[0001] The present invention relates to a co-infusion device.

[0002] Patent Document 1 discloses an example of a co-infusion device. The co-infusion device of Patent Document 1 includes a drug filling unit and a co-infusion processing unit. A user places drug containers, components that may constitute a syringe, and an infusion container in predetermined positions on a tray placed on a work table of the drug filling unit, and then loads the tray into the co-infusion processing unit. This allows the co-infusion device of Patent Document 1 to start the co-infusion process.

[0003] Japanese Patent Application Laid-Open No. 2019-063313

[0004] However, in the co-infusion device of Patent Document 1, since the drug containers and the like must be placed at predetermined positions on the tray, the user has to take the trouble of filling the drug containers and the like into the co-infusion device.

[0005] An aspect of the present invention aims to reduce the user's effort involved in filling co-infusion equipment.

[0006] In order to solve the above problems, a co-infusion device according to one aspect of the present invention comprises a plurality of equipment holding units capable of holding co-infusion equipment to be used for co-infusion, and an equipment transport unit that transports at least one of the plurality of equipment holding units to a work area where a user causes at least one of the plurality of equipment holding units to hold the co-infusion equipment or where the user removes the co-infusion equipment held in the equipment holding unit, and the equipment transport unit transports another equipment holding unit in place of the equipment holding unit located in the work area in response to detection of a user's action or a user's transport instruction.

[0007] According to the co-infusion device of one aspect of the present invention, it is possible to reduce the user's effort involved in filling co-infusion equipment.

[0009] An embodiment of the present invention will be described in detail below. In each drawing, the X-axis and Y-axis are two mutually perpendicular axes in a horizontal plane (the contact 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, and the negative Y-axis direction as the front direction. The Z-axis is an axis extending 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.

[0010] [Overall Configuration of 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 and inspection unit 50, an infusion receiving section 60, a trash can section 70, a touch panel 80, and buttons 90.

[0011] The co-infusion device 1 is a device that performs a co-infusion process (co-infusion operation) of mixing a drug and an infusion. For example, the co-infusion device 1 performs the co-infusion process by using a syringe to aspirate a drug indicated in preparation data from a vial containing the drug and injecting the drug from the syringe into an infusion container (infusion bag). The syringe and the vial are examples of co-infusion equipment used for co-infusion and examples of injection equipment for injecting a drug into an infusion container.

[0012] Other examples of co-infusion processes include aspirating a drug from a vial using a syringe and injecting it into another vial, or aspirating an infusion liquid from an infusion container using a syringe and injecting it into a vial. When a vial contains a solid drug, the co-infusion device 1 uses a syringe to aspirate the infusion liquid from the infusion container and inject it into the vial. This allows the solid drug in the vial to become liquid. The co-infusion device 1 then uses the syringe to inject the liquid drug into the infusion container. The user may also directly perform the co-infusion process using the syringe, vial, and infusion container loaded in the co-infusion device 1.

[0013] The drug used in the co-infusion process may be, for example, a nutrient. The infusion solution used in the co-infusion process may be, for example, saline (physiological saline) or a liquid containing glucose. The infusion solution after drug injection may be, for example, a high-calorie infusion solution. In other words, the co-infusion device 1 of this embodiment mainly performs the co-infusion process using drugs with a low risk of radiation exposure. Therefore, as described below, the co-infusion device 1 has a relatively simple structure. That is, in the co-infusion device 1, for example, a user can load a syringe, vial, and infusion container into the co-infusion device 1 by opening and closing a door. With this configuration, the co-infusion device 1 can perform the co-infusion process more efficiently than co-infusion devices that mainly use drugs with a high risk of radiation exposure. However, the air purifying unit described below keeps the interior of the co-infusion device 1 clean, reducing the possibility of contamination of the drug and infusion solution during the co-infusion process. Furthermore, to keep the interior of the co-infusion device 1 clean, the interior of the co-infusion device 1 is maintained at positive pressure.

[0014] The preparation data is data for preparation generated based on the prescription data or the prescription data itself. The prescription data includes information such as the prescription issue date, patient ID, patient name, patient date of birth, drug information (drug code, drug name, dosage, etc.), dosage form information (oral or topical, etc.), usage information (three times a day after meals, etc.), medical treatment type (outpatient or inpatient, etc.), department, ward, and room. The preparation data also includes information such as patient information, doctor information, drug information, prescribed drug amount, drug container type, preparation content information, preparation procedure information, preparation date, prescription classification, administration date, department, ward, and preparation time. Examples of drug containers that contain the drugs include ampoules containing drug solutions, vials containing drug solutions, and vials containing powdered medicine. In this embodiment, a case where the drug container is a vial will be described as an example. The preparation content information includes the types and numbers of drug containers, syringes, and needles used in the mixed injection process. The preparation procedure information includes the work content, dissolving agent, solvent, amount of dissolving agent, amount of solvent, and amount extracted.

[0015] The syringe shelf 10 is an equipment storage shelf capable of storing syringes loaded in the co-infusion device 1. The syringe shelf 10 is provided with a syringe-side door 16 as an example of an equipment-side door. A user can hold a syringe on the syringe shelf 10 by opening and closing the syringe-side door 16.

[0016] The vial shelf 20 is an equipment storage shelf capable of storing vials filled in the co-infusion device 1. The vial shelf 20 is provided with a vial-side door 27 as an example of an equipment-side door. The user can hold a vial 502 on the vial shelf 20 by opening and closing the vial-side door 27.

[0017] The infusion shelf 30 is an infusion storage shelf capable of storing infusion containers filled in the co-infusion device 1. In this embodiment, the infusion shelf 30 includes an infusion shelf 30S and an infusion shelf 30L. The height of the infusion shelf 30L is greater than the height of the infusion shelf 30S. Therefore, the user can store infusion containers in the infusion shelf 30S or 30L according to the size of the infusion container. The infusion shelves 30S and 30L are also provided with infusion side doors 34S and 34L, respectively. The user can hold infusion containers in the infusion side doors 34S and 34L by opening and closing the infusion side doors 34S and 34L. The infusion side doors 34S and 34L can also be collectively referred to as the infusion side doors 34.

[0018] In this embodiment, the co-infusion device 1 is provided with a plurality of syringe shelves 10, vial shelves 20, and infusion shelves 30. Two syringe shelves 10 are provided in each row in the vertical direction. Three vial shelves 20 are provided in each row in the vertical direction. The syringe shelves 10 are provided in a higher row than the vial shelves 20. When the co-infusion device 1 is viewed from the front side of the co-infusion device 1, the infusion shelves 30 are provided on the opposite side of the syringe shelves 10, across the touch panel 80 provided near the center of the front surface. Three infusion shelves 30 are provided in each row in the vertical direction. The infusion shelf 30L is provided below the two infusion shelves 30S.

[0019] The syringe side door 16, the vial side door 27, and the infusion side doors 34S and 34L are doors that can block user access to the syringe shelf 10, the vial shelf 20, and the infusion shelves 30S and 30L, respectively. In the co-infusion device 1, the control unit 140 (see FIG. 5 ), which will be described later, controls so that only one of the syringe side door 16, the vial side door 27, and the infusion side doors 34S and 34L is open. As described above, the interior of the co-infusion device 1 is adjusted to a positive pressure. In the co-infusion device 1, by leaving only one door open, the possibility of the interior of the co-infusion device 1 being contaminated by gas outside the co-infusion device 1 can be reduced.

[0020] The button 90 is a mechanical button that can accept a user operation to open each of the syringe side door 16, the vial side door 27, and the infusion side door 34. One button 90 is provided for each of the syringe side door 16, the vial side door 27, and the infusion side door 34. When the syringe side door 16, the vial side door 27, and the infusion side door 34 are closed, they are locked by a locking mechanism (not shown). The syringe side door 16, the vial side door 27, and the infusion side door 34 are opened only when the user presses the button 90. However, when any of the syringe side door 16, the vial side door 27, and the infusion side door 34 is open, the closed door remains closed even if a user operation on the button 90 is accepted. In other words, when the control unit 140 (described later) opens any of the doors (unlocks it), it disables a user operation on the button 90 corresponding to the closed door.

[0021] The control unit 140 may lock only the doors of the syringe shelf 10, the vial shelf 20, or the infusion shelf 30 accessed by the first transport unit 110 or the second transport unit 120 described below. This configuration also reduces the possibility of a user touching the first transport unit 110 or the second transport unit 120 while the unit is in operation. Furthermore, it is possible to load syringes, vials, or infusion containers into unlocked shelves. This improves the efficiency of loading. Furthermore, light-emitting elements (not shown) may be provided corresponding to each of the syringe shelf 10, the vial shelf 20, and the infusion shelf 30. The control unit 140 can also reduce the possibility of a user touching the first transport unit 110 or the second transport unit 120 while the unit is in operation by illuminating the light-emitting elements corresponding to the shelves accessed by the first transport unit 110 or the second transport unit 120. In this case, a locking mechanism for each door is not necessarily required.

[0022] The printing and inspection unit 50 is a unit that prints a type information label (described later) and an unsuitable information label (described later) and affixes them to the infusion container after drug injection. The printing and inspection unit 50 is also a unit that weighs the infusion container after drug injection. In this embodiment, the printing and inspection unit 50 is provided below the infusion shelf 30L. Note that an infusion container after drug injection (after mixed injection processing) refers to an infusion container in which the drug is mixed with the infusion liquid. On the other hand, an infusion container before drug injection (before mixed injection processing) refers to an infusion container before the drug is mixed with the infusion liquid.

[0023] The infusion receiving unit 60 is a box that receives infusion containers with a type information label and / or an unsuitable information label affixed thereto after drug injection. In this embodiment, the infusion receiving unit 60 is provided below the printing / inspection unit 50. The trash can unit 70 is a box that receives used syringes. The touch panel 80 functions as an operation unit that receives various operations by the user and a display unit that displays various information. The operation unit and the display unit may be provided as separate components. Furthermore, instead of the display unit, a presentation unit (e.g., a speaker) that presents various information may be provided.

[0024] In this embodiment, a syringe side door 16, a vial side door 27, an infusion side door 34, a touch panel 80, and a button 90 are provided on the front side of the co-infusion device 1. This allows the user to access the syringe shelf 10, the vial shelf 20, the infusion shelf 30, and the button 90 from the side where the touch panel 80 is operated. In this embodiment, the printing / inspection unit 50, the infusion receiving section 60, and the trash can section 70 are also provided with handles on the front side of the co-infusion device 1, allowing the user to access them from the front side of the co-infusion device 1.

[0025] [Overview of the internal configuration and operation of the co-infusion device] Figure 2 is a cross-sectional view taken along line I-I in Figure 1. Figure 3 is a cross-sectional view taken along line II-II in Figure 1. As shown in Figures 2 and 3, the co-infusion device 1 includes a co-infusion unit 40, a first conveying section 110, a second conveying section 120 (infusion container conveying section), an air purifying section 130, and a pair of inclined sections 160. Note that the air purifying section 130 is not shown in Figure 2.

[0026] The co-infusion unit 40 functions as a mixer that mixes the drug with the infusion solution in the infusion container. In this embodiment, the co-infusion unit 40 is located opposite the syringe shelf 10 and the vial shelf 20, and is located at the back center of the co-infusion device 1. When preparation data (prescription data) is input, the first transport unit 110 is configured to transport syringes from the syringe shelf 10 to the co-infusion unit 40 and vials from the vial shelf 20 to the co-infusion unit 40. The second transport unit 120 is configured to transport infusion containers from the infusion shelf 30 to the co-infusion unit 40. These transports allow the co-infusion process to be performed in the co-infusion unit 40.

[0027] The first transport unit 110 grasps the upper part of the barrel of a syringe stored on the syringe shelf 10, moves leftward, and rotates 90 degrees on the XY plane to transport it to the co-infusion unit 40. Similarly, the first transport unit 110 grasps the barrel of a vial stored on the vial shelf 20, moves leftward, and rotates 90 degrees on the XY plane to transport it to the co-infusion unit 40.

[0028] Furthermore, the first transporting unit 110 transports the syringes stored in the syringe shelf 10 to a cap attaching / detaching unit 250 (see FIG. 11 ), which will be described later, before transporting them to the co-injection unit 40. This allows the first transporting unit 110 to remove the needle cap attached to the needle of the syringe, and to attach the syringe with the needle cap removed to the co-injection unit 40. Furthermore, the first transporting unit 110 transports the syringes and vials (syringes and vials that are no longer needed) after the co-injection process to a trash can unit 70.

[0029] The second transport unit 120 picks up the body of the infusion container stored on the infusion shelf 30, rotates it 90 degrees on the XY plane, and transports it to the co-infusion unit 40. The second transport unit 120 also picks up the body of the infusion container after drug injection and transports it to the printing and inspection unit 50, and transports the infusion container after drug injection with the type information label (and unsuitable information label) affixed to it to the infusion receiving unit 60.

[0030] 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.

[0031] The pair of inclined portions 160 allow the infusion container after drug injection to be transported from the second transport portion 120 to the infusion receiving portion 60 by the weight of the infusion container.

[0032] FIG. 4 illustrates an example of a pair of inclined portions 160. The pair of inclined portions 160 are guide members that guide the infusion container 503, which is adsorbed by the second transport unit 120 after drug injection, to the infusion receiving unit 60. As shown in FIG. 4 , the pair of inclined portions 160 are rod-shaped members that are inclined so that the end of the pair of inclined portions 160 is higher than the end of the infusion receiving unit 60. The second transport unit 120 operates to lock the neck of the infusion container 503 after drug injection between the pair of inclined portions 160, and then releases the adsorption state with respect to the body of the infusion container 503 after drug injection. As a result, the infusion container 503 after drug injection slides down the pair of inclined portions 160 under its own weight and is dispensed into the infusion receiving unit 60. In other words, the simple configuration of the pair of inclined portions 160 allows the infusion container 503 after drug injection to be dispensed into the infusion receiving unit 60 under its own weight.

[0033] The arrangement of each component in the co-infusion device 1 is not limited to the arrangement described above. For example, the vial shelf 20 may be provided on an upper level of the syringe shelf 10. The syringe shelf 10, vial shelf 20, and infusion shelf 30 may be arranged in the reversed positions. The syringe shelf 10, vial shelf 20, and infusion shelf 30 may all be arranged on either the left or right side of the co-infusion device 1, and the co-infusion unit 40 may be arranged in a different position from the syringe shelf 10, vial shelf 20, and infusion shelf 30. The syringe shelf 10, vial shelf 20, and infusion shelf 30 may not each be arranged in multiple levels, but may each be arranged in a single level. The positions of the printing / inspection unit 50 and the infusion receiving unit 60 may also be reversed. The arrangement of each component in the co-infusion device 1 may be determined taking into consideration user convenience, ease of manufacturing, and the like.

[0034] 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. As described below, one syringe and one vial are loaded from the front of the co-infusion device 1. On the other hand, multiple syringes or multiple vials can be loaded from the side of the co-infusion device 1. Therefore, by providing the syringe-side door 16 and / or the vial-side door 27 on the side of the co-infusion device 1, the user can load syringes and vials more efficiently. Note that, 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 of the co-infusion device 1. In this case, the user can load infusion containers more efficiently.

[0035] [Other Configurations] Fig. 5 is a block diagram showing an example of the overall configuration of the co-infusion device 1. As shown in Fig. 5, the co-infusion device 1 includes a control unit 140 and a storage unit 200. Note that Fig. 5 illustrates 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.

[0036] The control unit 140 controls the co-infusion device 1 overall. 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 / inspection unit control unit 148, a touch panel control unit 149, and a cap attachment / detachment control unit 150. The touch panel control unit 149 controls the touch panel 80. Other components of the control unit 140 will be described later along with an explanation of each component. The storage unit 200 stores various programs and various data used by the control unit 140. The specific configuration of the co-infusion device 1 will be described below, also with reference to FIG. 5 as appropriate.

[0037] [Configuration of the Co-infusion Unit] Fig. 6 is a diagram showing an example of the configuration of the co-infusion unit 40. As shown in Fig. 6, the co-infusion unit 40 includes a syringe holder 41, a vial holder 42, and an infusion container holder 43. The operation of each member of the co-infusion unit 40 is controlled by a co-infusion unit control unit 144 shown in Fig. 5.

[0038] The syringe holding portion 41 is a member that holds the syringe 501. The syringe 501 is composed of 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 to draw a medicine or the like into the syringe 5011 or to expel a medicine or the like from the syringe 5011. The syringe 5011 also includes a needle-side end portion 5012 to which the needle 5014 is attached, and a flange 5013, which is the end opposite the needle-side end portion 5012 and through which the plunger 5015 moves in and out. The vial holding portion 42 is a member that holds the vial 502. The infusion container holding portion 43 is a member that holds the infusion container 503. In this embodiment, the syringe holding portion 41 holds the lower portion of the barrel (syringe 5011) of the syringe 501. The syringe holding portion 41 also holds the syringe at the needle end portion 5012 and the flange 5013. The vial holding portion 42 and the infusion container holding portion 43 hold the neck portions of the vial 502 and the infusion container 503, respectively.

[0039] The syringe holding part 41 includes a pair of needle clamping parts 411, a syringe clamping part 412, a base part 415 (see FIG. 7 ), and a pair of first syringe holding parts 416. The base part 415 is a member provided with a pair of second syringe holding parts 413 (described later) and a pair of needle clamping parts 411. The base part 415 is provided so as to be movable in the up and down direction by the co-infusion unit control part 144.

[0040] The pair of needle clamping sections 411 are members that clamp the needle 5014. The pair of needle clamping sections 411 clamp the needle 5014 and position the tip of the needle 5014 at a predetermined position. This allows even a bent needle 5014 to be inserted into the desired position (correct position) of the stopper provided on the infusion container 503 during mixed injection processing. In addition, in this embodiment, the pair of needle clamping sections 411 function as electrodes. By causing the pair of needle clamping sections 411 to function as electrodes, the mixed injection unit control section 144 can detect a state in which a liquid (e.g., a drug or an infusion) is attached to one of the needle clamping sections of the pair of needle clamping sections 411. Specifically, when a liquid is attached to one or both of the two needle clamping sections constituting the pair of needle clamping sections 411, bringing the two needle clamping sections close to each other causes electrical conduction between the pair of needle clamping sections 411 via the liquid. The co-infusion unit control section 144 can detect the state in which liquid is attached to the pair of needle clamping sections 411 by detecting this conduction.

[0041] Here, if liquid is attached to the needle 5014, the liquid will adhere to the pair of needle clamping portions 411. Therefore, in this case, when the pair of needle clamping portions 411 subsequently holds the needle 5014 of another syringe 501, the liquid will adhere to the needle 5014. In other words, in this case, contamination occurs.

[0042] As shown in FIG. 5 , the co-infusion unit control unit 144 includes a liquid detection unit 1441. The liquid detection unit 1441 detects whether or not a liquid is attached to the pair of needle clamping units 411. Specifically, with the needle 5014 positioned between the two needle clamping units constituting the pair of needle clamping units 411, the co-infusion unit control unit 144 moves the two needle clamping units 411 closer to a position just before clamping the needle 5014 (a position slightly separated from the needle 5014). In this state, the liquid detection unit 1441 can detect whether or not a liquid is attached to the pair of needle clamping units 411 by determining whether or not conduction is detected between the pair of needle clamping units 411. When a liquid is attached to the pair of needle clamping units 411, the pair of needle clamping units 411 are electrically connected via the liquid. This allows the liquid detection unit 1441 to detect that a liquid is attached to the pair of needle clamping units 411. When the touch panel control unit 149 detects that liquid is adhering to the pair of needle clamping units 411, the touch panel control unit 149 may display on the touch panel 80 an image indicating that liquid is adhering to the pair of needle clamping units 411. In this case, the user can be prompted to clean the pair of needle clamping units 411. This reduces the possibility of the above-mentioned contamination occurring.

[0043] The co-infusion unit control unit 144 may bring the two needle clamping parts closer to the immediately preceding position before the first transporting unit 110 causes the syringe holding unit 41 to hold the syringe 501 (i.e., before positioning the needle 5014 between the two needle clamping parts). Even in this case, if liquid is attached to the pair of needle clamping parts 411, the pair of needle clamping parts 411 will be electrically connected via the liquid. Therefore, the liquid detection unit 1441 can detect that liquid is attached to the pair of needle clamping parts 411.

[0044] The pair of needle clamping portions 411 is an example of a needle holding portion that holds the needle 5014. In other words, the syringe holding portion 41 does not necessarily have to include the pair of needle clamping portions 411, but may include a member that holds the needle 5014. In this case, a pair of electrodes that are electrically connected when a liquid is attached to the pair of needle clamping portions 411 may be provided in addition to the pair of needle clamping portions 411. Note that when the term "pair of members" is used in this specification, the pair of members does not necessarily have to be a "pair" as long as the function of the member can be exhibited.

[0045] The pair of first syringe holding parts 416 are members that initially hold the syringe 501 that the first transport part 110 has transported from the syringe shelf 10. The pair of first syringe holding parts 416 sandwich the side surfaces of the syringe 5011 (e.g., the lower part of the syringe 5011) inserted into the pair of first syringe holding parts 416 from the left and right directions.

[0046] The syringe clamping portion 412 is a member that clamps the syringe 501 between the needle-side end portion 5012 and the flange 5013 along the extension direction of the syringe 501. Specifically, the syringe clamping portion 412 includes a pair of second syringe holding portions 413 and a pair of third syringe holding portions 414. The pair of second syringe holding portions 413 are an example of a syringe holding portion that holds the needle-side end portion 5012.

[0047] In the present embodiment, when the syringe 501 is held by the syringe clamping portion 412, the pair of second syringe holding portions 413 abut against the needle-side end portion 5012 from below, and the pair of third syringe holding portions 414 abut against the flange 5013 from above. This allows the syringe clamping portion 412 to clamp the syringe 501 along the extension direction of the syringe 501.

[0048] For example, when the pair of first syringe holding portions 416 clamp only the side surfaces of the syringe 5011, in order to fix the syringe 5011 so as not to slide in the extension direction of the syringe 501, it is necessary to apply a certain amount of force to clamp the syringe 5011. Therefore, there is a possibility that the syringe 5011 will be deformed by the force clamping the syringe 5011. By clamping the syringe 5011 along the extension direction of the syringe 501, the syringe clamping portions 412 can fix the syringe 5011 so as not to slide in the extension direction of the syringe 501 with a force smaller than when clamping the side surfaces of the syringe 5011. Therefore, the possibility of the syringe 5011 being deformed can be reduced.

[0049] The pair of second syringe holding portions 413 have a cone shape into which the needle-side ends 5012 can fit (see FIG. 7 ). The cross-sectional shape of the needle-side ends 5012 is either triangular with the needle attachment side as the apex or trapezoidal with the needle attachment side side shorter than the side on the syringe 5011 body side. Therefore, in the cross-sectional shape of the pair of second syringe holding portions 413, the portion inserted into the needle-side ends 5012 has a triangular shape with the apex on the lower side or a trapezoidal shape with the lower side shorter than the upper side, so that the pair of second syringe holding portions 413 can fit the needle-side ends 5012. Therefore, when the syringe clamping portion 412 clamps the syringe 501, the entire needle 5014 can protrude from the pair of second syringe holding portions 413. However, the shape of the pair of second syringe holding portions 413 is not limited to the above as long as it is a shape into which the needle-side ends 5012 can fit.

[0050] (Operation of Syringe Holding Unit) FIG. 7 is a diagram illustrating an example of the operation when the syringe 501 is held in the syringe holding unit 41. Reference numeral 7001 in FIG. 7 is a diagram illustrating a state in which the pair of first syringe holding units 416 hold the syringe 501. Reference numeral 7002 in FIG. 7 is a diagram illustrating a state in which the pair of second syringe holding units 413 hold the needle-side end unit 5012. Reference numeral 7003 in FIG. 7 is a diagram illustrating a state in which the pair of third syringe holding units 414 hold the flange 5013. Reference numeral 7004 in FIG. 7 is a diagram illustrating a state in which the pair of needle clamping units 411 clamp the needle 5014.

[0051] As indicated by reference numeral 7001 in Fig. 7 , the first transport unit 110 causes the pair of first syringe holding units 416 to hold the syringe 501 transported from the syringe shelf 10. In this state, the needle end portion 5012 is not engaged with the pair of second syringe holding units 413. Next, as indicated by reference numeral 7002 in Fig. 7 , the co-infusion unit control unit 144 moves the base 415 upward. As a result, the needle end portion 5012 engages with the pair of second syringe holding units 413.

[0052] With the needle-side end portions 5012 fitted into the pair of second syringe holding portions 413, the co-infusion unit control portion 144 moves the base portion 415 further upward. As a result, the pair of third syringe holding portions 414 come into contact with the flanges 5013 (the visor portions of the syringes 5011), as shown by reference numeral 7003 in Fig. 7 . In this state, the syringe clamping portion 412 clamps the syringe 501 between the needle-side end portions 5012 and the flanges 5013 along the extension direction of the syringe 501.

[0053] The co-infusion unit control section 144 may detect the force applied in the extension direction of the syringe 501. When the force applied in the extension direction of the syringe 501 becomes equal to or greater than a predetermined value, the co-infusion unit control section 144 can determine that the pair of third syringe holding sections 414 have come into contact with the flanges 5013 with the needle-side ends 5012 fitted in the pair of second syringe holding sections 413. The predetermined value may be determined in advance by experiment or the like.

[0054] When the co-infusion unit control section 144 determines that the force has reached or exceeded a predetermined value, it stops the upward movement of the base section 415. Thereafter, as shown by reference numeral 7004 in Fig. 7 , the co-infusion unit control section 144 moves the pair of needle clamping sections 411 toward the needle 5014, thereby causing the pair of needle clamping sections 411 to clamp the needle 5014.

[0055] (Process for detecting the contamination state of a pair of needle clamping portions) FIG. 8 is a flowchart showing an example of the process for detecting the contamination state of a pair of needle clamping portions 411. As shown in FIG. 8, the co-infusion unit control unit 144 determines that a pair of third syringe holding portions 414 abut against the flange 5013 when the needle-side end portions 5012 are fitted into a pair of second syringe holding portions 413. In this case, the co-infusion unit control unit 144 moves the two needle clamping portions constituting the pair of needle clamping portions 411 closer to the previous position described above (S1). Next, the liquid detection unit 1441 determines whether the pair of needle clamping portions 411 are electrically conductive (S2). If the liquid detection unit 1441 determines that the pair of needle clamping portions 411 are electrically conductive (YES in S1), the touch panel control unit 149 displays an image on the touch panel 80 to prompt the user to clean the pair of needle clamping portions 411 (S3). This reduces the possibility of contamination by encouraging the user to clean the pair of needle clamping parts 411. On the other hand, if the liquid detection unit 1441 determines that the pair of needle clamping parts 411 are not electrically connected (NO in S2), the needle is clamped by the pair of needle clamping parts 411 (S4).

[0056] As described above, in S1, the co-infusion unit control section 144 may bring the two needle clamping sections closer to the immediately preceding positions before the first conveying section 110 causes the syringe holding section 41 to hold the syringe 501. In this case, if the answer is NO in S2, the first conveying section 110 may cause the syringe holding section 41 to hold the syringe 501, and then cause the pair of needle clamping sections 411 to clamp the needle.

[0057] [Configuration of First Conveying Unit and Second Conveying Unit] (Configuration of First Conveying Unit) Fig. 9 is a diagram showing an example of the configuration of the first conveying unit 110. As shown in Fig. 9, the first conveying unit 110 includes a first claw portion 111, a second claw portion 112, and a rotating shaft portion 113. The operation of each member of the first conveying unit 110 is controlled by a first conveying control unit 143. In addition, the movement of the first conveying unit 110 between the syringe shelf 10 or the vial shelf 20 and the co-infusion unit 40 is also controlled by the first conveying control unit 143.

[0058] The first claw portion 111 and the second claw portion 112 are members that clamp the upper part of the syringe 5011 of the syringe 501 or the neck part of the vial 502, respectively. The first claw portion 111 and the second claw portion 112 may have any structure as long as they are able to hold the syringe 501 and the vial 502, respectively. However, in the present embodiment, the co-infusion unit 40 holds the lower part and both ends of the syringe 5011 of the syringe 501, and the body part of the vial 502. For this reason, in the present embodiment, the first conveying unit 110 is configured to grip the upper part of the syringe 5011 of the syringe 501 or the neck part of the vial 502. This makes it possible to differentiate the position where the co-infusion unit 40 clamps the syringe 501 or the vial 502 from both radial sides from the position where the first conveying unit 110 clamps the syringe 501 or the vial 502 from both radial sides. Therefore, even when the first conveying unit 110 is brought close to the first syringe holding unit 416, the first conveying unit 110 and the first syringe holding unit 416 do not come into contact with each other. Therefore, the first conveying unit 110 can bring the syringe 501 or the vial 502 close to the co-infusion unit 40, or can come close to the syringe 501 or the vial 502 held in the co-infusion unit 40. Therefore, the syringe 501 or the vial 502 can be efficiently transferred to and from the co-infusion unit 40. Furthermore, the rotating shaft 113 is a shaft that extends in the vertical direction, and rotates the first claw 111 and the second claw 112 on the XY plane.

[0059] The first conveying unit 110 is provided with the first claw 111 and the second claw 112, which enables efficient execution of the mixed injection process. For example, during a mixed injection process, the first conveying control unit 143 clamps the syringe 501 or vial 502 to be used in the next mixed injection process between the first claw 111 in order to transport it to the mixed injection unit 40. Thereafter, the first conveying control unit 143 receives the syringe 501 or vial 502 after the mixed injection process is completed from the mixed injection unit 40 and clamps it between the second claw 112 in order to transport it to the trash can 70. Thereafter, the first conveying control unit 143 transports the first conveying unit 110 to the mixed injection unit 40 with the first claw 111 holding the syringe 501 or vial 502. Therefore, the time required to transport the syringe 501 or vial 502 to the trash can section 70 and then hold the syringe 501 or vial 502 to be used in the next co-infusion process in the first transport section 110 and transport it to the co-infusion unit 40 can be shortened.

[0060] 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 to this. A transport unit dedicated to transporting the syringe 501 and a transport unit dedicated to transporting the vial 502 may be provided.

[0061] (Configuration of second conveying unit) Fig. 10 is a diagram showing an example of the configuration of the second conveying unit 120. As shown in Fig. 10, the second conveying unit 120 includes an adsorption unit 121 and a third reading unit 122. The operation of each member of the second conveying unit 120 is controlled by a second conveying control unit 145. In addition, the movement of the second conveying unit 120 between the co-injection unit 40 and the printing / inspection unit 50 is also controlled by the second conveying control unit 145.

[0062] The suction part 121 is configured to be able to suction the body 5031 of the infusion container 503. The second transporting part 120 may be configured to hold the infusion container 503. However, in the present embodiment, the mixing unit 40 holds the neck of the infusion container 503. Therefore, in the present embodiment, the second transporting part 120 is configured to be able to hold the body 5031 of the infusion container 503. This allows the holding position of the infusion container 503 when the mixing unit 40 holds the infusion container 503 to be different from the holding position of the infusion container 503 when the second transporting part 120 holds the infusion container 503. Therefore, even when the suction part 121 (infusion holding mechanism) of the second transporting part 120 is brought close to the infusion container holding part 43 (infusion holding mechanism) of the mixing unit 40, the infusion container holding part 43 and the suction part 121 do not come into contact with each other. Therefore, the second transport unit 120 can bring the infusion container 503 closer to the mixing unit 40 or approach the infusion container 503 held by the mixing unit 40. Therefore, the infusion container 503 can be efficiently transferred to and from the mixing unit 40.

[0063] The third reading unit 122 reads label information contained in an infusion label attached to the body 5031 of the infusion container 503. The label information read by the third reading unit 122 includes, for example, information indicating the type of infusion. If the label information is included in a barcode, the third reading unit 122 may be realized by a barcode reader.

[0064] 11 is a diagram showing an example of the configuration of the cap attaching / detaching unit 250. The cap attaching / detaching unit 250 attaches and detaches the needle cap 5016 of the syringe 501. The syringe 501 loaded in the syringe shelf 10 has the needle cap 5016 attached to the needle 5014.

[0065] As shown in FIG. 11 , in this embodiment, the cap attaching / detaching unit 250 includes a cap inserting unit 251, a pair of cap clamping units 252, and a solenoid 253. The cap inserting unit 251 has a needle cap 5016 attached to the needle 5014 of the syringe 501 inserted therein, and includes a member that presses the inserted needle cap 5016 toward the syringe 5011 using a spring (not shown). The pair of cap clamping units 252 clamp the needle cap 5016 under the control of the solenoid 253. The solenoid 253 controls the opening and closing of the pair of cap clamping units 252. The cap inserting unit 251 is provided with a spring (not shown), and the solenoid 253 is turned on when the spring is compressed to a predetermined length or less. As a result, the solenoid 253 closes the pair of cap clamping units 252. On the other hand, the solenoid 253 is turned off by the cap attachment / detachment control unit 150, thereby placing the pair of cap clamping units 252 in an open state.

[0066] FIG. 12 is a diagram showing the state when the cap attaching / detaching unit 250 removes the needle cap 5016 from the syringe 501. As indicated by reference numeral 12001 in FIG. 12 , the first transport unit 110 transports the syringe 501 removed from the syringe shelf 10 to the cap attaching / detaching unit 250. Then, as indicated by reference numeral 12002 in FIG. 12 , the first transport unit 110 inserts the needle cap 5016 of the syringe 501 into the cap attaching / detaching unit 250 (specifically, the cap insertion unit 251), and the needle cap 5016 pushes the spring-biased member against the biasing force of the spring. When the spring reaches a predetermined length or less, the solenoid 253 is turned on, and the pair of cap clamping units 252 enters a closed state. This causes the cap attaching / detaching unit 250 to clamp the needle cap 5016. 12 , the first transporting unit 110 moves away from the cap attaching / detaching unit 250. As a result, the needle cap 5016 is removed from the syringe 501. Therefore, the first transporting unit 110 can transport the syringe 501 from which the needle cap 5016 has been removed to the co-infusion unit 40.

[0067] Here, if the needle cap 5016 is simply clamped and removed from the needle 5014, there is a risk that the needle 5014 will move together with the needle cap 5016, and the needle 5014 will be removed from the syringe 5011. As described above, after the needle cap 5016 is pushed into the cap attaching / detaching unit 250, the cap attaching / detaching unit 250 clamps the needle cap 5016. By pushing the needle cap 5016 against the biasing force of the spring, the needle cap 5016 presses the needle 5014 present inside the needle cap 5016 toward the syringe 5011, and the needle 5014 fits into the syringe 5011 more firmly than the needle cap 5016. Therefore, when the needle cap 5016 is removed from the needle 5014, the needle 5014 can be prevented from being removed from the syringe 5011.

[0068] Note that the needle cap 5016 is pushed into the capping / removing unit 250 by the first transport unit 110 moving relative to the capping / removing unit 250, but this is not limiting. For example, the first transport unit 110 may stop just before or after inserting the needle cap 5016 into the capping / removing unit 250, and then the capping / removing unit 250 may move toward the first transport unit 110, thereby pushing the needle cap 5016 into the capping / removing unit 250.

[0069] The first conveying unit 110 also conveys the syringe 501 after the mixed injection process to the capping / removal unit 250, inserts the needle 5014 of the syringe 501 into the needle cap 5016 held by the capping / removal unit 250, and engages the needle 5014 with the needle cap 5016. In this state, the capping / removal control unit 150 turns off the solenoid 253, causing the pair of cap clamping units 252 to open. The first conveying unit 110 then moves away from the capping / removal unit 250. This allows the needle cap 5016 to be attached to the syringe 501 after the mixed injection process. Therefore, the first conveying unit 110 can discard the syringe 501 after the mixed injection process with the needle cap 5016 attached in the trash can unit 70.

[0070] [Configuration of Syringe Shelf] The detailed configuration of the syringe shelf 10 will be described below with reference to Figs. 13 to 16. Fig. 13 is a perspective view showing an example of the overall configuration of the syringe shelf 10 and the vial shelf 20. Fig. 14 is a perspective view showing an example of the configuration of one syringe shelf 10 and one vial shelf 20. Fig. 15 is a perspective view showing an example of the configuration of one syringe shelf 10 and one vial shelf 20 when viewed from a direction different from that shown in Fig. 14. Fig. 16 is a view showing an example of the configuration of one syringe shelf 10 and one vial shelf 20 when viewed from the first transport unit 110 side.

[0071] 13 to 15, the syringe shelf 10 comprises a plurality of instrument holding sections 11, an instrument transport section 12, an object detection section 13, a syringe detection section 14, a needle detection section 15, and a syringe detection section 17. Members related to the transport of syringes 501 in the syringe shelf 10 are controlled by a syringe transport control section 141. Note that an instrument holding section 11 is also attached to the attachment section 1211 of the instrument transport section 12 shown in FIG. 13, but this is not shown in the drawing.

[0072] Prior to the mixed injection process, the user loads the syringe 501 into the syringe shelf 10. The syringe 501 is loaded into the syringe shelf 10 with a needle cap 5016 attached to the needle 5014.

[0073] 13 and 14, in this embodiment, a plurality of holes 172 are formed in a plate-like member 171 that defines each syringe shelf 10. This allows, for example, air purified by the air purifying unit 130 (see FIG. 3) to flow efficiently from the top to the bottom of the co-infusion device 1. Therefore, the entire space within the co-infusion device 1 can be kept clean.

[0074] The multiple instrument holding parts 11 are members capable of holding syringes 501. In this embodiment, one instrument holding part 11 holds one syringe 501, but one instrument holding part 11 may hold multiple syringes 501. In this embodiment, as shown in Figure 16, the instrument holding part 11 comprises a pair of free rollers 1111 and a pair of instrument clamping parts 1112.

[0075] The pair of instrument clamping parts 1112 clamp the syringe 501. In this embodiment, the pair of instrument clamping parts 1112 clamp the flange 5013 of the syringe 501. This allows the instrument holding part 11 to hold the neck part of the syringe 501. Furthermore, in this embodiment, the pair of instrument clamping parts 1112 are provided on the upper part of the syringe shelf 10. This allows the syringe 501 to be held in the instrument holding part 11 so that the needle cap 5016 (needle 5014) is located on the lower side. The pair of instrument clamping parts 1112 are provided at a height such that the syringe 501 does not come into contact with the plate-like member 171 when the syringe 501 is held in the instrument holding part 11.

[0076] In this embodiment, in the co-infusion unit 40, the syringe 501 is arranged so that the needle 5014 is located on the lower side. Therefore, the pair of instrument clamping sections 1112 are provided on the upper part of the syringe shelf 10. Note that, taking this point into consideration, the cap attaching / detaching section 250 (see FIG. 11 ) is also arranged on the lower part of the co-infusion device 1 so that the cap insertion section 251 faces upward. However, for example, when the syringe 501 is arranged on the co-infusion unit 40 so that the needle 5014 is located on the upper side, the pair of instrument clamping sections 1112 may be provided on the lower part of the syringe shelf 10. Furthermore, the cap attaching / detaching section 250 may also be arranged on the upper part of the co-infusion device 1 so that the cap insertion section 251 faces downward.

[0077] The pair of instrument clamping parts 1112 are biased in directions moving towards each other so that they can clamp the syringe 501. In this embodiment, the pair of instrument clamping parts 1112 are spaced apart by a distance smaller than the width of the flange 5013 when not clamping the flange 5013. When the flange 5013 is inserted between the pair of instrument clamping parts 1112, the pair of instrument clamping parts 1112 move in accordance with the shape of the flange 5013. This allows the pair of instrument clamping parts 1112 to clamp the syringe 501.

[0078] A pair of free rollers 1111, which have a rotation axis extending in the vertical direction and are rotatable on the XY plane, are provided below the tips of the pair of instrument clamping parts 1112. The pair of free rollers 1111 hold the vicinity of the flange 5013 of the syringe 5011 clamped by the pair of instrument clamping parts 1112.

[0079] The instrument transport unit 12 is a member that transports at least one of the multiple instrument holders 11 to the working area Ar1. In this embodiment, the instrument transport unit 12 is an endless rotating member to which multiple instrument holders 11 are connected. Therefore, in this embodiment, the instrument transport unit 12 transports the instrument holders 11 one by one to the working area Ar1. However, the instrument transport unit 12 may also be a transport unit that transports multiple instrument holders 11 to the working area Ar1 at one time.

[0080] Here, the work area Ar1 is an area where a user causes at least one of the plurality of instrument holding units 11 to hold a syringe 501, and where the user removes the syringe 501 held in at least one of the plurality of instrument holding units 11. That is, the work area Ar1 functions as a filling location where a syringe 501 can be filled, and also functions as a recovery location where a syringe 501 can be recovered. In this embodiment, the work area Ar1 is an area where a user causes one instrument holding unit 11 to hold a syringe 501, and where the user removes the syringe 501 held in one instrument holding unit 11. Furthermore, in this embodiment, the work area Ar1 is located on the syringe-side door 16 side shown in FIG. 1 . This allows the user to fill the instrument holding unit 11 with the syringe 501 and remove the syringe 501 held in the instrument holding unit 11 from the syringe-side door 16 side. The syringe side door 16 functions as a door that can block the user's access to the work area Ar1.

[0081] The working area Ar1 may function only as an area where the user causes at least one of the plurality of instrument holders 11 to hold the syringe 501. In this case, the area where the user removes the syringe 501 held in the instrument holder 11 may be provided in a position separate from the working area Ar1. The working area Ar1 may also function only as an area where the user removes the syringe 501 held in the instrument holder 11. In this case, the area where the user causes the syringe 501 to be held in the instrument holder 11 may be provided in a position separate from the working area Ar1.

[0082] Furthermore, in this embodiment, the instrument transport unit 12 transports another instrument holding unit 11 in place of the instrument holding unit 11 located in the working area Ar1 in response to detection of a user's movement. The instrument transport unit 12 changes the instrument holding unit 11 located in the working area Ar1, for example by rotating counterclockwise. This transport operation allows another instrument holding unit 11 not holding a syringe 501 to be transported to the working area Ar1, replacing the instrument holding unit 11 holding the syringe 501 in the working area Ar1. Therefore, the user only needs to place the syringe 501 in the instrument holding unit 11 transported to the working area Ar1. This reduces the user's effort required for filling the syringe 501.

[0083] Specifically, the instrument transport unit 12 transports another instrument holder 11 to 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, triggering the transport unit 12 to transport another instrument holder 11 to the working area Ar1. In this case, the user inserts their hand into the working area Ar1, holds the syringe 501 in the instrument holder 11, and then when the user's hand leaves the working area Ar1, the instrument transport unit 12 transports another instrument holder 11 to the working area Ar1. Therefore, the instrument transport unit 12 can transport another instrument holder 11 to the working area Ar1 without the user issuing a transport instruction to the co-infusion device 1. This further reduces the user's effort in filling the syringe 501. Furthermore, the instrument transport unit 12 does not transport another instrument holder 11 to the working area Ar1 until the user's hand leaves the working area Ar1, i.e., while the user's hand is present in the working area Ar1. Therefore, the safety of the user involved in the filling operation of the syringe 501 can be ensured.

[0084] Furthermore, in this embodiment, the instrument transporting unit 12 transports another instrument holding unit 11 to the working area Ar1 when the syringe detection unit 14 detects a syringe 501 held in an instrument holding unit 11, in addition to detecting the user's movement. Therefore, the instrument transporting unit 12 can transport another instrument holding unit 11 to the working area Ar1 after the user has caused an instrument holding unit 11 located in the working area Ar1 to hold a syringe 501. This reduces the possibility that the instrument transporting unit 12 will transport another instrument holding unit 11 to the working area Ar1 without causing the instrument holding unit 11 to hold a syringe 501.

[0085] The object detection unit 13 is a component that detects an object inserted into the work area Ar1. In the present embodiment, the object detection unit 13 detects the user's hand or arm inserted in the work area Ar1. The object detection unit 13 uses the side of the syringe shelf 10 where the syringe side door 16 shown in FIG. 1 is provided (the front side of the co-infusion device 1) as the object detection area when viewed from the instrument transport unit 12. Specifically, the object detection unit 13 is provided in a position corresponding to the area between the syringe side door 16 and the instrument holding unit 11 located in the work area Ar1 on the wall constituting the syringe shelf 10. In addition, in the present embodiment, in order to improve the detection accuracy of an object in the work area Ar1, multiple object detection units 13 are provided along the vertical direction of the syringe shelf 10. The object detection unit 13 may be, for example, an optical sensor configured with an emission unit that emits light and a light receiving unit that is provided in a position opposite the emission unit and receives light from the emission unit. In this case, when the light receiving unit is not receiving light, the object detection unit 13 detects an object. However, the object detection unit 13 may be any type of sensor as long as it can detect an object inserted into the working area Ar1. This also applies to other detection units (sensors). For example, when the object detection unit 13 detects an object, it outputs a detection signal to the control unit 140 while it is detecting the object.

[0086] The syringe detection unit 14 is a component that detects the syringe 501 held in the instrument holding unit 11 located in the work area Ar1. In other words, the syringe detection unit 14 functions as an instrument detection unit that detects an injection instrument held in the instrument holding unit 11 located in the work 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. As shown in FIGS. 13 and 14 , the syringe detection unit 14 is provided on a wall that constitutes the syringe shelf 10, at a position facing the instrument holding unit 11 located in the work area Ar1. The syringe detection unit 14 may be, for example, an optical sensor that detects an object by emitting light and receiving light reflected by the object. For example, when the syringe detection unit 14 detects the syringe 5011, it outputs a detection signal to the control unit 140.

[0087] The needle detection unit 15 detects the needle 5014 of the syringe 501 held in the instrument holder 11 located in the work area Ar1. In this embodiment, the needle detection unit 15 detects the needle cap 5016 attached to the needle 5014. As shown in FIGS. 13 and 14 , the needle detection unit 15 is provided in a position facing the instrument holder 11 located in the work area Ar1 on a wall portion constituting the syringe shelf 10. In this embodiment, the needle detection unit 15 is arranged in the same vertical row as the syringe detection unit 14, but this does not necessarily have to be the case. The needle detection unit 15 may be, for example, an optical sensor similar to the syringe detection unit 14. Note that the needle detection unit 15 may also function as the syringe detection unit. In this case, the syringe detection unit 14 may not be provided. For example, when the needle detection unit 15 detects the needle cap 5016, it outputs a detection signal to the control unit 140.

[0088] In addition, multiple needle detection units 15 may be provided in the wall section in the vertical direction at predetermined intervals. In this case, the control unit 140 can estimate the length of the needle 5014 attached to the syringe 501 held in the instrument holding unit 11 based on whether or not the needle cap 5016 is detected by each of the multiple needle detection units 15. Therefore, the control unit 140 can determine whether the needle 5014 is appropriate for attachment to the syringe 501 held in the instrument holding unit 11. If the control unit 140 determines that the needle 5014 is unsuitable for attachment to the syringe 501, the touch panel control unit 149 may display an image indicating this unsuitability on the touch panel 80. In addition, information indicating whether or not each needle detection unit 15 detected the needle 5014 and the length of the needle 5014, as well as information indicating the thickness (diameter) of the syringe 501 and the length of the needle 5014, may be stored in the memory unit 200. Furthermore, a plurality of needle detectors for detecting the length of the needle 5014 may be provided separately from the needle detector 15 .

[0089] The syringe detection unit 17 is a member capable of detecting the thickness of the syringe 5011. The syringe detection unit 17 is provided in a wall portion constituting the syringe shelf 10 at a position where it can detect the syringe 5011 being transported by the instrument transport unit 12. The syringe detection unit 17 may be provided, for example, so that the detection area of ​​the object by the syringe detection unit 17 is inclined with respect to the XY plane. The syringe detection unit 17 may be, for example, an optical sensor similar to the syringe detection unit 14. Note that the syringe detection unit 17 may also function as the syringe detection unit. In this case, the syringe detection unit 14 may not be provided.

[0090] For example, when the syringe detection unit 17 detects a syringe 5011, it outputs a detection signal to the control unit 140 while it is detecting the syringe 5011. The memory unit 200 stores information indicating the speed of the instrument transport unit 12 in front of the syringe detection unit 17 and information indicating the diameters of various syringes 5011 that can be used in the co-infusion device 1. The control unit 140 calculates the detection time of the syringe 5011 by the syringe detection unit 17, and then multiplies the detection time by the speed of the instrument transport unit 12 to calculate the diameter of the syringe 5011 that has passed in front of the syringe detection unit 17. This allows the control unit 140 to identify the diameter of the syringe 5011 that has passed in front of the syringe detection unit 17 (i.e., the type of syringe 501). Therefore, the control unit 140 can determine, for example, whether the syringe 501 held in the instrument holding unit 11 is appropriate as the syringe 501 to be used for aspirating the medicine indicated in the preparation data (the syringe 501 to be loaded into the syringe shelf 10). If the control unit 140 determines that the syringe 501 held in the instrument holding unit 11 is unsuitable as the syringe 501 to be used for aspirating the medicine, the touch panel control unit 149 may display an image indicating this unsuitability on the touch panel 80. Note that information indicating the type of syringe 501 to be used for aspirating the medicine indicated in the preparation data may be stored in the storage unit 200 together with the preparation data.

[0091] Furthermore, for example, the memory unit 200 may store, in association with each other, information identifying each instrument holding unit 11, information indicating the type of syringe 501 held in each instrument holding unit 11, and information indicating the transport position of each instrument holding unit 11. In this case, the first transport control unit 143 can identify the type of syringe 501 that the first transport unit 110 will remove from the instrument holding unit 11. Therefore, the first transport unit 110 can transport an appropriate syringe 501 to the co-infusion unit 40.

[0092] (Transport start processing of the instrument holding unit) Fig. 18 is a flowchart showing an example of processing when starting the transport of the instrument holding unit 11. Reference numeral 18001 in Fig. 18 is a flowchart showing an example of processing when the syringe transport control unit 141 starts the transport of the instrument holding unit 11.

[0093] 18 , the syringe transport control unit 141 determines whether or not the user's hand inserted into the working area Ar1 has been detected by the object detection unit 13 (S101). The syringe transport control unit 141 determines that the user's hand has been detected when it receives a detection signal from the object detection unit 13. When the syringe transport control unit 141 determines that the user's hand has not been detected (NO in S101), it continues the processing of S101.

[0094] When the syringe transport control unit 141 determines that the user's hand has been detected (YES in S101), it determines whether the syringe 5011 has been detected by the syringe detection unit 14 (S102). When the syringe transport control unit 141 receives a detection signal from the syringe detection unit 14, it determines that the syringe 5011 has been detected.

[0095] When the syringe transport control unit 141 determines that the syringe 5011 has been detected (YES in S102), it determines whether or not the needle 5014 has been detected by the needle detection unit 15 (S103). When the syringe transport control unit 141 receives a detection signal from the needle detection unit 15, it determines that the needle 5014 has been detected.

[0096] When the syringe transport control unit 141 determines that the needle 5014 has been detected (YES in S103), it determines whether the user's hand inserted in the working area Ar1 has become undetected (S104). The syringe transport control unit 141 determines that the user's hand has become undetected, for example, when reception of the detection signal that was continuously received from the object detection unit 13 in S101 is discontinued. When the syringe transport control unit 141 determines that the user's hand has not become undetected (NO in S104), it returns to the processing of S102.

[0097] When the syringe transport control unit 141 determines that the user's hand has not been detected (YES in S104), it controls the equipment transport unit 12 to transport another equipment holding unit 11 to the work area Ar1 instead of the equipment holding unit 11 located in the work area Ar1 (S105).

[0098] Note that even if the syringe side door 16 is in the open state, if it is determined in S104 that the user's hand has not been detected, the syringe transport control unit 141 may transport the instrument holding unit 11 by controlling the instrument transport unit 12. The co-infusion device 1 is equipped with a detection unit that detects whether the syringe side door 16 is open or closed, and the syringe transport control unit 141 can determine whether the syringe side door 16 is open or closed by receiving a detection signal from the detection unit. Furthermore, if syringes 501 are held in all the instrument holding units 11, the syringe transport control unit 141 does not need to transport the instrument holding unit 11.

[0099] Furthermore, when it is determined in S102 that the syringe 5011 has not been detected (NO in S102), the syringe transport control unit 141 determines whether or not a predetermined time has elapsed since the syringe 5011 was not detected (S107). Specifically, the syringe transport control unit 141 determines whether or not a predetermined time has elapsed since no detection signal was received from the syringe detection unit 14. The counting of the predetermined time may be started, for example, when a detection signal is received from the object detection unit 13. Furthermore, the predetermined time may be set to, for example, a time appropriate for ending this process.

[0100] If the syringe transport control unit 141 determines that the syringe 5011 has remained undetected for a predetermined time period (YES in S107), it terminates this process. On the other hand, if the syringe transport control unit 141 determines that the syringe 5011 has remained undetected for a predetermined time period (NO in S107), it continues the process of S102.

[0101] Furthermore, if the syringe transport control unit 141 determines in S103 that the needle 5014 has not been detected (NO in S103), the touch panel control unit 149 displays an image indicating that there is no needle on the touch panel 80 (S106). This allows the user to recognize syringes 501 that are unsuitable for mixed injection processing. Note that the processes of S102 and S103 do not necessarily have to be executed.

[0102] (Modification) In the present embodiment, as described above, the syringe transport control unit 141 changes the instrument holding unit 11 located in the work area Ar1 to another instrument holding unit 11 when the object detection unit 13 detects a user's hand and then stops detecting the user's hand as a trigger. However, this is not limited to this, and for example, the syringe transport control unit 141 may transport another instrument holding unit 11 instead of the instrument holding unit 11 located in the work area Ar1 as a trigger for a transport instruction from the user. The syringe transport control unit 141 may accept the user's transport instruction via the touch panel 80, for example.

[0103] [Configuration of Vial Shelf] The detailed configuration of the vial shelf 20 will be described below with reference to Figures 13 to 17. Figure 17 is a diagram for explaining the instrument holder 21.

[0104] As shown in Figures 13 to 15, the vial shelf 20 comprises a plurality of instrument holders 21, an instrument transport unit 22, an object detector 23, and a vial detector 24. As shown in Figures 16 and 17, the vial shelf 20 also comprises a first reader 25 (reader) and a roller driver 26. The components of the vial shelf 20 that are involved in the transport of vials 502 are controlled by a vial transport controller 142. Note that an instrument holder 21 is also attached to the mounting portion 221 of the instrument transport unit 22 shown in Figure 13, but this is not shown in the figure.

[0105] Prior to the mixed injection process, the user fills the vial shelves 20 with vials 502. Similar to the syringe shelves 10, a plurality of holes 172 are formed in the plate-like members 171 that define each vial shelf 20.

[0106] The instrument holder 21 is a member capable of holding a vial 502. In this embodiment, one instrument holder 21 holds one vial 502, but one instrument holder 21 may hold multiple vials 502.

[0107] In this embodiment, as shown in FIGS. 16 and 17, the object holder 21 comprises a pair of free rollers 211, a pair of object clamping parts 212, a drive roller 213, and a first magnet 214.

[0108] The pair of instrument clamping parts 212 clamp the vial 502. In this embodiment, the pair of instrument clamping parts 212 clamp the neck of the vial 502. In this embodiment, the pair of instrument clamping parts 212 are provided above the vial shelf 20. The pair of instrument clamping parts 212 are provided at a height such that the vial 502 does not come into contact with the plate-like member 171 when the vial 502 is held by the instrument holding part 21.

[0109] The pair of instrument clamping parts 212 are biased in directions that move them toward each other so that they can clamp the vial 502. In this embodiment, the pair of instrument clamping parts 212 are spaced apart by a distance smaller than the width of the neck of the vial 502 when not clamping the neck. When the neck is inserted between the pair of instrument clamping parts 212, the pair of instrument clamping parts 212 move in accordance with the shape of the neck. This allows the pair of instrument clamping parts 212 to clamp the vial 502.

[0110] A pair of free rollers 211, which have a rotation axis extending in the vertical direction and are rotatable on the XY plane, are provided at the tips of the pair of instrument clamping parts 212. The pair of free rollers 211, together with a drive roller 213 provided on the side where the pair of instrument clamping parts 212 are axially supported and positioned opposite the center of the pair of free rollers 211, support the neck of the vial 502 at three points, thereby holding the vial 502. When the drive roller 213 rotates while holding the vial 502, the vial 502 also rotates. This rotation also rotates the pair of free rollers 211. By providing a pair of free rollers 211 at the tips of the pair of instrument clamping parts 212, it is possible to reduce the possibility that the rotational force of the vial 502 will be reduced by the tips.

[0111] A first magnet 214 is provided above the drive roller 213. The drive roller 213 and the first magnet 214 are connected to a common rotation axis extending in the vertical direction and are rotatable on the XY plane. The first magnet 214 rotates in conjunction with the rotation of the second magnet 261 provided in the roller drive unit 26, thereby causing the drive roller 213 to rotate. In this embodiment, south poles and north poles are arranged alternately on the outer circumferential surfaces of the first magnet 214 and the second magnet 261.

[0112] The instrument transport unit 22 transports at least one of the multiple instrument holders 21 to the work area Ar2. In this embodiment, the instrument transport unit 22 is an endless rotating member to which multiple instrument holders 21 are connected. Therefore, in this embodiment, the instrument transport unit 22 transports the instrument holders 21 one by one to the work area Ar2. However, the instrument transport unit 22 may also be a transport unit that transports multiple instrument holders 21 to the work area Ar2 at once. Similarly to the work area Ar1, the work area Ar2 is an area where the user places a vial 502 in at least one of the multiple instrument holders 21. The work area Ar2 is also an area where the user removes a vial 502 held in at least one of the multiple instrument holders 21. In this embodiment, the work area Ar2 is located on the side of the vial-side door 27 shown in FIG. 1 . The vial-side door 27 functions as a door that can block a user's access to the working area Ar2. Similarly to the working area Ar1, the working area Ar2 may function only as an area for holding the vial 502 or an area for removing the vial 502.

[0113] In this embodiment, the instrument transport unit 22 has the same functions as the instrument transport unit 12 described below. That is, when the instrument transport unit 22 detects a user's movement, it transports another instrument holder 21 in place of the instrument holder 21 located in the working area Ar2. The instrument transport unit 12 changes the instrument holder 21 located in the working area Ar2, for example, by rotating counterclockwise. When the object detection unit 23 detects the user's movement as described above, the instrument transport unit 22 transports another instrument holder 11 to the working area Ar2. Furthermore, in this embodiment, when the vial detection unit 24 detects a vial 502 held in the instrument holder 21 in addition to detecting a user's movement, the instrument transport unit 22 transports another instrument holder 11 to the working area Ar2. With this configuration, the instrument transport unit 22 can achieve the same effects as the instrument transport unit 12.

[0114] Similarly to the syringe transport controller 141, the vial transport controller 142 may transport another instrument holder 21 in place of the instrument holder 21 located in the working area Ar2, for example, in response to a transport instruction from the user. The vial transport controller 142 may receive the transport instruction from the user via the touch panel 80, for example.

[0115] The vial 502 is provided with a rubber stopper that closes the opening and a lid that fits over the rubber stopper. The needle of the syringe 501 held in the co-infusion unit 40 is punctured into the rubber stopper. The vial 502 is loaded into the vial shelf 20 with the lid removed. For example, a camera (not shown) may be provided on the vial shelf 20, and the camera may capture an image of the top of the vial 502. In this case, the control unit 140 can determine the presence or absence of a lid based on the image captured by the camera. If a lid is attached to the vial 502, the touch panel control unit 149 may display an image on the touch panel 80 that prompts the user to load the vial 502 into the instrument holding unit 21 with the lid removed.

[0116] The object detection unit 23 is a component 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 arrangement of the object detection unit 23 in the vial shelf 20 is similar to the arrangement of the object detection unit 13 in the syringe shelf 10, and the specific examples and functions of the object detection unit 23 are also similar to those of the object detection unit 13.

[0117] The vial detection unit 24 detects the vials 502 held in the instrument holders 21 located in the work area Ar2. In other words, the vial detection unit 24 functions as an instrument detection unit that detects the syringe instruments held in the instrument holders 21 located in the work area Ar2. The arrangement of the vial detection units 24 on the vial shelf 20 is the same as the arrangement of the syringe detection units 14 on the syringe shelf 10, and the specific examples and functions of the vial detection units 24 are also the same as those of the syringe detection unit 14.

[0118] The first reading unit 25 is a component that reads type information indicating the type of drug contained in the vial 502, which is displayed on the surface of the vial 502, along a part of the transport path along which the instrument transport unit 22 transports the multiple instrument holders 21. The vial 502 may be affixed with a barcode on which the type information is recorded. In this case, the first reading unit 25 may be a barcode reader.

[0119] 16 and 17 , the first reading unit 25 is disposed at a position where it can read the barcode of the vial 502 transported to the predetermined position. In the present embodiment, the predetermined position may be the position where the first transporting unit 110 removes the vial 502. By reading the barcode at the position where the vial 502 is removed in this manner, the control unit 140 can recognize the type of drug contained in the vial 502 immediately before removal. Therefore, the first transporting unit 110 can transport an appropriate vial 502 to be transported to the co-infusion unit 40. Note that in the present embodiment, the first reading unit 25 is disposed behind the predetermined position when the vial shelf 20 is viewed from the first transporting unit 110 side.

[0120] In this embodiment, the first reading unit 25 starts reading the barcode of the vial 502 when the vial-side door 27 is closed. The control unit 140 starts the reading operation by the first reading unit 25 when it detects that the vial-side door 27 is closed. With this configuration, if a user has multiple instrument holders 21 each holding a vial 502, the barcode (type information) indicated on each of the multiple vials 502 can be read sequentially when the vial-side door 27 is closed. This allows the first reading unit 25 to read barcodes efficiently.

[0121] When the instrument transport unit 22 detects that the vial-side door 27 has been closed, if the vial 502 is not present at the barcode reading position by the first reading unit 25, the instrument transport unit 22 may transport the vial 502 to that position. After the first reading unit 25 has completed reading the barcode of the vial 502, the instrument transport unit 22 may transport the next vial 502 to the above position so that the first reading unit 25 can read the barcode of the next vial 502.

[0122] 17, the roller drive unit 26 is a motor that rotates a second magnet 261 attached to the roller drive unit 26 in order to rotate the drive roller 213 of the instrument holder 21. The rotation axis of the roller drive unit 26 extends in the Y-axis direction, and the second magnet 261 is attached to this rotation axis. This allows the second magnet 261 to rotate on the XZ plane. The vial transport control unit 142 may drive the roller drive unit 26, for example, when the vial 502 is positioned at a barcode reading position by the first reading unit 25.

[0123] As described above, the first magnet 214 of the instrument holder 21 is disposed on the upper part of the instrument holder 21. The positions of the instrument holder 21 and the roller drive unit 26 are determined so that the first magnet 214 and the second magnet 261 are spaced apart by a distance that allows them to receive each other's magnetic force.

[0124] When the vial transport control unit 142 drives the roller drive unit 26, the second magnet 261 also rotates. The first magnet 214 rotates in conjunction with the rotation of the second magnet 261. The drive roller 213, which is connected to the same rotation axis as the first magnet 214, rotates in conjunction with the rotation of the first magnet 214, causing the vial 502 in contact with the drive roller 213 to rotate. By rotating the vial 502 in this manner, the first reading unit 25 can read the barcode no matter where the barcode is located on the surface of the vial 502.

[0125] The first reading unit 25 may start reading the barcode of the vial 502 in response to a reading instruction from the user. The control unit 140 may accept the reading instruction from the user via the touch panel 80, for example.

[0126] (Transport Start Processing of the Object Holding Unit) Reference numeral 18002 in FIG. 18 is a flow chart showing an example of processing when the vial transport control unit 142 starts transport of the object holding unit 21.

[0127] As indicated by reference numeral 18002 in FIG. 18, similar to S101 of reference numeral 18002, the vial transport control unit 142 determines whether or not a user's hand inserted into the working area Ar2 has been detected (S201).

[0128] When the vial transport control unit 142 determines that the user's hand has been detected (YES in S201), it determines whether the vial detection unit 24 has detected the vial 502 (S202). When the vial transport control unit 142 receives a detection signal from the vial detection unit 24, it determines that the vial 502 has been detected.

[0129] When the vial transport control unit 142 determines that the syringe 5011 has been detected by the vial detection unit 24 (YES in S202), it determines whether the user's hand inserted into the working area Ar2 has been undetected (S204), similar to S104 of reference numeral 18001.

[0130] If the vial transport control unit 142 determines that the user's hand has not been detected (YES in S204), it controls the equipment transport unit 22 to transport another equipment holding unit 21 to the work area Ar2 instead of the equipment holding unit 21 located in the work area Ar2 (S205).

[0131] If the vial transport control unit 142 determines in S202 that the vial 502 has not been detected (NO in S202), it determines whether the vial 502 has remained undetected for a predetermined time (S205), similar to S107 of reference numeral 18001.

[0132] (Other Processing) For example, the following processing may be performed to improve the filling efficiency of the vials 502 held in the instrument holding part 21. Figure 19 is a diagram for explaining the improvement of filling efficiency of the vials 502 held in the instrument holding part 21. Note that the filling efficiency example described below may also be applied to the improvement of filling efficiency of the syringes 501 held in the instrument holding part 11.

[0133] (Filling efficiency improvement example 1) Reference numeral 19001 in Fig. 19 shows a state in which two instrument holders 21 that do not hold vials 502 are located at different positions. Reference numeral 19002 in Fig. 19 shows a state in which two instrument holders 21 that do not hold vials 502 are located at adjacent positions.

[0134] A situation may occur in which two or more of the multiple instrument holding sections 21 do not hold any vials 502. An instrument holding section 21 that does not hold any vials 502 can also be referred to as an empty instrument holding section 21. Furthermore, when two or more empty instrument holding sections 21 occur, there is a possibility that at least two of the empty instrument holding sections 21 are located in positions that are not adjacent to each other. This situation may occur, for example, when the first transport section 110 transports vials 502 to be used in a mixed injection process to the mixed injection unit 40. In the example shown by reference numeral 19001 in Figure 19, there are two empty instrument holding sections 21, and these empty instrument holding sections 21 are located in positions that are not adjacent to each other.

[0135] For example, the memory unit 200 may store, in association with each other, information identifying each instrument holding unit 21, information indicating the type of drug contained in the vial 502 held in each instrument holding unit 21, and information indicating the transport position of each instrument holding unit 21. For example, if information identifying an instrument holding unit 21 is not associated with information indicating the type of drug, the control unit 140 may determine that the instrument holding unit 21 is an empty instrument holding unit 21. Furthermore, the control unit 140 may determine whether two empty instrument holding units 21 are adjacent to each other based on the information identifying the instrument holding units 21.

[0136] If the control unit 140 determines that two empty instrument holders 21 are not adjacent, it executes the following process, for example, during idle time of the first transport unit 110. As shown by reference numeral 19002 in FIG. 19 , the control unit 140 moves the vial 502 held in the instrument holder 21 so that the empty instrument holder 21 is adjacent. For example, under the control of the vial transport control unit 142, the instrument transport unit 22 transports the instrument holder 21 located adjacent to the empty instrument holder 21 to a position from which the first transport unit 110 will remove the vial 502. Under the control of the first transport control unit 143, the first transport unit 110 removes and holds the vial 502. This brings the two empty instrument holders 21 into a state where they are adjacent to each other. In this state, the instrument transport unit 22 transports the other empty instrument holder 21 to a position from which the first transport unit 110 will remove the vial 502. The first transport unit 110 causes the empty instrument holder 21 to hold the vial 502 it is holding.

[0137] In the case of reference numeral 19001 in Figure 19, consider the case where a vial 502 is filled into an empty instrument holder 21 in the working area Ar2, and then another vial 502 is filled into another empty instrument holder 21. In this case, the instrument transport unit 22 must move another empty instrument holder 21 that is located away from the instrument holder 21 filled with the vial 502 to the working area Ar2. In the case of reference numeral 19002 in Figure 19, the two empty instrument holders 21 are located adjacent to each other, so the movement distance can be shorter than in the case of reference numeral 19001 in Figure 19. As a result, the time interval between filling one instrument holder 21 with a vial 502 and filling the next instrument holder 21 with a vial 502 can be shortened.

[0138] (Filling Efficiency Improvement Example 2) Reference numeral 19003 in Figure 19 shows an example in which there are multiple adjacent empty instrument holders 21. The vial transport control unit 142 searches for an adjacent empty instrument holder 21 when the vial-side door 27 is opened (i.e., when it becomes possible to load vials 502 into the instrument holders 21). The vial transport control unit 142 determines the transport order of empty instrument holders 21 to the working area Ar2, starting with the section with the largest number of consecutively adjacent empty instrument holders 21. In the example shown by reference numeral 19003 in Figure 19, the vial transport control unit 142 determines the transport order in the following order: section SP3 of three consecutively adjacent empty instrument holders 21, section SP2 of two adjacent empty instrument holders 21, and one empty instrument holder 21 (section SP1). The instrument transport unit 22 transports the sections SP1 to SP3 to the working area Ar2 in this transport order. In this case, vials 502 can be filled in order from the section with the largest number of adjacent empty instrument holders 21. Therefore, in this case too, the above-mentioned time interval can be shortened.

[0139] 20 and 21 are perspective views showing an example of the configuration of the infusion shelf 30. Fig. 21 is a view in which a part of the wall constituting the infusion shelf 30 has been removed. Fig. 22 is a perspective view showing an example of the infusion shelf 30 as viewed from the rear side.

[0140] As shown in Figures 20 and 21, the infusion shelf 30 includes a pusher 31, a first infusion detector 32, a pusher transport unit 35, and a pair of rails 36 (extension units). Also, as shown in Figure 22, the infusion shelf 30 includes a second infusion detector 33 and a shutter 37. As described above, in this embodiment, the infusion shelf 30 includes the infusion shelf 30S and the infusion shelf 30L. The infusion shelves 30S and 30L differ only in size, but have the same internal mechanisms. Furthermore, the components related to the transport of the infusion container 503 in the infusion shelf 30 are controlled by the pusher controller 147.

[0141] Prior to the mixed injection process, the user fills the infusion shelves 30 with infusion containers 503. Similar to the syringe shelves 10 and the vial shelves 20, the plate-like members 301 defining each infusion shelf 30 have a plurality of holes 302 formed therein.

[0142] The pair of rails 36 are provided inside the infusion shelf 30 and extend from the infusion side door 34 (see FIG. 1) toward the rear of the co-infusion device 1 (i.e., in the Y-axis direction). As shown in FIG. 21 , the end of the pair of rails 36 located on the infusion side door 34 side can be referred to as the door-side end 361, and the end located on the rear of the co-infusion device 1 can be referred to as the rear-side end 362. At least one infusion container 503 can be hung from the pair of rails 36. In this embodiment, the neck of the infusion container 503 can be hung between the pair of rails 36. That is, the pair of rails 36 are spaced apart enough to hold the neck of the infusion container 503. By providing the pair of rails 36, when filling the infusion shelf 30 with multiple infusion containers 503, the user simply hangs the multiple infusion containers 503 sequentially from the pair of rails 36. Therefore, the user can easily load multiple infusion containers 503 onto the infusion shelf 30.

[0143] In this embodiment, each infusion shelf 30 is provided with three pairs of rail portions 36. However, the number of pairs of rail portions 36 provided on each infusion shelf 30 is not limited to three. Furthermore, each pair of rail portions 36 may be filled with the same type of infusion container (infusion containers containing the same type of infusion liquid and having the same size). However, each pair of rail portions 36 may also be filled with different types of infusion containers.

[0144] The pushing unit 31 is a member that can move along the pair of rail portions 36 and pushes the infusion container 503 suspended from the pair of rail portions 36 from the door-side end portion 361 to the rear-side end portion 362. In this embodiment, the pushing unit 31 is connected to the pushing transport unit 35. The pushing transport unit 35 is provided along the pair of rail portions 36. The pushing transport unit 35 operates under the control of the pushing control unit 147, thereby moving the pushing unit 31 along the pair of rail portions 36. The pushing transport unit 35 may be, for example, an endless rotating member. The size of the pushing unit 31 and the positional relationship between the pair of rail portions 36 and the pushing transport unit 35 are specified so that the infusion container 503 suspended from the pair of rail portions 36 can be pushed in by the movement of the pushing unit 31.

[0145] When the infusion side door 34 is open, the pushing unit 31 is located at a position PO0 on the door side end 361 side and at a position where it does not interfere with the filling (hanging on the pair of rails 36) of the infusion container 503. For example, when the button 90 (see FIG. 1 ) on the infusion shelf 30 is pressed (when the infusion side door 34 is open), the pushing control unit 147 may control the pushing transport unit 35 to move the pushing unit 31 to the above position.

[0146] When the infusion side door 34 is closed, the pushing unit 31 pushes the infusion container 503 suspended from the pair of rails 36 from the door side end 361 to the rear end 362. In this embodiment, when the infusion side door 34 is closed, the pushing control unit 147 controls the pushing transport unit 35 to move the pushing unit 31 from the position PO0 to the rear end 362. This allows the user to simply load the infusion container 503 into the door side end 361, move the infusion container 503 to the rear end 362, and have the second transport unit 120 remove the infusion container 503. In other words, the second transport unit 120 can efficiently remove the infusion container 503 suspended from the pair of rails 36.

[0147] 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 hanging from the pair of rails 36. After the second transport unit 120 removes the infusion container 503, the pushing unit 31 pushes the remaining infusion containers 503 hanging from the pair of rails 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 toward the rear end 362. As a result, after the infusion container 503 is removed from the pair of rails 36, the remaining infusion containers 503 hanging from the pair of rails 36 can be moved toward the rear end 362. Therefore, the second transport unit 120 can remove the infusion container 503 more efficiently.

[0148] The first infusion detection unit 32 detects infusion containers 503 loaded on the infusion shelf 30. The first infusion detection unit 32 may also detect infusion containers 503 removed from the infusion shelf 30. That is, the first infusion detection unit 32 may function as a count sensor that counts the number of infusion containers 503 loaded on the infusion shelf 30. As shown in Figures 20 and 21 , the first infusion detection unit 32 is provided on the door-side end 361 side of the wall portion that constitutes the infusion shelf 30. The first infusion detection unit 32 is also provided for each pair of rail portions 36. The first infusion detection unit 32 may be, for example, an optical sensor including an emitter and a light receiver, similar to the object detection unit 13 described above.

[0149] In this embodiment, two sensors are provided adjacent to each other in the Y-axis direction as the first infusion detection unit 32. For example, if the sensor on the infusion side door 34 outputs a detection signal and then the sensor behind it outputs a detection signal, the control unit 140 may recognize that an infusion container 503 has been loaded onto the pair of rails 36. For example, if the sensor behind the sensor on the infusion side door 34 outputs a detection signal and then the sensor on the infusion side door 34 outputs a detection signal, the control unit 140 may recognize that an infusion container 503 loaded onto the pair of rails 36 has been removed. This allows the control unit 140 to count the number of infusion containers 503 hanging from the pair of rails 36. Therefore, the control unit 140 can manage the inventory of infusion containers 503 loaded on the infusion shelf 30. Furthermore, for example, if the inventory falls below a predetermined reference inventory number, the touch panel control unit 149 may display an image on the touch panel 80 prompting the user to load an infusion container 503.

[0150] 22 , the second infusion detector 33 is provided at the rear end 362 of the wall portion constituting the infusion shelf 30, and detects an infusion container 503 present at the rear end 362. Similarly to the first infusion detector 32, the second infusion detector 33 is provided for each pair of rail portions 36, and may be an optical sensor having an emitter and a receiver. For example, when the second infusion detector 33 detects an infusion container 503 at the rear end 362, it outputs a detection signal.

[0151] For example, when the pushing control unit 147 receives a detection signal from the second infusion detection unit 33 and then stops receiving the detection signal, the pushing control unit 147 may determine that the infusion container 503 located at the rear end 362 has been removed by the second transport unit 120. Based on this determination, the pushing unit 31 can push the remaining infusion containers 503 hanging from the pair of rails 36 from the door-side end 361 to the rear end 362.

[0152] The shutter 37 prevents the infusion container 503 located at the rear end 362 from moving toward the rear (+Y-axis direction). The shutter 37 is controlled by the control unit 140 to be movable vertically. For example, when the infusion side door 34 is closed, the shutter 37 is controlled by the control unit 140 to be positioned at the rear of the infusion shelf 30 corresponding to the infusion side door 34. This reduces the possibility that the infusion container 503 located at the rear end 362 will fall off the pair of rails 36 when the pushing unit 31 pushes the infusion container 503 hanging from the pair of rails 36 from the door side end 361 to the rear end 362. Furthermore, when the second transport unit 120 removes the infusion container 503, the shutter 37 moves to an infusion shelf 30 other than the one where the infusion container 503 is stored.

[0153] (Processing of the Push-in Control Unit) Fig. 23 is a flowchart showing an example of the processing of the push-in control unit 147. In Fig. 23, the processing of the push-in control unit 147 when the user closes the infusion side door 34 will be described.

[0154] 23, the pushing control unit 147 determines whether the infusion side door 34 is closed (S301). If the pushing control unit 147 determines that the infusion side door 34 is not closed (NO in S301), the pushing control unit 147 continues the processing of S301.

[0155] When the pushing control unit 147 determines that the infusion side door 34 is closed (YES in S301), it controls the pushing transport unit 35 to push the infusion container 503 suspended from the pair of rails 36 from the door side end 361 to the rear end 362 (S302). The pushing control unit 147 controls the pushing transport unit 35 so that the pushing unit 31 pushes the infusion container 503 until the second infusion detection unit 33 detects the infusion container 503. That is, the pushing control unit 147 stops the operation of the pushing transport unit 35 when the second infusion detection unit 33 detects the infusion container 503. This control enables the second transport unit 120 to remove the infusion container 503 suspended from the pair of rails 36 from the rear end 362.

[0156] The pushing control unit 147 determines whether the second transport unit 120 has removed the infusion container 503 from the pair of rails 36 (S303). For example, the pushing control unit 147 determines that the second transport unit 120 has removed the infusion container 503 when the detection signal from the second infusion detection unit 33 is discontinued. When the pushing control unit 147 determines that the second transport unit 120 has not removed the infusion container 503 (NO in S303), it continues the processing of S303.

[0157] When the pushing control unit 147 determines that the second transport unit 120 has removed the infusion container 503 from the pair of rail units 36 (YES in S303), it controls the pushing transport unit 35 to push the remaining infusion containers 503 hanging from the pair of rail units 36 from the door-side end 361 to the back-side end 362. This allows the second transport unit 120 to remove the infusion containers 503.

[0158] In S302, the pushing control unit 147 may control the pushing transport unit 35 in response to a pushing instruction from the user to push the infusion container 503 suspended from the pair of rails 36 from the door-side end 361 to the back-side end 362. The pushing control unit 147 may receive the pushing instruction from the user via the touch panel 80, for example.

[0159] (Modification) The mechanism for transporting the infusion container 503 in the infusion shelf 30 is not limited to the above. For example, the mechanism for transporting the infusion container 503 may be the same as the mechanism for transporting the syringe 501 in the syringe shelf 10.

[0160] That is, the infusion shelf 30 may be provided with multiple instrument holders and instrument transport units instead of the pusher 31, pusher transport unit 35, and pair of rails 36. In this case, the multiple instrument holders are members capable of holding an infusion container 503. The instrument transport unit is a member that transports at least one of the multiple instrument holders to the work area. The work area is an area where the user causes an instrument holder to hold an infusion container 503 and / or where the user removes an infusion container 503 held in an instrument holder. Furthermore, the instrument transport unit may transport another instrument holder in place of the instrument holder located in the work area in response to detection of a user's movement or a user's transport instruction. Note that in this modification, the infusion container 503 is an example of a co-infusion instrument used for co-infusion.

[0161] [Configuration of the printing and inspection unit] Figure 24 is a perspective view showing an example of the overall configuration of the printing and inspection unit 50. Figure 25 is a perspective view of the printing and inspection unit 50 as seen from the rear side. Figure 26 is a perspective view showing an example of the internal configuration of the printing and inspection unit 50. Note that the weighing unit 52 is not shown in Figures 24 and 25. Figure 24 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 unit 120.

[0162] 23 to 25, the printing and inspection unit 50 includes a printing unit 51, a weighing unit 52, a second reading unit 53, an attaching unit 54, a label supply unit 55, and a pair of guide units 56. Each component of the printing and inspection unit 50 is controlled by a printing and inspection unit control unit 148.

[0163] The printing unit 51 prints a type information label LA1 including type information indicating the type of drug mixed by the co-infusion unit 40 with the infusion solution in the infusion container 503. The printing unit 51 may dispense the type information label LA1 on which the type information is printed in the form of a barcode, for example. The printing unit 51 also prints an inappropriateness information label LA2 including inappropriateness information, which will be described later.

[0164] 5, the printing and inspection unit control unit 148 includes an inspection unit 1481. The inspection unit 1481 inspects the infusion container 503 after the medicine is injected.

[0165] In the present embodiment, the inspection unit 1481 determines whether the prescribed amount of drug indicated in the preparation data has been injected into the infusion container 503 after drug injection, based on the weighing result of the weighing unit 52. In other words, the inspection unit 1481 functions as a weight determination unit that determines whether the weight of the infusion container 503 after drug injection is appropriate, based on the weight of the infusion container 503 after drug injection measured by the weighing unit 52 and the prescribed amount. For example, the inspection unit 1481 determines whether the difference between the weight of the infusion container 503 before drug injection and the weight of the infusion container 503 after drug injection matches the prescribed amount of drug indicated in the preparation data.

[0166] The inspection unit 1481 also determines whether an appropriate type information label LA1 is affixed to the infusion container 503 after drug injection based on the reading result of the second reading unit 53. The inspection unit 1481 determines whether the drug indicated by the type information included in the barcode read by the second reading unit 53 is the drug injected into the infusion container 503 whose barcode was read (whether the drug is indicated in the preparation data as the drug to be injected into the infusion container 503).

[0167] If the inspection unit 1481 determines that the inspection result is appropriate, the second transport unit 120 dispenses the infusion container 503 after drug injection to the infusion receiving unit 60. On the other hand, if the inspection unit 1481 determines that the inspection result is inappropriate, the printing unit 51 prints an inappropriate information label LA2 containing inappropriate information. The inappropriate information label LA2 may be printed when the weight measured by the weighing unit 52 is inappropriate. In other words, the inappropriate information may be information indicating that the weight measured by the weighing unit 52 is inappropriate. However, the inappropriate information label LA2 may also be printed when the reading result of the second reading unit 53 is inappropriate. In this case, the inappropriate information may be information indicating that the reading result of the second reading unit 53 is inappropriate.

[0168] The printing unit 51 prints the inadequacy information label LA2, which can be affixed to the infusion container 503 after drug injection. In this embodiment, the inadequacy information label LA2 is affixed by the affixing unit 54, but it may also be affixed by the user, for example. In this case, the affixing unit 54 may not be provided.

[0169] The weighing unit 52 weighs the weight of the infusion container 503 after the drug has been injected. In this embodiment, the weighing unit 52 also weighs the weight of the infusion container 503 before the drug has been injected. In this embodiment, as shown in FIG. 24 , the weighing unit 52 has a pair of locking units 521 that lock the neck of the infusion container 503. The second transport unit 120 locks the neck of the infusion container 503 with the pair of locking units 521, allowing the weighing unit 52 to weigh the infusion container 503. The weighing unit 52 is, for example, a load cell.

[0170] The second reading unit 53 reads the type information label LA1 attached to the infusion container 503 after the medicine has been injected. The second reading unit 53 is, for example, a barcode reader.

[0171] The affixing unit 54 affixes a type information label LA1 to the infusion container 503 after the drug has been injected. For example, the affixing unit 54 affixes the type information label LA1 to the infusion container 503 after the drug has been injected before the inspection by the inspection unit 1481. Thereafter, if the inspection result by the inspection unit 1481 is unsuitable, the affixing unit 54 affixes an inappropriate information label LA2 to the infusion container 503 after the drug has been injected. At this time, the affixing unit 54 may affix the inappropriate information label LA2 to a position that does not overlap with the printing position of the type information included on the type information label LA1. This allows the user to visually recognize the type information even when the inappropriate information label LA2 is affixed.

[0172] In this embodiment, the affixing unit 54 includes a suction mechanism 541 and a movement mechanism 542, as shown in FIG. 25 . The type information label LA1 and the unsuitability information label LA2 printed by the printing unit 51 are dispensed to a position above a tray 511 that is arranged substantially parallel to the XY plane. The suction mechanism 541 adsorbs the type information label LA1 or the unsuitability information label LA2 dispensed onto the tray 511, thereby allowing the affixing unit 54 to hold the type information label LA1 or the unsuitability information label LA2. The movement mechanism 542 can move the suction mechanism 541 from above the tray 511 to the tray 511 or in the opposite direction (i.e., up and down). The movement mechanism 542 can also move the suction mechanism 541 between the tray 511 and an attachment position PO1 (see FIG. 26 ) where the type information label LA1 or the unsuitability information label LA2 is attached to the infusion container 503 after drug injection. In this embodiment, the moving mechanism 542 is configured to be movable in the vertical direction and rotatable in the YZ plane. This allows the affixing unit 54 to affix the type information label LA1 or the inappropriateness information label LA2 held on the tray 511 to the infusion container 503 after drug injection at the affixing position PO1. The suction mechanism 541 releases the suction of the type information label LA1 or the inappropriateness information label LA2 at the affixing position PO1.

[0173] 26 guides the movement of the type information label LA1 or the unsuitability information label LA2 to the infusion container 503 after drug injection when the affixing unit 54 affixes the type information label LA1 or the unsuitability information label LA2 to the infusion container 503 after drug injection. Specifically, the pair of guides 56 are provided to be swingable in the XY plane. Therefore, when the second transport unit 120 presses the infusion container 503 after drug injection against the type information label LA1 or the unsuitability information label LA2 located at the affixing position PO1, the pair of guides 56 swing in the XY plane. Furthermore, the pair of guides 56 are provided with springs 561 at both ends of the pair of guides 56. Therefore, when the second transport unit 120 presses the post-injection infusion container 503 against the type information label LA1 or the inappropriateness information label LA2 located at the affixing position PO1, the pair of guide units 56 oscillate in the YZ plane. The oscillating of the pair of guide units 56 allows the affixing unit 54 to affix the type information label LA1 or the inappropriateness information label LA2 in accordance with the shape of the surface of the post-injection infusion container 503 against which it is pressed. This allows the type information label LA1 or the inappropriateness information label LA2 to be more reliably affixed to the post-injection infusion container 503.

[0174] The label supply unit 55 supplies labels to the printing unit 51. This allows the printing unit 51 to print the type information label LA1 or the unsuitable information label LA2.

[0175] (Processing of the Printing / Inspection Control Unit) Fig. 27 is a flowchart showing an example of processing of the printing / inspection unit control unit 148. As shown in Fig. 27, the second transport control unit 145 controls the second transport unit 120 to transport the infusion container 503 before drug injection from the infusion shelf 30 to the weighing unit 52. When the infusion container 503 before drug injection is locked by the pair of locking units 521, the weighing unit 52 weighs the infusion container 503 before drug injection (S401). The inspection unit 1481 receives the weighing result from the weighing unit 52.

[0176] Next, the second transport control unit 145 controls the second transport unit 120 to transport the measured and pre-medication infusion container 503 to the co-infusion unit 40. The co-infusion unit control unit 144 starts the co-infusion process (S402). Next, the printing and inspection unit control unit 148 controls the printing unit 51 to print a type information label LA1 (S403). That is, the printing unit 51 starts printing the type information label LA1 before the inspection unit 1481 outputs the determination result.

[0177] Conventional co-infusion devices start printing a type information label after determining that the prescribed amount of medication has been injected into the infusion container. On the other hand, the printing and inspection unit 50 starts printing the type information label LA1 without waiting for the determination result from the inspection unit 1481. Therefore, the printing and inspection unit 50 can affix the type information label LA1 to the infusion container 503 after medication injection more quickly than conventional devices.

[0178] When the mixed injection unit control unit 144 completes the mixed injection process (S404), the printing and inspection unit control unit 148 controls the affixing unit 54 to affix the type information label LA1 to the infusion container 503 after drug injection (S405).

[0179] Next, the second transport control unit 145 controls the second transport unit 120 to transport the infusion container 503 after the drug injection to the weighing unit 52, and the weighing unit 52 weighs the infusion container 503 after the drug injection (S406). The inspection unit 1481 receives the weighing result from the weighing unit 52.

[0180] Next, the inspection unit 1481 calculates the difference between the weight of the infusion container 503 before the drug injection and the weight of the infusion container 503 after the mixed injection process (S407).The inspection unit 1481 then determines whether the difference calculated in S407 matches the prescribed amount of drug injected into the infusion container 503 indicated in the preparation data (S408).

[0181] If the inspection unit 1481 determines that the difference calculated in S407 matches the prescribed amount of the drug indicated in the preparation data (YES in S408), it causes the second reading unit 53 to read the barcode on the type information label LA1. Then, the inspection unit 1481 determines whether the type of drug injected in the mixed injection process matches the type of drug prescribed (S409).

[0182] The reading process by the second reading unit 53 may be performed after the type information label LA1 has been affixed to the infusion container 503 after the drug has been injected and before the determination in S409 is performed. In other words, the type information label LA1 may be printed and affixed to the infusion container 503 after the drug has been injected before the reading process by the second reading unit 53 is performed.

[0183] If the inspection unit 1481 determines that the types of the two drugs match (YES in S409), the second transport control unit 145 controls the second transport unit 120 to dispense the infusion container 503 after drug injection to the infusion receiving unit 60 (S410).

[0184] On the other hand, if the inspection unit 1481 determines that the difference calculated in S407 does not match the prescribed amount of the drug indicated in the preparation data (NO in S408), the printing and inspection unit control unit 148 executes the process of S411. Also, if the inspection unit 1481 determines that the type of drug injected in the mixed injection process does not match the type of drug prescribed (NO in S409), the printing and inspection unit control unit 148 executes the process of S411.

[0185] In S411, the printing / inspection unit control unit 148 controls the printing unit 51 to print an unsuitable information label LA2 indicating that the inspection result is unsuitable. The printing / inspection unit control unit 148 controls the affixing unit 54 to affix the printed unsuitable information label LA2 to the post-injection infusion container 503 to which the type information label LA1 has been affixed (S412). In this way, if the inspection result is unsuitable, the type information label LA1 is affixed to the post-injection infusion container 503, and then the unsuitable information label LA2 is affixed. This allows the type information label LA1 to be affixed without waiting for the inspection result. In other words, the co-infusion device 1 can allow the type information label LA1 to be affixed to the post-injection infusion container 503 before the inspection result is output by the inspection unit 1481. In S412, the printing and inspection unit control section 148 may control the pasting section 54 to paste the improperity information label LA2 at a position that does not overlap with the printing position of the barcode on the type information label LA1.

[0186] (Method of affixing type information label and unsuitable information label) Figure 28 is a diagram for explaining a method of affixing a type information label LA1 and an unsuitable information label LA2 to an infusion container 503. Reference numeral 28001 in Figure 28 is a diagram showing a state in which an infusion label including label information is affixed to the body 5031 of the infusion container 503. Reference numeral 28002 in Figure 28 is a diagram showing a state in which the type information label LA1 is affixed to the body 5031 of the infusion container 503. Reference numeral 28003 in Figure 28 is a diagram showing a state in which the type information label LA1 and the unsuitable information label LA2 are affixed to the body 5031 of the infusion container 503.

[0187] As shown by reference numeral 28001 in FIG. 28 , an infusion label is affixed to the body 5031 of the infusion container 503 by the pharmaceutical manufacturer that provides the infusion container 503. The label information includes information about the infusion injected into the infusion container by the pharmaceutical manufacturer (e.g., information indicating the type of infusion). The label information may be in the form of a barcode. Furthermore, the label information may include, for example, information indicating the type of infusion, information indicating the pharmaceutical manufacturer, the composition of the infusion, the amount contained, the expiration date, and the serial number, printed in text or the like on the infusion label.

[0188] 28, the affixing unit 54 may affix the type information label LA1 in the same orientation as the infusion label affixed by the pharmaceutical manufacturer (the orientation in which information related to the infusion is printed). In other words, the affixing unit 54 may affix the type information label LA1 to the infusion container 503 after drug injection so that the top of the type information label LA1 faces the bottom of the infusion container 503 after drug injection.

[0189] For example, after drug injection, the infusion container 503 is used with the bottom of the infusion container 503 facing vertically upward, for example, when administering an intravenous drip. Therefore, by attaching the type information label LA1 as described above, the user can easily read the type information from the type information label LA1 when using the infusion container 503.

[0190] The type information label LA1 is printed with text information such as the patient ID, patient name, ward name, department name, room name, mixed injection date, infusion name, and injected drug name (examples of type information). The type information label LA1 also has printed thereon a barcode BC containing the patient ID and type information. The barcode BC is printed so that, when the type information label LA1 is affixed to the infusion container 503, the longitudinal direction of the barcode BC is substantially parallel to the longitudinal direction of the infusion container 503 (a direction substantially perpendicular to the bottom). This minimizes distortion of the barcode BC due to the curvature of the infusion container 503, thereby improving the accuracy of reading the barcode BC.

[0191] Furthermore, the type information label LA1 does not print the measurement result of the measuring unit 52. This allows the type information label LA1 to be affixed to the infusion container 503 before inspection based on the measurement result of the measuring unit 52. This shortens the inspection time.

[0192] As shown by reference numeral 28003 in Fig. 28 , the affixing unit 54 may affix the unsuitability information label LA2 at a position that does not overlap with the printing position of the type information included in the type information label LA1 so that the user can visually recognize the type information. The unsuitability information label LA2 may be affixed at a position that does not overlap with the printing position of information other than the type information as described above included in the type information label LA1. In this case, the user can easily visually recognize information other than the type information. The unsuitability information may be indicated by, for example, letters or symbols. For example, the unsuitability information may be an X mark.

[0193] Furthermore, by attaching the inappropriateness information label LA2 at a position offset from the type information label LA1, the user can easily peel off the inappropriateness information label LA2. Therefore, for the infusion container 503 after drug injection that has been determined to be inappropriate for the co-infusion device 1 but that the user has determined can be used, the user can easily peel off the inappropriateness information label LA2 and use it.

[0194] [Additional Notes] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention.
