Description

Mixed injection management device, mixed injection device, mixed injection management program

The present invention relates to a control technique for a co-infusion apparatus that executes co-infusion processing for injecting a drug such as an anticancer drug contained in a drug container into an infusion container.

There is known a co-infusion apparatus that performs a co-infusion process in which a drug such as an anticancer drug contained in a drug container such as an ampoule or a vial is sucked with a syringe and the drug is injected into an infusion bag containing the infusion solution. (For example, refer to Patent Document 1). In this type of co-infusion apparatus, co-infusion processing is performed in a safety cabinet set to a negative pressure in order to prevent exposure to chemicals such as anticancer agents. Note that a predetermined amount of medicine predetermined for each medicine is stored in one medicine container, and the user can use one or more medicine containers satisfying the amount of medicine to be dispensed indicated in the preparation data in the co-infusion apparatus. Load it.

JP 2012-250016 A

By the way, if the dispensing amount of the medicine shown in the preparation data is not an integral multiple of the predetermined amount of the medicine in the medicine container, the medicine remains in the medicine container after the co-infusion process. Accordingly, an object of the present invention is to provide a mixed injection management device, a mixed injection device, and a mixed injection management program capable of supporting efficient use of a medicine in a medicine container containing a predetermined amount of medicine.

The mixed injection management apparatus according to the present invention includes a determination unit and a display control unit. Whether the drug remains in the drug container used in the mixed injection process in which the drug indicated in the preparation data is injected from one or a plurality of drug containers containing the predetermined amount of the drug into the infusion container. Judge whether or not. The display control means uses, as a prescription drug, a medicine of the same type as the remaining medicine determined to remain in the medicine container in the past mixed injection processing by the determination means among the selection candidates of the preparation data to be subjected to the mixed injection processing. The prepared preparation data is preferentially displayed on the display means. According to the present invention, it is possible to make a user aware of the preparation data capable of using the remaining medicine as a target of the next mixed injection process, and to support efficient use of the medicine in the medicine container. be able to.

Further, when the mixed injection management device selects the preparation data including the same type of drug as the remaining drug in the prescription drug as a target of the mixed injection process and satisfies a preset use condition, the residual drug in the mixed injection process A configuration including a remaining medicine using means for using a medicine is conceivable. This makes it possible to automatically exclude the use of the remaining medicine when the use conditions are not satisfied. Specifically, it is conceivable that the use condition includes at least that the expiration date set in advance for the remaining medicine has not passed. Thereby, for example, it is possible to set as the use condition that the expiration date of the remaining drug has not passed, and to set only the remaining drug for which the expiration date has not passed as the target of use. Further, a configuration in which the mixed injection management device includes a remaining amount detecting unit that detects the remaining amount of the remaining medicine in the medicine container after the mixed injection processing is performed is conceivable. In this case, the use condition is calculated based on the preparation data and the predetermined amount of the drug container. The remaining amount of the remaining drug in the drug container and the remaining amount in the drug container detected by the remaining amount detecting means It is conceivable that the difference from the remaining amount of the remaining drug is within a preset range. Thereby, the difference between the remaining amount of the remaining drug actually remaining in the drug container and the calculated value of the remaining amount based on the preparation data and the predetermined amount of the drug container exceeds a predetermined allowable amount. In some cases, the use of the remaining drug is prevented.

Further, it is conceivable that the determination means determines whether or not the medicine remains in the medicine container based on the preparation data and the predetermined amount of the medicine container before execution of the mixed injection process. Thereby, the display control means can preferentially display the preparation data that can use the remaining medicine among the preparation data selection candidates before the end of the past mixed injection process. Further, in the configuration in which the mixed injection management device includes a remaining amount detecting unit that detects the weight of the remaining medicine in the drug container after the mixed injection process is performed, the determination unit is detected by the remaining amount detecting unit. It is also conceivable to determine whether or not the medicine remains in the medicine container based on the remaining amount of the remaining medicine in the medicine container. In this case, the display control means preferentially displays the preparation data that can use the remaining medicine based on the remaining amount of the remaining medicine actually remaining in the medicine container after the mixed injection process.

It is conceivable that the display control means causes the display means to display selection candidates for the preparation data in a display order in which the preparation data including the same kind of drug as the remaining medicine in the prescription drug is in the upper rank. Thereby, the user can grasp | ascertain easily the said preparation data which can use the said residual chemical | medical agent. Further, the display control means may display the preparation data including the same kind of drug as the remaining drug as a prescription drug in the selection candidate of the preparation data to be the target of the mixed injection process, arranged in a preset sort condition. It is done. Thereby, the user can easily grasp the preparation data having a higher priority among the preparation data in which the remaining drug can be used according to the sorting condition. Specifically, it is conceivable that the sorting condition is a condition in which the one with the earlier prescription drug dosing date or preparation date in the preparation data is higher. In addition, the sort condition may be a condition in which the prescription category of the preparation data is outpatient than the case where the prescription category of the preparation data is hospitalization. Thereby, the user can easily grasp the order of the dispensing data to be prioritized according to the medication date and time, the preparation date and time, the prescription classification, and the like. Moreover, it is possible that the said mixed injection management apparatus is provided with the predetermined amount information memory | storage means in which the predetermined amount information which shows the said predetermined amount for every kind of medicine was memorize | stored. In this case, the determination means determines whether or not the drug remains in the drug container based on the dispensed amount of the drug based on the preparation data and the predetermined amount information stored in the predetermined amount storage unit. Is possible.

The mixed injection management device stores a remaining amount storage means for storing the remaining amount of the remaining medicine determined to remain in the medicine container by the determination means, and a dispensing amount of the medicine based on the preparation data and the remaining amount. It is conceivable to include a deficient amount display means for displaying the amount of the drug deficient or the number of the drug containers based on the remaining amount of the remaining drug stored in the amount storage means. Accordingly, since the user can easily grasp whether or not the drug container needs to be loaded when using the remaining drug, and the number of the drug containers, the drug container is insufficient when using the remaining drug. You don't have to think about the number of yourself. On the other hand, the mixed injection management device returns a predetermined return of the unused medicine container among the medicine containers loaded according to the amount of medicine dispensed based on the preparation data after the remaining medicine is used. It is conceivable to provide return processing means for returning from the mouth. As a result, since the surplus drug containers are automatically returned, the user is always required according to the preparation data without being aware of the number of drug containers to be loaded when using the remaining drug. The normal operation of determining and loading the number of drug containers can be performed.

As a method for preferentially displaying the preparation data including the same type of drug as the remaining drug in the prescription drug, the display control means displays only the preparation data including the same type of drug as the remaining drug as the prescription drug. It can also be displayed on the means. As a result, the user can easily confirm only the preparation data in which the remaining drug can be used. By the way, when the residual drug is a mixed drug of a plurality of drugs or solvents, the display control means preferentially displays preparation data including a mixed drug having the same component and mixing ratio as the prescription drug. It is possible to make it. Thereby, when the said remaining medicine arises also about the said mixing medicine, it becomes possible to support the efficient use which does not waste the remaining medicine.

By the way, this invention may be grasped | ascertained as invention of the co-infusion apparatus provided with the said co-infusion management apparatus and the co-infusion process part which performs the said co-infusion process. That is, the co-infusion apparatus includes the determination unit and the display control unit. Whether the drug remains in the drug container used in the mixed injection process in which the drug indicated in the preparation data is injected from one or a plurality of drug containers containing the predetermined amount of the drug into the infusion container. Judge whether or not. The display control means uses, as a prescription drug, a medicine of the same type as the remaining medicine that has been determined to remain in the medicine container by the determination means in the past mixed injection process among the selection candidates of the preparation data to be subjected to the mixed injection process The prepared preparation data is preferentially displayed on the display means. Here, the mixed injection processing unit holds the medicine container and can transport the medicine container to an arbitrary position, and holds the syringe and the medicine from the medicine container by the syringe. And a second robot arm capable of performing suction of the liquid and injection of the medicine into the infusion container. In this case, the mixed injection management device moves the drug container determined by the determination means to retain the remaining drug to a standby position set in advance by the first robot arm, and moves the drug container to the first The robot arm can be taken out from the standby position.

Further, the present invention may be understood as a mixed injection management program for causing a computer to function as each of the above means. That is, the mixed injection management program according to the present invention is used in the mixed injection process in which the drug indicated in the preparation data is injected into the infusion container from one or a plurality of drug containers in which a predetermined amount of the drug is stored in the computer. A determination step of determining whether or not the drug remains in the medicine container; and a determination step among the selection candidates of the preparation data to be subjected to the mixed injection process; This is a program for executing a display control step for preferentially displaying on the display means preparation data including a prescription drug containing the same type of drug as the remaining drug. Further, the mixed injection management program causes the computer to perform the mixed injection processing when the preparation data including the same type of drug as the remaining drug in the prescription drug is selected as the target of the mixed injection processing and satisfies a preset use condition. It is conceivable that this is a program for further executing the remaining medicine using step of using the remaining medicine.

In the mixed injection process, as described below, the anti-cancer indicated in the preparation data is performed by controlling the first robot arm 21 and the second robot arm 22 by the second controller 500. A drug such as a drug is injected into the infusion bag 12 from one or a plurality of the drug containers 10 containing a predetermined amount of the drug.

[Mix Injection Process Using Ampoule 10A] First, the co-infusion process when injecting the medicinal solution contained in the ampoule 10A into the infusion bag 12 will be described.

The second control unit 500 opens the shutter 111 when the container 101 is supplied to the container transport unit 110. Then, the container transport section 110 raises the medicine placement section 102 of the container 101 by the tray lifting / lowering section 112 and exposes it to the mixed injection processing chamber 104.

Next, the first robot arm 21 grasps the syringe 11 placed on the medicine placement section 102 exposed in the mixed injection processing chamber 104 and temporarily places it on the placement shelf 33. The first robot arm 21 sets the ampoule 10 A placed on the medicine placing unit 102 on the medicine reading unit 34. As a result, the medicine reading unit 34 reads information such as the type of medicine contained in the ampoule 10A. In the first robot arm 21, the first injection needle 11 c is set on the injection needle attaching / detaching device 43, and the second injection needle 11 c is temporarily placed on the placement shelf 33. Note that a cap is attached to the injection needle 11 c placed on the medicine placement section 102, and the cap is attached and detached by the injection needle attaching / detaching device 43.

By the way, the second control unit 500 grasps the position and orientation of the ampoule 10A and the syringe 11 placed on the medicine placement unit 102 by the image recognition process for the captured image of the tray confirmation camera 41. In particular, every time the ampule 10A or the syringe 11 is taken out from the medicine placement section 102, the second control section 500 takes an image of the medicine placement section 102 with the tray confirmation camera 41, and updates the latest from the captured image. The position and direction of the ampule 10A and the syringe 11 are grasped.

Then, the second control unit 500 performs the image recognition process to determine whether or not all articles on the medicine placement unit 102 have been taken out. Note that the second control unit 500 is configured so that the ampule 10A, the syringe 11, and the injection needle 11c are mounted on the drug by the number of drugs, syringes, and needles indicated in the preparation content information of the preparation data. It may be determined based on an image captured by the tray check camera 41 whether or not the image is present in the placement unit 102. If it does not exist, the second controller 500 may display that fact on the touch panel monitor 14. Further, before the syringe 11 and the like in the medicine placement section 102 are taken out by the first robot arm 21, the medicine placement section 102 is photographed by the tray confirmation camera 41. Therefore, the ampule 10A, The shortage of the syringe 11 and the injection needle 11c can be notified early.

Subsequently, when all of the ampule 10A, the syringe 11, the injection needle 11c, and the like are taken out from the medicine placement section 102, the container transport section 110 moves the medicine placement section 102 to the tray lifting / lowering section 112. Lower and return to the container 101. Meanwhile, the second control unit 500 closes the shutter 111 and causes the container transport unit 110 to transport the container 101 to the container transport end unit 110a. After the container 101 has moved to the container transfer terminal portion 110a, the container transfer unit 110 uses the mixed injection port of the infusion bag 12 held by the infusion bag holding unit 103 of the container 101 as the mixed injection processing chamber. It is located in the mixed injection communication port 37 formed in 104.

Then, the second robot arm 22 moves the ampule 10 A set in the medicine reading unit 34 to the mounting table 33.

The second robot arm 22 moves the syringe 11 to the injection needle attaching / detaching device 43 to attach the injection needle 11 c to the syringe 11. As described above, since the injection needle 11c is exchanged between when the drug is sucked from the ampule 10A and when the infusion is injected into the infusion bag 12, fragments of the ampule 10A are mixed into the infusion bag 12. It is prevented.

Then, the second robot arm 22 punctures the injection needle 11c of the syringe 11 into the mixed injection port of the infusion bag 12 conveyed to the container conveyance terminal portion 110a, and mixes the drug in the syringe 11 with the mixture. Inject into the infusion bag 12. On the other hand, the second controller 500 opens the dust cover 132a, and the first robot arm 21 drops the ampoule 10A into the dust storage chamber 13a and discards it. The second robot arm 22 moves the syringe 11 to the syringe needle attaching / detaching device 43 to attach the cap to the syringe needle 11c of the syringe 11, and then moves the syringe 11 to the dust storage chamber. Drop into 13a and discard.

[Mix Injection Process Using Vial Bottle 10B] Subsequently, a co-infusion process when injecting a mixed medicine produced by mixing powder contained in the vial bottle 10B with an infusion solution into the infusion bag 12 will be described.

Next, the first robot arm 21 grasps the syringe 11 placed on the medicine placement section 102 exposed in the mixed injection processing chamber 104 and temporarily places it on the placement shelf 33. The first robot arm 21 sets the vial 10 B placed on the medicine placing unit 102 on the medicine reading unit 34. Thereby, the medicine reading unit 34 reads information such as the type of medicine stored in the vial bottle 10B.

Subsequently, when all the vials 10B, the syringe 11, the injection needle 11c, and the like are taken out from the medicine placement section 102, the container transport section 110 moves the medicine placement section 102 to the tray lifting / lowering section 112. To return to the container 101. Meanwhile, the second control unit 500 closes the shutter 111 and causes the container transport unit 110 to transport the container 101 to the container transport end unit 110a. After the container 101 has moved to the container transfer terminal portion 110a, the container transfer unit 110 uses the mixed injection port of the infusion bag 12 held by the infusion bag holding unit 103 of the container 101 as the mixed injection processing chamber. It is located at the mixed injection communication port 37 formed at 104.

Then, the second robot arm 22 moves the vial 10 B set in the medicine reading unit 34 to the mounting table 33. On the other hand, in parallel with this movement process, the first robot arm 21 sets the injection needle 11 c of the syringe 11 placed on the medicine placement unit 102 to the injection needle attaching / detaching device 43.

Next, the first robot arm 21 takes out the syringe 11 from the mounting table 33 and sets it on the second robot arm 22. Then, the second robot arm 22 moves the syringe 11 to the syringe needle attaching / detaching device 43 to set the syringe needle 11 c in the syringe 11. Thereafter, the second robot arm 22 moves the syringe 11 to the needle bending detection unit 36 to detect the presence or absence of the bending of the injection needle 11c.

Subsequently, the second robot arm 22 punctures the injection needle 11c of the syringe 11 into the co-infusion port of the infusion bag 12 transported to the container transport terminal portion 110a, and the preparation data from the infusion bag 12 Aspirate the infusion of the indicated volume. On the other hand, the first robot arm 21 takes out the vial 10 B placed on the placing table 33.

Then, the first robot arm 21 and the second robot arm 22 bring the vial bottle 10B and the syringe 11 close to each other and puncture the vial bottle 10B with the injection needle 11c of the syringe 11. Thereafter, the second robot arm 22 injects the infusion solution in the syringe 11 into the vial bottle 10B by operating the plunger 11b. Thereby, a mixed medicine is produced in the vial bottle 10B. At this time, the posture of the syringe 11 and the vial bottle 10B is such that the injection needle 11c of the syringe 11 is directed vertically downward, and the mouth of the vial bottle 10B is directed vertically upward.

Next, the first robot arm 22 sets the vial bottle 10 B into which the infusion solution has been injected into the stirring device 32. Thereby, in the said stirring apparatus 32, the chemical | medical agent and infusion in the said vial bottle 10B are stirred. When the stirring by the stirring device 32 is completed, the first robot arm 21 takes out the vial 10B from the stirring device 32. The first robot arm 21 and the robot arm 22 bring the vial bottle 10B and the syringe 11 close to each other, and puncture the vial bottle 10B with the injection needle 11c of the syringe 11. Thereafter, the second robot arm 22 operates the plunger 11b to suck the mixed drug in the vial bottle 10B with the syringe 11. At this time, the postures of the syringe 11 and the vial bottle 10B are such that the vial bottle 10B has the mouth portion directed vertically downward and the injection needle 11c of the syringe 11 directed vertically upward.

Then, the second robot arm 22 punctures the injection needle 11c of the syringe 11 into the mixed injection port of the infusion bag 12 conveyed to the container conveyance terminal portion 110a, and mixes the drug in the syringe 11 with the mixture. Inject into the infusion bag 12. Meanwhile, the second controller 500 opens the dust lid 132a, and the first robot arm 21 drops the vial 10B into the dust storage chamber 13a and discards it. The second robot arm 22 sets the syringe 11 on the syringe needle attachment / detachment device 43, attaches the cap to the syringe needle 11c of the syringe 11, and then moves the syringe 11 to the dust storage chamber. Drop into 13a and discard.

In addition, the mixed injection process when injecting the drug solution stored in the vial bottle 10B into the infusion bag 12 generates a mixed drug that sucks the infusion solution from the infusion bag 12 and injects it into the vial bottle 10B to be stirred. This is the same as the co-infusion process when injecting the powder contained in the vial bottle 10B into the infusion bag 12 except that the process for performing is not executed.

Hereinafter, an example of the procedure of the mixed injection management process and the mixed injection control process executed by the first control unit 400 and the second control unit 500 in the mixed injection apparatus 1 will be described with reference to FIGS. Here, steps S11, S12, S13... Shown in FIG. 19 are steps of the mixed injection management process executed by the first control unit 400, and steps S21, S22, S23. The identification code | symbol of the procedure of the said mixed injection control process which the 2nd control part 500 performs is shown.

Note that the processing sharing of each of the first control unit 400 and the second control unit 500 described here is merely an example, and each processing procedure of the mixed injection management process and the mixed injection control process is the same as that of the first control unit 400 and It may be executed by one of the second control units 500. In addition, the mixed injection management apparatus 100 includes one control unit or three or more control units, and the mixed injection management process and the mixed injection control process are executed by the control unit as another embodiment. . Furthermore, part or all of the processing executed by the first control unit 400 and the second control unit 500 may be executed by an electronic circuit such as an ASIC or DSP.

[Mixed Injection Management Process] <Step S11> First, as shown in FIG. 19, in step S11, the first control unit 400 determines whether or not the preparation data has been input. For example, the preparation data is input when the preparation data is received from the host system 600 or when the barcode indicating the preparation data is read by the barcode reader 204.

Here, if the said 1st control part 400 judges that the said preparation data was input (Yes side of S11), it will transfer a process to step S12, and if the said preparation data is not input (No side of S11) Then, the process proceeds to step S13.

<Step S12> In step S12, the first controller 400 generates a prescription selection screen M1 in which selection candidates for the preparation data to be subjected to the mixed injection process in the mixed injection device 1 are arranged, and the display 203 Display. Here, when there are a plurality of selection candidates for the preparation data to be subjected to the mixed injection process in the mixed injection device 1, the preparation data of the selection candidates are arranged according to the preset sorting conditions on the prescription selection screen M1. Displayed with status. The sort condition is determined, for example, by any one or a combination of a preparation date / time, a medication date / time, a prescription category, and a preparation data issue date / time by the mixed injection device 1. The user refers to the prescription selection screen M1 and puts the number of the drug containers 10 and the syringes 11 necessary for the preparation data displayed on the top of the prescription selection screen M1 in the mixed injection device 1 into the container 101. The container 101 is loaded into the mixed injection processing unit 300.

FIG. 20 is a diagram showing an example of the prescription selection screen M1. In the prescription selection screen M1 shown in FIG. 20, a search condition display unit D1 in which an input field of search conditions for narrowing down the selection candidates is arranged, and a prescription display unit in which the preparation data of the selection candidates are arranged side by side D2 and the like are included. In the search condition display section D1, an extraction key D11 for starting an extraction process for narrowing down selection candidates for the preparation data according to the search conditions is arranged.

In addition, the prescription display unit D2 indicates whether or not the prescription drug includes preparation data that includes a prescription drug containing the same type of drug as the residual drug remaining in the drug container 10 in the mixed injection process that has been performed in the past. Presence / absence display portion D21 is arranged. That is, the remaining drug presence / absence display unit D21 indicates whether or not the data is preparation data that can execute the mixed injection process using the remaining drug. For example, in the remaining drug presence / absence display portion D21, information such as characters, symbols, figures, or illustrations indicates whether or not the remaining drug is preparation data that can be used.

By the way, there may be a case where the operation of using the remaining medicine in the next mixed injection process is not necessary. Therefore, the first control unit 400 can change ON / OFF of the remaining medicine use function for using the remaining medicine generated in the past mixed injection process in the next mixed injection process according to the user operation in the initial setting or the like. It is. Thereby, the user can arbitrarily switch whether to receive support for using the remaining medicine in the next mixed injection process. The first control unit 400 may be configured to be able to switch on / off the remaining medicine use function in accordance with a user operation on the prescription selection screen M1. The first control unit 400 executes processing after step S16 described later when the remaining medicine use function is ON, and after step S16 described later when the remaining medicine use function is OFF. It is conceivable that the above process is not executed. Further, when the remaining medicine use function is OFF, the first control section 400 may hide the remaining medicine presence / absence display section D21 on the prescription selection screen M1.

In addition, the first control unit 400 has a sort condition setting function for setting the sort condition in accordance with a user operation on the operation unit 405 in an initial setting or the like. For example, the first control unit 400 can change the display order of the preparation data by changing the sort condition also on the prescription selection screen M1. That is, the first control unit 400, when the display location of each display item of the prescription display unit D2 is operated by the mouse or the touch panel of the operation unit 405, ascending order or descending order for the operated display item. It is possible to rearrange the preparation data so that

<Step S13> In step S13, the first control unit 400 determines whether or not an extraction start operation for extracting specific preparation data from the preparation data of selection candidates has been performed. Specifically, the first control unit 400 performs the extraction according to whether the search condition is set in the search condition display unit D1 and the extraction key D11 is operated by a user operation on the operation unit 405. Determine whether there is a start operation.

Here, when the first control unit 400 determines that the extraction start operation has been performed (Yes side of S13), the process proceeds to step S131, and if the extraction start operation has not been performed (No side of S13). Then, the process proceeds to step S14.

<Step S131> In step S131, the first control unit 400 extracts the preparation data as selection candidates according to the search condition. For example, the prescription selection screen M1 shown in FIG. 20 shows that the result of the extraction of the preparation data is performed by inputting “2012/07/12” in the dispensing date input field indicating the scheduled execution date of the mixed injection process. It is a displayed example.

<Step S132> In step S132, the first controller 400 displays the prescription selection screen M1 on which the preparation data extracted in step S131 is arranged, and returns the process to step S11. For example, the prescription selection screen M1 shown in FIG. 20 displays a plurality of the preparation data extracted in the step S131 when it is set in advance that the medication dates are arranged and displayed from the top in order from the earliest. It is an example.

<Step S14> On the other hand, in step S14, the first control unit 400 determines whether or not a user operation for selecting any of the preparation data has been performed on the operation unit 405. When the first control unit 400 determines that the preparation data selection operation has been performed (Yes in S14), the process proceeds to step S15 until the preparation data selection operation is performed. (No side of S14) shifts the process to step S11.

<Step S15> In step S15, the first control unit 400 transmits the preparation data selected by the selection operation in step S14 to the second control unit 500. The first control unit 400 generates not only the preparation data itself but also the mixed injection control data for causing the mixed injection processing unit 300 to execute the mixed injection processing based on the preparation data, and the mixed injection control data is used as the mixed injection control data. It may be transmitted to the second control unit 500.

<Step S16> Next, in Step S16, the first control unit 400 uses the inside of the medicine container 10 used when the mixed injection process for the preparation data selected in Step S14 is performed. It is determined whether or not the drug remains. The said 1st control part 400 when performing the determination process which concerns here corresponds to a determination means. Specifically, the first control unit 400 determines the medicine container based on the medicine dispensing amount based on the preparation data and a predetermined amount of medicine stored in the medicine container 10 in the data storage unit 404. It is determined before the end of the co-infusion process whether or not a drug less than the predetermined amount remains in 10. Thereby, even before the mixed injection process is completed, the adjustment data that can use the remaining medicine is displayed when displaying the selection candidate to be the next target of the mixed injection process in step S181 or step S19 described later. It is possible to display with priority.

For example, when the amount of the medicine to be dispensed is 20 ml and the predetermined amount of the medicine container 10 is 30 ml, the first control unit 400 determines that the amount of the medicine to be dispensed is 30 ml and the amount to be dispensed. It is determined that 10 ml of medicine remains in the medicine container 10 based on the difference from 40 ml. In addition, when the amount of the medicine to be dispensed is 40 ml and the predetermined amount of the medicine container 10 is 30 ml, the first control unit 400 determines that the total amount of the two medicine containers 10 is 60 ml and the amount to be dispensed. It is determined that 20 ml of medicine remains in the medicine container 10 based on the difference from 40 ml.

Here, when the first control unit 400 determines that the drug remains in the drug container 10 (Yes side of S16), the first control unit 400 shifts the process to step S17 and determines that no drug remains in the drug container 10. Then (No side of S16), the process is shifted to step S11. As described above, the first control unit 400 determines whether or not a medicine remains in the medicine container 10 when the mixed injection process ends before the mixed injection process ends. Therefore, the process after step S17 is executed before the user starts preparation of the medicine and instrument necessary for the next mixed injection process.

<Step S17> In step S17, the first control unit 400 causes the data storage unit 404 to store the remaining medicine information regarding the remaining medicine determined to remain in the step S16. Specifically, the remaining medicine information includes, for example, various types of information such as the type of remaining medicine, the remaining amount, the opening date and time, and the expiration date. When the remaining drug is a mixed drug, the remaining drug information includes, for example, various information such as components of the mixed drug (drug name, solvent name), solvent amount, remaining amount, opening date / time, and expiration date. included. The data storage unit 404 is an example of a remaining amount storage unit. In the mixed drug, since the mixing ratio in the mixed drug is specified according to the drug name and the solvent amount, the case where the solvent amount is stored as the residual information will be described as an example. The mixing ratio may be stored.

By the way, the first control unit 400 deletes each of the remaining medicine information stored in the data storage unit 404 on the condition that the expiration date of the remaining medicine information has passed, and includes the remaining medicine information in the remaining medicine information. It is conceivable that a control signal for discarding the corresponding medicine container 10 is input to the second control unit 500. Accordingly, the second control unit 500 controls the first robot arm 21 or the second robot arm 22 and discards the medicine container 10 whose expiration date has passed. At this time, the first control unit 400 follows the display order of the preparation data in the prescription display unit D2 displayed on the prescription selection screen M1 when there is no residual drug whose expiration date has passed. Update the display order.

<Step S18> Subsequently, in Step S18, the first control unit 400 determines whether or not the remaining drug remaining in the drug container 10 is a mixed drug in which a plurality of drugs or solvents are mixed. . Here, when the first control unit 400 determines that the remaining drug is the mixed drug (Yes side of S18), the first control unit 400 moves the process to step S19 and determines that the remaining drug is not the mixed drug. (No side of S18), the process proceeds to step S181.

<Step S181> In step S181, the first control unit 400 determines that among the selection candidates of the preparation data to be subjected to the mixed injection process, it remains in the medicine container 10 in the past mixed injection process in step S16. Preparation data that contains the same type of drug as the remaining drug as a prescription is displayed preferentially. Here, the first control unit 400 when executing the display process corresponds to a display control means. Specifically, the first control unit 400 selects the preparation data selection candidates in the display order in which the selection candidates of the preparation data including the same type of medicine as the prescription medicine remaining in the medicine container 10 are higher. Is displayed on the prescription selection screen M1 of the display 403. In addition, the first control unit 400 uses the remaining drug in the remaining drug presence / absence display unit D21 corresponding to the preparation data in which the same type of drug as the remaining drug remaining in the drug container 10 is included as a prescription drug. Display information indicating that it is possible. Thereby, the user can grasp | ascertain easily the said preparation data which can use the said residual chemical | medical agent.

For example, in the step S181, the first control unit 400 searches whether there is preparation data in which a medicine of the same type as the remaining medicine remaining in the medicine container 10 is included as a prescription medicine. And when the said preparation data are obtained as a search result 1 or more, the said 1st control part 400 changes the display content of the said prescription selection screen M1 so that the display position of the preparation data may become the highest. Further, as a method for preferentially displaying preparation data in which the same kind of drug as the remaining drug remaining in the drug container 10 is included as a prescription drug, the first control unit 400 remains in the drug container 10. It is also conceivable to display only the preparation data containing the same type of drug as the remaining drug as a prescription drug on the display device 26. As a result, the user can easily confirm only the preparation data in which the remaining drug can be used.

Here, when there are a plurality of pieces of preparation data extracted as the search results, the first control unit 400 determines the arrangement order of the plurality of pieces of preparation data according to the sort condition, as in step S12. Thereby, it is possible to display the candidate of the said preparation data which should be prioritized according to the said sort conditions on the uppermost stage. As described above, the sorting condition is, for example, a condition in which the earlier one of the prescription drug administration date or preparation date of the preparation data is higher. The sort condition may be a condition in which the prescription category of the preparation data is outpatient than the prescription category of the preparation data is hospitalized. Thereby, the user can easily grasp the order of the dispensing data to be prioritized according to the medication date and time, the preparation date and time, the prescription classification, and the like.

In addition, when the preparation data in which the same kind of medicine as the residual medicine remaining in the medicine container 10 is not extracted as the prescription medicine, the first control unit 400 does not change the display content of the prescription selection screen M1. It is possible. In this case, the first control unit 400 determines that the remaining medicine cannot be used, and does not place the medicine container 10 on the placement shelf 33, but stores the medicine container 10 in the garbage storage. It is also conceivable to transmit a control signal for causing the chamber 13a to be discarded to the second control unit 500.

<Step S19> On the other hand, in Step S19, the first control unit 400 gives priority to preparation data including prescription drugs having the same components and mixing ratio as the mixed drug remaining in the drug container 10. To display automatically. Here, the first control unit 400 when executing the display process corresponds to a display control means. At this time, the first control unit 400 determines whether the mixing ratio is the same, for example, according to the drug name and solvent amount stored in the remaining information and the drug name and solvent amount in the preparation data. To do.

Specifically, the first control unit 400 displays, as in the step S181, higher-order preparation data including a prescription drug containing a drug having the same component and mixing ratio as the remaining drug remaining in the drug container 10. The preparation data selection candidates are displayed on the prescription selection screen M1 of the display 403 in order. In addition, the first control unit 400 displays the remaining drug in the remaining drug presence / absence display unit D21 corresponding to preparation data in which a drug having the same component and mixing ratio as the remaining drug remaining in the drug container 10 is included as a prescription drug. Information indicating that it is possible to use is displayed. Also in step S19, as in step S181, when there are a plurality of the prepared data, the first control unit 400 determines the arrangement order of the plurality of prepared data according to the sorting condition.

By the way, in the mixed injection management apparatus 100, the second control unit 500 determines whether or not the medicine remains in the medicine container 10 based on the weight of the medicine container 10 after the mixed injection processing is performed in Step S16. It is possible to judge whether. Specifically, the second control unit 500 places the drug container 10 on the weighing meter 35 using the first robot arm 21 or the second robot arm 22 after the mixed injection process is completed, and the drug The weight of the container 10 is measured. The second control unit 500 calculates the difference between the empty weight of the medicine container 10 stored in the medicine master and the weight of the medicine container 10 after the mixed injection process is performed. It is possible to detect the remaining amount of the medicine in the medicine container 10 after execution of the mixed injection process. Here, the second control unit 500 when executing the detection process is an example of a remaining amount detection unit. Accordingly, the first control unit 400 preferentially displays the preparation data that can use the remaining medicine based on the remaining amount of the remaining medicine actually remaining in the medicine container 10 after the mixed injection process. Is possible. In addition, the detection method of the residual amount of the medicine in the medicine container 10 is not limited to this. For example, the medicine container 10 is imaged using a camera, and the medicine in the medicine container 10 is detected based on the captured image. It is also conceivable to detect the remaining amount. In addition, the second control unit 500 may determine the amount of medicine (medicine in the syringe 11) acquired based on the weight of the syringe 11 measured by the weighing meter 35 or an image captured by the syringe confirmation camera 42. It is also possible to detect the remaining amount of the medicine in the medicine container 10 by calculating the difference between the amount extracted from the container 10 and the predetermined amount of the medicine container 10.

[Mixed Injection Control Process] Next, an example of the procedure of the mixed injection control process executed by the second control unit 500 will be described with reference to FIG.

<Step S21> In step S21, the second control unit 500 determines whether the preparation data is input from the first control unit 400. Here, if the said 2nd control part 500 judges that the said preparation data was input (Yes side of S21), it will transfer a process to step S22. On the other hand, the second controller 500 repeatedly executes the determination process of step S21 until the preparation data is input (No side of S21).

<Step S22> In Step S22, is it possible for the second control unit 500 to use the remaining medicine remaining in the mixed injection process performed in the past in the mixed injection process for the preparation data? Judge whether or not. Specifically, the second control unit 500 includes, in a prescription drug, the same type of drug as the remaining drug based on the remaining drug information stored in the data storage unit 404 by the first control unit 400. It is determined whether or not the dispensing data has been selected as the target of the mixed injection process. Further, the second controller 500 determines whether or not the content of the remaining medicine information satisfies a preset use condition. The use condition is, for example, that the expiration date of the remaining medicine stored in the remaining medicine information has not passed, or that a predetermined time has not passed since the opening date of the remaining medicine. Thereby, for example, it is possible to set as the use condition that the expiration date of the remaining drug has not passed, and to set only the remaining drug for which the expiration date has not passed as the target of use.

That is, the second control unit 500 uses the dispensing data including the same type of drug as the remaining drug in the prescription drug as the target of the mixed injection process, and the usage condition in which the content of the remaining drug information is set in advance. If the condition is satisfied, it is determined that the remaining drug can be used. This makes it possible to automatically exclude the use of the remaining medicine when the use conditions are not satisfied. The first control unit 400 determines whether or not the remaining drug can be used, and whether or not the second control unit 500 can use the remaining drug from the first control unit 400. A control signal may be received.

Further, after the execution of the co-infusion process, the second control unit 500 after the use condition is calculated based on the preparation data and the predetermined amount of the medicine container 10 and the remaining amount of the medicine remaining in the medicine container 10. It is also conceivable that the difference between the remaining amount of the remaining medicine in the medicine container 10 detected by the above is within a preset range. Thereby, the difference between the remaining amount of the remaining medicine actually remaining in the medicine container 10 and the calculated value (predicted value) of the remaining amount based on the preparation data and the predetermined amount of the medicine container 10 is obtained. When the predetermined allowable amount is exceeded, it is possible to prevent the use of the remaining drug. For example, when the medicine is aspirated from the medicine container 10 by the syringe 11, the medicine leaks, and the remaining amount of the remaining medicine actually remaining in the medicine container 10 after the co-infusion processing is smaller than the calculated value. In such a case, it is possible to determine that before the start of the next mixed injection process, so that it is possible to prevent an error in which a shortage of medicine is found after the mixed injection process is started. Note that the usage conditions are calculated based on the preparation data and the predetermined amount of the medicine container 10, and the remaining amount of the medicine in the medicine container 10 and the syringe confirmation camera during the mixed injection process. The difference between the amount of medicine sucked into the syringe 11 imaged at 42 and the remaining amount of the remaining medicine in the medicine container 10 calculated based on the predetermined amount of the medicine container 10 is preset. It is also possible to include being within range.

Here, the second control unit 500
If it is determined that the remaining drug can be used (Yes in S22), the process proceeds to step S23. If it is determined that the remaining drug cannot be used (No in S22), the process proceeds to step S221. Transition.

<Step S221> In step S221, the second control unit 500 controls the mixed injection processing unit 300 based on the preparation data input from the first control unit 400 to thereby remove the infusion bag from the drug container 10. The normal mixed injection process of injecting the drug into the No. 12 is executed. Specifically, in the mixed injection process, the second control unit 500 sucks the medicine indicated in the preparation data from one or a plurality of the medicine containers 10 placed on the container 101 by the syringe 11, The syringe 11 is injected into the infusion bag 12.

<Step S23> On the other hand, in Step S23, the second control unit 500 uses the remaining medicine by controlling the mixed injection processing unit 300 based on the preparation data input from the first control unit 400. Then, the exceptional mixed injection process for injecting the drug into the infusion bag 12 is executed. That is, the second control unit 500 determines the remaining drug in the mixed injection process when the preparation data including the same type of drug as the remaining drug is selected as the target of the mixed injection process and satisfies the use condition. Execute the process to be used. The said 2nd control part 500 when performing the process which concerns here corresponds to a residual medicine use means.

Specifically, in the mixed injection process in step S23, the second control unit 500 transfers the medicine indicated in the preparation data from the medicine container 10 placed on the placing table 33 in step S25 described later. The syringe 11 is aspirated and injected from the syringe 11 into the infusion bag 12. However, when the remaining amount of the medicine in the medicine container 10 placed on the placement table 33 is not sufficient, the second control part 500 is provided with one or a plurality of medicines placed on the medicine placement section 102. The mixed injection process is continued using the medicine in the medicine container 10.

<Step S24> When the mixed injection process is completed, in step S24, the second control unit 500 determines whether or not the medicine remains in the medicine container 10. The determination process in step S24 may be the same process as in step S16 executed by the first control unit 400, but indicates whether or not the remaining medicine is generated from the first control unit 400. A control signal may be received.

Here, when the second control unit 500 determines that the medicine remains (Yes side of S24), the process proceeds to step S25, and when it is determined that the medicine does not remain (No side of S24), The process proceeds to step S241.

<Step S25> When the drug remains in the drug container 10, in the subsequent step S25, the second control unit 500 controls the first robot arm 21 so that the drug container 10 can be used again. Then, it is placed on the placement shelf 33. In addition, the second control unit 500 includes the name of the medicine, the remaining amount of the medicine in the medicine container 10, the placement position of the medicine container 10, the opening date and time of the medicine container 10, and the inside of the medicine container 10 Various information such as the expiration date of the remaining medicine is stored in the data storage unit 504.

<Step S241> On the other hand, if no medicine remains in the medicine container 10, the second control unit 500 discards the medicine container 10 in the garbage storage chamber 13a by the first robot arm 21 in Step S241. That is, when the medicine in the medicine container 10 is not used up, the medicine container 10 is returned to the placement shelf 33, and when the medicine in the medicine container 10 is used up, the medicine container 10 is discarded. .

As described above, in the mixed injection device 1, the mixed injection control device 100 executes the mixed injection management process and the mixed injection control process, so that the remaining medicine remaining in the previous mixed injection process can be used. Preparation data is preferentially displayed as a selection candidate for the next mixed injection process. As a result, the mixed injection device 1 can make the user aware of the preparation data that can use the remaining drug as the target of the next mixed injection process, so that the drug in the drug container 10 can be efficiently used. Can support use.

[Operation Example of Mixed Injection Device 1] FIG. 22 is a diagram for explaining an actual operation example when the mixed injection management process and the mixed injection control process are executed by the mixed injection control apparatus 100. 22A shows an example of preparation data, FIG. 22B shows an example of residual drug information, and FIGS. 22C to 22E show examples of display of a part of the prescription display part D2. Note that the information shown in FIG. 22 omits items of information that are less relevant to the present case for convenience of explanation.

Here, as shown in FIG. 22A, a case is considered in which preparation data Rp1 to Rp4 are input to the first control unit 400 as selection candidates for the dispensing data to be subjected to the mixed injection process. For example, in the preparation data Rp1, a predetermined amount of the ampule 10A containing a medicine having a medicine name of “5-FU injection 1000 mg”, a dispensing amount of “15 ml”, and the medicine name “5-FU injection 1000 mg”. Is shown to be “20 ml”. In addition, in the preparation data Rp2, the ampule in which the drug name to be prepared is “Kiloside N (registered trademark) Note 1 g”, the amount to be dispensed is “50 ml”, and the drug name “Kiloside N Note 1 g” is accommodated. It is shown that the default amount of 10A is “50 ml”. The first control unit 400 obtains a predetermined amount corresponding to the drug name “5-FU injection 1000 mg”, “Kiloside N injection 1 g”, and the like from the medicine master stored in the data storage unit 404. May be. Further, the first control unit 400 may acquire the predetermined amount from the barcode of the medicine container 10 by the barcode reader 34b.

When the first control unit 400 selects the preparation data Rp1 as the target of the mixed injection process, the first control unit 400 calculates a difference (5 ml) between the payout amount and the predetermined amount. . Accordingly, the first control unit 400 determines that the drug name “5-FU injection 1000 mg” remains “5 ml” in the ampoule 10A, and informs that information about the remaining medicine (see FIG. 22B). Is stored in the data storage unit 404. In the remaining medicine information shown in FIG. 22 (B), the medicine with the medicine name “5-FU injection 1000 mg” remains in the ampoule 10A by the remaining amount “5 ml”, and the opening date is “2013/02/15”. 11 o'clock ”and the expiration date is“ 13 o'clock 2013/02/15 ”.

Here, for convenience of explanation, the case where the prescription amount is equal to or less than the predetermined amount of the ampule 10A and the ampule 10A used is one will be described as an example. On the other hand, when the prescription amount exceeds the predetermined amount of the ampule 10A, a plurality of the ampules 10A are used, and as a result, the medicine remains in one ampule 10A. For example, when the prescription amount of the preparation data Rp1 is “30 ml”, two ampoules 10A are loaded in the container 101. At this time, the first control unit 400 determines that the second ampule 10A has a drug of “10 ml” based on the difference between “40 ml” which is the total amount of the two ampules 10A and “30 ml” of the prescription amount. Judged to remain.

Next, the first control unit 400 includes, as a prescription drug, the same kind of drug as the remaining drug of the drug name “5-FU injection 1000 mg” indicated in the remaining drug information in the preparation data Rp2 to Rp4. If the mixed injection process is performed on the preparation data Rp3 and Rp4, it is determined that the remaining drug can be used.

Then, as shown in FIG. 22C, the first control unit 400 rearranges the preparation data Rp3 and Rp4 among the preparation data Rp2 to Rp4 above the preparation data Rp2, and the prescription selection screen. M1 (see FIG. 20) is preferentially displayed. In addition, as shown in FIG. 22 (C), the first control unit 400 displays “O” on the remaining drug presence / absence display unit D21 (see FIG. 20) on the prescription selection screen M1, thereby preparing the preparation. It is displayed that the remaining drug can be used for data Rp3 and Rp4. Thereby, the user recognizes that the remaining medicine can be used by making the preparation data Rp3 and Rp4 displayed at the top in the prescription selection screen M1 the target of the next mixed injection process. be able to. Note that, as shown in FIG. 22C, for the preparation data Rp2 in which the type of drug different from the remaining drug is a prescription drug, “O” is not displayed in the remaining drug presence / absence display portion D21. It indicates that the remaining drug cannot be used.

For example, in the preparation data Rp3, the prescription amount of the ampule 10A containing the medicine whose preparation name is “5-FU injection 1000 mg”, the dispensed amount is “25 ml”, and the medicine name “5-FU injection 1000 mg” is accommodated. Is shown to be “20 ml”. In the mixed injection process for the preparation data Rp3, two ampoules 10A are required. However, if “5 ml” of the drug “5-FU injection 1000 mg” remains as the remaining drug and the remaining drug can be used, in the mixed injection process for the preparation data Rp3, Only the ampule 10A needs to be newly loaded.

On the other hand, in the preparation data Rp4, the predetermined amount of the ampoule 10A in which the medicine name to be prepared is “5-FU injection 1000 mg”, the dispensed amount is “5 ml”, and the medicine name “5-FU injection 1000 mg” is accommodated. Is shown to be “20 ml”. In the mixed injection process for the preparation data Rp4, one ampoule 10A is required. However, if “5 ml” of the drug “5-FU injection 1000 mg” remains as the remaining drug and the remaining drug can be used, the ampoule 10A is used in the mixed injection process for the preparation data Rp4. There is no need to load a new one. In view of this, it is also conceivable as another embodiment that the first control unit 400 preferentially displays the preparation data, that is, the preparation data Rp4, in which the amount of the remaining medicine is sufficient to be dispensed.

Meanwhile, as shown in FIG. 22D, the first control unit 400 only displays the preparation data Rp3 and Rp4 in order to preferentially display the preparation data Rp3 and Rp4 among the preparation data Rp2 to Rp4. Can be displayed on the prescription selection screen M1. Further, as shown in FIG. 22 (E), the first control unit 400, when a prescription date for a patient is set in advance for the preparation data Rp3 and Rp4, that is, the earlier of the prescription date, that is, the preparation It is also conceivable that the data Rp4 is preferentially displayed at the top.

In addition, when there are a plurality of types of drugs accompanied by a plurality of mixed injection processes in one preparation data, the first control unit 400 determines the presence or absence of the remaining drugs in each of the mixed injection processes, and at least the remaining drugs It is conceivable to preferentially display the preparation data including one kind of medicine as the prescription medicine. In addition, when there are a plurality of types of the remaining drugs, the first control unit 400 may display preparation data having a large number of drugs of the same type as the remaining drugs included as prescription drugs at the top.

[Another Operation Example of the Mixed Injection Device 1] FIG. 23 is a diagram for explaining another actual operation example when the mixed injection management process and the mixed injection control process are executed by the mixed injection control apparatus 100. It is. FIG. 23A shows an example of preparation data, FIG. 23B shows an example of remaining medicine information, and FIG. 23C shows a display example of a part of the prescription display part D2. Note that the information shown in FIG. 23 omits items of information that are less relevant to the present case for convenience of explanation.

Here, as shown in FIG. 23A, a case is considered where preparation data Rp11 to Rp15 are input to the first control unit 400 as selection candidates for the dispensing data to be subjected to the mixed injection process. For example, in the preparation data Rp11, the name of the drug to be prepared is “1 g for Gemzar (registered trademark) injection”, and the payout amount is “25 m”.
l ”, the solvent is“ 100 ml of physiological saline ”, and the amount of the solvent is“ 30 ml ”. That is, in the preparation data Rp11, the components of the mixed drug generated in the vial bottle 10B are the drug “1 g for Gemzar injection” and the solvent “100 ml of physiological saline”. Similarly, in the preparation data Rp12, the name of the drug to be prepared is “2 mg for mitomycin (registered trademark) injection”, the amount to be dispensed is “5 ml”, the solvent is “100 ml of physiological saline”, and the amount of the solvent is “5 ml”. In the preparation data Rp15, the name of the drug to be prepared is “1 g for Gemzar injection”, the amount to be dispensed is “25 ml”, the solvent is “glucose injection 5% 100 ml”, and the amount of the solvent is “30 ml”.

Then, when the preparation data Rp11 is selected as the target of the mixed injection process in the first control unit 400, the first control unit 400 determines whether or not the mixed medicine remains in the vial bottle 10B. To do. Specifically, the first control unit 400 determines whether or not the mixed medicine remains in the vial 10B according to the difference between the solvent amount and the dispensed amount. That is, in the mixed injection process, when a mixed medicine is generated in the medicine container 10, the first control unit 400 stores the amount of the mixed medicine generated in the medicine container 10 in the medicine container 10. To be taken as the prescribed amount of drug. Then, when the first control unit 400 determines that the mixed drug of the drug “Gemzar injection 1 g” and the solvent “100 ml of physiological saline” remains, this is indicated as the remaining drug information (see FIG. 23B). The data is stored in the data storage unit 404. In the remaining drug information shown in FIG. 23B, only “5 ml” of the mixed drug obtained by mixing “30 ml” of the solvent “physiological saline 100 ml” with the drug name “Gemzar injection 1 g” remains in the vial bottle 10B. The effect is shown.

In this case, the first control unit 400 includes the same components as the mixed drug of the drug “Gemzar injection 1 g” and the solvent “physiological saline 100 ml” indicated in the residual drug information in the preparation data Rp12 to Rp15. If the mixed injection process is performed on the preparation data Rp14 including a drug in a mixture ratio as a prescription drug, it is determined that the remaining drug can be used. In addition, since the mixing ratio of the mixed drug is determined according to the amount of components included in the drug name and the solvent amount of the solvent, the first control unit 400 is configured when the drug name and the solvent amount are the same. It can be determined that the mixing ratio of the mixed drugs is the same.

Then, as shown in FIG. 23C, the first control unit 400 rearranges the preparation data Rp14 among the preparation data Rp12 to Rp15 to be higher than the preparation data Rp12 and Rp13, so that the prescription selection screen is displayed. M1 is preferentially displayed. Further, as shown in FIG. 23 (C), the first control unit 400 displays “O” on the remaining drug presence / absence display unit D21 (see FIG. 20) on the prescription selection screen M1, thereby preparing the preparation. For data Rp14, it is displayed that the remaining drug can be used. Thereby, the user recognizes that the remaining drug can be used by setting the preparation data Rp14 displayed at the top in the prescription selection screen M1 as the target of the next mixed injection process. it can.

Note that, as shown in FIG. 23C, for the preparation data Rp12 in which a different type of drug from the remaining drug is a prescription drug, “O” is not displayed in the remaining drug presence / absence display portion D21. It indicates that the remaining drug cannot be used. In addition, as shown in FIG. 23C, for the preparation data Rp13 having a solvent amount different from that of the remaining drug, the remaining drug is used by not displaying “O” in the remaining drug presence / absence display portion D21. It is shown that it cannot be done. Further, as shown in FIG. 23C, for the preparation data Rp15 having a solvent different from that of the remaining drug, the remaining drug is used by not displaying “O” in the remaining drug presence / absence display portion D21. It is shown that it cannot be done.

By the way, strictly speaking, in the mixed medicine, the volume of the mixed medicine increases by the mass of the medicine by the amount of the medicine and the solvent, and the amount of the mixed medicine increases. Therefore, it is conceivable as another embodiment that the first control unit 400 has a function of managing the remaining medicine in consideration of the mass of the medicine. In this case, the first control unit 400 performs a first operation mode in which the mass of the medicine is taken into consideration and a second operation mode in which the mass of the medicine is not taken into account according to a user operation of the operation unit 405 Can be switched. In this case, the data storage unit 404 of the first control unit 400 stores, for example, the mass per unit volume for each drug, the volume per unit mass for each drug, or the volume for each drug name in the drug master. Has been. For example, it is conceivable that a volume corresponding to the drug name “1 g for Gemzar injection” is stored in the drug master. The first controller 400 may obtain the volume of the medicine based on the medicine master and derive the actual capacity of the mixed medicine.

[Other Functions Provided by Mixed Injection Device 1] Hereinafter, other functions provided by the mixed injection device 1 will be described. The function is implemented by executing various processes by the first control unit 400 or the second control unit 500 in the mixed injection management device 100.

[Insufficient amount display function] The first control unit 400 runs short of the medicine container 10 based on the amount of medicine dispensed based on the preparation data and the remaining amount of the remaining medicine stored in the data storage unit 404. It is conceivable to have a deficient amount display function for displaying the number. Here, the first control unit 400 when executing such display processing corresponds to the deficient amount display means.

Specifically, the first controller 400 determines whether or not only the remaining drug is sufficient when the drug indicated by the preparation data is injected into the infusion bag 12 using the remaining drug. When the drug is insufficient, the necessary number of the drug containers 10 is displayed. On the other hand, the first control unit 400 displays that it is not necessary to load the drug container 10 when the remaining drug is sufficient. According to such a configuration, when the user uses the remaining medicine, the user can easily grasp whether or not the medicine container 10 needs to be loaded and the number thereof, so that when using the remaining medicine, Therefore, it is not necessary to consider the number of the drug containers 10 that are insufficient.

[Return Processing Function] In addition, the second controller 500 uses the unused medicine container 10 loaded according to the amount of medicine dispensed based on the preparation data after the remaining medicine is used. It is conceivable to have a return processing function for returning the medicine container 10 from a predetermined return port. The said 2nd control part 500 when performing the return process which concerns here corresponds to a return process means. For example, the return port is an opening communicating with the medicine loading unit 200 side. With such a configuration, since the surplus medicine container 10 is automatically returned, the user is always aware of the number of medicine containers 10 to be loaded when using the remaining medicine. The normal operation of determining and loading the necessary number of drug containers 10 according to the preparation data can be performed.
