Description

  The present invention relates to a drug weighing device for weighing and auditing drugs such as powders and liquids in hospitals and dispensing pharmacies.

  2. Description of the Related Art Conventionally, when dispensing powders or the like, devices are known that not only weigh the corresponding drug according to a prescription, but also audit whether the weighed value is appropriate as a normal dose (for example, Patent Documents 1 and 2).

JP 2004-20884 A JP 2002-282341 A

  However, the conventional apparatus requires an audit system (for example, a notebook personal computer) such as a display means and a control means in addition to the weighing apparatus, which causes a pressure on the dispensing space. Further, the weighing device and the audit system are connected by a communication line, and after the result measured by the weighing device is determined, the result is transmitted to the audit system. For this reason, it is necessary to pay attention to whether or not data transmission is performed appropriately (for example, communication failure). Furthermore, since the weighing value and the audit check result are displayed on different devices, it is necessary for the dispenser to proceed with dispensing while comparing both, and there is a problem that workability is poor. In addition, since it is prohibited by the weighing method to output an unstable weighing value from the balance to the external device, there is a slight time lag between the display of the weighing value on the weighing device and the display on the display means. This is unavoidable and is troublesome for the dispenser. In addition, the audit check result displayed on the display means may be overlooked. Furthermore, there is also a problem in that dispensing cannot be performed unless all weighing conditions are entered during an audit check.

  Therefore, the present invention has not only weighing but also an auditing function, and is a compact configuration that can display the weighing value and the audit result on the same screen, and can perform an audit according to the input condition of the weighing condition. It is an object to provide a possible chemical weighing device.

As a means for solving the above problems, the present invention provides:
Chemical weighing device,
In the device body,
Weighing means for weighing the drug to be dispensed,
Display means for displaying a weighing value and weighing conditions;
Input means for inputting the weighing conditions;

  Embodiments according to the present invention will be described below with reference to the accompanying drawings.

<Configuration>
FIG. 1 shows a chemical weighing apparatus according to this embodiment. This chemical weighing apparatus generally has a configuration in which a weighing unit 2, a display unit 3, a storage unit 4, and a control unit 5 are provided in an apparatus main body 1, and a printer 6 and a barcode reader 7 are connected.

  The apparatus main body 1 is composed of a box-shaped housing, and a windshield case 8 can be placed on the upper surface of the rear half.

  The windshield case 8 is for eliminating the influence of the surrounding air flow on the chemicals placed on the balance table 2a. As shown in FIG. 1A, the windshield case 8 includes a quadrangular frame body 9 and a lid body 10 for opening and closing the upper opening thereof. The front portion of the frame body 9 is removed except for the lower end portion, so that it is easy to put in and out the medicine or the tray on which the medicine is placed from the front. The side surface of the frame body 9 is formed with a low front side so that medicines and the like can be taken in and out from the side. In addition, a protrusion 9b is provided on the extended portion 9a formed at the lower center portion of the side surface so as to engage with a hole (not shown) formed in the upper surface of the device main body 1, thereby On the other hand, the windshield case 8 can be positioned. As shown in FIG. 1B, a bearing 90 is provided at the upper rear end portion of the frame body 9. The bearing 90 is a state in which the lid body 10 is opened with respect to the frame body 9 by supporting the spindle 10a of the lid body 10 so as to be rotatable and the diagonally supporting the spindle 10a. 2nd support part 90b maintained in this. The support shaft 10a is formed with plate-like portions 10b that project obliquely at both ends, is rotatably supported by the first support portion 90a of the bearing 90, and the plate-like portion 10b is engaged with the second support portion 90b of the bearing 90. By joining, the cover body 10 is maintained in an inclined state. Then, by supporting the plate-like portion 10b on the second support portion 90b of the bearing 90, the lid body 10 can be maintained in a half-open state inclined with respect to the frame body 9. It is possible to weigh while eliminating the influence of the air flow. Further, when the influence of the air flow cannot be eliminated even in the half-open state, it may be weighed in the closed state.

  A detachable cover 1a is provided on the rear upper surface of the apparatus main body 1. When this cover 1a is removed, it becomes a mounting chamber in which the storage medium 11 constituting the storage means according to the present invention can be attached and detached. Various storage media 11 such as a USB memory, a memory card, and a disk can be used. Here, a USB memory is used and is attached to and detached from the USB port exposed in the mounting chamber. Further, a detachable cover (not shown) is provided on the back surface of the apparatus main body 1, and when this cover is removed, it becomes a space where the battery cell can be attached and detached. This battery cell is for supplying power to be used when the power of the internal clock that is the basis of weighing time recording is turned off. As described above, the recording medium 11 and the battery battery can be exchanged without disassembling the apparatus main body 1 (no problem in the measurement method). Note that the power supply from the battery cell is switched to an AC power source by turning on a switch (not shown) provided on the side surface of the apparatus main body 1 so that consumption is suppressed. Also, if the remaining battery power is displayed, and if the remaining battery power is low, the buzzer or other means will notify the time of the internal clock due to battery exhaustion, resulting in trouble with the recorded data. Can be prevented.

  The storage medium 11 stores various types of information other than information stored in the storage unit 4 described later. Here, programs relating to the audit function, drug data, and the like are stored.

  Examples of the drug data include data obtained by extracting only data related to a drug (adopted drug) handled by a dispensing pharmacy using a drug weighing device from a drug master (mother master) stored in a server. Here, chemical code, chemical name, JAN code, drug bottle (lot number, expiration date, inventory management, etc.), classification (dosage form: powder, liquid medicine, topical medicine), specific gravity, chemical type (ordinary medicine, poisonous medicine) , Narcotics, powerful drugs, antipsychotics, clinical trials), formulation changes, excipients, precautions, etc. The JAN code is a code (bar code) for identifying a medicine attached to a medicine box supplied from a pharmaceutical manufacturer. These data can be automatically taken in from the mother master, and can also be registered from the display unit 3 described later.

  The medicine data to be stored in the storage medium 11 may be obtained by extracting necessary data from the mother master and creating a medicine master (submaster) for the medicine handled by the medicine weighing device in advance. The registration of data to the mother master or submaster can be performed as follows.

  That is, the medicine master registration screen shown in FIG. On that screen, call the drug code and drug name from the drug master (you may enter them manually). Then, a JAN code and a medicine bottle code associated with these are input. The medicine bottle code is a code (bar code) attached to a medicine bottle accommodated when the medicine accommodated in the medicine box is subdivided. In this case, one or more JAN codes and drug bottle codes can be registered in correspondence with the drug code and the drug name. However, duplicate registration of JAN code and vial code between different drugs is not possible.

  By the way, if the item “medicine name” is clicked on, the item is switched to the item “medicine sound”, and a sound such as a warning sound can be associated with reference to the sound file. Thereby, when determining a medicine at the time of dispensing, it is possible to read out the medicine name or output a warning sound to the caution medicine by the speaker 12 described later.

  In addition, if a detail button is clicked, the detail registration screen of the medicine master shown in FIG. 18 is displayed. On the detailed registration screen, it is possible to input the classification, specific gravity, chemical type, change in composition, and shaping chemical (unit, weighing). Enter the dosage form (powder, liquid, external) in the Category field. Enter the specific gravity of the drug in the specific gravity field. In the drug type column, select and input from normal drugs, poison drugs, narcotics, powerful drugs, psychotropic drugs, and investigational drugs. In the blending change column, select from neutral, acidic, alkaline, or single and input. In the excipient, enter the excipient normally used.

  In addition, if the item “medicine bottle” is clicked, the medicine bottle registration screen shown in FIG. 19 is displayed. On the medicine bottle registration screen, the container weight, inventory quantity, medicine lot number, and expiration date can be registered.

  In the classification data, in the case of powder, it is possible to set whether or not to check with a single dose (for example, the weight of the powder taken once after a meal). It is also possible to set to permit dispensing of powder only, or to dispense only liquid medicine and external medicine, or to permit or disallow simultaneous dispensing of powder medicine, liquid medicine and external medicine. It is also possible to set a warning when dispensing is performed under conditions that are not permitted.

  In the data of the above-mentioned shaping medicine (molding data), the shaping processing can be executed when the prescription amount per day or per package does not satisfy the reference amount. As the shaping method, three patterns of “by age”, “reference amount”, and “fixed amount” are set. In the “age-specific” shaping method, the amount of shaping according to age is determined in advance. In the “reference amount” shaping method, the shaping amount is calculated so that the prescription amount becomes the reference amount. In the “fixed amount” shaping method, the amount of excipient mixed for each drug is set to a constant value. Accordingly, it is only necessary to weigh a certain amount of the excipient, which makes it easier to handle than the “reference amount” shaping method. In the shaping data, it is possible to set whether or not the shaping process is automatically performed. In addition, shaping means mixing excipients such as lactose, starch, glucose, etc. in order to increase the amount of chemicals, give a certain shape, and make it easy to use.

  A speaker 12 is provided in the front part of the apparatus main body 1. The speaker 12 is used to output a warning sound or the like as necessary.

  The weighing unit 2 constitutes a weighing means according to the present invention, and includes a balance unit 13 as shown in FIG. The balance unit 13 includes a parallel circuit 14, a force coil 15, a current / voltage conversion circuit 16, and an A / D conversion circuit 17. The balance unit 13 converts the weight of the medicine placed on the balance table 2 a into a digital signal, and the main board 18. Output via serial communication.

  The display unit 3 is composed of a touch panel, and has both functions of a display unit and an input unit according to the present invention. The display unit 3 displays a dispenser input screen shown in FIG. 5 as an initial screen after activation. The dispenser input screen is configured such that a list of registered dispensers is displayed and can be selected from the list. The dispenser can open a registration screen (not shown) and newly register, and the order of displaying the list can also be set in the order of registration or ascending order of dispenser names. Then, when a dispenser is input on the dispenser input screen, the screen is switched to the audit work screen shown in FIG.

  However, it is preferable to display the password input screen shown in FIG. 7 as the initial screen after startup and to switch to the audit work screen only when an appropriate password is input. This restricts the use of unauthorized third parties and identifies who is the dispenser performing the auditing work.

  The audit operation screen has various buttons for entering the weighing conditions at the top, that is, “Dispenser”, “Prescription number”, “Days”, “Fraction”, “Age”, “Weight” buttons, and “Menu” "Button is displayed. In the central part of the screen, a list of medicines and chemicals to be audited (dispensation target medicines) consisting of medicine names and measured amounts (weights) is displayed. At the bottom of the screen, “Register”, “Print”, and “Cancel” buttons are displayed. However, the “input” button is not displayed, and is switched to a display state when the barcode reader 7 is out of order as will be described later.

  The dispenser input screen is switched to the weighing screen shown in FIG. 8 when at least the dispenser is input and the barcode attached to the medicine bottle is read by the barcode reader 7. However, if the barcode reader 7 is out of order, the “input” button is displayed on the auditing operation screen shown in FIG. 6 without switching to the weighing screen, and the drug code number can be manually entered.

  The weighing screen displays weighing information and audit information input by operating each button at the top. Weighing information includes drug name (1: circled characters in drawings), check method (2: circled characters in drawings), age (3: circled characters in drawings), normal dose unit (4: circled characters in drawings) ), Normal dose display form (5: circled letters in the drawing), normal dose (6: circled letters in the drawing), and notes (7: circled letters in the drawing). Below these items, “stability”, “CAL”, and “RANGE” buttons are displayed. Below that, there is a weighing frame (12: circled letters in the drawing) for displaying the weighing result. Is displayed. A target value is displayed above the weighing frame, and it is shown how many grams should be finally weighed. A weighing bar indicating the weighing state is displayed below the weighing frame. The weighing bar has a zero point at the left end (the zero point is corrected taking into account the weight of the tray to be placed), and when a drug to be weighed is placed on the weighing platform 2a, the weighing bar moves from the left end to the right end. The measured bar is displayed in a color different from that of the weighing bar up to a position corresponding to the weighing value. Therefore, the dispenser can proceed with the work while sensuously grasping the additional amount of the medicine to be weighed. On the left side of the weighing frame is a range from the top (8: circled characters in the drawing), tracking on / off (9: circled characters in the drawing), stability mark (10: circled characters in the drawing), zero display ( 11: Circled characters in the drawing) are displayed. The right side of the weighing frame is a weighing unit (13: letters in circles in the drawing). Further, buttons “Tare”, “Expand”, “Cancel” (14: circled characters in the drawing), and “Determination” (15: circled characters in the drawing) are displayed below the weighing frame.

  The storage unit 4 stores weighing-related data and programs that cannot be changed. Here, a CF (Compact Flash) card is used for the storage unit 4.

  The control unit 5 constitutes a control unit according to the present invention, and includes a main board 18 as shown in FIG. A CPU 19, a memory circuit 20, a communication control circuit 21, an audio circuit 22, and a display circuit 23 are mounted on the main board 18, and the storage medium 11 is detachable. As will be described later, the control unit 5 calls and executes programs from the storage unit 4 and the storage medium 11 and performs display control of the display unit 3 and the like.

  The printer 6 is for printing audit results and the like.

  The bar code reader 7 is used to read a bar code indicating the type of medicine attached to the medicine bottle. Based on the read barcode, the medicine data stored in the storage medium 11 is referred to and necessary data is read out from the medicine data.

<Operation>
Next, operation | movement of the chemical | medical agent weighing apparatus provided with the said structure is demonstrated according to the flowchart of FIG.

  The dispenser input screen is displayed upon activation (step S1), and when a dispenser to be dispensed is selected from a list of dispensers registered in advance in the dispenser master (step S2), the screen is switched to the audit operation screen. (Step S3).

  However, it is preferable that the password input screen is displayed upon activation in step S1, and when an appropriate password is input in step S2, the screen is switched to the audit operation screen in step S3.

  On the audit work screen, various buttons are displayed at the top, and each button can be touch-operated to switch to the corresponding screen and input the corresponding item. Here, it is possible to perform each process of dispenser input, prescription number input, date input, number of days input, fraction input, age input, weight input, and maintenance. Moreover, about the target chemical | medical agent of weighing, it displays as a list | wrist (medicine list) of the chemical | medical agent name and target value (or measured value). Furthermore, it is possible to perform weighing of an arbitrary chemical by operating the scale single button.

  When the dispenser button is touch-operated, it is possible to display a dispenser list and perform dispenser input (including change of dispenser). However, as described above, when the screen is switched to the audit operation screen by inputting the password on the password input screen, the name of the dispenser is automatically displayed.

  When the prescription number button is touched, a processing data selection screen is displayed. Here, when the “sequential” button is touch-operated, the oldest of the prescription data input is extracted. In addition, when the “patient ID” button is touch-operated, prescription data can be extracted in ascending order (or descending order) of identification numbers (ID numbers) assigned to each patient. When the “exchange ticket number” button is touch-operated, prescription data can be extracted based on the number (exchange ticket number) given to the medicine exchange ticket handed to each patient. When the “prescription number” button is touched, prescription data can be extracted based on the number automatically assigned to the prescription. When the “unprocessed list” button is touched, a list of prescriptions that have not been audited is displayed. Note that the prescription number can be input directly by operating the numeric keypad (displayed on the screen) without using the prescription number button.

  When the date button is touched, it is possible to input a date (in this case, change the date). Unless the date is changed by operating the date button, today's date and time are displayed on the date button of the audit work screen.

  When the number of days button is touch-operated, it is possible to input the number of prescription days, that is, how many days the medicine is to be prescribed.

  When the fraction button is touch-operated, it is possible to input the number of doses per day.

  When the age button is touched, the patient's age can be input. As an input method, it is possible to directly input the age, or input the date of birth in the Western calendar or the Japanese calendar, and calculate the age from the current date.

  When the weight button is touched, the patient's weight can be input.

  When the menu button is touched, a pull-down menu is displayed as shown in FIG. The pull-down menu includes master maintenance, filling, form, update, setting, maintenance, system linkage, and OFF.

  When filling is clicked, a filling operation screen shown in FIG. 21 is displayed. The filling operation screen includes columns for a dispenser, a medicine, a medicine bottle, an original bottle, a lot number, an expiration date, a filling amount, and an inventory amount. When the JAN code attached to the medicine box or the medicine bottle code attached to the medicine bottle is read by the barcode reader 7 in the medicine column, the name of the medicine read from the medicine master is displayed. The lot number, expiration date, and filling amount fields are used for inventory management. In this case, in addition to automatically taking in the filling amount from the weighing value, it is also possible to manually enter a numerical value.

  When the setting is clicked, a pull-down menu including dispensing setting, print setting, sound setting, and dose input is displayed.

  When the dispensing setting is clicked, it switches to the dispensing setting screen so that various settings can be made. Here, by providing four buttons of settings 1 to 4, a large number of settings can be performed on a narrow screen. For example, if setting 1 is operated, it is possible to set whether or not the shaping process is performed, whether or not the liquid medicine can be handled, and the like. Further, if the setting 2 is operated, it is possible to set a display form when the days button is operated. Thus, when the number of days button is clicked, the number of days selection screen shown in FIG. 9 is displayed and the number of days can be easily selected. With this setting, it is possible to display an easily selectable display by operating the days button on the auditing operation screen described later. Further, if setting 3 is operated, setting of attribute clear, target value display color and the like can be performed.

  In the sound setting, it is possible to freely set the sound output when each screen is opened or each button is clicked. With respect to important contents, for example, error information, if the contents are specifically notified by voice, it is possible to effectively prevent the occurrence of an audit error. Further, an audio file may be associated with each medicine stored in the master file, and the corresponding medicine name may be read out at the time of weighing.

  When the “dose input” is clicked, the display is changed to “no dose input”, and the display is switched every time the click is performed. When “With Dose Input” is selected, if the daily dose and the number of prescription days are entered, the entered daily dose is registered in the medicine master. It is judged whether or not it is within the appropriate daily amount range defined by Furthermore, when the fraction (the number of times of taking a day) is input, it is determined whether or not the dose is within the appropriate single dose range defined by the upper and lower limits of one normal dose. If it is within the proper range, the screen is switched to the weighing confirmation screen. If the medicine weighing device is connected to the network, the daily amount and the number of prescription days may be determined by communicating with the server and reading the prescription data.

  In addition, the name of the medicine to be dispensed and its dose are displayed in a list on the audit work screen based on the prescription data (prescription number.) Selected by operating the prescription number button. The dose is the prescription amount of the medicine described in the prescription. For example, when prescribing 2 g of A medicine per prescription for one week, 14 g is displayed in the dose column. When the item “target value” is clicked, the display content is changed to “actual value” and the weight per prescription (2 g in the above example) is displayed. If the dose is displayed, change the background color. Here, the background color is green. Thereby, the dispenser can easily recognize at a glance what the displayed weight relates to. Therefore, it is possible to perform display that is easy to see and is not mistaken in spite of the limited narrow space.

  It is possible to register the specific gravity of chemicals by clicking the menu button on the audit work screen and selecting master maintenance. That is, the screen is switched to the specific gravity input screen, and the medicine is placed on the balance table 2a.

  For example, when the medicine to be placed is a tablet, the specific gravity, that is, the weight per tablet is automatically calculated and registered by inputting the number of tablets. Similarly, in the case of heat-sealed tablets, the weight per packaging (the minimum unit that can be separated) is calculated and registered by the weight including the blister mount. Further, when the medicine to be placed is an external medicine, for example, if it is a compress, the weight per sheet may be registered as the specific gravity in the same manner as in the case of the tablet. Thereby, even if it is chemical | medical agents other than powder, if it mounts on the balance stand 2a, it will become possible to estimate the quantity correctly.

  Subsequently, the name and dose (target value) of the drug to be weighed are entered in the drug list. The drug name and dose may be entered by displaying a pseudo keyboard on the screen. However, prescription data may be read from the server by inputting the prescription number and automatically displayed on the medicine list.

  In this case, based on the normal dose stored in the medicine master of the storage medium 11 (or server), specifically, the daily dose appropriate range defined by the upper limit value and the lower limit value of the normal dose, the dose is appropriate for the daily dose. Determine whether it is within range. If the dose is within the appropriate daily dose range, the normal dose check process is executed by switching the screen as described later. Also, if the dose is outside the appropriate daily range, an error is displayed to alert the dispenser.

  By the way, only the items that can be input may be input on the audit work screen. Regarding the number of days, minutes, age, and (weight), data of input items is displayed on the button. Thereby, the presence or absence of the data of each item and its value can be easily confirmed. In the following processing, even if there is an item that has not been input, the normal dose check processing is executed based only on the input item, as will be described later.

  When the input on the auditing operation screen is completed, the dispenser selects the medicine bottle containing the medicine to be dispensed based on the contents of the prescription and the barcode reader 7 reads the barcode attached to the medicine bottle. (Step S4), it is determined whether or not the inputted medicine name matches the medicine name read by the barcode reader 7. If they do not match, the medicine to be weighed is incorrect, and as shown in FIG. 12, a warning message is displayed on the screen to notify the dispenser accordingly. In this case, if the error screen is highlighted by making it red, the dispenser can recognize that the medicine has been mistaken at a glance. If they match, the display on the display unit 3 is switched from the audit work screen to the weighing screen shown in FIG. 8 (step S5).

  However, when the setting is performed on the menu of the auditing operation screen and the daily amount setting is selected, the weighing confirmation screen shown in FIG. 10 is once displayed before switching to the weighing screen. The weighing confirmation screen displays drug-related information such as the drug name and normal dose, prescription days, usage, age and weight, as well as the daily dose and the target total amount. However, the target total amount may not be displayed by setting. This helps prevent accidental mistakes by letting the dispenser calculate the target total amount and work his head.

  In the weighing screen, the database is searched for the item “medicine name (1: letter in circle in the drawing)” based on the read barcode, and the corresponding drug name is extracted and displayed. In this case, the display form is changed according to the type classification of the medicine. For example, the display color is black for normal drugs and red for the others. In addition, the category classification is displayed at the top of the medicine name. Further, if the drug has toxicity, a (poison) character is displayed in front of the drug name, and the color of the displayed drug name is displayed in red or the like. As a result, it becomes possible to alert the dispenser when handling the medicine to be dispensed.

  In the item “check method (2: circled characters in the drawing)”, a predetermined display is performed when a check is made while the input state of the weighing condition, that is, the input is insufficient. Here, if it is not entered in any of “days”, “fractions”, “age”, and “weight” indicating the attribute, (reference) is displayed. In addition, when a normal dose is not registered for a patient who is less than 15 years of age, the value calculated by the Augustberger method of (Equation 1) from the adult total amount is used as the normal dose, and (A) is displayed. Furthermore, when the patient is an infant under 1 year old and the normal dose is not registered, the value calculated by the Fried method of (Equation 2) from the adult total amount is used as the normal dose, and (F) is displayed.

  In the item “age (3: circled letters in the drawing)”, the age of the patient is displayed, but when the adult amount data is displayed in the reference display, it is displayed as an adult.

  The item “normal dose unit (4: circled letters in the drawing)” is displayed so that it can be understood in what unit the normal dose is displayed. For example, one day is displayed for internal medicine, one time for non-medication, and one time for external medicine.

  In the item “normal dose display form (5: circled letters in the drawing)”, a symbol indicating what the displayed normal dose is determined based on is displayed. (Total) means the total amount, (Body) means the total amount determined by weight, and (Flat) means the total amount calculated from the average weight of adults.

  In the item “ordinary dose (6: circled letters in the drawing)”, an amount that can be expected to have a therapeutic effect when the medicine is most commonly used is displayed. For the normal dose, the data of the lower limit / upper limit of the age, the ward, the prohibition, the lower limit / upper limit, the lower limit / upper limit of the day, and the upper limit, which are entered for the entered drug name on the normal dose registration screen, are used. In the “age lower / upper limit” column, a lower limit / upper limit that may be taken according to age is entered. In the “Division” column, “kg” indicating the amount per kg of body weight or “total” indicating the amount relative to the total weight is input. In the “prohibited” column, a contraindication category is entered. The “lower limit / upper limit” column is entered once, and the “lower limit / upper limit” column is entered with the lower limit / upper limit for a single day.

  In addition, when any region from the item “check method (2: circled letters in the drawing)” to item “normal dose (6: circled letters in the drawing)” is selected, for example, the common use shown in FIG. Like the dose registration screen, it is possible to display and refer to a list of normal doses corresponding to each item for the selected drug.

  In the item “Notes (7: Circled characters in the drawing)”, the precautions when handling the chemicals described in the remarks column of the chemical master are displayed.

  The item “range (8: circled characters in the drawing)” displays the smallest unit that can be displayed with the number of display digits set by the “RANGE” button. In FIG. 8, it is displayed as 100 mg and is displayed in units of g in the weighing frame, so that one decimal place is displayed.

  In the item “tracking (9: circled characters in the drawing)”, “TRACKING ON” is displayed when tracking is turned on by operating the “stable” button.

  In the item “stability mark (10: circled letter in the drawing)”, “→” is displayed when the weighing state is stabilized. At this time, you may make it alert | report by audio | voice guidance, a buzzer sound, etc.

  In the item “zero display (11: letter in circle in the drawing)”, “0” is displayed if the vicinity of the zero point, that is, the weighing value is approximately 0 kg.

  In the item “Weighing unit (13: circled letters in the drawing)”, a unit suitable for the drug to be weighed is displayed. For example, “g” or “mg” is displayed for powder, and “ml” is displayed for liquid medicine. In the case of a liquid medicine, the result of converting the weighed weight into the capacity based on the registered specific gravity is displayed in the weighing frame. In the case of tablets, that is, when the drug type of the drug master is “tablet (pieces)”, the result of weighing is displayed as the number instead of the weight or volume. In this case, the medicine master measures the weight of a plurality of tablets and divides by the number to store the data as the weight of one tablet. Thereby, an error is suppressed compared with the case where one tablet is measured individually. In registering data in the medicine master, for example, registration buttons such as “Tablet 10”, “Tablet 20”, etc. are displayed, and the designated number of tablets (here, 10 or 20) is placed on the balance table 2a. Just measure. Thereby, the registration to the medicine master is completed as the weight per one tablet.

  When the “stable” button is touched, it is possible to set the stability coefficient, whether there is a configuration based on temperature, and whether to turn on / off tracking. When the “CAL” button is touched, the balance can be calibrated. When the “RANGE” button is touch-operated, it is possible to change the weighing range, that is, the number of digits to be displayed after the decimal point. When the “Tare” button is touched, the zero point setting can be changed depending on whether or not the tray is placed on the balance table 2a. When the “expand” button is touched, the weighing value displayed in the weighing frame can be displayed to a value that is one digit smaller than the predetermined time (here, 10 seconds). When the “Cancel” button is touched, the weighing is stopped. When the “OK” button is touched, the weighing is finished and the weighing value is acquired as the final stable value.

  Note that, as shown in FIG. 22, the weighing screen may be configured to include a filling button and display a target value. When the filling button is clicked, the screen is switched to the filling work screen shown in FIG. This filling work screen has substantially the same configuration as that shown in FIG. 21, and displays columns for dispenser, medicine, medicine bottle, original bottle, lot number, and expiration date. Since it is filling during weighing (replenishment of medicine), the name of the medicine currently being weighed (Akinone fine particles displayed on the weighing screen in FIG. 22) is displayed in the medicine column. The barcode of the medicine bottle containing the medicine to be filled or the original bottle containing the medicine to be filled is read with a barcode reader, and whether or not it matches the medicine name displayed in the medicine column. Judging. If they match, after displaying a match message, the screen returns to the weighing screen of FIG. If they do not match, an error message is displayed, and the system waits for rereading of the barcode. Note that FIG. 23 is a screen displayed during the weighing operation, and it is assumed that there is no chemical in the weighing. Therefore, the columns of the filling amount and the inventory amount as shown in FIG. 21 are not displayed.

  In a state where the weighing screen is displayed, the medicine (contained in the tray) is placed on the balance table 2a according to the prescription amount described in the prescription, and the weighing is started. In this case, the influence of the air flow is eliminated by covering the periphery with a windshield cover as necessary. When the chemicals are sequentially placed on the weighing platform 2a, the weight in weighing is displayed in the weighing frame, and the actual measurement bar corresponding to the weight in weighing is displayed in a different color on the weighing bar. The dispenser can weigh while recognizing how much medicine should be added sensuously based on the change in the length of the actual measurement bar. If the measured value is within the weighing error range (if it reaches the vicinity of the target value line indicating the target value provided in the middle of the weighing bar), the actual bar will change color and allow the dispenser to properly measure the drug. Notify that. In this case, it is preferable to notify by sound.

  If the weighing state is stabilized (step S6), the weighing stability mark “→” is displayed on the left side of the weighing frame (step S7). In addition, the background color of the weighing frame is changed. This display is maintained as long as it is stably weighed. Despite the fact that the weighing value is outside the weighing error range, when the weighing state is stable (or when a predetermined time has passed since the weighing was stabilized, when the enter button is operated, or when the medicine is taken from the weighing scale 2a When the stored tray is removed and a predetermined time has elapsed), the following warning message is displayed. That is, if it is below the weighing error range, a warning message shown in FIG. 13 is displayed, and if it is above the weighing error range, a warning message shown in FIG. 14 is displayed. If the former warning message is displayed, operate the “Yes” button to add chemicals, operate the “No” button to stop weighing, or operate the “Cancel” button to check the weighing screen. Return to and check the displayed contents. If the latter warning message is displayed, the weighing is stopped by operating the “Yes” button, or the weighing is continued by operating the “No” button. This is used when the drug must be weighed above the maximum weight that can be weighed by the drug weighing device. For example, if the maximum value that can be weighed is 15 g, and if it is necessary to weigh 17 g of the drug, first, 15 g which is the maximum amount is weighed to display the warning message in FIG. The remaining 2 g may be weighed.

  After that, when the determination button is operated, or the tray containing the medicine is removed from the weighing platform 2a and a predetermined time has passed (step S8), the value displayed in the weighing frame is set as the final stable value, that is, the weighing value. Ingestion (step S9), the normal dose check process described below is executed (step S10).

  In the normal dose check process, the data related to the normal dose read when the bar code is read and the database (drug data) is searched in step S4 is used.

  Then, as shown in the flowchart of FIG. 4, first, whether or not the data obtained by the input after operating the “days”, “fractions”, “age”, and “weight” buttons is in the medicine master. Judgment is made (step S21). If there is no data, the total adult amount specified by the drug name is displayed as a reference value for the normal dose (step S22). Here, the total amount of adults means the total amount of medicines that can be taken on a daily basis for adults. In this case, the item “check method (2: circled characters in the drawing)” is displayed as (reference), and the normal dose is not checked. That is, only weighing is performed.

  If only the day data, that is, the number of prescription days is input, the weighing value is divided by the number of days (step S23), and the prescription amount per day is calculated. Then, this prescription amount is compared with the daily adult dose (lower limit value to upper limit value) read in step S4 (step S24). If the prescribed amount is not within the range of this normal dose, the screen is switched to an error screen (step S25). In this case, you may make it alert | report with a speaker. This makes it possible to notify that there is a need to take measures such as consulting with a doctor.

  If fraction data, that is, the number of daily doses is input in addition to the day data (step S26), the prescription amount calculated in step S23 is further divided by the fraction to calculate a dose per time (step S27). ). In this case, the weight of the wrapping paper (medicine package) for packaging the drug is taken into consideration. Then, this dose is compared with the normal adult dose (lower limit value to upper limit value) read in step S4 (step S28). As a result, if the dose is not within the range of the normal dose, the error screen is switched as described above (step S25). However, this processing is not performed unless the normal dose for each adult is registered in the drug data.

  If age data has been input, it is compared with the normal dose that falls within the corresponding age range among the data read in step S4 (step S29). In this case, the data to be compared differs depending on whether only the day data is input or whether fraction data is further input. However, when a normal dose according to age is not registered, if it is less than 15 years old, the value obtained by calculation according to the above (Equation 1) is the normal dose, and if it is less than 1 year old, The value obtained by calculating according to) is the normal dose. If the dose is not within the range of the normal dose, the error screen is switched as described above (step S25).

  If the weight data has been input, the data displayed as “kg” in the “ku” column among the data read in step S4 is referred to. Then, the registered normal dose is multiplied by the input body weight to obtain a normal dose according to the body weight (step S30). If a normal dose for each body weight is obtained, it is determined whether or not there is a weighed value within the range of this normal dose (step S31), and if it is not within the range, an error is reported as described above (step S25).

  As a result of performing the normal dose check according to the input weighing conditions in this way, when the measured value is within the range of the normal dose, the “OK” button (15: circled letters in the drawing) is touch-operated. (Step S32), the weighing is stopped and the final stable value is acquired (Step S33). Then, the screen is switched to the audit work screen, and the weighed drug name and the actual measurement value are displayed in the list (step S34). In this case, it is preferable to read out the determined drug name so that the dispenser can confirm it again by hearing.

  When both age data and weight data are input, a normal dose check is performed based on the weight data.

  When a series of weighings is completed as described above, if there is a drug to be weighed next for the same patient, the weighing value is fixed if the attribute clear is set to “none” on the dispensing setting screen. The weighing value and the like are cleared, but the patient data is still displayed on the weighing screen. Thus, the dispenser can continue weighing without the need for patient data input.

<Shaping process>
By the way, in the normal dose check process, when the automatic shaping process is set, the reference amount stored as the shaping data is compared with the value weighed according to the prescribed amount, and the prescribed amount is less than the reference amount. For example, the shaping process is executed.

  Specifically, in the auditing operation screen shown in FIG. 6, when measured values and their total values are displayed for multiple types of drugs, if the value obtained by dividing the total value by the number of days does not meet the reference amount, shaping It becomes the object of processing.

  The automatic shaping process is set by selecting “Yes” in the setting item “whether or not the automatic shaping process is performed at the time of registration”, and is started when the registration button is selected. If “No” is selected, the shaping is not performed, the data is registered as it is, and a message that it is out of the shaping target is displayed.

  In the shaping data, “reference amount” and “fixed shaping amount” can be set according to the difference between “age” and “ward” on the shaping method registration screen shown in FIG. In “Age”, the target age required to be an excipient is entered. “District” defines the shaping method, and “base” means the “reference amount” shaping method and “solid” means the “fixed amount” shaping method, as will be described later. In the “reference amount” shaping method and the “fixed shaping amount” shaping method, different reference values are set for “minute 1” and “minute 2 or more”, that is, whether or not the shaping process is performed. Yes. “Minutes 1” means “1 packet per day”, and “2 minutes or more” means that the daily dose is divided into two or more doses (packaging). For example, in the case of “3 minutes of minutes 2”, there are a total of 6 packages. Therefore, the determination of whether or not the object is to be shaped is compared with the value obtained by dividing the drug weighing value by 6 and the “reference value of minutes 2 or more”. Done. Here, different standard values were set for “minute 1” and “minute 2 or more” because the same standard value was used for “minute 2 or more”. This is to prevent excessive intake of the dosage form.

  In the excipient processing, when multiple types of excipients are set, a list is displayed on the excipient selection screen and selected from the list. If the excipient is specified, the medicine authentication process is performed, and then switching to the shaping screen and weighing is started. When only one type of excipient is set, the selection process is skipped and the process proceeds to the next medicine authentication process.

  In the medicine authentication process, the barcode of the medicine bottle is read by a barcode reader, and the shaping data shown in FIG. 15 is referred to and it is determined whether or not the corresponding excipient is used. If it is not an applicable excipient, “Not the drug” is displayed. If it is a corresponding excipient, the screen is switched to the shaping screen shown in FIG.

  In the case of the “by age” shaping method, a reference value is determined based on the input age, and it is determined whether or not shaping is performed based on the reference value. Also, the reference value is determined depending on whether the “reference amount” shaping method or the “fixed amount” shaping method is used. In the example of FIG. 15, if it is younger than 15 years old, the reference value is determined by the “reference amount” shaping method. The standard value is 1.00 g for “minute 1” and 0.8 g for “minute 2 or more”. If the weight of the prescribed medicine is lower than this value, the shaping process is performed.

  As shown in FIG. 16, on the shaping screen, the name of the excipient is displayed at the top, and the target value of the excipient (here, 2.7 g) is displayed above the weighing frame. Further, a bar-shaped meter portion indicating a reference amount is displayed below the weighing frame. In the meter section, an area indicating the weighing value of the medicine is secured on the right side, and the area of the excipient being weighed is displayed from the left side. Since it is only necessary to add the excipient while observing the display of the meter portion, it is possible to use it as a standard for adding the excipient to the drug, and to improve the workability. In the case of the “fixed amount” shaping method, since the fixed amount is displayed, an excipient may be added so that the fixed amount is obtained. In this case, when the weighing result approaches the target value, it is preferable to notify by a buzzer sound or the like.

  In addition, when the total button is touched on the audit work screen, if the total weighing value is less than the reference amount, the shaping process may be started regardless of whether the automatic shaping process is set. It is possible.

  When a plurality of types of chemicals are mixed and dispensed, they can be weighed sequentially until the “Register” button is operated on the audit work screen. Each time weighing is completed (each time the “OK” button is touched in step S32), the medicine name and the measured amount (weighed value) are added to the list on the auditing work screen and displayed. When mixing powder and liquid medicine, it is preferable to consider the blending changes registered as drug data.

  Further, if the result of the regular dose check is obtained on the audit work screen, the result can be printed by the printer 6 by touching the print button. Note that the number of prints may be changed according to the number of times the print button is touched. Here, it is possible to select three modes of no printing, printing present, and printing 2 (two-sheet printing). It is also possible to automatically determine the presence / absence of data to be printed and not print if there is no data.

  This content is recorded in the storage medium 11 regardless of whether it is actually printed, and it is possible to confirm later what kind of dispensing has been performed by whom.

  Furthermore, when the barcode of the medicine bottle containing this medicine is read again for the medicine weighed once, the addition / reweighing screen (not shown) is displayed and either addition, reweighing or cancellation is performed. Each process can be executed by selecting. In the case of addition, the weighing value is displayed again by adding to the weighing value already registered. In the case of reweighing, clear the weighing value and display the weighing value again. In the case of cancellation, that is, when the barcode of the medicine bottle is read again by mistake, the screen returns to the audit work screen.

<Other embodiments>
In the above embodiment, only the drug data to be handled is extracted from the drug master and stored in the storage medium 11 as the drug to be used. However, when the barcode is read by the barcode reader, the corresponding drug data is stored. In the case of an unadopted drug that has not been used, the normal dose check process may be performed with reference to a drug master stored in a server via a network. In this case, it is preferable to notify that a communication with the server is being performed by flashing a specific portion (for example, drug name) on the weighing screen. Further, in the case of a drug that is not registered in the drug master, it may be temporarily registered as an unregistered drug, and a dispensing inspection, that is, a normal dose check process may be performed.

<Linkage with host system>
Moreover, in the said embodiment, although specific gravity can be registered for every chemical | medical agent in the chemical | medical agent master, it is possible to select which data is used among the data registered on the chemical weighing device side. preferable. For example, modes such as powdered medicine, liquid medicine, external medicine, heat tablet, etc. may be created, and the specific gravity calculation method may be changed according to the selected mode.

  Further, in the above-described embodiment, it has been described that an audit check can be performed by attaching the storage medium 11. However, when the storage medium 11 is not attached, only a drug can be weighed as a normal balance. It has become. That is, the member surrounded by a broken line in FIG. 2 may function as a normal balance, and only this portion may satisfy the measurement method. Then, it is possible to upgrade the version of the audit system simply by correcting the program stored in the storage medium 11. In other words, it is not necessary to test again whether or not the portion that functions as a balance satisfies the measurement method. In the above-described embodiment, a USB memory is connected as the storage medium 11. However, a flash memory (for example, a USB memory) is connected as a storage medium separately from this, and data stored in the storage medium 11 is backed up. It may be. The backup may be automatically performed when starting the chemical weighing device.

  In the above embodiment, only the case where the medicine is stored in the tray placed on the balance table 2a and weighed has been described. However, a read portion such as a barcode or an IC chip may be formed on the tray. . That is, if it is a bar code, it corresponds to the medicine to be accommodated, and if it is an IC chip, information on the medicine to be accommodated is written. For example, when the medicine (powder) contained in the tray is packaged one by one with the powder medicine packaging machine, the medicine information is acquired by reading the read portion provided on the tray, and the powder medicine packaging machine It is preferable to automate the packaging operation.
