Summary of the Invention

Problems to be Solved by the Invention

[0004] The normal dose varies depending on the patient's weight and the like. In this regard, Patent Document 1 describes that a normal dose check is performed even when the patient's weight is not input. Therefore, with the method of Patent Document 1, the accuracy of the normal dose check may be reduced.

[0005] The present invention has been made in view of the above circumstances, and its main object is to provide a drug weighing device capable of determining whether it is possible to perform a highly accurate normal dose check. Means and Effects for Solving the Problems

[0006] The problems to be solved by the present invention are as described above. Next, the means for solving this problem and its effects will be described.

[0007] According to an aspect of the present invention, there is provided a drug weighing device having the following configuration. That is, the drug weighing device includes a weighing unit, a storage unit, and a control unit. The weighing unit weighs drugs. The storage unit stores dispensing data. The control unit performs a usual dose check on the dispensing data stored in the storage unit. Before starting weighing, the control unit determines whether it is possible to perform a usual dose check using the patient's weight based on whether the weight of the patient targeted by the dispensing data is set.

[0008] Since the patient's weight is required for a highly accurate usual dose check, it is possible to determine whether a highly accurate usual dose check can be performed by performing the above processing.

[0009] In the above drug weighing device, when the control unit cannot perform the usual dose check using the patient's weight, it is preferable to prohibit the start of weighing when the patient's age is less than the threshold value and permit the start of weighing when the patient's age is equal to or greater than the threshold value.

[0010] This makes it possible to take particularly strict measures for pediatric patients for whom the importance of the usual dose check is high.

[0011] In the above drug weighing device, when the control unit determines that it cannot perform the usual dose check using the patient's weight, it is preferable to display an input screen for inputting the patient's weight on the display unit.

[0012] This makes it possible to perform a usual dose check by inputting the patient's weight when it can be grasped.

[0013] In the above drug weighing device, it is preferable for the control unit to display the standard weight corresponding to the patient's age on the input screen.

[0014] This makes it possible to present reference information.

[0015] In the above-described drug weighing device, it is preferable to adopt the following configuration. That is, when the control unit cannot perform the usual dose check using the patient's weight, the control unit presents that the usual dose check cannot be executed or that the input of the weight is necessary, and accepts a selection as to whether or not to skip the usual dose check. When it is instructed to skip the usual dose check, weighing is permitted.

[0016] Thereby, it is possible to flexibly cope with various situations as compared with the configuration in which the usual dose check is made essential.

Mode for Carrying Out the Invention

[0018] Next, embodiments of the present invention will be described with reference to the drawings.

[0019] First, the terms used in this specification will be explained.

[0020] The "drug" is a pharmaceutical product for treating or preventing a patient's disease, and is a prescription drug prescribed based on a prescription. The drug is a concept including various dosage forms, and includes, for example, powders, tablets, capsules, aqueous solutions, and ointments.

[0021] "Dispensing" is an operation in which a dispenser weighs a drug and the like based on a prescription to prepare the drug.

[0022] "Prescription data" is data obtained by digitizing the information (prescription information) described in a prescription, and includes, for example, the doctor who issued the prescription, the hospital where the patient was examined, the prescribed drug, the patient's information, the identification information of the prescription, and the like. The prescription data is input into various dispensing devices and used to operate the various dispensing devices. In addition, the data used for dispensing among the prescription data is referred to as dispensing data. Note that the dispensing data is a type of prescription data.

[0023] Drugs may be described in a prescription divided by Rp. "Rp" refers to a prescription recipe, and drugs with the same usage, for example, are described in the same Rp. In addition, the data obtained by digitizing Rp is referred to as Rp data. That is, one piece of prescription data may include one or a plurality of Rp data.

[0024] Next, the outline of the dispensing system 1 will be described with reference to FIG. 1.

[0025] The dispensing system 1 is introduced, for example, into a dispensing pharmacy. The dispensing system 1 is a system for assisting or managing dispensing. The dispensing system 1 includes a medicine weighing device 10, a management device 5, and a packaging machine 20. The medicine weighing device 10, the management device 5, and the packaging machine 20 are connected to a network such as a wired LAN or a wireless LAN, for example, and can communicate with each other.

[0026] The management device 5 is a computer equipped with a CPU, a RAM, a storage, a communication module, etc. The management device 5 performs various processes by the CPU executing a program stored in the storage. The management device 5 manages various information regarding prescriptions, medicines, patients, and dispensing. For example, a dispensing clerk inputs prescription information received from a patient and registers it in the management device 5. Instead of the dispensing clerk inputting it, the management device 5 may receive the prescription information in a data format and register it. The management device 5 creates prescription data based on the prescription information and transmits it to dispensing devices such as the medicine weighing device 10 and the packaging machine 20. Note that the management device 5 may be configured as a part of the medicine weighing device 10 or the packaging machine 20.

[0027] The medicine weighing device 10 has a weighing function and an auditing function. The weighing function is a function of weighing the medicines included in the prescription data. The auditing function is a function of collating (or having the dispenser collate) whether the medicines included in the prescription data are weighed as per the prescription data. Note that the auditing function is not essential and can be omitted. Details of the medicine weighing device 10 will be described later.

[0028] The packaging machine 20 includes a packaging section 21, a processing device 22, and a reading device 23. The packaging section 21 divides the medicines weighed using the medicine weighing device 10 and individually packages them in wrapping paper. The processing device 22 is a microcontroller including a CPU, a RAM, a ROM, a communication module, an I / O port, etc. The processing device 22 performs predetermined processes by executing a program. The reading device 23 is a device capable of reading identification information such as a barcode.

[0029] Next, with reference to FIGS. 1 and 2, the configuration of the drug weighing device 10 will be described in detail.

[0030] The drug weighing device 10 includes a weighing unit 11 for performing weighing. The weighing unit 11 weighs an object (drug) placed on the weighing platform 11a. "Weighing" means measuring the mass value of an object (drug), and the mass value obtained by weighing is the "weighing value". The weighing unit 11 is an electronic balance, which converts the weighing value of an object into a digital signal and outputs it. The weighing unit 11 is, for example, of the tuning fork vibration type, but other types may also be used.

[0031] A weighing container 19 is placed on the weighing platform 11a. The drug to be weighed is put from the drug container into the weighing container 19 and weighed. In addition, a container barcode 19a with the identification information of the weighing container is attached to the weighing container 19. The container barcode 19a is not an essential component and can be omitted. Note that the weighing container 19 is used together with the drug weighing device 10, but the weighing container 19 is not a component of the drug weighing device 10.

[0032] As parts related to information processing, the drug weighing device 10 includes a communication unit 12, a control unit 13, a storage unit 14, and a display unit 15. These are provided in the housing 10a shown in FIG. 2. The communication unit 12 is a communication module and communicates with the management device 5 or the subcontracting machine 20. The control unit 13 is a CPU and performs processing for executing a program. The storage unit 14 is a storage such as a flash memory or an SSD, and stores programs and data necessary for control. The display unit 15 is a display device such as a liquid crystal or an organic EL. The screen generated by the control unit 13 executing a program is displayed on the display unit 15.

[0033] The drug weighing device 10 includes, as devices related to input / output, a touch panel 16, a barcode reader 17, and a form printer 18. The touch panel 16 is disposed on top of the display unit 15 and can detect touch operations by the fingers of the dispenser or a touch pen or the like. The touch panel 16 is a capacitive type, but may be another type such as a pressure-sensitive type. Also, instead of or in addition to the touch panel 16, another type of input device (for example, a hardware key, a mouse, a trackball, etc.) may be provided. The barcode reader 17 reads the container barcode 19a of the weighing container 19, the barcode of the drug container that houses the drugs stored in the dispensing shelf or the like, and the barcode described on the form printed by the form printer 18. In the dispensing system 1, identification information other than the barcode (for example, a two-dimensional code or an RFID tag, etc.) may be acquired. In this case, instead of the barcode reader 17, a two-dimensional code reader or an RFID reader is used. The form printer 18 prints a form indicating information related to weighing at the time of interruption or completion of weighing. The barcode reader 17 and the form printer 18 are not essential components and can be omitted.

[0034] In this embodiment, the weighing unit 11, the display unit 15, the barcode reader 17, and the form printer 18 are separate devices and are connected wirelessly or by wire. This configuration is an example. For example, the weighing unit 11 and the display unit 15 may be integrated. Alternatively, the barcode reader 17 and the form printer 18 may be integrated. Integration means, for example, being disposed within one housing.

[0035] Next, with reference to FIGS. 3 to 7, the weighing function will be described. Also, the auditing function will be briefly described together.

[0036] The flowcharts shown in FIG. 3 and subsequent figures are executed by the control unit 13 of the medicine weighing device 10. Specifically, when the control unit 13 executes a program, the processing of each flow in the flowchart of FIG. 3 is executed. Further, the control unit 13 detects a touch operation performed by the dispenser using the touch panel 16 and performs processing according to the instructions of the dispenser. Hereinafter, the description of the control unit 13 executing the program and the control unit 13 detecting the touch operation of the dispenser may be omitted.

[0037] First, the control unit 13 creates an audit list screen and outputs it to the display unit 15, thereby causing the display unit 15 to display the audit list screen (weighing list screen) (S101), and waits for the dispenser to select prescription data. The display conditions of the audit list screen are various. For example, the audit list screen may be automatically displayed when the medicine weighing device 10 is started up. Alternatively, the audit list screen may be displayed when the dispenser gives an instruction to display the audit list screen.

[0038] Hereinafter, with reference to FIG. 4, the audit list screen will be described. The "audit list screen" is a screen showing a list of prescription data to be audited. Since the prescription data to be audited is also candidate prescription data to be weighed, the audit list screen may be paraphrased as the weighing list screen. On the audit list screen 30, an un-audited tab 31, an interrupted tab 32, an audited tab 33, a deletion tab 34, and a list display area 30a are displayed.

[0039] When the dispenser selects the un-audited tab 31, a list of prescription data in an incomplete state is displayed in the list display area 30a. The "incomplete state" is a state in which the weighing of all the medicines included in the prescription data has not started. Therefore, the prescription data immediately after being received from the management device 5 is in an incomplete state. Further, since the audit is executed along with the weighing, the incomplete state can also be paraphrased as an "un-audited state" in which the audit of all the medicines has not started. The control unit 13 displays a bracketed number next to "un-audited" of the un-audited tab 31. This number indicates the number of pieces of prescription data in an incomplete state. By looking at the number of incomplete pieces, the dispenser can easily grasp the remaining status of the dispensing.

[0040] In the list display area 30a, various information included in the prescription data is shown item by item using icons or character strings or the like. Specifically, in the incomplete prescription data of FIG. 4, in order from the left, the dosage form icon, priority, reception date and time, reception number, patient ID, and prescription classification items are displayed. Although not shown, items such as medical institution (or ward), department of medicine, start date of use, total number of dispensings, and total number of drugs are further displayed. The dosage form icon is an icon indicating the dosage form of the drug included in the prescription data. The dosage form icon corresponds to the "type information" indicating the type of the drug. Note that instead of the dosage form icon, the type of the drug may be indicated by characters. The priority is information that divides the priority of dispensing into a plurality. For example, the priority may be increased according to the elapsed time from the time when the prescription was received. Also, the dispenser or the pharmacist may be able to manually set the priority. The reception date and time is the date and time when the drug weighing device 10 received the prescription data from the management device 5. Note that the reception date and time may be the date and time when the management device 5 received the prescription information. The patient ID is identification information of the patient for identifying the patient. The prescription classification is information indicating classifications such as regular prescription and temporary prescription. Also, by the dispenser sliding the slide bar left and right or the like, the control unit 13 causes another item to be displayed in the list display area 30a. The above-described items are examples, and other items may be displayed. Also, for the incomplete prescription data, the items to be displayed in the list display area 30a can be set in advance.

[0041] The prescription data that the control unit 13 causes to be displayed in the list display area 30a is sorted by a predetermined item. In the present embodiment, the priority is set as the default (initial state) item used for sorting the incomplete prescription data. Therefore, as shown in the list display area 30a where the incomplete prescription data of FIG. 4 is displayed, the control unit 13 sorts and displays the prescription data so that the higher the priority, the higher the prescription data is displayed in the upper side of the list display area 30a. Note that the item used for sorting can be changed. For example, by selecting the reception date and time, the control unit 13 sorts and displays the prescription data so that the older the reception date and time, the higher the prescription data is displayed in the upper side of the list display area 30a.

[0042] The control unit 13 can also extract prescription data that satisfies predetermined conditions and display it in the list display area 30a. For example, on the audit list screen 30, a dosage form selection button 35 is displayed. The dosage form selection button 35 includes buttons indicating a plurality of types of dosage forms. The control unit 13 extracts the prescription data of the dosage form corresponding to the selected button and displays it in the list display area 30a. In addition, the control unit 13 can also display the prescription data extracted using items other than the dosage form (for example, priority) in the list display area 30a.

[0043] Each time the control unit 13 receives new prescription data from the management device 5, it updates the list display area 30a in the incomplete state and adds and displays the new prescription data. However, when the dispenser is scrolling the list display area 30a up and down, updating the list display area 30a will interfere with the dispenser's work. Therefore, the control unit 13 does not update the list display area 30a while the dispenser is scrolling the list display area 30a up and down. After the dispenser finishes scrolling the list display area 30a up and down and a predetermined time has elapsed, the control unit 13 updates the list display area 30a and displays the new prescription data.

[0044] When the dispenser selects the interruption tab 32, a list of prescription data in the interrupted state is displayed in the list display area 30a. The "interrupted state" means that the weighing of only some of the drugs included in the prescription data is completed and the weighing of other drugs is interrupted. Even when a list of prescription data in the interrupted state is displayed in the list display area 30a, a plurality of items are displayed in the same way as when a list of prescription data in the un-audited state is displayed. In addition, the control unit 13 displays a numbered item in parentheses next to "Interruption" on the interruption tab 32. This number indicates the number of pieces of prescription data in the interrupted state.

[0045] When the dispenser selects the audited tab 33, a list of prescription data in the completed state is displayed in the list display area 30a. The "completed state" means a state in which the weighing of all the drugs included in the prescription data has been completed. When the dispenser selects the deletion tab 34, a list of prescription data in the deleted state is displayed in the list display area 30a. Since the prescription data in the completed state and the deleted state have low importance, the number of each case is not displayed (it may be displayed). Also, the audited tab 33 or the deletion tab 34 may be omitted.

[0046] In S102 to S105, the control unit 13 performs processing related to the selection of prescription data to be weighed. After the control unit 13 causes the audit list screen 30 to be displayed on the display unit 15, it determines whether prescription data has been selected (S102). Specifically, in the audit list screen 30, when the dispenser performs an operation of selecting prescription data in the incomplete state or the interrupted state as the weighing target, the control unit 13 determines that the prescription data has been selected. Then, the control unit 13 causes the prescription content screen of the selected prescription data to be weighed to be displayed on the display unit 15 (S103), and waits for an instruction for weighing preparation from the dispenser.

[0047] Hereinafter, with reference to FIG. 5, the prescription content screen will be described. The "prescription content screen" is a screen for collectively displaying the content of prescription data on one screen. In the above-described audit list screen, the outline of each prescription data is displayed, and the details of the prescription data such as the information of the Rp data and the drug information included in the prescription data are not displayed. Also, in the weighing preparation screen described later, only the information of one Rp data is displayed, and the displayed Rp data can be switched. In contrast, in the prescription content screen, the information of all Rp data (in particular, the drug name, usage method, and total amount included in the Rp data) is displayed simultaneously. The dispenser looks at the prescription content screen and determines whether to weigh the prescription data. As shown in FIG. 5, the prescription content screen 40 displays a prescription information area 41, an Rp list information area 42, a confirmation item area 43, and a weighing preparation button 44.

[0048] In the prescription information area 41, basic information regarding the prescription data, in other words, information other than the medicine, is displayed. In the prescription information area 41, for example, the reception number, hospital name, dispenser, patient name, information regarding the patient, etc. are displayed. Also, when the patient corresponds to a pediatric patient or an elderly patient, an icon indicating that the patient is a pediatric patient or an elderly patient is displayed beside the patient name. Also, the color of this icon may be made different according to the gender of the patient.

[0049] In the Rp list information area 42, information on all Rp data of the selected prescription data is displayed. If the number of Rp data is large and does not fit in the Rp list information area 42, by scrolling, information on all Rp data is displayed. In the Rp list information area 42, for each Rp data, an audit status column, a medicine name and usage method column, and a total amount column are displayed. In the audit status column, it is displayed whether weighing and auditing have been completed. When the Rp data has not been weighed and audited, an icon indicating that fact (specifically, a circle without a check mark) and the text "not audited" are displayed. Also, the prescription data in the interrupted state may include Rp data for which weighing and auditing have been completed. When the Rp data has been weighed and audited, an icon indicating that fact (specifically, a circle with a check mark) and the text "audited" are displayed.

[0050] In the confirmation item area 43, a list of the check results of the dispensing contents of the prescription data is displayed. By looking at the confirmation item area 43, the dispenser can immediately grasp that there are no items with NG checks. When the dispenser weighs the prescription data displayed on the prescription content screen 40, the weighing preparation button 44 is operated.

[0051] Note that the display of the prescription content screen 40 is not essential, and the control unit 13 may omit the display of the prescription content screen 40 and cause the weighing preparation screen 50 described later to be displayed on the display unit 15. Also, the confirmation item area 43 in the prescription content screen 40 may be omitted.

[0052] After the control unit 13 causes the prescription details screen 40 to be displayed on the display unit 15, it determines whether there is an instruction for weighing preparation (S104). When the control unit 13 detects that the dispenser has operated the weighing preparation button 44, it determines that there is an instruction for weighing preparation. Then, the control unit 13 causes the weighing preparation screen to be displayed on the display unit 15 (S105). When the control unit 13 displays the prescription data to be weighed on the weighing preparation screen, it ends the process related to the selection of the prescription data to be weighed.

[0053] Hereinafter, with reference to FIG. 6, the weighing preparation screen will be described. The weighing preparation screen is a screen for displaying prescription data and information related to weighing. As shown in FIG. 6, on the weighing preparation screen 50, a prescription information area 51, a weighing mode display area 52, an Rp tab 53, an Rp information area 54, a drug information area 55, a confirmation item button 56, and a menu button 57 are displayed.

[0054] In the prescription information area 51, the same information as the prescription information area 41 of the above-described prescription details screen 40 is displayed. Further, the drug weighing device 10 can set a weighing mode according to the type (form) of the drug. The drug weighing device 10 can set, for example, a weighing mode according to powder, aqueous solution, external preparation (ointment). In the weighing mode display area 52, the currently set weighing mode is displayed.

[0055] The Rp tab 53 is displayed for each Rp data included in the prescription data. The Rp tab 53 is a selection button for selecting the Rp data to be weighed. Each time the Rp tab 53 is operated, the Rp data to be weighed is switched, and the Rp data to be weighed is displayed in the Rp information area 54 and the drug information area 55 described later. On the Rp tab 53, a display item (the characters "not yet" or "completed") indicating whether the dispensing of the corresponding Rp data has been completed is displayed. Thereby, it is possible to easily grasp whether the weighing of another Rp data has been completed while a certain Rp data is being displayed.

[0056] In the Rp information area 54 and the drug information area 55, information regarding weighing according to the Rp data is displayed. In the Rp information area 54, information regarding Rp data in general, such as usage method, the ID of the weighing container 19 used for weighing, and the start date of use, is displayed. In the drug information area 55, information for each drug included in the Rp data, such as for each drug, drug classification, drug name, daily dose (dose per day), total dose (total dose of the Rp data), weighing value, authentication skip icon, etc., is displayed. In the drug classification, an icon indicating whether the drug belongs to a specific type (e.g., a highly toxic drug or a narcotic drug, etc.) is displayed. The authentication skip icon is an icon for skipping the authentication as to whether the drug in the Rp data matches the drug picked up by the dispenser from the dispensing shelf or the like. Each piece of information in the Rp information area 54 and the drug information area 55 is an example and can be changed as appropriate.

[0057] Also, by selecting the Rp data and the dispenser using the barcode reader 17 to read the container barcode 19a of the weighing container 19, the identification information (container ID) of the weighing container 19 used for weighing the drug included in the selected Rp data can be registered (stored) in association with the Rp data. Note that this process is not necessarily required and can be omitted by operating the "Skip" shown in FIG. 6.

[0058] The confirmation item button 56 is a button for displaying the check result of the prescription data (contents displayed in the confirmation item area 43). The menu button 57 is a button for displaying the setting items regarding weighing.

[0059] In S106 - S107, the control unit 13 performs processing related to the selection of the drug to be weighed. After causing the weighing preparation screen 50 to be displayed on the display unit 15, the control unit 13 selects the Rp data of the drug to be weighed according to the operation of the dispenser. Then, the control unit 13 determines whether the barcode of the drug included in the Rp data of the drug to be weighed has been read by the barcode reader 17 (S106). Here, a drug database is stored in the storage unit 14 of the drug weighing device 10. The drug database is a database that associates drug information (drug name, drug details (e.g., dosage form)) with the barcode (identification information) attached to a drug bottle or the like. Note that the drug database may be stored in the management device 5. The control unit 13 can determine whether the barcode of the drug included in the Rp data of the drug to be weighed matches the read barcode by accessing the drug database. When the control unit 13 determines that the barcode of the drug included in the Rp data of the drug to be weighed has been read, it causes the weighing screen 60 for the drug to be displayed on the display unit 15 (S107). When the control unit 13 selects the drug included in the Rp data of the drug to be weighed that matches the read barcode as the drug to be weighed and causes the weighing screen 60 for the selected drug to be weighed to be displayed on the display unit 15, the processing related to the selection of the drug to be weighed ends. Note that when the drug to be weighed is selected by the touch operation of the dispenser, the control unit 13 also causes the weighing screen 60 to be displayed on the display unit 15.

[0060] Hereinafter, with reference to FIG. 7, the weighing screen will be described. The weighing screen is a screen that is displayed while the drug is being weighed. As shown in FIG. 7, on the weighing screen 60, a drug information area 61, a weighing bar area 62, a weighing value area 63, a determination area 64, and an OK button 65 are displayed.

[0061] In the drug information area 61, prescription data, Rp data, or basic information about the drug to be weighed is displayed. The weighing bar area 62 is a part that graphically displays the weighing value. In the weighing bar area 62, the target lower limit value, the weighing target value, and the target upper limit value are displayed as a percentage (%) and a numerical value (g). Also, as the weighing value increases, the bar becomes longer. The dispenser may perform weighing so that the bar exceeds the target lower limit value and does not exceed the target upper limit value. Thereby, the dispenser can intuitively grasp the relationship between the current weighing value and the target value. In the weighing value area 63, the current weighing value is displayed numerically. In the determination area 64, the determination result of the weighing value is shown. When the weighing value exceeds the target lower limit value and does not exceed the target upper limit value, "OK" is displayed in the determination area 64, and otherwise, "NG" is displayed in the determination area 64. Thereby, it is possible to collate (or let the dispenser collate) whether the drug included in the prescription data is weighed as per the prescription data. The display mode of the current weighing value and the target value is an example, and any of the above-described display elements may be omitted or displayed in other modes.

[0062] The confirmation button 65 is a button that the dispenser operates when completing the weighing of the drug. When the control unit 13 determines that the confirmation button 65 has been operated and the weighing is completed (S108), the control unit 13 stores the weighing value at the time when the weighing is confirmed in the storage unit 14 in association with the prescription data, Rp data, and the drug (S109). Note that instead of operating the confirmation button 65, when "OK" is displayed in the determination area 64 and the weighing value has stabilized (the change amount per predetermined time has become substantially zero), the control unit 13 may determine that the weighing is confirmed. Note that by operating the buttons displayed on the weighing screen 60, it is also possible to cancel or skip the weighing of the current drug.

[0063] The control unit 13 repeats the above processing until the weighing of all the drugs in the prescription data of the object to be weighed is completed. After the weighing of one drug is completed, if the control unit 13 determines that the weighing of all the drugs has not been completed (S110), it displays the weighing preparation screen 50 again (S105). And when the control unit 13 determines that the barcode of the unweighed drug included in the Rp data has been read, it causes the weighing screen 60 for the drug to be displayed on the display unit 15. Note that when the weighing of all the drugs included in one Rp data is completed, the next Rp data may be displayed on the weighing preparation screen 50.

[0064] When the control unit 13 determines that the weighing of all the drugs in the Rp data of the object to be weighed is completed (S110), it causes the audit list screen to be displayed on the display unit 15 (S101) and waits for the dispenser to select the next prescription data. As described above, the weighing and auditing of the drugs included in the prescription data can be performed using the drug weighing device 10.

[0065] Next, with reference to FIGS. 8 to 12, the processing related to the check of the prescription data will be described.

[0066] In the following description, when referred to as "check of prescription data", it indicates the check of the dispensing content of the prescription data. By checking the prescription data, it is detected that the prescription data itself is inappropriate. When the control unit 13 determines that it has received the prescription data from the management device 5 (S201 in FIG. 8), it stores the prescription data in the storage unit 14 (S202).

[0067] Next, the control unit 13 performs a check of the prescription data (S203). The control unit 13 starts the check of the prescription data triggered by receiving the prescription data from the management device 5. In other words, when the control unit 13 receives the prescription data from the management device 5, it starts the check of the prescription data without waiting for the dispenser's instruction. Note that the control unit 13 may perform another process before starting the check of the prescription data after receiving the prescription data from the management device 5. Another process is, for example, a dispensing design that determines the specific dispensing content based on the prescription data.

[0068] The control unit 13 performs a plurality of prescription data check items, specifically including normal dose check, long-term administration check, incompatibility check, discontinued drug check, and same drug check. Note that at least one of these check items may be omitted, or another check may be performed. Hereinafter, the contents of these check items will be specifically described.

[0069] The normal dose check is to check whether the dose of the drug included in the prescription data is within the range of the normal dose. The normal dose is the range of drug doses commonly used in anticipation of the effect of the drug on the disease. Also, the normal dose may vary depending on the patient's age, gender, weight, body surface area, etc. In the above-described drug database, the normal dose is registered for each drug. The control unit 13 performs a normal dose check by comparing the dose of the drug included in the prescription data with the normal dose registered in the drug database. If the dose of the drug included in the prescription data is within the range of the normal dose, the check result is "OK", and if it exceeds the normal dose, the check result is "NG".

[0070] The long-term administration check is to check whether the administration period of the drug included in the prescription data is below the upper limit value. An upper limit value is defined for the administration period, and the upper limit value may vary depending on the drug. For example, for new drugs, the upper limit value of the administration period may be shorter. The upper limit value of the administration period is registered in the drug database. The control unit 13 performs a long-term administration check by comparing the period indicated by the usage method of the drug included in the prescription data with the upper limit value of the administration period registered in the drug database. If the period indicated by the usage method of the drug included in the prescription data is below the upper limit value of the administration period, the check result is "OK", and if it exceeds the upper limit value of the administration period, the check result is "NG".

[0071] The compatibility check is to check whether the combination of drugs subject to compatibility taboos is included in the prescription data. Compatibility taboo means that when two types of drugs are combined, the drug efficacy may decrease or coloring may occur, etc., so the combination is not allowed. Note that drugs that are incompatible with each other are not allowed to be sub-packaged in the same packaging material, but are allowed to be sub-packaged in different packaging materials. The combinations of drugs that are incompatible with each other are registered in the drug database. The control unit 13 performs a compatibility check by comparing the combination of drugs included in the prescription data with the combination of drugs that are incompatible with each other registered in the drug database. When the combination of drugs included in the prescription data is not a compatibility taboo, the check result is "OK", and when the combination of drugs included in the prescription data is a compatibility taboo, the check result is "NG".

[0072] The discontinued drug check is to check whether the discontinued drug, which is a drug determined not to be used in the dispensing pharmacy, is included in the prescription data. The discontinued drugs are registered in the drug database. The control unit 13 performs a discontinued drug check by comparing the names of the drugs included in the prescription data with the names of the discontinued drugs registered in the drug database. When the drug included in the prescription data is not a discontinued drug, the check result is "OK", and when the drug included in the prescription data is a discontinued drug, the check result is "NG".

[0073] The same drug check is to check whether there are multiple identical drugs in one prescription data. Usually, there is only one identical drug in one prescription data, so if there are multiple identical drugs, there may be an error in the prescription. The control unit 13 performs the same drug check by analyzing the prescription data. When there is one identical drug in the prescription data, the check result is "OK", and when there are multiple identical drugs in the prescription data, the check result is "NG".

[0074] In the above description, it was explained that "OK" or "NG" is displayed for each check item. However, when the information necessary for checking the prescription data is not complete or not registered, the control unit 13 may display that it was unable to perform the check of the prescription data, such as "――".

[0075] The control unit 13 performs the above check of the prescription data and stores the check result of the prescription data in the storage unit 14 for each check item (S204). The above process is performed every time prescription data is received from the management device 5.

[0076] Next, the display of the check result of the prescription data will be described. FIG. 9 is a flowchart extracting the process related to the display of the check result among the processes performed by the control unit 13. When the control unit 13 determines that there is prescription data with a check result of "NG" (S301) and it is the display timing of the audit list screen 30 (S302), as shown in FIG. 10, it adds "Yes" to the confirmation item of the prescription data with a check result of "NG" and displays the audit list screen 30 (S303).

[0077] As shown in FIG. 10, the items that can be displayed in the list display area 30a include confirmation items. "Yes" or "No" is displayed for the confirmation items. When at least one "NG" is included in the check result of the prescription data, the control unit 13 causes "Yes" to be displayed for the confirmation item. When the check result of the prescription data is all "OK", the control unit 13 causes "No" to be displayed for the confirmation item. By not showing the detailed check result on the audit list screen 30, it is possible to suppress the information displayed in the list display area 30a from becoming excessive and improve the listability. Also, in order to make it conspicuous that the check result is "NG", the display modes of "Yes" and "No" may be made different. The display mode is the way of displaying the display object, for example, color, presence or absence of blinking, presence or absence of additional marks, etc.

[0078] If the prescription data is checked after the weighing of the drug has started, and the check result of the prescription data is "NG", it may be necessary to discard the drug and reweigh the drug. Also, when the prescription data is checked at the timing when the prescription data to be weighed is selected, if the process of returning to the list of prescription data (audit list screen 30) without starting the weighing is performed, the processing load on the control unit 13 tends to increase. In addition, the time from when the prescription data to be weighed is selected until the prescription content screen 40 (particularly the confirmation item area 43) is displayed may become longer.

[0079] In this regard, in the present embodiment, the prescription data is checked in advance and the check result is stored. Thereby, a situation where it is necessary to discard the drug and reweigh the drug does not occur. Also, when the prescription data to be weighed is selected, the check result can be displayed in the confirmation item area 43 simply by reading out the stored check result. Therefore, the time until the confirmation item area 43 is displayed can be shortened while suppressing the processing load on the control unit 13.

[0080] Also, in the present embodiment, the check result of the prescription data is displayed on the audit list screen 30 using the confirmation items in the list display area 30a. Instead of this, for example, the color of the row of the prescription data including "NG" in the check result may be changed, or a mark such as "Check NG" may be added to the row of the prescription data including "NG" in the check result. Also, when adding a mark, different marks may be added according to the check items that became "NG". That is, as long as the correspondence between the prescription data and the check result of the prescription data is shown, the display method can be changed as appropriate.

[0081] In addition, it is assumed that the confirmation item in the list display area 30a is usually "none". Therefore, when the confirmation item of all the prescription data displayed on the audit list screen 30 is "none", the control unit 13 does not include the confirmation item in the items initially displayed in the list display area 30a, and only when the confirmation item of at least one prescription data displayed on the audit list screen 30 includes "yes", the confirmation item may be included in the items initially displayed in the list display area 30a.

[0082] Next, when the control unit 13 determines that the prescription data including "NG" in the check result is selected as the weighing target (S304), as shown in FIG. 11, the control unit 13 causes the display unit 15 to display the prescription content screen 40 with the check result for each check item and the reason for "NG" (S305).

[0083] As described above, the prescription content screen 40 includes the confirmation item area 43. In the confirmation item area 43, the check result for each check item is shown. Further, when the check result is "NG", the reason for the check result being "NG" is displayed in the confirmation item area 43. Also on the prescription content screen 40, similar to the audit list screen 30, a display mode that makes it prominent that the check result is "NG" may be adopted.

[0084] By displaying the reason for the check result of "NG" for each check item on the prescription content screen 40, the dispenser can determine whether to weigh the corresponding prescription data in consideration of the detailed content of the check result.

[0085] Next, after the control unit 13 causes the display unit 15 to display the weighing preparation screen 50 according to the operation of the dispenser as described above, the control unit 13 determines whether the confirmation item button 56 is operated on the weighing preparation screen 50 (S306). When the control unit 13 determines that the confirmation item button 56 is operated, as shown in FIG. 12, the control unit 13 causes the display unit 15 to display the confirmation item screen 58 (S307).

[0086] As shown in FIG. 12, on the confirmation item screen 58, a confirmation item area 58a, a detailed information display area 58b, and a return button 58c are displayed. In the confirmation item area 58a, the same information as the confirmation item area 43 of the prescription content screen 40 is displayed. In the detailed information display area 58b, more detailed information regarding the check result is displayed. For example, in the detailed information display area 58b, an extract of the drug database used in the check of the prescription data and the like is displayed. Although information regarding the compatibility check is displayed in the detailed information display area 58b shown in FIG. 12, detailed information regarding other check items may also be displayed. Further, when the control unit 13 determines that the button 58c has been operated, the weighing preparation screen 50 is again displayed on the display unit 15.

[0087] By providing the confirmation item button 56 on the weighing preparation screen 50, the dispenser can check the check result of the prescription data without returning to the prescription content screen 40. Further, the dispenser can also check more detailed information regarding the check result of the prescription data. Further, instead of changing the screen from the weighing preparation screen 50 to the confirmation item screen 58, the confirmation item screen 58 may be pop-up displayed on the weighing preparation screen 50. Note that displaying the confirmation item button 56 and the confirmation item screen 58 is not an essential element and can be omitted.

[0088] Further, the checks of the prescription data differ in nature for each check item. Therefore, when the check result of the prescription data is "NG", the control unit 13 of the present embodiment performs processing according to the check item. This will be specifically described below.

[0089] When the check result of the usual dose check is "NG", the dose of the drug included in the prescription data is smaller or larger than the usual dose. Here, since the usual dose is the dose of the drug that is commonly used, a dose smaller or larger than the usual dose may be intentionally prescribed under special circumstances. Therefore, when the check result of the usual check is "NG", the control unit 13 displays a warning to the effect that the check result is "NG" on the prescription content screen 40 or the like, but does not prohibit weighing.

[0090] If the check result of the long-term administration check is "NG", the dosing period of the drug contained in the prescription data exceeds the upper limit value. Exceeding the upper limit value of the dosing period is not allowed. Therefore, when the check result of the long-term administration check is "NG", the control unit 13 displays a warning indicating that the check result is "NG" on the prescription content screen 40 or the like, and prohibits weighing. The process of prohibiting weighing is, for example, to gray out the weighing preparation button 44 and make it inoperable. Further, the control unit 13 may display either or both of the reason why the check result is "NG" and the fact that weighing is prohibited in the confirmation item area 43.

[0091] If the check result of the incompatibility check is "NG", the drugs contained in the prescription data are incompatible with each other. As described above, it is not allowed to sub-package incompatible drugs in the same packaging material, but it is allowed to sub-package them in different packaging materials. Therefore, the control unit 13 adds new Rp data and moves one of the incompatible drugs to the new Rp data. Then, by performing sub-packaging in units of Rp data in the sub-packaging machine 20, the incompatible drugs can be sub-packaged in different packaging materials. Further, the control unit 13 may display an explanation such as dividing the Rp data by operating the weighing preparation button to eliminate the "NG" in the confirmation item area 43. Alternatively, the control unit 13 may display that the Rp data has been divided and the "NG" has been eliminated when the prescription content screen 40 is displayed or when the weighing preparation screen 50 is displayed.

[0092] If the check result of the discontinued drug check is "NG", the prescription data contains a discontinued drug. The use of a discontinued drug is not allowed. Therefore, when the check result of the discontinued drug check is "NG", the control unit 13 displays a warning indicating that the check result is "NG" on the prescription content screen 40 or the like, and prohibits weighing. Further, the control unit 13 may display either or both of the reason why the check result is "NG" and the fact that weighing is prohibited in the confirmation item area 43.

[0093] When the check result of the same drug check is "NG", the prescription data contains multiple occurrences of the same drug. Here, depending on the usage method of the drug, the prescription data may also contain multiple occurrences of the same drug. Therefore, when the check result of the same drug check is "NG", the control unit 13 displays a warning indicating that the check result is "NG" on the prescription content screen 40 or the like, but does not prohibit weighing.

[0094] To summarize the above, for check items where weighing is permitted even if the check result is "NG", the control unit 13 displays a warning and does not prohibit weighing. Also, for check items where weighing is prohibited when the check result is "NG" but countermeasures are possible, the control unit 13 takes countermeasures and does not prohibit weighing. Further, for check items where weighing is prohibited and no countermeasures are possible when the check result is "NG", the control unit 13 prohibits weighing. Additionally, when the check result is "NG" and weighing is not prohibited, the control unit 13 may display both or either the reason why the check result is "NG" and the fact that weighing is not prohibited in the confirmation item area 43.

[0095] As described above, the drug weighing device 10 of this embodiment performs the process of displaying the check result of the prescription data.

[0096] Next, with reference to FIGS. 13 to 15, the process related to weight input for the usual dose check will be described.

[0097] As described above, the usual dosage used in the usual dosage check may vary depending on the patient's age, gender, weight, body surface area, etc. Among these factors, weight is a particularly important factor in relation to the usual dosage. For example, based on the information obtained by a doctor from a patient in a hospital, the patient's weight may be included in the prescription data. In addition, the management device 5 stores a patient database, which is data of patients who have used a dispensing pharmacy in the past. In the patient database, in addition to the name, date of birth, and history of prescribed drugs, the weight may be registered. However, if the patient's weight cannot be identified from the prescription data and the patient database, an appropriate usual dosage check may not be possible. Even if the patient's weight is registered in the patient database, it may be significantly different from the current patient's weight. Especially in pediatric patients, since the weight increases significantly over time, the difference between the weight in the patient database and the current weight is likely to be large.

[0098] In consideration of the above circumstances, in order to appropriately perform the usual dosage check for a patient (especially a pediatric patient), the drug weighing device 10 of the present embodiment performs a process (the process shown in the flowchart of FIG. 13) for inputting the patient's weight during the process of selecting the prescription data to be weighed.

[0099] First, when the control unit 13 determines that the weighing preparation button 44 has been operated on the prescription content screen 40 (S601), it determines whether the weight is included in the prescription data (S602). In other words, the control unit 13 determines whether the weight of the patient targeted by the prescription data is set.

[0100] The weight included in the prescription data is considered to accurately indicate the patient's current weight. Therefore, when the control unit 13 determines that the prescription data includes the weight, in the prescription data check (S201 to S204) performed when receiving the prescription data from the management device 5, it is determined that the usual dose check based on the patient's current weight has been performed, and no special processing is performed thereafter. Note that the weight registered in the patient database may have a large difference from the patient's current weight. Therefore, the control unit 13 performs the processing after S603 regardless of whether the weight is registered in the patient database. Instead of this, when the patient's weight is registered in the patient database (that is, when the patient's weight in the prescription data is set), the processing after S603 may be omitted.

[0101] When the control unit 13 determines that the weight is not included in the prescription data, it determines whether the patient is a pediatric patient (S603). A pediatric patient is a patient under 15 years old. Therefore, in other words, the control unit 13 determines whether the patient's age is less than the threshold value. In adult patients, the weight change over time is small, so in this embodiment, it is not the target of the weight input process. However, as will be described later, the weight input process can also be performed in adult patients.

[0102] When the patient is a pediatric patient, the control unit 13 temporarily stops the display process of the weighing preparation screen 50 and causes the weight input screen 100 shown in FIG. 14 to be displayed on the display unit 15 (S604). Here, temporarily stopping the display process of the weighing preparation screen 50 is, in other words, a process of prohibiting the start of drug weighing. Further, the control unit 13 may perform a screen transition from the prescription content screen 40 to the weight input screen 100, or may pop up and display the weight input screen 100 on the prescription content screen 40.

[0103] As shown in FIG. 14, on the weight input screen 100, a notification area 101, a registered weight area 102, a standard weight area 103, and a weight input box 104 are displayed. Further, on the weight input screen 100, a weighing button 105 and a check skip button 106 are displayed.

[0104] In the notification area 101, the reason for displaying the weight input screen 100 and the request for weight input are displayed. Specifically, in the notification area 101, "Prescriptions for pediatric patients are audited. Please enter your weight." is displayed. In the registered weight area 102, information on the patient of the prescription data for weighing, particularly information regarding the registered weight, is displayed. Specifically, in the registered weight area 102, the patient's name, registered weight, and registration date are displayed. In the standard weight area 103, the standard weight corresponding to the patient's age and gender is displayed.

[0105] The weight input box 104 is a box for the dispenser to enter the patient's weight. The dispenser can enter the patient's weight by selecting the weight input box 104 and entering a numerical value. In this embodiment, when the weight input screen 100 is displayed, the weight input box 104 is blank and no numerical value is described. Thus, it is necessary for the dispenser to operate the weight input box 104 by hand to enter the patient's weight. Therefore, a step of entering the weight heard from the patient by the dispenser is required, so the accuracy of the usual dose check is increased. From the perspective of work efficiency, the weight of the most recently registered patient or the standard weight corresponding to the patient's age and gender may be described as the default numerical value in the weight input box 104. In this case, the dispenser can start the usual dose check and weighing only by confirming the weight and operating the weighing button 105 described later.

[0106] When the weight is input into the weight input box 104, the control unit 13 stores the input weight in the storage unit 14 and transmits it to the management device 5 in association with the patient information (S605). The management device 5 updates the patient database using the received patient information and weight. Thereby, in the subsequent processing, information such as the registered weight can be displayed in the registered weight area 102.

[0107] Next, the control unit 13 performs a normal dose check based on the input body weight and the above-described drug database, and causes the weighing preparation screen 50 to be displayed on the display unit 15 (S606). The dispenser can confirm the check result of the normal dose check, for example, by operating the confirmation item button 56 on the weighing preparation screen 50. Alternatively, the control unit 13 may pop up and display the check result of the normal dose check on the display unit 15 before displaying the weighing preparation screen 50. Further, the control unit 13 may pop up and display the check result only when the check result is "NG". Thereby, since the normal dose check is performed based on the body weight included in the prescription data or the body weight confirmed and input by the dispenser, an appropriate check result can be obtained.

[0108] Also, when the control unit 13 determines that the check skip button 106 has been operated, the prohibition of weighing is released, and the weighing preparation screen 50 is displayed without performing the normal dose check. Thereby, the dispenser can start weighing. Note that the display of the body weight input screen 100 is an example, and for example, the registered body weight area 102, the standard body weight area 103, and the check skip button 106 may be omitted.

[0109] In this embodiment, the control unit 13 can input the patient's weight during the process (S102 to 105) related to the selection of prescription data for the weighing target. In other words, it can input the patient's weight between receiving the selection of prescription data for the weighing target in S102 and displaying the weighing preparation screen related to the prescription data for the weighing target on the display unit 15 in S105. That is, the patient's weight can be input while the prescription data for the weighing target is selected. Therefore, it is not necessary to suspend the process related to the selection of prescription data for the weighing target once and perform processes such as updating the patient database, and it is not necessary to reselect the prescription data for the weighing target. Also, the usual dose check based on the weight input by displaying the weight input screen 100 is skipped only when there is a clear indication of intention (i.e., the operation of the check skip button 106) that the usual dose check is not required. Therefore, the reliability of the audit can be increased. In this embodiment, when the weighing preparation button 44 is operated on the prescription content screen 40 in step S104 (S601), the processes of steps S602 to S606 are performed. Instead of this, when the selection of prescription data is received on the audit list screen 30 in S102, the processes of steps S602 to S606 may be performed. When configured in this way, in step S604, the display process of the prescription content screen 40 is temporarily stopped, and the weight input screen 100 is displayed on the display unit 15. Temporarily stopping the display process of the prescription content screen 40 is a process that prohibits the start of drug weighing. Also, the control unit 13 may pop up and display the weight input screen 100 above the audit list screen 30. Thereby, the patient's weight can be input while the prescription data for the weighing target is selected.

[0110] Next, with reference to FIG. 15, the display settings of the weight input screen will be described.

[0111] In the process shown in FIG. 13, when the control unit 13 receives an instruction to start weighing (specifically, an operation of the weighing preparation button 44), if the display condition of the body weight input screen 100 (the prescription data does not include the body weight and the patient is a pediatric patient) is satisfied, the start of weighing is prohibited and the body weight input screen 100 is displayed. Here, the display condition of the body weight input screen 100 (in other words, the prohibition condition for starting weighing) can be changed. Specifically, when the control unit 13 receives an instruction to set the display condition of the body weight input screen 100, it causes the setting screen 107 to be displayed on the display unit 15. The setting screen 107 is, for example, a pop-up display, but it may also be a screen transition.

[0112] On the setting screen 107, a button for switching the ON / OFF of the "display function of the body weight input screen" is displayed. By operating this button, the validity / invalidity of the function for displaying the body weight input screen 100 can be switched.

[0113] On the setting screen 107, a button for switching the ON / OFF of the "display of the body weight input screen for adult patients" is further displayed. By operating this button, it is possible to switch whether to display the body weight input screen 100 for adult patients (in other words, the presence or absence of S603).

[0114] On the setting screen 107, a button for switching the ON / OFF of "display the body weight input screen even if there is database registration" is further displayed. By operating this button, it is possible to switch whether to display the body weight input screen 100 when the patient's body weight is input in the patient database. Note that this setting can be further refined, for example, for pediatric patients, the body weight input screen 100 is displayed even if there is database registration, and for adult patients, the body weight input screen is not displayed if there is database registration.

[0115] The setting screen 107 further displays a button for switching the ON / OFF of the "weight input skip function (skip function for checking the usual dose)". By operating this button, it is possible to switch whether to display the check skip button 106 on the weight input screen 100. Thereby, for example, in the case where the prescription data does not include the weight, for patients who meet the display conditions of the weight input screen 100, weight input becomes essential, and the reliability of the audit can be increased.

[0116] Note that the above-described setting items are just examples, and other setting items may be provided. For example, for a preset drug, it may be possible to omit the display of the weight input screen 100, or to display only the weight input screen 100 for a preset drug.

[0117] By switching the display settings of the weight input screen 100 as described above, it is possible to perform a usual dose check with a setting according to the policy of the dispensing pharmacy.

[0118] As described above, the drug weighing device 10 of the present embodiment includes a weighing unit 11, a storage unit 14, and a control unit 13. The weighing unit 11 weighs the drug. The storage unit 14 stores dispensing data. The control unit 13 performs a usual dose check on the dispensing data stored in the storage unit 14. Before starting weighing, the control unit 13 determines whether it is possible to perform a usual dose check using the patient's weight based on whether the weight of the patient targeted by the dispensing data is set.

[0119] Thereby, since the patient's weight is required for a highly accurate usual dose check, it is possible to determine whether a highly accurate usual dose check can be performed by performing the above processing.

[0120] In the drug weighing device 10 of the present embodiment, when the control unit 13 cannot perform a usual dose check using the patient's weight, if the patient's age is less than the threshold, the start of weighing is prohibited, and if the patient's age is equal to or greater than the threshold, the start of weighing is permitted.

[0121] Thus, particularly strict measures can be taken for pediatric patients for whom the importance of normal dose checking is high.

[0122] In the medicine weighing device 10 of the present embodiment, when the control unit 13 determines that it is not possible to perform a normal dose check using the patient's weight, an input screen for inputting the patient's weight is displayed on the display unit 15.

[0123] Thus, when the patient's weight can be ascertained, a normal dose check can be performed by inputting it.

[0124] In the medicine weighing device 10 of the present embodiment, the control unit 13 displays the standard weight corresponding to the patient's age on the input screen.

[0125] Thus, information for reference can be presented.

[0126] In the medicine weighing device 10 of the present embodiment, when it is not possible to perform a normal dose check using the patient's weight, while presenting that the normal dose check cannot be executed or that input of the weight is necessary, the control unit 13 accepts a selection as to whether to skip the normal dose check. When it is instructed to skip the normal dose check, weighing is permitted.

[0127] Thus, compared with a configuration that makes the normal dose check essential, it is possible to flexibly respond to various situations.
