Summary of the Invention

Problems to be Solved by the Invention

[0004] The barcode attached to a medicine bottle or the like may be changed. If the barcode is changed and this is not reflected in the database, the drug weighing device cannot identify the drug to be weighed. Therefore, weighing may be started in a state where the drug is not identified.

[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 suppressing the start of weighing in a state where the drug is not identified. Means and Effects for Solving the Problems

[0006] The problem to be solved by the present invention is 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, a drug weighing device having the following configuration is provided. That is, the drug weighing device stores a drug database including information associating a drug with identification information capable of identifying the drug, or is accessible to the drug database. The drug weighing device includes a weighing unit and a control unit. The weighing unit weighs a drug. The control unit identifies the drug contained in the drug container based on the identification information acquired from the drug container and the identification information stored in the drug database, and selects the identified drug as the drug to be weighed. It is set that the fact that the identification information acquired from the drug container is not registered in the drug database is one of the conditions for temporarily suspending the process related to the selection of the drug to be weighed.

[0008] It is possible to suppress the start of weighing a drug when the drug to be weighed is not specified.

[0009] In the above drug weighing device, it is preferable to have the following configuration. That is, the drug weighing device includes a display unit. The display unit displays information related to dispensing data. The control unit performs a process of receiving the dispensing data. When the identification information acquired from the drug container is not registered in the drug database, the control unit causes the display unit to display the name of the drug included in the dispensing data and accepts the selection of the name of the drug. The control unit selects the drug to be weighed based on the selected drug name, and performs a process of updating the drug database by associating the drug selected as the weighing target with the identification information acquired from the drug container, and releases the temporary suspension.

[0010] Since the dispenser can select the drug to be weighed without manually inputting the name of the drug, etc., the labor can be reduced. In addition, the drug database can be updated without canceling the process related to the selection of the drug to be weighed.

[0011] In the above-described drug weighing device, when the identification information acquired from the drug container is not registered in the drug database, it is preferable that the control unit causes the display unit to display only the names of the unweighed drugs among the drugs included in the dispensing data.

[0012] For the weighed drugs, since the identification of the drugs contained in the drug container has been completed, they will not be candidates. Therefore, by not displaying the names of these drugs, the labor for the dispenser to select the name of the target drug is reduced.

[0013] In the above-described drug weighing device, it is preferable that the control unit performs a process of updating the drug database and starts weighing the drug selected as the weighing target.

[0014] Since the drug database can be updated as part of the weighing process, there is no need to perform the process related to the selection of the drug to be weighed again.

[0015] In the above-described drug weighing device, it is preferable that the control unit performs a process of updating the drug database and starts weighing the drug selected as the weighing target without acquiring the identification information of the drug container again.

[0016] Since there is no need to repeat the operation of acquiring the identification information of the drug container, the weighing can be smoothly shifted to.

[0017] In the above-described drug weighing device, it is preferable to have the following configuration. That is, when the control unit performs weighing without receiving the dispensing data, if the identification information acquired from the drug container is not registered in the drug database, the control unit accepts a selection as to whether to start weighing as an unregistered drug without registering the acquired identification information in the drug database. When it is selected to start weighing as an unregistered drug, the control unit releases the temporary stop and starts weighing.

[0018] When dispensing data is not received, the name of the drug contained in the dispensing data cannot be displayed on the display unit, and it is necessary to manually input the name of the drug and the like. Therefore, the process of updating the drug database is complicated. By weighing as an unregistered drug, the workload of the dispenser can be reduced.

[0019] In the above-mentioned drug weighing device, it is preferable that the control unit records the weighing result as an unregistered drug after the weighing is completed.

[0020] It becomes clear that an unregistered drug has been used.

Embodiments for Carrying Out the Invention

[0022] Next, embodiments of the present invention will be described with reference to the drawings.

[0023] First, the terms used in this specification will be explained.

[0024] "Drug" refers to a pharmaceutical product for treating or preventing a patient's disease, and is a prescription drug prescribed based on a prescription. A drug is a concept that includes various dosage forms, for example, powders, tablets, capsules, aqueous solutions, and ointments, etc.

[0025] "Dispensing" refers to the work of a dispenser weighing etc. a drug based on a prescription to prepare the drug.

[0026] "Prescription data" is the 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, etc. Prescription data is input into various dispensing devices and used to operate various dispensing devices. Also, the data used for dispensing among the prescription data is referred to as dispensing data. Note that dispensing data is a type of prescription data.

[0027] Drugs may be described in a prescription divided by Rp. "Rp" refers to the recipe of a prescription, and for the same Rp, for example, drugs with the same usage are described. Also, the digitized Rp is referred to as Rp data. That is, one piece of prescription data may include one or more pieces of Rp data.

[0028] Next, the outline of the dispensing system 1 will be described with reference to FIG. 1.

[0029] 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.

[0030] 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 types of 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, the management device 5 may receive the prescription information in a data format and register it. Based on the prescription information, the management device 5 creates prescription data 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 part of the medicine weighing device 10 or the packaging machine 20.

[0031] 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 verifying (or having the dispenser verify) 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.

[0032] The packaging machine 20 includes a packaging unit 21, a processing device 22, and a reading device 23. The packaging unit 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.

[0033] Next, with reference to FIGS. 1 and 2, the configuration of the medicine weighing device 10 will be described in detail.

[0034] The medicine weighing device 10 includes a weighing unit 11 for performing weighing. The weighing unit 11 weighs an object (medicine) placed on the weighing platform 11a. "Weighing" means measuring the mass value of an object (medicine), 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, a tuning fork vibration type, but other types may also be used.

[0035] A weighing container 19 is placed on the weighing platform 11a. The medicine to be weighed is put from the medicine 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 medicine weighing device 10, but the weighing container 19 is not a component of the medicine weighing device 10.

[0036] As parts related to information processing, the medicine 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 that communicates with the management device 5 or the subcontracting machine 20. The control unit 13 is a CPU that performs processing for executing a program. The storage unit 14 is a storage such as a flash memory or an SSD, which 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 the program is displayed on the display unit 15.

[0037] 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 overlapping 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, an input device of another type (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 drug 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.

[0038] 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.

[0039] Next, with reference to FIGS. 3 to 7, the weighing function will be described. Also, the auditing function will be briefly described together.

[0040] 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 of the flowchart in 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.

[0041] 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.

[0042] 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 referred to as a 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.

[0043] 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 referred to as an "un-audited state" in which the audit of all the medicines has not started. The control unit 13 displays a numbered item in parentheses next to the "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 items, the dispenser can easily grasp the remaining status of the dispensing.

[0044] In the list display area 30a, various information included in the prescription data is shown item by item using icons or character strings, etc. 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 drug. Note that instead of the dosage form icon, the type of drug may be indicated by characters. The priority is information that divides the priority of dispensing into a plurality of levels. For example, the priority may be increased according to the elapsed time from the time when the prescription was received. Also, the dispensing clerk or dispenser 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 prescriptions and temporary prescriptions. 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.

[0045] 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.

[0046] 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 multiple 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.

[0047] Each time the control unit 13 receives new prescription data from the management device 5, it updates the list display area 30a in the unfinished state and adds and displays the new prescription data. However, when the dispenser scrolls 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.

[0048] 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 a state in which 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, multiple 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 bracketed number next to "Interruption" of the interruption tab 32. This number indicates the number of pieces of prescription data in the interrupted state.

[0049] 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 is 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 a low importance level, 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.

[0050] In S102 to S105, the control unit 13 performs processing related to the selection of the 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 the prescription data in the uncompleted 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.

[0051] 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 the 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. On the other hand, in the prescription content screen, the information of all the Rp data (in particular, the drug name, usage, and total amount included in the Rp data) is displayed at the same time. 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.

[0052] 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.

[0053] In the Rp list information area 42, information on all Rp data of the selected prescription data is displayed. Note that when 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 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, in the prescription data in the interrupted state, there may be 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.

[0054] 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 dispenser operates the weighing preparation button 44.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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, or external preparation (ointment). In the weighing mode display area 52, the currently set weighing mode is displayed.

[0059] 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 (characters "not completed" 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.

[0060] 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 corresponds to a specific type (e.g., a highly potent 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.

[0061] 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 always required and can be omitted by operating the "Skip" shown in FIG. 6.

[0062] The confirmation item button 56 is a button for displaying the check result of the prescription data (the content displayed in the confirmation item area 43). The menu button 57 is a button for displaying the setting items regarding weighing.

[0063] 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 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 information on drugs (drug names, drug details (e.g., dosage forms)) with barcodes (identification information) attached to drug bottles and 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.

[0064] 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.

[0065] 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 weighed 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, the bar gets longer as the weighed value increases. 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 weighed value and the target value. In the weighed value area 63, the current weighed value is displayed numerically. In the determination area 64, the determination result of the weighed value is shown. When the weighed 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 have the dispenser collate) whether the drug included in the prescription data is weighed as per the prescription data. The display mode of the current weighed value and the target value is an example, and any of the above-described display elements may be omitted or displayed in other modes.

[0066] The confirmation button 65 is a button operated by the dispenser 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 weighed 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 weighed 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 button displayed on the weighing screen 60, it is also possible to cancel or skip the weighing of the current drug.

[0067] 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.

[0068] 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.

[0069] Next, with reference to FIGS. 8 and 9, the processing performed by the control unit 13 when the barcode (identification information) of the drug container read by the barcode reader 17 is not registered in the drug database will be described.

[0070] A "drug container" is a container for storing drugs, and the above-described drug bottle is an example of a drug container. Note that the drug container is not limited to just drug bottles, and includes, for example, drug bags and the like. Also, the barcode attached to the drug container is identification information for identifying the drug container. The control unit 13 specifies the identification information of the drug container based on the barcode reading result of the drug container by the barcode reader 17. Hereinafter, reading the barcode of the drug container to specify the identification information of the drug container is referred to as obtaining the identification information of the drug container and the like. As described above, the identification information of the drug container is registered in the drug database. That is, the identification information of the drug container is registered in the drug database in association with the drug information including the name of the drug and the like. Therefore, the identification information of the drug container is also information that can identify (specify) the drug information registered in the drug database.

[0071] Here, the barcode of the medicine container may be changed. Also, the barcode of the medicine container may not be registered in the medicine database. Therefore, the barcode reader 17 may also read a barcode that is not registered in the medicine database. In this case, in a conventional medicine weighing device, it is necessary to cancel the selection of the prescription data and return to, for example, the menu screen to update the medicine database. Then, after updating the medicine database, the dispenser needs to perform operations such as selecting the same prescription data again or obtaining the identification information of the same medicine container. In this case, the dispenser's workload is large. On the other hand, in the medicine weighing device 10 of the present embodiment, the control unit 13 can update the medicine database in the process of the process (S106 to S107) related to the selection of the medicine to be weighed. In other words, the medicine database can be updated between obtaining the identification information of the medicine container to be weighed in S106 and displaying the weighing screen 60 related to the medicine to be weighed on the display unit 15 in S107. That is, the medicine database can be updated without canceling the process related to the selection of the medicine to be weighed. That is, in order to update the medicine database, it is not necessary to reselect the prescription data to be weighed or the medicine to be weighed.

[0072] Hereinafter, the process performed by the control unit 13 will be described according to the flowchart of FIG. 8. The flowchart of FIG. 8 is a flowchart extracted from the processes performed by the control unit 13, which are processes performed according to the reading result of the barcode of the medicine container.

[0073] While the control unit 13 is displaying the weighing preparation screen 50 on the display unit 15, it determines whether or not it has obtained the identification information of the medicine container (S701). When the control unit 13 determines that it has obtained the identification information of the medicine container, it determines whether or not the obtained identification information is registered in the medicine database (S702).

[0074] When the control unit 13 determines that the acquired identification information is registered in the drug database, it determines whether the drug associated with the acquired identification information matches the drug included in the Rp data to be weighed (S703). Specifically, the control unit 13 accesses the drug database and identifies the drug contained in the drug container from the information of the drug associated with the acquired identification information. Next, the control unit 13 compares the identified drug with the drug included in the Rp data to be weighed to determine whether they match. If the identified drug matches the drug included in the Rp data, the control unit 13 identifies (selects) the drug associated with the acquired identification information as the drug to be weighed, and causes the weighing screen 60 for the drug to be displayed on the display unit 15 (S704). On the other hand, if they do not match, the control unit 13 causes an error screen to be displayed on the display unit 15 (S705). On the error screen, for example, it is displayed that the barcode of the drug container containing a drug not included in the Rp data to be weighed has been read.

[0075] When the control unit 13 determines that the acquired identification information is not registered in the drug database, it causes the registered drug selection screen 110 shown in FIG. 9 to be displayed on the display unit 15 and waits for the selection of a drug (S706). In other words, the process related to the selection of the drug to be weighed is temporarily stopped, and the registered drug selection screen 110 is displayed instead of the weighing screen 60.

[0076] Hereinafter, with reference to FIG. 9, the registered drug selection screen 110 will be described. The registered drug selection screen 110 is a screen for registering the acquired identification information in the drug database. On the registered drug selection screen 110, a notification area 111 and a drug selection column 112 are displayed.

[0077] In the notification area 111, (1) a statement indicating that the acquired identification information is not registered in the drug database and (2) a statement indicating that the acquired identification information is to be associated with the selected drug are displayed. In the drug selection column 112, a list in which candidates for the names of drugs to be associated with the acquired identification information are described is displayed. The control unit 13 causes the name of the drug included in the prescription data to be weighed (specifically, the Rp data to be weighed) to be displayed in the drug selection column 112. Preferably, the control unit 13 causes only the names of unweighed drugs among these drugs to be displayed in the drug selection column 112. As a result, the number of drug names displayed in the drug selection column 112 is reduced, making it easier for the dispenser to select the corresponding drug. Instead of the process of displaying candidates for the drug to be associated in the drug selection column 112, the control unit 13 may cause a column for the dispenser to input the name of the drug to be associated, etc. to be displayed on the registered drug selection screen 110.

[0078] Next, the control unit 13 causes the registered drug confirmation screen 115 for the drug selected from the drug selection column 112 to be displayed on the display unit 15 (S707). FIG. 9 shows the registered drug confirmation screen 115 when drug E is selected on the registered drug selection screen 110. On the registered drug confirmation screen 115, a notification area 116, a registration information area 117, a drug information instruction area 118, and a registration button 119 are displayed.

[0079] In the notification area 116, a statement for confirming that the acquired identification information is to be associated with the selected drug is displayed. In the registration information area 117, the name and barcode (identification information) of the drug to be registered in association with the drug database are displayed. The drug information instruction area 118 is an area for instructing information to be additionally registered in the drug database (for example, information on the packaging form such as roses and heat, and the standard content volume, etc.). The instruction by the dispenser may be a selection or an input. The registration button 119 is a button for instructing registration.

[0080] The display elements of the registered drug selection screen 110 and the registered drug confirmation screen 115 are examples, and some display elements may be omitted or other display elements may be added.

[0081] Next, based on whether the registration button 119 has been operated or not, the control unit 13 determines whether there is a registration instruction (S708). When the control unit 13 determines that there is a registration instruction, it associates the acquired identification information with the selected drug and registers them in the drug database (S709). As a result, the drug database is updated. At this time, the control unit 13 specifies the selected drug as the drug to be weighed. Also, due to the update of the drug database, the drug to be weighed becomes a drug already registered in the drug database, and the temporary suspension of the process related to the selection of the drug to be weighed is released. Therefore, the control unit 13 causes the display unit 15 to display the weighing screen 60 of the registered drug (S710). Thereby, the weighing of the drug to be weighed (registered drug) can be started.

[0082] In this embodiment, since the weighing screen 60 of the registered drug is displayed after the update of the drug database, the workload of the dispenser is small. However, this process is not essential, and after the update of the drug database, another screen related to the prescription data to be weighed (for example, the weighing preparation screen 50) may be displayed on the display unit 15. Even in this case, since it is not necessary to cancel the process related to the selection of the drug to be weighed, the workload of the dispenser can be reduced compared to the conventional case.

[0083] Next, with reference to FIGS. 10 to 13, the process performed by the control unit 13 when the acquired identification information is not registered in the drug database in the case of performing weighing without receiving the prescription data from the management device 5 will be described.

[0084] When weighing is performed without receiving prescription data from the management device 5, the control unit 13 registers the name of the drug specified based on the acquired identification information and the weighing value. Since the prescription data is not received, the control unit 13 does not determine whether the drug associated with the acquired identification information matches the drug included in the prescription data (Rp data). Even when weighing is performed without receiving prescription data from the management device 5, it is necessary to return to the menu screen and update the drug database, so the above-described problem (that is, the problem that the work of the dispenser becomes large when the process related to the selection of the drug to be weighed is canceled and the drug database is updated) occurs. In this regard, the drug weighing device 10 of the present embodiment can update the drug database without canceling the process related to the selection of the drug to be weighed even when weighing is performed without receiving prescription data from the management device 5.

[0085] Hereinafter, the process performed by the control unit 13 will be described with reference to the flowchart of FIG. 10. While receiving the reading of the barcode of the drug container, the control unit 13 determines whether or not the identification information of the drug container has been acquired (S801). When the control unit 13 determines that the identification information of the drug container has been acquired, it determines whether or not the acquired identification information has been registered in the drug database (S802).

[0086] When the control unit 13 determines that the acquired identification information is not registered in the drug database, it causes the display unit 15 to display the unregistered weighing confirmation screen 120 and waits for a weighing instruction (S803). In other words, the process related to the selection of the drug to be weighed is temporarily stopped, and the unregistered weighing confirmation screen 120 is displayed instead of the weighing screen 60.

[0087] Hereinafter, the unregistered weighing confirmation screen 120 will be described with reference to FIG. 11. The unregistered weighing confirmation screen 120 is a screen for confirming whether or not to perform weighing of a drug when the acquired identification information is not registered in the drug database, in other words, when the drug to be weighed cannot be specified. The unregistered weighing confirmation screen 120 displays a confirmation area 121 and a weighing button 122.

[0088] In the confirmation area 121, (1) it is displayed that the acquired identification information is not registered in the drug database, and (2) a sentence regarding confirmation of whether to start weighing without registering in the drug database is shown. The weighing button 122 is a button for instructing weighing. When the weighing button 122 is operated, the control unit 13 determines that there is an instruction for weighing (S804), releases the temporary stop of the process related to the selection of the drug to be weighed, and starts weighing (S805). Also, on the unregistered weighing confirmation screen 120 in FIG. 11, a button for returning to the prescription content screen 40 or the weighing preparation screen 50 without performing weighing is also displayed.

[0089] Note that the unregistered weighing confirmation screen 120 is a screen displayed when the prescription data is not received from the management device 5. Since it is easy to register the identification information when receiving the prescription data from the management device 5, it is essential to register in the drug database the information associating the acquired identification information with the drug.

[0090] When the control unit 13 determines that the acquired identification information is not registered in the drug database and the weighing mode corresponding to each Rp data is not set, the control unit 13 does not display the unregistered weighing confirmation screen 120 on the display unit 15, but instead displays the dosage form selection screen 125 on the display unit 15 and waits for the selection of the dosage form and the instruction for weighing.

[0091] Hereinafter, with reference to FIG. 11, the dosage form selection screen 125 will be described. On the dosage form selection screen 125, a weighing confirmation area 126 and dosage form selection buttons 127 are displayed.

[0092] In the weighing confirmation area 126, in addition to the information displayed in the confirmation area 121, a sentence for prompting the dispenser to select a dosage form is displayed. The dosage form selection button 127 is a button for selecting a dosage form, and buttons corresponding to the types of dosage forms are displayed. In FIG. 11, buttons corresponding to external preparations, aqueous preparations, and powders are displayed. Further, the dosage form selection button 127 is also a button for instructing weighing. Note that on the dosage form selection screen 125, similar to the unregistered weighing confirmation screen 120, a button for returning to the prescription content screen 40 or the weighing preparation screen 50 without performing weighing is also displayed.

[0093] When the control unit 13 determines that any one of the dosage form selection buttons 127 has been operated, the process related to the selection of the medicine to be weighed is resumed from the pause state, and a weighing mode corresponding to the dosage form corresponding to the operated button is set to start weighing. As described above, the medicine weighing device 10 has a weighing mode corresponding to the dosage form, and the screens (for example, the weighing preparation screen 50 or the weighing screen 60) are different for each weighing mode. Thus, when the weighing mode corresponding to each Rp data is not set, weighing can be started after setting the weighing mode.

[0094] Hereinafter, with reference to FIGS. 12 and 13, differences in the weighing preparation screen 50 according to the dosage form will be described.

[0095] FIG. 12 shows the weighing preparation screen 50 when the weighing mode is powder. Therefore, "powder" is displayed in the weighing mode display area 52. FIG. 13 shows the weighing preparation screen 50 when the weighing mode is aqueous preparation. Therefore, "aqueous preparation" is displayed in the weighing mode display area 52.

[0096] On the weighing preparation screen 50 when the weighing mode is powder, a filling button 59 is displayed. The filling button 59 is a button used when recording the amount of medicine filled in the medicine container. On the other hand, since the medicine is not filled in the aqueous preparation, the filling button 59 is not displayed on the weighing preparation screen 50 when the weighing mode is aqueous preparation.

[0097] On the weighing preparation screen 50 when the weighing mode is powder, an item for setting the container ID is displayed. As described above, powder is weighed using the weighing container 19, but the weighing container 19 is not used for liquid medicine. Therefore, on the weighing preparation screen 50 when the weighing mode is liquid medicine, an item for setting the container ID is not displayed.

[0098] As described above, for powder and liquid medicine, only the items used according to the dosage form are displayed. Therefore, it is easy for the dispenser to operate the medicine weighing device 10. In the above description, powder and liquid medicine are taken as examples, but for other dosage forms, such as external preparations, a different weighing preparation screen 50 is displayed. For example, since external preparations are not prescribed by the number of days, on the weighing preparation screen 50 when the weighing mode is external preparation, the item for the daily dose is not displayed. Also, even outside the weighing preparation screen 50, the screens may be different for each weighing mode. For example, on the weighing screen 60, it may be graphically represented for powder and external preparations, and milliliter representation for liquid medicine.

[0099] In addition, when the identification information has been registered in the medicine database, the control unit 13 identifies the dosage form of the medicine to be weighed from the medicine database. Thereby, the selection of the dosage form by the dispenser can be omitted. Also, the process of identifying the dosage form of the medicine from the medicine database and displaying a screen according to the dosage form of the medicine can also be performed in weighing when receiving prescription data from the management device 5.

[0100] The control unit 13 sets a weighing mode according to the dosage form and performs weighing, stores information related to the weighing, and after the weighing is completed, causes the accounting printer 18 to print an accounting form showing the information related to the weighing. When the identification information is not registered in the medicine database, the acquired identification information (barcode) is shown as the information related to the weighing. Also, the weighing value may be included in the accounting form. By managing the weighed weighing container 19 and the accounting form as a set, the information of the medicine contained in the weighing container 19 can be easily confirmed.

[0101] Next, with reference to FIGS. 14 and 15, the medicine usage history screen 130 will be described.

[0102] Figures 14 and 15 show a drug usage history screen 130. The drug usage history screen 130 is a screen for displaying drugs weighed in the past using the drug weighing device 10. For example, there may be a case where it is desired to identify a patient who has received a specific drug, and in such a case, the drug usage history screen 130 is used. When a predetermined instruction is received from the dispenser, the control unit 13 causes the drug usage history screen 130 to be displayed on the display unit 15. The drug usage history screen 130 displays a drug history display column 131 and a search button 132.

[0103] The drug history display column 131 displays a list of prescription data in a completed state. The data displayed in the drug history display column 131 is classified according to the prescription data and the drug. Therefore, even if the drugs are the same, if the patient name or the delivery time is different, they are treated as separate items. In the drug history display column 131, the items of the audit date and time, patient name, patient ID, drug name, and manufacturing number are displayed in order from the left. However, the items displayed in FIG. 14 are only examples, and other items may be displayed. The manufacturing number is also referred to as the lot number and is a number individually assigned to each lot in which the drug is manufactured. The drug history display column 131 can be sorted using these items.

[0104] The search button 132 is a button for displaying a search box 133 for searching for the usage history of a specific drug. The search box 133 displays items such as a drug selection column, manufacturing number, audit start date, and audit end date. By entering characters or numbers in these items, only the history that matches the conditions can be extracted. The items displayed in the drug history display column 131 and the search box 133 are only examples and may be different from those in FIG. 14.

[0105] By using the drug usage history screen 130, the dispenser can easily extract the history that matches the conditions. In addition, since the items in the drug history display column 131 also include patient information, it is possible to easily contact the patient.

[0106] As described above, the drug weighing device 10 of the present embodiment stores a drug database including information associating a drug with identification information capable of identifying the drug, or is accessible to the drug database. The drug weighing device 10 includes a weighing unit 11 and a control unit 13. The weighing unit 11 weighs the drug. The control unit 13 identifies the drug contained in the drug container based on the identification information acquired from the drug container and the identification information stored in the drug database, and selects the identified drug as the drug to be weighed. It is set that the fact that the identification information acquired from the drug container is not registered in the drug database is one of the conditions for temporarily suspending the process related to the selection of the drug to be weighed.

[0107] When the name of the drug to be weighed is not specified, it is possible to suppress the start of weighing the drug.

[0108] The drug weighing device 10 of the present embodiment includes a display unit 15. The display unit 15 displays information related to the dispensing data. The control unit 13 performs a process of receiving the dispensing data. When the identification information acquired from the drug container is not registered in the drug database, the control unit 13 causes the display unit 15 to display the name of the drug included in the dispensing data, and accepts the selection of the name of the drug. The control unit 13 identifies the drug to be weighed based on the selected drug name, and performs a process of updating the drug database by associating the drug selected as the weighing target with the identification information acquired from the drug container, and releases the temporary stop.

[0109] Since the dispenser can select the drug to be weighed without manually inputting the name of the drug, etc., the labor can be reduced. In addition, the drug database can be updated without canceling the process related to the selection of the drug to be weighed.

[0110] In the drug weighing device 10 of the present embodiment, when the identification information acquired from the drug container is not registered in the drug database, the control unit 13 causes the display unit 15 to display only the names of the unweighed drugs among the drugs included in the dispensing data.

[0111] Since the identification of the drug contained in the drug container has been completed for the weighed drug, it will not be a candidate. Therefore, by hiding the name of this drug, the pharmacist's effort in selecting the name of the target drug is reduced.

[0112] In the drug weighing device 10 of the present embodiment, the control unit 13 performs a process of updating the drug database and starts weighing the drug selected as the weighing target.

[0113] Since the drug database can be updated as part of the weighing process, there is no need to perform the process related to the selection of the drug to be weighed again.

[0114] In the drug weighing device 10 of the present embodiment, the control unit 13 performs a process of updating the drug database and starts weighing the drug selected as the weighing target without acquiring the identification information of the drug container again.

[0115] Since there is no need to repeat the operation of acquiring the identification information of the drug container, it is possible to smoothly shift to weighing.

[0116] In the drug weighing device 10 of the present embodiment, when performing weighing without receiving dispensing data, if the identification information acquired from the drug container is not registered in the drug database, the control unit 13 accepts a selection as to whether to start weighing as an unregistered drug without registering the acquired identification information in the drug database. If it is selected to start weighing as an unregistered drug, the control unit 13 releases the pause and starts weighing.

[0117] When dispensing data is not received, the name of the drug included in the dispensing data cannot be displayed on the display unit and the name of the drug etc. needs to be manually input, so the process of updating the drug database is complicated. Therefore, by performing weighing as an unregistered drug, the effort of the pharmacist can be reduced.

[0118] In the drug weighing device 10 of this embodiment, after completion of weighing, the control unit 13 records the weighing result as an unregistered drug.

[0119] It becomes clear that an unregistered drug has been used.
