[0010] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings to help understand the present invention. Note that the following embodiments are examples that embody the present invention and are not intended to limit the technical scope of the present invention.

[0011] 1, a mixed injection support system 1 according to an embodiment of the present invention is placed and used inside a safety cabinet 100 in which a mixed injection worker performs mixed injection work. The mixed injection support system 1 is used to improve the efficiency of mixed injection work of drugs such as anticancer drugs performed by a mixed injection worker such as a doctor or pharmacist.

[0012] The safety cabinet 100 includes a work chamber 111 partitioned by a transparent glass door 112 at the front. The glass door 112 is supported at a position where an opening 113 is formed below, and the co-infusion worker can access the work chamber 111 from the opening 113. The safety cabinet 100 is also provided with an air purifier 114 having a HEPA filter for purifying and exhausting the air within the work chamber 111. When the co-infusion support system 1 is used to perform co-infusion of non-toxic drugs such as high-calorie infusions, a clean bench or the like may be used instead of the safety cabinet 100.

[0013] As shown in FIG. 2, the mixed injection worker inserts both hands into work chamber 111 through open section 113 and performs the mixed injection work of medicines while visually checking the inside of work chamber 111. Specifically, in the mixed injection work, the mixed injection worker may perform the work of aspirating a medicinal solution from a medicine container with a syringe and injecting it into an infusion bag containing a dissolving solution such as physiological saline (saline). In addition, in the mixed injection work, the mixed injection worker may perform the work of aspirating a dissolving solution such as physiological saline from an infusion bag with a syringe and injecting it into a medicine container containing powdered medicine to dissolve the powdered medicine, and then aspirating the dissolved medicinal solution with a syringe and injecting it into the infusion bag.

[0014] In order for a mixed injection worker to properly perform the mixed injection work, it is desirable for the mixed injection worker to be aware of information such as precautions regarding the drugs used in the mixed injection work or the work steps performed in the mixed injection work. In response to this, the mixed injection support system 1 can support the mixed injection worker in properly performing the mixed injection work.

[0015] Specifically, in the mixed injection work, the mixed injection worker sequentially performs work steps such as an authentication step, a tare step, a weighing step, a photographing step, and a mixed injection step. The authentication step is a step for authenticating the medicine to be used in the mixed injection work, and is, for example, a step for reading the identification information of the medicine using the reading unit 13. The tare step is a step for pre-weighing only the equipment, such as a syringe, to be used in the mixed injection work. The weighing step is a step for weighing the syringe after the liquid medicine has been drawn into it. The photographing step is a step for taking an image that includes, within the photographing range, the syringe after the liquid medicine has been drawn into it. The mixed injection step is a step for injecting the liquid medicine in the syringe into the resulting infusion bag. The types of work steps included in the mixed injection work are not limited to those exemplified here.

The operation and display unit 22 includes an operation unit such as a mouse or keyboard and a display unit such as a liquid crystal display or an organic EL display.

[0029] The host system 3 is an electronic medical record system, an ordering system, a prescription system, or the like, and the control unit 10 can acquire from the host system 3 preparation data (prescription data) indicating the content of the mixed injection work to be performed by the mixed injection worker.

[0030] The preparation data includes patient information (patient ID, patient name, height, weight, body surface area, patient classification, pregnant / lactating classification, etc.), preparation date, drug information (drug code, drug name, YJ code, drug classification, etc.), dosage, regimen identification information, etc. Regimen identification information is information that can identify regimen information (therapy), such as therapy name (regimen name), therapy ID, or regimen ID. The preparation data may also include information such as doctor information, type of drug container (ampule containing drug solution, vial containing drug solution, vial containing powdered drug, or infusion bag, etc.), preparation content information (type and number of drug containers, syringes, and needles used in the mixed injection work, etc.), preparation procedure information (work content, dissolved drug, solvent, dissolved drug amount, solvent amount, extracted amount), administration date, prescription classification, medical department, ward, etc.

[0031] The control unit 10 controls the mixed injection support system 1 in an overall manner, and is electrically connected to components such as the memory unit 11, operation display unit 12, reading unit 13, weighing unit 14, photographing unit 15, foot switch unit 16, and communication unit 17, and is capable of sending and receiving various data or signals.

[0032] The control unit 10 is a computer having a CPU, RAM, ROM, etc. The CPU includes one or more processors that execute various types of arithmetic processing. The RAM is a volatile storage unit that is used as a temporary storage memory (work area) for the various types of processing executed by the CPU. The ROM is a non-volatile storage unit that stores information such as control programs for causing the CPU to execute various types of processing. The control unit 10 uses the CPU and the RAM to execute various types of processing in accordance with the various control programs pre-stored in the ROM or the storage unit 11.

[0033] The storage unit 11 includes storage areas such as a data area, a program area, and a master area. Note that the storage unit 11 may be provided with a plurality of storage media such as an HDD and a semiconductor memory, and the data area, the program area, and the master area may be distributed across the plurality of storage media.

[0034] The data area accumulates and stores the preparation data acquired from the host system 3. The control unit 10 may be capable of newly registering or editing the preparation data in response to a user operation. The data area also stores history information indicating the details of the mixed injection work performed by the mixed injection worker in accordance with the preparation data, in association with the preparation data. For example, the history information includes the mixed injection worker, the work start time, the work end time, various weighing results, and images taken during the mixed injection work.

[0035] The master area stores various types of master information, such as a drug master, a patient master, a ward master, a doctor master, and a pharmacist master. For example, the drug master includes information such as the drug ID, drug name, drug code, medicine bottle code, classification (dosage form: powder, tablet, liquid, topical medicine, etc.), specific gravity, drug type (ordinary medicine, anticancer drug, poison, narcotic, powerful drug, antipsychotic, therapeutic drug, etc.), compounding variations, excipient drug, precautions, type of medicine container (ampule, vial), medicine capacity per medicine container (predetermined amount), and weight of the medicine container. The medicine ID is an identification code such as a YJ code, a JAN code, or an RSS code.

[0036] The master area of ​​the storage unit 11 also stores a preparation work master in which the details of the work steps to be performed in the mixed injection work based on the pre-registered therapy, etc. are pre-registered. Then, as will be described later, the control unit 10 can set work process information indicating the details of various work steps to be performed as the mixed injection work based on the preparation data, based on the preparation data and the preparation work master. The work process information is, for example, a message indicating the details of the work to be performed in the work process and a pictogram indicating the details of the work.

[0037] Furthermore, a presentation information master D1 in which combinations of drug types and work processes are associated with presentation information is stored in the master area of ​​the storage unit 11. Specifically, as shown in Fig. 5, in the presentation information master D1, presentation information codes, drug information, presentation conditions, and presentation contents are registered in association with each other.

[0038] The presentation information code is identification information for identifying a combination of a medicine type, a work process, and presentation information. The medicine information includes medicine identification information such as a medicine code indicating the medicine type, a medicine name, and a YJ code, and a medicine classification (liquid medicine, powder medicine, etc.).

[0039] In this embodiment, a case will be described in which the presentation information can be registered in association with each drug identifiable by the drug identification information. Meanwhile, the unit of drug type according to the present invention may be a drug group including one or more drugs corresponding to one or more of the drug identification information, or a preset group unit such as the type of drug container in which the drug is contained. The concept of drug in this embodiment also includes a solvent such as saline.

[0040] The presentation conditions are conditions for determining whether or not to present the presented information, and include, for example, the patient's gender (male, female), body surface area (minimum, maximum), weight (minimum, maximum), patient classification (newborn, infant, child, elderly, adult, etc.), pregnant / lactating woman classification (not applicable, pregnant, lactating, etc.), etc. The presented content includes the presented information (message), whether or not to display the presented information, the work process corresponding to the presented information (display timing), etc.

[0041] For example, in the example shown in FIG. 5 , for presentation information code TU001, a message to be displayed when the mixing process is performed is registered as presentation information in association with the combination of the drug type "5-FU 250 mg" and the work process "mixed injection process." For example, the message may be information such as precautions about the drug used in the mixing process or the work process performed in the mixing process. Furthermore, the presence or absence of display of the presentation information is set to "1 (Yes)." Furthermore, the presentation conditions for the presentation information are registered as follows: the patient's minimum body surface area is "110" and the patient category is "pediatric." Then, as described below, when the patient's body surface area is less than "110" and the patient category is "pediatric," the control unit 10 controls the operation / display unit 12 to display the presentation information when the drug type used in the mixing process is "5-FU 250 mg" and the "mixed injection process" in the mixing process is performed.

[0042] The program area stores a mixed injection assistance program for causing the control unit 10 to execute the mixed injection assistance process described below. The program area may also store other application programs such as an operating system and browser software.

[0043] The control unit 10 includes various processing units such as a first presentation processing unit 101, a second presentation processing unit 102, a setting processing unit 103, and a switching processing unit 104. The control unit 10 executes various processes in accordance with the mixed injection support program, thereby functioning as the first presentation processing unit 101, the second presentation processing unit 102, the setting processing unit 103, and the switching processing unit 104. In another embodiment, some or all of the processing units included in the control unit 10 may be configured with electronic circuits.

[0044] The first presentation processing unit 101 presents work process information indicating the content of one or more work processes in the mixed injection work of medicines. The second presentation processing unit 102 presents the presentation information, which is set in advance in association with a combination of a medicine type and a work process in the mixed injection work, on the operation display unit 12 at a preset timing. The first presentation processing unit 101 and the second presentation processing unit 102 present the work process information and the presentation information to the mixed injection worker by various output methods, such as display, audio playback, printing, and data transmission. In this embodiment, an example will be described in which the work process information and the presentation information are presented to the mixed injection worker by displaying them on the operation display unit 12.

[0045] The setting processing unit 103 sets either or both of the presentation information and the timing corresponding to the combination in response to a user operation. Specifically, the setting processing unit 103 can execute a master editing process, including addition, modification, or deletion of the presentation information master D1, in response to a user operation.

[0046] Here, an example of the master editing process will be described. Note that, although the master editing process executed by the setting processing unit 21 of the setting terminal 2 will be described here, a similar master editing process may be executed by the setting processing unit 103 of the control unit 10. For example, a setting monitor and setting operation unit (not shown) may be connected to the control unit 10 of the mixed injection support system 1, and the setting processing unit 103 of the control unit 10 may execute the master editing process using the setting monitor and the setting operation unit. Note that the setting monitor is larger in size than the operation display unit 12, and the setting operation unit is a keyboard, a mouse, or the like.

[0047] First, in response to a predetermined operation by the user on the operation display unit 22, the setting processing unit 21 reads out the presentation information master D1 from the storage unit 11 of the mixed injection support system 1, and displays a setting screen P1 (see FIG. 6) for editing the presentation information master D1 on the operation display unit 22. The predetermined operation includes an operation for searching for and selecting the type of medicine to be edited, and an operation for starting editing the presentation information master D1 corresponding to the type of medicine, and the setting processing unit 21 displays the setting screen P1 for editing information in the presentation information master D1 corresponding to the selected type of medicine.

[0048] Specifically, FIG. 40 shows an example of a reference screen P0 for referencing the contents of the presentation information master D1. As shown in FIG. 40, display areas A1 to A5 are displayed on the reference screen P0. In the display area A1, one or more types of drugs to be searched for can be selected. In the display area A2, search conditions can be entered for the drugs, combination drugs, therapies, procedures / routes, patient information, or presentation information (partial match) to be searched for. Here, the control unit 10 can select either the search method for the display area A1 or the display area A2 on the reference screen P0 in response to a user operation. Furthermore, in the display area A3, it is possible to select the work process to be searched for and whether to narrow the search to anticancer drugs.

[0049] When the operation key K1 for starting a search is operated, the control unit 10 extracts search result data that matches the search conditions entered in the currently selected display area A1 or display area A2 and the content entered in display area A3 from the presentation information master D1. Specifically, the control unit 10 displays combinations of drug types extracted as the search result data and presentation conditions (described below) in the display area A4. Here, when a row of a combination of a drug type and presentation conditions is selected in the display area A4 by a user operation, the control unit 10 displays a list of the presentation information registered in association with the combination in the display area A5. Furthermore, when the operation key K2 is operated with a row of a combination of a drug type and presentation conditions selected in the display area A4, the control unit 10 displays a setting screen P1 for editing the presentation information corresponding to the drug type in the combination on the operation display unit 12.

[0050] As shown in Figure 6, the setting screen P1 displays a display area A11 in which information about the drug to be edited is displayed, a display area A12 for setting the presentation conditions, a display area A13 for setting the presentation content, and a display area A14 in which reference information is displayed.

[0051] Furthermore, the setting screen P1 displays operation keys K11 to K13 for accepting user operations. In response to operation of the operation key K11, the setting processing unit 21 registers the input content of the setting screen P1 in the presentation information master D1 and stores the presentation information master D1 in the storage unit 11 of the mixed injection support system 1. In addition, in response to operation of the operation key K12 or K13, the setting processing unit 21 inserts or deletes a line in the display area A12 or A13 selected as the operation target.

[0052] In the display area A11, the drug code, drug name, and YJ code are displayed as drug identification information corresponding to the type of drug to be edited, and the classification of the drug (liquid drug, powder drug, etc.) is also displayed.

[0053] Display area A12 displays presentation conditions for determining whether or not to display the presentation information corresponding to the type of drug being edited, and setting processing unit 21 edits the presentation conditions in response to user operations on display area A12. For example, the presentation conditions include conditions such as combination drug, therapy, procedure / route, gender, minimum body surface area, maximum body surface area, minimum weight, maximum weight, patient category, and pregnant / lactating category. In the example shown in FIG. 6, the top row of display area A12 displays the following registered presentation conditions: combination drug is "saline," therapy is "Therapy A," procedure / route is "intravenous infusion," minimum body surface area is "110," and patient category is "pediatric."

[0054] The display area A13 displays a display / non-display setting area A131, a process setting area A132, and a presentation information setting area A133 for each piece of presentation information to be registered in association with a combination of a drug type and a work process. The setting processing unit 21 displays, in the display area A13, the presentation information to be registered in association with the presentation condition corresponding to a row selected in the display area A12. Specifically, the control unit 10 can register one or more pieces of presentation information in association with one or more presentation conditions selected in the display area A12 in response to a user operation in the display area A13. For example, when the presentation information is input into the display area A13 while multiple presentation conditions are selected in the display area A12, the presentation information is registered in association with each of the presentation conditions. Furthermore, when multiple pieces of presentation information are input into the display area A13 while one presentation condition is selected in the display area A12, the multiple pieces of presentation information are registered in association with the presentation condition. When a plurality of pieces of presentation information are registered in the display area A13, the display order of the rows corresponding to each piece of presentation information in the display area A13 becomes the priority order when a list of the presentation information is displayed, as will be described later. The setting processing unit 21 can change the display order of the rows corresponding to each piece of presentation information in the display area A13 (priority order of the presentation information) in response to a user operation.

[0055] In response to a user operation in the display / non-display setting area A131, the setting processing unit 21 switches between displaying and not displaying the presentation information set in the same row as the display / non-display setting area A131. In response to an operation in the process setting area A132, the setting processing unit 21 sets a work process to be associated with the presentation information set in the same row as the process setting area A132. For example, in response to an operation in the process setting area A132, the setting processing unit 21 displays one or more pre-set work processes as selection candidates in a pull-down menu, and sets a work process selected from the pull-down menu as the work process to be associated with the presentation information.

[0056] In addition, in the process setting area A132, it is also possible to select "No Designation," which does not specify a work process. In this case, the corresponding work process column is left blank in the presentation information master D1 shown in FIG. 5. The presentation information for which the corresponding work process is set to "No Designation" is displayed only in the list of presentation information displayed at the start and end of the mixed injection work, as described below, but is not displayed at the start of each work process in the mixed injection work. In this way, in the presentation information master D1, "No Designation" can be set as one type of work process in the mixed injection work. When the presentation information is set in association with this combination of "No Designation" and a drug type, the second presentation processing unit 102 can present the presentation information at a predetermined timing. In other words, the work process in the present invention may include not only the process actually performed in the mixed injection work, but also a virtual process that can be set as data in the work process item in the presentation information master D1, etc.

[0057] Furthermore, the setting processing unit 21 accepts input of messages such as precautions to be registered as presentation information corresponding to the combination of the type of drug currently being edited and the work process set in the process setting area A132 in the presentation information setting area A133. The setting processing unit 21 can also reflect the contents of the display area A14 in the display area A13, as will be described later.

[0058] The display area A14 displays the contents of preparation data (or prescription data) previously input to the mixed injection support system 1 as selection candidates for various information to be set in the display area A13. For example, the setting processing unit 21 accumulates and stores the details of the mixed injection work, patient information, comments, etc., indicated in the preparation data input to the mixed injection support system 1 as the selection candidates and displays them in the display area A14. In particular, the setting processing unit 21 acquires the difference between the presentation information master D1 and each of the preparation data. If the preparation data contains a comment that is not registered as the presentation information in the presentation information master D1, the setting processing unit 21 stores the comment in the storage unit 11 as a candidate for the presentation information to be displayed in the display area A14. Furthermore, among the comments that are not registered as the presentation information in the presentation information master D1, only comments that partially match preset keywords may be stored as candidates for the presentation information. The process of storing the presentation information candidates by the setting processing unit 21 is automatically performed at preset timing or intervals. Furthermore, the display area A14 displays an operation key K14 for reflecting the contents of the display area A14 in the display area A13. When one of the selection candidates is selected in the display area A14 and the operation key K14 is operated, the setting processing unit 21 reflects the content of the selected selection candidate in the presented information in the display area A13. This allows the user to easily set the presented information in the display area A13. Note that, among the selection candidates accumulated based on previously input preparation data, only selection candidates accumulated based on preparation data in which the type of medicine displayed in the display area A11 was used in a mixed injection operation may be displayed in the display area A14. Furthermore, when at least a portion of the selection candidates has been input in the display area A12, only the selection candidates that match the content of the input presentation conditions may be displayed in the display area A14.

[0059] Then, after information is input into the display areas A12 and A13, when the operation key K11 is operated, the setting processing unit 21 registers the presentation information displayed in the display area A13 in the presentation information master D1 in association with the combination of the drug type displayed in the display area A11 and the work process displayed in the display area A13. Note that the setting processing unit 21 may display a preview screen or the like of the presentation information actually displayed on the mixture injection support screen P2 (described later) based on the content input on the setting screen P1 during or after the registration of the presentation information master D1 using the setting screen P1. For example, the setting processing unit 21 may sequentially display a series of mixture injection support screens P2, which are displayed sequentially by the mixture injection support process (described later), as the preview screen.

[0060] The switching processing unit 104 switches the operation mode of the mixed injection assistance system 1 between beginner mode and expert mode. The beginner mode is an example of a first operation mode in which the presented information is presented at a preset timing, and is an operation mode used, for example, when the mixed injection worker has a relatively low level of proficiency. The expert mode is an example of a second operation mode in which the presented information is not presented, and is an operation mode used, for example, when the mixed injection worker has a relatively high level of proficiency. Specifically, the switching processing unit 104 can switch the operation mode of the mixed injection assistance system 1 in response to a user operation. Furthermore, the switching processing unit 104 may automatically switch the operation mode of the mixed injection assistance system 1 in response to the identification information of the mixed injection worker currently logged in to the mixed injection assistance system 1 or the proficiency (skill level) previously associated with the mixed injection worker.

[0061] [Mixed Injection Support Processing: Beginner Mode] Hereinafter, with reference to Fig. 7, a description will be given of the mixed injection support process executed by the control unit 10 when the operation mode of the mixed injection support system 1 is the beginner mode. For example, the mixed injection support process is executed by the control unit 10 when a mixed injection worker logs into the mixed injection support system 1 by inputting an ID, password, etc. using the operation display unit 12 and selects the beginner mode as the operation mode. Below, an example of the mixed injection support screen P2 displayed on the operation display unit 12 during the mixed injection support process will be described with reference to Figs. 9 to 29. Note that, as shown in Figs. 9 to 29, for convenience of explanation, different reference numerals will be used to denote the various mixed injection support screens P2 displayed in sequence during the mixed injection support process.

[0062] <Step S10> In step S10, the control unit 10 accepts the selection of preparation data to be processed. Specifically, when the reading unit 13 reads preparation data identification information written on a preparation slip, prescription, or the like, the control unit 10 determines that the preparation data corresponding to the preparation data identification information has been selected as the preparation data to be processed. The control unit 10 may also display a list screen P20 (see FIG. 41) of preparation data for which mixed injection work has not yet been performed, and select the preparation data to be processed from the list screen in response to a user operation. As shown in FIG. 41, the control unit 10 searches for and displays the preparation data on the list screen P20 based on specified search conditions. The control unit 10 can also switch the operation mode of the mixed injection support system 1 between beginner mode, expert mode, and the like in response to the operation of the operation key K201 on the list screen P20. The control unit 10 presents the current operation mode of the mixed injection support system 1 to the user by displaying the current operation mode in the display area A201 of the list screen P20. Once the preparation data is selected, the process proceeds to step S11. Hereinafter, the prepared data selected as the processing target in step S10 may be referred to as the target prepared data.

[0063] <Step S11> In step S11, the control unit 10 sets the content (work process information) of the mixed injection work to be performed based on the target preparation data based on the target preparation data and the preparation work master. Note that the control unit 10 when executing the process of generating work process information based on the target preparation data and the preparation work master is an example of a generation processing unit according to the present invention. Also, the first presentation processing unit 101 may execute step S11, in which case the first presentation processing unit 101 is an example of a generation processing unit according to the present invention. Note that the content of the mixed injection work may be included in the target preparation data, and in this case, the control unit 10 sets the content of the mixed injection work included in the target preparation data as the content of the mixed injection work to be performed based on the target preparation data. Note that when the preparation data includes the content of the mixed injection work, the content of the mixed injection work is set, for example, in the upper system 3, based on the prescription data corresponding to the target preparation data and the preparation work master.

[0064] In the present embodiment, as shown in FIG. 8, an example will be described in which three preparation procedures are set as the contents of the mixed injection work: a first preparation procedure "preparing 500 mL of saline," a second preparation procedure "preparing 250 mg of 5-FU injection," and a third preparation procedure "mixing into 500 mL of saline." Also, as shown in FIG. 8, in the first preparation procedure (preparing 500 mL of saline), an authentication process, a tare process, a weighing process, and an imaging process are executed in order. Similarly, in the second preparation procedure (preparing 250 mg of 5-FU injection), an authentication process, a tare process, a weighing process, and an imaging process are executed in order. Also, in the third preparation procedure (mixing into 500 mL of saline), a mixed injection process is executed. In the mixed injection support process, the mixed injection support screen P2 (P23 to P28) shown in Figures 11 to 16 is displayed in order for the first preparation procedure, the mixed injection support screen P2 (P31 to P39) shown in Figures 17 to 25 is displayed in order for the second preparation procedure, and the mixed injection support screen P2 (P41 to P43) shown in Figures 26 to 28 is displayed in order for the third preparation procedure. After that, when the mixed injection work is completed, the mixed injection support screen P2 (P44) shown in Figure 29 is displayed.

[0065] <Step S12> In step S12, the control unit 10 displays a mixed injection support screen P21 (see FIG. 9) on which the contents of the target preparation data and the like are displayed on the operation display unit 12. As shown in FIG. 9, the mixed injection support screen P21 displays display areas A20 to A23 and the like.

[0066] Display area A20 displays a character string that outlines the display content of each mixed injection support screen P2, such as mixed injection support screen P21, that is displayed in sequence on operation display unit 12. In the example shown in Fig. 9, display area A20 displays "Prescription Contents," which indicates that the display content of mixed injection support screen P21 is the content of preparation data.

[0067] The contents of the target preparation data are displayed in the display area A21. In the example shown in Fig. 9, various information such as the name of the treatment, the type of medicine, the dosage, the dispensed amount, and the usage method are displayed in the target preparation data.

[0068] The display area A22 displays the types and quantities of medicines to be used in the mixed injection work based on the target preparation data. In the example shown in Fig. 9, the display area A22 displays that three bottles of "5-FU injection 250 mg" medicine and one bag of "saline 500 mL" medicine are required.

[0069] Display area A23 displays the type and quantity of equipment used in the mixed injection operation based on the target preparation data. In the example shown in Figure 9, display area A23 displays two "20 mL syringes" and the fact that a "closed device" is "present." Note that one of the two "20 mL syringes" is used to extract medicinal liquid from "500 mL of normal saline," and an extraction container or the like may be used instead of the syringe.

[0070] In other embodiments, the mixed injection support screen P21 may display other information such as the name of the mixed injection operator (pharmacist name), inspector name, medical department, ward, start date of medication, doctor name, patient name (patient ID), age, and gender.

[0071] Furthermore, operation keys K21 to K23 are displayed on each of the mixed injection support screens P2, such as the mixed injection support screen P21, and the control unit 10 accepts touch operations of the operation keys K21 to K23 on the operation display unit 12 and executes corresponding processes. Furthermore, the control unit 10 also determines that the operation key K21 has been operated when the first foot switch 161 has been operated. Similarly, the control unit 10 determines that the operation key K22 has been operated when the second foot switch 162 has been operated, and determines that the operation key K23 has been operated when the third foot switch 163 has been operated.

[0072] Specifically, when the mixed injection support screen P21 is displayed and the mixed injection worker checks the mixed injection support screen P21 and operates the operation key K23 or the third foot switch 163, the control unit 10 transitions the processing to step S13.

[0073] <Step S13> In step S13, the control unit 10 displays a mixed injection support screen P22 (see FIG. 10) on the operation display unit 12. The mixed injection support screen P22 displays a list (display area A31) of the presentation information, such as precautions for the mixed injection work based on the target preparation data. At this time, the control unit 10 displays the presentation information registered in the presentation information master D1 in the display area A31 in the order of priority (the display order in the display area A13 in FIG. 6) corresponding to the presentation information. When the operation key K23 or the third foot switch 163 is operated, the control unit 10 shifts the process to step S14. The process of presenting the list of presentation information at the preset start timing of the mixed injection work is an example of a second presentation step, and is executed by the second presentation processing unit 102 of the control unit 10.

[0074] Specifically, the control unit 10 extracts from the presentation information master D1 all of the presentation information corresponding to the combination of the type of drug used in the target preparation data and the work process performed in the mixed injection work based on the target preparation data. The control unit 10 then identifies, from the extracted presentation information, presentation information for which the content of the target preparation data satisfies the presentation conditions corresponding to the presentation information and for which the display status is set to "1 (Yes)," and displays a list of the identified presentation information on the mixed injection support screen P22. This allows the mixed injection worker to grasp the presentation information, such as precautions for the entire mixed injection work, at the start of the mixed injection work based on the preparation data. On the other hand, among the extracted presentation information, presentation information for which the content of the target preparation data does not satisfy the presentation conditions corresponding to the presentation information, or presentation information for which the display status is set to "0 (No)," is not displayed on the mixed injection support screen P22.

[0075] For example, in the example shown in the presentation information master D1 of FIG. 5, the presentation information is set for each combination of the drug type "5-FU 250 mg" and the work processes "authentication process," "weighing process," "photography process," "mixed injection process," and "unspecified." Furthermore, for the combination of "5-FU 250 mg" and the "mixed injection process," the presentation conditions are set as a minimum body surface area of ​​"110" and a patient category of "pediatric." Therefore, when the target preparation data includes "5-FU 250 mg," the mixed injection work based on the target preparation data includes a "mixed injection process," the body surface area of ​​the patient corresponding to the target preparation data is less than "110," and the patient category of the patient is "pediatric," i.e., when the presentation conditions are met, the presentation information corresponding to the combination of "5-FU 250 mg" and the "mixed injection process" is displayed. On the other hand, even if the target preparation data includes "5-FU 250 mg" and the mixing work based on the target preparation data includes a "mixing process," if the body surface area of ​​the patient corresponding to the target preparation data is "110" or more, or if the patient's patient category is not "pediatric," i.e., if the presentation conditions are not met, the presentation information corresponding to the combination of "5-FU 250 mg" and the "mixing process" will not be displayed.

[0076] In the example shown in the presentation information master D1 of FIG. 5, the message "Please prepare all medicines and equipment before starting preparation work" is registered as the presentation information for "5-FU 250 mg" for which the work process is "not specified." The control unit 10 displays the presentation information for which the corresponding work process is set to "not specified" in the presentation information master D1 in the list on the mixed injection support screen P22 and the mixed injection support screen P44 described later, but does not display it at the start of each work process. Note that in this embodiment, an example will be described in which the presentation information registered in association with the "not specified" work process is presented at a preset timing, such as the start and end of the mixed injection work. Meanwhile, as another method, a confirmation process for confirming the contents of the target preparation data displayed on the mixed injection support screen P21 of FIG. 9 or a confirmation process for confirming the mixed injection results on the mixed injection support screen P44 (see FIG. 29) described later may be registered in the presentation information master D1 as an example of the work process. When the confirmation process is registered in the presentation information master D1 in association with a combination of a medicine type and the presentation information, the control unit 10 can display the presentation information on the mixed injection support screen P2 at a preset timing such as the start or end of the confirmation process. Furthermore, the presentation information master D1 may be capable of registering multiple timings as the display timing of the presentation information associated with one combination.

[0077] <Step S14> In step S14, the control unit 10 sequentially selects the preparation procedures included in the mixed injection work based on the target preparation data as the execution target. Note that, hereinafter, the preparation procedure selected here may be referred to as the target preparation procedure.

[0078] Specifically, when the mixed injection work includes three preparation procedures, namely, the first preparation procedure (preparation of 500 mL of saline), the second preparation procedure (preparation of 250 mg of 5-FU injection), and the third preparation procedure (mixing with 500 mL of saline), the control unit 10 selects each of the preparation procedures in turn as the preparation procedure to be executed each time step S14 is executed. Then, the control unit 10 displays the selected preparation procedures in an identifiable manner on the mixed injection support screen P23 (see FIG. 11). For example, when step S14 is executed for the first time, the first preparation procedure "preparation of 500 mL of saline" selected first is displayed in an identifiable manner (enclosed in a thick line) as shown in FIG. When step S14 is executed for the second time, the second preparation procedure "Preparation of 250 mg of 5-FU injection" is displayed in a distinguishable manner as shown in FIG. 17, and when step S14 is executed for the third time, the third preparation procedure "Mix with 500 mL of saline" is displayed in a distinguishable manner as shown in FIG. 26.

[0079] <Step S15> In step S15, the control unit 10 sequentially selects the work steps included in the target preparation procedure as work steps to be executed. Note that, hereinafter, the work steps selected here may be referred to as target work steps.

[0080] Specifically, in this embodiment, an example will be described in which the first preparation procedure includes an authentication step, a tare step, a weighing step, and a photographing step as work steps, the second preparation procedure includes an authentication step, a tare step, a weighing step, and a photographing step as work steps, and the third preparation procedure includes a co-injection step as a work step. For example, when the target preparation procedure is the first preparation procedure or the second preparation procedure, the control unit 10 selects the authentication step, tare step, weighing step, and photographing step as work steps to be executed in this order each time step S15 is executed.

[0081] <Step S16> In step S16, the control unit 10 determines whether or not the presentation information corresponding to the target work process exists. Specifically, the control unit 10 extracts presentation information corresponding to the combination of the target work process and the type of drug used in the target work process from the presentation information master D1. Then, if the extracted presentation information contains presentation information in which the content of the target preparation data satisfies the presentation condition of the presentation information and the display status is set to "Yes," the control unit 10 determines that presentation information corresponding to the target work process exists. Here, if the control unit 10 determines that presentation information corresponding to the target work process exists (S16: Yes), the control unit 10 proceeds to step S17.

[0082] On the other hand, if presentation information corresponding to the combination of the target work process and the type of drug used in the target work process is not registered in the presentation information master D1, the control unit 10 determines that presentation information corresponding to the target work process does not exist. Furthermore, even if presentation information corresponding to the combination of the target work process and the type of drug used in the target work process is extracted from the presentation information master D1, the control unit 10 determines that presentation information corresponding to the target work process does not exist if the content of the target preparation data does not satisfy the presentation condition corresponding to the presentation information or if the display / non-display setting for the presentation information is set to "none." If the control unit 10 determines that presentation information corresponding to the target work process does not exist (S16: No), the control unit 10 proceeds to step S18.

[0083] <Step S17> In step S17, the control unit 10 displays the presentation information corresponding to the target work process on the co-injection support screen P2 (see FIG. 18, etc.) of the operation display unit 12. That is, the control unit 10 presents the presentation information associated with the combination of the target work process and the type of drug to the co-injection worker at the start of the target work process. Then, when the operation key K23 or the third foot switch 163 is operated, the control unit 10 shifts the processing to step S18. Note that this processing of presenting the presentation information at the start of the predetermined target work process is an example of a second presentation step, and is executed by the second presentation processing unit 102 of the control unit 10.

[0084] Furthermore, in this embodiment, a case where the start timing of the target work process is set in advance as the display timing of the presentation information corresponding to the target work process is described. However, the display timing may be set to the start or end of the target work process for each piece of presentation information. In this embodiment, a case where the display timing of the presentation information is set to the start or end of the work process by specifying the work process associated with the presentation information is described as an example. However, the display timing of the presentation information may be set separately from the work process corresponding to the presentation information. Furthermore, the display timing of each piece of presentation information may be set based on the work process, such as the start or end of the work process, or may be set based on the co-infusion work, such as the start or end of the co-infusion work. Furthermore, the presentation information may be displayed on the operation / display unit 12 at the same timing as the work process information of the target work process in step S18, in which the work process information of the target work process is displayed. In addition, the presented information may be presented to the mixed injection worker by being played back as audio at the same time that the work process information for the target work process displayed in step S18 is displayed on the operation display unit 12.

[0085] <Step S18> In step S18, the control unit 10 displays the work process information corresponding to the target work process on the mixed injection support screen P2 of the operation display unit 12. Thereafter, when the mixed injection operator performs the target work process and operates the operation key K23 or the third foot switch 163, the control unit 10 shifts the processing to step S19. Note that the processing of presenting the work process information in this manner is an example of a first presentation step, and is executed by the first presentation processing unit 101 of the control unit 10.

[0086] Specifically, when the target work step is the authentication step, as shown in FIG. 12, a mixed injection support screen P24 is displayed on the operation display unit 12. The mixed injection support screen P24 displays work step information, such as pictograms and messages, for prompting the user to authenticate 500 mL of saline. The mixed injection worker then performs an operation to have the reading unit 13 read the code information for 500 mL of saline. After that, when the reading unit 13 reads the code information and the operation key K23 or the third foot switch 163 is operated, the control unit 10 shifts the process to step S19. The control unit 10 stores the results of the reading in the memory unit 11 as historical information for the mixed injection work based on the target preparation data, in association with the target preparation data. 12, 13, 14, 16, 19, 20, 22, 25, 28, etc., when the operation key K22 is operated while "Prescription / Caution" is displayed on the operation key K22, the control unit 10 displays a list of the presented information that was displayed in the display area A31 of the mixed injection support screen P21 (see FIG. 10). For example, when the operation key K22 is operated while the mixed injection support screen P24 shown in FIG. 12 is displayed, the control unit 10 displays the list of the cautions that were displayed in the display area A31 on the mixed injection support screen P22 of FIG. 10 in the display area A24, as shown in FIG. 42. When the list of cautions does not fit in the display area A31, the control unit 10 can change the cautions to be displayed by scrolling the display area A31 in response to a scroll operation in the display area A31. 12 in response to operation of the operation key K22 on the mixed injection support screen P22 of FIG. 42.

[0087] If the target work process is the tare process, as shown in FIG. 13, a mixed injection support screen P25 is displayed on the operation display unit 12. The mixed injection support screen P25 displays work process information such as pictograms and messages prompting the weighing unit 14 to tare the syringe, as shown in FIG. 13. This prompts the mixed injection worker to place an empty syringe on the placement section 141 of the weighing unit 14 and perform an operation to start tare-weighting the syringe on the weighing unit 14. After that, when tare-weighting by the weighing unit 14 is completed and the operation key K23 or the third foot switch 163 is operated, the control unit 10 shifts the processing to step S19. The control unit 10 stores the result of tare-weighting performed here in the memory unit 11 as history information of the mixed injection work based on the target preparation data, in association with the target preparation data.

[0088] If the target work step is the weighing step, as shown in FIG. 14, the operation display unit 12 displays a mixed injection support screen P26, which displays work step information such as a message prompting the weighing unit 14 to measure. The mixed injection support screen P26 also displays "15.72 g" as a target weighing value corresponding to "15 mL," the amount of 500 mL of saline to be drawn. The mixed injection worker then draws "15 mL" of 500 mL of saline using a syringe, places the syringe on the weighing unit 14's mounting portion 141, and weighs it so that the weight of the syringe matches the target weighing value. If the weighing result by the weighing unit 14 falls within a predetermined error range with respect to the target weighing value and the operation key K23 or the third foot switch 163 is operated, the control unit 10 proceeds to step S19. The control unit 10 stores the results of the measurement here in the storage unit 11 as history information of the mixed injection work based on the target preparation data in association with the target preparation data.

[0089] If the target work process is the photography process, as shown in FIG. 15, a mixed injection support screen P27 is displayed on the operation display unit 12. The mixed injection support screen P27 displays work process information, such as a message prompting the photographer 15 to take a photograph. An image captured by the photographer 15 is displayed on the mixed injection support screen P27. The mixed injection worker then operates the operation key K23 or the third foot switch 163 while referring to the mixed injection support screen P27, thereby capturing an image of the mounting section 141 of the weighing unit 14 and the syringe or the like placed on the mounting section 141 with the photographer 15. Once the image has been captured, the control unit 10 displays a mixed injection support screen P28 on the operation display unit 12, as shown in FIG. 16, displaying the image captured by the photographer 15. Thereafter, when the operation key K23 or the third foot switch 163 is operated, the control unit 10 transitions the process to step S19. The control unit 10 stores the image taken here in the storage unit 11 as history information of the mixed injection work based on the target preparation data in association with the target preparation data.

[0090] <Step S19> In step S19, the control unit 10 determines whether the target preparation procedure has been completed. If the target preparation procedure has been completed (S19: Yes), the control unit 10 proceeds to step S20. If the target preparation procedure has not been completed (S19: No), the control unit 10 returns to step S15. As a result, the control unit 10 similarly executes the processes of steps S15 to S18 until all work steps in the target preparation procedure have been completed.

[0091] <Step S20> In step S20, the control unit 10 determines whether the mixed injection work based on the target preparation data has been completed. If the mixed injection work has been completed (S20: Yes), the control unit 10 proceeds to step S21, and if the mixed injection work has not been completed (S20: No), the control unit 10 returns to step S14. As a result, the control unit 10 similarly executes the processes of steps S14 to S19 until all preparation procedures in the mixed injection work have been completed.

[0092] Specifically, when the first preparation procedure is completed, the second preparation procedure is then selected as the target preparation procedure, and in step S14, "Preparation of 250 mg 5-FU injection" of the second preparation procedure is displayed in an identifiable manner, as shown in Fig. 17. Thereafter, in steps S15 to S18, the authentication step, tare step, weighing step, and photography step included in the second preparation procedure are selected in order as target work steps, and the presented information and the work step information are displayed in order.

[0093] For example, if the authentication step is selected as the target work step and the presentation information corresponding to the combination of the authentication step and the type of drug is registered, a mixed injection support screen P32 (see FIG. 18) displaying the presentation information corresponding to the combination is displayed, and then a mixed injection support screen P33 (see FIG. 19) displaying the work step information of the authentication step is displayed on the operation display unit 12. As shown in FIG. 19, on the mixed injection support screen P33, the fact that three bottles of the drug "5-FU injection 250 mg" are required is expressed as "0 / 3," and each time the reading unit 13 reads the code information of the drug, this is updated to "1 / 3," "2 / 3," and "3 / 3." When the code information is authenticated three times, the next tare step is selected as the target work step.

[0094] Furthermore, if the tare process is selected as the target work process and the presentation information corresponding to the combination of the tare process and the type of medicine is not registered, the presentation information is not displayed, and the mixed injection support screen P34 (see Figure 20) displaying the work process information for the tare process is displayed on the operation display unit 12.

[0095] Furthermore, when the weighing process is selected as the target work process and the presentation information corresponding to the combination of the weighing process and the type of drug is registered, a mixed injection support screen P35 (see Figure 21) displaying the presentation information corresponding to the combination is displayed, and then a mixed injection support screen P36 (see Figure 22) displaying the work process information for the weighing process is displayed on the operation display unit 12.

[0096] In addition, when the photographing process is selected as the target work process and the presentation information corresponding to the combination of the photographing process and the type of drug is registered, a mixed injection support screen P37 (see Figure 23) displaying the presentation information corresponding to the combination is displayed, and then mixed injection support screens P38 and P39 (see Figures 24 and 25) displaying the work process information for the photographing process are displayed on the operation display unit 12.

[0097] Thereafter, when the second preparation procedure is completed, the third preparation procedure is selected as the target preparation procedure, and in step S14, "mix with 500 mL of normal saline" of the third preparation procedure is displayed in an identifiable manner, as shown in Fig. 26. Thereafter, in steps S15 to S18, the mixed injection step included in the third preparation procedure is selected as the target work step, and the presented information, the work step information, and the like are displayed.

[0098] Specifically, when the co-infusion process is selected as the target work process and the presentation information corresponding to the co-infusion process and the type of drug is registered, a co-infusion support screen P42 (see Figure 27) displaying the presentation information corresponding to the combination is displayed, and then a co-infusion support screen P43 (see Figure 28) displaying the work process information for the authentication process is displayed on the operation display unit 12.

[0099] After the mixed injection work is completed, a photographing process is performed to photograph the result of the mixed injection work, such as an infusion bag, and the photographed image taken in the photographing process may be stored as history information corresponding to the target preparation data. The control unit 10 can set in advance whether or not to photograph the result in response to a user operation.

[0100] <Step S21> In step S21, the control unit 10 causes the operation display unit 12 to display a mixed injection support screen P44 (see FIG. 29) on which a list of the presented information, such as the result of the mixed injection work based on the target preparation data and precautions for the mixed injection work, is displayed. Note that the process of presenting the list of presented information at the preset end timing of the mixed injection work is an example of a second presentation step, and is executed by the second presentation processing unit 102 of the control unit 10.

[0101] 29, on the mixed injection support screen P44, the results of the mixed injection work, such as whether or not the photographing step was performed, whether or not the authentication step was performed, and the measurement results in the measurement step, corresponding to each type of medicine, are displayed in a display area A441. Also, on the mixed injection support screen P44, a list of the presentation information that is the same as that on the mixed injection support screen P22 displayed in step S13 is displayed in a display area A442. That is, the display area A442 displays a list of presentation information that is registered in the presentation information master D1 in association with combinations of the types of medicines used in the mixed injection work and the work steps performed in the mixed injection work.

[0102] In this embodiment, the list of presented information displayed on the mixture injection support screen P22 in step S13 and the list of presented information displayed on the mixture injection support screen P44 in step S21 have the same content. Meanwhile, in another embodiment, the list of presented information displayed on the mixture injection support screen P22 and the list of presented information displayed on the mixture injection support screen P44 may be different. For example, the presentation information master D1 may be set to display a list of presented information corresponding to a combination of a drug type and a work process at either the start or end of the mixture injection work. Then, in step S13, the control unit 10 displays, on the mixture injection support screen P22, a list of presented information whose display timing is set to the start of the mixture injection work, and, in step S21, displays, on the mixture injection support screen P44, a list of presented information whose display timing is set to the end of the mixture injection work. In another embodiment, either or both of the display of the list of presented information in step S13 and the display of the list of presented information in the display area A442 in step S21 may be omitted. Furthermore, the control unit 10 may be able to set whether or not to display the list of the presentation information in step S13 and whether or not to display the list of the presentation information in step S21 in response to a user operation.

[0103] As described above, in the mixed injection assistance system 1, presentation information that is pre-registered in association with a combination of a drug type and a work process is displayed at a preset timing. In particular, the presentation information is displayed at the start of the work process corresponding to the presentation information. This allows the mixed injection worker to grasp the presentation information that should be confirmed for the work process at the start of the work process, and enables the mixed injection work to be performed appropriately. Furthermore, in the mixed injection assistance system 1, a list of the presentation information is displayed at the start and end of the mixed injection work. This allows the mixed injection worker to grasp the list of presentation information that should be confirmed for the mixed injection work at the start or end of the mixed injection work, and enables the mixed injection work to be performed appropriately.

[0104] Furthermore, when the mixed injection support process in beginner mode is completed, the control unit 10 may execute a change process to change whether or not to display the presentation conditions presented in the mixed injection support process. The control unit 10 can change whether or not to execute the change process in response to a user operation in initial settings, etc. The user operation in the change process may be performed by the mixed injection worker who is logged in to the mixed injection support process, or may be performed by another user who has a higher level of proficiency (skill level) than the mixed injection worker.

[0105] Specifically, in the change process, the control unit 10 displays on the operation display unit 12 a mixed injection support screen P61 (see FIG. 43) for changing whether or not to display the presentation conditions. As shown in FIG. 43, a display area A61 of the mixed injection support screen P61 displays a list of the presentation information presented in the mixed injection support process, and also displays an operation key K62 for switching between displaying and not displaying each piece of presentation information. The control unit 10 sequentially selects the presentation information in response to operation of the operation key K22, and when the operation key K21 is operated, switches between checking and unchecking the operation key K62 corresponding to the selected presentation information. Furthermore, when the operation key K62 is operated on the operation display unit 12, the control unit 10 also switches between checking and unchecking the operation key K62. Thereafter, when the operation key K23 is operated, the control unit 10 changes the display / uncheck setting in the presentation information master D1 to "off" for the presentation information that is checked in the operation key K62 on the mixed injection support screen P61. As a result, the presented information that has been checked on the mixed injection support screen P61 will not be displayed the next time the mixed injection support process is executed. Note that the mixed injection support screen P61 may allow an operation to change the message of the presented information.

[0106] [Mixed injection support processing: Expert mode] Next, with reference to Fig. 30, a description will be given of the mixed injection support process executed by the control unit 10 when the operation mode of the mixed injection support system 1 is the expert mode. For example, the mixed injection support process is executed by the control unit 10 when a mixed injection worker logs into the mixed injection support system 1 by inputting an ID, password, etc. using the operation display unit 12 and selects the expert mode as the operation mode. Below, an example of a mixed injection support screen P2 displayed on the operation display unit 12 during the mixed injection support process will be described with reference to Figs. 31 to 37. For ease of explanation, as shown in Figs. 31 to 37, the various mixed injection support screens P2 displayed in sequence during the mixed injection support process will be denoted by different reference numerals.

[0107] <Steps S30 to S31> In steps S30 to S31, the control unit 10 executes the same processes as steps S10 to S11, selecting the target preparation data and setting the details of the mixed injection work based on the target preparation data. Even when the operation mode of the mixed injection support system 1 is the expert mode, the mixed injection work is executed in the same manner as in the beginner mode. Specifically, in this embodiment, even in the expert mode, the mixed injection worker executes the mixed injection work shown in FIG. 8. However, unlike the mixed injection support process in the beginner mode, the mixed injection support process in the expert mode does not provide guidance on the order of execution of each work step in the mixed injection work. Therefore, a mixed injection worker with a relatively high level of proficiency (skill level) can refer to the details of the mixed injection work displayed on the mixed injection support screen P51 described below and efficiently execute the mixed injection work based on his or her own experience, etc.

[0108] <Step S32> In step S32, the control unit 10 displays the details of the mixed injection work on the mixed injection support screen P51 (see FIG. 31) of the operation display unit 12. As shown in FIG. 31, the mixed injection support screen P51 displays a display area A51 in which the details of the mixed injection work are displayed, and a display area A52 in which the details of the resultant product to be dispensed as a result of the mixed injection work are displayed. For example, in the example shown in FIG. 31, the display area A511 of the display area A51 shows the preparation details of the drug "5-FU injection 250 mg" as a single dose of "750 mg" and a preparation volume of "15 ml." Furthermore, the display area A512 of the display area A51 shows the preparation details of the drug "saline 500 mL" as a single dose of "1 bag," a discard volume of "15 ml," and a preparation volume of "485 ml."

[0109] Furthermore, when the operation key K23 or the third foot switch 163 is operated while "Prescription Contents" is displayed on the operation key K23 of the mixed injection support screen P51 as shown in FIG. 31, the control unit 10 displays the contents of the target preparation data on the operation display unit 12. This allows the mixed injection operator to check the contents of the target preparation data at any time. Note that, when all information is not displayed simultaneously on the mixed injection support screen P51, the control unit 10 slides the display contents of the mixed injection support screen P51 in response to a user operation.

[0110] <Step S33> In step S33, the control unit 10 determines whether the authentication process for the type of medicine used in the mixed injection work based on the target preparation data has been executed. Specifically, if code information corresponding to the type of medicine is read by the reading unit 13, the control unit 10 determines that the authentication process for the type of medicine has been executed. For example, if three bottles of the medicine "5-FU injection 250 mg" are used in the mixed injection work based on the target preparation data, the control unit 10 determines that the authentication process for the medicine has been completed if code information corresponding to the medicine "5-FU injection 250 mg" is read three times by the reading unit 13 in step S33, and the process proceeds to step S34.

[0111] If there are multiple medicine containers (medicine bottles, medicine boxes, bags, etc.) to be authenticated in the authentication process, the control unit 10 reads the code information, and if the number of times the code information has been read has not reached the number of those containers, displays in an identifiable manner, such as by the display color of the display area A513, that the authentication process is being carried out for that type of medicine, as shown in Fig. 32. After that, when the number of times the code information has been read reaches the number of those containers, the control unit 10 displays in an identifiable manner, such as by the display color of the display area A513, that the authentication process has been completed for that type of medicine, as shown in Fig. 33.

[0112] <Step S34> In step S34, the control unit 10 stores the result of the authentication step executed in step S33 as history information in the storage unit 11 in association with the target preparation data, and then proceeds to step S35.

[0113] <Step S35> In step S35, the control unit 10 determines whether or not the photographing step of photographing an image by the photographing unit 15 has been executed. Specifically, the control unit 10 displays the image photographed by the photographing unit 15 on the mixed injection support screen P52 (see FIG. 34). As a result, the mixed injection operator photographs an image of the mounting unit 141 of the weighing unit 14 and the syringe placed on the mounting unit 141 by the photographing unit 15, by operating the operation key K23 or the third foot switch 163 while referring to the mixed injection support screen P52. Then, once the image has been photographed, the control unit 10 returns the display screen of the operation display unit 12 to the mixed injection support screen P51.

[0114] <Step S36> In step S36, the control unit 10 stores the captured image captured in step S35 as history information in the storage unit 11 in association with the target preparation data, and proceeds to step S37. For example, when the control unit 10 completes the image capture for "5-FU 250 mg," it displays the captured image corresponding to "5-FU 250 mg" on the mixed injection support screen P51 as shown in FIG. 35. Similarly, when the control unit 10 completes the image capture for "500 mL saline," it displays the captured image corresponding to "500 mL saline" on the mixed injection support screen P51 as shown in FIG. 36. Furthermore, similar to the beginner mode, after the mixed injection operation is completed, the control unit 10 may photograph the infusion bag or other product resulting from the mixed injection operation, and store the photographed image as history information corresponding to the target preparation data. The control unit 10 may be able to preset whether or not to photograph the product in response to a user operation.

[0115] <Step S37> In step S37, the control unit 10 determines whether the mixed injection work based on the target preparation data has been completed. If the mixed injection work has been completed (S37: Yes), the control unit 10 proceeds to step S38, and if the mixed injection work has not been completed (S37: No), the control unit 10 returns to step S33. As a result, the control unit 10 continues to execute the processes of steps S33 to S36 in the same manner until the mixed injection work is completed.

[0116] <Step S38> In step S38, the control unit 10 displays a mixed injection support screen P53 (see FIG. 37) on the operation display unit 12, which displays the results of the mixed injection work. Specifically, the mixed injection support screen P53 displays, as results of the mixed injection work, whether or not the photographing step was performed, whether or not the authentication step was performed, and the measurement results in the measurement step, which correspond to each type of medicine. The mixed injection support screen P53 also displays information about the results of the mixed injection work, such as the volume of the resultant product and whether or not an image of the resultant product was taken.

[0117] As described above, in the beginner mode, the presented information is presented at a preset timing, but in the expert mode, the presented information is not presented. In the mixed injection assistance system 1, the operation mode can be switched between the beginner mode and the expert mode, and the display content in the mixed injection assistance process can be switched depending on the proficiency level of the mixed injection worker. This allows the mixed injection worker to efficiently and appropriately perform mixed injection work using an operation mode that corresponds to their own proficiency level.

[0118] In the beginner mode, the mixing support screen P2 corresponding to each work step included in the mixing operation is displayed in sequence, and the work step information for each work step is displayed in stages on each mixing support screen P2. This allows a mixing operator with a relatively low level of proficiency (skill level) to properly perform the mixing operation by sequentially referring to the work step information. On the other hand, in the expert mode, the work step information and the presentation information corresponding to each work step included in the mixing operation are not displayed. Instead, the mixing support screen P2 displays a list of preparation details, such as the types and amounts of medicines required for the mixing operation (see FIG. 31). The mixing support screen P2 does not transition to correspond to each work step except when the mixing support screen P52, which displays a captured image, is displayed. This allows a mixing operator with a relatively high level of proficiency (skill level) to efficiently perform the mixing operation by referring to the preparation details.

[0119] [Other features] In the mixed injection assistance system 1, the control unit 10 may have a history display function that displays historical information of mixed injection work stored in the storage unit 11 in association with the preparation data. Specifically, for example, in the expert mode, when a predetermined user operation is performed to refer to the historical information, the control unit 10 causes the operation display unit 12 to display a list of the preparation data for which the mixed injection work has been completed. The control unit 10 then causes the operation display unit 12 to display the historical information for the mixed injection work performed based on the preparation data selected by the user operation. The control unit 10 then displays a list of the presented information displayed in the mixed injection work corresponding to the historical information to be displayed, similar to the mixed injection assistance screen P61 shown in FIG. 43. The control unit 10 can change the display status of each piece of presented information or the content of the presented information in response to a user operation on the operation display unit 12. If the display status of each piece of presented information or the content of the presented information is changed, the control unit 10 reflects the changes in the presented information master D1 stored in the storage unit 11. This allows the user to easily change whether or not to display the presented information, or the content of the presented information, using the operation display unit 12 of the mixed injection support system 1 at the time of referring to the historical information.

[0120] Furthermore, in the mixed injection assistance system 1, the switching processing unit 104 of the control unit 10 may be capable of switching the operation mode of the mixed injection assistance system 1 not only between the beginner mode and the expert mode but also between other operation modes, such as a normal mode and a simple mode. For example, in the beginner mode, the presented information is presented at a preset timing as described above. On the other hand, in the expert mode, the normal mode, and the simple mode, the presented information is not presented. Furthermore, in the expert mode, the work process information for the weighing process is not presented, and in the simple mode, the work process information for the weighing process is presented. Furthermore, in the normal mode, detailed information such as the size of the syringe used in the mixed injection operation is presented, and the work process information for the weighing process is presented as in the simple mode. In addition, the mixed injection assistance system 1 may have a no-weight mode as one of the operation modes. The no-weight mode is an operation mode in which the authentication process (S33 to S34) and the photographing process (S35 to S36) are executed, similar to the mixed injection assistance process in the expert mode. The expert mode and the weightless mode differ in that the order of drug authentication in the authentication process is not predetermined in the expert mode, whereas the order of drug authentication in the weightless mode is predetermined in the authentication process, but are otherwise the same. For example, the beginner mode, normal mode, simple mode, weightless mode, and expert mode listed here prioritize guiding the user through the work process in the mixed injection operation in this order. That is, the beginner mode is the operating mode with the highest guidance priority, and the expert mode is the operating mode with the least amount of guidance information. The names of the various operating modes described here are merely examples; for example, the beginner mode may be referred to as the full navigation mode and the expert mode as the skip mode.

[0121] [Preparation procedure registration function] As described above, in the mixed injection support system 1, in various operation modes such as the beginner mode and the expert mode, the work process information indicating the contents of various work processes to be performed as mixed injection work based on the preparation data is generated and presented based on the preparation data and the preparation work master. The setting terminal 2 has a preparation procedure registration function that registers the contents of the preparation work master used to generate the work process information in response to a user operation.

[0122] The preparation work master is stored in the storage unit 11 of the mixed injection support system 1 and the storage unit of the setting processing unit 21 of the setting terminal 2. The preparation work master can register a plurality of preparation procedure data, each of which includes detailed information indicating the content of one or more preparation procedures, which are work steps to be performed as the mixed injection work, and condition information indicating the conditions for using the preparation procedure data in generating the work step information. The preparation procedure data also includes preparation procedure drug information, including information on various drugs referenced when generating the work step information based on the preparation procedure data. The preparation procedure drug information includes information (e.g., drug code, drug name), drug type, infusion type, amount of water that can be mixed, dissolution amount, specific gravity, syringe, and concentration (see FIG. 47 ) for the drugs used in the work step information generated based on the preparation procedure data. The preparation procedure drug information stored in the storage unit 11 can also be referenced by the setting processing unit 21 of the setting terminal 2. The preparation procedure drug information may also be stored in the storage unit of the setting processing unit 21. The contents of the preparation procedure drug information may be included in the drug master. Furthermore, when the setting processing unit 21 sets the preparation procedure drug information, it may be possible to reflect part of the information in the drug master in the preparation procedure drug information. Furthermore, in the drug master, a preparation procedure number or the like that can identify the preparation procedure data that is applied when each drug is used may be registered for each drug. Furthermore, the creation date when the preparation procedure data was registered (newly registered or edited) and the like are also registered for each of the preparation procedure data.

[0123] Then, when generating the work process information in step S11, the control unit 10 identifies the preparation procedure data to be used for generating the work process information based on the preparation data, based on the preparation data and the condition information. For example, the control unit 10 may identify the preparation procedure data based on the drug type of the drug registered in the preparation procedure drug information in association with the drug identification information included in the preparation data, or may identify the preparation procedure data based on a combination of the drug type of the drug and the drug identification information. Furthermore, when the preparation procedure number is registered in association with the drug included in the preparation data in the drug master, the control unit 10 may identify the preparation procedure data to be used for generating the work process information based on the preparation procedure number.

[0124] Once the preparation procedure data is identified, the control unit 10 then generates the work process information based on the identified preparation procedure data and the preparation data. When generating the work process information based on the preparation procedure data, the control unit 10 expands the various preparation procedures included in the preparation procedure data into an authentication step, a tare step, a weighing step, a photographing step, a mixed injection step, etc., based on preset specifications. For example, if a preparation procedure for withdrawing infusion fluid is set in the preparation procedure data, the control unit 10 expands the contents of the preparation procedure for withdrawing infusion fluid into an authentication step, a tare step, a weighing step, and a photographing step for the infusion fluid shown in Figures 12 to 16.

[0125] Specifically, the preparation procedure registration function is realized by the setting processing unit 21 of the setting terminal 2 executing a preparation procedure registration process. For example, the setting processing unit 21 executes the preparation procedure registration process when a predetermined preparation procedure registration start operation is performed by a user on the operation display unit 22. Furthermore, the setting processing unit 21 may execute the preparation procedure registration process when it is not possible to generate the work process information for preparation data (prescription data) to be processed in the mixed injection support system 1 based on the preparation data and the preparation work master. When the preparation procedure registration process is executed when the preparation work master corresponding to the preparation data cannot be identified, some preset information, such as drug identification information or drug type, among the drug information included in the preparation data may be automatically reflected in the condition information of the preparation procedure data.

[0126] An example of the preparation procedure registration process will be described below with reference to FIG. 44. In another embodiment, the preparation procedure registration process may be executed by the control unit 10 of the mixed injection support system 1 or the host system 3. For example, in step S11, if the work process information cannot be generated based on the preparation data (prescription data) to be processed and the preparation work master, the preparation procedure registration process may be executed by the control unit 10. Furthermore, the control unit 10 of the mixed injection support system 1 or the setting processing unit 21 of the setting terminal 2 may limit users who can edit the preparation work master to specific users set in advance. For example, in a configuration in which the operation mode of the mixed injection support system 1 is switched in association with the currently logged-in mixed injection worker, the mixed injection worker associated with the expert mode may be set as the specific user.

[0127] <Step S41> In step S41, the setting processing unit 21 displays a search screen for searching for the preparation procedure data registered in the preparation work master on the operation display unit 22. On the search screen, it is possible to input information on condition items such as the preparation procedure name, creation date, drug, infusion, drug combination, regimen, procedure, route, comment, drug dosage, total amount, and patient weight as search conditions. The search screen also displays a search start key for starting a search for the preparation procedure data based on the search conditions, a new registration key for starting new registration of the preparation procedure data, and the like.

[0128] <Step S42> In step S42, the setting processing unit 21 determines whether a new registration start operation for the preparation procedure data has been performed. For example, the new registration start operation is an operation of the new registration key. If it is determined that the new registration start operation has been performed (S42: Yes), the process proceeds to step S47. If the new registration start operation has not been performed (S42: No), the process proceeds to step S43.

[0129] <Step S43> In step S43, the setting processing unit 21 determines whether a search start operation for the preparation procedure data has been performed. For example, the search start operation is the operation of the search start key. If it is determined that the search start operation has been performed (A43: Yes), the process proceeds to step S44. If the search start operation has not been performed (A43: No), the process returns to step S42.

[0130] <Step S44> In step S44, the setting processing unit 21 searches the preparation work master for the preparation procedure data that matches the search conditions based on the condition information of the preparation procedure data. For example, if the content of a preparation procedure name is input as the search condition, the preparation procedure data for which the content of the preparation procedure name is registered in the condition information is extracted. Also, if the drug code or drug name of a drug is input as the search condition, the preparation procedure data for which the drug is registered in the condition information is extracted.

[0131] <Step S45> In step S45, the setting processing unit 21 displays a list of one or more pieces of preparation procedure data extracted in step S44 on the operation display unit 22. In the list display of the preparation procedure data, the preparation procedure name registered in the condition information of each piece of preparation procedure data, the creation date of the preparation procedure data, etc. are displayed.

[0132] <Step S46> In step S46, the setting processing unit 21 determines whether or not preparation procedure data to be edited has been selected from the preparation procedure data displayed in step S45. If it is determined that the preparation procedure data has been selected (S46: Yes), the process proceeds to step S47, and the process waits in step S46 until the preparation procedure data is selected (S46: No). Note that while the process waits in step S46, the setting processing unit 21 can also return the process to step S41 in response to a predetermined user operation.

[0133] <Step S47> In step S47, the setting processing unit 21 displays a registration screen P70 for inputting the details of the preparation procedure data on the operation display unit 22. Fig. 45 is a diagram showing an example of the registration screen P70.

[0134] 45, the registration screen P70 displays operation keys K71 to K74, a condition registration screen P71, a details registration screen P72, and the like. The registration screen P70 may fit within one screen that is simultaneously displayed on the display unit of the operation and display unit 22, and the display location of the registration screen P70 on the operation and display unit 22 may be changed in response to a swipe operation or a scroll operation. Furthermore, the registration screen P70 includes the condition registration screen P71 and the details registration screen P72, but the condition registration screen P71 and the details registration screen P72 may be displayed on the operation and display unit 22 as independent display screens at different times.

[0135] The setting processing unit 21 accepts the operation of the operation key K71 as an operation for registering the content entered on the registration screen P70 as the preparation procedure data in the preparation work master. The setting processing unit 21 also accepts the operation of the operation key K72 as an operation for simulating the content of the mixed injection work set in step S11 (FIG. 7: mixed injection support process) when temporary preparation data (prescription data) to be used for the simulation is entered in a state where the content entered on the registration screen P70 has been temporarily registered as the preparation procedure data. The setting processing unit 21 also accepts the operation of the operation key K73 as an operation for deleting the preparation procedure data displayed on the registration screen P70 from the preparation work master. The setting processing unit 21 also accepts the operation of the operation key K74 as an operation for terminating the process without saving the content entered on the registration screen P70.

[0136] The condition registration screen P71 displays an input field for inputting the contents of one or more condition items to be registered in the condition information as conditions for using the preparation procedure data to be registered in step S11 (FIG. 7: mixed injection support processing). Here, in the case of new registration of the preparation procedure data (S42: Yes), the setting processing unit 21 displays the condition registration screen P71 in an empty state, and in the case of editing of the preparation procedure data (S46: Yes), the setting processing unit 21 displays the condition registration screen P71 in a state in which the contents of the condition items registered in the selected preparation procedure data have been entered.

[0137] Then, in response to the user's operation of the operation display unit 22, the setting processing unit 21 inputs information such as numbers or letters into an input field on the condition registration screen P71, and selects any one or more options from a plurality of options. Specifically, the condition registration screen P71 displays, as the condition items, the preparation procedure name, drug, infusion, drug combination, regimen, procedure, route, comment, drug dose, total amount, patient weight, and the like. The condition items are the same as the items input as search conditions on the search screen. In addition, the condition information also stores a preparation procedure number that can identify the preparation procedure data, and the preparation procedure number is also included in the detailed information.

[0138] For example, among the condition items, the drug, infusion, regimen, procedure, and route may be entered using preset alphanumeric codes or any text. When a code is entered in the left input field for the drug, infusion, regimen, procedure, and route, the setting processing unit 21 displays preset information corresponding to the code in the right input field. Regarding drug combinations, a user can select any of preset options, such as liquid medicine, powder (with solvent), powder (without solvent), infusion, and over-the-counter medicine, and multiple options can also be selected. Note that "powder (with solvent)" indicates that the powdered drug contains a solvent (attached solvent), and "powder (without solvent)" indicates that the powdered drug does not contain a solvent (attached solvent). Regarding comments, either partial or complete match can be selected as a match determination condition, and text information for the match determination can be entered. Furthermore, for the drug dosage, total amount, and patient weight, a lower or upper limit can be entered.

[0139] The detail registration screen P72 displays a display area A721 that accepts a registration operation for the content and order of one or more preparation procedures included in the detailed information of the preparation procedure data to be registered, and a display area A722 that displays the content of one or more preparation procedures included in the detailed information of the preparation procedure data. Here, the setting processing unit 21 displays the display area A722 in an empty state when the preparation procedure data is newly registered (S42: Yes), and displays the display area A722 in a state where the content of the detailed information registered in the selected preparation procedure data is entered when the preparation procedure data is edited (S46: Yes).

[0140] The preparation procedures include, for example, "drug extraction," "infusion extraction," and "mixing." The display area A721 displays operation keys K721-728 corresponding to the respective contents of the registration operation of the preparation procedures. The display area A722 displays a display area A723 corresponding to each of the preparation procedures. Each of the display areas A723 corresponding to each of the preparation procedures corresponds to a step of the preparation procedure displayed on the mixed injection support screen P23 of FIG. 11, for example. The setting processing unit 21 accepts input of the contents and order of the preparation procedures to be registered in the detailed information of the preparation procedure data in response to user operations on the display area A721 and the display area A722. Specifically, the vertical display order of the display areas A723 in the display area A722 indicates the order of the preparation procedures corresponding to the display area A723, with the top row being the first preparation procedure.

[0141] The detailed information of the preparation procedure data includes various information such as the preparation procedure number, procedure creation type, preparation group, preparation number, procedure number, and procedure serial number of the preparation procedure data. The preparation procedure number is information that can identify the preparation procedure data and is also included in the condition information. The procedure creation type indicates which operation mode the work process information created using the preparation procedure data corresponds to, and is set to one of normal procedure, simple procedure, expert mode, beginner mode, no-weight mode, etc. The preparation group is identification information that is assigned from top to bottom to each preparation procedure corresponding to each display area A723 displayed in the display area A722 (see Figure 45), which will be described later. The preparation number is a serial number that is assigned across the preparation procedure groups for each operation from a source drug to a destination drug. For example, in the top display area A723 (preparation group) in the display area A722 of FIG. 45, the three pieces of operation information, "dissolving solution," "withdrawal," and "injection and dissolution," are assigned a single consecutive preparation number (e.g., "1") within the entire preparation group, and the two pieces of operation information, "injection and dissolution" and "withdrawal after dissolution," are assigned a single consecutive preparation number (e.g., "2") within the entire preparation group. In the second display area A723 (preparation group) from the top in the display area A722 of FIG. 45, the three pieces of operation information, "dissolving solution," "withdrawal all together," and "injection and dissolution," are assigned a single consecutive preparation number (e.g., "3") within the entire preparation group, and the two pieces of operation information, "injection and dissolution" and "withdrawal after dissolution," are assigned a single consecutive preparation number (e.g., "4") within the entire preparation group. The procedure numbers are consecutive numbers assigned to each operation from a source drug to a destination drug within the same preparation group. For example, in the top display area A723 (preparation group) in display area A722 of Figure 45, the three pieces of operation information, "dissolving liquid," "withdrawal," and "injection and dissolution," are assigned a single consecutive procedure number within the preparation group (e.g., "1"), and the two pieces of operation information, "injection and dissolution" and "withdrawal after dissolution," are assigned a single consecutive procedure number within the preparation group (e.g., "2").

[0142] The detailed information also includes various information indicating the details of the preparation procedure registered in the preparation procedure data, such as a drug code, a preparation number group preparation category, a preparation type, a preparation operation category, a withdrawal amount, a final container selection category, a preparation unit, a fractional procedure flag, a standard procedure flag, a combined procedure flag, and a discard procedure flag. The preparation number group preparation category is set to one of liquid, powder, infusion, mixed injection, etc. The preparation type is set to one of liquid, powder (with solvent), powder (without solvent), infusion, syringe, bag, infuser pump, comment, etc. The preparation operation category is set to one of withdrawal, injection, discard after withdrawal, other (comment), mixed injection completed, drug solution after withdrawal, withdrawal after injection, mixed injection, drug solution after withdrawal, etc. The final container selection category is set to one of no specification, infusion, syringe, bag, infuser pump, etc., and the preparation unit is set to one of single substance, drug, standard, etc. The fractional procedure flag is set to either the whole amount, fractional amount, etc. regarding the presence or absence of fractional amounts. The standard procedure flag is set to either small standard volume → large, large standard volume → small, etc. regarding the standard volume. The consolidation procedure flag is set to either no consolidation designation, per drug, per standard, etc. The discard procedure flag is set to either no discard designation (sampling), the amount exceeding the amount of water that can be mixed, the amount exceeding the designated dose, the amount equivalent to the anticancer drug, the remaining amount, etc.

[0143] The operation keys K721 to K725 are used to accept a selection operation of the type of preparation procedure. More specifically, the operation key K721 corresponds to "extraction of liquid medicine," the operation key K722 corresponds to "extraction of powder medicine (with solvent)," the operation key K723 corresponds to "extraction of powder medicine (without solvent)," the operation key K724 corresponds to "extraction of infusion," and the operation key K725 corresponds to "mixing." Then, in response to the operation of the operation keys K721 to K725, the setting processing unit 21 adds to the display area A722 a display area A723 that indicates a preparation procedure of a preset type associated with the operated operation key. For example, the setting processing unit 21 adds a display area A723 showing a pre-set preparation procedure associated with the type of "extraction of liquid medicine" to the display area A722 in response to operation of the operation key K721, and adds a display area A723 showing a pre-set preparation procedure associated with the type of "extraction of powder medicine (no dissolving liquid)" to the display area A722 in response to operation of the operation key K722.

[0144] Furthermore, operation keys K726 and K727 are used to accept operations to rearrange the order of each display area A723 displayed in display area A722, i.e., the execution order of the preparation procedures. Specifically, when operation key K726 is operated while any display area A723 is selected in display area A722, setting processing unit 21 moves the selected display area A723 upward by one position. Furthermore, when operation key K727 is operated while any display area A723 is selected in display area A722, setting processing unit 21 moves the selected display area A723 downward by one position.

[0145] Furthermore, the operation key K728 is used to accept an operation to delete the preparation procedure corresponding to the display area A723 displayed in the display area A722. Specifically, when the operation key K726 is operated while any display area A723 is selected in the display area A722, the setting processing unit 21 deletes the preparation procedure corresponding to the selected display area A723.

[0146] Furthermore, the setting processing unit 21 edits the input content of the detailed information in response to user operations on operation areas A724 to A730 in the display area A723. Specifically, when operation area A724 is operated, the setting processing unit 21 sequentially changes the preparation unit set in the operation area A724 to single substance, drug, standard, etc. Furthermore, when operation area A725 is operated, the setting processing unit 21 sequentially changes the drug preparation order set in the operation area A725 from small standard to large standard, large standard to small standard, etc. Furthermore, when operation area A726 is operated, the setting processing unit 21 sequentially changes the grouping method set in the operation area A726 to not group, by drug, by standard, etc. Furthermore, when operation area A727 is operated, the setting processing unit 21 displays a screen for searching for and selecting the drug name set in the operation area A727, and inputs the selected drug name. Furthermore, when operation area A728 is operated, the setting processing unit 21 sequentially changes the solution sampling consolidation set in operation area A728 to not consolidate, drug amount, standard amount, etc. Furthermore, when operation area A729 is operated, the setting processing unit 21 sequentially changes the sampling consolidation set in operation area A729 to not consolidate, consolidate, etc. Furthermore, when operation area A730 is operated, the setting processing unit 21 sequentially changes the infusion disposal method set in operation area A730 to not consolidate, amount exceeding the allowable mixed infusion amount, remaining amount, etc. Furthermore, when the type of preparation procedure is mixing, the setting processing unit 21 sequentially changes the final container to not specified, infusion bag, syringe, bag, infuser pump, etc. in accordance with operation of an area (not shown) displaying the final container.

[0147] Note that the various input methods in the display area A723 are not limited to a method of sequentially switching input contents in response to operation of each operation area, but may also be a method in which selection candidates are displayed on a pop-up screen or pull-down screen in response to operation of each operation area, and arbitrary information is input from the selection candidates. In another embodiment, the operation area A726 may be assigned a "fraction preparation order," and the setting processing unit 21 may sequentially change the setting content of the "fraction preparation order" to first, last, fraction, full amount, etc. in response to operation of the operation area A726. The display positions of the various operation keys such as the operation keys K721 to K728 and the various operation areas such as the operation areas A724 to A728 shown in FIG. 45 are merely examples, and these display positions may be any predetermined positions.

[0148] 46(A), if a drug name including its specification has already been entered in operation area A727, when operation area A727 is operated, the setting processing unit 21 causes a drug information screen P80 to be displayed as a pop-up on the operation display unit 22, as shown in FIG. 47. The drug information screen P80 displays information registered in the drug preparation procedure information for the drug corresponding to the drug name, as shown in FIG. 47. The setting processing unit 21 can change various information, such as the dissolution amount and concentration of the drug, included in the drug preparation procedure information for the drug displayed on the drug information screen P80, in response to a user operation on the drug information screen P80. The setting processing unit 21 then reflects the changes made on the drug information screen P80 in the drug preparation procedure information and closes the drug information screen P80.

[0149] On the other hand, as shown in FIG. 46(B), if a drug name not containing a standard has already been entered in the operation area A727, when the operation area A727 is operated, the setting processing unit 21 searches for drug names containing a standard based on the drug name not containing the standard as selection candidates, as shown in FIG. 46(C), and causes the operation display unit 22 to pop up a selection screen P81 for selecting an arbitrary drug name from the selection candidates. Thereafter, when a drug name is selected on the selection screen P81, the setting processing unit 21 pops up a drug information screen P80 (see FIG. 47) on the operation display unit 22, displaying information about the drug corresponding to the selected drug name. Furthermore, the setting processing unit 21 can change various information, such as the dissolution amount and concentration of the drug, included in the preparation procedure drug information for the drug displayed on the drug information screen P80 in response to a user operation on the drug information screen P80. The setting processing unit 21 then reflects the changes made on the drug information screen P80 in the preparation procedure drug information and closes the drug information screen P80. Thereafter, when a drug name is selected on the selection screen P81 and an operation to confirm the drug name is performed, the drug name is input into the operation area A727.

[0150] <Step S48> In step S48, the setting processing unit 21 determines whether or not a registration operation has been performed to register the contents of the preparation procedure data displayed on the setting screen P70. For example, the setting processing unit 21 determines that a registration operation has been performed when the operation key K71 has been operated. If it is determined that a registration operation has been performed (S48: Yes), the process proceeds to step S49, and if a registration operation has not been performed (S48: No), the process returns to step S47.

[0151] <Step S49> In step S49, the setting processing unit 21 registers the contents of the preparation procedure data displayed on the setting screen P70 in the preparation work master. Specifically, the information entered on the condition registration screen P71 of the setting screen P70 is registered as the registration information of the preparation procedure data, and the information entered on the detail registration screen P72 is registered as the detail information of the preparation procedure data. Here, if the preparation procedure data is newly registered (S42: Yes), the contents of the preparation procedure data are added to the preparation work master, and if the preparation procedure data is edited (S46: Yes), the contents of the preparation procedure data in the preparation work master are updated.

[0152] Furthermore, in step S49, the setting processing unit 21 also stores the preparation work master reflecting the registration contents in the preparation procedure registration process in the storage unit 11 of the mixed injection support system 1, thereby updating the preparation work master stored in the storage unit 11. Note that the setting processing unit 21 may update the preparation work master stored in the storage unit 11 by storing only the preparation procedure data to be registered in the preparation procedure registration process in the storage unit 11 of the mixed injection support system 1. That is, as long as the preparation work master in the setting terminal 2 and the preparation work master in the mixed injection support system 1 are synchronized, the synchronization method is not limited to this. For example, the control unit 10 may read the latest preparation work master from the setting terminal 2 at a preset timing and store it in the storage unit 11, thereby updating the preparation work master stored in the storage unit 11. Furthermore, the preparation work master may be stored in the higher-level system 3, and the preparation work master may be updated according to the results of the preparation procedure registration process.

[0153] As a result, in the mixed injection support system 1, when the control unit 10 sets the work process information based on the preparation work master and the preparation data in step S31 of the mixed injection support process, it is possible to use the preparation procedure data that the user has voluntarily registered through the preparation procedure registration process.

[0154] As described above, in the setting terminal 2, the user can freely manage the preparation work master that indicates the content and order of the preparation procedures to be performed in the mixed injection work, and in the mixed injection support system 1, the work process information is generated and presented based on the preparation work master managed by the setting terminal 21.

[0155] [Example of registration operation] Here, a specific example of a user operation when registering the preparation procedure data in the preparation work master using the registration screen P70 will be described along with screen transitions. Figure 48 is a diagram showing another example of the registration screen P70 (see Figure 45), and the following describes the operation of registering the preparation procedure data using the registration screen P70 shown in Figure 48. The registration screen P70 displayed in Figure 48 is a screen that is initially displayed by the setting processing unit 21 when an operation to start new registration of the preparation procedure data is performed, and the contents of the condition information and the detailed information are blank (unentered) on this registration screen P70.

[0156] Description of the parts of the registration screen P70 in Fig. 48 that are common to the registration screen P70 in Fig. 45 will be omitted. For example, the display positions of the condition items set in the condition registration screen P71 are different on the registration screens P70 in Fig. 48 and Fig. 45, but the "Drug Name," "Soluble Solution," "Drug Type," and "Drug Dosage" on the condition registration screen P71 of the registration screen P70 in Fig. 48 correspond to the "Drug," "Infusion," "Drug Combination," and "Dose" on the condition registration screen P71 of the registration screen P70 in Fig. 45, respectively, and the other items are the same. Furthermore, on the registration screen P70 in Fig. 48, one or more condition items are displayed in groups of basic, drug, details, and patient on the condition registration screen P71.

[0157] Furthermore, when condition information such as a drug type and a drug name is input on the condition registration screen P71 of the registration screen P70, the setting processing unit 21 changes the operation keys K721 to K725 that are displayed in the display area A721 of the detail registration screen P72 and that can be operated by the user, in accordance with the drug type and the drug name. Note that the operation key K725 is an operation key that corresponds to "mixing," as will be described later, and is an adjustment procedure that is essential for creating the preparation procedure data. Therefore, the setting processing unit 21 may always display the operation key K725 on the detail registration screen P72, as shown in FIG. 48, regardless of whether the condition information is input or not.

[0158] Here, we will first explain an example where a liquid medicine is selected as the medicine type, and then explain an example where a powder medicine is selected as the medicine type. Note that either the medicine type or the medicine name may be set as the condition item, and the setting processing unit 21 may register the adjustment procedure data corresponding to that item. Furthermore, at least the medicine type among the condition items may be set as a required input item.

[0159] [Chemical type: Liquid medicine] 49 shows an example of the display in the display area A721 when "5-FU injection" is entered as the drug name and "liquid drug" and "infusion" are entered as the drug type. In this display area A721, two operation keys K721 displaying "5-FU" and "liquid drug," an operation key K724 displaying "infusion," and an operation key K725 displaying "mixture" are displayed. That is, the setting processing unit 21 displays operation keys K721, K721, K724, and K725 out of the operation keys K721 to K725 that are displayed in the display area A721 of the detail registration screen P72 and operable by the user in accordance with the drug type and drug name on the condition registration screen P71 of the registration screen P70, and omits the display of operation keys K722 and K723. Furthermore, operation keys that cannot be operated by the user may be displayed by being grayed out, for example. The correspondence between the drug type and drug name and the operation keys K721 to K725 displayed in the display area A721 of the detailed registration screen P72 is stored in advance in the memory unit 11 of the mixed injection support system 1 or the memory unit of the setting processing unit 21 of the setting terminal 2, and the setting processing unit 21 selects and displays the operation keys K721 to K725 that can be operated by the user based on the correspondence.

[0160] Thereafter, when any of the operation keys K721 to K725 is operated, the setting processing unit 21 displays in the display area A722 a display area A723 corresponding to the preparation procedure corresponding to the operated operation key K721 to K725. For example, Fig. 50 shows a state in which the operation key K724 is operated and one display area A723 corresponding to the preparation procedure of infusion withdrawal is displayed in the display area A722. Here, when the display area A723 is operated, the setting processing unit 21 selects the operated display area A723 as the object to be edited, and displays editable items in the display area A723 in a manner that allows them to be distinguished from other uneditable items, for example, by using a preset display color such as yellow, a preset character size, or by underlining.

[0161] For example, in the example shown in FIG. 50 , an operation area A731 for setting an infusion withdrawal method and an operation area A732 for setting a designated amount are set as editable items in the display area A723 to be edited, and an operation key K731 for confirming the edit for the display area A723 is also displayed. As shown in the imaginary line area R1 in FIG. 50 , the setting processing unit 21 sequentially switches the text and illustration indicating the infusion withdrawal method to those corresponding to “discard,” “syringe,” and “infuser” each time the operation area A731 is operated. When the operation area A732 is operated, the setting processing unit 21 pops up an operation screen P724 for setting the designated amount, as shown in FIG. 50 . In response to a user operation on the operation screen P724, the setting processing unit 21 sets the designated amount to the ordered amount or to an arbitrary value input. Thereafter, when the input of the designated amount on the operation screen P724 is confirmed by a user operation, the setting processing unit 21 reflects the designated amount in the content of the preparation procedure data being edited and displays it in the operation area A732, as shown in Fig. 51. Furthermore, when the operation key K731 displayed in the display area A723 is operated, the setting processing unit 21 confirms the edited content in the display area A723 and releases the display area A723 from the editing target.

[0162] Furthermore, as shown in Fig. 52, for example, when the operation key K721 corresponding to "5-FU" is operated, the setting processing unit 21 adds a display area A723 for the preparation procedure of drug extraction corresponding to "5-FU" to the display area A722, and edits the content of the preparation procedure of drug extraction in accordance with the user's operation of the display area A723. Then, the user operates the operation keys K721 to K725 in the display area A722 as necessary to add the display area A723 corresponding to one or more preparation procedures to be registered as the preparation procedure data, and then operates the operation key K71 corresponding to the registration operation (step S48 in Fig. 44: Yes). As a result, the setting processing unit 21 registers the content entered on the registration screen P70 as the preparation procedure data (step S49 in Fig. 44).

[0163] [Chemical type: Powder] 53 shows an example of the display in the display area A721 when the drug name is "Gemcitabine Injection" and the drug types are "Powder (without dissolving solution)" and "Infusion." In the display area A721, an operation key K723 displaying "Gemcitabine Injection," an operation key K724 displaying "Infusion," and an operation key K725 displaying "Mixture" are displayed. That is, the setting processing unit 21 displays operation keys K721, K723, and K725 among the operation keys K721 to K725 that are displayed in the display area A721 of the detail registration screen P72 and operable by the user in accordance with the drug type and drug name on the condition registration screen P71 of the registration screen P70, and omits the display of the operation key K722. For example, FIG. 54 shows a state in which the operation key K723 is operated, and one display area A723 corresponding to the drug dissolution / extraction preparation procedure is displayed in the display area A722. In addition, the display area A723 corresponding to the preparation procedure for dissolving and extracting the drug displays two steps corresponding to one preparation procedure: the step of extracting the dissolving liquid and injecting it into a drug container to dissolve it, and the step of extracting the drug liquid from the drug container with a syringe after dissolution.

[0164] Here, when the display area A723 is operated, the setting processing unit 21 selects the operated display area A723 as the editing target and displays editable items in the display area A723 in a manner that makes them distinguishable from other uneditable items, for example, by using a preset display color such as yellow, a preset character size, or by underlining. For example, in the example shown in Fig. 54, an operation area A733 for setting a solvent is set as an editable item in the display area A723 to be edited. Then, as shown in the imaginary line area R2 in Fig. 54, the setting processing unit 21 sequentially switches the characters and illustration indicating the type of solvent to those corresponding to "solvent," "water for injection," and "saline" each time the operation area A733 is operated.

[0165] As described above, the setting processing unit 21 or the control unit 10 may execute the preparation procedure registration process when it is unable to generate the work process information based on the preparation data and the preparation work master. In this case, the setting processing unit 21 or the control unit 10 may determine whether it is possible to generate the work process information based on the preparation data and the preparation work master, for example, by determining whether the preparation procedure data in which the drug identification information (e.g., drug name) included in the preparation data and the drug type (liquid, powder (with solvent), powder (without solvent), infusion, etc.) are set as the condition items are stored in the preparation work master. The drug type is registered in the preparation procedure drug information (see FIG. 47) in association with the drug identification information. The setting processing unit 21 or the control unit 10 may also determine that it is possible to generate the work process information when the preparation procedure data in which at least the drug type (liquid, powder (with solvent), powder (without solvent), infusion, etc.) of the drug included in the preparation data is set as the condition item is stored in the preparation work master. Similarly, the setting processing unit 21 or the control unit 10 may determine that the work process information can be generated when the preparation procedure data in which at least the identification information of the drug (such as the drug name) included in the preparation data is set as the condition item is stored in the preparation work master. Alternatively, the setting processing unit 21 or the control unit 10 may determine whether the work process information can be generated based on whether the preparation procedure data in which the predetermined search target information is set as the condition item is stored in the preparation work master, regardless of whether the search target information is the identification information of the drug and the drug type of the drug, as long as the search target information is specified based on various information included in the preparation data. In this way, in the mixed injection support system 1, when the preparation procedure data required to generate the work process information based on the preparation data is not set in the preparation work master, for example, when the preparation data includes a new drug, the preparation procedure data can be set in response to a user operation.In particular, the preparation procedure data allows the detailed contents of each preparation procedure to be set in accordance with user operations, thereby realizing a mixed injection support system 1 that is highly versatile for users.

[0166] [Simulation function] As described above, the setting processing unit 21 has a function of simulating and displaying the generation of the work process information based on the preparation procedure data input on the registration screen P70 in response to the operation of the operation key K72 displayed on the registration screen P70. That is, while the preparation procedure data is being set using the registration screen P70, the setting processing unit 21 can simulate and display the results of the work process information generated by the control unit 11 based on the preparation procedure data and the preparation data. Furthermore, after the preparation procedure data is set using the registration screen P70, the setting processing unit 21 may be able to simulate and display the results of the work process information generated by the control unit 11 based on the preparation procedure data and the preparation data.

[0167] Specifically, when the operation key K72 is operated, the setting processing unit 21 displays a prescription selection screen (not shown) for selecting preparation data (prescription data) to be used for a simulation, and accepts a selection operation for selecting the preparation data displayed on the prescription selection screen as a request to start a simulation. When search conditions such as prescription classification, medical department, dispensing date, administration date, dispensing location, order number, and patient are set on the prescription selection screen, the setting processing unit 21 can search for and display preparation data based on the search conditions. When preparation data is selected on the prescription delivery screen, the setting processing unit 21 displays the contents of the preparation data, generates the work process information based on the preparation data and the preparation procedure data entered on the registration screen P70, and displays a simulation screen P90 on the operation display unit 22, where the work process information is displayed as a simulation result. For example, FIG. 55 shows an example of the display of the simulation screen P90.

[0168] 55, the simulation screen P90 first displays, as output information of the mixed injection work based on the preparation data, information on the dispensed infusion container, "500 mL of saline," information on the "dosage" (total amount) indicating the total amount to be administered (dosage, weight), information on the preparation amount (anticancer drug amount) indicating the preparation amount (dosage, weight) of the anticancer drug, etc. The simulation screen P90 also displays the contents of the work process information generated based on the preparation data and the preparation procedure data entered on the registration screen P70.

[0169] This allows the user to easily determine whether the content of the preparation procedure data edited on the registration screen P70 is appropriate. For example, by referring to the simulation screen P90, the user can confirm the amount of drug to be sampled in the mixed injection work based on the preparation data and the flow of each work step in the mixed injection work. After displaying the simulation screen P90, the setting processing unit 21 terminates the display of the simulation screen P90 in response to a user operation, redisplays the registration screen P70, and resumes editing of the preparation procedure data in response to the user operation. Therefore, the user can repeatedly edit and confirm the preparation procedure data using the registration screen P70 and the simulation screen P90 as necessary, and easily create appropriate preparation procedure data.
