The CPU is a processor that executes various arithmetic processes according to various programs. The ROM is a nonvolatile 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 developing various programs and temporarily storing data in various arithmetic processes by the CPU.

  The balance unit 12 is an example of a weighing unit that weighs a medicine placed on a stainless steel balance table 19. Specifically, the balance unit 12 is a balance unit used in a conventionally well-known electronic balance including a balance circuit, a force coil, a current / voltage conversion circuit, an A / D conversion circuit, and the like. The weight of the medicine weighed by the balance unit 12 is input to the control unit 11 as digital data. The medicine weighing device 10 is provided with a windshield cover (not shown) for preventing the powder on the balance table 19 from scattering due to the wind.

  When weighing a medicine with the medicine weighing device 10, the user places the medicine sheet 30 on the balance table 19 and then places the medicine on the medicine sheet 30. The medicine sheet 30 is provided with an RFID tag 31 as a recording medium on which various information is read and written. Here, the RFID tag 31 is provided at a position where the RFID reader / writer 14 can read and write data when the medicine sheet 30 is placed on the balance table 19. Note that the balance unit 12 sets a value obtained by subtracting a predetermined weight of the medicine sheet 30 and the RFID tag 31 as a medicine weighing value.

  The touch panel 13 detects 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 detects an operation of an operation key displayed on the display unit. And a detection unit for inputting a detection signal to the control unit 11. That is, the touch panel 13 also serves as a display unit and an input unit in the medicine 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 an RFID label using radio communication technology of RFID (Radio Frequency Identification), or reads information from the RFID tag or the RFID label. The RFID reader / writer 14 is provided adjacent to the balance table 19, and reads and writes information from and to the RFID tag 31 when the medicine sheet 30 is placed on the balance table 19. Used. Of course, the RFID reader / writer 14 may be built in the medicine weighing device 10. FIG. 2 shows an example in which the RFID reader / writer 14 is arranged on the left side of the balance board 19, but the RFID reader / writer 14 may be arranged behind the balance board 19.

  If 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 below the balance table 19, and the RFID tag 31 is attached to the medicine sheet 30. A configuration provided on the bottom surface of the is also conceivable. This allows the RFID reader / writer 14 to read and write information from and to the RFID tag 31 irrespective of the orientation of the medicine sheet 30 when the medicine sheet 30 is placed on the balance table 19.

  The data storage unit 15 stores control programs such as a drug weighing program executed by the control unit 11, various data such as a drug master (corresponding to drug information) and a generic drug master (corresponding to generic drug information). It is a USB memory, which is detachable from the medicine weighing device 10. Specifically, the data storage unit 15 is attached to and detached from a mounting portion of the USB port 16 that is exposed by removing a detachable cover (not shown) provided on the back surface of the medicine weighing device 10. Here, the detachable 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 medicine weighing device 10 without any problem in the measurement method. Therefore, by appropriately replacing the data storage unit 15, various data such as the medicine weighing program, the medicine master, and the generic medicine master can be easily updated. The data storage unit 15 is not limited to a USB memory, but may be another recording medium such as a flash memory, a memory card, or a disk. Here, the data storage unit 15 in which the medicine weighing program is recorded corresponds to a recording medium according to the present invention.

  The medicine weighing program is software that causes a computer such as the control unit 11 to execute each processing step of a medicine weighing process described later (see FIG. 5). For example, the medicine weighing program operates on an OS such as an Android (registered trademark) installed in the control unit 11. In addition, the medicine weighing program includes an inspection by the control unit 11 to check whether the weighed value of the medicine is within a range of a normal dose (appropriate amount to be taken once or once) for each medicine. The audit program to be performed is also included. For this reason, the medicine weighing device 10 can perform both the weighing of the medicine and the inspection of the normal dose alone without using another information processing device such as a computer. Here, the control unit 11 at the time of executing such an auditing process corresponds to an auditing unit.

  The drug master includes a drug code, a drug name, a JAN code (or RSS), a vial code, a division (dosage form: powdered medicine, a tablet, a liquid medicine, an external medicine, etc.), a specific gravity, and a medicine type (ordinary medicine, poisonous medicine, Drugs, powerful drugs, antipsychotics, remedies, etc.), compounding changes, excipients, precautions, regular doses (equivalent to appropriate dose information), prohibition of simultaneous use, etc. Here, the data storage unit 15 is an example of a medicine information storage unit.

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

  By the way, in the present embodiment, the medicine name (prescription medicine name, accommodation medicine name, original medicine name, prescription medicine identification information, prescription medicine identification information, original medicine identification information, generic medicine identification information) is used as the information for identifying the medicine. The case of using a generic drug name will be described as an example, but the present invention is not limited thereto, and a drug code or the like may be used. For example, when the control unit 11 and the control unit 21 to be described later compare types of drugs, they compare drug names, compare drug codes, specify drug names indicated by drug codes, and specify the drug names. , A medicine code indicated by a medicine name is identified and the medicine code is compared, or various methods such as a combination of any two or more of them are used.

  The normal dose is an appropriate amount to be taken once a day or once predetermined for each medicine. In addition, the simultaneous dosing prohibition information is information on a drug that is prohibited from being taken at the same time, which is predetermined for each of the drugs. The normal dose and the simultaneous dosing 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 on whether or not the weighed value weighed by the weighing unit 12 is within an appropriate amount range set in advance for each medicine. This is performed based on the above-mentioned usual dose. Further, the control unit 11 performs an audit on the data storage unit 15 as to whether or not a plurality of medicines contained in the prescription information read by a barcode reader 17 described later are prohibited from being taken at the same time. This is performed based on the stored simultaneous dosing information.

  When the weighed value is out of the range of the normal dose, or when there is a medicine that is previously prohibited from being taken simultaneously with the medicine recorded in the prescription, the control unit 11 sets the A warning may be displayed on the touch panel 13 or the like. Note that the control unit 11 displays the warning by text, image, sound, or light. Thereby, it is possible to prevent the prescription of a drug in an amount exceeding the normal dose or the prescription of a plurality of drugs that cause a change in combination or side effects when taken at the same time in the drug weighing stage in the drug weighing device 10. it can.

  In addition, the generic drug master includes, for the generic drug, a drug name, a JAN code (or RSS), a vial code, a division (dosage form: powdered medicine, a tablet, a liquid medicine, an external medicine, etc.), a specific gravity, and a medicine type (normal). Drugs, poisons, narcotics, powerful drugs, antipsychotics, remedies, etc.), compounding changes, excipients, precautions, regular doses (corresponding to appropriate dose information), simultaneous prohibition information, etc. are stored. In the case where the generic medicine is weighed by the medicine weighing device 10, the control unit 11 performs the inspection process based on the normal dose or the simultaneous dosing prohibition information in the same manner as described above.

  Further, in the generic drug master, correspondence 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 medicinal effect are stored in association with each other. The generic medicine master stores the name of the original medicine and the name of the generic medicine in association with the general name of the medicine. Here, the data storage unit 15 is an example of a generic drug information storage unit. The control unit 11 can obtain the name of the generic drug corresponding to each of the bar codes by referring to the generic drug master. The drug master and the generic drug master are read by the control unit 11 or edited by the control unit 11.

  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, the drug master stores drug codes A, B, and C and drug names AA, BB, and CC in association with each other. On the other hand, the generic drug master includes generic drug codes A ′, A ″, generic drug codes B ′, B ″ and generic drug names AA ′, AA ″, generic drug names B ′, BB ″. They are 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 code B ′, B ″ is associated with the drug code B, which is a generic drug corresponding to the generic drug code B ′, B ″. Thereby, the control unit 11 sets the correspondence between the medicine code A and the generic medicine codes A ′ and AA ″ and the correspondence between the medicine code B and the generic medicine codes B ′ and BB ″. Each can be learned. 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 performing communication 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 can be attached and detached. The drive power of the barcode reader 17 and the printer 18 is supplied from the USB port 16. Of course, the medicine 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, a LAN or IEEE. Further, the barcode reader 17 and the printer 18 may be communicably connected to the medicine weighing device 10 by wireless USB, wireless LAN, or the like. Further, the barcode reader 17 may be provided integrally with the medicine 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 medicine weighing device 10, the control unit 11 uses the barcode reader 17 to store prescription information including one or more prescription medicine names (an example of prescription medicine identification information) recorded (described) on 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 encode more information than a barcode having information only in the horizontal direction, and can reduce a printing area. It can be smaller. Here, the control unit 11 when executing the reading process corresponds to a prescription information reading unit. 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 ( Three times a day after each meal, etc.).

  In the medicine weighing device 10, the control unit 11 uses the barcode reader 17 to record contained medicine information including the contained medicine name recorded (described) in the medicine bottle as a barcode in the medicine bottle. Read from the (described) JAN code or vial code. Here, the control unit 11 at the time of executing the reading process corresponds to a stored medicine information reading unit.

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

  For example, it is conceivable that an information recording medium such as an RFID tag or an RFID label is provided on the medicine bottle, and the contained medicine information including the name of the medicine contained in the medicine bottle is recorded on the information recording medium. Can be In this case, the medicine weighing device 10 includes wireless reading means such as an RFID reader that reads information from the information recording medium by wireless communication, and the control unit 11 controls the information recording medium provided on the medicine bottle. It is conceivable that the stored medicine information is read by the wireless reading means.

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

  The control unit 11 may read one of the stored medicine information and the prescription information with the barcode reader 17 (code reading unit) and read the other with the wireless reading unit. On the other hand, the medicine weighing device 10 includes the wireless reading unit in place of the barcode reader 17 (code reading unit), and the control unit 11 transmits both the stored medicine information and the prescription information to the wireless communication unit. A configuration in which reading is performed by reading means is also conceivable. Of course, in a configuration in which the medicine weighing device 10 includes both the barcode reader 17 (code reading unit) and the wireless reading unit, the control unit 11 selectively selects the barcode reader 17 or the wireless reading unit. To read the stored medicine 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 for printing a result of weighing by the medicine weighing device 10 and the like. The printing layout of the weighing result is set in advance, or can be arbitrarily set in the initial setting of the medicine weighing device 10. Further, in the medicine weighing device 10, the control unit 11 can print the barcode or the two-dimensional code indicating the prescription information together with the weighing result by inputting the prescription information to the printer 18. Thereby, the medicine packaging apparatus 20 can execute a packaging operation according to the prescription information printed by the printer 18.

And a detection unit for inputting a detection signal to the control unit 21. That is, the touch panel 23 also serves as a display unit and an input unit in the medicine packaging device 20.

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

[Chemical weighing process]
Hereinafter, an example of a procedure of a medicine weighing process executed by the control unit 11 according to the medicine weighing program in the medicine weighing device 10 will be described with reference to a flowchart of FIG. Here, S1, S2,... Shown in the figure indicate the processing procedure (step) numbers executed by the control unit 11. The control unit 11 when executing the medicine weighing process corresponds to a control unit according to the present invention.

  The medicine weighing process is a process executed by the control unit 11 when the power of the medicine weighing device 10 is turned on. Here, the prescription includes the prescription delivery date, patient ID, patient name, patient's birth date, dosage form information (internal use, external use, etc.), drug information (drug code, drug name, dose), usage information (1 day) For example, after three meals, etc.) are recorded together with a two-dimensional code indicating such information. It is also assumed that the prescription drug names include three types of drugs, drug A, drug B, and drug C.

<Step S1>
First, in step S1, the control unit 11 waits for reading of prescription information (No in S1). Specifically, when the barcode reader 17 reads a two-dimensional code recorded on a prescription, the control unit 11 determines that the prescription information has been read. 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 in S1), the control unit 11 proceeds to step S2. Move to Here, the prescription information read from the two-dimensional code includes a prescription delivery date, a patient ID, a patient name, a patient's birth date, dosage form information (internal use, external use, etc.), drug information (drug code, drug The information includes information recorded in the prescription, such as name, dosage) and usage information (eg, three times a day after each meal).

  The barcode reader 17 is always readable when, for example, the power of the medicine weighing device 10 is ON. It is also conceivable that the control unit 11 shifts the barcode reader 17 to a state in which the barcode reader 17 can be read for a certain period in response to an operation input to the touch panel 13 to start weighing.

<Step S2>
In step S2, the control unit 11 displays a prescription screen 40 on the touch panel 13 based on the prescription information read in step S1. Here, FIGS. 6A and 6B show examples of the prescription screen 40, respectively.

  The prescription screen 40 shown in FIG. 6 (A) displays a dispenser name, patient name, age, weight, prescription days, minutes, drug name, dosage form (dispersed / tablet), prescription amount, and the like. Specifically, in the prescription screen 40 shown in FIG. 6A, the medicine display section 401 displays the medicine A, the medicine B, and the medicine C as prescription medicine names. In the prescription screen 40, the medicine A has a dosage form of “powder” and a prescribed amount of “0.9 g”, and the medicine B has a dosage form of “powder” and a prescribed amount of “1.2 g”. It is indicated that the drug C has a dosage form of “powder” and a prescribed amount of “0.6 g”. Hereinafter, the display mode for displaying a medicine name or the like in this manner is referred to as a medicine name display mode.

  On the other hand, on the prescription screen 40 shown in FIG. 6B, the dispenser name, patient name, age, weight, prescription days, minutes, etc. are displayed. Is not displayed. Hereinafter, such a display mode in which the medicine name or the like is not displayed is referred to as a medicine name non-display mode. The medicine name non-display mode is a display mode in which the medicine name or the like is not displayed on the prescription screen 40 so that the dispenser can perform the dispensing operation while reliably viewing the paper prescription. Thereby, in the medicine 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, it is possible to make the dispenser recognize the problem. . 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 where information not included in the two-dimensional code is recorded in the prescription, The medicine name non-display mode in which the user must surely look at the prescription is preferable.

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

<Step S3>
Next, in step S3, the control unit 11 waits for reading of the stored medicine name (No in S3). Specifically, when the barcode reader 17 reads the contained medicine information indicated by the JAN code or the medicine bottle code recorded in the medicine bottle by the barcode reader 17, the control medicine 11 reads that the contained medicine name has been read. to decide. When the user holds the JAN code or the vial code of the vial over the barcode reader 17 and the JAN code or the vial code is read by the barcode reader 17 (Yes in S3), the control is performed. The unit 11 shifts the processing to step S4.

  That is, in the medicine weighing process, the prescription information is read first, and then the contained medicine name is read. Therefore, when the stored medicine name is read first, the weighing of the medicine weighing device 10 is not started. The control unit 11 stores the result of weighing when the stored medicine name is read and weighed, and when the prescription information is subsequently read, the prescription information and the weighing result are stored. Matching with the result is also conceivable as another embodiment.

<Step S4>
Then, in step S4, the control unit 11 branches the process according to the result of collation between the contained medicine name of the contained medicine information read in step S3 and the contained medicine name of the prescription information read in step S1. I do. Specifically, in step S4, the control unit 11 determines whether the contained medicine name corresponds to any of the prescription medicine names.

  Here, if the stored medicine name corresponds to any of the prescription medicine names (Yes in S4), the process proceeds to step S5, and the stored medicine name does not correspond to any of the prescription medicine names. If it is (No in S4), the process proceeds to step S13.

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

  Therefore, the user, in the medicine weighing device 10 only by the operation of reading the JAN code or the medicine bottle code recorded in the medicine bottle to the barcode reader 17, in the medicine weighing device 10, the collation of the stored medicine name and the prescription medicine name, Selection of the medicine to be weighed can be realized. Therefore, when a plurality of prescription drug names are included in the prescription information, an operation for selecting a prescription drug name to be weighed can be omitted, and dispensing efficiency by a user such as a doctor or a pharmacist can be 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 medicine having a prescription medicine name corresponding to the stored medicine name from the prescription information. At this time, the control unit 11 causes the weighing screen 41 to display the weighed value of the medicine by the balance unit 12 and the target value of the weighing of the medicine having the prescription medicine name.

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

  Further, on the weighing screen 41 shown in FIG. 7, a determination key 411 operated to complete the weighing of the prescription drug name is displayed. Here, the enter 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 a first input unit according to the present invention.

  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, the control unit 11 displays an image or a character when the RFID tag 31 is detected by the RFID reader / writer 14 and information can be recorded on the RFID tag 31. The detection display section P161 indicated by the above is displayed. Thus, the user can easily confirm by the display of the detection display unit P161 that the RFID reader / writer 14 can write information to the RFID tag 31. When the RFID reader / writer 14 does not detect the RFID tag 31, the control unit 11 hides the detection display unit P161. In addition, the control unit 11 may display on the touch panel 13 that writing to the RFID tag 31 cannot be performed at a timing at which writing of information to the RFID tag 31 is originally performed. In the weighing screen P16, information such as the name of a drug to be weighed, a normal dose, a target amount, and a current weighing value is displayed as a weighing state in the drug weighing device 10, and the current value for the target amount is displayed. The barometer display section P162 that displays the weighed value of the image as an image is displayed.

<Step S7>
Then, in step S7, the control unit 11 waits for completion of the weighing of the prescription drug name (No in S7). Specifically, the control unit 11 determines that the weighing of the prescription drug name is completed by operating the enter key 411 displayed on the weighing screen 41 as shown in FIG. When the control unit 11 determines that the weighing of the prescription drug name is completed (Yes in S7), the control unit 11 shifts the processing 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.

  In step S7, when the medicine sheet 30 is lifted in a state where the weighing value of the balance unit 12 is stable for a predetermined time (for example, 1 second) for a predetermined time (for example, 1 second), the controller 11 It is also conceivable that it is determined that the weighing has been completed. When the weighing value of the balance unit 12 is stable for the predetermined time, "→" is displayed on the weighing screen shown in FIG. For example, the control unit 11 can determine that the medicine sheet 30 has been lifted on the condition that the weighed value of the balance unit 12 instantly becomes zero. However, when the medicine 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 executes the recording of information on the RFID tag 31 (S9) as needed every time the weighed value of the balance unit 12 is stabilized for the predetermined time. Thereby, when the medicine seed 30 is lifted, the final weighed value is recorded on the RFID tag 31. In addition, as a method of writing information to the RFID tag 31, when the medicine sheet 30 is placed on the medicine weighing device 10, information other than the weighing value by the balance unit 12 is written, and thereafter, the weighing value is written. It is conceivable to update only at any time. This makes it possible to update the weighed value to the latest information in a short time even if the time from when the weighed value is stabilized for a predetermined time to when the medicine sheet 30 is lifted is short. .

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

  FIG. 8A shows an example of the progress screen 42 displayed when the weighing of the medicine A is completed in the medicine name display mode. In the progress screen 42 shown in FIG. 8A, the names of the medicines whose weighing has been completed among the medicine names displayed on the medicine name display portion 401 are displayed in different colors or highlights.

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

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

<Step S9>
In step S <b> 9, the control unit 11 writes the prescription information and the weighing result (an example of weighed medicine information) to the RFID tag 31 by the RFID reader / writer 14. Here, the control unit 11 when executing such processing corresponds to a recording unit.

  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 ( 3 times a day after each meal, etc.). In addition, the weighing result includes a name of a medicine to be weighed, a target weighing value, an actual weighed value, a comparison result between the prescription medicine name and the contained medicine name, and the like. When the prescription drug name included in the prescription information is replaced with a generic drug name and weighed, information to that effect is also included in the weighing result.

  In step S9, the control unit 11 may cause the RFID tag 31 to record only a part of the prescription information. For example, when a small storage capacity is used as the RFID tag 31, it is not possible to record all of the prescription information and the weighing result. Therefore, in this case, the control unit 11 may cause the RFID tag 31 to store at least the name of the medicine to be weighed. This can prevent the hopper in the medicine packaging device 20 from being mistaken as described later. In this case, the medicine weighing device 10 and the medicine packaging device 20 are communicably connected to each other via a communication network such as a LAN or the Internet, and the control unit 11 transmits information that is not recorded in the RFID 31 to the medicine packaging device. Transmission to the device 20 is conceivable.

  Further, in the configuration in which the medicine weighing device 10 and the medicine packaging device 20 are connected via the communication network, simple fixed information stored in the medicine weighing device 10 in association with the prescription information and the weighing result ( It is also conceivable to record an identification number of information on the RFID tag 31. In this case, when the fixed information is read by the medicine packaging apparatus 20, the prescription information and the weighing result corresponding to the fixed information are transmitted from the medicine packaging apparatus 20 to the medicine weighing apparatus 10. A request is made. Thereby, the prescription information and the weighing result corresponding to the fixed information are transmitted from the medicine weighing device 10 to the medicine packaging device 20 via the communication network.

  Note that the processing procedure of the step 8 and the step S9 may be executed in the reverse order or may be executed substantially in parallel. That is, the prescription information and the weighing result may be recorded in the RFID tag 31 in the step S9 immediately after it is determined that the weighing is completed in the step S7.

<Step S10>
Thereafter, in step S10, the control unit 11 determines whether or not the next medicine name has been read by the barcode reader 17. If the control unit 11 determines that the next stored medicine name has been read (Yes in S10), the control unit 11 shifts the processing to step S4. On the other hand, when the next stored medicine name is not read (No in S10), the control unit 11 shifts the processing to step S11.

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

  When the control unit 11 determines that the weighing of all the prescription information has been completed (Yes in S11), the process proceeds to step S12. On the other hand, when the weighing of all the prescription information has not been completed (No in S11), the control unit 11 shifts the processing to the step S10.

  By the way, when the completion key 421 is operated, if there is a prescription medicine name whose weighing is not completed among the prescription medicine names included in the prescription information, the user may forget the weighing. Therefore, when the control unit 11 determines in step S11 that the operation of the completion key 421 has been performed, the completion of the 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 enter key 411 among the drug names, it may be displayed on the touch panel 13 to that effect. Thereby, it is 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 step 7. Here, the control unit 11 when executing the display processing corresponds to an incomplete display unit. In addition, the control unit 11 may display the display using characters, images, sounds, or light.

  However, the prescription information may include a medicine such as an external medicine, a liquid medicine, a tablet, and a heating agent (packing a predetermined amount of powdered medicine or tablets) which are not to be weighed by the medicine weighing device 10. In this case, since it is normal that the weighing of the medicines not to be weighed by the medicine weighing device 10 is incomplete, it is not warned that the user has forgotten to weigh. However, if necessary, a warning that the medicine is not to be weighed by the medicine weighing device 10 may be displayed as a warning of forgetting to weigh. As a result, it is 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 is not completed, the control unit 11 may perform the warning display only when the prescription drug name is a powdered drug. Conceivable. This is because powdered medicine is likely to be weighed by the medicine weighing device 10, and there is a high possibility that the user has forgotten to weigh.

  Further, it is conceivable to store in advance the drug type and the like that are not weighed by the drug weighing device 10 in the data storage unit 15 or the like. For example, it is conceivable that the heating agent is stored as a medicine type not to be weighed. Thereby, the control unit 11 can not perform the warning display when the weighing of the prescription medicine name corresponding to the medicine type not subject to the weighing is not completed. As a result, a warning is displayed only when necessary, and unnecessary warning can be prevented. Of course, a configuration in which the medicine type to be weighed is stored in the data storage unit 15 in advance instead of the medicine type not to be weighed by the medicine weighing device 10 is also conceivable.

  Here, the method of displaying the warning of forgetting to weigh may be arbitrarily switchable in accordance with an operation input of the touch panel 13 according to an initial setting screen related to the medicine weighing program displayed by the control unit 11. Conceivable.

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

  For example, the control unit 11 may determine that the weighing of the previous prescription information is completed on condition that the next prescription information is read. That is, the control unit 11 determines that the weighing of the prescription information read immediately before is completed on condition that the two-dimensional code of the prescription is read by the barcode reader 17.

  It is also conceivable that the control unit 11 determines that the weighing of the prescription information is completed on condition that it is determined that the weighing of all the prescription medicine names included in the prescription information is completed. Thereby, if all the prescription medicine names included in the prescription information are medicines to be weighed by the medicine weighing device 10, it is possible to automatically determine that the weighing corresponding to the prescription information is completed. It is.

  On the other hand, when the prescription information includes a medicine that is not to be weighed by the medicine weighing device 10, it cannot be determined whether or not the weighing of the prescription information has been completed. Therefore, it is conceivable that the data storage unit 15 or the like stores a medicine type or the like that is not weighed by the medicine weighing device 10. Accordingly, the control unit 11 determines in step S11 that the weighing of the prescription drug name that does not correspond to the non-weighing target drug type among the prescription drug names included in the prescription information is completed. It can be determined that the weighing corresponding to the information has been completed. Of course, a configuration in which the medicine type to be weighed is stored in advance in the data storage unit 15 instead of the medicine type not to be weighed by the medicine weighing device 10 is also conceivable.

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

  Specifically, the patient name, the name of the medicine to be weighed, the target weighing value, and the actual weighed value in the medicine weighing device 10, the prescription medicine name and the accommodation contained in the prescription information read in step S1 are described. The result of collation with the name of the medicine, weighing time, weighing operator, and the like are printed. That is, the control unit 11 causes the printer 18 to print only a record regarding the medicine weighed by the medicine weighing device 10. In the medicine weighing device 10, since the prescription information and the weighing result are recorded in the RFID tag 31, it is not necessary to perform printing by the printer 18 every time a prescription medicine is weighed, and the weighing of the prescription information is performed. Upon completion, the weighing result may be printed. Of course, it is also conceivable as another embodiment that the control unit 11 causes the printer 18 to print the weighing result every time the prescription medicine is weighed.

<Step S13>
On the other hand, in step S4, when the stored medicine name read in step S3 does not correspond to any of the prescription medicine names (No in S4), the control unit 11 executes the processing in step S13 and thereafter. .

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

<Step S14>
In step S14, the control unit 11 causes the touch panel 13 to display a warning screen 43 indicating that the medicine is different, as shown in FIG. 9A, and returns the process to step S3. Thus, it is possible to warn the user that the selection of the medicine bottle is incorrect, and it is possible to prevent a wrong medicine from being prescribed. The warning is not limited to the display of characters and images on the touch panel 13. For example, the medicine weighing apparatus 10 may include a speaker, and the control unit 11 may display that the medicine is different depending on the speaker. Further, the medicine weighing device 10 may have an LED for displaying a warning, and the control unit 11 may display that the medicine is different by light by turning on or off the LED.

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

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

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

  Note that the generic drug name may be recorded as a prescription drug name in the prescription. Therefore, in the step S15, it is determined whether or not the accommodated drug name corresponds to either the name of the original drug or the name of the generic drug, and in the step S16, the corresponding name of the original drug or the name of the generic drug is determined. It is also conceivable as another embodiment to determine whether the corresponding generic drug name or the name of the original drug corresponds to any of the prescription drug names.

<Step S17>
In step S17, the control unit 11 displays a confirmation screen 44 indicating that the medicine having the generic drug name is to be used. FIG. 9B shows an example of the confirmation screen 44. As shown in FIG. 9 (B), the confirmation screen 44 displays that the medicine with the contained medicine name is a generic medicine and an inquiry as to whether or not to approve the use of the generic medicine. In addition, the confirmation screen 44 displays an approval key 441 operated when approving the use of the generic drug, and a cancel key 442 operated when not approving the use of the generic drug.

<Step S18>
Then, in step S18, the control unit 11 determines whether or not the use of the generic drug has been approved. Specifically, the control unit 11 determines which of the approval key 441 and the cancel key 442 has been selected in 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 in S18), and shifts the processing to the step S3.

  When the approval key 441 is operated, the control unit 11 determines that the use of the generic drug is approved (Yes in S18), and shifts the process to step S5. Thereby, the control unit 11 selects the prescription drug name corresponding to the generic drug name among the prescription drug names included in the prescription information in the step S5 as a weighing target, and in the step S6, The weighing screen 41 on which the generic drug name and the weighing target value are displayed is displayed on the touch panel 13. In addition, when the prescribed amount of the generic drug name for producing the same medicinal effect as the prescribed amount for the generic drug name is different, the control unit 11 adjusts the prescribed amount of the generic drug name based on the generic drug master. It is conceivable to calculate the prescription amount of the corresponding generic drug name as the weighing target value.

<Step S19>
On the other hand, when the stored medicine name does not correspond to any of the prescription medicine name and the generic medicine name (No in S4, No in S15), the control unit 11 executes the processing of step S19 and subsequent steps. In addition, even when the name of the innovator drug corresponding to the name of the generic drug that matches the name of the accommodated drug does not correspond to any of the prescription drug names (No in S16), the control unit 11 performs the operations in and after step S19. Execute the process.

  In step S19, the control unit 11 causes the touch panel 13 to display a warning screen 45 indicating that the medicines are different. Thus, it is possible to warn the user that the selection of the medicine bottle is incorrect, and it is possible to prevent a wrong medicine from being prescribed. The warning is not limited to the display of characters and images on the touch panel 13. For example, the medicine weighing apparatus 10 may include a speaker, and the control unit 11 may display that the medicine is different depending on the speaker. Further, the medicine weighing device 10 may have an LED for displaying a warning, and the control unit 11 may display that the medicine is different by light by turning on or off the LED.

  FIG. 9C shows an example of the warning screen 45. As shown in FIG. 9C, the warning screen 45 displays that the medicine is different and an inquiry about whether or not to register a generic medicine name. In addition, the warning screen 45 displays a generic drug registration key 451 operated when performing generic drug registration and a cancel key 452 operated when not performing generic drug registration.

<Step S20>
Then, in step S20, the control unit 11 determines whether or not an operation for performing the generic drug registration has been performed. Specifically, the control unit 11 determines which of the generic drug registration key 451 and the cancel key 452 has been selected in step S20.

  Here, when the cancel key 452 is operated, the control unit 11 determines that the generic drug registration is not to be performed (No in S20), and shifts the process to step S3. When the generic drug registration key 451 is operated, the control unit 11 determines that the generic drug registration is to be performed (Yes in S20), and shifts the processing 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 causes the touch panel 13 to display a registration screen 51 for registering the generic drug name in the generic drug master, and the generic drug in response to an operation input according to the display of the registration screen 51. Register your first name. Further, the control unit 11 corrects the correspondence between the name of the original drug and the name of the generic drug in the registered generic drug master in accordance with an operation input by the user on the touch panel 13.

  FIGS. 10A and 10B show an example of the registration screen 51. FIG. As shown in FIG. 10A, on the initial screen of the registration screen 51, items such as a drug code, a drug name, a classification, a specific gravity, a drug type, a combination change, a shaped drug, a unit, and weighing can be set. . Then, the control unit 11 registers the generic drug name in the generic drug master according to the operation of the registration key 511, and closes the registration screen 51 according 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, as shown in FIG. 10B, the control unit 11 changes the setting items on the registration screen 51 to the name of the original drug, the JAN code, and the vial code. Change to In FIG. 10B, a JAN import key 515 and a normal dose key 516 are displayed. The control unit 11 captures a JAN code from a barcode attached to a medicine bottle by the barcode reader 17 in response to an operation of the JAN capture key 515. Further, the control unit 11 opens a normal dose setting screen for setting a normal dose corresponding to the generic drug name in response to the operation of the normal dose key 516, and uses the normal dose setting screen in accordance with the input of the normal 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.

  Thereafter, the control unit 11 shifts the processing to step S15. That is, the user can temporarily suspend the weighing operation on the prescription information and edit the generic drug master, and then resume the weighing operation on the prescription information as it is. Therefore, the user can appropriately edit the generic medicine master in the daily operation using the medicine weighing device 10 to enrich the contents. On the other hand, when the weighing operation (drug weighing process) based on the prescription information is temporarily terminated and the generic drug master is edited on an initial setting screen or the like, the weighing operation (drug weighing process) based on the prescription information is thereafter performed. ) Must be performed again from the beginning, and the user is forced to perform complicated work.

  As described above, the user using the medicine weighing device 10 can accurately and easily read the medicine according to the prescription by causing the barcode reader 17 to sequentially read the two-dimensional code of the prescription and the barcode of the medicine bottle. Weighing can be performed.

  In particular, when the user causes the barcode reader 17 to read the barcode of the medicine bottle, the medicine weighing device 10 performs the collation of the contained medicine name and the prescription medicine name, and starts the weighing of the weighing target from which weighing is started. 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 the operation of selecting the prescription drug name to be weighed.

[Chemical packaging processing]
Subsequently, an example of a procedure of a medicine packaging process executed by the control unit 21 according to the medicine packaging program will be described with reference to a flowchart of FIG. Here, S31, S32,... Indicate the processing procedure (step) numbers executed by the control unit 21.

<Step S31>
First, in step S31, the control unit 21 determines whether or not prescription information has been input. Specifically, the control unit 21 determines whether or not prescription information has been read from the RFID tag 31 by the RFID reader / writer 24. As described above, in the medicine weighing system 1, since the prescription information can be read from the RFID tag 31 in the medicine packaging device 20, the medicine packaging device 20 is communicably connected to a host system such as a dispensing support system. No need to do. Further, in the medicine packaging apparatus 20, since the prescription information is obtained from the RFID tag 31, in order to input the prescription information in the medicine packaging apparatus 20 and to operate the medicine packaging apparatus 20 conventionally performed by the user. Operation work can be reduced.

  However, another embodiment in which the medicine packaging apparatus 20 is communicably connected to the host system is also conceivable. In this case, the control unit 21 determines in step S31 whether the prescription information has been input from the higher system. Further, a configuration in which the control unit 21 includes a barcode reader that reads prescription information from a two-dimensional code recorded on a prescription is also conceivable as another embodiment. In this case, the control unit 21 determines whether the two-dimensional code has been read in the step S31. Of course, the medicine packaging apparatus 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 in S31), the control unit 21 shifts the processing to step S32, and when it determines that the prescription information has not been input (S31). No side), the process proceeds to step S33.

<Step S32>
In step S32, the control unit 21 selects which of the hopper 25A and the hopper 25B is used for packaging the medicine related to the prescription information read in step S31.

  For example, when prescription information describing a medicine to be prescribed to the patient C1 is input, the hopper 25A is used for packaging the medicine, and when prescription information describing a medicine to be prescribed to the patient C2 is inputted. It is predetermined that the hopper 25B is used for packaging the medicine, and it is conceivable that allocation information indicating that fact is included in the prescription information. 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 which of the hopper 25A and the hopper 25B to use for each of the prescription information in the step S32. Is also conceivable. 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 apparatus 20 configured as described above, the user can use the hopper 25A and the hopper 25B for each of the prescription information to supply the medicine, and thus can perform the dispensing operation regarding the prescription information of a plurality of patients. Can proceed in parallel.

  However, if the dispensing operations relating to the prescription information of a plurality of patients proceed in parallel, there is a possibility that the user may inject the medicine into the hopper 25A or the hopper 25B which is opposite to the original. Therefore, in the medicine packaging process, the following steps S33 and subsequent steps prevent the user from erroneously determining the medicine supply destination.

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

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

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

  Even if the prescription information is not recorded in the RFID tag 31, in step S32, the prescription information is read from the prescription information input from the host system or the prescription information read from the prescription two-dimensional code. It is selected whether to use the hopper 25A or the hopper 25B. Therefore, if the RFID tag 31 stores at least information such as a drug name and a weighed value relating to the drug placed on the drug sheet 30, the control unit 21 determines in step S34 based on the information. You can make a decision. Specifically, the control unit 21 specifies prescription information including a prescription medicine name and a prescription amount corresponding to the medicine name and the weighed value of the medicine placed on the medicine sheet 30, and corresponds to the prescription information. The hopper 25A or the hopper 25B is selected.

<Step S35>
In step S35, the control unit 21 causes the touch panel 23 to display the selection result in step S34 as characters or images. For example, it is conceivable that the control unit 21 performs a guidance display such as “Please put A medicine into A hopper”. 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. It is also conceivable that an LED or the like is provided in each of the hopper 25A and the hopper 25B, and the control unit 21 displays the selection result by turning on one of the LEDs. Further, if the input ports of the hopper 25A and the hopper 25B can be opened and closed by a predetermined driving unit, the control unit 21 controls the driving unit to control 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 button. Further, a lock means for restricting the opening of the input port is provided at each of the input ports of the hopper 25A and the hopper 25B, and the control unit 21 releases only one of the lock means and sets the other. By setting the lock state, it is also conceivable that the user can open only the loading port to which the drug of the drug sheet 30 is to be loaded.

  As described above, in the medicine packaging device 20, the medicine is charged based on the information stored in the RFID tag 31 provided on the medicine sheet 30 which is inseparable from the medicine weighed by the medicine weighing device 10. The destination is automatically displayed. Therefore, the user can easily grasp the medicine introduction destination, and the mistake of the medicine introduction destination is prevented. Further, as a notification method of the selection result in the step S34, 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, the user can input the medicine. Can be more effectively prevented.

<Step S36>
Thereafter, in step S36, the control unit 21 controls the packaging operation performed by the packaging unit 22 based on the prescription information read from the RFID 31 and the weighing result according to a preset control condition. . Here, the control unit 21 when executing such processing corresponds to a packaging control unit.

  In the conventional medicine packaging apparatus, since detailed information of the medicine to be packed is unknown, the medicine is packaged according to a common condition that all medicines can be accurately packaged. Therefore, for example, the packaging operation may be unnecessarily delayed. However, in the medicine packaging process, since different packaging operations can be controlled based on the prescription information and the weighing result in the step S36, for example, the medicine is packaged under conditions suitable for each medicine. Can be. Specifically, the control unit 21 is preset for each type of the powdered medicine according to the prescription information read from the RFID tag 31 as the weighed medicine information and the type of medicine included in the weighing result. The operation is performed by the dividing means or the packaging means. For example, the control unit 21 prevents the scattering by reducing the packaging speed (such as the rotation speed of the annular dispensing dish in the division unit 221) when the powder of the type that is easily dispersed is packaged. It is conceivable to speed up the packing speed when packing powdered medicines of different types to perform packing quickly.

[Other examples of chemical packaging]
Here, first to third modifications, which are other examples of the medicine packaging process, will be described with reference to FIGS. Note that the same reference numerals are given to the same processing procedures as the processing procedures of the medicine packaging processing described with reference to FIG. 11, and description thereof will be omitted.

[First Modification]
As illustrated in FIG. 12, in the medicine packaging process according to the first modification, between the steps S31 and S32 illustrated in FIG. 11, steps S311 to S312 described below are performed by the control unit 21. .

<Step S311>
In step S311, the control unit 21 determines whether or not a plurality of prescription drug names are included in the prescription information input in step S31. If the control unit 21 determines that a plurality of prescription drug names are included (Yes in S311), the control unit 21 shifts the processing to step S312 and determines that a plurality of prescription drug names are not included ( (No side of S311), and the process shifts to step S32.

<Step S312>
In step S312, the control unit 21 selects which of the hopper 25A and the hopper 25B is used for each prescription drug name included in the prescription information. In addition, regarding the selection method, for example, allocation information regarding which of the hopper 25A or the hopper 25B is used for each prescription drug name is included in the prescription information, and the control unit 21 includes 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 medicine is predetermined for each medical facility or pharmacy. For example, it is conceivable that the hopper 25A and the hopper 25B are separately used for a colored chemical having a color and a colorless chemical having no color. Further, the control unit 21 automatically determines which one of the hopper 25A and the hopper 25B is used for each prescription drug name, such as alternately using the hopper 25A and the hopper 25B for each prescription drug name. It is also conceivable to assign to

  In the case where the prescription information includes two prescription drug names that are predetermined as drugs to be contained in the same packaging paper among a plurality of prescription drug names, the control unit 21 sets the It is selected to use the hopper 25A on the one hand and the hopper 25B on the other hand. Thereby, in the medicine packaging operation by the packaging unit 22 of the medicine packaging apparatus 20 in the step S36, the prescription medicines supplied to each of the hopper 25A and the hopper 25B are packaged in the same wrapping paper in units of one dose. Can be done. For example, when one prescription contains two (a plurality of) types of medicines having different taking times, the medicine packaging apparatus 20 operates as follows. Specifically, consider a case where powdered medicine M1 to be taken in the morning, noon and evening and powdered medicine M2 to be taken in the morning and evening are included in one prescription information. In this case, in the medicine packaging operation in step S36, the control unit 21 refers to each of the powdered medicines M1 and M2 from the prescription information, and the powdered medicine M1 and the powdered medicine M2 are referred to as "morning of the powdered medicine M1. And the morning of the powder M2, the day of the powder M1 and 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 medicine from the prescription information recorded on the RFID tag 31. In the medicine packaging apparatus 20, since the prescription information is obtained from the RFID tag 31, the input operation of the prescription information in the medicine packaging apparatus 20 and the operation of the medicine packaging apparatus 20 which have been performed by the user conventionally. Operation work is reduced.

  As described above, according to the first modification, when one prescription information corresponding to one patient includes a plurality of prescription drug names, the hopper 25A and the hopper 25B are provided for each prescription drug name. Can be used properly, and dispensing operations of a plurality of prescription drugs can proceed in parallel. In addition, when there are prescription drugs to be packaged at the same time, it is possible to use the hoppers 25A and 25B at the same time and to dispense the prescription drugs in the same packaging paper in units of one dose.

[Second Modification]
As shown in FIG. 13, in the medicine packaging process according to the second modification, after the step S32 and the step S312 in the medicine packaging process according to the first modification shown in FIG. Steps S313 to S315 described below are performed.

<Step S313>
In step S313, the control unit 21 determines whether there is uncompleted prescription information for which the medicine packaging operation performed in step S36 has not been completed for all medicines. Here, if the control unit 21 determines that the uncompleted prescription information exists (Yes in S313), the control unit 21 shifts the processing to step S314. If the uncompleted prescription information does not exist (S313). (No side), the process proceeds to step S33.

<Step S314>
In step S314, the control unit 21 determines whether a hopper used in the medicine packaging operation related to the incomplete prescription information has been selected. When simply referred to as “hopper”, one or both of the hoppers 25A and 25B are indicated. When the hopper used in the medicine packaging operation related to the uncompleted prescription information or the hopper to be used is not selected (No in S314), the control unit 21 shifts the processing to the step S33. Let it. Accordingly, both the hopper 25A and the hopper 25B are used, for example, when there is no medicine to be packaged with the same packaging paper in the uncompleted prescription information, or when there is only one remaining medicine. When not necessary, the hopper 25A and the hopper 25B can be used for dispensing medicines described in different prescription information.

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

<Step S315>
In step S315, the control unit 21 causes the process to wait until the medicine packaging operation relating to the uncompleted prescription information is completed, and thereafter shifts the process to step S33. In this case, it is conceivable that the control unit 21 displays an error for notifying the user that there is no usable hopper using characters, images, sounds, light, or the like.

  Accordingly, when it is necessary to use both the hopper 25A and the hopper 25B together, for example, when the uncompleted prescription information includes a medicine to be packaged in the same packaging paper, the prescription information is described in other prescription information. It is possible to prohibit the use of the hopper 25A and the hopper 25B in the medicine packaging operation for the performed medicine. Further, when there are two or more remaining medicines included in the uncompleted prescription information, interruption of the next prescription information is prevented, so that the prescription information can be sequentially processed, thereby preventing dispensing errors. can do.

[Third Modification]
As shown in FIG. 14, in the medicine packaging process according to the third modification, the control unit 21 executes the following steps S341 to S343 instead of the steps S34 to S35 shown in FIG. 11.

  Here, the medicine packaging apparatus 20 in which the medicine packaging process according to the third modified example is executed includes the individual RFID reader / writers 24 provided at positions respectively corresponding to the plurality of hoppers 25A and the hoppers 25B. It is necessary to have. 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 provided near the loading port of the hopper 25A, for example, a mounting table (for example, a lid of the loading port) of the medicine sheet 30. The RFID reader / writer 24B is mounted on the hopper 25B. It is arranged on a mounting table for the medicine sheet 30 provided near the inlet.

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

  Specifically, the control unit 21 allows the user to read the medicine in the medicine sheet 30 according to which of the RFID reader / writer 24 and the RFID reader / writer 24B reads the medicine name from the RFID tag 31. Determine the hopper you are about to put. Then, the control unit 21 determines 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 medicine name is the hopper selected in the step S32. Determine whether or not.

  Here, when the control unit 21 determines that the hopper to which the user is going to put the medicine in the medicine sheet 30 is correct (Yes in S341), the control unit 21 shifts the processing to step S342 and determines that the hopper is not correct (S341). No side), the process proceeds to step S343.

<Step S342>
In step S342, the control unit 21 notifies the user that the hopper to which the medicine in the medicine sheet 30 is to be injected is correct. Specifically, the control unit 21 may display that fact on the touch panel 23. It is also conceivable that the control unit 21 turns on LEDs and the like provided in the hoppers 25A and 25B in a predetermined color (such as blue or green) corresponding to a case where the hopper is correct. Of course, it is also conceivable that the hopper displays a message to the effect that it is correct. Further, the control unit 21 may automatically open the input port of the hopper or release the lock of the input port of the hopper only when the hopper to which the medicine of the medicine sheet 30 is to be input is correct. Conceivable.

<Step S343>
On the other hand, in step S343, the control unit 21 notifies the user that the hopper to which the medicine in the medicine sheet 30 is to be injected is incorrect. Specifically, the control unit 21 may display that fact on the touch panel 23. It is also conceivable that the control unit 21 turns on LEDs and the like provided in the hopper 25A and the hopper 25B in a predetermined color (red or the like) corresponding to an incorrect hopper. Of course, it is also conceivable to display by voice or the like that the hopper is wrong.

  As described above, according to the third modification, the user places the medicine sheet 30 at the position where the RFID reader / writer 24A or the RFID reader / writer 24B is provided, thereby allowing the medicine sheet 30 to be placed. Since it is possible to confirm the suitability of the destination of the medicine placed on the medicine sheet 30, it is possible to effectively prevent mistakes in the destination of the medicine placed on the medicine sheet 30.

  In the third modification, the steps S341 to S343 are executed in place of the steps S34 to S35 in the medicine packaging process (see FIGS. 12 and 13) according to the first and second modifications. It is also possible. Accordingly, for example, when the prescription information includes a plurality of medicines, the user determines whether or not the medicine input destination of the medicine sheet 30 is appropriate as the hopper selected for each medicine (S312). Can be easily confirmed.

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

[Prescription information input mode]
In the medicine weighing device 10, the input mode of the prescription information can be arbitrarily selected. For example, the control unit 11 causes the touch panel 13 to display an initial setting screen relating to the medicine weighing program, and selects the input mode in accordance with an operation input performed according to the initial setting screen.

  The input mode includes a barcode reading mode for reading the prescription information using the barcode reader 17, a manual input mode for manually inputting the prescription information using the touch panel 13, and a host system of the medicine weighing device 10. And a network input mode for inputting the prescription information via a communication network. When the medicine weighing device 10 has the network input mode, the medicine weighing device 10 has a communication interface for communicating with a host system such as a dispensing support system via a communication network such as a LAN or the Internet. Prepare. And the control part 11 performs the same processing procedure as the said chemical | medical agent weighing processing (refer FIG. 5) also in the said network input mode, for example. That is, the reading of the prescription information from the prescription in the step S1 merely replaces the input of the prescription information from the upper system. In the case of the 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 barcode reader 17 reads the two-dimensional code. Switching to the mode is also conceivable.

  Further, a configuration is also conceivable in which the medicine weighing device 10 has a microphone for inputting voice and a voice recognition unit for executing voice recognition processing for inputting information in accordance with the voice input to the microphone. The voice recognition unit is, for example, the control unit 11 when performing the voice recognition process. In such a configuration, the dispensing worker 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 into the medicine weighing device. 10 can be entered. That is, it is conceivable that the medicine 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 information about a plurality of drug names is input to the medicine weighing device 10, and then the control unit 11 reads a plurality of the prescription information according to the prescription information. It is conceivable to continuously perform weighing on the name of the drug. Further, it is also conceivable that the control unit 11 executes weighing of a drug name each time one drug name is read out of the prescription information recorded in the prescription.

[Prescription batch reading mode]
The medicine weighing process (see FIG. 5) is a processing procedure for reading prescription information from one prescription and sequentially weighing each prescription medicine name included in the prescription information. On the other hand, a configuration is conceivable in which the medicine weighing device 10 has a prescription batch reading mode in which prescription information can be read continuously from a plurality of prescriptions and weighing of each of the prescription information can be performed in parallel. The prescription batch reading mode is realized by the control unit 11 executing the medicine weighing program.

  Specifically, in the prescription batch reading mode, substantially the same process as the medicine weighing process is executed. However, in step S3, when the stored medicine name is not read (No in S3), The control unit 11 shifts the processing to step S1. Thus, the user can cause the barcode reader 17 to continuously read a plurality of prescriptions. Then, the control unit 11 accumulates and stores prescription information read from the plurality of prescriptions in a RAM or the like. FIG. 15A shows prescription information read from a plurality of prescriptions D1 to D3. The prescription D1 includes drugs A to C, the prescription D2 includes drugs D to F, and the prescription D3 includes drugs G to I.

  Thereafter, when the stored medicine name is read (Yes in S3), in the next step S4, the control unit 11 determines that the stored medicine name is any one of the plurality of prescription medicine names of the plurality of prescription information. Is determined. More specifically, when “medicine E” is read as the contained medicine name after the prescriptions D1 to D3 shown in FIG. 15A are read (Yes in S3), “prescription D2 is included in the prescription D2. Since the “drug E” is included (Yes in S4), the process proceeds to step S5. In step S5, the medicine E included in the prescription information corresponding to the prescription D2 is automatically selected as a weighing target (S5), and the prescription amount of the medicine E recorded in the prescription D2 is displayed on the weighing screen. 41 is displayed (S6).

  Here, the stored medicine name may correspond to a prescription medicine name 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.

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

  In this case, if the read medicine name is “medicine E”, the medicine E is included in both the prescription D2 and the prescription D3, so that the control unit 11 sets the prescription D2. Alternatively, a prescription selection screen 61 for selecting any one of the prescriptions D3 is displayed on the touch panel 13. FIG. 15 (C) 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 medicine E recorded on 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, it is possible to continuously advance the weighing of each medicine recorded in the prescription. Dispensing efficiency can be increased.

  By the way, when one patient is examined by a plurality of medical departments, the medicine may be weighed according to a plurality of prescriptions prescribed for each medical department. Also in this case, as described above, a configuration in which prescription information is continuously read from a plurality of prescriptions is preferable. Thereby, after the barcode reader 17 reads a plurality of prescriptions continuously, it is possible to continuously advance the weighing of each medicine recorded in the prescriptions, thereby improving the dispensing efficiency of the user. . 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. May be displayed. If the controller 11 selects to integrate a plurality of prescriptions into one prescription information according to the pop-up screen, the controller 11 generates one prescription information from the plurality of prescription information read from the plurality of prescriptions. Thereafter, the medicine weighing device 10 performs weighing according to the generated prescription information after integration.

  Further, the control unit 11 can obtain all the prescription medicine 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 determines that there is a pre-prohibited medicine of all the prescription medicine names recorded in each of the prescriptions. It is conceivable to determine the presence or absence. For example, the medicines prohibited from being taken at the same time are predetermined as a plurality of medicines that cause a change in combination or side effects. At this time, the control unit 11 checks whether or not a plurality of medicines included in each of the prescription information are prohibited from being taken at the same time. This is performed based on the prohibition information. Then, when there is a medicine that is previously prohibited from being taken simultaneously among all the prescription medicine 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. It is possible. Note that the control unit 11 displays the warning by text, image, sound, or light. Thereby, the prescription of a plurality of medicines that cause a change in combination and side effects when taken at the same time can be prevented at the medicine weighing stage in the medicine weighing device 10.

[Other embodiments]
Hereinafter, a 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 denoted by the same reference numerals, and description thereof will be omitted.

  As shown in FIG. 17, the medicine weighing system 2 includes one or a plurality of the medicine weighing devices 10, one or a plurality of the medicine packaging devices 20, and a host system 70 connected to each of the medicine weighing devices 10. Is provided. In the medicine weighing system 2, the medicine weighing device 10, the medicine packaging device 20, and the host system 70 are communicably connected via a network N such as a LAN or the Internet.

  The control unit 11 of the medicine weighing device 10 includes a CPU 111, an SD card 112, and a RAM 113. The SD card 112 is a storage unit that stores various programs such as a kernel 114, an OS 115, and a weighing unit application 116 that are executed by the CPU 111. In place of the SD card 112, a storage unit such as a ROM storing the various programs may be provided. The kernel 114 is a software program such as Linux (registered trademark), and the OS 115 is an operating system such as Android (registered trademark) or iOS (registered trademark). Further, the weighing unit application is a software program for operating the medicine weighing device 10 as a normal electronic balance. That is, in the medicine weighing device 10, the control unit 11 built in the medicine weighing device 10 executes various processes such as the medicine weighing process (see FIG. 5) executed by the medicine weighing device 10. Program, database, etc. are not stored. Therefore, in the medicine weighing device 10, the stability of the function as the electronic balance is ensured.

  On the other hand, the data storage unit 15 detachable 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 indicating an operation history of the medicine weighing device 10. It is also conceivable that a card slot is provided instead 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 or a print form. The medicine weighing program 154 is a software program for causing the control unit 11 to execute various processes such as the medicine weighing process (see FIG. 5). The database 155 stores various types of 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 a startup process (see FIG. 39) described later. The database dump file 156 is used for restoring the data at the time of backup when a part or all of various data stored in the database 156 becomes abnormal.

  On the other hand, the medicine packaging device 20 includes a data storage unit 26 such as a hard disk or an SSD, and a printing unit 27 that prints information on a wrapper used for packaging medicines in the packaging unit 22. The data storage unit 26 is provided with a shared folder accessible from each of the medicine weighing devices 10 via the network N. Thereby, in each of the medicine weighing devices 10, the control unit 11 stores the prescription information, the weighing result, and a 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. Thereby, the control unit 21 reads the tray number from the RFID tag 31 of the medicine sheet 30, for example, and stores the prescription information and the weighing result corresponding to the medicine sheet 30 based on the tray number in the data. It can be read from the unit 26.

  The host system 70 is, for example, an electronic medical record system or a dispensing support system, and is an information processing device such as a personal computer for inputting and managing the prescription information on prescription drugs 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, a RAM, a ROM, and the like, and controls the host system 70 as a whole. The data storage unit 72 is a non-volatile storage unit such as a hard disk or an 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 medicine weighing device 10 in response to a transmission request from the medicine weighing device 10. . At this time, the control unit 71 locks the prescription information selected as a weighing target in any of the medicine weighing devices 10 and performs an exclusive process so that the same prescription information is not selected by another medicine weighing device. Execute Thereby, duplication of the weighing operation based on the medicine weighing information using the plurality of medicine weighing devices 10 is prevented. Note that the control unit 71 can also transmit the prescription information to the medicine packaging device 20 in response to a transmission request from the medicine packaging device 20. Further, the control unit 71 can also actively transmit the prescription information to the medicine weighing device 10 or the medicine packaging device 20.

  In the medicine weighing system 2, the medicine weighing device 10 reads the prescription information from a prescription by the barcode reader 17 and inputs the prescription information on the touch panel 13. It is possible to obtain information. When the prescription information is obtained from the host system 70, the control unit 11 causes the data storage unit 15 to store the prescription information. Thereby, the control unit 11 can read the prescription information arbitrarily selected from the data storage unit 15 in accordance with a user operation on the touch panel 13. Further, as 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 host system 70 via the network N, read out the prescription information, and copy the prescription information to the data storage unit 15.

[Prescription input processing]
In the medicine 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. Execute prescription input processing. For example, the prescription input process is a process executed between the step S1 and the step S2 in the medicine weighing process. Note that the prescription input process described here may be executed by the medicine weighing device 10 in a configuration in which the medicine weighing device 10 is not connected to the host system 70, for example, in the medicine weighing system 1.

  Hereinafter, an example of the procedure of the prescription input process 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 information on the expiration date included in the prescription information. Here, when the expiration date has passed (No in S41), the control unit 11 shifts the processing to step S411. Then, in step S411, the control unit 11 displays the fact that the expiration date has passed on the touch panel 13 and notifies the user of the fact that the expiration date has passed. To end. On the other hand, when the control unit 11 determines that it is within the validity period (Yes in S41), the control unit 11 shifts the processing to step S42.

<Steps S42 to S43>
In steps S42 to S43, the control unit 11 analyzes usage information and medicine information of one or a plurality of recipes included in the prescription information and acquires information such as usage of each recipe and prescription medicine. In addition, the said recipe means the prescription of a dosage unit, and is abbreviated as "Rp" at the time of the display or printing in the said chemical weighing system 2. Hereinafter, 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 non-uniform record is a recipe in which the prescription amount of the prescription medicine varies depending on the time of taking. For example, for the medicine A, a recipe whose prescription amount is 1 mg, 1 mg, and 2 mg in the morning, afternoon, and evening doses corresponds to the non-uniform record. Here, when the control unit 11 determines that the unequal record exists (Yes in S44), the control unit 11 shifts the processing to step S45, and determines that the unequal record does not exist (No in S44). The process moves to step S46.

<Step S45>
In step S45, the control unit 11 executes a recipe division process of dividing a recipe in which the unequal record exists among the recipes included in the prescription information into a recipe for each dosage period. Here, FIG. 19 shows an example of the recipe Rp1, which is an example of the non-uniform 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 prescribed amount of “Drug A” in the morning, noon, and evening is different from the prescribed 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 to only morning, a recipe Rp12 corresponding to only daytime, and a recipe Rp13 corresponding to only evening. If the daily amount in the morning and the daytime is the same and only the daily amount in the evening is different, it is conceivable to generate the recipe by dividing only the evening. That is, it is conceivable that the control unit 11 divides, as a different recipe, only the taking times having different prescription amounts among the plurality of taking times. Whether or not to execute the recipe division process in step S45 can be changed by the control unit 11 in accordance with a user operation on the touch panel 13 in an initial setting of the medicine weighing device 10 or the like.

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

<Step S47>
In step S47, the control unit 11 executes a recipe unifying process of unifying a plurality of recipes having the same usage and the number of days into one recipe in the prescription information. Here, FIG. 20 illustrates an example of the recipes Rp21 to Rp23 before being combined, and the recipe Rp2 and the recipe Rp23 after the recipe combining processing. 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 the same 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. Thereby, one package of a plurality of prescription drugs is realized in the packaging process of the drug packaging apparatus 20 performed based on the prescription information after being compiled by the drug weighing apparatus 10. Whether or not to execute the recipe combining process in step S47 can be changed by the control unit 11 according to a user operation on the touch panel 13 in an initial setting of the medicine weighing device 10 or the like.

<Step S48>
In step S48, the control unit 11 stores the prescription information after the recipe division processing in step S45 or the recipe unification processing in step S47 in the data storage unit 15, and stores the prescription information in the data storage unit 15. The data is stored in the shared folder of the data storage unit 26 of the medicine packaging device 20. Thus, the medicine packaging apparatus 20 can also read out the prescription information and execute the packaging process.

[Display control processing]
In the medicine weighing device 10, the control unit 11 executes a display control process of controlling a screen display on the touch panel 13 according to a preset type of system interlocking of the medicine weighing device 10. Specifically, in the medicine weighing device 10, a system interlock selection screen P <b> 21 for selecting the type of the system interlock is displayed on the touch panel 13 by the control unit 11 in an initial setting or the like. FIG. 21 is a diagram showing an example of the system interlocking selection screen P21. As shown in FIG. 21, in the system link selection screen P21, the types of the system link are “sequential”, “patient ID”, “voucher number”, “unprocessed”, “processed”, and “single”. Are displayed on the screen. Then, the control unit 11 sets the type of the system interlock according to a user operation on the touch key on the touch panel 13. When the type of system linkage of the medicine weighing device 10 is set to “single”, the control unit 11 sets the medicine weighing device 10 to be usable as an electronic balance and inputs the prescription information. Do not accept.

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

<Step S51>
In step S51, the control unit 11 determines whether or not the type of the system interlock of the medicine weighing device 10 is set to “sequential”. “Sequential” is an operation mode in which the control unit 11 causes the touch panel 13 to sequentially display recipes of the prescription information acquired from the host system 70. Here, if the type of the system interlock is “sequential” (Yes in S51), the control unit 11 shifts the processing to step S52, and if not “sequential” (No in S51), The process is shifted 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 medicine weighing device 10. Here, FIGS. 23 and 24 are diagrams 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 a dispenser, a prescription number, days, minutes, age, weight, and the like of the recipe information are displayed. Note that the control unit 11 can also directly input the recipe information in accordance with a user operation for each display location of the prescription information area A231.

  Further, as shown in FIG. 23, the prescription screen P23 includes a medicine display area A232 in which a daily amount and a total amount of each prescribed medicine to be weighed are displayed. In addition, the control unit 11 alternately switches the display contents of the daily amount and the total amount for each of the prescription medicines between an actual measurement amount and a target amount in accordance with a user's touch operation on the medicine display area A232. The actually measured amount is a value actually measured by the medicine weighing device 10, and the target amount is a value determined as a prescribed amount in the recipe information. Note that a menu key K233 is displayed on the prescription screen P23, and the control unit 11 performs an initial setting for starting the setting of the type of the system interlock in response to a user operation of the menu key K233. Display the menu screen.

  Further, as shown in FIG. 23, the prescription screen P23 includes a development area A234. When the user performs a touch operation or an upward flick operation on the development area A234, the control unit 11 expands the display area of the development area A234 as shown in FIG. Then, in the development area A234, various touch keys indicating contents operable on the prescription screen P23 are displayed. For example, a setting key K235 for setting the type of packaging paper used in the packaging operation of the medicine packaging apparatus 20 is displayed in the development area A234. The control unit 11 displays a setting screen for setting the type of the packaging paper according to a 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 medicine packaging device 20. For example, the type of the packaging paper is distinguished by the material and the length of the packaging paper, and a plurality of combinations for selecting the material and the 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 type of system linkage of the chemical weighing device 10 is set to “unprocessed” or “processed”. The “unprocessed” is an operation mode in which the control unit 11 displays only the prescription information for which the weighing has not been completed by the medicine weighing device 10. “Processed” is an operation mode in which the control unit 11 displays only the prescription information whose weighing is completed by the medicine weighing device 10. Here, when the type of the system interlock is “unprocessed” or “processed” (Yes in S53), the control unit 11 shifts the processing to step S54, and executes “unprocessed” or “processed”. If not, the process proceeds to step S56.

<Step S54>
In step S54, the control unit 11 determines whether a prescription unit or a recipe unit is selected as a display format when selecting a weighing target in the initial setting of the medicine weighing device 10. Here, when determining that the prescription unit is selected, the control unit 11 shifts the processing to step S551 (Yes in S54), and determines that the recipe unit is selected (No in S54). Side), the process proceeds 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, when the type of the system interlock is “unprocessed”, the prescription list screen P25 displays a list of the prescription information for which the medicine weighing device 10 has not completed weighing. If the type of the system linkage is “processed”, a list of the prescription information whose weighing has been completed by the medicine weighing device 10 is displayed on the prescription list screen P25. Here, FIGS. 25 and 26 are diagrams 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 medical department, a recipe number (Rp number), a drug name, and a deletion corresponding to the prescription information are displayed. .

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

  Meanwhile, when displaying the prescription list screen P25, the control unit 11 requests the upper system 70 to transmit a predetermined number of the 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 the prescription information in the data storage unit 15. In this case, the control unit 11 switches the contents of the prescription information displayed on the prescription list screen P25 according to the operation of “previous data” or “next data” displayed in the development area A251. Specifically, in response to the operation of “previous data” displayed in the development area A251, the control unit 11 transmits the predetermined number of the prescription information before the currently displayed prescription information to the higher order. Request to system 70. Similarly, in response to the operation of the “next data” displayed in the development area A251, the control unit 11 transmits the predetermined number of pieces of the prescription information after the currently displayed prescription information to the host system 70. Request to. Thereby, the control unit 11 stores the predetermined number of the prescription information transmitted from the host system 70 in the data storage unit 15 and displays the prescription information on the prescription list screen P25. In this way, if the medicine weighing device 10 acquires only the necessary prescription information from the host system 70, the prescription is used in a configuration in which the plurality of medicine weighing devices 10 are connected to the host system 70. Information exclusion processing can be realized. Specifically, as described above, in the host system 70, the control unit 71 locks the prescription information selected as a weighing target in one of the medicine weighing devices 10 and locks the other prescription information in the other medicine weighing devices 10 It is conceivable to control so as not to send to the user.

  On the other hand, a configuration in which the medicine weighing device 10 acquires the prescription information from the host system 70 according to, for example, a dispensing system prescription IF sharing specification (NSIPS) is also conceivable. The prescription information may be transmitted from the host system 70 to the medicine packaging device 20 and then transmitted from the medicine packaging device 20 to the medicine weighing device 10. Then, the control unit 11 causes the data storage unit 15 to store the prescription information acquired from the host system 70 or the medicine packaging device 20. In this case, the data storage unit 15 can store not only the predetermined number that can be displayed on the prescription list screen P25 but also a large number of the prescription information. Therefore, the control unit 11 can change the prescription information displayed on the prescription list screen P25 by sliding the prescription information in response to the user's vertical flick operation on the prescription list screen P25. In this case, “previous data” and “next data” are not displayed in the development area A251. Of course, the control unit 11 requests the upper system 70 to transmit more prescription information than the predetermined number that can be displayed on the prescription list screen P25 and receives the prescription information, and the prescription list screen P25 A configuration is also conceivable in which the prescription information can be slid and displayed in response to a vertical flick operation in.

  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 a selected state. To the effect. Thereafter, when the user performs a rightward or leftward flick operation on the touch panel 13 in a state where any of the prescription information is selected, the control unit 11 displays the details of the selected prescription information. The displayed prescription medicine information screen P27 is displayed on the touch panel 13. FIG. 27 is a view showing an example of the prescription medicine information screen P27. On the prescription drug information screen P27, prescription drug information (drug name, usage, 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 medicine information screen P27, the control unit 11 changes the display color of the display position corresponding to the recipe and indicates that the selected state is selected. Is shown. After that, when the user operates a determination key displayed after a user performs a touch operation or an upward flick operation on the development area A271 of the prescription medicine information screen P27, the control unit 11 performs the selection. Is determined as a weighing target, and the prescription screen P23 is displayed. In the prescription medicine information screen P27, the control unit 11 changes the display position of the prescription medicine or recipe whose weighing has already been completed to a display color different from the display color indicating that the prescription is being selected. To the effect.

<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, when the type of the system interlock is “unprocessed”, the recipe list screen P28 displays a list of the recipe information for which the chemical weighing device 10 has not completed weighing. If the type of the system linkage is “processed”, a list of the recipe information whose weighing has been completed by the chemical weighing device 10 is displayed on the recipe list screen P28. FIGS. 28 and 29 are views showing an example of the recipe list screen P28. As shown in FIG. 28, on the recipe list screen P28, items such as a patient ID, a patient name, a medical department, a medicine name, and a deletion corresponding to the recipe information are displayed.

  Further, as shown in FIG. 28, a 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 development area A281, the control unit 11 expands the display area of the development area A281 as shown in FIG. Then, in the development area A281, various touch keys indicating contents operable on the recipe list screen P28 are displayed.

  By the way, also in the case of displaying the recipe list screen P28, the control unit 11 sets a predetermined number of preset predetermined numbers that can be displayed simultaneously on the recipe list screen P28, as in the case of displaying the recipe list screen P25. The upper system 70 is requested to transmit the recipe information. Then, the control unit 11 receives the predetermined number of pieces of the recipe information from the host system 70 and stores the recipe information 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 according to the operation of “previous data” or “next data” displayed in the development area A251. As described above, in order to allow the medicine weighing device 10 to acquire only the necessary recipe information from the host system 70, in the configuration in which the plurality of medicine weighing devices 10 are connected to the host system 70, the host system 70 Can execute an exclusive process of the recipe information or the prescription information.

  In the configuration in which the medicine weighing device 10 acquires the recipe information from the host system 70 in accordance with, for example, the dispensing system prescription IF sharing specification (NSIPS), the control unit 11 controls whether the user moves up and down with respect to the recipe list screen P28. In response to a flick operation in the direction, the recipe information displayed on the recipe list screen P28 can be changed by sliding.

  Then, when a 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 a selected state. To the effect. Thereafter, when a user performs a rightward or leftward flick operation on the touch panel 13 in a state where any of the recipe information is selected, the control unit 11 displays the details of the selected recipe information. The displayed prescription medicine information screen P30 is displayed on the touch panel 13. FIG. 30 is a diagram showing an example of the prescription medicine information screen P30. On the prescription drug information screen P30, information on the prescription drug included in the recipe information (drug name, usage, days, prescription amount, etc.) is displayed.

  Thereafter, the control unit 11 is displayed after the user performs a touch operation or an upward flick operation on the development area A281 of the recipe list screen P28 or the development area A301 of the prescription medicine 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 medicine information screen P30, the control unit 11 changes the display position of the prescription medicine whose weighing has been completed to a different display color to indicate this.

<Step S56>
In step S56, the control unit 11 determines whether the type of system linkage of the medicine 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 a user operation on the touch panel 13 from the data storage unit 15 or the host system 70. 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 a user operation on the touch panel 13 from the data storage unit 15 or the host system 70. . Here, when the type of the system interlock is “patient ID” or “voucher number” (Yes in S56), the control unit 11 shifts the processing to step S57, and proceeds to step S57. If it is not a “voucher ticket number” (No in S57), the process returns to step S51.

<Step S57>
In step S57, the control unit 11 inputs a patient ID when the type of system linkage is “patient ID”, and inputs a voucher number when the type of system linkage is “voucher number”. Input screen P31 is displayed on the touch panel 13. 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 prescription information corresponding to the patient ID from the prescription information stored in the data storage unit 15. Then, the control unit 11 causes the prescription list screen P25 to display prescription information corresponding to the patient ID. When the type of the system linkage 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.

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

  Hereinafter, another example of the generic drug use processing will be described with reference to FIG. 32. Note 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 host system 70, for example, in the drug weighing system 1. . Here, as shown in FIG. 33, the prescription information displayed on the prescription screen P23 contains a prescription medicine of “Gaster powder 10%”, and the barcode reader 17 displays “Gas dog powder 10”. The case where "%" is read as the contained medicine name will be described as an example.

<Step S61>
First, in step S61, the control unit 11 executes a process for selecting a change target to be changed to the stored medicine name read in step S3 from the prescription medicine 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 displays the prescription drug name selected by a user operation on the touch panel 13. Select as change target. If there is only one prescription drug name, the control unit 11 may automatically select the one prescription drug name as a change target.

<Step S62>
Next, in step S62, the control unit 11 determines whether or not the prescription information does not include change-impossible information indicating that the prescription medicine name selected in step S61 cannot be changed to a generic medicine. Judge. When the prescription information includes the non-changeable information (Yes in S62), the control unit 11 shifts the processing to step S63. On the other hand, when the change prohibition information is not included (No in S62), the control unit 11 shifts the processing to step S611 and executes the prescription medicine change processing (see FIG. 34) described later. The non-changeable information is added to the prescription information in the host system 70. It is also conceivable that the control unit 11 adds information in response to a user operation on the touch panel 13.

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

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

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

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

<Step S72>
In step S72, the control unit 11 changes the prescription medicine selected in step S61 to the generic medicine read as the contained medicine name, redisplays the prescription screen P23, and changes the prescription medicine. The process ends. FIG. 35 is a diagram illustrating an example of the prescription screen P23 after the prescription medicine has been changed to the generic medicine. As shown in FIG. 35, in the prescription screen P23 displayed in the step S72, “Gaster powder 10%” included as a prescription drug in the prescription information is changed to “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 changes the change history information (for example, the date and time of the change, the name of the pharmacist in charge of the change, and the content of the change). It is conceivable that the result is recorded as the weighing result. Thereby, the history of changing the prescription medicine to the generic medicine or the like can be easily confirmed later.

  In addition, in the step S72, the control unit 11 displays the medicine list screen P33 of the original medicine and the generic medicine corresponding to the contained medicine name on the touch panel 13 based on the generic medicine master. Of the embodiment. FIG. 36 is a view showing an example of the medicine list screen P33. As shown in FIG. 36, on the medicine list screen P33, a generic name (famotidine) of the medicine corresponding to the contained medicine name, and an innovator medicine and a generic medicine corresponding to the contained medicine name are displayed. In the medicine list screen P33, when a user performs a touch operation for selecting any of the displayed original medicine and the generic medicine, the display color of the display position of the selected medicine name is changed. The selection state is indicated. At the time of initial display of the medicine list screen P33, the contained medicine name read by the barcode reader 17 is in a selected state. Then, when the enter key K331 is operated in a state where any one of the generic drugs is 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 of the medicine list screen P33 is operated, the control unit 11 cancels the registration of the generic medicine and ends the prescription medicine change processing.

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

<Step S81>
First, in step S81, the control unit 11 causes the touch panel 13 to display that the stored medicine name is not registered as the generic medicine, and determines whether or not to register the medicine name as the generic medicine. A confirmation message (for example, see FIG. 9C) is displayed.

<Step S82>
In step S82, when the control unit 11 determines that the operation of registering the contained medicine name as the generic drug has been performed on the touch panel 13 (Yes in S82), the process proceeds to step S83. Migrate. In addition, the control part 11 will complete | finish the registration process of the said generic drug, when the operation | movement of not registering the said contained medicine name as the said generic drug is performed on the said touchscreen 13 (No side of S82).

<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 name of the innovator drug registered in the drug master, the control unit 11 associates the name of the innovator drug with the name of the innovator drug. The maintenance screen P38 for registering a product or drug is displayed. On the other hand, when the prescription drug name selected in the 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 subsequently assigned to the generic drug master. Specify based on. Then, the maintenance screen P38 for registering the generic drug name in association with the identified generic drug name is displayed.

  FIG. 38 is a view showing an example of the maintenance screen P38. As shown in FIG. 38, the name of the original drug and the registered generic drug corresponding to the original drug are displayed on the maintenance screen P38, and the name of the contained drug is added as a generic drug of the original drug. The displayed status is displayed. For example, on the maintenance screen P38 shown in FIG. 38, when “Gasdog powder 10%” is not registered as a generic drug of “Gaster powder 10%”, which is the original drug, the “Gasdog powder” is used as the stored medicine name. 9 shows a display example when “dispersion 10%” is read.

<Steps S84 to S85>
Then, in steps S84 to S85, the control unit 11 waits for an operation of the registration key K381 or the end key K382 on the maintenance screen P38 (No in S84 and S85). Here, when determining that the registration key K381 has been operated (Yes in S84), the control unit 11 shifts the processing to step S86. On the other hand, when determining that the end key K382 has been operated (Yes in S85), the control unit 11 terminates 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 medicine as the generic medicine in the generic medicine master, and sends a confirmation message for confirming whether to change to the generic medicine registered on the maintenance screen P38. Display.

<Step S87>
Then, when an operation to change to the generic drug is performed (Yes in S87), the control unit 11 shifts the processing 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 as in step S72. On the other hand, when an operation not to change to the generic drug is performed (No in 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 medicine weighing device 10, when the power of the medicine weighing device 10 is turned on and the medicine weighing device 10 is started, a start process preset by the control unit 11 is executed. In addition, when the medicine weighing device 10 returns from the power saving mode to the normal mode, or when the date update process is executed in the medicine weighing device 10, the control unit 11 executes the start-up process. Is also conceivable. Hereinafter, an example of the procedure of the activation process will be described with reference to FIG.

<Step S91>
When the power of the medicine weighing device 10 is turned on and the medicine 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 perform the control. The control of the medicine weighing device 10 by the unit 11 is enabled.

<Steps S92 to S94>
In step 92, the control unit 11 checks whether the data storage unit 15 is connected to the USB port 16. When the connection of the data storage unit 15 is confirmed in step S93 (Yes in S93), the control unit 11 shifts the processing to step S931, and the connection of the data storage unit 15 is confirmed. If not (No in S93), the process proceeds to step S94. In step S94, the control unit 11 operates the medicine weighing device 10 as an electronic balance by activating the weighing unit application 116 in the SD card 112. Thereafter, in step S95, when the power OFF operation on the touch panel 13 is performed (Yes in S95), the control unit 11 executes shutdown processing of the chemical weighing device 10 in subsequent step S96 to turn off the power. Turn off.

<Steps S931 to S932>
On the other hand, if the connection of the data storage unit 15 is confirmed, the control unit 11 executes a preset update process in the subsequent step S931, and then activates the medicine weighing program 154 (S932). Is transferred to step S95.

  Specifically, in the updating process, the control unit 11 determines whether the medicine weighing program 154 stored in the data storage unit 15 is the latest. The determination as to whether or not the medicine weighing program is the latest is performed by acquiring update information from the Internet or the like via the host system 70 or the network N, for example. Here, when it is determined that the medicine weighing program 154 is not the latest, the control unit 11 downloads the latest medicine weighing program 154 and updates the medicine weighing program 154 of the data storage unit 15.

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

  Thereafter, the control unit 11 backs up various data such as the prescription information, the weighing result, various master information (such as a generic drug master), 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) using the SQL language. . Therefore, the control unit 11 stores the table data such as the prescription information, the weighing result, various types of master information, and system setting information stored in a database format into the database using a backup function of the database management system. The data is output as a dump file 156 and stored in the data storage unit 15. At this time, when the update process ends normally, the control unit 11 leaves only the latest database dump file 156 or only a preset number of the database dump files 156, and stores the database dump file 156 before that. 156 is deleted. The backup destination by the control unit 11 is not limited to the data storage unit 15 but may be, for example, the medicine packaging device 20, the host system 70, or a server device on the Internet. As described above, in the medicine weighing device 10, since the backup is performed at the time of startup, even if an abnormality occurs in the medicine weighing device 10 and the database is damaged, etc., at least the medicine weighing is performed. The database can be restored until the device 10 is started.

[Modification of Chemical Weighing Process]
And also in the medicine weighing system 2 configured as described above, in the medicine weighing device 10, the control unit 11 executes the same medicine weighing processing as the medicine weighing processing (see FIG. 5). However, as described above, in the medicine weighing system 2, the method of reading the prescription information in the step S1 executed by the medicine weighing device 10 is different. Specifically, the control unit 11 can receive the prescription information from the host system 70 in addition to reading the prescription information using the barcode reader 17. That is, in the step S1 of the medicine weighing process, the control unit 11 determines whether any of the prescription information received from the host system 70 and stored in the data storage unit 15 is in accordance with a user operation on the touch panel 13. Also, when the prescription information is selected, it is determined that the prescription information has been input, and the process proceeds to the step S2. Further, when the type of the system interlock is set to “sequential”, the control unit 11 sorts the prescription information acquired from the host system 70 and stored in the data storage unit 15 in chronological order. The process also shifts to step S2 when reading automatically.

  Here, when the recipe to be weighed by the medicine weighing device 10 is determined in the step S2, the control unit 11 executes an automatic numbering process for setting a tray number corresponding to the recipe. The tray number is a four-digit value that is automatically set by the control unit 11 in the medicine weighing device 10 and is set in advance in the medicine weighing system 2 so as not to be duplicated for each of the medicine weighing devices 10. Is set within the range specified. For example, as shown in FIG. 17, when four medicine weighing devices 10 are connected to the medicine weighing system 2, “0000” to “1000”, “1001” to Tray numbers from “2000”, “2001” to “3000”, and “3001” to “4000” are assigned in advance. Also, the tray number is a number assigned to each recipe, and even when a plurality of prescription drugs are included in the recipe, the tray numbers are numbered as numbers common to 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 medicine packaging devices 20. Specifically, in the shared folder, only the tray number for which the packaging process in the medicine packaging device 20 has not been completed remains, and the tray number for which the packaging process has been completed is the same as the tray number of the medicine packaging device 20. Is erased by the control unit 21. On the other hand, when the tray number is not stored in the shared folder, the controller 11 of the medicine weighing device 10 stores the tray number in the shared folder of the medicine packaging device 20. In addition, the control unit 11 adds 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. This allows the medicine packaging device 20 to read the recipe information from the data storage unit 25 based on the tray number. The timing at which the control unit 11 records the correspondence between the recipe information and the tray number in the data storage unit 25 is the timing at which the RFID reader / writer 14 records the tray number on the RFID tag 31. You may. The control unit 11 may store the recipe information in the data storage unit 25 after the tray number is associated with the recipe information.

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

  Further, in step S2, after storing the tray number in the shared folder, the control unit 11 determines in which of the medicine packaging apparatuses 20 the packaging process of the recipe corresponding to the tray number is performed. Is displayed on the touch panel 13. FIG. 40 is a diagram showing an example of the machine selection screen P40. As shown in FIG. 40, on the device selection screen P40, a device selection key K401 for selecting a device number preset for each of the medicine packaging apparatuses 20 is displayed. The control unit 11 displays a preset number of machine numbers in a pull-down menu according 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. Note that the number of machine numbers displayed in the pull-down menu is considered to be the number of the medicine packaging devices 20 connected to the medicine weighing system 2 or the maximum number connectable to the medicine 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 medicine packaging apparatus 20 is displayed. The control unit 11 displays a preset hopper number in a pull-down menu according to the 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, the pull-down menu includes “A” indicating the hopper 25A provided in the medicine packaging device 20, “B” indicating the hopper 25B, or “AB” indicating that any of the hoppers 25A and 25B may be used. Is displayed. In addition, the control unit 11 changes the display of the pull-down menu in the hopper selection key K402 according to the number of hoppers provided in the medicine packaging apparatus 20 corresponding to the unit number selected by the unit selection key K401. It is also possible to do.

  Note that, 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 has been described as an example, but the invention is not limited thereto. . Specifically, in the step S2, the control unit 11 displays a number selection screen on which only the number selection key K401 is displayed and inputs the number, and then weighs the prescription medicine in the medicine weighing device 10. It is conceivable to display a hopper selection screen on which only the hopper selection key K402 is displayed and to input the hopper number when the operation is completed. This makes it possible to select the hopper for each prescription drug when one recipe contains a plurality of prescription drugs. Further, the trouble of inputting the unit number for each of the prescription drugs is also omitted.

  Then, in a process corresponding to the step S9 (see FIG. 5) of the medicine weighing process, the control unit 11 uses the RFID reader / writer 14 to store the tray number, the machine number, and the hopper number in the RFID tag 31. Write to. Thereby, when the dispensing sheet 30 provided with the RFID 31 is set in the medicine packaging device 20, the number of the unit stored in the RFID 31 by the control unit 21 in the medicine packaging device 20 is the medicine packaging number. It can be checked whether or not it matches the device number of the device 20. Further, in the medicine packaging apparatus 20, the control unit 21 can automatically set a medicine introduction destination of the dispensing sheet 30 according to the hopper number. Then, in the medicine packaging apparatus 20, the recipe information stored in the data storage unit 26 in association with the tray number is read from the data storage unit 26 by the control unit 21. In addition, 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 transmits the machine number from the shared folder in accordance with the tray number. And reading the hopper number.

  Further, in the medicine weighing device 10, the control unit 11 can write the tray number, the machine number, and the hopper number into the RFID tag 31 in a recipe unit instead of a prescription medicine unit. . In this case, when the weighing of the plurality of prescription medicines included in one recipe is completed, the control unit 11 shifts the “registration” key on the prescription screen P23 (see FIG. 23) to an operable state and , A guidance such as “Please set the medicine tray” is displayed on the touch panel 13. When the “registration” key is operated on the prescription screen P23, the control unit 11 stores the tray number, the machine number, and the hopper number corresponding to the recipe in the RFID tag by the RFID reader / writer 14. Write to 31.

[Package input processing]
On the other hand, in the medicine packaging apparatus 20, the control unit 21 reads the tray number from the RFID tag 31 of the medicine sheet 30, and stores the recipe information corresponding to the tray number and the weighing result as data to be packaged. Is executed.

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

  In the packaging input processing, 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 a packaging input screen P41 displayed on the touch panel 23. Here, FIGS. 41 and 42 are diagrams 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 medicines included in the recipe information is displayed. In addition, the package input screen P41 displays a list of prescription drugs already read from the RFID tag 31 by the RFID reader / writer 24 among prescription drugs included in the recipe information, the weighing result of each of the prescription drugs, It includes a display area A412 in which a packaging pattern, the hopper number, and the like are displayed. Accordingly, the user can easily grasp the number of medicines that are currently insufficient to start the operation of packaging the recipe in the medicine packaging apparatus 20. Further, by comparing the prescription with the list of prescription medicines displayed on the packaging input screen P41, it is possible to grasp the name of the medicine that is currently lacking to start the packaging operation of the recipe information. is there. Then, as shown in FIG. 42, when all the prescription medicines included in the recipe information displayed on the packaging input screen P42 are read, the control unit 21 issues an issue key for starting a packaging operation. K413 is changed to an operable state. Thereafter, the control unit 21 starts a packaging operation for the recipe information in response to the operation of the issue key K413.

  Further, when the control unit 21 reads the tray number from the RFID tag 31 by the RFID reader / writer 24, a list of prescription drugs included in the recipe information corresponding to the tray number is input in the package. Displaying on the screen P41 is also conceivable. Then, the control unit 21 displays, in the list of drug names displayed on the package input screen P41, a character (“「 ”or“ 示 す ”) indicating whether or not information on each of the prescription drugs has been read from the RFID tag 31. It is conceivable to display confirmation information such as "x") or an image. Thereby, the user can easily grasp the number of medicines currently lacking and the medicine name by checking the packaging input screen P41. Note that whether or not each of the prescription drugs is read on the packaging input screen P41 may be represented by, for example, changing the display color (the presence or absence of gray-out) of the display position of each of the prescription drugs.

  Incidentally, a configuration in which a plurality of the prescription drugs included in the recipe information are placed on one dispensing sheet 30 and the dispensing into the hopper 25A or the hopper 25B in the unit of the recipe may be considered. In this case, at the time when the tray number is read from the RFID tag 31 of the dispensing sheet 30, the control unit 21 starts the packaging operation relating to the recipe information without displaying the packaging input screen P41. Display the monitor screen for

[Detection printing process]
Further, in the medicine packaging device 20, the control unit 21 executes a medicine inspection printing process for printing out the weighing result output from the medicine weighing device 10 on the packing paper using the printing unit 27. It is possible to do.

  Specifically, in the medicine printing process, the control unit 21 prints predetermined medicine information at the beginning or end of a series of wrapping papers output by the packing operation of the medicine wrapping device 20. Add the added packaging paper and output. The content of the drug detection information can be changed by the control unit 21 in accordance with a user operation on the touch panel 23 in an initial setting or the like in the drug packaging device 20.

  Here, FIGS. 43 and 44 are diagrams showing an example of a print image of the drug detection information. The drug information shown in FIG. 43 includes the date (November 26, 2007), the patient's name (Taro Yuyama), the voucher number (5678), the number of days (3), and the total weight of the medicine package (369.0000 g). included. The total weight of the medicine package is a total value of the total weight of the packaging paper used for the packaging in 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 chemical weighing device 10 and the weighing result output from the chemical weighing device 10, It is possible to calculate the total weight of the medicine package. In the medicine weighing device 10, the controller 11 calculates a value obtained by multiplying the number of wrappers used for wrapping in the recipe unit by a preset weight per wrapper. The total weight of the packaging paper is calculated 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 first setting key K235 (see FIG. 24) for setting the type of the packaging paper. The determination can be made according to the combination of the material and the length. In this way, since the medicine detection information is printed on the packaging paper, it is possible to audit the packaging operation in the recipe unit without the user referring to the prescription, for example. For example, the user separates the packaging paper on which the medicine detection information is printed from a series of packaging papers, and weighs the remaining total weight of the packaging paper with the chemical weighing device 10 or another electronic balance or the like. . Then, the user performs the inspection by comparing the medicine packaged total weight printed as the medicine detection information with an actual weighed value.

  Further, the drug detection information shown in FIG. 44 includes a drug name, a packaging pattern (11111111), an expiration date (November 26, 2007), a lot number, an actually measured value (369.0000 g), and a theoretical value (369.0000 g). ). The packaging pattern is information for indicating the dosage time (morning, noon, evening, etc.) determined by the recipe information by the positions of “1” and “0” in a plurality of preset digits. The measured value is the total weight of the prescription medicine actually weighed in the medicine weighing device 10 and is information included in the weighing result output from the medicine weighing device 10. The theoretical value is the theoretical total weight of the prescription medicine calculated based on the daily amount, usage, days, and the like included in the recipe information. For example, the control unit 21 subtracts the weight of the prescribed drug that is not to be taken within the time of taking from the maximum weight obtained by multiplying the value obtained by multiplying the daily amount and the number of times of taking determined by the usage method by the number of days. Thus, the theoretical value is calculated. Specifically, when the usage is set to three times, morning, noon, and evening, and when the starting time and the ending time are both daytime, the weight of the medicine for the first morning and the last day are taken. 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 inspect the packaging of the recipe unit using the medicine weighing device 10 or another electronic balance while referring to the packaging paper on which the medicine detection information is printed. it can.

[Summary of Embodiment]
A medicine weighing device according to the present invention includes weighing means, prescription information reading means, stored medicine information reading means, and control means. The weighing means weighs a medicine. The prescription information reading means reads, from the prescription, prescription information including prescription drug identification information for identifying one or a plurality of prescription drugs recorded on the prescription. The stored medicine information reading means reads, from the medicine container, stored medicine information including stored medicine identification information for identifying the stored medicine recorded in the medicine container. The control means, when the stored medicine read by the stored medicine information reading means corresponds to any of the prescription medicines read by the prescription information reading means, selects the prescription medicine as a weighing target, A weighing screen on which the prescription medicine is weighed is displayed on the display means. 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 each meal, etc.). The prescription medicine identification information and the contained medicine identification information are information such as a medicine name or a medicine code capable of specifying the type of medicine.

  According to the present invention, when the contained medicine corresponds to any of the prescribed medicines, the prescribed medicine is automatically selected as a weighing target and displayed on the weighing screen. That is, according to the present invention, the user only needs to read the contained medicine information of the medicine container by the contained medicine information reading means, and in the medicine weighing device, check the prescribed medicine and the contained medicine, Selection of a prescription medicine to be weighed in the prescription information can be realized at the same time. Accordingly, when a plurality of prescription drugs are included in the prescription information, an operation for selecting a prescription drug to be weighed can be omitted, and dispensing efficiency by a user such as a doctor or a pharmacist can be increased. Can be. Therefore, according to the present invention, accurate medicine weighing according to a prescription can be easily performed without cooperation with a host system such as a dispensing support system.

  Here, a configuration is conceivable in which the medicine weighing device includes a code reading unit that reads information from a barcode 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 reads the bar information recorded on the medicine container. It is conceivable that the contained medicine information is read from the code or the two-dimensional code by the code reading means. For example, in the configuration including the code reading unit, the user can accurately and easily follow the prescription by causing the code reading unit to sequentially read the two-dimensional code of the prescription and the barcode of a medicine container (eg, a medicine bottle). Drug weighing can be performed. In particular, the user, in the medicine weighing device, performs the collation of the contained medicine and the prescription medicine and the selection of the medicine to be weighed only by the operation of reading the barcode recorded in the medicine container by the code reading means. Can be realized. In addition, since the code reading unit can be shared by the prescription information reading unit and the stored medicine information reading unit, a new configuration is provided in the conventional configuration including the stored medicine information reading unit and the code reading unit. No additional elements are required. The barcode is a one-dimensional code having information only in the horizontal direction, and is, for example, a JAN code, RSS, or the like. The two-dimensional code has information in the horizontal and vertical directions, and is, for example, a QR code (registered trademark). Further, the prescription information reading means and the contained medicine information reading means may read information directly from the prescription or the medicine container using, for example, a character recognition technique or an image recognition technique.

  Further, a configuration in which the medicine weighing device further includes a code reading unit that reads information from a barcode or a two-dimensional code, and a wireless reading unit that reads information from an information recording medium by wireless communication is also conceivable. In this case, the prescription reading unit reads the prescription information from the barcode or the two-dimensional code recorded on the prescription by the code reading unit, and the stored medicine information reading unit includes an information recording device provided on the medicine container. It is conceivable to read the stored medicine information from a medium by the wireless reading means.
