Description

  The present invention relates to a co-infusion apparatus that performs a co-infusion process for injecting a medicine such as an anticancer drug contained in a medicine container into an infusion container.

  There is known a co-infusion apparatus for performing a co-infusion process in which a medicine such as an anticancer drug contained in a drug container such as an ampule or a vial is sucked with a syringe and the medicine is injected into an infusion container containing the infusion solution. (For example, refer to Patent Document 1).

JP 2012-250016 A

  By the way, in addition to the co-infusion process in the co-infusion apparatus, an injection operation for injecting other chemicals such as an antiemetic into the infusion container may be required as a preliminary operation. In addition, when the amount of liquid in the infusion container increases or decreases as a result of the co-infusion process in the co-infusion apparatus, in addition to the co-infusion process, a withdrawal operation for extracting the infusion solution from the infusion container or a replenishment operation for replenishing the infusion solution to the infusion container in advance It may be necessary as work.

  The objective of this invention is providing the mixed injection apparatus which can suppress the implementation omission of the preliminary work required separately from the mixed injection process performed with a mixed injection apparatus.

  The co-infusion apparatus according to the present invention separates the co-infusion process from the co-infusion control unit that performs the co-infusion process for aspirating the medicine from the medicine container with the syringe based on the preparation data and injecting the medicine from the syringe into the infusion container. And a notification processing unit capable of notifying a predetermined message when prior work is required before execution of the mixed injection process. Thereby, it becomes possible to suppress omission of the preliminary work required separately from the mixed injection process performed by the mixed injection apparatus.

  Specifically, the pre-operation includes at least one of a replenishment operation of the infusion solution into the infusion container, an extraction operation of the infusion solution from the infusion container, and an operation of injecting another medicine into the infusion container.

  For example, when the medicine is a powder medicine, in the mixed injection process, a dissolving step is performed in which the infusion is extracted from the infusion container with the syringe and the infusion is injected from the syringe into the medicine container. In the mixed injection process, an injection process is also performed in which the medicine is sucked from the medicine container with the syringe and the medicine is injected from the syringe into the infusion container. Here, when the amount of liquid injected into the infusion container in the infusion step is smaller than the amount of infusion extracted from the infusion container in the dissolution step, the amount of liquid in the infusion container is stored in the infusion container. It becomes less than the prescribed amount defined as the amount of infusion contained. In this case, when the infusion of the infusion container is infused to a patient, the infusion time is shorter than when the prescribed amount is administered. Therefore, it is desirable to perform the replenishment operation of replenishing the infusion container with a predetermined amount of infusion before executing the mixed injection process.

  Further, when the drug is a drug solution, in the mixed injection process, when the drug is sucked from the drug container with the syringe and injected into the infusion container, the amount of liquid in the infusion container is accommodated in the infusion container. It exceeds the prescribed amount set as the infusion volume. In this case, when the infusion of the infusion container is administered to the patient by infusion, the infusion time becomes longer than when the prescribed amount is administered. For this reason, it is desirable to perform a sampling operation for extracting a predetermined amount of infusion from the infusion container before the mixed injection process is performed.

  In addition, other drugs such as antiemetics that are originally taken separately from the drugs such as anticancer drugs that are originally injected into the infusion container in the mixed injection process may be pre-injected into the infusion container. In some cases, an injection operation for injecting the other medicine into the infusion container before the mixed injection process is required.

  Here, it is conceivable that the notification processing unit determines that the preliminary work is necessary when the amount of liquid in the infusion container changes as a result of the mixed injection process based on the preparation data. Specifically, the mixed injection control unit, when the drug is a powder medicine, in the mixed injection process, withdrawing the infusion from the infusion container with the syringe and injecting the infusion into the medicine container from the syringe; It is conceivable to perform an injection step of sucking the medicine from the medicine container with the syringe and injecting the medicine from the syringe into the infusion container. In this case, the notification processing unit determines whether or not there is a change in the liquid amount based on the difference between the infusion volume extracted from the infusion container in the dissolution step and the liquid amount injected into the infusion container in the injection step. It is possible to do. In particular, the notification processing unit may determine that the amount of liquid in the infusion container changes when the amount of change in the amount of liquid is equal to or greater than a predetermined threshold. Thereby, when the amount of change in the amount of liquid in the infusion container is small, an operation that does not require the prior work is also possible.

  And it is possible that the said alerting | reporting process part alert | reports the message to the effect of the said replenishment operation | work, when the liquid quantity in the said infusion container reduces as a result of the said mixed injection process based on the said preparation data. Further, it is conceivable that the notification processing unit notifies a message indicating that the sampling operation is required when the amount of liquid in the infusion container increases as a result of the mixed injection process based on the preparation data. Further, when the preparation processing data determines that the notification processing unit needs to inject another medicine different from the medicine injected into the infusion container with the mixed injection device into the infusion container. It is conceivable that a message indicating that the injection operation is required is notified.

  By the way, it is also conceivable that the notification processing unit determines that the amount of liquid in the infusion container increases when the medicine is a chemical solution. In particular, it is conceivable that the notification processing unit determines that the amount of liquid in the infusion container increases when the amount of the chemical solution is equal to or greater than a predetermined threshold. Thereby, when the amount of change in the amount of liquid in the infusion container is small, an operation that does not require the prior work is also possible.

Furthermore, it is conceivable that the notification processing unit displays an image for guiding the needle stick position to the stopper of the infusion container when the message is notified. Thereby, when the user performs the preliminary work, the needle stick position to the stopper can be easily grasped, and the needle stick position in the preliminary work and the needle stick position in the mixed injection process in the mixed injection device. Duplication can be prevented. The present invention provides a mixed injection control unit that performs a mixed injection process for aspirating a drug from a drug container with a syringe based on preparation data and injecting the drug from the syringe into an infusion container, and the mixed injection separately from the mixed injection process. A notification processing unit capable of notifying a predetermined message when a pre-operation is necessary before the processing is performed, and the notification processing unit notifies the message to the stopper of the infusion container when the message is notified It may be a co-infusion apparatus that displays an image for guiding the needle stick position.

  Specifically, the mixed injection control unit is for puncturing the needle of the syringe in the other region by detecting another region except for a predetermined specific puncture region on the upper surface of the stopper of the infusion container, It is conceivable that the image is an image that guides an area excluding a predetermined output puncture area in the specific puncture area as the needle puncture position.

  By the way, when the said message is alert | reported, it is possible that the said mixed injection process does not start until the confirmation operation with respect to the said message is received. Thereby, it is suppressed that the mixed injection process is started without performing the preliminary work.

Furthermore, it is conceivable that the mixed injection control unit can execute a replenishment step of replenishing the infusion container with the infusion when the amount of liquid in the infusion container decreases. Similarly, it is also conceivable that the mixed injection control unit executes an extraction step of extracting the infusion from the infusion container when the amount of liquid in the infusion container increases. That is, it is conceivable that the preliminary work is automatically executed by the mixed injection device instead of the user. The present invention includes a mixed injection control unit that performs a mixed injection process for aspirating a drug from a drug container with a syringe based on preparation data and injecting the drug from the syringe into an infusion container, and the mixed injection control unit includes the A mixed injection device capable of performing a replenishment step of replenishing the infusion container with the infusion when the amount of liquid in the infusion container is reduced by a pre-operation required before the execution of the infusion processing separately from the infusion processing. Also good. Further, the present invention comprises a mixed injection control unit that performs a mixed injection process for aspirating the drug from the drug container with the syringe based on the preparation data and injecting the drug from the syringe into the infusion container, and the mixed injection control unit includes the In addition to the mixed injection process, even when the amount of liquid in the infusion container increases due to the pre-work required before the mixed injection process, the mixed injection apparatus can execute the extraction step of extracting the infusion from the infusion container. Good.

In addition, the mixed injection device can arbitrarily reserve execution of the mixed injection processing based on one or a plurality of the preparation data, and the mixed injection processing based on the preparation data reserved by the reservation setting processing unit It is conceivable to include a reservation execution processing unit capable of executing the mixed injection process when the execution time of the first time arrives. Accordingly, by reserving the execution of the mixed injection processing of the preparation data, the mixed injection processing can be executed at a predetermined execution time such as midnight or a holiday, for example. The present invention includes a mixed injection control unit that performs a mixed injection process for aspirating a drug from a drug container with a syringe based on the preparation data and injecting the drug from the syringe into an infusion container, and one or a plurality of the prepared data. A reservation setting processing unit capable of arbitrarily reserving execution of the mixed injection processing based on, and the mixed injection processing can be executed when it is time to execute the mixed injection processing based on the preparation data reserved by the reservation setting processing unit A co-infusion apparatus including a reservation execution processing unit may be used.

Thereafter, the second control unit 500 raises the equipment placement unit 102 of the tray 101 by the tray lifting / lowering unit 112 of the tray transport unit 110 and exposes it to the mixed injection processing chamber 104.

  Next, the second control unit 500 photographs the equipment placing unit 102 with the tray confirmation camera 41. Then, the second control unit 500 performs the position and orientation of the equipment such as the ampule 10A and the syringe 11 placed on the equipment placement section 102 by image recognition processing based on the image captured by the tray confirmation camera 41. To figure out. In particular, every time the ampule 10A or the syringe 11 is taken out from the device mounting unit 102, the second control unit 500 captures the device mounting unit 102 with the tray confirmation camera 41, and the latest from the captured image. The position and direction of the ampule 10A and the syringe 11 are grasped.

  Subsequently, the second controller 500 uses the first robot arm 21 to place the syringe 11 placed on the device placement unit 102 exposed in the mixed injection processing chamber 104 on the placement shelf 33. Temporary placement. Further, the second control unit 500 sets the ampoule 10 </ b> A placed on the equipment placing unit 102 to the medicine reading unit 34 by the first robot arm 21. Then, the second control unit 500 reads information such as the type of medicine stored in the ampoule 10 </ b> A by the medicine reading unit 34.

  In addition, the second control unit 500 sets the first injection needle 11c to the injection needle attaching / detaching device 43 and the second injection needle 11c to the placement shelf 33 by the first robot arm 21. Temporary placement. Here, the first injection needle 11c is an injection needle without a syringe filter, and the second injection needle 11c is an injection needle with a syringe filter. Note that a cap 11 d is attached to the injection needle 11 c placed on the device placement section 102, and the cap 11 d is attached / detached by the injection needle attaching / detaching device 43. It is also conceivable that the injection needle 11c is set on the tray 101 in a state where it is mounted on the syringe 11a of the syringe 11. In this case, the step of setting the injection needle 11c in the syringe 11 is omitted.

  When the second control unit 500 takes out all the devices on the device placing unit 102, the tray placing unit 102 is lowered by the tray lifting / lowering unit 112 of the tray transporting unit 110, thereby the tray 101. Return to. The second control unit 500 confirms whether or not all the devices on the device mounting unit 102 have been taken out by an image recognition process based on a photographed image by the tray confirmation camera 41.

  Thereafter, the second control unit 500 closes the shutter 111 and causes the tray transport unit 110 to transport the tray 101 to the tray transport termination unit 110a. Next, the second control unit 500 sets the mixed injection port of the infusion bag 12 held by the infusion bag holding unit 103 of the tray 101 by the bag elevating unit 113 of the tray transport unit 110 to the mixed injection processing chamber. It is located in the mixed injection communication port 37 formed in 104.

  Then, the second control unit 500 moves the ampoule 10 </ b> A set in the medicine reading unit 34 to the placement shelf 33 by the second robot arm 22. Next, the second control unit 500 takes out the syringe 11 from the placement shelf 33 by the first robot arm 21 and sets it on the second robot arm 22. Subsequently, the second controller 500 causes the second robot arm 22 to move the syringe 11 to the syringe needle attaching / detaching device 43 to set the syringe needle 11c in the syringe 11. Thereafter, the second controller 500 causes the second robot arm 22 to move the syringe 11 to the needle bend detector 36 to detect whether the injection needle 11c is bent. It is also conceivable that the injection needle 11c is set on the tray 101 while being mounted on the syringe 11. In this case, the step of setting the injection needle 11c in the syringe 11 is omitted.

  Next, the second control unit 500 takes out the ampoule 10A from the placement shelf 33 using the first robot arm 21 and folds the head of the ampoule 10A using the ampoule cutter 31. Then, the second control unit 500 causes the ampule 10A and the syringe 11 to approach each other by the first robot arm 21 and the second robot arm 22, and moves the injection needle 11c of the syringe 11 to the ampule 10A. Insert inside. Thereafter, the second control unit 500 operates the plunger 11b with the second robot arm 22 and sucks the amount of medicine predetermined by the preparation data from the ampoule 10A with the syringe 11.

  At this time, the first robot arm 21 and the second robot arm 22 gradually tilt the posture of the ampoule 10A and the syringe 11. For example, in the state where the mouth of the ampoule 10A is directed vertically upward and the injection needle 11c of the syringe 11 is directed vertically downward, a certain amount of medicine is sucked from the ampoule 10A, and then the ampoule 10A is A state in which the medicine is moved to the side of the mouth (neck) by tilting about 10 degrees with respect to the direction is formed. This makes it possible to suck up the medicine without leaving as much as possible without putting the tip of the injection needle 11c of the syringe 11 on the bottom of the ampoule 10A.

  Thereafter, the second controller 500 controls one or both of the first robot arm 21 and the second robot arm 22 to suck the ampule 10A and the medicine after the medicine is sucked. In this state, the syringe 11 is moved within the imaging range of the syringe confirmation camera 42. The second control unit 500 captures the ampule 10A and the syringe 11 at a time using the syringe confirmation camera 42, and records the captured image in the data storage unit 504 as an inspection image. For example, the syringe confirmation camera 42 captures the predetermined photographing range. On the other hand, the syringe control camera 42 so that the ampule 10A and the syringe 11 after the second controller 500 is moved by the first robot arm 21 and the second robot arm 22 can be photographed at a time. It is also conceivable that the shooting range can be changed.

  Next, the second control unit 500 replaces the injection needle 11 c of the syringe 11 with the first robot arm 21 and the second robot arm 22. Specifically, the second controller 500 uses the second robot arm 22 to move the syringe 11 to the needle bend detector 36 and detects whether the injection needle 11c is bent. The second robot arm 22 moves the syringe 11 to the injection needle attaching / detaching device 43 to attach the cap 11d to the injection needle 11c. Then, the second control unit 500 rotates the cap 11 d by the injection needle attaching / detaching device 43 to remove the injection needle 11 c from the syringe 11. The removal of the injection needle 11c may be performed by rotating the cap 11d by the first robot arm 21 and the second robot arm 22.

  The second controller 500 opens the dust cover 132a, drops the injection needle 11c held by the injection needle attaching / detaching device 43 by the first robot arm 21 into the dust storage chamber 13a, and discards it. To do. Thereafter, the second control unit 500 causes the first robot arm 21 to set the injection needle 11c with the syringe filter from the placement shelf 33 to the injection needle attaching / detaching device 43. Then, the second control unit 500 moves the syringe 11 to the injection needle attaching / detaching device 43 by the second robot arm 22 and attaches the injection needle 11 c to the syringe 11. Also in this case, the second control unit 500 moves the syringe 11 to the needle bending detection unit 36 by the second robot arm 22 and detects the presence or absence of the bending of the injection needle 11c. Thus, in the co-infusion apparatus 1, the injection needle 11c is replaced when the drug is sucked from the ampule 10A and when the infusion is injected into the infusion bag 12, and the fragments of the ampule 10A are replaced with the infusion bag. 12 is prevented.

  Then, the second control unit 500 punctures the injection needle 11c of the syringe 11 into the rubber stopper of the mixed injection port of the infusion bag 12 conveyed to the tray conveyance termination unit 110a by the second robot arm 22. Then, the mixed medicine in the syringe 11 is injected into the infusion bag 12. On the other hand, the second control unit 500 opens the dust lid 132a and drops the ampoule 10A into the dust storage chamber 13a by the first robot arm 21 and discards it. The second controller 500 moves the syringe 11 to the injection needle attaching / detaching device 43 by the second robot arm 22 and attaches the cap 11d to the injection needle 11c of the syringe 11. The syringe 11 is dropped into the garbage storage chamber 13a and discarded.

  Thereafter, the second control unit 500 reads various images taken by the syringe confirmation camera 42 and the like from the data storage unit 504 and causes the touch panel monitor 14 to display them. As a result, the user can check whether or not the mixed injection process is appropriate while looking at the touch panel monitor 14.

[Mixed injection process using vial 10B]
Subsequently, when the medicine stored in the vial bottle 10B is a medicine such as a powder medicine that needs to be dissolved, the basics of the mixed injection process when the medicine is mixed with the infusion solution and then injected into the infusion bag 12 are as follows. The operation will be described.

  When the tray 101 is supplied to the tray transport unit 110, the second control unit 500 reads the identification information of the tray 101 from the IC tag 101b of the tray 101 by the IC reader 101c. Then, the second control unit 500 opens the shutter 111 when the identification information of the tray 101 matches the identification information previously associated with the preparation data of the mixed injection process. Thereafter, the second control unit 500 raises the equipment placement unit 102 of the tray 101 by the tray lifting / lowering unit 112 of the tray transport unit 110 and exposes it to the mixed injection processing chamber 104.

  Next, the second control unit 500 photographs the equipment placing unit 102 with the tray confirmation camera 41. Then, the second controller 500 determines the position of the equipment such as the vial 10B and the syringe 11 placed on the equipment placing section 102 by the image recognition process based on the image taken by the tray confirmation camera 41. Know the direction. In particular, each time the second control unit 500 takes out the vial 10B or the syringe 11 from the instrument mounting unit 102, the second control unit 500 captures the instrument mounting unit 102 with the tray confirmation camera 41, and from the captured image. The latest position and orientation of the vial 10B and the syringe 11 are grasped.

  Subsequently, the second controller 500 uses the first robot arm 21 to place the syringe 11 placed on the device placement unit 102 exposed in the mixed injection processing chamber 104 on the placement shelf 33. Temporary placement. In addition, the second control unit 500 sets the vial 10 </ b> B placed on the device placement unit 102 to the medicine reading unit 34 by the first robot arm 21. Then, the second control unit 500 reads information such as the type of medicine stored in the vial bottle 10 </ b> B by the medicine reading unit 34.

  Next, when the second control unit 500 takes out all the devices on the device placing unit 102, the tray placing unit 102 is lowered by the tray lifting and lowering unit 112 of the tray transporting unit 110, and the tray. Return to 101. The second control unit 500 confirms whether or not all the devices on the device mounting unit 102 have been taken out by an image recognition process based on a photographed image by the tray confirmation camera 41.

  Thereafter, the second control unit 500 closes the shutter 111 and causes the tray transport unit 110 to transport the tray 101 to the tray transport termination unit 110a. Next, the second control unit 500 sets the mixed injection port of the infusion bag 12 held by the infusion bag holding unit 103 of the tray 101 by the bag elevating unit 113 of the tray transport unit 110 to the mixed injection processing chamber. It is located in the mixed injection communication port 37 formed in 104.

  Then, the second control unit 500 moves the vial 10 </ b> B set in the medicine reading unit 34 to the placement shelf 33 by the second robot arm 22. On the other hand, in parallel with this movement process, the second control unit 500 uses the first robot arm 21 to attach and detach the injection needle 11c of the syringe 11 placed on the device placement unit 102. Set in the device 43.

  Next, the second control unit 500 takes out the syringe 11 from the placement shelf 33 by the first robot arm 21 and sets it on the second robot arm 22. Subsequently, the second controller 500 causes the second robot arm 22 to move the syringe 11 to the syringe needle attaching / detaching device 43 to set the syringe needle 11c in the syringe 11. Thereafter, the second controller 500 causes the second robot arm 22 to move the syringe 11 to the needle bend detector 36 to detect whether the injection needle 11c is bent. It is also conceivable that the injection needle 11c is set on the tray 101 in a state where the injection needle 11c is attached to the syringe 11a of the syringe 11. In this case, the step of setting the injection needle 11c in the syringe 11 is omitted.

  Subsequently, the second control unit 500 punctures the injection needle 11c of the syringe 11 into the rubber stopper of the mixed injection port of the infusion bag 12 conveyed to the tray conveyance termination unit 110a by the second robot arm 22. Then, the infusion solution of the dissolution amount indicated by the preparation data is aspirated from the infusion bag 12. On the other hand, the second control unit 500 takes out the vial 10 </ b> B placed on the placement shelf 33 by the first robot arm 21.

  Then, the second controller 500 causes the vial 10B and the syringe 11 to approach each other by the first robot arm 21 and the second robot arm 22, and moves the injection needle 11c of the syringe 11 to the The vial bottle 10B is punctured. Thereafter, the second controller 500 operates the plunger 11b with the second robot arm 22 to inject the infusion in the syringe 11 into the vial 10B. Thus, when the medicine is a powder medicine, in the mixed injection process, a dissolving step is performed in which the infusion is extracted from the infusion bag 12 by the syringe 11 and the infusion is injected from the syringe 11 into the vial bottle 10B. Is done. Thereby, the medicine in the vial bottle 10B is dissolved by the infusion solution. 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 second controller 500 uses the first robot arm 21 to set the vial bottle 10B 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 second control unit 500 takes out the vial 10B from the stirring device 32 by the first robot arm 21.

  Then, the second control unit 500 causes the vial 10B and the syringe 11 to approach each other by the first robot arm 21 and the robot arm 22 so that the injection needle 11c of the syringe 11 is moved to the vial. Puncture 10B. Thereafter, the second controller 500 operates the plunger 11b with the second robot arm 22 to suck the mixed drug in the vial bottle 10B with the syringe 11. At this time, the posture of the syringe 11 and the vial bottle 10B is such that the mouth of the vial bottle 10B is directed vertically downward and the injection needle 11c of the syringe 11 is directed vertically upward.

  Thereafter, the second control unit 500 controls one or both of the first robot arm 21 and the second robot arm 22 to remove the vial 10B and the medicine after the medicine is sucked. The syringe 11 in the sucked state is moved within the photographing range of the syringe confirmation camera 42. The second control unit 500 captures the vial 10B and the syringe 11 at a time using the syringe confirmation camera 42, and records the captured images in the data storage unit 504 as inspection images. For example, the syringe confirmation camera 42 captures the predetermined photographing range. On the other hand, the syringe confirmation camera is configured so that the vial 10B and the syringe 11 can be photographed at a time after the second controller 500 is moved by the first robot arm 21 and the second robot arm 22. It is also conceivable that the 42 shooting ranges can be changed.

  Then, the second control unit 500 punctures the injection needle 11c of the syringe 11 into the rubber stopper of the mixed injection port of the infusion bag 12 conveyed to the tray conveyance termination unit 110a by the second robot arm 22. Then, the mixed medicine in the syringe 11 is injected into the infusion bag 12. Thus, in the mixed injection process, an injection process is performed in which the medicine is sucked from the vial bottle 10B by the syringe 11 and the medicine is injected from the syringe 11 into the infusion bag 12.

  On the other hand, the second controller 500 opens the dust lid 132a and drops the vial 10B into the dust storage chamber 13a by the first robot arm 21 and discards it. The second controller 500 moves the syringe 11 to the injection needle attaching / detaching device 43 by the second robot arm 22 and attaches the cap 11d to the injection needle 11c of the syringe 11. The syringe 11 is dropped into the garbage storage chamber 13a and discarded.

  Thereafter, the second control unit 500 reads various images taken by the syringe confirmation camera 42 and the like from the data storage unit 504 and causes the touch panel monitor 14 to display them. As a result, the user can check whether or not the mixed injection process is appropriate while looking at the touch panel monitor 14.

  In addition, it is also considered that the chemical | medical agent accommodated in the said vial bottle 10B is a chemical | medical agent like a chemical | medical solution which does not need to melt | dissolve. The mixed injection process in this case is performed by dissolving the chemical contained in the vial bottle 10B except that the step of sucking the infusion liquid from the infusion bag 12 and injecting the infusion liquid into the vial bottle 10B is not performed. Since it is the same as the mixed injection process in the case of a necessary medicine such as a powder medicine, the description is omitted.

[Load preparation process]
In the mixed injection device 1, the first control unit 400 prepares for loading to store the drug container 10, the syringe 11, the infusion bag 12, and the like in the tray 101 before the execution of the mixed injection process. A loading preparation process for supporting the above is executed. FIG. 18 is a flowchart showing an example of the loading preparation process.

<Step S1>
First, in step S <b> 1, the first control unit 400 performs a loading preparation start operation for starting a preparatory work for loading chemicals and equipment necessary for the mixed injection processing based on the preparation data to the operation unit 405. It is judged whether it was done. The loading preparation start operation includes an operation of selecting the preparation data to be subjected to the current preparation work from one or more unprocessed preparation data. If it is determined that the loading preparation start operation has been performed (S1: Yes), the process proceeds to step S2. Further, until the loading preparation start operation is performed (S1: No), the process waits at the step S1.

<Step S2>
In step S <b> 2, the first control unit 400 determines whether or not prior work is necessary separately from the mixed injection process based on the preparation data selected in the loading preparation start operation.

  Specifically, the first control unit 400 determines that the preliminary work is necessary when the amount of liquid in the infusion bag 12 changes as a result of the mixed injection process based on the preparation data.

  For example, when the amount of the liquid injected into the infusion bag 12 in the injection step is smaller than the amount of the infusion extracted from the infusion bag 12 in the dissolution step, the amount of liquid in the infusion bag 12 is It becomes less than the prescribed amount defined as the amount of infusion contained in the infusion bag 12. In this case, when the infusion of the infusion bag 12 is infused to the patient, the infusion time is shorter than when the prescribed amount is administered. Therefore, the first control unit 400 is based on the difference (decreasing amount) between the amount of the infusion extracted from the infusion bag 12 in the dissolution step and the amount of the liquid injected into the infusion bag 12 in the injection step. Thus, it is determined that a replenishment operation for replenishing the infusion bag 12 with a predetermined amount of infusion before the mixed injection process is necessary as the preliminary operation. More specifically, the first control unit 400 determines that the amount of liquid in the infusion bag 12 decreases as a result of the mixed injection process when the difference is equal to or greater than a predetermined threshold, and the replenishment operation Is determined to be necessary.

  Further, when the drug is a drug solution, in the mixed injection process, when the drug is sucked from the drug container 10 with the syringe and injected into the infusion bag 12, the amount of liquid in the infusion bag 12 becomes the infusion bag. 12 is greater than the prescribed amount determined as the amount of infusion contained in the fluid. In this case, when the infusion of the infusion bag 12 is administered to the patient by infusion, the infusion time becomes longer than when the prescribed amount is administered. Therefore, the first control unit 400 determines that a sampling operation for extracting a predetermined amount of infusion from the infusion bag 12 is necessary as the preliminary operation before the mixed injection process is performed. More specifically, the first control unit 400 determines that the liquid amount in the infusion bag 12 increases as a result of the mixed injection process when the liquid amount of the medicine is equal to or greater than a predetermined threshold value, It is determined that the extraction work is necessary.

  Further, the first control unit 400 determines in the preparation data that it is necessary to inject another medicine different from the medicine injected into the infusion bag 12 by the mixed injection device into the infusion bag 12. If it is determined that the injection operation is necessary, it is determined that the injection operation is necessary as the preliminary operation. In the present embodiment, the case where the necessity of the replenishment operation, the extraction operation, and the injection operation is determined as the preliminary operation in the step S2 will be described. However, in the present invention, the replenishment operation is performed. The necessity of at least one of the extraction operation and the injection operation may be determined.

<Step S3>
Next, in step S3, the first controller 400 determines whether or not the preliminary work is determined to be necessary in step S2. That is, it is determined whether it is determined that at least one of the replenishment operation, the sampling operation, and the injection operation is necessary. Here, when the preliminary work is necessary (S3: Yes), the process proceeds to step S4. When the preliminary work is not necessary (S3: No), the process proceeds to step S301.

<Step S301>
In step S301, the first control unit 400 causes the display 203 to display a display screen D11 including a message for instructing reading of identification information such as the GS1 data bar of the infusion bag 12, and the process proceeds to step S8. Transition. FIG. 19 is a diagram showing an example of the display screen D11. On the display screen D11 shown in FIG. 19, a message M11 such as “Please read the GS1 data bar of physiological saline (500 mL)” is displayed together with the contents of the preparation data.

  Here, when the identification information of the infusion bag 12 is read by the barcode reader 204 and the collation result with the preparation data matches, the first control unit 400 shifts the process to step S8. In addition, it is possible that the said 1st control part 400 displays an error message, for example, when the collation result with the identification information of the said infusion bag 12 and the said preparation data does not correspond.

<Step S4>
On the other hand, when it is determined that the preliminary work is necessary, in the subsequent step S4, the first control unit 400 needs the preliminary work before executing the mixed injection process separately from the mixed injection process. A predetermined message indicating the effect is notified. Note that the content of the message is not limited to the content described here, as long as it relates to the preliminary work. The said 1st control part 400 when performing the process which concerns here is an example of an alerting | reporting process part. Specifically, the first control unit 400 requires the preliminary work by causing the display 203 to display a display screen D12 including a predetermined message corresponding to the content of the preliminary work. It is possible to notify that there is. Thereby, since it can be made to recognize that the said preliminary work is required when performing the said mixed injection process about the said preparation data, the omission of the said preliminary work is suppressed. The notification is not limited to the display of the message, but may be performed by reproducing a predetermined message voice.

  FIG. 20 is a diagram illustrating an example of the display screen D12 displayed when the content of the preliminary work is the sampling work. In the display screen D12 shown in FIG. 20, the pre-sampling operation is set in advance corresponding to the case where the pre-sampling work is necessary, and “pre-sampling work is present” indicating that the sampling work is required. A message M12 such as “Do you want to start loading?” Is displayed.

  Further, the preliminary work includes the replenishing work and the pouring work in addition to the sampling work. If it is determined in step S2 that the difference is equal to or greater than the threshold value and the replenishment operation is necessary, in step S4, there is a “pre-replenishment operation” indicating that the replenishment operation is required. A message such as "Do you want to start loading?" Further, when it is determined in step S2 that the injection operation is necessary as the preliminary operation, in step S4, “there is a preliminary injection operation indicating that the injection operation is required. "Are you sure?" It should be noted that a common message such as “There is a pre-work. Do you want to start loading?” May be displayed regardless of the content of the pre-work.

<Step S5>
In step S5, as in step S301, the first control unit 400 displays the display screen D11 including the message M11 for instructing reading of identification information such as the GS1 data bar of the infusion bag 12. 203 is displayed. Here, when the identification information of the infusion bag 12 is read by the barcode reader 204 and the collation result with the preparation data matches, the first control unit 400 shifts the process to step S6. In addition, it is possible that the said 1st control part 400 displays an error message, for example, when the collation result with the identification information of the said infusion bag 12 and the said preparation data does not correspond.

<Step S6>
In step S6, the first control unit 400 notifies the details of the preliminary work. Specifically, the first control unit 400 causes the display 203 to display a display screen D13 including a predetermined message corresponding to the content of the preliminary work, thereby displaying the content of the preliminary work. Inform. This allows the user to recognize the contents of the preliminary work when executing the mixed injection process for the preparation data. The notification may be performed by playing a predetermined message voice.

  FIG. 21 is a diagram illustrating an example of the display screen D13 displayed when the content of the preliminary work is the sampling work. In the display screen D13 shown in FIG. 21, together with the contents of the preparation data, a preset “extract a specified amount from the infusion solution” corresponding to the case where the sampling operation is necessary as the preliminary operation. A message M131 such as “Please” is displayed. Further, on the display screen D13, a message M132 such as “please remove 10.0 mL from the infusion” indicating the extraction amount in the extraction operation is also displayed. Thereby, the user can easily grasp the contents of the preliminary work.

  Further, the display screen D13 displays an image P131 and a message M133 for guiding the needle stick position of the syringe when the drug solution is extracted from the infusion bag 12 in the extraction operation. Specifically, in the example shown on the display screen D13, along with the message M133 such as “Put the extraction needle into the place indicated by the red circle at the needle insertion position” and the like on the upper surface of the rubber stopper of the infusion bag 12. The image P131 in which the needle stick position is indicated by a red circle mark P132 is displayed. For example, the mark P132 is not directly written on the upper surface of the rubber stopper of the infusion bag 12, but the image of the upper surface of the rubber stopper of the infusion bag 12 displayed on the display screen D13 indicates the position of the needle stick position. It is an image combined as an index. Note that a guide image obtained by combining the image of the upper surface of the rubber stopper of the infusion bag 12 and the image of the mark P132 is stored in advance in the data storage unit 404 in association with the type of the infusion bag 12. Yes. The upper surface of the rubber stopper of the infusion bag 12 includes an output puncture region and an input puncture region as predetermined specific puncture regions. In the puncture area for output, the characters “OUT” indicating that the infusion solution in the infusion bag 12 is used when administering the infusion solution to a patient, and in the puncture area for input, The characters “IN” indicating that the region is used when injecting a medicine are described. In the image P131, the characters “OUT” and “IN” are also displayed. In the display screen D13, the input puncture area excluding the output puncture area in the specific puncture area is guided by the image P131 as the needle puncture position. Thereby, the user can grasp | ascertain easily the needle stick position which stabs the needle | hook of a syringe by the said prior work. Such guidance of the needle stick position in the preliminary work is performed in the same manner when the replenishment work and the injection work are necessary. In the display screen D13, the display of the mark P132 is omitted, and the message M133 indicates that the input puncture area is used, for example, “Put the extraction needle into the place of IN”. A message may be displayed.

  On the other hand, in the co-infusion apparatus 1, in the co-infusion process, the injection needle 11c of the syringe 11 is punctured in an area other than the needle puncture position guided on the display screen D13 and the output puncture area. . Here, the position and range of the other region are determined in advance for each type of the infusion bag 12, and the data recording unit 404 of the first control unit 400 and the data recording unit 504 of the second control unit 500. It may be stored in In addition, the second control unit 500 notifies the second control unit 500 of the needle puncture position or the other region guided on the display screen D13 or the like, so that the second control unit 500 can perform the other control. It is also conceivable to determine the position and range of the region. Note that it is also possible that the specific puncture area includes a plurality of the input puncture areas, and only a part of the input puncture area is guided as the needle puncture position in the step S6. It is done. In this case, it is also conceivable that other input puncture areas that are not guided as the needle puncture positions are included in the other areas. The second control unit 500 captures the rubber plug of the infusion bag 12 with the needle insertion confirmation camera 44 or the like when the injection needle 11c punctures the rubber plug of the infusion bag 12 in the mixed injection process. Based on the above, the other area excluding the needle stick position is detected. Then, the second controller 500 controls the second robot arm 22 to puncture the injection needle 11c in the other area. Thereby, overlap and proximity of the needle stick positions in the preliminary work and the mixed injection process are prevented. In addition, when the mounting posture of the infusion bag 12 on the tray 101 is predetermined, the second control unit 500 detects the other region excluding the needle stick position based on the mounting posture. Is also possible.

  By the way, when the preliminary work is executed by the user before the mixed injection process is executed, a history that the preliminary work has been properly performed by the first control unit 400 is recorded in the data recording unit 404. May be recorded. For example, a weighing meter connected to the first control unit 400 is provided on the work table 202, and the first control unit 400 displays a result of weighing by the weighing meter while the display screen D13 is displayed. It is conceivable to record as the history. Thereby, for example, the weighing result of the infusion bag 12 after the infusion solution is extracted by the extraction operation or the weighing result of the infusion bag 12 after the infusion solution is replenished by the replenishment operation is left as the history. It becomes possible. Similarly, when the other medicine is injected into the infusion bag 12 in the infusion operation, the weighing result of the infusion bag 12 after the injection can be left as the history. Furthermore, it is also conceivable that the medicine loading unit 200 is provided with an imaging unit such as a digital video camera for photographing the state of the preliminary work, and the state of the preliminary work is recorded in the data recording unit 404 as a history. It is done.

<Step S7>
Next, in step S7, the first control unit 400 waits for a confirmation operation for the preliminary work (S7: No). Specifically, an operation key K131 for accepting the confirmation operation is displayed on the display screen D13, and the first control unit 400 performs the confirmation by operating the operation key K131 using the operation unit 405. Accept the operation.

  And if the said confirmation operation is performed (S7: Yes), a process will transfer to step S7. That is, in the co-infusion apparatus 1, the co-infusion control unit 100 starts the co-infusion processing based on the preparation data until the confirmation operation is performed when the preliminary work is necessary for the preparation data. I won't let you. Therefore, the omission of the preliminary work is more effectively suppressed. When a plurality of the preliminary works are necessary, the processes in steps S6 to S7 are repeatedly executed corresponding to each preliminary work.

<Step S8>
Thereafter, in step S8, the first controller 400 causes the display 203 to display a display screen D14 for guiding the placement of the infusion bag 12 on the tray 101. FIG. 22 is a diagram showing an example of the display screen D14. In the display screen D14 shown in FIG. 22, a message M14 indicating the arrangement method of the infusion bag 12 is displayed together with the contents of the preparation data. And if the operation input to the effect that the arrangement | positioning operation | work of the said infusion bag 12 was completed, the said 1st control part 400 will transfer a process to step S9.

<Step S9>
In step S9, the first controller 400 causes the display 203 to display a display screen D15 including a message for instructing reading of identification information such as the GS1 data bar of the medicine container 10. FIG. 23 is a diagram showing an example of the display screen D15. In the display screen D15 shown in FIG. 23, a message M15 such as “Please read FU1 1000 mg GS1 data bar” is displayed together with the contents of the preparation data.

  Here, when the identification information of the medicine container 10 is read by the barcode reader 204 and the collation result with the preparation data matches, the first control unit 400 shifts the process to step S10. The first control unit 400 displays an error message when the collation result between the identification information of the medicine container 10 and the preparation data does not match.

<Step S10>
In step S <b> 10, the first control unit 400 causes the display 203 to display a display screen D <b> 16 for guiding the placement of the medicine container 10 on the tray 101. FIG. 24 shows an example of the display screen D16. In the display screen D16 shown in FIG. 24, a message M16 indicating the arrangement method of the medicine container 10 is displayed together with the contents of the preparation data. And if the operation input to the effect that the arrangement | positioning operation | work of the said chemical | medical agent container 10 was completed is performed, the said 1st control part 400 will transfer a process to step S11.

<Step S11>
In step S <b> 11, the first controller 400 causes the display 203 to display a display screen D <b> 17 for guiding the placement of the syringe 11 on the tray 101. FIG. 25 is a diagram showing an example of the display screen D17. On the display screen D17 shown in FIG. 25, a message M17 indicating the arrangement method of the syringe 11 is displayed together with the contents of the preparation data. And if the operation input to the effect that the arrangement | positioning operation | work of the said syringe 11 was completed is performed, the said 1st control part 400 will transfer a process to step S12.

<Step S12>
In step S <b> 12, the first control unit 400 causes the display 203 to display a display screen D <b> 18 including a message prompting registration of completion of loading related to the preparation data. FIG. 26 shows an example of the display screen D18. In the display screen D18 shown in FIG. 26, a message M18 for prompting registration of the completion of the loading related to the preparation data to be prepared this time is displayed together with the contents of the preparation data. Here, when an operation input for registration of the completion of loading is performed, the first control unit 400 shifts the processing to step S13.

<Step S13>
In step S13, the first control unit 400 records a part of the preparation data on the electronic paper 101a of the tray 101 and includes a display screen D19 including a message indicating that the preparation data has been registered for completion. Is displayed on the display 203. Thereby, in the co-infusion apparatus 1, the co-infusion process is started when it is detected by a sensor (not shown) that the tray 101 is loaded from the tray insertion port 114.

  FIG. 27 shows an example of the display screen D19. In the display screen D19 shown in FIG. 27, a message M19 indicating that the preparation of the preparation data, which is the preparation object at this time, has been completed is displayed together with the contents of the preparation data. In addition, when an operation input for interrupting loading is performed while the display screen D11 to the display screen D19 are being displayed, the preparation for loading based on the preparation data is stopped.

[Second Embodiment]
As described above, in the co-infusion apparatus 1, the amount of liquid in the infusion bag 12 may change as a result of the co-infusion process. And in the said 1st Embodiment, the case where the preliminary work for adjusting the liquid quantity in the said infusion bag 12 in advance was performed by the pharmacist etc. was demonstrated.

[Infusion volume control processing]
On the other hand, in the present embodiment, the second control unit 500 automatically adjusts the infusion amount in the infusion bag 12 so that the amount of liquid in the infusion bag 12 does not change in the mixed injection process or sampling. The structure which can perform the infusion volume control process including a process is demonstrated. In the following embodiment, the description of the same configuration as that of the first embodiment is omitted. FIG. 28 is a flowchart showing an example of the procedure of the infusion volume control process. For example, the infusion volume control process is executed before the mixed injection process is started. The infusion volume control process may be executed during the mixed injection process or after the mixed injection process.

<Step S21>
First, in step S21, the second control unit 500 determines whether or not the medicine in the medicine container 10 used in the mixed injection process based on the preparation data is a powder medicine. Here, if the said 2nd control part 500 judges that the said chemical | medical agent is a powder medicine (S21: Yes), it will transfer a process to step S22. Further, when the second control unit 500 determines that the medicine is not a powder medicine, that is, the medicine is a chemical liquid (S21: Yes), the process proceeds to step S211.

<Step S22>
In step S <b> 22, the second control unit 500 calculates a difference between the amount of infusion extracted from the infusion bag 12 and the amount of liquid injected into the infusion bag 12 in the mixed injection process. For example, when the amount of liquid to be injected from the drug container 10 into the infusion bag 12 is smaller than the amount of infusion necessary to dissolve the powder medicine in the drug container 10, the inside of the infusion bag 12 Is less than the prescribed amount of liquid contained in the infusion bag 12. Therefore, in the infusion volume control process, the second controller 500 determines the difference between the infusion volume extracted from the infusion bag 12 in the dissolution process and the liquid volume injected into the infusion bag 12 in the infusion process (liquid The presence or absence of a change in the amount of liquid is determined based on the amount of change in amount.

<Step S23>
In step S23, the second controller 500 determines whether or not the difference calculated in step S22 is greater than or equal to a preset threshold value. Thereby, when the difference is small, an operation that does not require the prior work is possible. It is conceivable that the threshold is set at a predetermined ratio with respect to the volume of the infusion bag 12 such as N% of the volume of the infusion bag 12. It is also conceivable that the predetermined range is set to a specific value regardless of the volume of the infusion bag 12.

  If it is determined that the difference is greater than or equal to the threshold (S23: Yes), the process proceeds to step S24. If it is determined that the difference is not greater than or equal to the threshold (S23: No), the process is performed. The infusion volume control process ends. That is, when the difference is less than the threshold value, the replenishment step (S24) for replenishing the infusion of the infusion bag 12 is not performed. Note that the step S23 may be omitted.

<Step S24>
In step S24, the second controller 500 executes a replenishment step of replenishing the infusion bag 12 with an amount of infusion corresponding to the difference calculated in step S22. Specifically, the second control unit 500 controls the first robot arm 21 and the second robot arm 22 in the replenishment step, and is accommodated in a replenishment container previously disposed on the tray 101. The infusion solution is extracted by the syringe 11 and injected into the infusion bag 12. Thereby, even after the mixed injection process is executed, the infusion bag 12 is in a state where a predetermined amount of liquid that is predetermined as the amount of liquid in the infusion bag 12 is stored. Therefore, when the infusion in the infusion bag 12 is administered to a patient by infusion, the time required for the infusion coincides with the time required from the prescribed amount of the infusion bag 12. The second control unit 500 controls the first robot arm 21 and the second robot arm 22, and the replenishment container placed in advance on the placement shelf 33 or the like of the mixed injection processing chamber 104. It is also conceivable to inject the stored infusion solution with the syringe 11 and inject it into the infusion bag 12.

  Here, the replenishing container is a resin infusion container that is opened by twisting a stopper formed on the upper part of the body part. In this case, in the mixed injection device 1, the first robot arm 21 is held in a state where the body portion is gripped by one of the first robot arm 21 and the second robot arm 22 and the plug portion is gripped by the other. The refill container is opened by the relative rotation of the second robot arm 22. Note that the replenishing container may be the vial 10B in which an infusion solution is accommodated, or the other infusion bag 12 disposed in the mixed injection processing chamber 104 as the replenishment container.

<Step S211>
On the other hand, in step S211, the second controller 500 determines whether or not the liquid amount of the medicine injected into the infusion bag 12 is equal to or greater than the threshold value. Thereby, when the amount of liquid of the medicine is small, an operation that does not require the prior work is possible. Note that the threshold value in step S23 may be different from the threshold value in step S211. It is also conceivable that Step S212 described later is executed on the condition that the medicine is a liquid, that is, Step S211 is omitted.

  Here, when it is determined that the liquid amount of the medicine is equal to or greater than the threshold (S211: Yes), the process proceeds to step S212, and when it is determined that the liquid amount of the medicine is not equal to or greater than the threshold (S211). : No), the process ends the infusion volume control process. That is, when the liquid amount of the medicine is less than the threshold value, the extraction step (S212) for extracting the infusion solution from the infusion bag 12 is not executed.

<Step S212>
In step S <b> 212, the second control unit 500 executes an extraction process for extracting from the infusion bag 12 an amount of infusion corresponding to the amount of liquid of the medicine. Thereby, even after the mixed injection process is executed, the infusion bag 12 is in a state where a predetermined amount of liquid that is predetermined as the amount of liquid in the infusion bag 12 is stored. Therefore, when the infusion in the infusion bag 12 is administered to a patient by infusion, the time required for the infusion coincides with the time required from the prescribed amount of the infusion bag 12. Specifically, the second control unit 500 controls the first robot arm 21 and the second robot arm 22 in the extraction step, and extracts the infusion solution in the infusion bag 12 with the syringe 11 and the tray 101. The waste container is poured into a waste container 13a in the waste lid 132a.

  Here, the extraction container is empty or the vial bottle 10B after use. Further, the second control unit 500 controls the first robot arm 21 and the second robot arm 22, and the infusion solution extracted from the infusion bag 12 by the syringe 11 is placed in the pre-installation shelf of the mixed injection processing chamber 104. It is also conceivable to inject into a sampling container previously placed on 33 or the like. Furthermore, after the infusion solution is stored in the extraction container, the second control unit 500 may place the extraction container on the placement shelf 33 as the replenishment container. It is also conceivable that the extraction container is the other infusion bag 12 disposed in the mixed injection processing chamber 104.

  By the way, as described above, in the infusion volume control process, before the tray 101 is inserted into the tray insertion port 114, the extraction container or the replenishing container placed on the tray 101 by the user is stored. It can be used. Therefore, in the co-infusion apparatus 1, the first control unit 400 uses the sampling container or the replenishing container as the contents of the preliminary work in step S6 in the loading preparation process (see FIG. 18). It is conceivable to notify that the tray 101 is placed. For example, when the amount of liquid in the infusion bag 12 increases, a message indicating that the extraction container is placed on the tray 101 is displayed, and when the amount of liquid in the infusion bag 12 decreases, It is conceivable that a message indicating that the replenishment container is placed on the tray 101 is displayed. It is also conceivable that the second control unit 500 can execute the step of injecting the other medicine to be injected in the injection operation into the infusion bag 12 together with the mixed injection process. In this case, it is conceivable that a message indicating that the medicine container 10 corresponding to the other medicine is placed on the tray 101 is displayed in the step S6 in the loading preparation process.

  Further, in step S6, the first control unit 400 displays an operation key for allowing the user to select whether to perform the preliminary work manually or automatically as the content of the preliminary work. Can be considered. In this case, the first control unit 400 records the selection result by the user in the data storage unit 404 as the preparation history of the preparation data. Then, when it is selected that the preliminary work is to be performed manually, the first control unit 400 allows the user to perform the preliminary work as in the display screen D13 shown in FIG. It is conceivable to perform notification for prompting execution. In addition, the first control unit 400 is configured to prompt the user to place the extraction container or the replenishment container on the tray 101 when it is selected that the preliminary operation is automatically performed. It is conceivable to perform notification.

[Other examples of infusion volume control processing]
FIG. 29 is a flowchart showing another example of the infusion volume control process. In the example shown in FIG. 29, in the infusion volume control process, step S201 is executed before the step S21, and the steps S23 and S211 are omitted.

<Step S201>
In step S <b> 201, the second control unit 500 determines whether the extraction container or the replenishment container is placed on the tray 101. Specifically, the second control unit 500 controls the first robot arm 21 in the mixed injection process, and together with the medicine container 10 and the syringe 11 from the tray 101, the extraction container or the replenishment container. In order. Then, the second controller 500 reads the barcode for identifying the extraction container or the replenishment container from the extraction container or the replenishment container using the medicine reading unit 34. Thereafter, the second control unit 500 places the sampling container or the replenishing container on the placement shelf 33. Accordingly, when the medicine reading unit 34 reads the identification information of the extraction container or the replenishment container, the second control unit 500 causes the tray 101 to store the extraction container or the replenishment container. It is possible to determine that it has been placed. Here, if it is determined that the sampling container or the replenishing container has been placed (S201: Yes), the process proceeds to step S21. On the other hand, when it is determined that the sampling container or the replenishing container is not placed (S201: No), the infusion volume control process ends. Thus, instead of the method of determining the presence or absence of a change in the amount of liquid in the infusion bag 12 as in Step S23 and Step S211, the presence or absence of the extraction container or the replenishment container in Step S201 is determined. It is also possible to judge. In addition, in the said step S201, the said 2nd control part 500 may judge whether the said extraction data contain the said extraction container or the said replenishment container as a required equipment.

[Third Embodiment]
In the mixed injection device 1, the mixed injection process is started when it is detected by a sensor (not shown) that the tray 101 is loaded from the tray insertion port 114 after the loading preparation process is completed. In contrast, in the present embodiment, the first control unit 400 and the second control unit 500 can automatically start the mixed injection process based on the preparation data at a reserved execution time. explain.

[Reservation setting process]
First, an example of a reservation setting process executed by the first control unit 400 will be described with reference to FIG.

<Step S31>
First, in step S31, the first control unit 400 waits for a user's reservation setting operation on the operation unit 405 (S31: No). When the first control unit 400 determines that the reservation setting operation has been performed (S31: Yes), the first control unit 400 shifts the processing to step S32.

  Specifically, the first control unit 400 displays the reservation screen when a predetermined operation for displaying the reservation screen using the operation unit 405 is performed, and displays the reservation screen. The reservation setting operation of the mixed injection process based on the preparation data is accepted in accordance with the operation of the operation unit 405 during the display. In the reservation setting operation, the preparation data to be reserved is selected, and the completion time of the mixed injection process of the preparation data is designated. In the reservation setting operation, the start time of the mixed injection process may be designated instead of the completion time of the mixed injection process of the preparation data. For example, the completion time or the start time is designated by inputting a date and time. The completion time or the start time may be specified by inputting an elapsed time from the current date and time.

<Step S32>
In step S32, the first control unit 400 determines whether the total number of the preparation data already reserved and the current reservation is within a predetermined maximum number of reservations. The maximum number of reservations is a number determined in advance by the specifications of the co-infusion apparatus 1 and corresponds to the number of trays 101 that can be loaded into the co-infusion apparatus 1. In the co-infusion apparatus 1 according to the present embodiment, since there is one tray 101 that can be inserted into the tray insertion port 114, it is determined in step S32 whether there is already prepared preparation data. Will be judged. If the first controller 400 determines that the total is within the maximum number of reservations (S32: Yes), the first controller 400 shifts the process to step S33. If the first control unit 400 determines that the total is not within the maximum number of reservations (S32: No), for example, after displaying a predetermined error message, the process returns to step S31.

<Step S33>
In step S33, the first control unit 400 executes a process for arbitrarily reserving the mixed injection process based on the preparation data in accordance with the reservation setting operation. Here, the first control unit 400 when executing the process for enabling reservation of the mixed injection process is an example of a reservation setting processing unit. Specifically, the first control unit 400 executes a time when the mixed injection process based on the preparation data is completed at the completion time based on the preparation data and the completion time designated by the reservation setting operation. Specify as a time. Therefore, for example, the data storage unit 404 stores a required time for each preparation content specified by the preparation data, or stores information for calculating the required time, and the first control unit 400 Specifies the execution time based on the required time. In addition, when the start time of the mixed injection process is designated by the reservation setting operation, the start time is specified as the execution time. Then, the first control unit 400 transmits reservation information such as the execution time set for the preparation data together with the preparation data to the second control unit 500. For example, the reservation information includes, in addition to the execution time, information indicating a correspondence relationship between information for identifying the preparation data to be reserved and the identification information of the tray 101 corresponding to the preparation data. included. The first control unit 400 can cancel or change the reservation of the mixed injection process based on the preparation data set in the reservation setting process.

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

<Step S41>
In step S41, the second control unit 500 determines whether or not the tray 101 is loaded in the mixed injection processing unit 300 (S41: No). Specifically, the second control unit 500 loads the tray 101 when identification information is read by the IC reader 101c from the IC tag 101b of the tray 101 loaded from the tray insertion port 114. Judge that If the second controller 500 determines that the tray 101 is loaded (S41: Yes), the process proceeds to step S42. The second control unit 500 waits for the process in step S41 until it is determined that the tray 101 is loaded (S41: No).

  In the present embodiment, a case will be described in which execution of the mixed injection process is suspended while the tray 101 is loaded from the tray insertion port 114. Accordingly, for example, when the execution of the mixed injection process based on the preparation data is canceled, the tray 101 can be discharged from the tray insertion port 114.

  On the other hand, when the tray 101 is loaded in the mixed injection processing unit 300, the second control unit 500 executes the mixed injection processing with the equipment in the tray 101 taken into the mixed injection processing unit 300. It is possible to hold it. Specifically, the medicine container 10 and the syringe 11 placed on the tray 101 are taken into the mixed injection processing chamber 104. As described above, the medicine container 10 and the syringe 11 are accommodated in the mixed injection processing chamber 104 provided with the exhaust system (not shown), whereby dust on the medicine container 10 and the syringe 11 and the like is collected. Is suppressed, and the user's hand and the like are prevented from touching the drug container 10 and the syringe 11. In addition, it is conceivable that the infusion bag 12 placed on the tray 101 is transported to the tray transport terminal portion 110a after the equipment is taken out from the tray 101. Thereby, adhesion of dust is suppressed also about the infusion bag 12, and a user's hand etc. are prevented from touching.

<Step S42>
In step S42, the second controller 500 determines whether or not the tray 101 loaded in the tray insertion port 114 corresponds to the preparation data that has reached the execution time. Specifically, the second control unit 500 determines whether the preparation data to be reserved is associated with the identification information read from the IC tag 101b of the tray 101 by the IC reader 101c. . For example, the reservation information received from the first control unit 400 includes information indicating a correspondence relationship between the preparation data to be reserved in the reservation information and the identification information of the tray 101. It is conceivable that the control unit 500 determines whether or not the tray 101 corresponds to the preparation data that has reached the execution time based on the reservation information. When the second control unit 500 determines that the tray 101 corresponds to the preparation data that has reached the execution time (S42: Yes), the process proceeds to step S43. On the other hand, when the second control unit 500 determines that the tray 101 does not correspond to the preparation data for which the execution time has come (S42: No), the process proceeds to step S44. Even if the determination of the suitability of the tray 101 is not executed, an error occurs when it is determined that the equipment stored in the tray 101 and the preparation data do not match in the mixed injection process. The process of step S42 may be omitted. That is, the second control unit 500 uses the tray 101 loaded in the tray insertion port 114 without determining whether or not the tray 101 is appropriate when the execution time has arrived. It is conceivable to start execution. In this case, the reservation information may not include information indicating a correspondence relationship between the preparation data to be reserved in the reservation information and the identification information of the tray 101.

<Step S43>
In step S43, the second control unit 500 waits for the execution time received from the first control unit 400 to arrive (S43: No). And if the said 2nd control part 500 judges that the said execution time has come (S43: Yes), it will transfer a process to step S44.

<Step S44>
In step S <b> 44, the second control unit 500 starts the mixed injection process based on the preparation data corresponding to the tray 101 loaded in the tray insertion port 114. That is, when the tray 101 is the preparation data to be reserved, the mixed injection process is started at the timing when the execution time has come. Here, the second control unit 500 when executing the processing is an example of the reservation execution processing unit. On the other hand, when the tray 101 is not the preparation data to be reserved, the mixed injection process is started at the timing when the tray 101 is loaded in the tray insertion port 114.

  Thereby, the mixed injection apparatus 1 can execute the mixed injection process at a predetermined execution time such as midnight or a holiday by reserving execution of the mixed injection process of the preparation data.

  Here, the case where the execution of the mixed injection process is started when the execution time of the mixed injection process set in the reservation setting process comes by the second control unit 500 has been described as an example. It is also conceivable that the first control unit 400 determines whether or not the execution time of the mixed injection process set in the reservation setting process has come. In this case, when the execution time comes, the first control unit 400 transmits the preparation data to the second control unit 500 to start the mixed injection process. That is, the first control unit 400 may be an example of the reservation execution processing unit.

  By the way, in this embodiment, the structure which can insert one said tray 101 in the said co-infusion apparatus 1 was demonstrated. On the other hand, the mixed injection device 1 includes a tray storage unit that stores the plurality of trays 101, and a tray insertion unit that takes out the arbitrary tray 101 from the tray storage unit and inserts the tray 101 into the tray insertion port 114. Other embodiments are possible. Thereby, in the reservation setting process, it is possible to accept reservations for the mixed injection process of a plurality of the preparation data, and in the mixed injection control process, the mixed injection process for each of the reserved preparation data It can be started at the time of execution.

[Fourth Embodiment]
By the way, it is conceivable that the mixed injection device 1 has a preparation list output function capable of outputting a preparation schedule list sheet S100 indicating a schedule for executing the mixed injection processing based on the preparation data received from the host system 600. Thereby, the user can confirm in advance the execution schedule of the mixed injection process based on the preparation data with reference to the preparation schedule list sheet S100.

  Specifically, the first control unit 400 inputs a condition for creating the preparation schedule list sheet S100 in response to a preset list output request operation for the operation unit 405 (not shown). Is displayed. In the creation conditions, as the conditions for narrowing down the preparation data to be output to the preparation schedule list sheet S100, for example, the contents of items such as the preparation date, prescription classification, medical department, and ward included in the preparation data are specified. The Then, when the creation condition is input on the condition input screen, the first control unit 400 reads the preparation data that matches the creation condition from the data recording unit 404 and outputs the preparation schedule list sheet S100. Data is created and displayed on the display 203.

  FIG. 32 is a diagram showing an example of the preparation schedule list sheet S100. As shown in FIG. 32, in the preparation schedule list sheet S100, the preparation data that matches the creation conditions are displayed in a list, and an area A32 indicating the necessity and content of the preliminary work for each of the preparation data, etc. Information is displayed. Specifically, the first control unit 400 displays a blank in the area A32 for the preparation data that does not require the prior work among the preparation data. On the other hand, the first control unit 400 displays “manually extracted” characters in the area A32 for the preparation data that requires the sampling operation as the preliminary operation in the preparation data. In addition, the first control unit 400 displays “hand injection” in the area A32 for the preparation data that requires the replenishment operation or the injection operation as the preliminary operation in the preparation data. In the region A32, the replenishment operation and the injection operation may be displayed so as to be identifiable with different characters.

  Thereafter, the first control unit 400 is connected to the co-infusion apparatus 1 so as to be communicable with the co-infusion apparatus 1 in accordance with a user operation on the operation unit 405, or a printer (not illustrated) provided in the co-infusion apparatus 1. Print data of the preparation schedule list sheet S100. Accordingly, the preparation schedule list sheet S100 is printed by the printer. It is also conceivable that the host system 600 can display or print out the preparation schedule list sheet S100.

  Thus, in the configuration in which the preparation schedule list sheet S100 can be output by the mixed injection device 1 or the host system 600, the user can grasp in advance the execution schedule of the mixed injection processing based on the preparation data. In particular, in the preparation schedule list sheet S100, whether or not the preliminary work is necessary is displayed, so that it is possible to grasp in advance the amount of work of the user accompanying the execution of the mixed injection process for each of the preparation data. .
