Embodiments for Carrying Out the Invention

[0009] The following describes in detail one embodiment of the present invention. In each drawing, the X-axis and Y-axis are two mutually perpendicular axes in the horizontal plane (the ground surface of the injection device 1). The positive X-axis direction is sometimes referred to as the right direction, and the negative X-axis direction as the left direction. The positive Y-axis direction is sometimes referred to as the back direction, and the negative Y-axis direction as the front direction. The Z-axis is an axis that extends vertically with respect to the XY plane, and the positive Z-axis direction is sometimes referred to as the up direction, and the negative Z-axis direction as the down direction.

[0010] [Overall configuration of the injection device] Figure 1 is a perspective view showing an example of the overall configuration of the injection device 1. As shown in Figure 1, the injection device 1 according to this embodiment includes a syringe rack 10, a vial rack 20, an infusion rack 30, a printing and inspection unit 50, an infusion receiving section 60, a waste bin section 70, a touch panel 80, and buttons 90.

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

[0012] Other examples of the mixing process include drawing a drug from a vial using a syringe and injecting it into another vial, or drawing an infusion from an infusion container using a syringe and injecting it into a vial. If the vial contains a solid drug, the mixing device 1 draws the infusion from the infusion container using a syringe and injects the infusion into the vial. This makes the solid drug in the vial liquid. Subsequently, the mixing device 1 injects the liquid drug into the infusion container using a syringe. Alternatively, the user may directly perform the mixing process using the syringe, vial, and infusion container provided in the mixing device 1.

[0013] The drugs used in the injection process may be, for example, nutritional supplements. The intravenous fluids used in the injection process may be, for example, saline solution (physiological saline) or a liquid containing glucose. The intravenous fluids after drug injection may be, for example, high-calorie intravenous fluids. In other words, the injection device 1 of this embodiment primarily performs injection processing using drugs with a low risk of radiation exposure. For this reason, the injection device 1 has a relatively simple structure, as will be explained below. Specifically, in the injection device 1, for example, the user can fill syringes, vials, and intravenous fluid containers into the device by opening and closing a door. With this configuration, the injection device 1 can perform injection processing more efficiently compared to injection devices that primarily use drugs with a high risk of radiation exposure. However, the air purification unit described later keeps the inside of the injection device 1 clean, reducing the possibility of contamination of drugs and intravenous fluids during injection processing. In addition, to keep the inside of the injection device 1 clean, the inside of the injection device 1 is kept under positive pressure.

[0014] Furthermore, the above preparation data is either preparation data generated based on prescription data or the prescription data itself. Prescription data includes information such as the date of prescription issuance, patient ID, patient name, patient date of birth, drug information (drug code, drug name and dosage, etc.), dosage form information (oral or topical, etc.), usage information (three times a day after each meal, etc.), type of medical treatment (outpatient or inpatient, etc.), medical department, ward, and room. Preparation data also includes information such as patient information, physician information, drug information, prescribed drug quantity, type of drug container, preparation details, preparation procedure information, preparation date, prescription category, administration date, medical department, ward, and preparation time. Examples of drug containers for containing the above drug include ampoules containing drug solution, vials containing drug solution, or vials containing powdered drug. In this embodiment, the case where the drug container is a vial will be used as an example. Examples of preparation details include the type and number of drug containers, syringes, and injection needles used for the injection process. The above preparation procedure information includes the work content, solvent, solvent, amount of solvent, amount of solvent, and amount to be extracted.

[0015] The syringe rack 10 is a storage rack for equipment that can store syringes filled in the injection device 1. The syringe rack 10 is provided with a syringe-side door 16 as an example of an equipment-side door. The user can hold syringes in the syringe rack 10 by opening and closing the syringe-side door 16.

[0016] The vial rack 20 is an equipment storage rack capable of storing vials filled in the injection device 1. The vial rack 20 is provided with a vial-side door 27 as an example of an equipment-side door. The user can hold the vials 502 in the vial rack 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 injection device 1. In this embodiment, the infusion shelf 30 is provided as 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 accommodate infusion containers in either the infusion shelf 30S or 30L according to the size of the infusion containers. In addition, the infusion shelves 30S and 30L are provided with infusion side doors 34S and 34L, respectively. The user can hold the infusion containers in the infusion side doors 34S or 34L by opening and closing the infusion side doors 34S or 34L. Note that the infusion side doors 34S and 34L can be collectively referred to as the infusion side door 34.

[0018] In this embodiment, multiple syringe shelves 10, vial shelves 20, and infusion shelves 30 are provided on the injection device 1. Two syringe shelves 10 are provided in a tiered arrangement in the vertical direction. Three vial shelves 20 are provided in a tiered arrangement in the vertical direction. The syringe shelves 10 are provided on a higher level than the vial shelves 20. The infusion shelves 30 are provided on the opposite side from the syringe shelves 10, with the touch panel 80 located near the center of the front of the injection device 1 when viewed from the front side of the injection device 1. Three infusion shelves 30 are provided in a tiered arrangement in the vertical direction. Infusion shelf 30L is provided below the two infusion shelves 30S.

[0019] The syringe-side door 16, vial-side door 27, and infusion-side doors 34S and 34L are doors that can block user access to the syringe rack 10, vial rack 20, and infusion racks 30S and 30L, respectively. In the injection device 1, the control unit 140 (see Figure 5), described later, controls the device so that only one of the syringe-side door 16, vial-side door 27, and infusion-side doors 34S and 34L is open. As described above, the inside of the injection device 1 is adjusted to be under positive pressure. By keeping only one door open in the injection device 1, the possibility of the inside of the injection device 1 being contaminated by gases from outside the injection device 1 can be reduced.

[0020] Button 90 is a mechanical button that can receive user input to open the syringe-side door 16, the vial-side door 27, and the infusion-side door 34. There is one button 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 button 90. However, if any of the syringe-side door 16, the vial-side door 27, and the infusion-side door 34 are open, the closed doors will remain closed even if user input to button 90 is received. In other words, when the control unit 140 described later opens any of the doors (releases the lock), user input to the button 90 corresponding to the closed door is disabled.

[0021] The control unit 140 may also lock only the doors of the syringe rack 10, vial rack 20, or infusion rack 30 that are accessed by the first transport unit 110 or the second transport unit 120, as described later. Even with this configuration, the possibility of a user touching the first transport unit 110 or the second transport unit 120 while it is in operation can be reduced. In addition, it becomes possible to fill syringes, vials, or infusion containers into the unlocked racks. Therefore, it becomes possible to improve the efficiency of filling. Furthermore, light-emitting members (not shown) may be provided corresponding to each of the syringe rack 10, vial rack 20, and infusion rack 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 it is in operation by lighting up the light-emitting members corresponding to the racks 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 type information labels (described later) and unsuitable information labels (described later) and attaches 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 located below the infusion shelf 30L. Note that the infusion container after drug injection (after mixing) refers to the infusion container in which the drug has been mixed with the infusion solution. On the other hand, the infusion container before drug injection (before mixing) refers to the infusion container before the drug has been mixed with the infusion solution.

[0023] The infusion receiving section 60 is a box for receiving infusion containers after drug injection, to which type information labels and / or unsuitability information labels have been attached. In this embodiment, the infusion receiving section 60 is located below the printing and inspection unit 50. The waste bin section 70 is a box for receiving used syringes. The touch panel 80 has the functions of an operation section that accepts various operations from the user and a display section that displays various information. The operation section and the display section may be provided as separate components. Alternatively, a presentation section (e.g., a speaker) that presents various information may be provided instead of the display section.

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

[0025] [Overview of the internal configuration and operation of the injection device] Figure 2 is a cross-sectional view taken along line II 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 injection device 1 comprises an injection unit 40, a first transport unit 110, a second transport unit 120 (infusion container transport unit), an air purification unit 130, and a pair of inclined units 160. Note that the air purification unit 130 is not shown in Figure 2.

[0026] The injection unit 40 functions as a mixing unit that mixes the drug with the infusion solution in the infusion container. In this embodiment, the injection unit 40 is located opposite the syringe shelf 10 and the vial shelf 20, and is located at the rear center of the injection 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 injection unit 40, and vials from the vial shelf 20 to the injection unit 40. The second transport unit 120 is configured to transport infusion containers from the infusion shelf 30 to the injection unit 40. Through these transports, the injection process can be performed in the injection unit 40.

[0027] The first transport unit 110 grasps the upper part of the body of a syringe stored in the syringe rack 10, moves it to the left, and rotates it 90 degrees on the XY plane to transport it to the injection unit 40. Similarly, the first transport unit 110 grasps the body of a vial stored in the vial rack 20, moves it to the left, and rotates it 90 degrees on the XY plane to transport it to the injection unit 40.

[0028] Furthermore, the first transport unit 110 transports the syringes stored in the syringe rack 10 to the cap attachment / detachment unit 250 (see Figure 11), which will be described later, before transporting them to the injection unit 40. This allows the first transport 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 injection unit 40. The first transport unit 110 also transports the syringes and vials (unnecessary syringes and vials) after the injection process to the waste bin unit 70.

[0029] The second transport unit 120 suctions the body of the infusion containers stored in the infusion rack 30, rotates them 90 degrees on the XY plane, and transports them to the injection unit 40. The second transport unit 120 also suctions the body of the infusion containers after drug injection and transports them to the printing and inspection unit 50, as well as transporting the infusion containers with type information labels (and unsuitable information labels) attached after drug injection to the infusion receiving unit 60.

[0030] The air purification unit 130 purifies the air inside the injection device 1 and exhausts it. In this embodiment, it is located at the top of the injection device 1. The air purified by the air purification unit 130 flows from the top to the bottom of the injection device 1. The air purification unit 130 has, for example, a HEPA (High Efficiency Particulate Air) filter.

[0031] The pair of inclined sections 160 move the infusion container, after drug injection, from the second transport section 120 to the infusion receiving section 60 by the weight of the infusion container itself.

[0032] Figure 4 shows an example of a pair of inclined sections 160. The pair of inclined sections 160 are guide members that guide the infusion container 503, which has been adsorbed by the second transport section 120 after drug injection, to the infusion receiving section 60. As shown in Figure 4, the pair of inclined sections 160 are rod-shaped members that are inclined such that the end on the second transport section 120 side is higher than the end on the infusion receiving section 60. The second transport section 120 operates to lock the neck of the infusion container 503 after drug injection between the pair of inclined sections 160, and then releases its adsorption to the body of the infusion container 503 after drug injection. As a result, the infusion container 503 after drug injection slides along the pair of inclined sections 160 by its own weight and is dispensed into the infusion receiving section 60. In other words, with a simple configuration of a pair of inclined sections 160, the infusion container 503 after drug injection can be dispensed into the infusion receiving section 60 by its own weight.

[0033] The arrangement of each component in the injection device 1 is not limited to the arrangement described above. For example, the vial shelf 20 may be placed on the upper level of the syringe shelf 10. Also, the positions of the syringe shelf 10 and vial shelf 20 and the infusion shelf 30 may be reversed. Furthermore, the syringe shelf 10, vial shelf 20 and infusion shelf 30 may be placed together on either the left or right side of the injection device 1, and the injection unit 40 may be placed in a different position from the syringe shelf 10, vial shelf 20 and infusion shelf 30. Also, the syringe shelf 10, vial shelf 20 and infusion shelf 30 may not each have multiple levels, but rather each may have only one level. Furthermore, the positions of the printing / inspection unit 50 and the infusion receiving unit 60 may be reversed. The arrangement of each component in the injection device 1 should be determined considering user convenience and ease of manufacturing.

[0034] Furthermore, a syringe-side door 16 and / or a vial-side door 27 may be provided on the side of the injection device 1. As will be described later, one syringe and one vial are filled from the front of the injection device 1. On the other hand, multiple syringes or multiple vials can be filled from the side of the injection device 1. Therefore, by providing a syringe-side door 16 and / or a vial-side door 27 on the side of the injection device 1, the user can be more efficiently allowed to fill syringes and vials. If 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 injection device 1. In this case as well, the user can be more efficiently allowed to fill infusion containers.

[0035] [Other components] Figure 5 is a block diagram showing an example of the overall configuration of the injection device 1. As shown in Figure 5, it comprises a control unit 140 and a storage unit 200. Note that Figure 5 only illustrates the main hardware configuration of the injection device 1 that can be controlled by the control unit 140.

[0036] The control unit 140 comprehensively controls the injection device 1. The control unit 140 includes, for example, a syringe transport control unit 141, a vial transport control unit 142, a first transport control unit 143, an injection unit control unit 144, a second transport control unit 145, a push 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 a description of each component. The storage unit 200 stores various programs and data used by the control unit 140. The specific configuration of the injection device 1 will be described below, with reference to Figure 5 as appropriate.

[0037] [Composition of the injection unit] Figure 6 shows an example of the configuration of the injection unit 40. As shown in Figure 6, the injection unit 40 comprises a syringe holder 41, a vial holder 42, and an infusion container holder 43. The operation of each component of the injection unit 40 is controlled by the injection unit control unit 144 shown in Figure 5.

[0038] The syringe holder 41 is a member that holds the syringe 501. The syringe 501 consists 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. By moving the plunger 5015 in and out of the syringe 5011, drugs or other substances can be drawn into the syringe 5011, or drugs or other substances inside the syringe 5011 can be discharged. The syringe 5011 also includes a needle-side end 5012 to which the needle 5014 is attached, and a flange 5013 at the end opposite to the needle-side end 5012, which is the end on which the plunger 5015 moves in and out. The vial holder 42 is a member that holds the vial 502. The infusion container holder 43 is a member that holds the infusion container 503. In this embodiment, the syringe holder 41 holds the lower part of the body (syringe 5011) of the syringe 501. The syringe holder 41 also holds the syringe at the needle end 5012 and the flange 5013. The vial holder 42 and the infusion container holder 43 hold the necks of the vial 502 and the infusion container 503, respectively.

[0039] The syringe holder 41 comprises a pair of needle gripping parts 411, a syringe gripping part 412, a base 415 (see Figure 7), and a pair of first syringe holder parts 416. The base 415 is a member to which a pair of second syringe holder parts 413 (described later) and a pair of needle gripping parts 411 are provided. The base 415 is also provided so as to be movable in the vertical direction by the injection unit control unit 144.

[0040] The pair of needle-holding portions 411 are members that hold the needle 5014. The pair of needle-holding portions 411 hold the needle 5014 and position the tip of the needle 5014 at a fixed position. This allows even a bent needle 5014 to be punctured at the desired position (correct position) of the stopper provided on the infusion container 503 during the injection process. In this embodiment, the pair of needle-holding portions 411 also function as electrodes. By making the pair of needle-holding portions 411 function as electrodes, the injection unit control unit 144 can detect when liquid (e.g., drug or infusion) is attached to either of the needle-holding portions 411. Specifically, when liquid is attached to either of the two needle-holding portions or one of the needle-holding portions constituting the pair of needle-holding portions 411, bringing the two needle-holding portions close to each other causes electrical conductivity between the pair of needle-holding portions 411 via the liquid. The injection unit control unit 144 can detect when liquid is adhering to the pair of needle clamping parts 411 by detecting this conductivity.

[0041] If liquid is present on the needle 5014, that liquid will adhere to the pair of needle gripping parts 411. Therefore, when the pair of needle gripping parts 411 subsequently hold the needle 5014 of another syringe 501, the liquid will adhere to that needle 5014. In other words, contamination occurs in this case.

[0042] As shown in Figure 5, the injection unit control unit 144 includes a liquid detection unit 1441. The liquid detection unit 1441 detects whether or not liquid is adhering to the pair of needle gripping parts 411. Specifically, with the needle 5014 positioned between the two needle gripping parts constituting the pair of needle gripping parts 411, the injection unit control unit 144 brings the two needle gripping parts closer together to a position just before gripping the needle 5014 (a position slightly separated from the needle 5014). In this state, the liquid detection unit 1441 can detect whether or not liquid is adhering to the pair of needle gripping parts 411 by determining whether or not to detect conductivity in the pair of needle gripping parts 411. If liquid is adhering to the pair of needle gripping parts 411, the pair of needle gripping parts 411 will be electrically connected through the liquid. As a result, the liquid detection unit 1441 can detect that liquid is adhering to the pair of needle gripping parts 411. Furthermore, if the touch panel control unit 149 detects that liquid is adhering to the pair of needle gripping parts 411, it may display an image on the touch panel 80 indicating that liquid is adhering to the pair of needle gripping parts 411. In this case, the user can be prompted to clean the pair of needle gripping parts 411. This reduces the possibility of the aforementioned contamination occurring.

[0043] Furthermore, the injection unit control unit 144 may bring the two needle gripping parts closer to the position immediately before the first transport unit 110 holds the syringe 501 in the syringe holding unit 41 (i.e., before positioning the needle 5014 between the two needle gripping parts). Even in this case, if liquid is attached to the pair of needle gripping parts 411, the pair of needle gripping parts 411 will be electrically connected through the liquid. Therefore, the liquid detection unit 1441 can detect that liquid is attached to the pair of needle gripping parts 411.

[0044] The pair of needle-holding portions 411 is an example of a needle-holding portion that holds the needle 5014. That is, the syringe-holding portion 41 does not necessarily need to have a pair of needle-holding portions 411, but only needs to have a member that holds the needle 5014. In this case, in addition to the pair of needle-holding portions 411, a pair of electrodes that conduct electricity when liquid is attached to the pair of needle-holding portions 411 may be provided. Note that in this specification, when referring to a "pair of members," the pair of members does not necessarily have to be a "one pair" as long as they can perform the function of the members.

[0045] The pair of first syringe holders 416 are the members that initially hold the syringe 501 transported by the first transport unit 110 from the syringe rack 10. The pair of first syringe holders 416 grip the sides of the syringe 5011 (e.g., the lower part of the syringe 5011) inserted into the pair of first syringe holders 416 from the left and right directions.

[0046] The syringe clamping portion 412 is a member that clamps the syringe 501 along the extension direction of the syringe 501 at the needle-side end 5012 and the flange 5013. Specifically, the syringe clamping portion 412 comprises 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 is an example of a syringe holding portion that holds the needle-side end 5012.

[0047] In this embodiment, when the syringe 501 is held by the syringe clamping portion 412, a pair of second syringe holding portions 413 contact the needle end portion 5012 from below, and a pair of third syringe holding portions 414 contact the flange 5013 from above. As a result, the syringe clamping portion 412 can clamp the syringe 501 along the extension direction of the syringe 501.

[0048] For example, when the syringe 5011 is held only by its sides by a pair of first syringe holders 416, a certain amount of clamping force is required to secure the syringe 5011 so that it does not slip in the extension direction of the syringe 501. Therefore, the force applied to secure the syringe 5011 may cause it to deform. By clamping along the extension direction of the syringe 501, the syringe clamping portion 412 can secure the syringe 5011 so that it does not slip in the extension direction of the syringe 501 with less force than when clamping only the sides of the syringe 5011. Thus, the possibility of deformation of the syringe 5011 can be reduced.

[0049] The pair of second syringe holders 413 have a mortar-like shape into which the needle-side end 5012 can be fitted (see Figure 7). The cross-sectional shape of the needle-side end 5012 is triangular with the needle-attaching side as the apex, or trapezoidal with the needle-attaching side shorter than the side of the syringe 5011 on the body side. Therefore, in the cross-sectional shape of the pair of second syringe holders 413, the portion inserted into the needle-side end 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, allowing the pair of second syringe holders 413 to fit the needle-side end 5012. Thus, when the syringe clamping portion 412 clamps the syringe 501, the entire needle 5014 can protrude from the pair of second syringe holders 413. However, the pair of second syringe holders 413 are not limited to the above shape, as long as the needle-side end 5012 can be fitted into them.

[0050] (Operation of the syringe holder) Figure 7 illustrates an example of the operation when the syringe 501 is held by the syringe holder 41. Reference numeral 7001 in Figure 7 indicates the state in which a pair of first syringe holders 416 hold the syringe 501. Reference numeral 7002 in Figure 7 indicates the state in which a pair of second syringe holders 413 hold the needle end 5012. Reference numeral 7003 in Figure 7 indicates the state in which a pair of third syringe holders 414 hold the flange 5013. Reference numeral 7004 in Figure 7 indicates the state in which a pair of needle clamping parts 411 clamp the needle 5014.

[0051] As shown by reference numeral 7001 in Figure 7, the first transport unit 110 causes the syringe 501 transported from the syringe rack 10 to be held in a pair of first syringe holding units 416. In this state, the needle end 5012 is not fitted into the pair of second syringe holding units 413. Next, as shown by reference numeral 7002 in Figure 7, the injection unit control unit 144 moves the base 415 upward. This causes the needle end 5012 to fit into the pair of second syringe holding units 413.

[0052] With the needle end 5012 fitted into the pair of second syringe holding parts 413, the injection unit control unit 144 moves the base 415 further upward. As a result, as shown by reference numeral 7003 in Figure 7, the pair of third syringe holding parts 414 come into contact with the flange 5013 (the overhang of the syringe 5011). In this state, the syringe clamping part 412 clamps the syringe 501 between the needle end 5012 and the flange 5013 along the extension direction of the syringe 501.

[0053] The injection unit control unit 144 may also detect the force applied to the syringe 501 in the stretching direction. When the force applied to the syringe 501 in the stretching direction exceeds a predetermined value, the injection unit control unit 144 can determine that the pair of third syringe holders 414 are in contact with the flange 5013 with the needle end 5012 fitted into the pair of second syringe holders 413. The above predetermined value may be determined in advance through experiments or other means.

[0054] If the injection unit control unit 144 determines that the force exceeds a predetermined value, it stops the upward movement of the base 415. Then, as shown by reference numeral 7004 in Figure 7, the injection unit control unit 144 moves the pair of needle clamping parts 411 toward the needle 5014, thereby causing the needle 5014 to be clamped by the pair of needle clamping parts 411.

[0055] (Detection process for the contamination status of the pair of needle gripping parts) Figure 8 is a flowchart illustrating an example of the process for detecting the contamination status of a pair of needle-holding parts 411. As shown in Figure 8, the injection unit control unit 144 determines that the needle-side ends 5012 are fitted into the pair of second syringe-holding parts 413, and that the pair of third syringe-holding parts 414 are in contact with the flange 5013. In this case, the injection unit control unit 144 brings the two needle-holding parts constituting the pair of needle-holding parts 411 closer to the position immediately before the above (S1). Next, the liquid detection unit 1441 determines whether the pair of needle-holding parts 411 have become electrically conductive (S2). If the liquid detection unit 1441 determines that the pair of needle-holding parts 411 have become electrically conductive (YES in S1), the touch panel control unit 149 displays an image on the touch panel 80 prompting the user to clean the pair of needle-holding parts 411 (S3). This allows the user to be prompted to clean the pair of needle-holding parts 411, thereby reducing the possibility of contamination. 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 injection unit control unit 144 may bring the two needle gripping parts closer to the position immediately before the first transport unit 110 holds the syringe 501 in the syringe holding unit 41. In this case, if NO is selected in S2, the first transport unit 110 may hold the syringe 501 in the syringe holding unit 41 and then grip the needles with the pair of needle gripping parts 411.

[0057] [Configuration of the first and second transport units] (Configuration of the first transport unit) Figure 9 shows an example of the configuration of the first transport unit 110. As shown in Figure 9, the first transport unit 110 comprises a first claw portion 111, a second claw portion 112, and a rotating shaft portion 113. The operation of each component of the first transport unit 110 is controlled by the first transport control unit 143. The movement of the first transport unit 110 between the syringe rack 10 or vial rack 20 and the injection unit 40 is also controlled by the first transport control unit 143.

[0058] The first claw portion 111 and the second claw portion 112 are members that grip the upper part of the syringe 5011 of the syringe 501 or the neck of the vial 502, respectively. The first claw portion 111 and the second claw portion 112 only need to have a structure that can hold the syringe 501 and the vial 502, respectively. However, in this embodiment, the injection unit 40 holds the lower part and both ends of the syringe 5011 of the syringe 501, and the body of the vial 502. Therefore, in this embodiment, the first transport unit 110 is configured to grip the upper part of the syringe 5011 of the syringe 501 or the neck of the vial 502. This makes it possible to make the position in which the injection unit 40 grips the syringe 501 or vial 502 from both radial sides different from the position in which the first transport unit 110 grips the syringe 501 or vial 502 from both radial sides. Therefore, even when the first transport unit 110 is brought close to the first syringe holding unit 416, the first transport unit 110 and the first syringe holding unit 416 do not come into contact with each other. As a result, the first transport unit 110 can bring the syringe 501 or vial 502 close to the injection unit 40, or close to the syringe 501 or vial 502 held in the injection unit 40. Thus, the transfer of the syringe 501 or vial 502 to and from the injection unit 40 can be performed efficiently. In addition, 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 transport unit 110 is equipped with a first claw portion 111 and a second claw portion 112, which enables efficient execution of the injection process. For example, during the injection process, the first transport control unit 143 holds a syringe 501 or vial 502 to be used for the next injection process with the first claw portion 111 in order to transport it to the injection unit 40. After that, the first transport control unit 143 holds the syringe 501 or vial 502 with the second claw portion 112 in order to receive it from the injection unit 40 after the injection process is completed and transport it to the waste bin portion 70. Then, with the first claw portion 111 holding the syringe 501 or vial 502, the first transport control unit 143 transports the first transport unit 110 to the injection unit 40. Therefore, the time required to transport the syringe 501 or vial 502 to the waste bin section 70, and then to the syringe 501 or vial 502 to be used for the next injection process, by holding it in the first transport section 110 and transporting it to the injection unit 40, can be shortened.

[0060] The first transport unit 110 is a transport unit shared by both the syringe 501 and the vial 502, but it is not limited to this. A dedicated transport unit for transporting the syringe 501 and a dedicated transport unit for transporting the vial 502 may also be provided.

[0061] (Configuration of the second transport unit) Figure 10 shows an example of the configuration of the second transport unit 120. As shown in Figure 10, the second transport unit 120 includes a suction unit 121 and a third reading unit 122. The operation of each component of the second transport unit 120 is controlled by the second transport control unit 145. The movement of the second transport unit 120 between the mixing unit 40 and the printing and inspection unit 50 is also controlled by the second transport control unit 145.

[0062] The adsorption part 121 is configured to adsorb the body portion 5031 of the infusion container 503. The second transport part 120 only needs to be configured to hold the infusion container 503. However, in this embodiment, the injection unit 40 holds the neck portion of the infusion container 503. Therefore, in this embodiment, the second transport part 120 is configured to hold the body portion 5031 of the infusion container 503. This makes it possible to make the holding position of the infusion container 503 when the injection unit 40 holds it different from the holding position of the infusion container 503 when the second transport part 120 holds it. Therefore, even if the adsorption part 121 (infusion holding mechanism) of the second transport part 120 is brought close to the infusion container holding part 43 (infusion holding mechanism) of the injection unit 40, the infusion container holding part 43 and the adsorption 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 injection unit 40, or closer to the infusion container 503 held in the injection unit 40. Thus, the transfer of the infusion container 503 to and from the injection unit 40 can be performed efficiently.

[0063] The third reading unit 122 reads the label information contained in the infusion label affixed 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 the barcode, the third reading unit 122 may be implemented by a barcode reader.

[0064] [Structure of the cap attachment / detachment part] Figure 11 shows an example of the configuration of the cap attachment / detachment section 250. The cap attachment / detachment section 250 is used to attach and detach the needle cap 5016 of the syringe 501. The syringe 501 that is filled into the syringe rack 10 has the needle cap 5016 attached to the needle 5014.

[0065] As shown in Figure 11, in this embodiment, the cap attachment / detachment section 250 comprises a cap insertion section 251, a pair of cap clamping sections 252, and a solenoid 253. The cap insertion section 251 is into which the needle cap 5016 attached to the needle 5014 of the syringe 501 is inserted, and a spring (not shown) presses the inserted needle cap 5016 toward the syringe 5011. The pair of cap clamping sections 252 are the parts that 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 sections 252. The cap insertion section 251 is provided with a spring (not shown), and the solenoid 253 turns on when the spring is compressed to a predetermined length or less. As a result, the solenoid 253 closes the pair of cap clamping sections 252. On the other hand, the solenoid 253 is turned off by the cap attachment / detachment control unit 150, which opens the pair of cap clamping parts 252.

[0066] Figure 12 shows the process of the cap attachment / detachment unit 250 removing the needle cap 5016 from the syringe 501. As shown by reference numeral 12001 in Figure 12, the first transport unit 110 transports the syringe 501 taken from the syringe rack 10 to the cap attachment / detachment unit 250. Then, as shown by reference numeral 12002 in Figure 12, the first transport unit 110 inserts the needle cap 5016 of the syringe 501 into the cap attachment / detachment 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 turns on, and the pair of cap clamping parts 252 close. As a result, the cap attachment / detachment unit 250 holds the needle cap 5016. Subsequently, as shown by reference numeral 12003 in Figure 12, the first transport unit 110 moves away from the cap attachment / detachment unit 250. As a result, the needle cap 5016 is removed from the syringe 501. Therefore, the first transport unit 110 can transport the syringe 501, from which the needle cap 5016 has been removed, to the injection unit 40.

[0067] If the needle cap 5016 is simply clamped and removed from the needle 5014, there is a risk that the needle 5014 will move with the needle cap 5016 and be removed from the syringe 5011. As described above, after pushing the needle cap 5016 into the cap attachment / detachment part 250, the cap attachment / detachment part 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, which is inside the needle cap 5016, towards the syringe 5011, and the needle 5014 fits more firmly into the syringe 5011 than the needle cap 5016. Therefore, when the needle cap 5016 is removed from the needle 5014, the needle 5014 will not be removed from the syringe 5011.

[0068] In this configuration, the needle cap 5016 is pushed into the cap attachment / detachment section 250 by the first transport unit 110 moving relative to the cap attachment / detachment section 250, but this is not limited to this configuration. For example, the first transport unit 110 may stop immediately before or after inserting the needle cap 5016 into the cap attachment / detachment section 250, and then the cap attachment / detachment section 250 may move toward the first transport unit 110, thereby pushing the needle cap 5016 into the cap attachment / detachment section 250.

[0069] Furthermore, the first transport unit 110 transports the syringe 501 after the injection process to the cap attachment / detachment unit 250, inserts the needle 5014 of the syringe 501 into the needle cap 5016 held by the cap attachment / detachment unit 250, and fits the needle 5014 onto the needle cap 5016. In this state, the cap attachment / detachment control unit 150 turns off the solenoid 253, causing the pair of cap clamping parts 252 to open. Subsequently, the first transport unit 110 moves away from the cap attachment / detachment unit 250. This allows the needle cap 5016 to be attached to the syringe 501 after the injection process. Therefore, the first transport unit 110 can dispose of the syringe 501 with the needle cap 5016 attached to the waste bin unit 70.

[0070] [Configuration of syringe rack] The detailed configuration of the syringe rack 10 will be described below based on Figures 13 to 16. Figure 13 is a perspective view showing an example of the overall configuration of the syringe rack 10 and the vial rack 20. Figure 14 is a perspective view showing an example of the configuration of one syringe rack 10 and one vial rack 20. Figure 15 is a perspective view showing an example of the configuration of one syringe rack 10 and one vial rack 20 when viewed from a different direction than Figure 14. Figure 16 is a diagram showing an example of the configuration of one syringe rack 10 and one vial rack 20 when viewed from the first transport unit 110 side.

[0071] As shown in Figures 13 to 15, the syringe rack 10 comprises a plurality of equipment holding units 11, an equipment transport unit 12, an object detection unit 13, a syringe detection unit 14, a needle detection unit 15, and a syringe detection unit 17. In the syringe rack 10, the components related to the transport of syringes 501 are controlled by the syringe transport control unit 141. Although an equipment holding unit 11 is also attached to the mounting part 1211 of the equipment transport unit 12 shown in Figure 13, it is not shown in the figure.

[0072] Prior to the injection process, syringes 501 are filled into the syringe rack 10 by the user. The syringes 501 are filled into the syringe rack 10 with the needle caps 5016 attached to the needles 5014.

[0073] In this embodiment, as shown in Figures 13 and 14, a plurality of holes 172 are formed in the plate-shaped member 171 that defines each syringe shelf 10. This allows, for example, the air purified by the air purification unit 130 (see Figure 3) to flow efficiently from the top to the bottom of the injection device 1. As a result, the entire space inside the injection device 1 can be kept clean.

[0074] Multiple instrument holding parts 11 are members capable of holding syringes 501. In this embodiment, one syringe 501 is held in one instrument holding part 11, but multiple syringes 501 may be held in one instrument holding part 11. 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. As a result, the instrument holding part 11 holds the neck of the syringe 501. In this embodiment, the pair of instrument clamping parts 1112 are provided on the upper part of the syringe shelf 10. As a result, the syringe 501 is held in the instrument holding part 11 with the needle cap 5016 (needle 5014) positioned downwards. The pair of instrument clamping parts 1112 are provided at a height such that the syringe 501 does not touch the plate-shaped member 171 when the syringe 501 is held in the instrument holding part 11.

[0076] In this embodiment, in the injection unit 40, the syringe 501 is positioned so that the needle 5014 is facing downwards. Therefore, the pair of equipment clamping parts 1112 are provided at the top of the syringe shelf 10. The cap attachment / detachment part 250 (see Figure 11) is also positioned at the bottom of the injection device 1 so that the cap insertion part 251 faces upwards, taking this into consideration. However, for example, if the syringe 501 is positioned in the injection unit 40 so that the needle 5014 is facing upwards, the pair of equipment clamping parts 1112 may be provided at the bottom of the syringe shelf 10. Also, the cap attachment / detachment part 250 may be positioned at the top of the injection device 1 so that the cap insertion part 251 faces downwards.

[0077] The pair of instrument clamping portions 1112 are biased toward each other so that they can clamp the syringe 501. In this embodiment, when the pair of instrument clamping portions 1112 are not clamping the flange 5013, they are spaced apart to a degree smaller than the width of the flange 5013. When the flange 5013 is inserted between the pair of instrument clamping portions 1112, the pair of instrument clamping portions 1112 move to conform to the shape of the flange 5013. As a result, the pair of instrument clamping portions 1112 can clamp the syringe 501.

[0078] Below the tips of the pair of instrument clamping portions 1112, there is a pair of free rollers 1111 that have a rotation axis extending in the vertical direction and are rotatable in the XY plane. The pair of free rollers 1111 hold the vicinity of the flange 5013 of the syringe 5011, which is clamped by the pair of instrument clamping portions 1112.

[0079] The equipment transport unit 12 is a component that transports at least one of the multiple equipment holding units 11 to the work area Ar1. In this embodiment, the equipment transport unit 12 is an endless rotating member to which multiple equipment holding units 11 are connected. Therefore, in this embodiment, the equipment transport unit 12 transports the equipment holding units 11 one by one to the work area Ar1. However, the equipment transport unit 12 may be a transport unit that transports multiple equipment holding units 11 to the work area Ar1 at once.

[0080] Here, the work area Ar1 is the area where the user holds the syringe 501 in at least one of the multiple equipment holding parts 11, and where the user removes the syringe 501 held in at least one of the multiple equipment holding parts 11. In other words, the work area Ar1 functions as both a filling area where the syringe 501 can be filled and a collection area where the syringe 501 can be retrieved. In this embodiment, the work area Ar1 is the area where the user holds the syringe 501 in one of the equipment holding parts 11, and where the user removes the syringe 501 held in one of the equipment holding parts 11. Also in this embodiment, the work area Ar1 is located on the syringe-side door 16 side shown in Figure 1. This allows the user to fill the equipment holding part 11 with the syringe 501 and remove the syringe 501 held in the equipment holding part 11 from the syringe-side door 16 side. Furthermore, the syringe-side door 16 functions as a door capable of blocking user access to the work area Ar1.

[0081] Furthermore, the work area Ar1 may function only as an area where the user holds the syringe 501 in at least one of the multiple equipment holding parts 11. In this case, the area where the user removes the syringe 501 held in the equipment holding part 11 may be located separately from the work area Ar1.

[0082] In this embodiment, the equipment transport unit 12, triggered by the detection of user movement, transports a different equipment holding unit 11 in place of the equipment holding unit 11 located in the work area Ar1. The equipment transport unit 12 changes the equipment holding unit 11 located in the work area Ar1 by, for example, rotating counterclockwise. This transport operation allows a different equipment holding unit 11, which does not hold the syringe 501, to be transported to the work area Ar1 in place of the equipment holding unit 11 that holds the syringe 501. Therefore, the user only needs to have the syringe 501 held by the equipment holding unit 11 transported to the work area Ar1. Consequently, the effort required of the user in the syringe 501 filling operation can be reduced.

[0083] Specifically, the equipment transport unit 12 transports another equipment holder 11 to the work area Ar1 after the object detection unit 13 has detected an object (e.g., the user's hand) and then detected user action, such as the object no longer being detected. In this case, the equipment transport unit 12 transports another equipment holder 11 to the work area Ar1 when the user's hand is inserted into the work area Ar1, the user holds the syringe 501 in the equipment holder 11, and then the user's hand leaves the work area Ar1. Therefore, the equipment transport unit 12 can transport another equipment holder 11 to the work area Ar1 without the user giving a transport instruction to the injection device 1. Consequently, the effort required of the user in filling the syringe 501 can be further reduced. Furthermore, the equipment transport unit 12 does not transport another equipment holder 11 to the work area Ar1 until the user's hand leaves the work area Ar1, i.e., while the user's hand is in the work area Ar1. Therefore, the safety of the user in filling the syringe 501 can be ensured.

[0084] In this embodiment, in addition to detecting user movements, the equipment transport unit 12 transports another equipment holder 11 to the work area Ar1 when the syringe detection unit 14 detects a syringe 501 held in the equipment holder 11. Therefore, the equipment transport unit 12 can transport another equipment holder 11 to the work area Ar1 after the user has placed the syringe 501 in the equipment holder 11 located in the work area Ar1. Consequently, the possibility of the equipment transport unit 12 transporting another equipment holder 11 to the work area Ar1 without the syringe 501 being held in the equipment holder 11 is reduced.

[0085] The object detection unit 13 is a component that detects an object inserted into the work area Ar1. In this embodiment, the object detection unit 13 detects the user's hand or arm when it is inserted into the work area Ar1. The object detection unit 13 uses the side of the syringe rack 10 where the syringe side door 16 shown in Figure 1 is located (the front side of the injection device 1) as viewed from the equipment transport unit 12 as the object detection area. Specifically, the object detection unit 13 is provided at a position on the wall portion constituting the syringe rack 10 corresponding to the area between the syringe side door 16 and the equipment holding unit 11 located in the work area Ar1. In this embodiment, in order to improve the accuracy of object detection in the work area Ar1, a plurality of object detection units 13 are provided along the vertical direction of the syringe rack 10. The object detection unit 13 may be, for example, an optical sensor composed of an emitting unit that emits light and a light receiving unit provided at a position opposite the emitting unit that receives light from the emitting 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 can be any type of sensor as long as it is capable of detecting an object inserted into the work area Ar1. The same 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 detecting the object.

[0086] The syringe detection unit 14 is a component that detects a syringe 501 held in the equipment holding unit 11 located in the work area Ar1. In other words, the syringe detection unit 14 functions as an equipment detection unit that detects a syringe held in the equipment holding unit 11 located in the work area Ar1. In this embodiment, the syringe detection unit 14 detects a syringe 5011 when a syringe 501 is held in the equipment holding unit 11. As shown in Figures 13 and 14, the syringe detection unit 14 is provided on the wall portion constituting the syringe rack 10, at a position facing the equipment 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 from the object. When the syringe detection unit 14 detects a syringe 5011, for example, 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 equipment holding unit 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 Figures 13 and 14, the needle detection unit 15 is provided on the wall portion of the syringe rack 10, at a position opposite the equipment holding unit 11 located in the work area Ar1. In this embodiment, the needle detection unit 15 is arranged in the same row as the syringe detection unit 14 in the vertical direction, but it is not necessarily required that they be in the same row. 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 a syringe detection unit. In this case, the syringe detection unit 14 may not be provided. When the needle detection unit 15 detects, for example, 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 portion in the same row along 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 equipment holding unit 11 based on whether or not the needle cap 5016 is detected in each of the multiple needle detection units 15. Therefore, the control unit 140 can determine whether or not the needle 5014 is suitable to be attached to the syringe 501 held in the equipment holding unit 11. If the control unit 140 determines that the needle 5014 is unsuitable to be attached 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 is detected and the length of the needle 5014, and information indicating the thickness (diameter) of the syringe 501 and the length of the needle 5014 may be stored in the storage unit 200. Furthermore, multiple needle detection units for detecting the length of the needle 5014 may be provided separately from the needle detection unit 15.

[0089] The syringe detection unit 17 is a component capable of detecting the diameter of the syringe 5011. The syringe detection unit 17 is provided in a position on the wall of the syringe rack 10 where it can detect the syringe 5011 being transported by the equipment transport unit 12. The syringe detection unit 17 may be provided such that, for example, 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. The syringe detection unit 17 may also function as a syringe detection unit. In this case, the syringe detection unit 14 may not be provided.

[0090] The syringe detection unit 17, for example, when it detects a syringe 5011, 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 equipment transport unit 12 in front of the syringe detection unit 17, and information indicating the diameter of various syringes 5011 that can be used in the injection device 1. After calculating the detection time of the syringe 5011 by the syringe detection unit 17, the control unit 140 calculates the diameter of the syringe 5011 that passed in front of the syringe detection unit 17 by multiplying the detection time by the speed of the equipment transport unit 12. This allows the control unit 140 to identify the diameter of the syringe 5011 (i.e., the type of syringe 501) that passed in front of the syringe detection unit 17. Therefore, the control unit 140 can determine, for example, whether the syringe 501 held in the equipment holding unit 11 is suitable as the syringe 501 to be used to draw up the drug indicated in the preparation data (the syringe 501 to be filled into the syringe shelf 10). If the control unit 140 determines that the syringe 501 held in the equipment holding unit 11 is unsuitable as the syringe 501 to be used to draw up the drug, the touch panel control unit 149 may display an image indicating this unsuitability on the touch panel 80. Information indicating the type of syringe 501 to be used to draw up the drug indicated in the preparation data may be stored in the storage unit 200 together with the preparation data.

[0091] Alternatively, for example, the memory unit 200 may store, in association with information identifying each equipment holding unit 11, information indicating the type of syringe 501 held in each equipment holding unit 11, and information indicating the transport position of each equipment 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 take out from the equipment holding unit 11. Therefore, the first transport unit 110 can transport the appropriate syringe 501 to the injection unit 40.

[0092] (Process to initiate transport of the equipment holding unit) Figure 18 is a flowchart showing an example of the process when transporting the equipment holding unit 11 is started. Reference numeral 18001 in Figure 18 is a flowchart showing an example of the process when the syringe transport control unit 141 starts transporting the equipment holding unit 11.

[0093] As shown by reference numeral 18001 in Figure 18, the syringe transport control unit 141 determines whether or not the object detection unit 13 has detected the user's hand inserted into the work area Ar1 (S101). When the syringe transport control unit 141 receives a detection signal from the object detection unit 13, it determines that it has detected the user's hand. If the syringe transport control unit 141 determines that it has not detected the user's hand (NO in S101), it continues the process in S101.

[0094] If the syringe transport control unit 141 determines that it has detected the user's hand (YES in S101), it determines whether or not 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] If 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] If the syringe transport control unit 141 determines that the needle 5014 has been detected (YES in S103), it determines whether or not the user's hand inserted into the work area Ar1 has been detected (S104). For example, the syringe transport control unit 141 determines that the user's hand has been detected when the reception of the detection signal that it had been continuously receiving from the object detection unit 13 in S101 is interrupted. If the syringe transport control unit 141 determines that the user's hand has not been detected (NO in S104), it returns to the process in S102.

[0097] If the syringe transport control unit 141 determines that the user's hand is no longer detected (YES in S104), it controls the equipment transport unit 12 to transport another equipment holder 11 to the work area Ar1 in place of the equipment holder 11 located in the work area Ar1 (S105).

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

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

[0100] The syringe transport control unit 141 terminates this process if it determines that a predetermined time has elapsed since the syringe 5011 was not detected (YES in S107). On the other hand, if the syringe transport control unit 141 determines that a predetermined time has not elapsed since the syringe 5011 was not detected (NO in S107), it continues the process in 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 on the touch panel 80 indicating that there is no needle (S106). This allows the user to recognize syringes 501 that are unsuitable for injection. Note that the processes in S102 and S103 are not necessarily performed.

[0102] (modified version) In this embodiment, as described above, the syringe transport control unit 141 changes the equipment holding unit 11 located in the work area Ar1 to another equipment holding unit 11 when it detects user action, such as when the object detection unit 13 detects the user's hand and then stops detecting the user's hand. However, it is not limited to this, and for example, the syringe transport control unit 141 may transport another equipment holding unit 11 in place of the equipment holding unit 11 located in the work area Ar1 when it receives a transport instruction from the user. The syringe transport control unit 141 may receive transport instructions from the user, for example, via the touch panel 80.

[0103] [Vial shelf configuration] The detailed configuration of the vial rack 20 will be explained below based on Figures 13 to 17. Figure 17 is a diagram illustrating the equipment holding section 21.

[0104] As shown in Figures 13 to 15, the vial rack 20 comprises a plurality of equipment holding units 21, an equipment transport unit 22, an object detection unit 23, and a vial detection unit 24. Furthermore, as shown in Figures 16 and 17, it includes a first reading unit 25 (reading unit) and a roller drive unit 26. In the vial rack 20, components related to the transport of vials 502 are controlled by the vial transport control unit 142. Note that an equipment holding unit 21 is also attached to the mounting portion 221 of the equipment transport unit 22 shown in Figure 13, but its illustration is omitted.

[0105] Prior to the injection process, the vial racks 20 are filled with vials 502 by the user. Also, similar to the syringe racks 10, multiple holes 172 are formed in the plate-shaped members 171 that define each vial rack 20.

[0106] The equipment holding portion 21 is a member capable of holding the vial 502. In this embodiment, one vial 502 is held in one equipment holding portion 21, but multiple vials 502 may be held in one equipment holding portion 21.

[0107] In this embodiment, as shown in Figures 16 and 17, the equipment holding section 21 includes a pair of free rollers 211, a pair of equipment clamping sections 212, a drive roller 213, and a first magnet 214.

[0108] The pair of equipment clamping parts 212 clamp the vial 502. In this embodiment, the pair of equipment clamping parts 212 clamp the neck portion of the vial 502. Also in this embodiment, the pair of equipment clamping parts 212 are provided on the upper part of the vial rack 20. The pair of equipment clamping parts 212 are provided at a height such that the vial 502 does not touch the plate-shaped member 171 when the vial 502 is held in the equipment holding part 21.

[0109] The pair of instrument clamping portions 212 are biased toward each other so that they can clamp the vial 502. In this embodiment, when the pair of instrument clamping portions 212 are not clamping the neck of the vial 502, they are spaced apart to a degree smaller than the width of the neck. When the neck is inserted between the pair of instrument clamping portions 212, the pair of instrument clamping portions 212 move to conform to the shape of the neck. As a result, the pair of instrument clamping portions 212 can clamp the vial 502.

[0110] The tips of the pair of equipment clamping parts 212 are provided with a pair of free rollers 211 that have a rotation axis extending in the vertical direction and are rotatable in the XY plane. The pair of free rollers 211, together with a drive roller 213 located on the side where the pair of equipment clamping parts 212 are pivotally supported and opposite the center of the pair of free rollers 211, hold the vial 502 by supporting the neck of the vial 502 at three points. When the drive roller 213 rotates while the vial 502 is held, the vial 502 also rotates. The pair of free rollers 211 also rotate in conjunction with this rotation. By providing the pair of free rollers 211 at the tips of the pair of equipment clamping parts 212, the possibility of the rotational force of the vial 502 being reduced by the tips can be reduced.

[0111] A first magnet 214 is provided on the upper part of the drive roller 213. The drive roller 213 and the first magnet 214 are connected to a common rotation axis that extends in the vertical direction and are rotatable in 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, causing the drive roller 213 to rotate as well. In this embodiment, the outer surfaces of the first magnet 214 and the second magnet 261 have alternating south poles and north poles.

[0112] The equipment transport unit 22 is a component that transports at least one of the multiple equipment holding units 21 to the work area Ar2. In this embodiment, the equipment transport unit 22 is an endless rotating member to which multiple equipment holding units 21 are connected. Therefore, in this embodiment, the equipment transport unit 22 transports the equipment holding units 21 one by one to the work area Ar2. However, the equipment transport unit 22 may be a transport unit that transports multiple equipment holding units 21 to the work area Ar2 at once. The work area Ar2, like the work area Ar1, is an area where the user holds the vial 502 in at least one of the multiple equipment holding units 21. The work area Ar2 is also an area where the user removes the vial 502 held in at least one of the multiple equipment holding units 21. In this embodiment, the work area Ar2 is located on the side of the vial-side door 27 shown in Figure 1. The vial-side door 27 functions as a door that can block user access to the work area Ar2. Furthermore, the working area Ar2 may function solely as a region for holding vial 502, or solely as a region for removing vial 502, similar to the working area Ar1.

[0113] In this embodiment, the equipment transport unit 22 has the same functions as the equipment transport unit 12 described below. That is, the equipment transport unit 22 transports a different equipment holder 21 in place of the equipment holder 21 located in the work area Ar2, triggered by the detection of user movement. The equipment transport unit 12 changes the equipment holder 21 located in the work area Ar2 by, for example, rotating counterclockwise. The equipment transport unit 22 transports a different equipment holder 11 to the work area Ar2, triggered by the object detection unit 23 detecting the user movement described above. In this embodiment, in addition to detecting user movement, the equipment transport unit 12 also transports a different equipment holder 11 to the work area Ar2 when the vial detection unit 24 detects a vial 502 held in the equipment holder 21. With these configurations, the equipment transport unit 22 can achieve the same effects as the equipment transport unit 12.

[0114] Furthermore, similar to the syringe transport control unit 141, the vial transport control unit 142 may, for example, triggered by a transport instruction from the user, transport a different equipment holding unit 21 instead of the equipment holding unit 21 located in the work area Ar2. The vial transport control unit 142 may receive transport instructions from the user, for example, via the touch panel 80.

[0115] The vial 502 is equipped with a rubber stopper to seal the opening and a lid that fits over the rubber stopper. The needle of the syringe 501 held in the injection unit 40 is punctured into the rubber stopper. The vial 502 is filled into the vial shelf 20 with the lid removed. For example, a camera (not shown) may be installed on the vial shelf 20, and the top of the vial 502 may be imaged with the camera. In this case, the control unit 140 can determine whether or not the lid is present based on the image captured by the camera. If the lid is attached to the vial 502, the touch panel control unit 149 may display an image on the touch panel 80 prompting the user to fill the vial 502 into the equipment holding unit 21 with the lid removed.

[0116] The object detection unit 23 is a component that detects an object inserted into the work area Ar2. In this embodiment, the object detection unit 23 detects the user's hand or arm when it is inserted into the work area Ar2. The arrangement of the object detection unit 23 in the vial rack 20 is the same as the arrangement of the object detection unit 13 in the syringe rack 10, and the specific example and function of the object detection unit 23 are also the same as those of the object detection unit 13.

[0117] The vial detection unit 24 detects vials 502 held in the equipment holding unit 21 located in the work area Ar2. In other words, the vial detection unit 24 functions as an equipment detection unit that detects injection equipment held in the equipment holding unit 21 located in the work area Ar2. The arrangement of the vial detection unit 24 in the vial rack 20 is the same as the arrangement of the syringe detection unit 14 in the syringe rack 10, and the specific example and function of the vial detection unit 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, in a part of the transport path in which the equipment transport unit 22 transports a plurality of equipment holding units 21. The vial 502 may have a barcode on which the type information is recorded. In this case, the first reading unit 25 may be a barcode reader.

[0119] As shown in Figures 16 and 17, the first reading unit 25 is positioned to read the barcode of the vial 502 that has been transported to a predetermined position. In this embodiment, the predetermined position may be the position where the first transport unit 110 takes out the vial 502. By reading the barcode at the position where the vial 502 is taken out, the control unit 140 can recognize the type of drug contained in the vial 502 immediately before taking it out. Therefore, the first transport unit 110 can transport the vial 502 that is appropriate to be transported to the injection unit 40. In this embodiment, the first reading unit 25 is positioned behind the predetermined position when the vial shelf 20 is viewed from the first transport 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, when a user holds a vial 502 in each of the multiple equipment holding units 21, the barcode (type information) shown on each of the multiple vials 502 can be read sequentially when the vial-side door 27 is closed. Therefore, the barcode reading by the first reading unit 25 can be performed efficiently.

[0121] Furthermore, when the equipment transport unit 22 detects that the vial-side door 27 is closed, if the vial 502 is not present at the barcode reading position by the first reading unit 25, the equipment transport unit 22 may transport the vial 502 to that position. Also, after the first reading unit 25 has finished reading the barcode of the vial 502, the equipment 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] As shown in Figure 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 equipment holding unit 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. As a result, the second magnet 261 is rotatable in 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 the barcode reading position by the first reading unit 25.

[0123] As described above, the first magnet 214 of the equipment holding section 21 is positioned on the upper part of the equipment holding section 21. The positioning of the equipment holding section 21 and the roller drive section 26 is defined such that the first magnet 214 and the second magnet 261 are separated by a distance that allows them to receive each other's magnetic fields.

[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. In conjunction with the rotation of the first magnet 214, the drive roller 213, which is connected to the same rotation axis as the first magnet 214, rotates, causing the vial 502 in contact with the drive roller 213 to rotate. As the vial 502 rotates in this way, the first reading unit 25 can read the barcode regardless of 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 receive the user's reading instruction, for example, via the touch panel 80.

[0126] (Process to initiate transport of the equipment holding unit) Reference numeral 18002 in Figure 18 is a flowchart showing an example of the process when the vial transport control unit 142 starts transporting the equipment holding unit 21.

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

[0128] If the vial transport control unit 142 determines that it has detected the user's hand (YES in S201), it determines whether or not the vial detection unit 24 has detected vial 502 (S202). When the vial transport control unit 142 receives a detection signal from the vial detection unit 24, it determines that it has detected vial 502.

[0129] If the vial transport control unit 142 determines that the vial detection unit 24 has detected the syringe 5011 (YES in S202), it determines whether or not the user's hand inserted into the work area Ar2 is no longer detected (S204), similar to S104 of reference numeral 18001.

[0130] If the vial transport control unit 142 determines that the user's hand is no longer detected (YES in S204), it controls the equipment transport unit 22 to transport another equipment holding unit 21 to the work area Ar2 in place 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 it has not detected vial 502 (NO in S202), it determines whether a predetermined time has elapsed since vial 502 was not detected, similar to S107 of reference numeral 18001 (S205).

[0132] (Other processing) To improve the filling efficiency of the vial 502 held in the equipment holding section 21, for example, the following processes may be performed. Figure 19 is a diagram illustrating the improvement of the filling efficiency of the vial 502 held in the equipment holding section 21. Note that the filling efficiency improvement examples described below may also be applied to the filling efficiency of the syringe 501 held in the equipment holding section 11.

[0133] (Example 1 of improving filling efficiency) In Figure 19, reference numeral 19001 indicates a state in which two equipment holding sections 21, which do not hold vials 502, are located in separate positions. In Figure 19, reference numeral 19002 indicates a state in which two equipment holding sections 21, which do not hold vials 502, are located in adjacent positions.

[0134] In some cases, two or more of the multiple equipment holding sections 21 may not be holding the vial 502. Equipment holding sections 21 that do not hold the vial 502 can also be referred to as empty equipment holding sections 21. Furthermore, if two or more empty equipment holding sections 21 occur, it is possible that at least two of these empty equipment holding sections 21 are located in positions that are not adjacent to each other. Such a situation can occur, for example, when the first transport section 110 transports the vial 502 used for the injection process to the injection unit 40. In the example shown by reference numeral 19001 in Figure 19, there are two sets of two empty equipment holding sections 21, and these empty equipment holding sections 21 are located in positions that are not adjacent to each other.

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

[0136] If the control unit 140 determines that the two empty equipment holding units 21 are not adjacent, it will perform the following processing, for example, during the idle time of the first transport unit 110. As shown by reference numeral 19002 in Figure 19, the control unit 140 moves the vial 502 held in the equipment holding unit 21 so that the empty equipment holding units 21 are adjacent. For example, the equipment transport unit 22, under the control of the vial transport control unit 142, transports the equipment holding unit 21 that is adjacent to the empty equipment holding unit 21 to the position where the first transport unit 110 will take out the vial 502. The first transport unit 110, under the control of the first transport control unit 143, takes out the vial 502 and holds it. As a result, the two empty equipment holding units 21 are adjacent. In this state, the equipment transport unit 22 transports the other empty equipment holding unit 21 to the position where the first transport unit 110 will take out the vial 502. The first transport unit 110 holds the vial 502 to be held in the empty equipment holding unit 21.

[0137] In the case of reference numeral 19001 in Figure 19, consider the case where vials 502 are filled into an empty equipment holder 21 in the work area Ar2, and then vials 502 are filled into another empty equipment holder 21. In this case, the equipment transport unit 22 needs to move the other empty equipment holder 21, which is located some distance from the equipment holder 21 that has been filled with vials 502, to the work area Ar2. In the case of reference numeral 19002 in Figure 19, the two empty equipment holders 21 are located adjacent to each other, so the distance to be moved can be shortened compared to the case of reference numeral 19001 in Figure 19. Therefore, the time interval between filling one equipment holder 21 with vials 502 and filling the next equipment holder 21 with vials 502 can be shortened.

[0138] (Example 2 of improving filling efficiency) Figure 19 shows an example where there are multiple adjacent empty equipment holding sections 21. When the vial side door 27 is opened (i.e., when it becomes possible to fill the vial 502 into the equipment holding section 21), the vial transport control unit 142 searches for adjacent empty equipment holding sections 21. The vial transport control unit 142 determines the order in which the empty equipment holding sections 21 are transported to the work area Ar2, starting from the section with the largest number of consecutively adjacent empty equipment holding sections 21. In the example of Figure 19003, the vial transport control unit 142 determines the transport order to be the section SP3 of three consecutively adjacent empty equipment holding sections 21, the section SP2 of two adjacent empty equipment holding sections 21, and the single empty equipment holding section 21 (section SP1). The equipment transport unit 22 transports these sections SP1 to SP3 to the work area Ar2 in this transport order. In this case, vials 502 can be filled in order from the section with the most consecutively adjacent empty equipment holding sections 21. Therefore, in this case as well, the time interval mentioned above can be shortened.

[0139] [Configuration of IV fluid shelves] Figures 20 and 21 are perspective views showing an example of the configuration of the IV drip shelf 30. Figure 21 shows the IV drip shelf 30 with a portion of the wall removed. Figure 22 is a perspective view showing an example of the IV drip shelf 30 viewed from the rear.

[0140] As shown in Figures 20 and 21, the infusion shelf 30 includes a push-in section 31, a first infusion detection section 32, a push-in transport section 35, and a pair of rail sections 36 (extension sections). Also, as shown in Figure 22, it includes a second infusion detection section 33 and a shutter 37. In this embodiment, as described above, the infusion shelf 30 includes an infusion shelf 30S and an infusion shelf 30L, but the only difference between the infusion shelf 30S and the infusion shelf 30L is their size; their internal mechanisms are identical. Furthermore, the components related to the transport of the infusion container 503 in the infusion shelf 30 are controlled by the push-in control section 147.

[0141] Prior to the injection process, the infusion shelves 30 are filled with infusion containers 503 by the user. Furthermore, similar to the syringe shelves 10 and vial shelves 20, multiple holes 302 are formed in the plate-shaped members 301 that define each infusion shelf 30.

[0142] The pair of rail sections 36 are provided inside the infusion shelf 30 and extend from the infusion side door 34 (see Figure 1) towards the back of the injection device 1 (i.e., in the Y-axis direction). As shown in Figure 21, the end of the pair of rail sections 36 located on the infusion side door 34 can also be called the door side end 361, and the end located towards the back of the injection device 1 can be called the back side end 362. At least one infusion container 503 can be suspended from the pair of rail sections 36. In this embodiment, the neck of the infusion container 503 can be suspended between the pair of rail sections 36. That is, the pair of rail sections 36 are provided with a gap large enough to hold the neck of the infusion container 503. By providing the pair of rail sections 36, when filling the infusion shelf 30 with multiple infusion containers 503, the user only needs to sequentially suspend the multiple infusion containers 503 from the pair of rail sections 36. Therefore, the user can easily fill multiple infusion containers 503 into the infusion rack 30.

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

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

[0145] The push-in section 31 is located at position PO0 on the door-side end 361 side when the infusion-side door 34 is open, and does not interfere with the filling of the infusion container 503 (suspending it to the pair of rail sections 36). The push-in control unit 147 may move the push-in section 31 to the above position by controlling the push-in transport section 35, for example, when the button 90 (see Figure 1) on the infusion shelf 30 is pressed (when the infusion-side door 34 is open).

[0146] The push-in unit 31 pushes the infusion container 503, suspended from the pair of rail sections 36, from the door-side end 361 to the rear end 362, triggered when the infusion-side door 34 is closed. In this embodiment, when the infusion-side door 34 is closed, the push-in control unit 147 controls the push-in transport unit 35 to move the push-in unit 31 from the above position PO0 to the rear end 362. As a result, the user can move the infusion container 503 to the rear end 362 simply by filling the door-side end 361, and have the second transport unit 120 retrieve the infusion container 503. In other words, the second transport unit 120 can efficiently retrieve the infusion container 503 suspended from the pair of rail sections 36.

[0147] Furthermore, consider the case where multiple infusion containers 503 are suspended from a pair of rail sections 36, and the second transport section 120 removes an infusion container 503 located at the rear end 362. After the second transport section 120 removes the infusion container 503, the push section 31 pushes the remaining infusion containers 503 suspended from the pair of rail sections 36 from the door-side end 361 to the rear end 362. In this embodiment, when the second transport section 120 removes an infusion container 503 located at the rear end 362, the push control section 147 controls the push transport section 35 to move the push section 31 further towards the rear end 362. This allows the remaining infusion containers 503 suspended from the pair of rail sections 36 to be moved towards the rear end 362 after the infusion containers 503 have been removed from the pair of rail sections 36. 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 filled in the infusion shelf 30. The first infusion detection unit 32 may also detect infusion containers 503 being removed from the infusion shelf 30. In other words, the first infusion detection unit 32 may function as a count sensor that counts the number of infusion containers 503 filled in 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 of the wall portion constituting 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 an optical sensor equipped with an emitter and a light receiver, similar to the object detection unit 13 described above.

[0149] In this embodiment, the first infusion detection unit 32 is provided with two sensors adjacent to each other in the Y-axis direction. For example, if the sensor on the infusion side door 34 outputs a detection signal, and then the sensor further back outputs a detection signal, the control unit 140 may recognize that the pair of rail sections 36 have been filled with infusion containers 503. For example, if the sensor further back than 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 the infusion containers 503 filled in the pair of rail sections 36 have been removed. This allows the control unit 140 to count the number of infusion containers 503 suspended from the pair of rail sections 36. Therefore, the control unit 140 can manage the inventory of infusion containers 503 filled in the infusion shelf 30. Also, for example, if the inventory falls below a preset standard inventory number, the touch panel control unit 149 may display an image on the touch panel 80 prompting the user to refill the infusion containers 503.

[0150] As shown in Figure 22, the second infusion detection unit 33 is provided at the rear end 362 of the wall portion constituting the infusion rack 30 and detects the infusion container 503 located at the rear end 362. The second infusion detection unit 33, like the first infusion detection unit 32, is provided for each pair of rail portions 36 and may be an optical sensor comprising an emitter and a light receiver. For example, when the second infusion detection unit 33 detects the infusion container 503 at the rear end 362, it outputs a detection signal.

[0151] The push-in control unit 147 may, for example, determine that the infusion container 503 located at the rear end 362 has been removed by the second transport unit 120 if it has received a detection signal from the second infusion detection unit 33 and then no longer receives the same detection signal. Based on this determination, the push-in unit 31 can push the remaining infusion container 503 suspended from the pair of rail units 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 in the rear direction (+Y-axis direction). The shutter 37 is controlled by the control unit 140 to be movable in the vertical direction. For example, when the infusion side door 34 is closed, the shutter 37 is controlled by the control unit 140 to be located at the rear 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 from the pair of rails 36 when the push-in 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 addition, when the second transport unit 120 removes the infusion container 503, the shutter 37 moves to an infusion shelf 30 other than the one in which the infusion container 503 is stored.

[0153] (Processing of the push-in control unit) Figure 23 is a flowchart illustrating an example of the processing performed by the push-in control unit 147. Figure 23 describes the processing performed by the push-in control unit 147 when the user closes the infusion side door 34.

[0154] As shown in Figure 23, the push-in control unit 147 determines whether the infusion side door 34 is in the closed state (S301). If the push-in control unit 147 determines that the infusion side door 34 is not in the closed state (NO in S301), it continues the process in S301.

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

[0156] The push control unit 147 determines whether the second transport unit 120 has removed the infusion container 503 from the pair of rail sections 36 (S303). For example, the push control unit 147 determines that the infusion container 503 has been removed by the second transport unit 120 when the detection signal from the second infusion detection unit 33 is interrupted. If the push control unit 147 determines that the second transport unit 120 has not removed the infusion container 503 (NO in S303), it continues the process in S303.

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

[0158] In addition, the push-in control unit 147 may, in S302, control the push-in transport unit 35 to push the infusion container 503 suspended from the pair of rail units 36 from the door-side end 361 to the rear-side end 362, triggered by a push-in instruction from the user. The push-in control unit 147 may receive the user's push-in instruction, for example, via the touch panel 80.

[0159] (modified version) The mechanism for transporting the infusion container 503 in the infusion rack 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 rack 10.

[0160] In other words, the infusion rack 30 may be provided with multiple equipment holding units and equipment transport units instead of the push-in unit 31, push-in transport unit 35, and pair of rail units 36. In this case, the multiple equipment holding units are members capable of holding infusion containers 503. The equipment transport unit is a member that transports at least one of the multiple equipment holding units to the work area. The work area is the area where the user has the equipment holding unit hold the infusion container 503, and / or where the user removes the infusion container 503 held by the equipment holding unit. Furthermore, the equipment transport unit may transport a different equipment holding unit in place of an equipment holding unit located in the work area, triggered by detection of user action or a transport instruction from the user. In this modified example, the infusion container 503 is an example of an injection device used for injection.

[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 viewed from the rear. Figure 26 is a perspective view showing an example of the internal configuration of the printing and inspection unit 50. Note that the measuring unit 52 is not shown in Figures 24 and 25. Also, Figure 24 shows an example of the infusion container 503 being positioned in the printing and inspection unit 50 by the suction of the second transport unit 120.

[0162] As shown in Figures 23 to 25, the printing and inspection unit 50 comprises a printing unit 51, a weighing unit 52, a second reading unit 53, an adhesive 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 the printing and inspection unit control unit 148.

[0163] The printing unit 51 prints a type information label LA1 which includes type information indicating the type of drug mixed by the injection unit 40 with the infusion solution in the infusion container 503. The printing unit 51 may, for example, dispense a type information label LA1 in which the type information is printed in barcode format. The printing unit 51 also prints an unsuitable information label LA2 which includes unsuitable information, as described later.

[0164] As shown in Figure 5, the printing and inspection unit control unit 148 includes an inspection unit 1481. The inspection unit 1481 performs inspection of the infusion container 503 after drug injection.

[0165] In this embodiment, the inspection unit 1481 determines, based on the weighing result of the weighing unit 52, whether the prescribed amount of drug indicated in the preparation data has been injected into the infusion container 503 after drug injection. 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 weighed 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] Furthermore, the inspection unit 1481 determines, based on the reading results of the second reading unit 53, whether or not the appropriate type information label LA1 has been affixed to the infusion container 503 after drug injection. The inspection unit 1481 determines whether the drug indicated by the type information contained in the barcode read by the second reading unit 53 is the drug injected into the infusion container 503 from which the barcode was read (i.e., whether it is the drug 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 acceptable, 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 unacceptable, the printing unit 51 prints an unacceptable information label LA2 containing unacceptable information. The unacceptable information label LA2 may be printed if the weight measured by the weighing unit 52 is unacceptable. That is, the unacceptable information may be information indicating that the weight measured by the weighing unit 52 is unacceptable. However, the unacceptable information label LA2 may also be printed if the reading result of the second reading unit 53 is unacceptable. In this case, the unacceptable information may be information indicating that the reading result of the second reading unit 53 is unacceptable.

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

[0169] The weighing unit 52 weighs the infusion container 503 after drug injection. In this embodiment, the weighing unit 52 also weighs the infusion container 503 before drug injection. In this embodiment, as shown in Figure 24, the weighing unit 52 is equipped with a pair of locking parts 521 that lock onto the neck of the infusion container 503. The weighing unit 52 can weigh the infusion container 503 by locking the neck of the infusion container 503 to the pair of locking parts 521 when the second transport unit 120 locks onto the neck of 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 drug injection. The second reading unit 53 is, for example, a barcode reader.

[0171] The attachment unit 54 attaches the type information label LA1 to the infusion container 503 after drug injection. For example, the attachment unit 54 attaches the type information label LA1 to the infusion container 503 after drug injection before inspection by the inspection unit 1481. Subsequently, if the inspection result by the inspection unit 1481 is unsuitable, the attachment unit 54 attaches the unsuitable information label LA2 to the infusion container 503 after drug injection. In this case, the attachment unit 54 may attach the unsuitable information label LA2 to a position that does not overlap with the printed position of the type information contained in the type information label LA1. This ensures that even when the unsuitable information label LA2 is attached, the user can still visually confirm the type information.

[0172] In this embodiment, the attachment unit 54 includes an adsorption mechanism 541 and a moving mechanism 542, as shown in Figure 25. The type information label LA1 and the unsuitable information label LA2 printed by the printing unit 51 are dispensed to a position above the tray 511, which is positioned substantially horizontally to the XY plane. The adsorption mechanism 541 adsorbs the type information label LA1 or unsuitable information label LA2 dispensed onto the tray 511, thereby enabling the attachment unit 54 to hold the type information label LA1 or unsuitable information label LA2. The moving mechanism 542 can move the adsorption mechanism 541 from above the tray 511 to the tray 511, or in the reverse direction (i.e., vertically). The moving mechanism 542 can also move the adsorption mechanism 541 between the tray 511 and the attachment position PO1 (see Figure 26) where the type information label LA1 or unsuitable 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 attachment part 54 to attach the type information label LA1 or the unsuitable information label LA2 held in the tray 511 to the infusion container 503 after drug injection at the attachment position PO1. The adsorption mechanism 541 releases the adsorption of the type information label LA1 or the unsuitable information label LA2 at the attachment position PO1.

[0173] Furthermore, the pair of guide sections 56 shown in Figure 26 guide the movement of the type information label LA1 or unsuitable information label LA2 to the infusion container 503 after drug injection when the attachment section 54 attaches the type information label LA1 or unsuitable information label LA2 to the infusion container 503 after drug injection. Specifically, the pair of guide sections 56 are provided so as to be able to swing in the XY plane. Therefore, when the second transport section 120 presses the infusion container 503 after drug injection against the type information label LA1 or unsuitable information label LA2 located at the attachment position PO1, the pair of guide sections 56 swing in the XY plane. In addition, the pair of guide sections 56 are each provided with springs 561 at both ends. Therefore, when the second transport section 120 presses the infusion container 503 after drug injection against the type information label LA1 or unsuitable information label LA2 located at the attachment position PO1, the pair of guide sections 56 swing in the YZ plane. As the pair of guide sections 56 swing in this manner, the attachment section 54 can attach the type information label LA1 or the unsuitable information label LA2 to the infusion container 503 after drug injection, following the shape of the surface to which it is pressed. Therefore, the type information label LA1 or the unsuitable information label LA2 can be attached to the infusion container 503 after drug injection more reliably.

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

[0175] (Processing by the Printing and Inspection Control Unit) Figure 27 is a flowchart showing an example of the processing of the printing and inspection unit control unit 148. As shown in Figure 27, the second transport control unit 145 transports the infusion container 503 before drug injection from the infusion rack 30 to the weighing unit 52 by controlling the second transport unit 120. When the infusion container 503 before drug injection is locked to 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 infusion container 503, which has been weighed and is not yet injectable, to the injection unit 40. The injection unit control unit 144 starts the injection process (S402). Next, the printing and inspection unit control unit 148 controls the printing unit 51 to print the type information label LA1 (S403). In other words, the printing unit 51 starts printing the type information label LA1 before the inspection unit 1481 outputs the judgment result.

[0177] Conventional drug injection devices begin printing the drug type information label only after determining that the prescribed amount of drug has been injected into the infusion container. In contrast, the printing and inspection unit 50 begins printing the drug type information label LA1 without waiting for the inspection unit 1481's determination result. Therefore, the printing and inspection unit 50 can affix the drug type information label LA1 to the infusion container 503 after drug injection faster than conventional devices.

[0178] When the injection unit control unit 144 finishes the injection process (S404), the printing and inspection unit control unit 148 controls the attachment unit 54 to attach 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 drug injection to the weighing unit 52, where the weighing unit 52 weighs the infusion container 503 after 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 drug injection and the weight of the infusion container 503 after the injection process (S407). Then, the inspection unit 1481 determines whether the difference calculated in S407 matches the prescribed amount of drug injected into the infusion container 503 as shown in the preparation data (S408).

[0181] If the inspection unit 1481 determines that the difference calculated in S407 matches the prescribed amount of drug shown in the preparation data (YES in S408), it causes the second reading unit 53 to read the barcode of the type information label LA1. Subsequently, the inspection unit 1481 determines whether the type of drug injected in the compounding 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 drug injection, but before the determination in S409 is performed. In other words, the type information label LA1 only needs to be printed and affixed to the infusion container 503 after drug injection before the reading process by the second reading unit 53 is performed.

[0183] If the inspection unit 1481 determines that the two types of 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 drug shown in the preparation data (NO in S408), the printing and inspection unit control unit 148 executes the process in S411. Also, if the inspection unit 1481 determines that the type of drug injected in the injection process does not match the type of drug prescribed (NO in S409), the printing and inspection unit control unit 148 executes the process in S411.

[0185] In S411, the printing and 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 and inspection unit control unit 148 controls the attachment unit 54 to attach the printed unsuitable information label LA2 to the infusion container 503 after drug injection, on which the type information label LA1 has been attached (S412). In this way, if the inspection result is unsuitable, the unsuitable information label LA2 is attached after the type information label LA1 has been attached to the infusion container 503 after drug injection, so the type information label LA1 can be attached without waiting for the inspection result. In other words, the injection device 1 can be allowed to attach the type information label LA1 to the infusion container 503 after drug injection before the inspection unit 1481 outputs the judgment result. In addition, in S412, the printing and inspection unit control unit 148 may control the attachment unit 54 to attach the unsuitable information label LA2 to a position that does not overlap with the printing position of the barcode on the type information label LA1.

[0186] (Method of attaching type information labels and unsuitability information labels) Figure 28 is a diagram illustrating the method of attaching the type information label LA1 and the unsuitable information label LA2 to the infusion container 503. Reference numeral 28001 in Figure 28 shows the state in which the infusion label containing the label information is attached to the body 5031 of the infusion container 503. Reference numeral 28002 in Figure 28 shows the state in which the type information label LA1 is attached to the body 5031 of the infusion container 503. Reference numeral 28003 in Figure 28 shows the state in which the type information label LA1 and the unsuitable information label LA2 are attached to the body 5031 of the infusion container 503.

[0187] As shown by reference numeral 28001 in Figure 28, an intravenous fluid label is affixed to the body 5031 of the intravenous fluid container 503 by the pharmaceutical manufacturer that provides the container 503. The label information includes information about the intravenous fluid injected into the container by the pharmaceutical manufacturer (e.g., information indicating the type of intravenous fluid). The label information may be in barcode format. In addition, the label information may include, for example, information indicating the type of intravenous fluid, information indicating the pharmaceutical manufacturer, the composition of the intravenous fluid, the volume, the expiration date, and the manufacturing number, which may be printed on the intravenous fluid label in text or the like.

[0188] As shown by reference numeral 28002 in Figure 28, the attachment portion 54 may attach the type information label LA1 in the same orientation as the infusion label attached by the pharmaceutical manufacturer (the orientation in which the infusion information is printed). In other words, the attachment portion 54 may attach the type information label LA1 to the infusion container 503 after drug injection so that the upper part of the type information label LA1 faces the bottom side of the infusion container 503 after drug injection.

[0189] For example, when administering an intravenous drip, the infusion container 503 is used with its bottom facing vertically upwards. Therefore, by attaching the type information label LA1 as described above, users can easily read the type information from the type information label LA1 when using the infusion container 503.

[0190] The type information label LA1 has textual information printed on it, such as patient ID, patient name, ward name, department name, room name, date of administration, name of the infusion, and name of the injected drug (an example of type information). In addition, the type information label LA1 has a barcode BC printed on it, which includes, for example, the patient ID and type information. The barcode BC is printed so that when the type information label LA1 is attached to the infusion container 503, the longitudinal direction of the barcode BC is approximately parallel to the longitudinal direction of the infusion container 503 (the direction approximately perpendicular to the bottom). This reduces 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 have the weighing result from the weighing unit 52 printed on it. This allows the type information label LA1 to be affixed to the infusion container 503 before inspection based on the weighing result from the weighing unit 52. As a result, inspection time can be shortened.

[0192] As shown by reference numeral 28003 in Figure 28, the attachment section 54 may attach the unsuitable information label LA2 to a position that does not overlap with the printed position of the type information included in the type information label LA1, so that the user can visually confirm the type information. The unsuitable information label LA2 may be attached to a position that does not overlap with the printed position of information other than the type information included in the type information label LA1, as described above. In this case, the user can also easily visually confirm the information other than the type information. The unsuitable information may be indicated by, for example, letters or symbols. For example, the unsuitable information may be an "X" mark.

[0193] Furthermore, by attaching the unsuitable information label LA2 to a position offset from the type information label LA1, users can easily peel off the unsuitable information label LA2.
