DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] [Embodiment 1] An embodiment of the present invention will be described in detail below. In each drawing, the X-axis and the Y-axis are two mutually perpendicular axes in a horizontal plane (the ground surface of the co-infusion device 1). The positive X-axis direction may be referred to as the right direction, and the negative X-axis direction as the left direction. The positive Y-axis direction may be referred to as the back direction or rear direction, and the negative Y-axis direction as the front direction or forward direction. The Z-axis is an axis that extends vertically to the XY plane, and the positive Z-axis direction may be referred to as the upward direction, and the negative Z-axis direction as the downward direction.

[0011] [Overall configuration of the co-infusion device] Fig. 1 is a perspective view showing an example of the overall configuration of a co-infusion device 1. As shown in Fig. 1, the co-infusion device 1 according to this embodiment includes a syringe shelf 10, a vial shelf 20, an infusion shelf 30, a printing / inspection unit 50, an infusion receiving shelf 60, a wastebasket section 70, a touch panel 80, and a button 90.

[0012] The co-infusion device 1 is a device that executes a co-infusion process (co-infusion operation) of mixing a drug and an infusion using a drug indicated in data related to preparation and administration (hereinafter referred to as preparation and administration data), a syringe, and an infusion. For example, the co-infusion device 1 executes the co-infusion process by using a syringe to aspirate a drug indicated in the preparation and administration data from a vial (an example of a drug container) in which the drug is contained, and injecting the drug from the syringe into an infusion container (infusion bag). The infusion used in the co-infusion process may be, for example, saline (physiological saline) or a liquid containing glucose.

[0013] Other examples of the co-infusion process include a process of aspirating a medicine from a vial using a syringe and injecting it into another vial, or a process of aspirating an infusion from an infusion container using a syringe and injecting it into a vial. When a solid medicine is contained in a vial, the co-infusion device 1 uses a syringe to aspirate the infusion from the infusion container and injects the infusion into the vial. This makes it possible to turn the solid medicine into a liquid in the vial. Then, the co-infusion device 1 uses the syringe to inject the liquid medicine into the infusion container.

[0014] The co-infusion device 1 allows a user to load a syringe, a vial, and an infusion container into the co-infusion device 1 by opening and closing a door, for example. The air purifying unit described below keeps the inside of the co-infusion device 1 clean, reducing the possibility of contamination of the medicine and the infusion during the co-infusion process. In addition, in order to keep the inside of the co-infusion device 1 clean, the inside of the co-infusion device 1 is kept at a positive pressure.

[0015] In addition, the above preparation and administration data is data required by the control unit 140 (see Figure 4) of the co-infusion device 1 to perform the co-infusion process and the printing process of the second label (see symbol 1062 in Figure 20), and is generated based on the prescription data.

[0016] The preparation and administration data includes, for example, information indicating the type of drug used in the mixed injection process, the prescribed amount of the drug, information indicating the type of syringe, information indicating the type of infusion (infusion type information), and information indicating the amount of infusion withdrawn from the infusion container.

[0017] Furthermore, the preparation / administration data includes information about the infusion container 503 into which the medicine is injected, as information to be printed on the second label LA12. This information includes prescription attribute information, prescription detail information, an order number indicating the order in which the prescription was received, and infusion type information (e.g., infusion name), etc.

[0018] The prescription attribute information includes information indicating the name and patient ID of the patient for whom the drug has been prescribed, the name of the ward and room in which the patient is hospitalized, the name of the department to which the medical professional who will administer the mixed drug to the patient belongs, and the date on which the mixing device 1 performed the mixing process (the date on which the prescribed drug was injected into the infusion container), etc.

[0019] The prescription details information includes information indicating the Rp (recipe) number, infusion technique, route, drug name (an example of information indicating the type of drug), usage, dosage, comments, etc. The Rp is information including the drug name, usage, dosage, etc. The route is information indicating the destination into the body of the liquid in the infusion container into which the drug has been injected (e.g. peripheral vein or peripheral internal jugular).

[0020] The information regarding the infusion container 503 into which the medicine has been injected may include at least information indicating the medicine name, the patient name, the hospital room name, and the date of mixed injection.

[0021] The syringe shelf 10 is an equipment storage shelf capable of storing the syringes loaded in the co-infusion device 1. The syringe shelf 10 is provided with a syringe-side door 16. A user can hold the syringe on the syringe shelf 10 by opening and closing the syringe-side door 16.

[0022] The vial shelf 20 is an equipment storage shelf capable of storing the vials filled in the co-infusion device 1. The vial shelf 20 is provided with a vial-side door 27. A user can cause the vial shelf 20 to hold the vial by opening and closing the vial-side door 27.

[0023] The infusion shelf 30 is an infusion storage shelf capable of storing the infusion containers filled in the co-infusion device 1. The infusion shelf 30 is provided with an infusion side door 34. A user can hold the infusion container in the infusion side door 34 by opening and closing the infusion side door 34.

[0024] The syringe side door 16, the vial side door 27, and the infusion side door 34 are doors that can block the user's access to the syringe shelf 10, the vial shelf 20, and the infusion shelf 30, respectively. In the co-infusion device 1, the control unit 140 described later controls the syringe side door 16, the vial side door 27, and the infusion side door 34 so that only one of them is in an unlocked state.

[0025] The printing and inspection unit 50 is a unit that prints the second label LA12 and affixes it to the infusion container before or after drug injection. The printing and inspection unit 50 may print an inappropriate information label (described later) and affix it to the infusion container after drug injection. The printing and inspection unit 50 is also a unit that weighs the infusion container before and after drug injection.

[0026] The infusion receiving shelf 60 is a unit that receives infusion containers with a second label LA12 affixed thereto after drug injection. The infusion receiving shelf 60 is provided with an infusion receiving door 61. The trash can section 70 is a box that receives used syringes. The touch panel 80 has the functions of an operation section that receives various operations by the user, and a display section that displays various information. The operation section and the display section may be provided as separate members. Also, instead of the display section, a presentation section (e.g., a speaker) that presents various information may be provided.

[0027] The button 90 is a mechanical button that can receive a user operation to unlock the syringe side door 16, the vial side door 27, the infusion side door 34, and the infusion receiving door 61. One button 90 is provided for each of the syringe side door 16, the vial side door 27, the infusion side door 34, and the infusion receiving door 61. When the syringe side door 16, the vial side door 27, the infusion side door 34, and the infusion receiving door 61 are closed, they are locked by a locking mechanism (not shown). The syringe side door 16, the vial side door 27, the infusion side door 34, and the infusion receiving door 61 are unlocked only when the user presses the button 90. However, when it becomes possible to unlock any of the doors to open them, the control unit 140 described later invalidates the user operation on the button 90 corresponding to the door that is closed and locked. As a result, the control unit 140 maintains the doors other than the unlocked door in a closed and locked state.

[0028] The control unit 140 does not release the lock even when the button 90 corresponding to the door of the syringe shelf 10, the vial shelf 20, the infusion shelf 30, or the infusion receiving shelf 60 that is being accessed by the first transport unit 110 or the second transport unit 120 described below is pressed. Furthermore, a light emitting member (not shown) may be provided corresponding to each of the syringe shelf 10, the vial shelf 20, the infusion shelf 30, and the infusion receiving shelf 60. The control unit 140 may light up the light emitting member corresponding to the shelf accessed by the first transport unit 110 or the second transport unit 120. In this case, a locking mechanism for each door may not necessarily be provided.

[0029] [Overview of the internal configuration of the co-infusion device] Fig. 2 is a perspective view showing an example of a schematic internal configuration of the co-infusion device 1 when viewed from the front (near side). Fig. 3 is a perspective view showing an example of a schematic internal configuration of the co-infusion device 1 when viewed from the rear (rear direction).

[0030] As shown in Figures 2 and 3, the co-infusion device 1 includes the above-mentioned syringe shelf 10, vial shelf 20, infusion shelf 30, printing / inspection unit 50, infusion receiving shelf 60, and trash can section 70, as well as a co-infusion unit 40, a first conveying section 110, a second conveying section 120, and an air purifying section 130.

[0031] The mixing unit 40 functions as an injection unit that injects a medicine into an infusion container 503 that contains an infusion. The mixing unit 40 injects a medicine into the infusion container 503, so that the medicine is mixed with the infusion in the infusion container 503. The mixing unit 40 also functions as a member that extracts the infusion from the infusion container 503. The mixing unit 40 can inject the infusion into the vial 502 by extracting the infusion from the infusion container 503. This allows the solid medicine contained in the vial 502 to be liquidized. In this embodiment, the mixing unit 40 is located between the syringe shelf 10 and the vial shelf 20 and the infusion shelf 30 and the infusion receiving shelf 60.

[0032] The first transport unit 110 functions as a container transport unit that transports the syringe 501 indicated in the preparation / administration data from the syringe shelf 10 to the mixed injection unit 40, or transports the vial containing the drug indicated in the preparation / administration data from the vial shelf 20 to the mixed injection unit 40. When the preparation / administration data is input, the first transport unit 110 transports the syringe 501 stored on the syringe shelf 10 and the vial 502 stored on the vial shelf 20 to the mixed injection unit 40. In this embodiment, the first transport unit 110 grasps the upper part of the body of the syringe 501 stored on the syringe shelf 10 and delivers the syringe 501 to the mixed injection unit 40. Similarly, the first transport unit 110 grasps the neck of the vial 502 stored on the vial shelf 20 and delivers the vial 502 to the mixed injection unit 40.

[0033] In addition, the first transport section 110 transports the syringe 501 stored in the syringe shelf 10 to a cap attachment / detachment section (not shown) before transporting the syringe 501 to the mixed injection unit 40. This allows the first transport section 110 to remove the needle cap attached to the needle of the syringe 501, and transport the syringe 501 with the needle cap removed to the mixed injection unit 40. In addition, the first transport section 110 transports the syringe 501 and the vial 502 after the mixed injection process (the syringe 501 and the vial 502 that are no longer needed) to the trash can section 70.

[0034] The first transport unit 110 is a transport unit that transports the syringe 501 and the vial 502 and is shared by both the syringe 501 and the vial 502, but is not limited thereto. A transport unit dedicated to transporting the syringe 501 and a transport unit dedicated to transporting the vial 502 may be provided separately.

[0035] The second transport unit 120 functions as an infusion container transport unit that transports the infusion container 503 indicated in the preparation / administration data between the infusion shelf 30, the mixing unit 40, the printing / inspection unit 50, and the infusion receiving shelf 60.

[0036] The second transport unit 120 transports the infusion container 503 to the mixing unit 40. When the preparation / administration data is input, the second transport unit 120 transports the infusion container 503 stored in the infusion shelf 30 to the mixing unit 40. In this embodiment, the second transport unit 120 picks up the body of the infusion container 503 stored in the infusion shelf 30 and delivers it to the mixing unit 40.

[0037] In addition, the second transport unit 120 transports the infusion container 503 between the mixing unit 40 and the printing and inspection unit 50. In this embodiment, for example, the second transport unit 120 picks up the body of the infusion container 503 after the medicine is injected, and transports it to the printing and inspection unit 50.

[0038] The second transport section 120 also functions as a delivery section that delivers the infusion container 503 into which a drug has been injected by the mixing unit 40 to the infusion receiving shelf 60. In this embodiment, the second transport section 120 adsorbs the body of the infusion container 503 after drug injection to which second information different from the first information has been attached by the printing / inspection unit 50 (to which the second label LA12, or the second label LA12 and an inappropriate information label have been affixed), and delivers it to the infusion receiving shelf 60. Details of the first information and the second information will be described later.

[0039] The air purifying unit 130 purifies and exhausts the air inside the co-infusion device 1. In this embodiment, it is provided at the top of the co-infusion device 1. The air purified by the air purifying unit 130 flows from the top to the bottom of the co-infusion device 1. The air purifying unit 130 has, for example, a HEPA (High Efficiency Particulate Air) filter.

[0040] The arrangement of each component in the co-infusion device 1 is not limited to the above arrangement. For example, the vial shelf 20 may be provided on the upper stage of the syringe shelf 10. The syringe shelf 10 and the vial shelf 20 may be provided on the upper stage of the infusion shelf 30, the infusion receiving shelf 60, and the printing and inspection unit 50. In the present embodiment, the syringe shelf 10, the vial shelf 20, and the infusion shelf 30 are provided on multiple stages, but each may be provided on one stage. In the present embodiment, the infusion receiving shelf 60 is provided on one stage, but each may be provided on one stage. The printing and inspection unit 50 and the infusion receiving shelf 60 may be provided on the opposite stage. The arrangement of each component in the co-infusion device 1 may be determined in consideration of the convenience of the user and the ease of manufacture.

[0041] In addition, a syringe side door 16 and / or a vial side door 27 may be provided on the side of the co-infusion device 1 (FIG. 2, right side of the paper). As described later, one syringe 501 and one vial 502 are loaded from the front side of the co-infusion device 1. On the other hand, multiple syringes 501 or multiple vials 502 can be loaded from the side side of the co-infusion device 1. When the infusion shelf 30 has the same configuration as the syringe shelf 10 and the vial shelf 20, an infusion side door 34 may be provided on the side side of the co-infusion device 1 (FIG. 2, left side of the paper).

[0042] [Other configurations] Fig. 4 is a block diagram showing an example of the overall configuration of the co-infusion device 1. As shown in Fig. 4, the co-infusion device 1 includes a control unit 140 and a storage unit 200. Note that Fig. 4 shows only the main hardware configuration that can be controlled by the control unit 140 among the hardware configurations included in the co-infusion device 1.

[0043] The control unit 140, based on the preparation and administration data, controls the overall operation of the co-infusion device 1. The control unit 140 includes, for example, a syringe transport control unit 141, a vial transport control unit 142, a first transport control unit 143, a co-infusion unit control unit 144, a second transport control unit 145, a pushing control unit 147, a printing and inspection unit control unit 148, and a touch panel control unit 149.

[0044] The syringe transport control unit 141 controls the operation of members related to the transport of the syringe 501 in the syringe shelf 10. The vial transport control unit 142 controls the operation of members related to the transport of the vial 502 in the vial shelf 20. The mixed injection unit control unit 144 controls the operation of members provided in the mixed injection unit 40.

[0045] The first transport control unit 143 controls the operation of the members included in the first transport unit 110. The first transport control unit 143 controls the movement of the first transport unit 110 between, for example, the syringe shelf 10, the vial shelf 20, the mixed injection unit 40, the wastebasket unit 70, and the cap attachment / detachment unit (not shown). The second transport control unit 145 controls the operation of the members included in the second transport unit 120. The second transport control unit 145 controls the movement of the second transport unit 120 between, for example, the infusion shelf 30, the mixed injection unit 40, the printing / inspection unit 50, and the infusion receiving shelf 60.

[0046] The pushing control unit 147 controls the operation of members related to the transportation of the infusion container 503 in the infusion shelf 30. The printing and inspection unit control unit 148 controls the operation of members provided in the printing and inspection unit 50. The touch panel control unit 149 controls the touch panel 80.

[0047] The storage unit 200 also stores data for the mixed injection process and printing process performed by the control unit 140. The storage unit 200 stores, for example, preparation and administration data.

[0048] [Specific configuration of the mixing unit] Fig. 5 is a perspective view showing an example of the configuration of the co-injection unit 40. Fig. 6 is a front view showing an example of the schematic configuration of the co-injection unit 40, and is a diagram for explaining an example of the operation of the co-injection unit 40. Fig. 7 is a diagram for explaining adjustment of the needle tip position of the syringe 501.

[0049] As shown in FIG. 5, the co-infusion unit 40 includes a syringe holder 41, a vial holder 42, an infusion container holder 43, a stopper position detector 45, and a first detector 46.

[0050] The syringe holding section 41 is a member that holds the syringe 501 (the syringe 501 transported by the first transport section 110) for injecting a medicine into the infusion container 503. The syringe 501 includes a syringe 5011, a needle 5014, and a plunger 5015. The plunger 5015 is a pusher that moves in and out of the syringe 5011. The plunger 5015 moves in and out of the syringe 5011, thereby drawing in a medicine or the like into the syringe 5011 and discharging the medicine or the like from the syringe 5011. The syringe 5011 includes a needle-side end section 5012 to which the needle 5014 is attached, and a flange 5013 that is an end section opposite to the needle-side end section 5012 and is an end section on the side where the plunger 5015 moves in and out.

[0051] Syringe holding portion 41 includes needle clamping portion 411, position fixing portion 412, first syringe holding portion 416, and plunger clamping portion 417. Note that in this specification, the member described as holding the object is merely an example, and the member may be any member capable of holding the object.

[0052] The needle clamping part 411 is a member that clamps the needle 5014. The needle clamping part 411 clamps the needle 5014 and positions the tip of the needle 5014 at a fixed position. This allows even a bent needle 5014 to be punctured at a desired position (correct position) of a stopper provided on the infusion container 503 during mixed injection processing.

[0053] The first syringe holding portion 416 is a member that first holds the syringe 501 that the first transporting portion 110 has transported from the syringe shelf 10. The first syringe holding portion 416 holds the side of the syringe 5011 (e.g., the lower portion of the syringe 5011) inserted into the first syringe holding portion 416.

[0054] The position fixing part 412 is a member that fixes the position of the syringe 501 in the extension direction of the syringe 501 at the needle side end part 5012 and the flange 5013. In this embodiment, the relative positions of the second syringe holding part 413 and the third syringe holding part 414 that constitute the position fixing part 412 can be changed along the extension direction of the syringe 501. The second syringe holding part 413 and the third syringe holding part 414 are attached such that at least one of the second syringe holding part 413 and the third syringe holding part 414 is movable along the extension direction of the syringe 501.

[0055] In this embodiment, when the syringe 501 is held by the position fixing part 412, the second syringe holding part 413 abuts from the lower side of the needle side end part 5012, and the third syringe holding part 414 abuts from the upper side of the flange 5013. This allows the position fixing part 412 to clamp the syringe 501 along the extension direction of the syringe 501. By clamping along the extension direction of the syringe 501, the position fixing part 412 can fix the syringe 5011 so that it does not slip in the extension direction of the syringe 501 with a smaller force than when clamping only the side surface of the syringe 5011. Furthermore, since the syringe 5011 is not deformed by clamping the side surface, smooth operation of the plunger 5015 is possible. Therefore, the accuracy of adjustment of the suction and injection amount of the syringe 501 is improved.

[0056] The plunger clamping portion 417 is a member that clamps the plunger 5015. In this embodiment, the plunger clamping portion 417 clamps the tip portion of the plunger 5015. The plunger clamping portion 417 moves in the vertical direction relative to the needle clamping portion 411, the position fixing portion 412, and the first syringe holding portion 416, thereby allowing the plunger 5015 to move relative to the syringe 5011.

[0057] The vial holder 42 is a member that holds a vial 502 (the vial 502 transported by the first transporter 110) that contains a medicine to be injected into the infusion container 503. In this embodiment, the vial holder 42 holds the neck of the vial 502.

[0058] The infusion container holding part 43 is a member that holds the infusion container 503 (the infusion container 503 transported by the second transport part 120). In this embodiment, the infusion container holding part 43 includes an infusion clamping part 431 that clamps the neck part of the infusion container 503, and a mounting base 432 on which the infusion container 503 is placed when extracting infusion from the infusion container 503 or when injecting infusion into the infusion container 503.

[0059] 5 and 6, the co-infusion unit 40 is provided on a side wall of the infusion shelf 30. Specifically, in the co-infusion device 1, the co-infusion unit 40 is arranged so that the syringe holder 41, the vial holder 42, and the infusion container holder 43 face toward the syringe shelf 10 and the vial shelf 20 (+X-axis direction).

[0060] 6, the syringe holding part 41 is movable in the vertical direction (±Z-axis direction). This allows the needle 5014 to puncture the vial 502 or the infusion container 503 located directly below the syringe 501 held by the syringe holding part 41.

[0061] The vial holding part 42 and the infusion container holding part 43 are movable in the front-rear direction (±Y-axis direction) of the co-infusion device 1. In this embodiment, the vial holding part 42 and the infusion container holding part 43 are attached to a base 44, and the base 44 moves in the front-rear direction of the co-infusion device 1. The base 44 functions as a moving part that moves the vial holding part 42 and the infusion container holding part 43 in a direction (±Y-axis direction) perpendicular to the extension direction (±Z-axis direction) of the needle 5014 of the syringe 501 held by the syringe holding part 41. The direction perpendicular to the extension direction of the needle 5014 may be simply referred to as the direction perpendicular to the needle 5014.

[0062] This allows the vial holding part 42 and the infusion container holding part 43 to move between a position indicated by reference numeral 1001 in Fig. 6 and a position indicated by reference numeral 1002 in Fig. 6. The position indicated by reference numeral 1001 in Fig. 6 is a first puncture position when the needle 5014 punctures the vial 502, and the position indicated by reference numeral 1002 in Fig. 6 is a second puncture position when the needle 5014 punctures the infusion container 503. Therefore, the vial 502 held in the vial holding part 42 or the infusion container 503 held in the infusion container holding part 43 can be positioned at the puncture position of the needle 5014 of the syringe 501 held in the syringe holding part 41.

[0063] The base 44 is an example of the moving part, and the moving part is not limited to the base 44, but may be any member that moves the vial holding part 42 and the infusion container holding part 43 in a direction perpendicular to the needle 5014. The moving part may move the syringe holding part 41 relative to the vial holding part 42 and the infusion container holding part 43 in a direction perpendicular to the needle 5014. The moving part may be any member that moves the vial holding part 42 and the infusion container holding part 43 relative to the syringe holding part 41.

[0064] 6, the co-infusion unit 40 is provided rotatably around a rotation axis Ax (Ax is the rotation axis). The rotation axis Ax is an axis extending in a direction perpendicular to the base on which the syringe holder 41, the vial holder 42, and the infusion container holder 43 are provided (±X-axis direction).

[0065] At the first puncture position indicated by reference numeral 1001 in Fig. 6, the mixing unit 40 rotates about the rotation axis Ax, thereby moving the vial 502 above the syringe 501. At the second puncture position indicated by reference numeral 1002 in Fig. 6, the mixing unit 40 rotates about the rotation axis Ax, thereby moving the infusion container 503 above the syringe 501. In these states, the mixing unit 40 moves the plunger 5015 downward to move the medicine contained in the vial 502 or the infusion contained in the infusion container 503 to the syringe 5011.

[0066] The infusion liquid contained in the syringe 5011 is injected into the vial 502 in the state of reference numeral 1001 in Fig. 6 (where the vial 502 is located directly below the syringe 501). Similarly, the medicine contained in the syringe 5011 is injected into the infusion container 503 in the state of reference numeral 1002 in Fig. 6 (where the infusion container 503 is located directly below the syringe 501).

[0067] 6, the infusion container 503 has a first surface SF1 and a second surface SF2. The first surface SF1 and the second surface SF2 are opposite surfaces of the infusion container 503 and are main surfaces of the infusion container 503. The main surface of the infusion container 503 refers to the surface having the largest area among the multiple surfaces constituting the infusion container 503.

[0068] In the infusion shelf 30, the infusion container 503 is stored so that the first surface SF1 and the second surface SF2 of the infusion container 503 face a predetermined direction. In this embodiment, the infusion container 503 is held on the rail section 36 of the infusion shelf 30 so that the first surface SF1 faces the back of the co-infusion device 1 and the second surface SF2 faces the front of the co-infusion device 1. Then, the second transport section 120 sucks the first surface SF1 in the infusion shelf 30 to hold the infusion container 503, and transports and delivers the infusion container 503 to the infusion container holding section 43 without changing its orientation. Thereafter, in order to extract the infusion from the infusion container 503, the co-infusion unit 40 rotates around the rotation axis Ax. As a result, the infusion container 503 is placed on the placement table 432 with the second surface SF2 abutting against the placement table 432.

[0069] In this way, the mounting table 432 rotates on the horizontal plane (XY plane) around the rotation axis Ax perpendicular to the above-mentioned predetermined direction (±Y-axis direction). Therefore, as described above, the infusion container 503 can be mounted on the mounting table 432 without changing the orientation of the infusion container 503 transported from the infusion shelf 30. Therefore, in order to mount the infusion container 503 on the mounting table 432, it is not necessary to provide the co-infusion device 1 with a mechanism for changing the orientation of the infusion container 503.

[0070] In addition, the surface of the mounting base 432 is approximately parallel to the X-axis direction. Therefore, by rotating the mixing unit 40 around the rotation axis Ax and adjusting the rotation position of the mixing unit 40, the surface of the mounting base 432 can be oriented in a predetermined direction in which the first surface SF1 and the second surface SF2 of the infusion container 503 are oriented, without changing the orientation of the infusion container 503. By orienting the surface of the mounting base 432 and the first surface SF1 and the second surface SF2 of the infusion container 503 in the same direction, it is possible to reduce the deformation of the infusion container 503 when the infusion container 503 is brought into contact with the mounting base 432. In addition, it is possible to reduce the movement of the position of the part of the infusion container 503 in which the liquid is contained (for example, the body of the infusion container 503) when the infusion container 503 is brought into contact with the mounting base 432.

[0071] Returning to Fig. 5, stopper position detection unit 45 is a sensor that detects the position of rubber stopper 5021 of vial 502 held in vial holding unit 42. Rubber stopper 5021 is provided on the upper surface of vial 502 and is a member that is punctured by needle 5014. In this embodiment, stopper position detection unit 45 is disposed at a position that is directly above vial holding unit 42 at the second puncture position indicated by reference numeral 1002 in Fig. 6. Stopper position detection unit 45 may be, for example, a distance measurement sensor.

[0072] The first detection unit 46 detects the tip of the needle 5014 of the syringe 501 held in the syringe holding unit 41. The syringe holding unit 41 moves downward when the needle 5014 punctures the vial 502 held in the vial holding unit 42 or the infusion container 503 held in the infusion container holding unit 43. The first detection unit 46 detects the tip of the needle 5014 that has moved in conjunction with this downward movement. The first detection unit 46 may be, for example, an optical sensor including a light receiving unit that receives light reflected by the needle 5014.

[0073] Reference distance information indicating the distance in the vertical direction between the position where the stopper position detection unit 45 detects the target and the position where the first detection unit 46 detects the target is stored in advance in the storage unit 200. The mixed injection unit control unit 144 can calculate the distance from the position of the needle 5014 that passed in front of the first detection unit 46 to the rubber stopper 5021 from the difference between the distance from the stopper position detection unit 45 to the rubber stopper 5021 detected by the stopper position detection unit 45 and the distance indicated by the reference distance information.

[0074] As described above, the vial holding section 42 moves in a direction perpendicular to the needle 5014 (±Y-axis direction). Therefore, the position of the vial 502 in the vertical direction is almost the same at the first puncture position indicated by reference numeral 1001 in FIG. 6 and the second puncture position indicated by reference numeral 1002 in FIG. 6. Therefore, the position of the rubber stopper 5021 detected by the stopper position detection section 45 at the second puncture position can also be applied to the first puncture position. Therefore, the co-infusion unit control section 144 can puncture the rubber stopper 5021 with only the needle tip of the needle 5014 by moving the needle 5014 that has passed in front of the first detection section 46 downward by the calculated distance.

[0075] If the tip of needle 5014 is inserted too deeply into vial 502, not all of the medicine contained in vial 502 can be drawn into syringe 501. By inserting the needle tip into vial 502 with precision as described above, most of the medicine contained in vial 502 can be drawn into syringe 501.

[0076] 7, the co-injection unit 40 may further include a second detection unit 47. The second detection unit 47 is a sensor that detects the syringe holding unit 41 directly above the first detection unit 46. The second detection unit 47 may be an optical sensor, similar to the first detection unit 46. By using the first detection unit 46 and the second detection unit 47, the co-injection unit control unit 144 can detect the tip position of the needle 5014 of the syringe 501 held by the syringe holding unit 41.

[0077] Specifically, as shown by reference numeral 1011 in FIG. 7, after the jig 601 (reference syringe) is attached to the syringe holding part 41, the syringe holding part 41 is moved downward at a predetermined speed V. The mixed injection unit control part 144 measures a first detection time T1 from when the second detection part 47 detects the syringe holding part 41 to when the first detection part 46 detects the needle of the jig 601. The tip position of the needle of the jig 601 when the second detection part 47 detects the syringe holding part 41 is measured by a person or the like and stored in advance in the storage part 200. The position serving as the measurement reference for the tip position can be set arbitrarily.

[0078] As shown by reference numeral 1012 in FIG. 7, the syringe 501 actually used in the mixed injection process is attached to the syringe holding part 41, and the syringe holding part 41 is moved downward at a predetermined speed V. The mixed injection unit control part 144 measures the second detection time T2 from when the second detection part 47 detects the syringe holding part 41 to when the first detection part 46 detects the needle 5014. As a result, the mixed injection unit control part 144 can obtain the tip position of the needle 5014 of the syringe 501 actually used in the mixed injection process when the syringe holding part 41 in a state where the syringe 501 actually used in the mixed injection process is held is detected by the second detection part 47 from (second detection time T2-first detection time T1) x predetermined speed V and the tip position of the needle of the jig 601 stored in advance in the memory part 200.

[0079] [Specific configuration of the second conveying section] 8 is a diagram showing an example of the configuration of the second transport unit 120. The second transport unit 120 is a member that removes an infusion container 503 from the infusion shelf 30 in order to inject a medicine into the infusion container 503 indicated in the preparation / administration data, for example. The second transport unit 120 includes an adsorption unit 121 and a third reading unit 122 (reading unit).

[0080] The suction part 121 is a member that suctions the body part 5031 of the infusion container 503. The suction part 121 is an example of a holding member that holds the infusion container 503, and as long as the second transport unit 120 can hold the infusion container 503, the holding member does not have to be the suction part 121. The second transport control unit 145 detaches the infusion container 503 by controlling the air pressure in the suction part 121.

[0081] In this embodiment, three suction parts 121 are provided along the up-down direction at positions facing the infusion container 503 in the second transporting part 120. The three suction parts 121 include a main suction part 121A and two sub suction parts 121B.

[0082] The main suction part 121A is always used to adsorb the infusion container 503 when the second transport part 120 holds the infusion container 503. The main suction part 121A is provided at a position capable of facing all of the infusion containers 503 of different sizes that can be stored in the co-infusion device 1. The two sub-suction parts 121B adsorb the infusion container 503 together with the main suction part 121A depending on the vertical size of the infusion container 503. Therefore, at least one of the two sub-suction parts 121B may not adsorb the infusion container 503 depending on the size of the infusion container 503.

[0083] The positional relationship between the adsorption location of the infusion container 503 (e.g., the infusion shelf 30 and the mixing unit 40) and the second transporting section 120 is predetermined so that the main adsorption section 121A is always used when the second transporting section 120 holds the infusion container 503.

[0084] The control unit 140 stores the type of the infusion container 503 being transported by the second transport unit 120 in a volatile memory. Therefore, if the power supply of the co-infusion device 1 is turned off due to a power outage or the like while the second transport unit 120 is transporting the infusion container 503, the control unit 140 may not be able to manage the type of the infusion container 503 held by the second transport unit 120. In such a case, in the co-infusion device 1 after the power supply is turned on, the printing and inspection unit 50 affixes a label on which information indicating that the co-infusion process using the infusion container 503 may not have been performed correctly is printed to the infusion container 503 held by the second transport unit 120. The information may be an example of second information different from the first information (described later). In this case, the label is a label showing the second information, and may be affixed at a position that does not overlap with the first label LA11 (see reference numeral 1061 in FIG. 20) like the second label LA12.

[0085] At this time, the label is affixed to an area Ar11 on the second surface SF2 facing the main suction part 121A. The positional relationship between the main suction part 121A and the guide part 56 (described later) of the printing and inspection unit 50 is determined in advance so that the label can be affixed to the area Ar11. The area of ​​the second surface SF2 facing the part that is suctioned by the suction part 121 is less likely to move, allowing the label to be affixed more reliably. The area Ar11 faces the part that is suctioned by any infusion container 503. Therefore, by setting the area Ar11 as the label affixing position, the label can be affixed more reliably regardless of the type of infusion container 503 held by the second transport section 120.

[0086] The label may be attached by a user. At least a part of the label may be attached to the area Ar11. The number of suction parts 121 is not limited to three, and may be one or a number other than three. When a plurality of suction parts 121 are provided, it is sufficient that at least one of them is the main suction part 121A.

[0087] The third reading unit 122 reads first information included in a first label LA11 (see reference numeral 1061 in FIG. 20) affixed to the body 5031 of the infusion container 503. The first label LA11 is a label affixed in advance to the infusion container 503 by a pharmaceutical manufacturer that provides the infusion container 503, and is also referred to as an infusion label. The first information read by the third reading unit 122 is, for example, infusion type information indicating the type of infusion.

[0088] In this embodiment, the third reading unit 122 includes a light receiving unit 1222 that receives light reflected on the surface of the infusion container 503. For example, when the third reading unit 122 includes a light emitting unit 1221 that emits light to the surface of the infusion container 503 stored in the infusion shelf 30, the light receiving unit 1222 may receive the light that is emitted from the light emitting unit 1221 and reflected on the surface of the infusion container 503. The third reading unit 122 reads the first information based on a change in the amount of light received by the light receiving unit 1222. When the first information is included in a barcode, the third reading unit 122 may be realized by a barcode reader.

[0089] In this embodiment, the third reading unit 122 functions as a recognition unit that recognizes the orientation of the first surface SF1 of the infusion container 503. Specifically, the third reading unit 122 recognizes the orientation of the first surface SF1 based on a change in the amount of light received by the light receiving unit 1222. In this case, the third reading unit 122 can recognize the orientation of the first surface SF1 by functioning as an optical member. In this embodiment, when the third reading unit 122 can read the first information, the control unit 140 recognizes that the orientation of the first surface SF1 is a predetermined direction. In this embodiment, the predetermined direction is the back direction of the co-infusion device 1 (the direction in which the third reading unit 122 is located as viewed from the infusion shelf 30).

[0090] When the second transport unit 120 removes the infusion container 503 from the infusion shelf 30, the third reading unit 122 reads the first information included in the first label LA11 from the infusion container 503 stored on the infusion shelf 30. In this embodiment, the first label LA11 is attached to the first surface SF1. Therefore, when the second transport unit 120 removes the infusion container 503 from the infusion shelf 30, if the infusion container 503 is stored on the infusion shelf 30 so that the second transport unit 120 and the first label LA11 face each other, the third reading unit 122 can recognize that the orientation of the first surface SF1 is toward the back of the co-infusion device 1.

[0091] In addition, the control unit 140 judges whether the type of infusion indicated by the first information is the same as the type of infusion indicated in the preparation / administration data as a result of the third reading unit 122 reading the first information. When the control unit 140 judges that the two types are the same, it transports the infusion container 503 to the mixing unit 40 or the like without notifying an error indicating that they are not the same. On the other hand, when the control unit 140 judges that the two types are not the same, it may notify an error, or may place the infusion container 503 on the infusion receiving shelf 60 and take out another infusion container 503 from the infusion shelf 30.

[0092] (Example 1 of modification of the reading position of the first information) The reading position of the first information by the third reading unit 122 is set in advance for each type of infusion container 503 to be read by the third reading unit 122. The reading position is set in advance, for example, based on the position where the first information is attached on the first surface SF1 and the storage position (filling position) of the infusion container 503 on the infusion shelf 30. The storage position of the infusion container 503 is the position of the infusion container 503 at the take-out position where the second transport unit 120 takes out the infusion container 503 from the infusion shelf 30. The storage position of the infusion container 503 is the position of the infusion container 503 at the take-out position on the infusion shelf 30 where the infusion container 503 to be taken out is stored among the multiple infusion shelves 30. The take-out position is a position corresponding to the rear end 362 (see FIG. 13) of the rail portion 36 of the infusion shelf 30.

[0093] The information indicating the reading position is stored in the memory unit 200. Therefore, by referring to the memory unit 200, the second transport control unit 145 can move the second transport unit 120 to a position where the second transport unit 120 faces the infusion container 503 to be removed and reads the first information attached to the infusion container 503.

[0094] When the second transport unit 120 removes the infusion container 503 from the infusion shelf 30, the second transport control unit 145 reads the first information, setting the above-mentioned reading position (registered position) as the initial reading position. If the third reading unit 122 is unable to read the first information at the initial reading position, the second transport control unit 145 moves the reading position. In this embodiment, the reading position is moved by moving the second transport unit 120. The direction in which the reading position is moved and the distance by which the reading position is moved in each movement can be set arbitrarily.

[0095] The second conveyance control unit 145 executes reading by the third reading unit 122 while moving the reading position. Then, the second conveyance control unit 145 specifies the range in which the third reading unit 122 was able to read the first information, and rewrites the information indicating the reading position stored in the memory unit 200 to information indicating the center position of the range.

[0096] Therefore, in the subsequent processing, when reading the first information from the infusion container 503 containing the same type of infusion as that contained in the infusion container 503 whose reading position has been changed, the third reading unit 122 executes the reading process of the first information using the changed reading position. Therefore, even if the position of the first information on the infusion container 503 is changed due to a change in the layout of the first label LA11 attached to the infusion container 503, for example, the reading position can be changed to match the changed position of the first information.

[0097] (Example 2 of modification of the reading position of the first information) If the third reading unit 122 is unable to read the first information at the preset reading position, the second conveying control unit 145 may control the second conveying unit 120 (orientation change unit) to change the orientation of the third reading unit 122.

[0098] In the infusion shelf 30, the infusion container 503 is stored in a state of being suspended from the rail portion 36. Therefore, there is a risk that the infusion container 503 rotates about an axis parallel to the vertical direction. Due to this rotation, there is a risk that the first surface SF1 does not face the back direction of the co-infusion device 1 at the above-mentioned removal position. Therefore, there is a risk that the position of the first information is shifted in the left-right direction, and therefore the third reading unit 122 cannot read the first information at a preset reading position (initial reading position).

[0099] As described above, by changing the orientation of the third reading unit 122, the possibility that the third reading unit 122 can read the first information can be increased even when the first surface SF1 does not face the back of the co-infusion apparatus 1. For example, the orientation of the third reading unit 122 may be changed along the width direction of the infusion container 503 from which the first information is read. In this embodiment, the width direction of the infusion container 503 is the left-right direction of the co-infusion apparatus 1.

[0100] 9 is a diagram for explaining the reading position of the first information. In this embodiment, when the third reading unit 122 cannot read the first information at the initial reading position, the second transport unit 120 moves in the left-right direction as shown by reference numeral 1021 in FIG. 9, thereby moving the third reading unit 122 in the width direction of the infusion container 503. This allows the second transport unit 120 to move the reading position in the width direction of the infusion container 503.

[0101] 9, the third reading unit 122 may be rotated about an axis parallel to the vertical direction as a rotation axis to move the reading position in the width direction of the infusion container 503. The third reading unit 122 may be rotated about the rotation axis by the operation of the second transport unit 120, or the second transport unit 120 may have a mechanism for rotating the third reading unit 122 about the rotation axis.

[0102] Furthermore, when the third reading unit 122 is unable to read the first information even if the orientation of the third reading unit 122 is changed along the width direction of the infusion container 503, the second transport control unit 145 may change the orientation along the height direction of the infusion container 503 from which the first information is to be read. In this embodiment, the height direction of the infusion container 503 is the up-down direction of the co-infusion device 1. This can further increase the possibility that the third reading unit 122 can read the first information.

[0103] In this embodiment, as indicated by reference numeral 1023 in Fig. 9, the second transporting unit 120 moves in the up-down direction, thereby moving the third reading unit 122 in the height direction of the infusion container 503. This allows the second transporting unit 120 to move the reading position in the height direction of the infusion container 503.

[0104] In addition, the second conveyance control unit 145 may change the orientation of the third reading unit 122 so that the reading position faces the first information. This can further increase the possibility that the third reading unit 122 can read the first information.

[0105] In this embodiment, as shown by reference numeral 1024 in Fig. 9, when viewed from above, the third reading unit 122 moves in an approximately arc shape around the position where the neck of the infusion container 503 is located at the removal position. This allows the second transport unit 120 to move the reading position so as to face the first information. The third reading unit 122 may be moved in an approximately arc shape by the operation of the second transport unit 120, or the second transport unit 120 may have a mechanism for moving the third reading unit 122 in an approximately arc shape.

[0106] [Specific configuration of syringe shelf] Fig. 10 is a perspective view showing an example of the overall configuration of the syringe shelf 10 and the vial shelf 20. Reference numeral 1025 in Fig. 11 is a diagram showing an example of the configuration of one syringe shelf 10 and one vial shelf 20 when viewed from the first transport section 110 side. Reference numeral 1026 in Fig. 11 is a diagram for explaining the vial shelf 20.

[0107] As shown in Fig. 10, the syringe shelf 10 comprises a plurality of instrument holding sections 11, an instrument transport section 12, an object detection section 13, and a syringe detection section 14. Note that an instrument holding section 11 is also attached to the attachment section 1211 of the instrument transport section 12 shown in Fig. 10, but is not shown in the figure.

[0108] Prior to a mixed injection process, a user loads syringes 501 into the syringe shelf 10. The syringes 501 are loaded into the syringe shelf 10 with needle caps 5016 attached to the needles 5014.

[0109] In this embodiment, a plurality of holes 172 are formed in the plate-like member 171 that defines each syringe shelf 10. This allows, for example, air purified by the air purifying unit 130 (see FIG. 2) to flow efficiently from the top to the bottom of the co-infusion device 1.

[0110] The multiple instrument holding parts 11 are members capable of holding a syringe 501. In this embodiment, one syringe 501 is held by one instrument holding part 11, but multiple syringes 501 may be held by one instrument holding part 11. In this embodiment, the instrument holding part 11 comprises free rollers 1111 and an instrument clamping part 1112, as shown in FIG.

[0111] The instrument clamping part 1112 clamps the syringe 501. In this embodiment, the instrument clamping part 1112 clamps the flange 5013 of the syringe 501. The instrument clamping part 1112 is provided at a height such that the syringe 501 does not touch the plate-shaped member 171 when the syringe 501 is held by the instrument holding part 11.

[0112] The pair of instrument clamping parts 1112 are biased in directions approaching each other so as to be able to clamp the syringe 501. In this embodiment, the instrument clamping parts 1112 are spaced apart to an extent smaller than the width of the flange 5013 when the flange 5013 is not clamped. When the flange 5013 is inserted between the instrument clamping parts 1112, the instrument clamping parts 1112 move in accordance with the shape of the flange 5013. This enables the instrument clamping parts 1112 to clamp the syringe 501.

[0113] A free roller 1111, which has a rotation axis extending in the vertical direction and is rotatable on the XY plane, is provided below the tip of the instrument clamping part 1112. The free roller 1111 holds the vicinity of the flange 5013 of the syringe 5011 clamped by the instrument clamping part 1112.

[0114] The instrument transporting section 12 is a member that transports at least one of the multiple instrument holding sections 11 to the working area Ar1. In this embodiment, the instrument transporting section 12 is an endless rotating member (rotating belt) to which the multiple instrument holding sections 11 are connected. Therefore, in this embodiment, the instrument transporting section 12 transports the instrument holding sections 11 one by one to the working area Ar1. However, the instrument transporting section 12 may be a transporting section that transports multiple instrument holding sections 11 to the working area Ar1 at one time.

[0115] The working area Ar1 is an area where the user causes at least one of the multiple instrument holding parts 11 to hold the syringe 501. The working area Ar1 is also an area where the user removes the syringe 501 held in at least one of the multiple instrument holding parts 11. In this embodiment, the working area Ar1 is an area where the user causes one instrument holding part 11 to hold the syringe 501, and where the user removes the syringe 501 held in one instrument holding part 11.

[0116] The working area Ar1 may function only as an area where the user causes at least one of the plurality of instrument holding parts 11 to hold the syringe 501. In this case, the area where the user removes the syringe 501 held in the instrument holding part 11 may be provided at a position separate from the working area Ar1. The working area Ar1 may function only as an area where the user removes the syringe 501 held in the instrument holding part 11. In this case, the area where the user causes the syringe 501 to be held in the instrument holding part 11 may be provided at a position separate from the working area Ar1.

[0117] In this embodiment, the instrument transporting unit 12 transports another instrument holding unit 11 in place of the instrument holding unit 11 located in the working area Ar1 when the object detection unit 13 detects an object (e.g., the user's hand) and then stops detecting the object as a trigger. In this case, the instrument transporting unit 12 transports another instrument holding unit 11 to the working area Ar1 when the user inserts his / her hand into the working area Ar1, the user causes the instrument holding unit 11 to hold the syringe 501, and then the user's hand leaves the working area Ar1. The instrument transporting unit 12 may transport another instrument holding unit 11 to the working area Ar1 when the syringe detection unit 14 detects the syringe 501 held by the instrument holding unit 11 or when the syringe detection unit 14 can no longer detect the syringe 501 held by the instrument holding unit 11, in addition to detecting the user's action.

[0118] In response to a transport instruction from the user, the instrument transport section 12 may transport another instrument holder 11 instead of the instrument holder 11 located in the working area Ar1. In this case, the syringe transport control section 141 may receive the transport instruction from the user via the touch panel 80, for example.

[0119] The instrument transport part 12 changes the instrument holding part 11 located in the working area Ar1, for example by rotating counterclockwise. By this transport operation, in place of the instrument holding part 11 holding the syringe 501 in the working area Ar1, another instrument holding part 11 not holding the syringe 501 can be transported to the working area Ar1.

[0120] The object detection unit 13 is a member that detects an object inserted into the working area Ar1. In this embodiment, the object detection unit 13 detects the user's hand or arm inserted in the working area Ar1. The syringe detection unit 14 is a member that detects the syringe 501 held in the instrument holding unit 11 located in the working area Ar1. In this embodiment, the syringe detection unit 14 detects the syringe 5011 when the syringe 501 is held in the instrument holding unit 11.

[0121] [Specific configuration of vial shelf] As indicated by reference numeral 1025 in Figures 10 and 11, the vial shelf 20 comprises a plurality of instrument holding parts 21, an instrument transport part 22, an object detection part 23, and a vial detection part 24. Also, as indicated by reference numeral 1025 in Figure 11, the vial shelf 20 comprises a first reading part 25 (reading part) and a roller driving part 26. Note that an instrument holding part 21 is also attached to the mounting part 221 of the instrument transport part 22 shown in Figure 10, but this is not shown in the figure.

[0122] Prior to the mixed injection process, the vial shelf 20 is filled with vials 502 by a user. The vials 502 are provided with rubber stoppers 5021 (see FIG. 5) that close the openings and lids that cover the rubber stoppers 5021. The vials 502 are filled in the vial shelf 20 with the lids removed. Similarly to the syringe shelf 10, a plurality of holes 172 are formed in the plate-like member 171 that defines each vial shelf 20.

[0123] The instrument holding part 21 is a member capable of holding a vial 502. In this embodiment, one instrument holding part 21 holds one vial 502, but one instrument holding part 21 may hold a plurality of vials 502.

[0124] In this embodiment, as shown in FIG. 11, the object holding part 21 includes free rollers 211, an object clamping part 212, a driving roller 213, and a first magnet gear 214.

[0125] The instrument clamping part 212 clamps the vial 502. In this embodiment, the instrument clamping part 212 clamps the neck part of the vial 502. The instrument clamping part 212 is provided at a height such that the vial 502 does not touch the plate-like member 171 when the vial 502 is held by the instrument holding part 21.

[0126] The pair of instrument clamping parts 212 are biased in directions approaching each other so as to be able to clamp the vial 502. In this embodiment, the instrument clamping parts 212 are spaced apart to an extent smaller than the width of the neck of the vial 502 when the neck is not being clamped. When the neck is inserted between the instrument clamping parts 212, the instrument clamping parts 212 move in accordance with the shape of the neck. This enables the instrument clamping parts 212 to clamp the vial 502.

[0127] A free roller 211 having a vertically extending rotation axis and rotatable on the XY plane is provided at the tip of the instrument clamping part 212. As indicated by reference numeral 1026 in Fig. 11, the free roller 211 holds the vial 502 by supporting the neck of the vial 502 at three points together with a drive roller 213 provided on the side on which the instrument clamping part 212 is axially supported and at a position opposite the center of the free roller 211. When the drive roller 213 rotates while holding the vial 502, the vial 502 also rotates. In conjunction with this rotation, the free roller 211 also rotates.

[0128] A first magnet gear 214 is provided on the upper part of the driving roller 213. The driving roller 213 and the first magnet gear 214 are connected to a common rotation shaft extending in the vertical direction and are rotatable on the XY plane. When the first magnet gear 214 rotates in accordance with the rotation of the second magnet gear 261 provided in the roller driving unit 26, the driving roller 213 also rotates.

[0129] The instrument transporting section 22 is a member that transports at least one of the multiple instrument holding sections 21 to the working area Ar2. In this embodiment, the instrument transporting section 22 is an endless rotating member to which the multiple instrument holding sections 21 are connected. Therefore, in this embodiment, the instrument transporting section 22 transports the instrument holding sections 21 one by one to the working area Ar2. However, the instrument transporting section 22 may be a transporting section that transports multiple instrument holding sections 21 to the working area Ar2 at one time.

[0130] Like the working area Ar1, the working area Ar2 is an area where the user causes at least one of the multiple equipment holders 21 to hold the vial 502. Also, the working area Ar2 is an area where the user removes the vial 502 held in at least one of the multiple equipment holders 21. Also, like the working area Ar1, the working area Ar2 may be an area that functions only as an area for holding the vial 502, or an area that functions only as an area for removing the vial 502.

[0131] In this embodiment, the instrument transporting section 22 has the same function as the instrument transporting section 12. Specifically, the instrument transporting section 22 transports another instrument holding section 21 in place of the instrument holding section 21 located in the working area Ar2 when the object detection section 23 detects an object (e.g., the user's hand) and then stops detecting the object, which is a trigger. The instrument transporting section 12 may transport another instrument holding section 11 to the working area Ar2 when the vial detection section 24 detects the vial 502 held in the instrument holding section 21 or when the vial detection section 24 can no longer detect the vial 502 held in the instrument holding section 21, in addition to detecting the user's movement. The instrument transporting section 12 changes the instrument holding section 21 located in the working area Ar2 by, for example, rotating counterclockwise.

[0132] Furthermore, like the syringe transport control unit 141, the vial transport control unit 142 may transport another instrument holding unit 21 in place of the instrument holding unit 21 located in the working area Ar2, for example, in response to a transport instruction from the user.

[0133] The object detection unit 23 is a member that detects an object inserted into the working area Ar2. In this embodiment, the object detection unit 23 detects the user's hand or arm inserted into the working area Ar2. The vial detection unit 24 detects the vial 502 held in the instrument holder 21 located in the working area Ar2.

[0134] The first reading unit 25 is a member that reads type information indicating the type of drug contained in the vial 502, which is indicated on the surface of the vial 502, in a part of the transport path along which the instrument transport unit 22 transports the multiple instrument holders 21. The vial 502 may be provided with a barcode on which the type information is recorded. In this case, the first reading unit 25 may be a barcode reader. As indicated by reference numeral 1025 in FIG. 11, the first reading unit 25 is disposed at a position where it can read the barcode of the vial 502 transported to the removal position PO11. The removal position PO11 is a position where the first transport unit 110 removes the vial 502.

[0135] The roller driving unit 26 is a motor that rotates the second magnet gear 261 attached to the roller driving unit 26 in order to rotate the driving roller 213 of the instrument holding unit 21. The rotation shaft of the roller driving unit 26 extends in the Y-axis direction, and the second magnet gear 261 is attached to the rotation shaft. When the vial transport control unit 142 drives the roller driving unit 26, the second magnet gear 261 also rotates. The first magnet gear 214 rotates in conjunction with the rotation of the second magnet gear 261. The driving roller 213 connected to the same rotation shaft as the first magnet gear 214 rotates in conjunction with the rotation of the first magnet gear 214, and the vial 502 in contact with the driving roller 213 rotates. By rotating the vial 502 in this way, the first reading unit 25 can read the barcode no matter where the barcode is attached on the surface of the vial 502.

[0136] (Transportation processing of equipment holding section) The vial transport control section 142 controls the instrument transport section 22 to transport the instrument holders 21 holding the vials 502 to be removed one by one to the removal position PO11.

[0137] The memory unit 200 stores, in association with one another, information identifying each equipment holding section 21, information indicating the type of drug contained in the vial 502 held in each equipment holding section 21, and information indicating the transport position of each equipment holding section 21, for example.

[0138] The preparation and administration data may be transmitted from a host system (not shown) of the co-infusion device 1 to the co-infusion device 1 for each co-infusion process. In this case, for example, when the co-infusion unit 40 completes a co-infusion process, the control unit 140 requests the host system to transmit preparation and administration data for the co-infusion unit 40 to execute the next co-infusion process. When the control unit 140 receives the preparation and administration data, it starts the next co-infusion process. Therefore, the preparation and administration data becomes a co-infusion instruction (injection instruction) for executing the co-infusion process in the co-infusion unit 40.

[0139] When the vial transport control unit 142 receives the preparation / administration data, it refers to the memory unit 200 to identify the vial 502 to be removed, and controls the instrument transport unit 22 to transport the vial 502 to the removal position PO11.

[0140] Specifically, when the vial transport control unit 142 receives preparation / administration data after the first transport unit 110 removes the vial 502 from the instrument holding unit 21, the vial transport control unit 142 transports the instrument holding unit 21 holding the vial 502 to be used in the next mixed injection process to the removal position PO11. However, even if the vial transport control unit 142 does not receive preparation / administration data after the first transport unit 110 removes the vial 502, the vial transport control unit 142 may transport the instrument holding unit 21 holding the vial 502 containing the same type of drug as the vial 502 to the removal position PO11.

[0141] For example, the vial transport control unit 142 refers to the memory unit 200 to determine whether or not there is an equipment holding unit 21 that holds a vial 502 containing the same type of drug as the vial 502 to be removed by the first transport unit 110. When the vial transport control unit 142 determines that there is an equipment holding unit 21 that holds the vial 502, it transports the equipment holding unit 21 to the removal position PO11 regardless of whether preparation / administration data has been received.

[0142] As a result, when the first transport control unit 143 receives the preparation / administration data, it can take out the vial 502 from the take-out position PO11 without waiting for the vial 502 to be transported to the take-out position PO11. Therefore, the control unit 140 can quickly start the mixed injection process based on the preparation / administration data to be sent to the mixed injection device 1 in the future, so that it is possible to shorten the overall time required for the mixed injection process. Note that the mixed injection device 1 may execute such a process when it allows continuous mixed injection processes using the same type of drug by reusing the syringe 501 in order to save the number of syringes 501 used.

[0143] (Recovery of vials) FIG. 12 is a flowchart showing an example of the flow of processing by the control unit 140 when the control unit 140 receives an instruction to collect the vial 502.

[0144] The instrument transport section 22 may transport the instrument holder 21 holding the vial 502 designated as the object to be collected to the working area Ar2 in response to an instruction to collect the vial 502. This allows the user to easily collect the vial 502 stored in the vial shelf 20.

[0145] In this embodiment, it is assumed that the order in which the vial shelves 20 go into the collection mode for collecting the vials 502 held in the instrument holding section 21 is preset for each of the multiple vial shelves 20. Information indicating the order is stored in the memory section 200 in association with each vial shelf 20. Information regarding which vials 502 are designated as collection targets is also stored in the memory section 200.

[0146] For example, when the first reading unit 25 cannot read type information from the vial 502, the control unit 140 designates the vial 502 as a collection target. In this case, when the equipment transport unit 22 receives the collection instruction, it transports the equipment holding unit 21 holding the vial 502 whose type information cannot be read to the working area Ar2. The co-infusion device 1 cannot use the medicine contained in the vial 502 whose type information cannot be read for the co-infusion process. Therefore, by transporting the vial 502 based on the above designation, the user can collect the vial 502 that cannot be used in the co-infusion process.

[0147] Furthermore, the control unit 140 designates, for example, the vial 502 designated by the user via the touch panel 80 as the collection target. In this case, when the collection instruction is received, the instrument transport unit 22 transports the instrument holding unit 21 holding the vial 502 designated by the user to the working area Ar2. Thus, the user can collect the vial 502 designated by the user. Note that the collection instruction may include information on the vial 502 designated by the user as the collection target.

[0148] 12, the vial transport control unit 142 determines whether the above-mentioned collection instruction has been received, for example, via the touch panel 80 (S11). The vial transport control unit 142 waits for the receipt of the above-mentioned collection instruction until the above-mentioned collection instruction is received (if NO in S11).

[0149] When the vial transport control unit 142 determines that the recovery instruction has been received (YES in S11), it selects the vial shelf 20 for which the smallest order in the recovery mode orders is set by referring to the memory unit 200 (S12). The vial transport control unit 142 determines whether the status of the selected vial shelf 20 indicates that the first transport unit 110 (removal unit) is removing the vial 502 (removing the vial 502) (S13).

[0150] The above status is managed for each vial shelf 20 in the memory unit 200. When a vial 502 held in a vial shelf 20 becomes a target for removal, the control unit 140 sets the status of the vial shelf 20 to "removing the vial 502". On the other hand, when the control unit 140 determines that the first transport unit 110 has removed the vial 502 from the vial shelf 20, it sets the status of the vial shelf 20 to "not removing the vial 502". For example, when the control unit 140 determines that the first transport unit 110 is holding the vial 502 and has moved a certain distance from the vial shelf 20, it sets the status of the vial shelf 20 to "not removing the vial 502".

[0151] When the vial transport control unit 142 determines that the status of the vial shelf 20 does not indicate that the vial 502 is being removed (NO in S13), it sets the selected vial shelf 20 to a collection mode. Then, the vial transport control unit 142 determines whether the vial 502 to be collected is present in the selected vial shelf 20 by referring to the memory unit 200 (S14).

[0152] When the vial transport control unit 142 determines that the vial 502 to be collected is present on the selected vial shelf 20 (YES in S14), it controls the instrument transport unit 22 to transport the vial 502 to be collected from the selected vial shelf 20 to the working area Ar2. At this time, the vial transport control unit 142 determines whether the vial 502 to be collected is held in each of the instrument holding units 21. When the vial transport control unit 142 determines that the vial 502 to be collected is held, it controls the instrument transport unit 22 to preferentially transport the instrument holding unit 21 holding the vial 502 that is held earlier in the instrument holding unit 21 to the working area Ar2 (S15). Note that the memory unit 200 stores information indicating the holding order of the vials 502 in association with the positions of the instrument holding units 21.

[0153] The earlier the vial 502 is held, the earlier the expiration date is likely to arrive. Therefore, by preferentially transporting the vial 502 with the earlier holding order to the working area Ar2, the user can preferentially collect the vial 502 that is likely to expire soon.

[0154] For example, consider a case where the user has specified the number of vials 502 to be collected in the collection instruction, and the number of vials 502 containing the drug is equal to or greater than the specified number stored in the vial shelf 20. In this case, the control unit 140 specifies the number of vials 502 specified by the user as the vials 502 to be collected, giving priority to the vials 502 that are held earlier (the ones that are filled earlier in the vial shelf 20). Then, in S15, the vial transport control unit 142 controls the instrument transport unit 22 to transport the number of vials 502 to the working area Ar2. This allows the user to collect the desired number of vials 502, giving priority to the vials 502 that are held earlier.

[0155] The vials 502 for which the user specifies the number to be collected may be vials 502 containing the same type of medicine. If the selected vial shelf 20 does not contain vials 502 that satisfy the above number, the vial transport control unit 142 may take out the remaining vials 502 from another vial shelf 20. If the above number is not specified, the vial transport control unit 142 may transport all of the vials 502 to be collected to the working area Ar2 in any order regardless of the order in which they were held.

[0156] The vial transport control unit 142 judges whether the instrument transport unit 22 has transported all of the vials 502 to be collected to the working area Ar2 in the selected vial shelf 20 (S16). When the vial transport control unit 142 judges that the transport of all of the vials 502 to be collected has not been completed (NO in S16), it executes the process of S15. On the other hand, when the vial transport control unit 142 judges that the transport of all of the vials 502 to be collected has been completed (YES in S16), it judges whether there is another vial shelf 20 that can be selected (S17). When the order of the collection mode set for the vial shelf 20 selected in S12 is not the last order, the vial transport control unit 142 judges that there is another vial shelf 20 that can be selected.

[0157] When the vial transport control unit 142 determines that there is another vial shelf 20 that can be selected (YES in S17), it selects the vial shelf 20 that is set to the next order after the vial shelf 20 selected in S12 (S18) and executes the process of S13. On the other hand, when the vial transport control unit 142 determines that there is no another vial shelf 20 that can be selected (NO in S17), it assumes that the recovery operation of the vials 502 for all vial shelves 20 has been completed, and ends the process flow of FIG.

[0158] In this way, the vial transport control unit 142, in response to the above-mentioned collection instruction, transports the instrument holding unit 21 holding the vial 502 designated as the collection target in the vial shelves 20 whose order of going into collection mode has been set to an arbitrary order, to the working area Ar2. After completing the transportation of the instrument holding unit 21, the vial transport control unit 142 starts transporting the instrument holding unit 21 holding the vial 502 designated as the collection target in the vial shelf 20 set to the next order of the above-mentioned arbitrary order, to the working area Ar2. This allows the user to efficiently collect the vials 502, since the collection operation of the vials 502 can be performed for each vial shelf 20.

[0159] In addition, when the vial transport control unit 142 determines that the status of the selected vial shelf 20 indicates that the vial 502 is being removed (YES in S13), it executes the process of S17. Therefore, when it is the turn of the vial shelf 20 from which the vial 502 is being removed to be set to the recovery mode, the vial transport control unit 142 does not set the vial shelf 20 in question to the recovery mode, but sets the vial shelf 20 set next to the vial shelf 20 in question to the recovery mode. Therefore, the user can recover the vial 502 from the vial shelf 20 set next to the vial shelf 20 set to the recovery mode without waiting for the first transport unit 110 to remove the vial 502. For the vial shelves 20 that were not set to the recovery mode, the vial transport control unit 142 assigns the recovery mode turn to the order next to the vial shelves 20 set to the recovery mode or the last order instead.

[0160] The vial transport control unit 142 also executes the process of S17 when it is determined that the vial 502 to be collected is not present in the selected vial shelf 20 (NO in S14).

[0161] [Configuration of infusion shelf] Fig. 13 is a perspective view showing an example of the configuration of the infusion shelf 30. As shown in Fig. 13, the infusion shelf 30 includes a pusher section 31, a pusher transport section 35, and a rail section 36 (hanging holder section). Also, as shown in Fig. 3, the infusion shelf 30 includes a shutter 37.

[0162] Prior to the mixed injection process, the infusion shelf 30 is filled with infusion containers 503 by the user. Similarly to the syringe shelf 10 and the vial shelf 20, the plate-like member 301 defining each infusion shelf 30 has a plurality of holes 302 formed therein.

[0163] The rail section 36 is a member provided inside the infusion shelf 30 and extending from the infusion side door 34 (see FIG. 1) side toward the back of the co-infusion device 1 (i.e., in the +Y-axis direction). In the rail section 36, the end located on the infusion side door 34 side can be called the door side end 361, and the end located on the back side of the co-infusion device 1 can be called the back side end 362. The infusion container 503 is loaded into the rail section 36 from the door side end 361, and is taken out from the back side end 362 by the second conveying section 120. At least one infusion container 503 can be hung on the rail section 36. In this embodiment, the neck of the infusion container 503 can be hung between a pair of rail sections 36. Specifically, a flange 5034, which is a part of the neck 5033 of the infusion container 503, can be hung between a pair of rail sections 36.

[0164] In this embodiment, each infusion shelf 30 is provided with three rail portions 36. However, the number of rail portions 36 provided on each infusion shelf 30 is not limited to three. In this embodiment, each of the rail portions 36 is filled with the same type of infusion containers 503 (infusion containers having the same type of infusion contained in the infusion container 503 and the same size of the infusion container 503). The infusion containers 503 to be filled are determined for each infusion shelf 30. However, each of the rail portions 36 may be filled with different types of infusion containers 503.

[0165] The pushing unit 31 is a member that can move along the rail portion 36 and pushes the infusion container 503 suspended from the rail portion 36 from the door side end portion 361 to the back side end portion 362. In this embodiment, the pushing unit 31 is connected to the pushing transport portion 35. The pushing transport portion 35 is provided along the rail portion 36. The pushing transport portion 35 can move the pushing unit 31 along the rail portion 36 by operating under the control of the pushing control unit 147. The pushing transport portion 35 may be, for example, an endless rotating member. The size of the pushing unit 31 and the positional relationship between the rail portion 36 and the pushing transport portion 35 are specified so that the infusion container 503 suspended from the rail portion 36 can be pushed in by the movement of the pushing unit 31.

[0166] When the infusion side door 34 is unlocked or open, the pushing unit 31 is located at a position PO31 on the door side end 361 side and does not interfere with the filling (hanging on the rail portion 36) of the infusion container 503. The pushing control unit 147 may move the pushing unit 31 to the position PO31 by controlling the pushing transport unit 35 when, for example, a button 90 (see FIG. 1) on the infusion shelf 30 is pressed (when the infusion side door 34 is unlocked).

[0167] When the infusion side door 34 is locked, the pushing unit 31 pushes the infusion container 503 suspended from the rail unit 36 ​​from the door side end 361 to the back end 362. In this embodiment, when the infusion side door 34 is locked after being closed, the pushing control unit 147 controls the pushing transport unit 35 to move the pushing unit 31 from the position PO31 to the back end 362. The back end 362 of the wall constituting the infusion shelf 30 is provided with a detection unit (not shown) for detecting the infusion container 503 present at the back end 362. The pushing control unit 147 moves the pushing unit 31 toward the back end 362 until the detection unit detects the infusion container 503.

[0168] Also, consider a case where the second transport unit 120 removes an infusion container 503 located at the rear end 362 while multiple infusion containers 503 are suspended from the rail unit 36. After the second transport unit 120 removes the infusion container 503, the pushing unit 31 pushes the remaining infusion containers 503 suspended from the rail unit 36 ​​from the door side end 361 to the rear end 362. In this embodiment, when the second transport unit 120 removes the infusion container 503 located at the rear end 362, the pushing control unit 147 controls the pushing transport unit 35 to move the pushing unit 31 further to the rear end 362.

[0169] The shutter 37 prevents the infusion container 503 located at the rear end 362 from moving in the rear direction (+Y axis direction). The shutter 37 is controlled by the control unit 140 to be movable in the vertical direction. For example, when the infusion side door 34 is closed, the shutter 37 is controlled by the control unit 140 to be located at the rear side of the infusion shelf 30 corresponding to the infusion side door 34. In addition, when the second transport unit 120 removes the infusion container 503, the shutter 37 moves to an infusion shelf 30 other than the infusion shelf 30 in which the infusion container 503 is stored.

[0170] (Specific configuration of the pushing part) Fig. 14 is a diagram showing an example of a specific configuration of the pushing part 31, where reference numeral 1031 is a perspective view of the pushing part 31, and reference numeral 1032 is a diagram showing the positional relationship between the pushing part 31 and the infusion container 503. Reference numeral 1032 in Fig. 14 is a view seen from below.

[0171] In this embodiment, as shown by reference numeral 1031 in Fig. 14, the pushing unit 31 includes a connection part 311 connected to the pushing and conveying unit 35, and a contact part 312 attached to the connection part 311 and in contact with the body part 5031 of the infusion container 503. The contact part 312 is a rotating member that can rotate around a rotation axis Az extending in the vertical direction. The contact part 312 rotates when it comes into contact with the infusion container 503 due to the movement of the pushing unit 31.

[0172] As shown by the reference numeral 1032 in Fig. 14, a case will be considered in which the depth direction (predetermined direction) D1 of the co-infusion device 1 is different from the direction D2 in which the first surface SF1 of the infusion container 503 faces. In this case, when the pusher 31 moves in the depth direction D1 with the contact portion 312 in contact with the infusion container 503, the rotation of the contact portion 312 rotates the infusion container 503 in the opposite direction to the rotation direction of the contact portion 312, with the vertical axis passing through the neck portion 5033 as the rotation axis. As a result, the infusion container 503 is suspended from the rail portion 36 with the direction D2 in which the first surface SF1 faces substantially coinciding with the depth direction D1.

[0173] Therefore, by providing the contact portion 312, the rail portion 36 can hold the infusion container 503 with the infusion container 503 facing a predetermined direction in response to the pushing operation of the pushing portion 31. This reduces the possibility of failure of the second transport portion 120 to remove the infusion container 503 (suction of the infusion container 503) at the rear end portion 362 and failure of the third reading portion 122 to read the first information.

[0174] The contact portion 312 does not have to have a rotation function. The push-in portion 31 only needs to have a portion that contacts the body portion 5031 when the infusion container 503 is pushed in, and may be, for example, flat. Even in this case, the orientation of the infusion container 503 can be changed so that the direction D2 in which the first surface SF1 faces is approximately aligned with the depth direction D1.

[0175] Therefore, if the pushing part 31 is configured to push the infusion container 503 by contacting the body part 5031 of the infusion container 503 suspended from the rail part 36, the infusion container 503 can be hung from the rail part 36 with the infusion container 503 facing a predetermined direction. In order to achieve this effect, the position where the pushing part 31 comes into contact with the infusion container 503 (the position where the infusion container 503 is pushed in) may be a part below the part supported by the rail part 36, for example, a position below the shoulder part 5032 of the infusion container 503.

[0176] (Falling prevention part) 15 is a side view showing an example of the pushing-in transport unit 35. The pushing-in transport unit 35 is provided with a fall-prevention unit 38 that prevents the infusion container 503 from falling off from the rear end 362. In this embodiment, the pushing-in transport unit 35 is an endless rotating member. Therefore, the pushing unit 31 and the fall-prevention unit 38 move in conjunction with each other.

[0177] 15, when the pushing part 31 is located at the position PO31, the fall-off prevention part 38 is located at the position PO32 directly above the rail part 36 at the rear end part 362. In this state, the user can load the infusion shelf 30 with the infusion container 503. Therefore, when the infusion shelf 30 is loaded with the infusion container 503, the fall-off prevention part 38 is located at the position PO32, thereby preventing the infusion container 503 from falling off from the rear end part 362.

[0178] 15, when the pushing part 31 is located at a position PO33 where it can start pushing the infusion container 503, the falling-off prevention part 38 is located at a position PO34 on the opposite side to the position PO32 across the pushing transport part 35 at the rear end 362. Therefore, when the pushing part 31 moves in the front-rear direction (±Y-axis direction) along the rail part 36, the falling-off prevention part 38 moves in the space above the pushing transport part 35.

[0179] The fall-off prevention part 38 only needs to have a size that allows it to come into contact with the infusion container 503 suspended from the rail part 36 when it is positioned on the rail part 36 side. In this embodiment, the fall-off prevention part 38 has a size that allows it to come into contact with a part of the neck part 5033 of the infusion container 503 suspended from the rail part 36 (the head part of the infusion container 503) without coming into contact with the rail part 36 when it is positioned on the rail part 36 side.

[0180] In this way, the vertical dimension H38 of the fall-off prevention portion 38 is shorter than the vertical dimension H31 of the push-in portion 31. As a result, even when the fall-off prevention portion 38 is provided, the space above the push-in transport portion 35, through which the fall-off prevention portion 38 moves, can be designed to be relatively small.

[0181] The memory unit 200 stores the dimension between the first surface SF1 and the second surface SF2 for each infusion container 503. The control unit 140 can acquire the position of the pusher 31 in the moving range from position PO31 to position PO32 by a known technique. Therefore, the control unit 140 can calculate the number of infusion containers 503 suspended from the rail unit 36 ​​based on the dimension and the position. This allows the control unit 140 to manage the inventory number of infusion containers 503 stored in the infusion shelf 30.

[0182] [Specific configuration of the printing and inspection unit] Fig. 16 is a perspective view showing an example of the overall configuration of the printing and inspection unit 50. Fig. 17 is a perspective view of the printing and inspection unit 50 as viewed from the rear. Fig. 18 is a perspective view showing an example of the internal configuration of the printing and inspection unit 50. Note that the weighing section 52 is omitted from illustration in Figs. 17 and 18. Fig. 16 also shows an example of a state in which the infusion container 503 is positioned in the printing and inspection unit 50 due to suction by the second transport section 120.

[0183] As shown in FIGS. 16 to 18, the printing and inspection unit 50 includes a printing unit 51, a weighing unit 52, a second reading unit 53, an attaching unit 54, and a guide unit 56.

[0184] The printing unit 51 is a member that dispenses a second label LA12 on which second information different from the first information, which is infusion type information, is printed. The second information is information indicating the type of drug to be injected into the infusion container 503. The type of drug indicated by the second information is the drug indicated in the preparation / administration data, and is the drug contained in the vial 502 that the first transport unit 110 transported from the vial shelf 20 to the mixed injection unit 40 in accordance with the preparation / administration data. The printing unit 51 may also dispense an inappropriateness information label on which inappropriateness information is printed.

[0185] The printing and inspection unit control unit 148 inspects the infusion container 503 after the drug is injected. Inspection in this embodiment includes determining whether the amount of drug injected into the infusion container 503 corresponds to the prescribed amount indicated in the preparation and administration data, or whether the amount of infusion withdrawn from the infusion container 503 corresponds to the withdrawn amount indicated in the preparation and administration data.

[0186] Furthermore, the printing and inspection unit control unit 148 judges whether or not an appropriate second label LA12 is affixed to the infusion container 503 after drug injection based on the reading result of the second reading unit 53. The printing and inspection unit control unit 148 judges whether the drug indicated by the second information read from the second label LA12 by the second reading unit 53 is the drug injected into the infusion container 503 from which the second information was read (whether the drug is indicated in the preparation and administration data as the drug to be injected into the infusion container 503).

[0187] When the printing and inspection unit control unit 148 judges the inspection result to be appropriate, the second transport unit 120 dispenses the infusion container 503 to which the second label LA12 is affixed, to the infusion receiving shelf 60. On the other hand, when the printing and inspection unit control unit 148 judges the inspection result to be inappropriate, the printing unit 51 dispenses an inappropriate information label. The inappropriate information may be information indicating that the weight measured by the weighing unit 52 is inappropriate, and / or information indicating that the reading result of the second reading unit 53 is not the drug indicated in the preparation and administration data. The second transport unit 120 dispenses the infusion container 503 to which the inappropriate information label is affixed in addition to the second label LA12, to the infusion receiving shelf 60. The inappropriate information may be an example of second information different from the first information.

[0188] The measuring unit 52 measures the weight of the infusion container 503 before and after the drug injection. In this embodiment, as shown in FIG. 16, the measuring unit 52 includes a first locking unit 521 that locks the neck of the infusion container 503. The second transport unit 120 locks the neck of the infusion container 503 to the first locking unit 521, so that the measuring unit 52 can measure the weight of the infusion container 503. The measuring unit 52 is, for example, a load cell. The pair of first locking units 521 are biased by a spring (not shown) in a direction to approach each other so that the pair of first locking units 521 can clamp the neck of the infusion container 503. The closest distance between the pair of first locking units 521 is set to the distance at which the pair of first locking units 521 can lock the thinnest neck of the infusion container 503.

[0189] When the drug contained in the vial 502 is a liquid, the measuring unit 52 measures the weight of the infusion container 503 before the drug is injected and the weight of the infusion container 503 after the drug is injected.

[0190] In this case, first, the second transport unit 120 takes out the infusion container 503 from the infusion shelf 30 and transports it to the weighing unit 52. After the weighing unit 52 weighs the infusion container 503 (after the first weighing), the second transport unit 120 transports the infusion container 503 to the mixing unit 40. After the mixing unit 40 performs the mixing process, the second transport unit 120 transports the infusion container 503 to the weighing unit 52. After the weighing unit 52 weighs the infusion container 503 (after the second weighing), the second transport unit 120 transports the infusion container 503 to the affixing position PO50 (see FIG. 18) where the second label LA12, or the second label LA12 and the inappropriate information label, are affixed. Then, the printing and inspection unit 50 attaches the second label LA12, or the second label LA12 and the inappropriate information label, to the infusion container 503 according to the measurement result of the weighing section 52. The printing and inspection unit control section 148 inspects whether the amount of the drug injected into the infusion container 503 corresponds to the prescribed amount indicated in the preparation and administration data, based on the difference between the first and second weighing results.

[0191] By attaching a label to the infusion container 503 after weighing, the weighing unit 52 can weigh the infusion container 503 without a label attached for both the first and second weighings. For example, if the weighing unit 52 performs a second weighing after a label is attached to the infusion container 503, the weight of the infusion container 503 increases by the weight of the label at the time of the second weighing. This may cause the printing and inspection unit control unit 148 to be unable to perform an accurate inspection. As described above, by performing two weighings without a label attached, the printing and inspection unit control unit 148 can perform an accurate inspection.

[0192] However, when using a label that is relatively light in weight and does not greatly affect the inspection result, the label may be affixed to the infusion container 503 before the second weighing. The printing / inspection unit control unit 148 may print the second label LA12 at any time. For example, the second label LA12 may be printed before the infusion container 503 is removed from the infusion shelf 30.

[0193] When the drug contained in the vial 502 is solid, the second transport unit 120 first takes out the infusion container 503 from the infusion shelf 30 and transports it to the measuring unit 52. After the measuring unit 52 measures the weight of the infusion container 503 (after the first measurement), the second transport unit 120 transports the infusion container 503 to the mixing and infusion unit 40. The mixing and infusion unit 40 extracts a certain amount of infusion from the infusion container 503 and injects it into the vial 502 in order to dissolve the solid drug. The second transport unit 120 transports the infusion container 503 from which a certain amount of infusion has been extracted to the measuring unit 52. After the measuring unit 52 measures the weight of the infusion container 503 (after the second measurement), the second transport unit 120 transports the infusion container 503 to the mixing and infusion unit 40.

[0194] After the mixing unit 40 injects the liquid medicine into the infusion container 503, the second transport unit 120 transports the infusion container 503 to the measuring unit 52. After the measuring unit 52 weighs the infusion container 503 (after the third weighing), it transports the infusion container 503 to the attachment position PO50 where the second label LA12, or the second label LA12 and the unsuitable information label, are attached. Then, the printing and inspection unit 50 attaches the second label LA12, or the second label LA12 and the unsuitable information label, to the infusion container 503 according to the measurement result of the measuring unit 52.

[0195] By attaching a label to the infusion container 503 after measurement, the measuring unit 52 can measure the first to third doses without a label attached. Therefore, the printing and inspection unit control unit 148 can perform accurate inspection, as in the case where the medicine is a liquid.

[0196] The printing and inspection unit control unit 148 inspects whether the amount of the infusion withdrawn from the infusion container 503 corresponds to the amount indicated in the preparation and administration data based on the difference between the first and second measurements. The printing and inspection unit control unit 148 also inspects whether the amount of the drug injected into the infusion container 503 (the amount of the drug injected in liquid form) corresponds to the prescribed amount indicated in the preparation and administration data based on the difference between the second and third measurements.

[0197] In this embodiment, the second locking part 57 is provided at a position opposite to the measuring part 52 across the guide part 56. The second locking part 57 functions as a buffer that temporarily holds the infusion container 503 taken out from the infusion shelf 30 by the second transport part 120. While the infusion container 503 after measurement (referred to as the first infusion container) is being transported to the mixing unit 40, the infusion container 503 (referred to as the second infusion container) to be used in the next mixed infusion process is taken out from the infusion shelf 30, and the weight of the second infusion container is measured by the measuring part 52. Thereafter, the second infusion container is locked to the second locking part 57. After the drug injection into the first infusion container is completed and the measuring part 52 weighs the first infusion container, the second infusion container is transported from the second locking part 57 to the mixing unit 40. This allows the mixed infusion device 1 to efficiently perform the mixed infusion process.

[0198] The second reading unit 53 reads the second label LA12 attached to the infusion container 503 after the medicine is injected. The second reading unit 53 is, for example, a barcode reader.

[0199] The affixing unit 54 affixes the second label LA12 to the infusion container 503 after the drug has been injected. The affixing unit 54 may affix the second label LA12 to the infusion container 503 after the drug has been injected, for example, before the printing and inspection unit control unit 148 outputs the inspection result (preferably after the final weighing of the infusion container 503 and before the output of the inspection result). Thereafter, when the inspection result by the printing and inspection unit control unit 148 is unsuitable, the affixing unit 54 affixes an unsuitable information label to the infusion container 503 after the drug has been injected.

[0200] In this embodiment, the affixing unit 54 includes an adsorption mechanism 541 and a movement mechanism 542, as shown in Fig. 17. The adsorption mechanism 541 adsorbs the second label LA12 and the inappropriate information label dispensed by the printing unit 51, so that the affixing unit 54 can hold the second label LA12 or the inappropriate information label. The movement mechanism 542 moves the adsorption mechanism 541 between a position where the second label LA12 or the inappropriate information label dispensed from the printing unit 51 is adsorbed and an attachment position PO50 where the second label LA12 or the inappropriate information label is attached to the infusion container 503 after the drug injection.

[0201] In addition, the guide portion 56 shown in Figure 18 guides the movement of the second label LA12 or the inappropriate information label to the infusion container 503 after drug injection when the affixing portion 54 affixes the second label LA12 or the inappropriate information label to the infusion container 503 after drug injection.

[0202] In a state where the second label LA12 or the incompatibility information label has been moved to the affixing position PO50, the second transport unit 120 presses the infusion container 503 after drug injection against the guide unit 56 at the affixing position PO50. As a result, the second label LA12 or the incompatibility information label is affixed to the infusion container 503 after drug injection. Therefore, in this embodiment, the second transport unit 120, the affixing unit 54, and the guide unit 56 function as an attachment unit that attaches the second information to the surface of the infusion container 503.

[0203] The printing and inspection unit 50 may have a vacuum pump (not shown) connected to the suction mechanism 541. The printing and inspection unit control section 148 operates the vacuum pump, so that the vacuum pump sucks in air around the suction pad provided in the suction mechanism 541 through the suction pad. This allows the suction mechanism 541 to adsorb the second label LA12 or the improper information label through the suction pad.

[0204] In this embodiment, the second transport unit 120 presses the infusion container 503 after the drug injection against the guide unit 56 (the second label LA12 located at the attachment position PO50), and then the vacuum pump maintains a state in which it is performing a suction operation. Then, while maintaining this state, the moving mechanism 542 moves the suction mechanism 541 in a direction away from the attachment position PO50 (toward the suction position of the second label LA12). This movement allows the suction mechanism 541 (specifically, the suction pad) to be separated from the second label LA12 attached to the infusion container 503 after the drug injection.

[0205] However, when the second conveying unit 120 presses the infusion container 503 against the guide unit 56, the suction mechanism 541 may release the suction of the second label LA12 or the unsuitable information label. In this embodiment, the printing / inspection unit control unit 148 may stop the suction operation of the vacuum pump, so that the suction mechanism 541 releases the suction of the second label LA12 or the unsuitable information label. This release of suction also allows the suction mechanism 541 to be separated from the second label LA12 affixed to the infusion container 503 after drug injection.

[0206] By attaching the second label LA12 to the infusion container 503, information indicating the type of drug to be injected into the infusion container 503 can be displayed on the infusion container 503 into which the drug is to be injected, as second information different from the first information originally attached to the surface of the infusion container 503. Therefore, the co-infusion device 1 and the user can at least determine what type of drug the drug injected into the infusion container 503 is.

[0207] The second transport unit 120, the affixing unit 54, and the guide unit 56 may affix the second label LA12 to the infusion container 503 before the drug is injected. In this case, the co-infusion device 1 and the user can at least determine what type of drug is injected into the infusion container 503. The second transport unit 120, the affixing unit 54, and the guide unit 56 may affix the second label LA12, for example, before the first weighing. In this case, the weighing unit 52 can perform the first to third weighings with the second label LA12 affixed to the infusion container 503, so that the weight of the label does not affect the inspection by the printing and inspection unit control unit 148.

[0208] After the second label LA12 is affixed to the infusion container 503, the second transport unit 120 does not transfer the infusion container 503 to the infusion receiving shelf 60 until the printing and inspection unit control unit 148 outputs the inspection result. If the inspection result by the printing and inspection unit control unit 148 is proper (after the inspection result of proper is output), the second transport unit 120 transfers the infusion container 503 to the infusion receiving shelf 60. On the other hand, if the inspection result by the printing and inspection unit control unit 148 is improper (after the inspection result of improper is output), an improper information label is affixed to the infusion container 503. Thereafter, the second transport unit 120 transfers the infusion container 503 with the improper information label affixed to it to the infusion receiving shelf 60.

[0209] (Example of operation from reading the first information to attaching the second label) Fig. 19 is a diagram showing an example of operations from reading the first information to delivering the infusion container 503 after drug injection to the infusion receiving shelf 60. Reference numerals 1051 to 1054 in Fig. 19 are diagrams for explaining an example of operations from reading the first information to attaching the second label LA12.

[0210] 19, when the second transport unit 120 removes the infusion container 503 suspended from the rail portion 36 at the rear end portion 362, the third reading unit 122 reads the first information from the first label LA11. In this embodiment, when the third reading unit 122 is able to read the first information, it recognizes that the first surface SF1 of the infusion container 503 to which the first label LA11 is affixed faces the rear direction (+Y-axis direction) (predetermined direction).

[0211] When the third reading unit 122 can read the first information, the first surface SF1 is assumed to face the rear, and the mixed injection unit 40 injects the drug into the infusion container 503. When the drug contained in the vial 502 is solid, when the third reading unit 122 can read the first information, the mixed injection unit 40 extracts the drug from the infusion container 503.

[0212] After the medicine is injected into the infusion container 503 in the mixed injection unit 40, the second transport unit 120 transports the infusion container 503 after the medicine is injected to the measuring unit 52. After the measuring unit 52 weighs the infusion container 503, the second transport unit 120 transports the infusion container 503 to a position facing the guide unit 56 (attaching position PO50), as shown by reference numeral 1052 in FIG. 19. Before the infusion container 503 is transported to this position, the printing unit 51 dispenses the second label LA12, and the suction mechanism 541 transports the second label LA12 to the attaching position PO50. However, the second label LA12 may be transported to the attaching position PO50 after the infusion container 503 is transported to the above position.

[0213] As shown by reference numeral 1052 in Fig. 19, when the second label LA12 is located at the attachment position PO50, the second conveying unit 120 moves toward the attachment position PO50 (-Y axis direction). Then, as shown by reference numeral 1053 in Fig. 19, the second conveying unit 120 presses against the guide unit 56 at the attachment position PO50. In this manner, the second conveying unit 120, the attachment unit 54, and the guide unit 56 attach the second label LA12 to the second surface SF2 of the infusion container 503, which is opposite to the first surface SF1.

[0214] In this embodiment, in order to separate the suction mechanism 541 from the second label LA12, in a state in which the second transport unit 120 presses the infusion container 503 after drug injection against the guide unit 56, the moving mechanism 542 moves the suction mechanism 541 while the vacuum pump is still sucking. However, in a state in which the second transport unit 120 presses the infusion container 503 after drug injection against the guide unit 56, the suction operation of the vacuum pump may be stopped, causing the suction mechanism 541 to release the suction.

[0215] 19, the second transport unit 120 moves to a position before the second label LA12 is affixed, thereby making the infusion container 503 ready to be transported to the infusion receiving shelf 60. Operations after the infusion container 503 with the second label LA12 affixed thereto is transported to the infusion receiving shelf 60, as indicated by reference numerals 1055 and 1056 in FIG. 19, will be described later.

[0216] 19, if the third reading unit 122 cannot read the first information, the control unit 140 may determine that the storage state of the infusion container 503 is not a state in which the second label LA12 can be affixed. In this case, the touch panel control unit 149 may notify information indicating that the first information cannot be read from the infusion container 503, or information indicating the location where the infusion container 503 is stored. The third reading unit 122 may continue the operation of the co-infusion device 1 by executing reading of the first information from the infusion container 503 stored in another location.

[0217] Furthermore, it is not necessarily required that the third reading unit 122 recognizes whether the first surface SF1 faces a predetermined direction based on the result of reading the first information (the result of receiving light by the light receiving unit 1222). A member different from the third reading unit 122 may be provided in the co-infusion device 1 as a recognition unit that recognizes whether the first surface SF1 faces a predetermined direction. Furthermore, the recognition unit only needs to be able to recognize the orientation of the first surface SF1, and does not necessarily need to be realized by an optical member.

[0218] (Effects of the above example) As described above, the attachment unit attaches the second label LA12 to the surface of the infusion container 503 at a position that does not overlap with the first information. This allows the co-infusion device 1 to prevent the first information from overlapping with the second information even when attaching the second information, which is different from the first information originally attached to the surface of the infusion container 503, to the surface of the infusion container 503. Therefore, the co-infusion device 1 can avoid the occurrence of a reading failure of the first information due to attaching the second information. In addition, even if the second information is attached to the surface of the infusion container 503, the user can also read the first information.

[0219] The application unit can apply the second information to the surface of the infusion container 503 so as not to overlap with the first information by attaching the second label LA12 to a surface of the infusion container 503 different from the first surface SF1 to which the first information is attached. As described above, in this embodiment, the application unit attaches the second label LA12 to the second surface SF2 opposite to the first surface SF1, so that the second information can be applied to the surface of the infusion container 503 so as not to overlap with the first information.

[0220] The attachment unit attaches the second label LA12 to a surface (e.g., the second surface SF1) different from the first surface SF1 based on the recognition result of the orientation of the first surface SF1 by the recognition unit. Therefore, the second information can be attached to the surface of the infusion container 503 so as not to overlap with the first information. Specifically, when the recognition unit recognizes that the first surface SF1 faces a predetermined direction (e.g., the back direction), the attachment unit attaches the second label LA12 to a surface (e.g., the second surface SF2) facing a direction other than the predetermined direction. This allows the co-infusion device 1 to attach the second information to the second surface without changing the orientation of the infusion container 503.

[0221] In this embodiment, the third reading unit 122 reads the first information attached to the first surface SF1 from a position facing the rear end 362. Then, when the third reading unit 122 can read the first information, the printing / inspection unit 50 located below the infusion shelf 30 affixes the second label LA12 to the second surface SF2. Therefore, as shown by the reference characters 1051 to 1053 in Fig. 19, the second transport unit 120 can affix the second label LA12 to the second surface SF2 facing in a direction other than the predetermined direction without changing the orientation of the infusion container 503.

[0222] In addition, after the third reading unit 122 reads the first information, the applying unit affixes the second label LA12 to the surface of the infusion container 503. This allows the co-infusion device 1 to read the first information from the infusion container 503 before attaching the second information, which is different from the first information originally attached to the surface of the infusion container 503, to the surface of the infusion container 503. Therefore, the co-infusion device 1 can avoid the occurrence of a failure to read the first information due to the attachment of the second information.

[0223] (First label and second label) In Figure 20, symbol 1061 indicates an example of an infusion container 503 in which a first label LA11 is affixed to a first surface SF1 of the body 5031, and symbol 1062 indicates an example of an infusion container 503 in which a second label LA12 is affixed to a second surface SF2 of the body 5031.

[0224] The first label LA11 affixed to the first surface SF1 by the pharmaceutical manufacturer includes information about the infusion injected into the infusion container 503 by the pharmaceutical manufacturer. The information about the infusion includes information indicating the first information, the pharmaceutical manufacturer (manufacturer), the distributor (distributor), the composition of the infusion, the amount contained, the expiration date, and the serial number. The information about the infusion may be in the form of a barcode or text information.

[0225] In the example shown by reference numeral 1061 in Fig. 20, the name of the infusion, which is an example of the first information, "XX saline injection 100mL / B", the manufacturer of the drug, and the distributor are shown as text information on the first label LA11. Also, the first label LA11 shows a barcode BC11.

[0226] The second label LA12 affixed to the second surface SF2 by the printing / inspection unit 50 and the second conveying section 120 includes the above-mentioned information about the infusion container 503 into which the drug has been injected. Note that the various pieces of information included in the information about the infusion container 503 may be an example of second information different from the first information. In other words, among the information about the infusion container 503, information other than the information indicating the type of drug injected into the infusion container 503 (e.g., drug name) may also be an example of second information different from the first information.

[0227] In the example shown by reference numeral 1062 in Fig. 20, the ward name, mixed injection date, order number, patient ID, and patient name are shown as text information on the second label LA12. In addition, the Rp number, infusion name "XX saline injection 100mL / B", and drug name "XX intravenous injection 3g" are shown as text information on the second label LA12. Also, the second label LA12 shows a barcode BC12.

[0228] The barcode BC12 is printed so that, when the second label LA12 is affixed to the infusion container 503, the longitudinal direction of the barcode BC12 is approximately parallel to the longitudinal direction of the infusion container 503 (the direction approximately perpendicular to the bottom surface).

[0229] Although not shown, as described above, if the printing / inspection unit control unit 148 determines that the inspection result is unsuitable, the affixing unit 54 affixes an unsuitable information label to the second surface SF2. The unsuitable information label is affixed at a position that does not overlap with at least a portion of the first label LA11 (e.g., the infusion name and / or barcode BC11). The unsuitable information may be indicated by, for example, letters or symbols. For example, the unsuitable information may be an X mark.

[0230] The above-mentioned various effects can be achieved even if the second information is information printed on the second label LA12 other than the information indicating the type of the medicine, or is inappropriate information. The above-mentioned various effects can be achieved even if the second information is information indicating that the mixed injection process may not have been performed correctly.

[0231] (Modification) In this embodiment, the second label LA12 including the second information is affixed to the infusion container 503. Not limited to this, the second information may be affixed directly to the infusion container 503. For example, the printing unit 51 may eject ink onto the infusion container 503 located at the affixing position PO50, thereby affixing the second information directly to the infusion container 503. In this case, the second label LA12 on which the second information is printed is not required, and therefore the running costs can be reduced.

[0232] In this embodiment, the infusion shelf 30 and the printing and inspection unit 50 are positioned so that the printing and inspection unit 50 can affix the second label LA12 to the infusion container 503 without changing the orientation of the infusion container 503 taken out of the infusion shelf 30 by the second transport section 120. Therefore, if the infusion container 503 is stored on the infusion shelf 30 with the first surface SF1 facing the rear, the second label LA12 is affixed to the second surface SF2 through the operation shown in FIG.

[0233] However, it is not necessary that the infusion shelf 30 and the printing / inspection unit 50 are positioned as described above. It is sufficient that the application unit can affix the second label LA12 to the infusion container 503 based on the orientation of the first surface SF1 recognized by the recognition unit so as not to overlap at least the first information. In this case, the second transport unit 120 may change the orientation of the infusion container 503 that it is holding based on the recognition result of the recognition unit.

[0234] In the present embodiment, the above-mentioned applying unit is described as attaching the second label LA12 to the surface of the infusion container 503 at a position that does not overlap the first information. However, if it is only necessary for the applying unit to realize a configuration in which the third reading unit 122 reads the first information and then attaches the second label LA12 to the surface of the infusion container 503, the applying unit may attach the second information to a position that overlaps the first information. Even in this case, the third reading unit 122 reads the first information before attaching the second information, so that the co-infusion device 1 can avoid the occurrence of a reading failure of the first information. And, even in this case, since the control unit 140 can recognize the first information, it can determine whether the infusion container 503 used in the co-infusion process is the same type as the infusion container 503 indicated in the preparation / administration data.

[0235] In addition, when the second information is affixed so as to overlap the first information, for example, the attachment portion 54 and the guide portion 56 do not have to be positioned below the infusion shelf 30, but may be positioned on the opposite side of the infusion shelf 30, across the transport path of the infusion container 503 by the second transport portion 120.

[0236] [Specific configuration of infusion receiving shelf] Fig. 21 is a front view showing an example of the infusion receiving shelf 60. Fig. 22 is a side view showing an example of the infusion receiving shelf 60. Fig. 23 is a diagram showing an example of the shape of the rail portion 62. Fig. 24 is a diagram for explaining the shutter 63.

[0237] 21, the infusion receiving shelf 60 includes a pair of rail parts 62 capable of suspending and holding the infusion container 503 into which a drug has been injected by the mixing unit 40. The rail parts 62 suspend and hold a part of the neck part 5033 of the infusion container 503 (the head part of the infusion container 503). The rail parts 62 are an example of a suspending holder capable of suspending and holding the infusion container 503. The infusion receiving shelf 60 may be provided with one or more rail parts 62, and in this embodiment, four rail parts 62 are provided.

[0238] Since the infusion receiving shelf 60 is provided with the rail portion 62, the infusion container 503 after drug injection can be suspended and held. Therefore, even infusion containers 503 that are difficult to stand on their own can be held in an aligned state. The rail portion 62 can hold the infusion containers 503 in an aligned state, so that the user can easily take them out. Also, unlike a case where multiple infusion containers 503 after drug injection are placed on a tray (not shown), the rail portion 62 can hold the infusion containers 503 in an attractive manner and can reduce the risk of damage to the infusion containers 503 due to collision between the infusion containers 503.

[0239] As shown in Figure 22, the rail portion 62 extends in the front-to-rear direction (±Y-axis direction) of the co-infusion device 1, and includes a first portion 621 to which the infusion container 503 is handed over by the second conveying portion 120, and a second portion 622 from which the infusion container 503 held by the rail portion 62 is removed.

[0240] The second transport section 120 delivers the infusion container 503 into which a drug has been injected by the mixing unit 40 to the rail section 62 at the first portion 621. Specifically, the second transport section 120 delivers the infusion container 503 after drug injection, on whose second surface SF2 a second label LA12 has been affixed by the printing / inspection unit 50, to the rail section 62. The second transport section 120 delivers the infusion containers 503 after drug injection in sequence to the rail section 62, whereby the rail section 62 holds the multiple infusion containers 503 in a row.

[0241] The second transport section 120 delivers the infusion container 503 to the rail section 62 with the second surface SF2 of the infusion container 503, to which the second label LA12 is affixed, facing in the direction seen from the first part 621 to the second part 622 (the -Y axis direction).

[0242] Specifically, as shown by reference numerals 1052 to 1054 in Fig. 19, the second transport unit 120 adheres the second label LA12 to the second surface SF2 opposite to the first surface SF1 of the infusion container 503 while adsorbing the first surface SF1 to which the first label LA11 is attached. After that, the second transport unit 120 moves the infusion container 503 to a position facing the infusion receiving shelf 60 while adsorbing the first surface SF1 without changing the orientation of the infusion container 503. After that, as shown by reference numeral 1055 in Fig. 19 and Fig. 22, the second transport unit 120 moves to the infusion receiving shelf 60 side (the front direction of the co-infusion device 1; -Y axis direction). As a result, as shown by reference numeral 1056 in FIG. 19, the second transport section 120 delivers the infusion container 503 to the rail section 62 so that the second surface SF2 to which the second label LA12 is affixed faces the front of the co-infusion apparatus 1.

[0243] By transferring the infusion container 503 to the rail portion 62 in this manner, the infusion container 503 can be held on the infusion receiving shelf 60 with the second label LA12 facing forward, as shown in Figures 21 and 22. Then, when, for example, removing the infusion container 503 from the infusion receiving shelf 60, the user can easily recognize the information indicated on the second label LA12 (information regarding the infusion container 503 after drug injection).

[0244] 22, the rail portion 62 is provided on the infusion receiving shelf 60 at an incline such that the position of the second portion 622 is lower than the position of the first portion 621 when viewed from the left-right direction (±X-axis direction) of the co-infusion device 1. This allows the rail portion 62 to move the infusion container 503 held by the first portion 621 from the first portion 621 to the second portion 622 side by the weight of the infusion container 503. In other words, by providing the rail portion 62 at an incline as described above, the rail portion 62 functions as a moving portion that moves the held infusion container 503 from the first portion 621 to the second portion 622.

[0245] 21 and 23, the infusion receiving shelf 60 includes a rail holding portion 69 that holds each of the pair of rail portions 62. The pair of rail portions 62 extend inward of the rail holding portion 69 (in a direction in which the pair of rail portions 62 approach each other from the rail holding portion 69). In addition, as shown by the reference numeral 1071 in FIG. 23, the rail portion 62 includes a support portion 626 that supports the neck portion 5033 of the infusion container 503.

[0246] In this embodiment, the shape of the cross section of the rail portion 62 perpendicular to the extending direction of the rail portion 62 satisfies the following two conditions. The support portions 626 of the pair of rail portions 62 are closer to each other than the dimensions of the neck portion 5033 of the infusion container 503. The pair of rail portions 62 are inclined downward as they move away from the support portion 626 in each of the pair of rail portions 62 . In other words, the cross-sectional shape of the pair of rail portions 62 is a shape that widens from the support portion 626 at the center.

[0247] When the rail portion 62 has the above-mentioned shape, the contact between the rail portion 62 and the neck portion 5033 is not surface contact, but point contact when the infusion container 503 is held as indicated by reference numeral 1072 in Fig. 23. Also, when the infusion container 503 is held as indicated by reference numeral 1073 in Fig. 23, the contact between the rail portion 62 and the neck portion 5033 is line contact. Therefore, the infusion container 503 suspended from the rail portion 62 slides smoothly.

[0248] However, the cross-sectional shape of the pair of rail portions 62 is not limited to the above-mentioned flared shape, and may be any shape that allows the pair of rail portions 62 to come into point or line contact with the infusion container 503.

[0249] For example, as shown by reference numeral 1074 in FIG. 23, the infusion receiving shelf 60 may have a pair of rail parts 62A instead of the pair of rail parts 62. The pair of rail parts 62A is held by a rail holding part 69, similar to the pair of rail parts 62. The pair of rail parts 62A is not a plate-shaped member like the pair of rail parts 62, but is a member having a support part 626 that supports the infusion container 503 in a protruding shape. By making the support part 626 protruding, similar to the rail part 62, only a part of the rail part 62A, not the entire rail part 62A, can be brought into contact with the infusion container 503, and the contact area with the infusion container 503 can be reduced. Therefore, even with the rail part 62A, point contact or line contact with the infusion container 503 described above can be realized, and the sliding of the infusion container 503 can be improved.

[0250] In addition, the pair of rail parts do not have to be plate-like members or members having a protruding shape, and may be linear members that support the infusion container 503 by point contact or line contact. In other words, in the pair of rail parts, the shape of the part where the pair of rail parts contact the infusion container 503 when the infusion container 503 is suspended from the pair of rail parts may be linear.

[0251] 21 and 22, the second portion 622 of the rail portion 62 is provided with a shutter 63 (stopper) for preventing the movement of the infusion container 503 held by the rail portion 62. The shutter 63 is biased in a closing direction of the shutter 63. The shutter 63 is biased by, for example, a spring (not shown). As a result, the shutter 63 is in a closed state in a normal state, which reduces the possibility that the infusion container 503 held by the rail portion 62 will fall off the second portion 622. The user can open the shutter 63 according to the number of infusion containers 503 to be removed.

[0252] Reference numeral 1081 in Fig. 24 illustrates a closed state of the shutter 63, and reference numeral 1082 illustrates an open state of the shutter 63. In reference numerals 1081 and 1082 in Fig. 24 and reference numeral 1083 described later, the arrows pointing in the -Y-axis direction indicate the removal direction of the infusion container 503 held by the rail portion 62.

[0253] As shown by reference numerals 1081 and 1082 in FIG. 24, in this embodiment, the shutter 63 is provided at one end of the pair of rail portions 62 so as to be rotatable around a rotation axis A63 having an axis in the vertical direction. The shutter 63 opens and closes the second portion 622 by rotating around the rotation axis A63. Specifically, a support portion 64 that supports the shutter 63 is connected to the rotation axis A63. In addition, an abutment portion 65 that the support portion 64 abuts against extends from the end of the rail portion 62. As shown by reference numeral 1082 in FIG. 24, the support portion 64 rotates between the reference line L11 and the abutment portion 65. The abutment portion 65 may be provided at a position where the infusion container 503 can be removed when the shutter 63 is fully opened.

[0254] As shown by reference numeral 1081 in FIG. 24, in the closed state, the shutter 63 abuts against the infusion container 503 held by the rail portion 62, thereby preventing the movement of the infusion container 503 in the removal direction. From this state, the user holds the leading infusion container 503 and pulls the infusion container 503 in the removal direction with a force equal to or greater than the biasing force of a spring (not shown). This pulling causes the infusion container 503 to open the shutter 63 while abutting against it, so that the user can remove the infusion container 503. When the infusion container 503 is removed, the shutter 63 is closed by the biasing force of the spring. This prevents the movement of the subsequent infusion containers 503 in the removal direction. Therefore, the user can remove the leading infusion container 503 without performing any operation other than pulling the infusion container 503.

[0255] When a user wishes to remove multiple infusion containers 503 (e.g., all of the multiple infusion containers 503 held by the rail portion 62) at once, the user grips the support portion 64 and rotates it toward the abutment portion 65 to maintain the shutter 63 in an open state. When the user has removed the desired number of infusion containers 503, the user releases the support portion 64, and the shutter 63 is closed by the biasing force of the spring. Therefore, the user can remove the desired number of infusion containers 503 simply by operating the support portion 64. Note that the user may also operate the support portion 64 when removing one infusion container 503.

[0256] In this way, by biasing the shutter 63 in the closing direction, the possibility of the infusion container 503 falling off the rail portion 62 is reduced, and the user can remove the desired number of infusion containers 503, whether one or multiple, with a simple operation.

[0257] 24, an abutment surface 631 of the shutter 63 with the infusion container 503 held by the rail portion 62 is inclined with respect to the removal direction (movement direction) of the infusion container 503 when the shutter 63 is in the closed state. Specifically, when viewed from above, the abutment surface 631 is inclined with respect to the removal direction when the shutter 63 is in the closed state such that the distance between the shutter 63 and the rail portion 62 on which the shutter 63 is not provided becomes shorter toward the removal direction.

[0258] Since the contact surface 631 is inclined with respect to the removal direction, the operation angle for opening the shutter 63 can be made smaller than when the contact surface 631 is not inclined (when the contact surface 631 is perpendicular to the extension direction of the rail portion 62 when the shutter 63 is closed). This improves the operability of opening and closing the shutter 63. In addition, since the operation angle can be made smaller, the shutter 63 can be closed immediately after the infusion container 503 is removed. This reduces the possibility that the infusion container 503 behind the removed infusion container 503 will be dispensed together with the removed infusion container 503.

[0259] Reference numeral 1083 in Fig. 24 is a diagram showing an example of the positional relationship in the up-down direction between the rail portion 62 and the shutter 63, and reference numeral 1084 is a diagram showing an example of the positional relationship as a comparative example. Reference numeral 1083 in Fig. 24 is a diagram when the shutter 63 is in an open state.

[0260] As shown by reference numeral 1083 in Fig. 24, in this embodiment, the shutter 63 is located below a plane including the bottommost part of the rail portion 62. This means that the distance (height) H60 between the plane and the upper surface of the shutter 63 is greater than 0. Therefore, as shown by reference numerals 1081 to 1083 in Fig. 24, the rail portion 62 and the shutter 63 can be overlapped so that they do not come into contact (interfere with each other). Reference numeral OL of reference numerals 1081 to 1083 in Fig. 24 indicates the overlap position between the rail portion 62 and the shutter 63.

[0261] As shown by reference numerals 1082 and 1083 in Fig. 24, even when the shutter 63 is in an open state, the shutter 63 is located below the rail portion 62, so that even when the shutter 63 is open, as shown by reference numeral 1084 in Fig. 24, no gap D60 is formed between the rail portion 62 and the shutter 63. As shown by reference numeral 1084 in Fig. 24, if the gap D60 exists, the neck portion 5033 of the infusion container 503 moving on the rail portion 62 in the removal direction will get caught on the shutter 63. By defining the positional relationship between the shutter 63 and the rail portion 62 so that a part of the shutter 63 overlaps with the rail portion 62 even in the open state, the possibility that the infusion container 503 will get caught on the shutter 63 can be reduced.

[0262] In this embodiment, the printing / inspection unit 50 and the infusion receiving shelf 60 are positioned so that the second transport unit 120 can store the infusion container 503 with the second label LA12 attached thereto on the infusion receiving shelf 60 with the second surface SF2 facing the removal direction without changing the orientation of the infusion container 503. However, such positioning is not necessarily required. In this case, for example, the second transport unit 120 may change the orientation of the infusion container 503 it holds so that the infusion container 503 is stored on the infusion receiving shelf 60 with the second surface SF2 facing the removal direction.

[0263] In this embodiment, the pair of rail parts 62 are fixed to the infusion receiving shelf 60, but may be detachable from the infusion receiving shelf 60. In this case, the user can remove the pair of rail parts 62 from the infusion receiving shelf 60 while the infusion container 503 is being held, and take them out of the housing of the co-infusion device 1. Therefore, the infusion container 503 can be removed from the rail parts 62 outside the housing of the co-infusion device 1.

[0264] (Modification) The hanging holding portion provided on the infusion receiving shelf 60 does not have to be a rail portion 62 (rail-shaped), and may be hung at a position other than the neck portion 5033, for example, by hanging through a hole provided in the body portion 5031.

[0265] Furthermore, the moving part provided on the infusion receiving shelf 60 does not necessarily have to be the rail part 62 inclined so that the position of the second part 622 is lower than the position of the first part 621. The moving part may be a mechanism separate from the hanging holding part, which moves the infusion container 503 suspended from the hanging holding part from the first part 621 to the second part 622. The mechanism may be, for example, a mechanism for pushing and moving the infusion container 503, or a mechanism for holding and moving the infusion container 503. When the mechanism is applied to the rail part 62, the rail part 62 does not necessarily have to be inclined.

[0266] Moreover, the co-infusion apparatus 1 may be provided with an infusion receiving shelf 60A as shown in FIG. 25, instead of the infusion receiving shelf 60. FIG. 25 is a diagram showing an example of the infusion receiving shelf 60A. As shown by reference numeral 1091 in FIG. 25, the infusion receiving shelf 60A includes a first storage section 67 and a second storage section 68, instead of the rail section 62. In this modification, the infusion receiving shelf 60A can be pulled out forward (in the -Y-axis direction) of the co-infusion apparatus 1.

[0267] The first storage section 67 is a space section that stores the hanging holding section 66. With the hanging holding section 66 stored in the first storage section 67, the second transport section 120 transfers the infusion container 503 after drug injection from the second storage section 68 side to the hanging holding section 66. The second storage section 68 is a space section that stores the infusion container 503 for which the third reading section 122 was unable to read the first information on the first label LA11, and the infusion container 503 for which the printing / inspection unit control section 148 has determined that the inspection result is unsuitable. Therefore, in this modification, the second transport section 120 transfers the infusion container 503 for which the inspection result is determined to be suitable to the hanging holding section 66. In addition, the second transporting section 120 transports to the second storage section 68 the infusion container 503 from which the third reading section 122 was unable to read the first information, and the infusion container 503 from which the inspection result has been determined to be unsuitable.

[0268] The hanging holder 66 is detachable from the infusion receiving shelf 60A. In this modification, the user can store the hanging holder 66 from above where the first storage section 67 is open, and remove the hanging holder 66 upward.

[0269] Notches are provided at both ends of hanging holding part 66. Positioning pins are provided at positions facing the notches on first top surface part 671 and second top surface part 672 of the box body constituting first housing part 67. Therefore, hanging holding part 66 is housed in first housing part 67 at the positions of the positioning pins.

[0270] When the first storage section 67 is viewed from the left and right direction, the position of the first upper surface section 671 on the side where the infusion container 503 is handed over is higher than the position of the second upper surface section 672. Therefore, in the first storage section 67, the first upper surface section 671 side of the hanging holding section 66 is higher than the second upper surface section 672 side. Therefore, the infusion container 503 suspended from the hanging holding section 66 moves toward the second upper surface section 672 side due to its own weight.

[0271] As shown by reference numeral 1092 in FIG. 25, the hanging holding part 66 has a pair of rail parts 661 capable of holding the neck part of the infusion container 503 by hanging it. In the first part of the hanging holding part 66, where the infusion container 503 is transferred, a step part 662 is provided on the top surface side of the hanging holding part 66 from the rail parts 661. In the second part of the hanging holding part 66, which is the side opposite to the side where the infusion container 503 is transferred, a wall part is provided connecting the rail parts 661 and the top surface of the hanging holding part 66. Therefore, the hanging holding part 66 can receive the infusion container 503 from the first part, and can reduce the possibility that the infusion container 503 held by the hanging holding part 66 will fall off from the first part or the second part when the user carries the hanging holding part 66.

[0272] 25, by placing the hanging holding part 66 holding the infusion container 503 on a table, the state in which the hanging holding part 66 holds the infusion container 503 is released. Therefore, when the user pulls the hanging holding part 66 in the direction of the arrow while holding the infusion container 503, the step 662 does not interfere with the neck of the infusion container 503. Therefore, the user can remove the infusion container 503 from the hanging holding part 66.

[0273] Summary of the First Embodiment (B1) The co-infusion device comprises a plurality of equipment holding units capable of holding drug containers for containing drugs, and an equipment transporting unit that transports at least one of the plurality of equipment holding units to a work area where a user removes the drug container held in the equipment holding units, and in response to an instruction to collect the drug container, the equipment transporting unit transports the equipment holding unit holding the drug container designated for collection to the work area.

[0274] (B2) The co-injection device, in the above (B1), is provided with a reading unit that reads type information indicated on a drug container held in the equipment holding unit, and the equipment transporting unit transports the equipment holding unit, which holds a drug container designated as a drug container to be collected, for which the type information could not be read, to the working area.

[0275] (B3) In the co-injection device, in the above (B1) or (B2), the equipment transporting unit transports an equipment holding unit that holds the drug container designated by the user as the drug container designated as the drug container to be collected, to the working area.

[0276] (B4) In the co-injection device, in any of (B1) to (B3) above, when at least two of the plurality of equipment holding parts each hold a drug container designated as the recovery target, the equipment transporting part preferentially transports to the working area the equipment holding part which holds the drug container which is to be held in the equipment holding part earlier.

[0278] (B6) The co-infusion device, in (B5) above, may be provided with a removal unit which removes the drug container from the equipment storage shelf, and when it is the equipment storage shelf from which the removal unit has removed the drug container is to be set to the recovery mode, the equipment storage shelf may not be set to the recovery mode, and the next equipment storage shelf in the sequence may be set to the recovery mode.

[0279] (B7) The co-infusion device comprises a plurality of equipment holding units capable of holding a drug container for containing a drug, an injection unit for injecting the drug into an infusion container for containing an infusion, a container transport unit for transporting the drug container from the equipment holding unit to the injection unit, and an equipment transport unit for transporting at least one of the plurality of equipment holding units to a removal position where the container transport unit removes the drug container from the equipment holding unit, and after the container transport unit removes the drug container from the equipment holding unit, the equipment transport unit transports an equipment holding unit holding a drug container containing the same type of drug as the removed drug container to the removal position without receiving a next injection instruction.

[0280] (C1) The co-infusion device includes a hanging holding section capable of hanging and holding an infusion container containing an infusion, and a pushing section that pushes the infusion container by contacting a body of the infusion container hung from the hanging holding section.

[0282] (C3) In the co-infusion device of (C2) above, when the reading unit is unable to read the infusion type information even after moving the reading position in the width direction of the infusion container, the orientation change unit changes the orientation of the reading unit along the height direction of the infusion container from which the infusion type information is read.

[0283] (C4) In the co-infusion device, the orientation change unit changes the orientation of the reading unit in the above (C2) or (C3) so that the reading position faces the infusion type information attached to the surface of the infusion container.

[0286] (E1) The co-infusion device includes an injection section that injects a drug into an infusion container that holds an infusion liquid, a hanging holding section that can suspend and hold the infusion container into which the drug has been injected by the injection section, and a transfer section that transfers the infusion container into which the drug has been injected by the injection section to the hanging holding section.

[0287] (E2) In the co-infusion device of (E1) above, second information different from first information indicating the type of infusion is provided on a side of the infusion container different from the side on which the first information indicating the type of infusion is provided, and the hanging holding part has a first part to which the infusion container is delivered by the delivery part and a second part from which the infusion container held in the hanging holding part is removed, and the delivery part delivers the infusion container to the hanging holding part with the side of the infusion container on which the second information is provided facing in the direction seen from the first part to the second part.

[0288] (E3) In the co-infusion device of (E1) or (E2) above, the hanging holding part comprises a first part to which the infusion container is handed over by the delivery part and a second part from which the infusion container held in the hanging holding part is removed, a moving part that moves the infusion container held in the hanging holding part from the first part to the second part, and a shutter provided in the second part to prevent movement of the infusion container, and the shutter is biased in the direction of closing the shutter.

[0293] [Embodiment 2] Other embodiments of the present disclosure will be described below. For convenience of explanation, the same reference numerals are given to members having the same functions as those described in the above embodiment, and the explanations will not be repeated. The same applies to other embodiments. In this embodiment, the operation of the application unit applying second information to the infusion container 503 will be mainly described by exemplifying the operation of the second transport unit 120 pressing the second label LA12 against the infusion container 503 and the application unit 54 applying the second label LA12 to the infusion container 503.

[0294] [Device configuration example] 4, the control unit 140 may include a determination unit 150. The determination unit 150 determines whether the second information is provided on the second surface SF2 of the infusion container 503. Therefore, the control unit 140 can execute various processes after the second information is not provided, such as notifying the user when the second information is not provided.

[0295] For example, the determination unit 150 may determine that the second information is provided on the second surface SF2 when the second reading unit 53 reads the second information after the second information providing operation. The second information providing operation may be, for example, the attachment operation of the second label LA12 by the second conveying unit 120 and the attachment unit 54.

[0296] After the second transport unit 120 moves the infusion container 503 it is holding to the attachment position PO50 (see FIG. 18) and the attachment unit 54 attaches the second label LA12 to the second surface SF2, the control unit 140 performs a reading operation of the second reading unit 53. The second reading unit 53 only needs to read the pattern (e.g., barcode or characters) attached to the second label LA12. The second reading unit 53 may be a barcode reader when reading a barcode, or may be a camera when reading characters, etc.

[0297] When the second information is directly provided on the second surface SF2, the determination unit 150 may determine whether the second information is provided on the second surface SF2 by analyzing an image of the second surface SF2 captured by a camera. The camera is an example of a reading unit that reads the second information.

[0298] Also, for example, when the determination unit 150 determines that the second label LA12 on which the second information is printed is affixed to the second surface SF2 after the second information affixing operation, the determination unit 150 may determine that the second information is affixed to the second surface SF2. The determination unit 150 may determine that the second label LA12 is affixed to the second surface SF2 when the internal pressure of the suction mechanism 541 included in the affixing unit 54 drops below the internal pressure in the suction state of the second label LA12.

[0299] The moving mechanism 542 moves the suction mechanism 541 so that the second label LA12 is located at the attachment position PO50 after the suction mechanism 541 has adsorbed the second label LA12 dispensed by the printing unit 51. The second conveying unit 120 then moves the infusion container 503 it is holding to the attachment position PO50, thereby attaching the second label LA12 to the second surface SF2. In this embodiment, in this state, the moving mechanism 542 moves the suction mechanism 541 to the suction position of the second label LA12, so that the suction pad of the suction mechanism 541 moves away from the second label LA12 attached to the second surface SF2.

[0300] Therefore, when the second label LA12 is affixed to the second surface SF2, the internal pressure of the suction mechanism 541 decreases. On the other hand, when the second label LA12 is not affixed to the second surface SF2 (when affixing fails), the suction mechanism 541 keeps suctioning the second label LA12, so the internal pressure of the suction mechanism 541 does not change. The determination unit 150 can determine whether the second label LA12 is affixed to the second surface SF2 based on the presence or absence of this change.

[0301] The printing and inspection unit 50 may be equipped with a pressure gauge (not shown) that detects the internal pressure of the tube that constitutes the suction mechanism 541. Furthermore, a threshold value that enables the control unit 140 to detect that the suction pad has been separated from the second label LA12 affixed to the second surface SF2 may be set in the memory unit 200, for example, through an experiment or the like. The determination unit 150 may determine whether the second label LA12 has been affixed to the second surface SF2 by comparing the internal pressure detected by the pressure gauge with the threshold value.

[0302] The determination unit 150 may determine whether the second label LA12 is attached to the second surface SF2 by analyzing the image of the second surface SF2 captured by the camera. The camera is an example of a reading unit that reads the second label LA12.

[0303] In addition, the determination unit 150 may determine that the second label LA12 is not attached to the second surface SF2 when a member related to attaching the label breaks down or when the label is missing. In this case, even if the co-infusion device 1 does not have a mechanism for detecting whether the second label LA12 is attached to the infusion container 503, the determination unit 150 can determine that the second label LA12 is not attached to the infusion container 503 by detecting the failure of the member or the missing label.

[0304] As shown in FIG. 4, the printing / inspection unit 50 may include a fault detection unit 58. The fault detection unit 58 is a detection unit that detects faults in components involved in affixing the label. Examples of components involved in affixing the label include the printing unit 51 and a vacuum pump. In this case, the fault detection unit 58 is provided in each of the printing unit 51 and the vacuum pump. When the fault detection unit 58 detects a fault in the target component, the judgment unit 150 judges that the second label LA12 is not affixed to the second surface SF2.

[0305] The above determination may be made, for example, when a failure of the target member is detected during the sticking operation of the second label LA12. Specifically, the above determination may be made, for example, when a failure of the target member is detected during the sticking operation of the second label LA12, or when a failure of the target member is detected before the sticking operation of the second label LA12 and the sticking operation is performed without resolving the condition.

[0306] 4, the printing / inspection unit 50 may include a label supply unit 55 (also shown in FIG. 17) and a missing label detection unit 59. The label supply unit 55 supplies the label on which the second information is printed by the printing unit 51 to the printing unit 51. The missing label detection unit 59 is a detection unit that detects missing labels stored in the label supply unit 55. When the missing label detection unit 59 detects a missing label, the judgment unit 150 judges that the second label LA12 is not affixed to the second surface SF2.

[0307] The above determination may be made, for example, when a label is detected to be missing during the attaching operation of the second label LA12. Specifically, the above determination may be made, for example, when a label is detected to be missing during the attaching operation of the second label LA12, or when a label is detected to be missing before the attaching operation of the second label LA12 and the attaching operation is performed without resolving the condition.

[0308] When the determining unit 150 determines that the second label LA12 is not attached to the second surface SF2, the second transporting unit 120 may dispense the infusion container 503 without the second label LA12 (also referred to as an unlabeled infusion container 503) to the infusion receiving shelf 60. This allows the user to remove the infusion container 503 without the second label LA12 from the infusion receiving shelf 60, in the same way as the infusion container 503 with the second label LA12 attached. The second transporting unit 120 is an example of a dispensing unit that dispenses the infusion container 503 to the infusion receiving shelf 60.

[0309] For example, the touch panel control unit 149 may display, on the touch panel 80, the second information included in the second label LA12 that was to be affixed to the infusion container 503. In this case, the user can know the type of injected drug, the patient's name, the ward, and the like, for the unlabeled infusion container 503. Therefore, by making it possible to remove the unlabeled infusion container 503 from the co-infusion device 1, the user can use the infusion container 503.

[0310] Also, for example, a light emitting member (not shown) (e.g., LED; Light Emitting Diode) may be provided corresponding to the rail portion 62 of the infusion receiving shelf 60. After the second transport unit 120 dispenses the unlabeled infusion container 503, the control unit 140 may light up the light emitting member corresponding to the rail portion 62 holding the unlabeled infusion container 503. This allows the control unit 140 to notify the user of the rail portion 62 holding the unlabeled infusion container 503. The control unit 140 may light up the light emitting member corresponding to the rail portion 62 based on, for example, the detection result of the first infusion detection unit 101.

[0311] The second transport section 120 may dispense the unlabeled infusion containers 503 to the infusion receiving shelf 60 when the number of unlabeled infusion containers 503 stored on the infusion receiving shelf 60 is less than a predetermined number.

[0312] The greater the number of unlabeled infusion containers 503 stored on the infusion receiving shelf 60, the more difficult it becomes for the user to identify the unlabeled infusion container 503 that the user desires to remove, and the more time and effort it takes to remove the desired unlabeled infusion container. By restricting the storage of more than a predetermined number of unlabeled infusion containers 503 on the infusion receiving shelf 60, the user can easily recognize the presence of unlabeled infusion containers 503, thereby reducing the time and effort required to remove the unlabeled infusion containers 503. In addition, the possibility that the processing of the control unit 140 becomes complicated and the possibility that the device configuration becomes complicated can be reduced.

[0313] The predetermined number may be determined in consideration of the effort of the user, the complexity of the processing of the control unit 140, the complexity of the device configuration, etc. The predetermined number may be set to 1, for example. Information indicating the predetermined number is stored in the storage unit 200.

[0314] 4, the infusion receiving shelf 60 may include a first infusion detection unit 101 that detects the infusion container 503 located in a first portion 621 (see FIG. 22) and a second infusion detection unit 102 that detects the infusion container 503 located in a second portion 622 (see FIG. 22). The control unit 140 may count the infusion containers 503 stored in the infusion receiving shelf 60 based on the detection results of the first infusion detection unit 101 and the second infusion detection unit 102.

[0315] For example, when the first infusion detection unit 101 detects an infusion container 503 dispensed to the infusion receiving shelf 60, the control unit 140 increases the number of infusion containers 503 stored in the infusion receiving shelf 60 by 1. On the other hand, when the second infusion detection unit 102 detects an infusion container 503 removed from the infusion receiving shelf 60, the control unit 140 decreases the number of infusion containers 503 stored in the infusion receiving shelf 60 by 1. This allows the control unit 140 to count the infusion containers 503 stored in the infusion receiving shelf 60.

[0316] Before the unlabeled infusion container 503 is accommodated on the infusion receiving shelf 60, the determination unit 150 determines that the second label LA12 is not affixed to the infusion container 503. Therefore, when the unlabeled infusion container 503 is dispensed to the infusion receiving shelf 60, the control unit 140 increments the number of infusion containers 503 accommodated on the infusion receiving shelf 60 by 1 and can specify that the unlabeled infusion container 503 has been dispensed to the infusion receiving shelf 60.

[0317] Consider the case where the predetermined number is set to 1. In this case, when unlabeled infusion containers 503 are stored on the infusion receiving shelf 60, the control unit 140 may determine that the unlabeled infusion containers 503 have been removed from the infusion receiving shelf 60 when all of the stored infusion containers 503 have been removed from the infusion receiving shelf 60. This allows the control unit 140 to determine that the number of unlabeled infusion containers 503 stored on the infusion receiving shelf 60 has fallen below the predetermined number (less than 1).

[0318] 21, when a plurality of rail parts 62 are provided on the infusion receiving shelf 60, the predetermined number may be set for each rail part 62. Also, the first infusion detection unit 101 and the second infusion detection unit 102 may be provided for each rail part 62. In this case, the control unit 140 can count the number of infusion containers 503 accommodated for each rail part 62 and determine whether an infusion container 503 without a label can be dispensed.

[0319] [Example of processing related to affixing the second label] FIG. 26 is a flow chart showing an example of the determination as to whether or not the second label LA12 is attached, and the flow of the process of the control unit 140 associated with the determination.

[0320] 26, after the co-infusion device 1 is powered on, the control unit 140 determines whether a member related to label attachment has failed (S21) based on, for example, the detection result of the failure detection unit 58. The control unit 140 also determines whether a label stored in the label supply unit 55 has run out based on, for example, the detection result of the shortage detection unit 59 (S21).

[0321] If neither a failure of the above components nor a missing label is detected (YES in S21), the control unit 140 controls the operation of each component of the co-infusion device 1 to perform a co-infusion operation for a certain drug. The control unit 140 controls the second transport unit 120 and the attachment unit 54 to perform an attachment operation of the second label LA12 to the infusion container 503 after the drug injection (S22).

[0322] The determination unit 150 determines whether the second information is provided to the infusion container 503 after the sticking operation of the second label LA12. In this embodiment, the determination unit 150 determines whether the second reading unit 53 reads the second information after the sticking operation of the second label LA12 (S23). In addition, the determination unit 150 determines whether the internal pressure of the suction mechanism 541 has decreased below the internal pressure (threshold) in the suction state of the second label LA12 after the sticking operation of the second label LA12 (S24). The process of S23 and the process of S24 may be performed in parallel, or the process of S23 may be performed after the process of S24.

[0323] When the determination unit 150 determines that the second reading unit 53 has read the second information (YES in S23), it determines that the second label LA12 is affixed to the infusion container 503. When the determination unit 150 determines that the internal pressure of the suction mechanism 541 has decreased below the threshold value (YES in S24), it determines that the second label LA12 is affixed to the infusion container 503. As a result, the determination unit 150 determines that the second information is provided to the infusion container 503 (S25).

[0324] Then, the second transport control unit 145 controls the second transport unit 120 to dispense the infusion container 503 with the second label LA12 affixed thereto (also referred to as the infusion container 503 with a label) to the infusion receiving shelf 60 (S26). When the second label LA12 is affixed to the infusion container 503, the second transport control unit 145 dispenses the infusion container 503 with a label to the infusion receiving shelf 60, regardless of the number of infusion containers 503 without a label stored in the infusion receiving shelf 60.

[0325] On the other hand, when the control unit 140 determines in S21 that a failure of the above-mentioned component or a missing label is detected (NO in S21), the judgment unit 150 judges that the second information is not provided (S27). Specifically, the judgment unit 150 judges that the second label LA12 is not attached to the infusion container 503. The judgment unit 150 may make the above judgment when the attachment operation of the second label LA12 is performed in a state in which a failure of the above-mentioned component or a missing label continues to be detected. When NO in S21, the touch panel control unit 149 may display an image on the touch panel 80 indicating that the above-mentioned component is broken or that the label is missing.

[0326] Also, in S23, when the control unit 140 determines that the second information has not been read after the sticking operation of the second label LA12 (NO in S23), the determination unit 150 determines that the second label LA12 is not attached to the infusion container 503. Also, in S24, when the control unit 140 determines that the internal pressure of the suction mechanism 541 has not decreased below the threshold value after the sticking operation of the second label LA12 (NO in S24), the determination unit 150 determines that the second label LA12 is not attached to the infusion container 503. As a result, the determination unit 150 determines that the second information is not provided to the infusion container 503 (S27).

[0327] After the determination in S27, the touch panel controller 149 displays on the touch panel 80 an image indicating that the second information is not provided on the infusion container 503 (for example, an image indicating that the second label LA12 is not attached) (S28). At this time, the touch panel controller 149 may display on the touch panel 80 the second information included in the second label LA12 that was to be attached to the infusion container 503.

[0328] The control unit 140 determines whether the number of unlabeled infusion containers 503 stored on the infusion receiving shelf 60 is less than a predetermined number (S29). When the control unit 140 determines that the number of unlabeled infusion containers 503 is less than the predetermined number (YES in S29), it controls the second transport unit 120 to dispense the unlabeled infusion containers 503 to the infusion receiving shelf 60 (S26).

[0329] On the other hand, when the control unit 140 determines that the number of unlabeled infusion containers 503 is equal to or greater than the predetermined number (NO in S29), the touch panel control unit 149 displays an image on the touch panel 80 prompting the user to remove the unlabeled infusion containers 503 (S30). After that, the control unit 140 performs the process of S29 again.

[0330] Therefore, the control unit 140 waits to dispense the infusion container 503 to the infusion receiving shelf 60 until the unlabeled infusion container 503 is removed from the infusion receiving shelf 60 and the number of unlabeled infusion containers 503 stored on the infusion receiving shelf 60 falls below a predetermined number. Therefore, the control unit 140 can maintain the number of unlabeled infusion containers 503 stored on the infusion receiving shelf 60 below a predetermined number.

[0331] In S26, after the infusion containers 503 are dispensed to the infusion receiving shelf 60, the control unit 140 determines whether the number of unlabeled infusion containers 503 stored on the infusion receiving shelf 60 is less than a predetermined number (S31). When the control unit 140 determines that the number of unlabeled infusion containers 503 is less than the predetermined number (YES in S31), this flow ends.

[0332] On the other hand, when the control unit 140 determines that the number of unlabeled infusion containers 503 is equal to or greater than the predetermined number (NO in S31), the touch panel control unit 149 displays an image on the touch panel 80 to prompt the user to remove the unlabeled infusion containers 503 (S32). This allows the user to remove the unlabeled infusion containers 503, so that the number of unlabeled infusion containers 503 stored in the infusion receiving shelf 60 becomes less than the predetermined number. In this case, even if an unlabeled infusion container 503 occurs in the next mixed injection operation, the infusion container 503 can be stored in the infusion receiving shelf 60.

[0333] (Example of the start timing of the next mixed injection action) If the second reading unit 53 cannot read the second information (NO in S23) or if the internal pressure of the suction mechanism 541 does not drop below the threshold (NO in S24), there is a high possibility that the second label LA12 can be attached to the infusion container 503 into which the medicine is injected in the next mixed injection operation. This is because the above-mentioned components are not broken and the label is not missing, so there is a high possibility that the second label LA12 could not be attached only in this attachment operation for some reason. Therefore, if NO in S23 or NO in S24, the control unit 140 may perform the next mixed injection-related operation (for example, an injection operation of a medicine) at any timing thereafter. In this case, the control unit 140 may, for example, control the attachment unit 54 to discard the second label LA12 that could not be attached in a trash can (not shown). The control unit 140 may discard the second label LA12 that could not be attached in a trash can, for example, until the suction mechanism 541 adsorbs the second label LA12 related to the next co-infusion operation.

[0334] On the other hand, if a failure of the above-mentioned component or a missing label is detected (NO in S21), the second label LA12 cannot be affixed to the infusion container 503 into which the medicine is injected in the next mixed injection operation unless the above-mentioned component is repaired or replaced, or the label supply unit 55 is replenished with labels. When a notification is given in S30 and S32 to remove the infusion container 503 without a label, the user accesses the mixed injection device 1 to remove the infusion container 503 without a label from the infusion receiving shelf 60. Therefore, at this timing, the user is likely to repair or replace the above-mentioned component, or replenish the label supply unit 55 with labels.

[0335] Therefore, if the result of S21 is NO, the control unit 140 may perform the next mixed injection operation (e.g., drug injection operation) after the process of S29 or S31. As a result, when a predetermined number or more of unlabeled infusion containers 503 are stored in the infusion receiving shelf 60 and an unlabeled infusion container 503 is removed, the control unit 140 can perform the above operation assuming that the above-mentioned member has been repaired or the like. Therefore, it is possible to reduce the possibility that the infusion container 503 into which a drug has been injected by the next mixed injection will be left waiting to be dispensed to the infusion receiving shelf 60 due to a failure of the above-mentioned member or a missing label.

[0336] However, when waiting for dispensing to the infusion receiving shelf 60 as described above is permitted, the control unit 140 may perform the next mixed injection operation at any timing after the determination process of S21, as in the case of NO in S23 and NO in S24. In this case, the control unit 140 may refrain from resuming the mixed injection operation until a user operation indicating an instruction to resume the mixed injection operation is received.

[0337] (Modification) The control unit 140 may perform only one of the determination as to whether the second information has been read (processing of S23) and the determination as to whether the internal pressure of the suction mechanism 541 has decreased below the threshold value (processing of S24).

[0338] In addition, the control unit 140 may only perform one or two of the processes of determining whether a failure of the above-mentioned component or a missing label has been detected (S21), processing of S23, and processing of S24.

[0339] Furthermore, when the control unit 140 determines that a failure of the above-mentioned component or a missing label is detected before performing the operation of attaching the second label LA12 after starting the operation related to the mixed injection of a certain medicine, the operation of attaching the second label LA12 (the process of S22) may not be performed. In this case, the control unit 140 may not perform the processes of S23 and S24.

[0340] Also, if a failure of the above-mentioned member or a missing label is detected during the sticking operation of the second label LA12, the determination unit 150 may determine NO in S21.

[0341] Summary of Embodiments 1 and 2 (A1) The co-infusion device includes an injection unit that injects a medicine into an infusion container that holds an infusion and has first information indicating the type of infusion attached to its surface, an application unit that applies second information different from the first information to the surface of the infusion container, and a reading unit that reads the first information from the infusion container, and the application unit applies the second information to the surface of the infusion container after the reading unit reads the first information.

[0342] (A2) The co-infusion device includes an injection unit that injects a medicine into an infusion container that holds an infusion and has first information indicating the type of infusion attached to its surface, and an application unit that applies second information, different from the first information, to the surface of the infusion container, and the application unit applies the second information to the surface of the infusion container at a position that does not overlap with the first information.

[0343] (A3) In the co-infusion device according to (A1) or (A2) above, the second information is information indicating the type of the medicine.

[0344] (A4) In any one of the above (A1) to (A3), the co-infusion device is configured such that the application section applies the second information to a second surface of the infusion container, the second surface being different from the first surface to which the first information is applied.
