosing time. Here, FIG. 19 shows an example of the recipe Rp1 which is an example of the uneven record, and an example of the recipes Rp11 to Rp13 after the recipe division processing. As shown in FIG. 19, in the recipe Rp1, the prescription amount of "A drug" in the morning, noon, and evening is different from the prescription amount in the morning and noon. Therefore, as shown in FIG. 19, the control unit 11 divides the recipe Rp1 into a recipe Rp11 corresponding only to the morning, a recipe Rp12 corresponding only to the daytime, and a recipe Rp13 corresponding only to the evening. When the daily amount of morning and noon is the same and only the daily amount of evening is different, it is conceivable to divide only the evening to generate the recipe. That is, it is conceivable that the control unit 11 divides only the dosing timings having different prescription amounts into different recipes among the plurality of dosing timings. Further, whether or not the recipe division process is executed in step S45 can be changed by the control unit 11 according to the user operation on the touch panel 13 in the initial setting of the chemical weighing device 10.

<Step S46>
In step S46, the control unit 11 determines whether or not there are a plurality of recipes having the same usage and number of days in the prescription information. For example, when there is a recipe indicating that A drug is prescribed for 7 days in the morning and noon and a recipe indicating that B drug is prescribed for 7 days in the morning and noon, the usage and the prescription information are used. It is determined that there are multiple recipes with the same number of days. Here, when the control unit 11 determines that there are a plurality of recipes having the same usage and the number of days (Yes side of S46), the process shifts to step S47 and determines that the recipes having the same usage and the number of days do not exist. (No side of S46), the process is shifted to step S48.

<Step S47>
In step S47, the control unit 11 executes a recipe summarization process for summarizing a plurality of recipes having the same usage and number of days in the prescription information into one recipe. Here, FIG. 20 shows an example of the recipes Rp21 to Rp23 before being summarized, and the recipes Rp2 and Rp23 after the recipe summarization process. As shown in FIG. 20, among the recipes Rp21 to Rp23, the recipe Rp21 and the recipe Rp22 have the same usage (minute 2) and number of days (7 days). Therefore, as shown in FIG. 20, the control unit 11 combines the recipe Rp21 and the recipe Rp22 into one recipe Rp2. As a result, a plurality of prescription drugs can be packaged in the packaging process of the drug packaging device 20 performed based on the prescription information after being collected by the drug weighing device 10. Further, whether or not the recipe summarization process is executed in step S47 can be changed by the control unit 11 according to the user operation on the touch panel 13 in the initial setting of the drug weighing device 10.

<Step S48>
Then, in step S48, the control unit 11 stores the prescription information after the recipe division process in the step S45 or the recipe summarization process in the step S47 in the data storage unit 15, and stores the prescription information in the data storage unit 15. It is stored in the shared folder of the data storage unit 26 of the chemical packaging device 20. This makes it possible for the drug packaging device 20 to read the prescription information and execute the packaging process.

[Display control processing]
Further, in the chemical weighing device 10, the control unit 11 executes a display control process for controlling the screen display of the touch panel 13 according to a preset type of system interlocking of the chemical weighing device 10. Specifically, in the chemical weighing device 10, the system interlocking selection screen P21 for selecting the type of the system interlocking is displayed on the touch panel 13 by the control unit 11 in the initial setting or the like. Here, FIG. 21 is a diagram showing an example of the system interlocking selection screen P21. As shown in FIG. 21, on the system interlocking selection screen P21, the types of the system interlocking are "sequential", "patient ID", "voucher number", "unprocessed", "processed", and "single unit". Multiple touch keys corresponding to are displayed. Then, the control unit 11 sets the type of system interlocking according to the user operation for the touch key of the touch panel 13. When the system interlocking type of the drug weighing device 10 is set to "single unit", the control unit 11 sets the drug weighing device 10 so that it can be used as an electronic balance and inputs the prescription information. Will not be accepted.

Hereinafter, an example of the procedure of the display control process will be described with reference to FIG. 22.

<Step S51>
In step S51, the control unit 11 determines whether or not the system interlocking type of the chemical weighing device 10 is set to "sequential". In addition, "sequential" is an operation mode in which the control unit 11 sequentially displays the recipes of the prescription information acquired from the higher-level system 70 on the touch panel 13. Here, if the system interlocking type is "sequential" (Yes side of S51), the control unit 11 shifts the process to step S52, and if it is not "sequential" (No side of S51), The process shifts to step S53.

<Step S52>
In step S52, the control unit 11 causes the touch panel 13 to display a prescription screen P23 for displaying the recipe information to be weighed by the drug weighing device 10. Here, FIGS. 23 and 24 are views showing an example of the prescription screen P23. As shown in FIG. 23, the prescription screen P23 includes a prescription information area A231 in which the dispenser of the recipe information, the prescription number, the number of days, the number of minutes, the age, the weight, and the like are displayed. The control unit 11 can also directly input the recipe information according to the user operation for each display location of the prescription information area A231.

Further, as shown in FIG. 23, the prescription screen P23 includes a drug display area A232 in which the daily amount and the total amount of each prescription drug to be weighed are displayed. Further, the control unit 11 alternately switches the display contents of the daily amount and the total amount for each prescription drug between the actually measured amount and the target amount in response to the user's touch operation on the drug display area A232. The measured amount is a value actually measured by the drug weighing device 10, and the target amount is a value determined as a prescription amount in the recipe information. The menu key K233 is displayed on the prescription screen P23, and the control unit 11 is an initial setting for starting the setting such as the system interlocking type according to the user operation of the menu key K233. Display the menu screen.

Further, as shown in FIG. 23, the prescription screen P23 includes a development region A234. When the user performs a touch operation or an upward flick operation on the expansion area A234, the control unit 11 expands the display area of the expansion area A234 as shown in FIG. 24. Then, in the expansion area A234, various touch keys indicating the contents that can be operated on the prescription screen P23 are displayed. For example, in the unfolding area A234, a setting key K235 for setting the type of packing paper used in the packing operation in the chemical packaging device 20 is displayed. The control unit 11 displays a setting screen for setting the type of the sachet according to the user operation of the setting key K235. The control unit 11 records the type of the packaging paper input on the setting screen as the prescription information referred to during the packaging operation in the drug packaging device 20. For example, the type of the packaging paper is distinguished by the material and length of the packaging paper, and a plurality of combinations for selecting the material and length of the packaging paper are displayed on the setting screen.

<Step S53>
In step S53, the control unit 11 determines whether or not the system interlocking type of the chemical weighing device 10 is set to "unprocessed" or "processed". In addition, "unprocessed" is an operation mode in which the control unit 11 displays only the prescription information for which weighing has not been completed by the drug weighing device 10. Further, "processed" is an operation mode in which the control unit 11 displays only the prescription information for which weighing has been completed by the drug weighing device 10. Here, when the system interlocking type is "unprocessed" or "processed" (Yes side of S53), the control unit 11 shifts the process to step S54 and shifts the process to "unprocessed" or "processed". If it is not "completed" (No side of S53), the process proceeds to step S56.

<Step S54>
In step S54, the control unit 11 determines whether the prescription unit or the recipe unit is selected as the display format when selecting the weighing target in the initial setting in the drug weighing device 10. Here, when the control unit 11 determines that the prescription unit is selected, it shifts the process to step S551 (Yes side of S54), and determines that the recipe unit is selected (No. of S54). Side), the process is shifted to step S552.

<Step S551>
In step S551, the control unit 11 causes the touch panel 13 to display a prescription list screen P25 including a list of the prescription information. Specifically, on the prescription list screen P25, when the type of the system interlocking is "unprocessed", a list of the prescription information that has not been weighed by the drug weighing device 10 is displayed. Further, when the type of the system interlocking is "processed", a list of the prescription information for which weighing by the drug weighing device 10 is completed is displayed on the prescription list screen P25. Here, FIGS. 25 and 26 are views showing an example of the prescription list screen P25. As shown in FIG. 25, on the prescription list screen P25, items such as a patient ID, a patient name, a clinical department, a number of recipes (Rp number), a drug name, and deletion corresponding to the prescription information are displayed. ..

Further, as shown in FIG. 25, the expansion area A251 is displayed on the prescription list screen P25. When the user performs a touch operation or an upward flick operation on the expansion area A251, the control unit 11 expands the display area of the expansion area A251 as shown in FIG. 26. Then, in the expansion area A251, various touch keys indicating the contents that can be operated on the prescription list screen P25 are displayed.

By the way, when displaying the prescription list screen P25, the control unit 11 requests the higher-level system 70 to transmit a predetermined number of preset prescription information that can be simultaneously displayed on the prescription list screen P25. Then, the control unit 11 receives the predetermined number of the prescription information from the host system 70 and stores it in the data storage unit 15. In this case, the control unit 11 switches the content of the prescription information displayed on the prescription list screen P25 according to the operation of the "previous data" or the "next data" displayed in the expansion area A251. Specifically, the control unit 11 sends a predetermined number of prescription information prior to the currently displayed prescription information in response to the operation of the "prescription data" displayed in the expansion area A251. Request to system 70. Similarly, the control unit 11 transmits a predetermined number of the prescription information after the currently displayed prescription information in response to the operation of the "next data" displayed in the expansion area A251. Request to. As a result, the control unit 11 stores the predetermined number of the prescription information transmitted from the higher-level system 70 in the data storage unit 15 and displays it on the prescription list screen P25. As described above, if the drug weighing device 10 is configured to acquire only the necessary prescription information from the host system 70, the prescription is configured in a configuration in which a plurality of drug weighing devices 10 are connected to the host system 70. Information exclusive processing can be realized. Specifically, as described above, in the higher-level system 70, the control unit 71 locks the prescription information selected as the weighing target in one drug weighing device 10, and the other drug weighing device 10 is used. It is conceivable to control not to send to.

On the other hand, it is also conceivable that the drug weighing device 10 acquires the prescription information from the higher-level system 70 according to, for example, the dispensing system prescription IF sharing specification (NSIPS). Further, the prescription information may be transmitted from the higher-level system 70 to the drug packaging device 20 and then transmitted from the drug packaging device 20 to the drug weighing device 10. Then, the control unit 11 stores the prescription information acquired from the higher-level system 70 or the drug packaging device 20 in the data storage unit 15. In this case, the data storage unit 15 can store not only the predetermined number of prescriptions that can be displayed on the prescription list screen P25 but also a large number of prescription information. Therefore, the control unit 11 can slide and change the prescription information displayed on the prescription list screen P25 in response to a user's vertical flick operation on the prescription list screen P25. In this case, the "previous data" and the "next data" are not displayed in the expansion area A251. Of course, the control unit 11 requests the higher-level system 70 to transmit more prescription information than the predetermined number that can be displayed on the prescription list screen P25, receives the prescription information, and receives the prescription information, and the prescription list screen P25. It is also conceivable that the prescription information can be displayed as a slide in response to a flick operation in the vertical direction in the above.

Then, when the display position corresponding to any of the prescription information is operated on the prescription list screen P25, the control unit 11 changes the display color of the display position corresponding to the prescription information and is in the selected state. Indicates that. After that, when the user performs a right-handed or left-handed flick operation on the touch panel 13 with any of the prescription information selected, the control unit 11 displays the details of the selected prescription information. The prescription drug information screen P27 shown is displayed on the touch panel 13. Here, FIG. 27 is a diagram showing an example of the prescription drug information screen P27. On the prescription drug information screen P27, information on prescription drugs (drug name, usage, number of days, prescription amount, etc.) is displayed for each recipe included in the prescription information.

Here, when the display position corresponding to any of the recipes is operated on the prescription drug information screen P27, the control unit 11 changes the display color of the display position corresponding to the recipe and is in the selected state. Is shown. After that, when the control unit 11 operates the enter key displayed after the user has performed a touch operation or an upward flick operation on the expansion area A271 of the prescription drug information screen P27, the selection key is being selected. Is determined as a weighing target, and the prescription screen P23 is displayed. In the prescription drug information screen P27, the control unit 11 changes the display position of the prescription drug or recipe for which weighing has already been completed to a display color different from the display color indicating that the product is being selected. Show that.

<Step S552>
On the other hand, in step S552, the control unit 11 causes the touch panel 13 to display a recipe list screen P28 including a list of recipe information obtained by decomposing the prescription information for each recipe. Specifically, on the recipe list screen P28, when the type of the system interlocking is "unprocessed", a list of the recipe information for which weighing has not been completed by the drug weighing device 10 is displayed. When the system interlocking type is "processed", a list of the recipe information for which weighing has been completed by the drug weighing device 10 is displayed on the recipe list screen P28. Here, FIGS. 28 and 29 are diagrams showing an example of the recipe list screen P28. As shown in FIG. 28, items such as a patient ID, a patient name, a clinical department, a drug name, and deletion corresponding to the recipe information are displayed on the recipe list screen P28.

Further, as shown in FIG. 28, the development area A281 is displayed on the recipe list screen P28. When the user performs a touch operation or an upward flick operation on the expansion area A281, the control unit 11 expands the display area of the expansion area A281 as shown in FIG. 29. Then, in the expansion area A281, various touch keys indicating the contents that can be operated on the recipe list screen P28 are displayed.

By the way, even when the recipe list screen P28 is displayed, the control unit 11 has a predetermined number of presets that can be simultaneously displayed on the recipe list screen P28, as in the case of displaying the prescription list screen P25. The higher system 70 is requested to transmit the recipe information. Then, the control unit 11 receives the predetermined number of the recipe information from the host system 70 and stores it in the data storage unit 15. Also in this case, the control unit 11 switches the content of the recipe information displayed on the recipe list screen P28 in response to the operation of the "previous data" or the "next data" displayed in the expansion area A251. In this way, in order for the drug weighing device 10 to acquire only the necessary recipe information from the host system 70, the host system 70 is configured in a configuration in which a plurality of the drug weighing devices 10 are connected to the host system 70. Can execute the exclusive processing of the recipe information or the prescription information.

Further, in a configuration in which the drug weighing device 10 acquires the recipe information from the higher-level system 70 according to, for example, the dispensing system prescription IF sharing specification (NSIPS), the control unit 11 moves the user up and down with respect to the recipe list screen P28. It is possible to slide and change the recipe information displayed on the recipe list screen P28 according to the flick operation in the direction.

Then, when the display position corresponding to any of the recipe information is operated on the recipe list screen P28, the control unit 11 changes the display color of the display position corresponding to the recipe information and is in the selected state. Indicates that. After that, when the user performs a right-handed or left-handed flick operation on the touch panel 13 with any of the recipe information selected, the control unit 11 displays the details of the selected recipe information. The prescription drug information screen P30 shown is displayed on the touch panel 13. Here, FIG. 30 is a diagram showing an example of the prescription drug information screen P30. On the prescription drug information screen P30, information on prescription drugs (drug name, usage, number of days, prescription amount, etc.) included in the recipe information is displayed.

After that, the control unit 11 is displayed after the user has performed a touch operation or an upward flick operation on the expansion area A281 of the recipe list screen P28 or the expansion area A301 of the prescription drug information screen P30. When the enter key is operated, the selected recipe information is determined as a weighing target, and the prescription screen P23 is displayed. In the prescription drug information screen P30, the control unit 11 indicates that by changing the display position of the prescription drug for which weighing has already been completed to a different display color.

<Step S56>
Further, in step S56, the control unit 11 determines whether or not the system interlocking type of the drug weighing device 10 is set to "patient ID" or "voucher number". The "patient ID" is an operation mode in which the control unit 11 reads out the prescription information corresponding to the patient ID input by the user operation on the touch panel 13 from the data storage unit 15 or the host system 70. Further, the "voucher number" is an operation mode in which the control unit 11 reads out the prescription information corresponding to the voucher number input by the user operation on the touch panel 13 from the data storage unit 15 or the host system 70. .. Here, when the system interlocking type is "patient ID" or "voucher number" (Yes side of S56), the control unit 11 shifts the process to step S57, and shifts the process to "patient ID" and "patient ID". If it is not "voucher number" (No side of S57), the process returns to step S51.

<Step S57>
In step S57, the control unit 11 inputs the patient ID when the system interlocking type is "patient ID", and the voucher number when the system interlocking type is "voucher number". The input screen P31 for this purpose is displayed on the touch panel 13. Here, FIG. 31 is a diagram showing an example of the input screen P31 for inputting the patient ID. When the patient ID is input to the input screen P31 shown in FIG. 31, the control unit 11 extracts the prescription information corresponding to the patient ID from the prescription information stored in the data storage unit 15. Then, the control unit 11 displays the prescription information corresponding to the patient ID on the prescription list screen P25. When the type of system interlocking is "voucher number", an input unit for inputting the voucher number is displayed on the input screen P31, and the voucher number input to the input unit is displayed. The corresponding prescription information is read out.

[Generic drug use processing]
Further, in the drug weighing device 10, as described in steps S15 to S21 of the drug weighing process (see FIG. 5), a generic drug for using a generic drug in place of the prescription drug included in the prescription information. The usage process is executed. That is, the generic drug use process described below is a process executed in place of the process after step S15 executed on the No side of step S13 in the drug weighing process (see FIG. 5).

Hereinafter, another example of the generic drug use treatment will be described with reference to FIG. 32. It is also conceivable that the generic drug use process described here may be executed by the drug weighing device 10 in a configuration in which the drug weighing device 10 is not connected to the higher-level system 70, for example, in the drug weighing system 1. .. Further, here, as shown in FIG. 33, the prescription information displayed on the prescription screen P23 contains a prescription drug of "Gaster powder 10%", and the bar code reader 17 includes "Gas dog powder 10". The case where "%" is read as the name of the contained medicine will be described as an example.

<Step S61>
First, in step S61, the control unit 11 executes a process for selecting the change target to be changed to the contained drug name read in step S3 from the prescription drug names included in the prescription information. Specifically, the control unit 11 displays a selection screen for selecting a change target from the prescription drug names included in the prescription information, and selects the prescription drug name by user operation on the touch panel 13. Select as the change target. When the prescription drug name is one, the control unit 11 may automatically select the one prescription drug name as a change target.

<Step S62>
Next, in step S62, whether or not the prescription information includes non-changeable information indicating that the prescription drug name selected in step S61 cannot be changed to a generic drug. To judge. Then, when the prescription information includes the unchangeable information (Yes side of S62), the control unit 11 shifts the process to step S63. On the other hand, when the non-changeable information is not included (No side of S62), the control unit 11 shifts the process to step S611 and executes the change process of the prescription drug described later (see FIG. 34). The non-changeable information is added to the prescription information in the higher-level system 70. It is also conceivable that the control unit 11 may be added to the touch panel 13 in response to a user operation.

<Step S63>
In step S63, the control unit 11 displays on the touch panel 13 that it is prohibited to change the prescription drug to a generic drug, notifies the user, and shifts the process to step S64. That is, the prescription drug is not changed to the generic drug corresponding to the contained drug name.

<Step S64>
In step S64, the control unit 11 determines whether or not the prescription information includes another prescription drug name that has not yet been selected in step S61. Here, when the control unit 11 determines that the unselected other prescription drug is contained (Yes side of S64), the process shifts to the step S61, and the unselected other prescription drug is added. If it is determined that it is not included (No side of S64), the generic drug use process is terminated.

[Change processing of generic drugs]
Next, with reference to FIG. 34, an example of the procedure for changing the prescription drug executed in step S611 will be described.

<Step S71>
In step S71, the control unit 11 determines whether or not the name of the contained drug read from the drug bottle by the barcode reader 17 is registered as a generic drug of the prescription drug in the generic drug master. Here, when the control unit 11 determines that the name of the contained drug is registered as the generic drug (Yes side of S71), the process shifts to step S72. On the other hand, when the contained drug name is not registered as the generic drug (No side of S71), the control unit 11 shifts the process to step S711 and registers the generic drug described later (see FIG. 37). To execute.

<Step S72>
In step S72, the control unit 11 changes the prescription drug selected in step S61 to the generic drug read as the contained drug name, redisplays the prescription screen P23, and changes the prescription drug. End the process. Here, FIG. 35 is a diagram showing an example of the prescription screen P23 after the prescription drug has been changed to the generic drug. As shown in FIG. 35, on the prescription screen P23 displayed in step S72, "Gaster powder 10%" contained as a prescription drug in the prescription information is replaced with "Gas dog powder 10%" which is a generic drug name. Has been changed to. When the prescription drug is changed to the generic drug in this way, the control unit 11 provides history information of the change (for example, the date and time of the change, the name of the pharmacist in charge of the change, the content of the change, etc.). It is conceivable that it will be recorded as the result of the weighing. This makes it possible to easily confirm the history of changing the prescription drug to the generic drug or the like later.

Further, in step S72, the control unit 11 may display the drug list screen P33 of the original drug and the generic drug corresponding to the contained drug name on the touch panel 13 based on the generic drug master. Can be considered as an embodiment of. Here, FIG. 36 is a diagram showing an example of the drug list screen P33. As shown in FIG. 36, the drug list screen P33 displays the generic name (famotidine) of the drug corresponding to the contained drug name, and the original drug and the generic drug corresponding to the contained drug name. When the user performs a touch operation for selecting either the original drug or the generic drug being displayed on the drug list screen P33, the display color of the display position of the selected drug name is changed. The selection status is shown. At the time of initial display of the medicine list screen P33, the stored medicine name read by the barcode reader 17 is selected. Then, when the determination key K331 is operated with any one of the generic drugs selected, the control unit 11 changes the prescription drug to the generic drug selected on the drug list screen P33. When the cancel key K332 on the drug list screen P33 is operated, the control unit 11 cancels the registration of the generic drug and ends the change process of the prescription drug.

[Registration process for generic drugs]
Next, with reference to FIG. 37, an example of the procedure for the registration process of the generic drug executed in step S711 will be described.

<Step S81>
First, in step S81, the control unit 11 displays on the touch panel 13 that the name of the contained drug is not registered as the generic drug, and whether or not the name of the contained drug is registered as the generic drug. A confirmation message (see, for example, FIG. 9C) is displayed.

<Step S82>
Then, in step S82, when the control unit 11 determines that the operation to register the name of the contained drug as the generic drug has been performed on the touch panel 13 (Yes side of S82), the process is performed in step S83. Migrate. When the operation to not register the name of the contained drug as the generic drug is performed on the touch panel 13 (No side of S82), the control unit 11 ends the registration process of the generic drug.

<Step S83>
In step S83, the control unit 11 causes the touch panel 13 to display a maintenance screen P38 for registering the generic drug in the generic drug master. Specifically, when the prescription drug name selected in step S61 corresponds to the original drug name registered in the drug master, the control unit 11 associates the name of the original drug with the generic drug name. The maintenance screen P38 for registering a generic drug is displayed. On the other hand, when the prescription drug name selected in step S61 corresponds to the generic drug name registered in the generic drug master, the generic drug name corresponding to the generic drug name is used as the generic drug master. Identify based on. Then, the maintenance screen P38 for registering the generic drug name is displayed in association with the specified generic drug name.

Here, FIG. 38 is a diagram showing an example of the maintenance screen P38. As shown in FIG. 38, the maintenance screen P38 displays the name of the original drug and the registered generic drug corresponding to the original drug, and the name of the contained drug is added as the generic drug of the original drug. The status is displayed. For example, in the maintenance screen P38 shown in FIG. 38, when "Gasdog San 10%" is not registered as a generic drug of the original drug "Gaster San 10%", the "Gas Dog" is used as the name of the contained drug. A display example is shown when "San 10%" is read.

<Steps S84 to S85>
Then, in steps S84 to S85, the control unit 11 waits for the operation of the registration key K381 or the end key K382 on the maintenance screen P38 (No side of S84 and S85). Here, when the control unit 11 determines that the registration key K381 has been operated (Yes side of S84), the control unit 11 shifts the process to step S86. On the other hand, when the control unit 11 determines that the end key K382 has been operated (Yes side of S85), the control unit 11 ends the registration process of the generic drug without registering the contained drug as the generic drug.

<Step S86>
In step S86, the control unit 11 registers the prescription drug as the generic drug in the generic drug master, and sends a confirmation message for confirming whether or not to change to the generic drug registered on the maintenance screen P38. Display.

<Step S87>
Then, when the operation to change to the generic drug is performed (Yes side of S87), the control unit 11 shifts the process to step S88. In step S88, the control unit 11 causes the touch panel 13 to display the prescription screen P23 (see FIG. 35) after changing the prescription drug to the generic drug in the same manner as in step S72. On the other hand, when the operation of not changing to the generic drug is performed (No side of S87), the control unit 11 ends the registration process of the generic drug without changing the prescription drug to the generic drug.

[Start process]
Further, in the chemical weighing device 10, when the power of the chemical weighing device 10 is turned on and the chemical weighing device 10 is started, the activation process preset by the control unit 11 is executed. The start processing is executed by the control unit 11 when the chemical weighing device 10 returns from the power saving mode to the normal mode, or when the date updating process is executed in the chemical weighing device 10. Is also possible. Hereinafter, an example of the procedure of the activation process will be described with reference to FIG. 39.

<Step S91>
When the power of the chemical weighing device 10 is turned on and the chemical weighing device 10 is started, in step S91, the CPU 111 executes the kernel 114 and the OS 115 stored in the SD card 112 to control the control. The chemical weighing device 10 can be controlled by the unit 11.

<Steps S92 to S94>
In step 92, the control unit 11 confirms whether or not the data storage unit 15 is connected to the USB port 16. Then, when the connection of the data storage unit 15 is confirmed in step S93 (Yes side of S93), the control unit 11 shifts the process to step S931 and confirms the connection of the data storage unit 15. If not (No side of S93), the process is shifted to step S94. In step S94, the control unit 11 operates the drug weighing device 10 as an electronic balance by activating the scale unit application 116 in the SD card 112. After that, when the power OFF operation for the touch panel 13 is performed in step S95 (Yes side of S95), the control unit 11 executes a shutdown process of the chemical weighing device 10 in the following step S96 to turn on the power. Turn it off.

<Steps S931 to S932>
On the other hand, when the connection of the data storage unit 15 is confirmed, the control unit 11 activates the drug weighing program 154 (S932) after executing a preset update process in the following step S931 to perform the process. To step S95.

Specifically, in the update process, the control unit 11 determines whether or not the drug weighing program 154 stored in the data storage unit 15 is the latest. Whether or not the drug weighing program is up-to-date is determined, for example, by acquiring updated information from the Internet or the like via the host system 70 or the network N. Here, when it is determined that the drug weighing program 154 is not the latest, the control unit 11 downloads the latest drug weighing program 154 and updates the drug weighing program 154 of the data storage unit 15.

Then, the control unit 11 stores data such as the prescription information, the weighing result, the filling record, the amount of chemicals used, the incident history, and the error history, which have passed the preset deletion target period, in the data storage unit 15. Delete from database 155. The filling record is recorded as a history of weighing and filling in a medicine bottle by the medicine weighing device 10, and the filling amount for each medicine bottle is recorded as a history of medicines weighed by the medicine weighing device 10. The recorded amount of each drug used. Further, the incident history is information on an incident generated by the drug weighing device 10 or an incident input from the outside to the drug weighing device 10, and the error history is information on an error generated by the drug weighing device 10.

After that, the control unit 11 backs up various data such as the prescription information, the weighing result, various master information (generic drug master, etc.), and system setting information stored in the database 155 of the data storage unit 15. .. Specifically, the control unit 11 manages the database 155 using a well-known database management system such as SQLite (registered trademark), MySQL (registered trademark), or PostgreSQL (registered trademark) that uses the SQL language. .. Therefore, the control unit 11 uses the backup function of the database management system to store the table data such as the prescription information, the weighing result, various master information, and the system setting information stored in the database format into the database. It is output as a dump file 156 and stored in the data storage unit 15. At this time, when the update process is normally completed, the control unit 11 leaves only the latest database dump file 156 or only the preset number of the database dump files 156, and the previous database dump file. Delete 156. The backup destination by the control unit 11 is not limited to the data storage unit 15, but may be, for example, the drug packaging device 20, the host system 70, or a server device on the Internet. As described above, since the backup is executed at the time of starting up in the chemical weighing device 10, even if an abnormality occurs in the chemical weighing device 10 and the database is damaged after that, at least the chemical weighing device 10 is used. The database can be restored until the device 10 is started.

[Variation example of chemical weighing process]
Then, also in the chemical weighing system 2 configured in this way, in the chemical weighing device 10, the chemical weighing process similar to the chemical weighing process (see FIG. 5) is executed by the control unit 11. However, as described above, in the drug weighing system 2, the method of reading the prescription information in the step S1 executed by the drug weighing device 10 is different. Specifically, the control unit 11 can receive the prescription information from the higher-level system 70 in addition to reading the prescription information using the barcode reader 17. That is, in the step S1 of the drug weighing process, the control unit 11 receives from the higher-level system 70 and stores any of the prescription information in the data storage unit 15 in response to a user operation on the touch panel 13. Even when the prescription information is selected, it is determined that the prescription information has been input, and the process is shifted to the step S2. Further, when the system interlocking type is set to "sequential", the control unit 11 obtains the prescription information acquired from the higher-level system 70 and stored in the data storage unit 15 in chronological order. The process is also shifted to step S2 when the data is automatically read.

Here, in step S2, when the recipe to be weighed by the drug weighing device 10 is determined, the control unit 11 executes an automatic numbering process for setting a tray number corresponding to the recipe. The tray number is a 4-digit value automatically set by the control unit 11 in the chemical weighing device 10, and is preset in the chemical weighing system 2 so as not to be duplicated for each chemical weighing device 10. It is set within the range. For example, as shown in FIG. 17, when four chemical weighing devices 10 are connected to the chemical weighing system 2, "0000" to "1000" and "1001" to each of the chemical weighing devices 10 are connected. Tray numbers from "2000", "2001" to "3000", and "3001" to "4000" are assigned in advance. Further, the tray number is a number assigned to each of the recipes, and even if a plurality of prescription drugs are included in the recipe, they are numbered as a common number for each of the prescription drugs.

At this time, the control unit 11 confirms that the tray number does not match the tray number stored in the shared folder provided in the data storage unit 26 of each of the chemical packaging devices 20. Specifically, only the tray number for which the packaging process in the drug packaging device 20 has not been completed remains in the shared folder, and the tray number for which the packaging process has been completed is the drug packaging device 20. Is erased by the control unit 21 of the above. On the other hand, when the tray number is not stored in the shared folder, the control unit 11 of the chemical weighing device 10 stores the tray number in the shared folder of the chemical packaging device 20. Further, the control unit 11 adds the information corresponding to the tray number to the recipe information corresponding to the tray number set here among the prescription information stored in the data storage unit 25. As a result, the drug packaging device 20 can read the recipe information from the data storage unit 25 based on the tray number. The timing of recording the correspondence between the recipe information and the tray number in the data storage unit 25 by the control unit 11 is the timing at which the RFID reader / writer 14 records the tray number in the RFID tag 31. You may. Further, the timing at which the control unit 11 stores the recipe information in the data storage unit 25 may be after the recipe information is associated with the tray number.

On the other hand, when the tray number assigned to be assigned to the recipe is stored in the shared folder, the control unit 11 sets the number next to the tray number as the tray number corresponding to the recipe. do. That is, the control unit 11 assigns a tray number that is not stored in the shared folder to the recipe. This prevents the drug weighing device 10 from overlapping the tray number with other recipes for which the packaging process in the drug packaging device 20 has not been completed. When a plurality of the chemical packaging devices 20 are connected to the chemical weighing system 2, the shared folders may be provided in each of the chemical packaging devices 20. On the other hand, it is conceivable that the shared folder is provided only in any one of the chemical packaging devices 20, and the other chemical packaging devices 20 can refer to or delete the tray number of the shared folder.

Further, in step S2, the control unit 11 stores the tray number in the shared folder, and then which drug packaging device 20 executes the packaging process of the recipe corresponding to the tray number. The machine selection screen P40 for selecting is displayed on the touch panel 13. Here, FIG. 40 is a diagram showing an example of the unit selection screen P40. As shown in FIG. 40, the machine number selection key K401 for selecting a machine number preset for each of the chemical packaging devices 20 is displayed on the machine number selection screen P40. The control unit 11 displays a number of machine numbers preset in the pull-down menu in response to the operation of the machine selection key K401, and inputs the machine number selected in the pull-down menu to the machine selection key K401. It is considered that the number of machine numbers displayed in the pull-down menu is the number of the chemical packaging devices 20 connected to the chemical weighing system 2 or the maximum number that can be connected to the chemical weighing system 2. ..

Further, on the unit selection screen P40, a hopper selection key K402 for selecting a hopper to be used in the packaging process in the chemical packaging device 20 is displayed. The control unit 11 displays a hopper number preset in the pull-down menu in response to an operation of the hopper selection key K402, and inputs the hopper number selected in the pull-down menu to the hopper selection key K402. For example, in the pull-down menu, "A" indicating the hopper 25A provided in the chemical packaging device 20, "B" indicating the hopper 25B, or "AB" indicating that any of the hoppers 25A and 25B may be used. "Is considered to be displayed. The control unit 11 changes the display of the pull-down menu on the hopper selection key K402 according to the number of hoppers provided in the chemical packaging device 20 corresponding to the machine number selected by the machine selection key K401. It is also possible to do it.

In the machine selection screen P40, the machine selection key K401 and the hopper selection key K402 are displayed, and the case where the machine number and the hopper number are input at the same time is taken as an example, but the present invention is not limited to this. .. Specifically, in step S2, the control unit 11 displays a unit selection screen in which only the unit selection key K401 is displayed and causes the unit number to be input, and then weighs the prescription drug in the drug weighing device 10. At the completion of the work, it is conceivable to display the hopper selection screen in which only the hopper selection key K402 is displayed and to input the hopper number. This makes it possible to select the hopper for each of the prescription drugs when a plurality of prescription drugs are included in one recipe. In addition, the trouble of inputting the machine number for each prescription drug is omitted.

Then, in the process corresponding to the step S9 (see FIG. 5) of the chemical weighing process, the control unit 11 uses the RFID reader / writer 14 to convert the tray number, the machine number, and the hopper number into the RFID tag 31. Write to. As a result, when the dispensing sheet 30 provided with the RFID 31 is set in the chemical packaging device 20, the machine number stored in the RFID 31 by the control unit 21 in the chemical packaging device 20 is the chemical packaging. It is possible to collate whether or not it matches the machine number of the device 20. Further, in the chemical packaging device 20, the control unit 21 can automatically set the charging destination of the chemicals in the dispensing sheet 30 according to the hopper number. Then, in the medicine packaging device 20, the recipe information stored in the data storage unit 26 in association with the tray number is read out from the data storage unit 26 by the control unit 21. The machine number and the hopper number are stored in the shared folder of the data storage unit 26 in association with the tray number, and the control unit 21 moves from the shared folder to the machine number according to the tray number. And it is also conceivable to read the hopper number.

Further, in the drug weighing device 10, the control unit 11 can write the tray number, the machine number, and the hopper number to the RFID tag 31 in recipe units instead of prescription drug units. .. In this case, the control unit 11 shifts the "registration" key on the prescription screen P23 (see FIG. 23) to an operable state when all the weighing of the plurality of prescription drugs contained in one recipe is completed. , "Please set the medicine tray" is displayed on the touch panel 13. Then, when the "registration" key is operated on the prescription screen P23, the control unit 11 converts the tray number, the machine number, and the hopper number corresponding to the recipe into the RFID tag by the RFID reader / writer 14. Write to 31.

[Package input processing]
On the other hand, in the drug packaging device 20, the control unit 21 reads the tray number from the RFID tag 31 of the drug sheet 30, and the recipe information corresponding to the tray number and the weighing result are data to be packaged. The sachet input process to be input as is executed.

Here, the recipe information includes a prescription date, a tray number, a prescription number, a data unit, a drug detail number, a drug code, a patient ID, a voucher number, a machine number, a hopper information, a state classification, and the like. The drug specification number is information for specifying the weighing result or the like corresponding to the recipe information. The hopper information is information indicating a hopper used in the chemical packaging device 20, for example, "A" when the hopper 25A is selected, "B" when the hopper 25B is selected, and the above. When it is selected that either the hopper 25A or the hopper 25B may be used, it is represented by "AB".

In the package input process, the control unit 21 reads the recipe information corresponding to the tray number from the data storage unit 26 based on the tray number read from the RFID tag 31 by the RFID reader / writer 24. Then, the control unit 21 displays the recipe information on the package input screen P41 displayed on the touch panel 23. Here, FIGS. 41 and 42 are views showing an example of the package input screen P41.

As shown in FIG. 41, the package input screen P41 includes a display area A411 in which information such as the number of prescription drugs included in the recipe information is displayed. Further, the package input screen P41 is a list of prescription drugs already read from the RFID tag 31 by the RFID reader / writer 24 among the prescription drugs included in the recipe information, the weighing result of each of the prescription drugs, and the above. Includes a display area A412 on which the packaging pattern, the hopper number, and the like are displayed. As a result, the user can easily grasp the number of chemicals currently insufficient for starting the packaging operation of the recipe in the chemical packaging device 20. In addition, by comparing the prescription with the list of prescription drugs displayed on the packaging input screen P41, it is possible to grasp the names of the drugs currently lacking in order to start the packaging operation of the recipe information. be. Then, as shown in FIG. 42, when all the prescription drugs included in the recipe information displayed on the packaging input screen P42 are read, the control unit 21 starts the issuing key for starting the packaging operation. Change K413 to an operable state. After that, the control unit 21 starts the packaging operation for the recipe information in response to the operation of the issuing key K413.

Further, when the control unit 21 reads the tray number from the RFID tag 31 by the RFID reader / writer 24, the list of prescription drugs included in the recipe information corresponding to the tray number is input in a package. It is also conceivable to display it on the screen P41. Then, the control unit 21 displays a character (“◯”” or “◯” indicating whether or not the information of each of the prescription drugs has been read from the RFID tag 31 in the list of the drug names displayed on the package input screen P41. It is conceivable to display confirmation information such as "x") or an image. As a result, the user can easily grasp the number of currently insufficient chemicals and the name of the chemical by checking the package input screen P41. The presence or absence of reading of each of the prescription drugs on the package input screen P41 may be indicated by, for example, changing the display color (presence or absence of gray out) of the display position of each of the prescription drugs.

By the way, it is conceivable that a plurality of the prescription drugs included in the recipe information are placed on one of the dispensing sheets 30, and the recipe units are charged into the hopper 25A or the hopper 25B. In this case, when the tray number is read from the RFID tag 31 of the dispensing sheet 30, the control unit 21 starts the packaging operation related to the recipe information without displaying the packaging input screen P41. Display the monitor screen for.

[Drug inspection printing process]
Further, in the chemical packaging device 20, the control unit 21 uses the printing unit 27 to execute a drug inspection printing process for printing and outputting the weighing result output from the chemical weighing device 10 on the packaging paper. It is conceivable to do.

Specifically, in the drug inspection printing process, the control unit 21 prints preset drug inspection information at the beginning or end of a series of packaging papers output by the packaging operation of the drug packaging device 20. Add the wrapping paper and output it. The content of the drug inspection information can be changed by the control unit 21 according to a user operation on the touch panel 23 in the initial setting of the drug packaging device 20 or the like.

Here, FIGS. 43 and 44 are views showing an example of a printed image of the drug detection information. The drug test information shown in FIG. 43 includes the date (November 26, 2007), patient name (Taro Yuyama), voucher number (5678), number of days (3), and total drug inclusion weight (369.0000 g). included. The total weight of the medicine included is the total value of the total weight of the packing paper used for the packaging of the recipe unit and the total weight of the prescription medicine included in the recipe information. For example, the control unit 21 adds up the total weight of the packaging paper included in the recipe information output from the drug weighing device 10 and the weighing result output from the drug weighing device 10. It is possible to calculate the total weight of the drug included. In the chemical weighing device 10, the control unit 11 multiplies the number of packaging papers used for packaging in the recipe unit by the preset weight per sheet of the packaging paper. It is calculated as the total weight of the packaging paper and recorded as one item of the recipe information. The control unit 11 determines the weight per sheet of the packaging paper, for example, by operating the previous stage setting key K235 (see FIG. 24) for setting the type of the packaging paper. It is possible to make a judgment according to the combination of material and length. By printing the drug inspection information on the packaging paper in this way, for example, the user can audit the packaging operation for each recipe without referring to the prescription. For example, the user separates the packaging paper on which the drug inspection information is printed from a series of packaging papers, and weighs the total weight of the remaining packaging paper with the drug weighing device 10 or another electronic balance. .. Then, the user performs an audit by comparing the total weight of the drug package printed as the drug test information with the actual weighed value.

In addition, the drug inspection information shown in FIG. 44 includes the drug name, the packaging pattern (11111111), the expiration date (November 26, 2007), the lot number, the measured value (369.0000 g), and the theoretical value (369.0000 g). ) Etc. are included. The sachet pattern is information for indicating the dosing time (morning, noon, evening, etc.) defined in the recipe information at the positions of "1" and "0" in the preset plurality of digits. The measured value is the total weight of the prescription chemicals actually weighed by the chemical weighing device 10, and is information included in the weighing result output from the chemical weighing device 10. The theoretical value is the theoretical total weight of the prescription drug calculated based on the daily dose, usage, number of days, etc. included in the recipe information. For example, the control unit 21 subtracts the weight of a prescription drug that is not to be taken within the dosing period from the maximum weight obtained by multiplying the daily dose by the number of doses determined by the usage and further multiplied by the number of days. By doing so, the theoretical value is calculated. Specifically, if the usage is set to three times, morning, noon, and evening, and the start time and end time of administration are both noon, the weight of the medicine for the morning of the first day and the last day The theoretical value is calculated by excluding the sum of the weight of the medicine for the evening and the weight of the medicine from the maximum weight. Even in such a case, the user can audit the recipe-based packaging using the drug weighing device 10 or another electronic balance while referring to the packaging paper on which the drug inspection information is printed. can.

[Outline of Embodiment]
The drug weighing device according to the present invention includes a weighing means, a prescription information reading means, a contained drug information reading means, and a control means. The weighing means weighs chemicals. The prescription information reading means reads prescription information including prescription drug identification information for identifying one or a plurality of prescription drugs recorded on the prescription from the prescription. The contained medicine information reading means reads the contained medicine information including the contained medicine identification information for identifying the contained medicine recorded in the medicine container from the medicine container. When the contained medicine read by the contained medicine information reading means corresponds to any of the prescribed medicines read by the prescription information reading means, the control means selects the prescription medicine as a weighing target. The display means displays the weighing screen on which the prescription drug is to be weighed. The prescription information includes, for example, prescription delivery date, patient ID, patient name, patient birth date, dosage form information (internal use, external use, etc.), drug information (drug code, drug name, dose), usage information (1). (3 times a day after every meal, etc.) etc.) are included. The prescription drug identification information and the contained drug identification information are information such as a drug name or a drug code that can specify the type of drug.

According to the present invention, when the contained medicine corresponds to any of the prescription medicines, the prescription medicine is automatically selected as a weighing target and displayed on the weighing screen. That is, according to the present invention, the user can collate the prescription drug and the contained drug in the drug weighing device only by having the contained drug information reading means read the contained drug information in the drug container. It is possible to simultaneously realize the selection of the prescription drug to be weighed in the prescription information. As a result, when a plurality of prescription drugs are included in the prescription information, the operation for selecting the prescription drug to be weighed can be omitted, and the dispensing efficiency by a user such as a doctor or a pharmacist can be improved. Can be done. Therefore, according to the present invention, it is possible to easily perform accurate weighing of a drug according to a prescription without coordinating with a higher-level system such as a dispensing support system.

Here, it is conceivable that the chemical weighing device includes a code reading means for reading information from a bar code or a two-dimensional code. In this case, the prescription information reading means reads the prescription information from the bar code or the two-dimensional code recorded on the prescription by the code reading means, and the contained medicine information reading means is the bar recorded on the medicine container. It is conceivable to read the contained drug information from the code or the two-dimensional code by the code reading means. For example, in the configuration provided with the code reading means, the user accurately and easily follows the prescription by having the code reading means sequentially read the two-dimensional code of the prescription and the bar code of the medicine container (medicine bottle, etc.). Can weigh chemicals. In particular, the user can collate the contained medicine and the prescription medicine and select the medicine to be weighed in the medicine weighing device only by having the code reading means read the barcode recorded on the medicine container. It can be realized. Further, since the prescription information reading means and the contained medicine information reading means can also be used as the code reading means, a new configuration is provided in the conventional configuration including the contained medicine information reading means and the code reading means. There is no need to add elements. The barcode is a one-dimensional code having information only in the horizontal direction, and is, for example, a JAN code or an RSS.
