[0040] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0041] Combination Figure 1-9As shown, this embodiment of the present disclosure provides an apparatus for dispensing medicine, including: a housing 100, a dispensing module 200, and an infusion bag placement part 300. The upper side wall of the housing 100 is provided with a vial clamping part 400 for clamping vials, and the lower inner wall is provided with an ampoule clamping part 500 for clamping ampoules. The dispensing module 200 is slidably disposed within the housing 100 and located between the vial clamping part 400 and the ampoule clamping part 500. The infusion bag placement part 300 is disposed on one side of the vial clamping part 400 or the ampoule clamping part 500 for placing the infusion bag. The dispensing module 200 includes a rotating part 210 and a needle moving part 220. The needle moving part 220 is provided with a needle. The rotating part 210 can drive the needle moving part 220 to rotate between the vial clamping part 400 and the ampoule clamping part 500 so that the needle in the needle moving part 220 can draw the medicine in the vial, ampoule and infusion bag for dispensing.

[0042] In this embodiment, vial clamping portions 400 and ampoule clamping portions 500 are respectively provided on the upper and lower side walls of the housing 100 to clamp and fix the medication contained in the vial and ampoule, respectively. An infusion bag is placed inside the infusion bag placement portion 300, and a medication preparation module 200 is positioned between the vial clamping portions 400 and 500. The medication preparation module 200 is divided into a rotating portion 210 and a needle movement portion 220. The rotating part 210 drives the needle movement part 220 to rotate, so that the needle fixed in the needle movement part 220 can rotate to a position facing the vial clamping part 400 or the ampoule clamping part 500. The needle draws or injects the medicine into the vial and the ampoule respectively. Then, by controlling the sliding of the drug preparation module 200, the needle moves to a position facing the infusion bag, and the needle draws or injects the medicine into the infusion bag, thus completing the preparation of intravenous injection drugs.

[0043] The medication dispensing apparatus provided in this embodiment, by including an vial clamping part 400 and an ampoule clamping part 500, can simultaneously hold medications contained in vials and ampoules, enabling simultaneous medication dispensing between vials, ampoules, and infusion bags. This adapts to diverse medication dispensing environments and meets diverse medication dispensing needs. By incorporating a sliding medication dispensing module 200, which consists of a rotating part 210 and a syringe moving part 220, the dispensing action can be completed simply by the sliding and rotating motion of the module itself. This improves medication dispensing accuracy and efficiency while simplifying the dispensing structure and reducing costs.

[0044] Optionally, the housing 100 defines an operating cavity 110, within which the dispensing module 200 is movably disposed. The vial holder 400 is located in the upper region of the operating cavity 110, and the ampoule holder 500 is located in the lower region of the operating cavity 110. In this way, by movably dispensing the dispensing module 200 within the operating cavity 110, the sliding and vertical rotation of the dispensing module 200 allows for the extraction or injection of medication into vials and ampoules. The housing 100 provides protection for the dispensing module 200, reducing the risk of contamination from the external environment and minimizing the risk of injury from the dispensing module 200.

[0045] Optionally, the front side wall of the housing 100 is provided with an operating port, which connects to the operating cavity 110. In this way, ampoules can be placed into the ampoule holding part 500 through the operating port, and the dispensing module 200 can also be maintained.

[0046] Optionally, multiple vial holders 400 and ampoule holders 500 are provided, and all multiple vial holders 400 and ampoule holders 500 are arranged along the sliding direction of the dispensing module 200. In this way, by providing multiple vial holders 400 and ampoule holders 500, multiple vials and ampoules can be placed simultaneously for medication dispensing, further improving dispensing efficiency and adapting to diverse dispensing needs. By arranging multiple vial holders 400 and ampoule holders 500 along the sliding direction of the dispensing module 200, the dispensing module 200 can drive the syringe to the mouth position of each vial and ampoule simply by sliding, thereby facilitating the extraction or injection of medication through the syringe.

[0047] Specifically, multiple vial clamping parts 400 are evenly arranged along the upper side wall of the housing 100, and multiple ampoule clamping parts 500 are evenly arranged along the lower inner wall of the housing 100. This arrangement of multiple vials along the upper side wall of the housing 100 and multiple ampoules along the lower inner wall of the housing 100 facilitates the dispensing module 200 in drawing or injecting medication into different vials and ampoules.

[0048] Understandably, multiple vial clamping parts 400 can be of the same model or different models, thus accommodating the clamping and placement of various models of vials; multiple ampoule clamping parts 500 can also be of the same model or different models, thus accommodating the clamping and placement of various models of ampoules to meet diverse medication needs.

[0049] In some embodiments, such as Figure 1As shown, multiple infusion bag placement sections 300 are provided, and these multiple infusion bag placement sections 300 are arranged along the sliding direction of the dispensing module 200 in conjunction with multiple vial clamping sections 400 or multiple ampoule clamping sections 500. In this way, by providing multiple infusion bag placement sections 300 to simultaneously hold multiple infusion bags, and cooperating with the multiple vial clamping sections 400 and multiple ampoule clamping sections 500, multi-station dispensing operations are achieved, further improving dispensing efficiency.

[0050] Optionally, the infusion bag placement part 300 is located on one side of the vial clamping part 400, and is arranged together with the vial clamping part 400 along the sliding direction of the dispensing module 200. In this way, the infusion bag placement part 300 located on one side of the vial clamping part 400 is also located on the upper side wall of the housing 100, which facilitates the dispensing module 200 to move to the position of the infusion bag placement part 300 to draw or inject the medicine into the infusion bag.

[0051] Optionally, the infusion bag placement part 300 includes an inclined support plate 310 and a clamping seat 320. The clamping seat 320 is disposed through the upper side wall of the housing 100, and the inner side of the clamping seat 320 is provided with a through clamping hole 321. The front side wall of the clamping seat 320 is provided with a snap-fit ​​opening. The inclined support plate 310 is disposed above the clamping seat 320. In this way, the infusion bag body is placed by the inclined support plate 310, and the mouth of the infusion bag is fixed in place by snapping it into the clamping hole 321 through the snap-fit ​​opening. Since the infusion bag body is placed at an inclination, pressure is applied to the mouth of the bag under the action of gravity. When the needle in the drug dispensing module 200 is inserted into the mouth of the bag, the pressure of the bag body makes it more difficult for the mouth of the bag to fall out of the restriction of the clamping hole 321.

[0052] Optionally, multiple infusion bag placement sections 300 and multiple vial clamping sections 400 are arranged together along the sliding direction of the medication preparation module 200. In this way, the medication preparation module 200 can smoothly slide to the position of the infusion bag placement section 300 or the vial clamping section 400, which facilitates the extraction or injection of medication into the infusion bag or vial.

[0053] Specifically, there are two infusion bag placement sections 300, and the two infusion bag placement sections 300 are located on both sides of the multiple vial clamping sections 400. In this way, by setting two infusion bags and placing them on both sides of the multiple vial clamping sections 400, the sliding stroke of the medication dispensing module 200 during medication dispensing can be shortened.

[0054] Optionally, such as Figure 1 and Figure 2As shown, a slide rail 120 is provided inside the housing 100. The slide rail 120 is arranged along the sliding direction of the dispensing module 200. The dispensing module 200 is slidably mounted on the slide rail 120 via a drive seat 130, which is limited to slide on the slide rail 120. In this way, with the slide rail 120 provided inside the housing 100 and the dispensing module 200 mounted on the slide rail 120 via the drive seat 130, the dispensing module 200 is driven to slide along the slide rail 120 via the drive seat 130. This allows the needle of the dispensing module 200 to slide to the positions of the vial clamping part 400, the ampoule clamping part 500, and the infusion bag placement part 300, so as to draw or inject medication into the vial, ampoule, and infusion bag.

[0055] Specifically, the slide rail 120 is fixedly mounted on the rear inner wall of the housing 100. In this way, while providing a sliding track for the dispensing module 200 through the slide rail 120, the influence of the slide rail 120 on the rotation of the syringe movement module is reduced.

[0056] For example, the drive base 130 is a sliding bracket with a drive motor. The sliding bracket is slidably mounted on the slide rail 120. The drive motor is fixedly mounted on the sliding bracket. The outer wall of the slide rail 120 has a rack. The output end of the drive motor meshes with the rack. The output end of the drive motor rotates to drive the sliding bracket to slide on the slide rail 120. The drive motor is equipped with a limit switch. The processor of the dispensing device is connected to the limit switch. The limit switch is controlled to control the drive stroke of the drive motor, thereby controlling the sliding position of the dispensing module 200.

[0057] Optionally, such as Figure 3 As shown, the rotating part 210 includes a support frame 211 and a first motor 212. One end of the support frame 211 is fixedly connected to the drive seat 130. The inner side of the support frame 211 has an installation space, and the needle moving part 220 is rotatably installed in the installation space. The first motor 212 is fixedly disposed on one side of the support frame 211, and the output shaft of the first motor 212 passes through the side wall of the support frame 211 and is connected to the needle moving part 220. In this way, the support frame 211 is connected to the drive seat 130, and the drive seat 130 drives the support frame 211 to slide along the slide rail 120, so that the needle moving part 220 is rotatably installed inside the support frame 211. The first motor 212 drives the needle moving part 220 to rotate, so that the needle in the needle moving part 220 can rotate to a position facing the vial clamping part 400 or the ampoule clamping part 500, and the medicine is drawn or injected into the vial, ampoule, or infusion bag through the needle.

[0058] Specifically, the support frame 211 includes a first arm and a second arm. The ends of both the first and second arms are fixedly connected to the drive seat 130, forming an installation space between them. The needle movement part 220 is rotatably disposed between the first and second arms via a rotating shaft structure. The output shaft of the first motor 212 passes through the side wall of the first arm and is connected to the rotating shaft structure. Thus, by forming the support frame 211 with the first and second arms, the needle movement part 220 is installed between the first and second arms. The rotation of the output shaft of the first motor 212 drives the needle movement part 220 to rotate, improving the stability of the needle movement part 220.

[0059] Optionally, such as Figure 4 and Figure 5 As shown, the needle movement unit 220 includes: a support 221, a guide rail 222, a needle telescopic seat 223, and a suction seat 224. The support 221 is rotatably disposed within the installation space; the guide rail 222 is disposed on the side wall of the support 221; the needle telescopic seat 223 is slidably disposed on the guide rail 222, and the needle is disposed within the needle telescopic seat 223; the suction seat 224 is slidably disposed on the guide rail 222, and one end of the needle's suction piston rod is connected to the suction seat 224; wherein, the needle telescopic seat 223 and the suction seat 224 can slide opposite to each other or backward along the guide rail 222 to drive the needle to perform suction or injection actions. In this way, by setting a guide rail 222 on the side wall of the support 221, both the needle telescopic seat 223 and the aspiration seat 224 are mounted on the guide rail 222. The needle is mounted on the needle telescopic seat 223, and the end of the aspiration piston rod of the needle is fixed to the aspiration seat 224. By driving the needle telescopic seat 223 and the aspiration seat 224 to slide in opposite directions along the guide rail 222, the needle is driven to perform aspiration or injection actions. The guide rail 222 guides both the needle telescopic seat 223 and the aspiration seat 224 simultaneously, ensuring that the needle can stably perform aspiration or injection actions during the insertion action, improving the stability of the needle and preventing the needle from deviating from its insertion direction during aspiration or injection actions.

[0060] Optionally, the support 221 includes a guide plate 225, a clamping plate 226, and a connecting seat 227. The guide plate 225 is disposed on the inner side of the clamping plate 226, and the guide rail 222 is disposed on the side wall of the guide plate 225. One side wall of the clamping plate 226 is rotatably connected to the inner side wall of the support frame 211, and the other side is fixedly connected to the connecting seat 227. The side wall of the connecting seat 227 facing away from the clamping plate 226 is rotatably connected to the other inner side wall of the support frame 211. In this way, the support 221 is divided into the guide plate 225, the clamping plate 226, and the connecting seat 227. The clamping plate 226 and the connecting seat 227 are rotatably connected to the inner side wall of the support frame 211 through their cooperation. The guide plate 225 is disposed on the inner side of the clamping plate 226, and the guide rail 222 is disposed on the side wall of the guide plate 225. The guide plate 225 supports the guide rail 222, which can improve the stability of the guide rail 222.

[0061] Specifically, the opposing sidewalls of the clamping plate 226 and the connecting seat 227 are rotatably mounted inside the support frame 211 via a rotating shaft structure. The output shaft of the first motor 212 is connected to the rotating shaft structure on one side of the connecting seat 227. In this way, the first motor 212 drives the connecting seat 227 and the clamping plate 226 to rotate, thereby driving the guide plate 225 located inside the clamping plate 226 to rotate, which in turn drives the needle telescopic seat 223 and the suction seat 224 on the guide rail 222 to rotate.

[0062] Optionally, a second motor 228 is provided inside the clamping plate 226. The second motor 228 is located on the side of the guide plate 225 opposite to the guide rail 222. A first connecting arm 229 is provided on one side of the needle telescopic seat 223. The first connecting arm 229 extends across the guide plate 225 and into one side of the second motor 228. The portion of the first connecting arm 229 located on the side of the second motor 228 has a first screw hole 230. The output shaft of the second motor 228 is connected to a first screw 231, which passes through the first screw hole 230. In this way, by setting the second motor 228 to drive the first screw 231 to rotate, the first connecting arm 229 is driven to move through the engagement of the first screw 231 with the first screw hole 230. This drives the needle telescopic seat 223 connected to the first connecting arm 229 to slide, so that the needle telescopic seat 223 drives the needle to perform puncture or withdrawal actions. The extension and retraction of the needle telescopic seat 223 is driven by the meshing of the first screw 231 and the first screw hole 230, which can improve the sliding stability of the needle telescopic seat 223 and reduce the space occupied.

[0063] Optionally, the axis of the first screw 231 is parallel to the guide rail 222. Thus, since the rotation of the first screw 231 drives the first connecting arm 229 to move along the axis of the first screw 231, setting the axis of the first screw 231 parallel to the guide rail 222 allows the driven needle telescopic seat 223 to slide more stably along the guide rail 222, further improving the stability of the needle puncture or withdrawal action.

[0064] Optionally, the inner side of the first connecting arm 229 has a clearance notch, through which the guide plate 225 and the guide rail 222 pass. This allows the first connecting arm 229 to smoothly connect the needle telescopic seat 223 and the first screw 231, and avoids interference between the first connecting arm 229 and the guide plate 225 and the guide rail 222, ensuring the normal sliding of the needle telescopic seat 223.

[0065] Optionally, a third motor 232 is provided on the side wall of the connecting seat 227. The output end of the third motor 232 is connected to a second screw 233. A second connecting arm 234 is provided on the suction seat 224. The portion of the second connecting arm 234 located on one side of the second screw 233 has a second screw hole 235, through which the second screw 233 passes. In this way, the third motor 232 drives the second screw 233 to rotate, thereby driving the second connecting arm 234 to move through the engagement of the second screw 233 with the second screw hole 235. The second connecting arm 234 drives the suction seat 224 to slide along the guide rail 222, thereby driving the suction piston rod of the syringe to move, thus performing suction or injection actions. The driving method of the second screw 233 engaging with the second screw hole 235 can improve the sliding stability of the suction seat 224, thereby driving the suction piston rod to perform more uniform suction or injection actions and improving the drug preparation effect.

[0066] Optionally, the axis of the second screw 233 is arranged parallel to the guide rail 222. This allows the suction seat 224 to slide more stably along the guide rail 222.

[0067] Optionally, such as Figure 5 and Figure 6 As shown, the inner side of the needle telescopic base 223 is provided with a receiving groove 236, and the needle body is placed in the receiving groove 236. The end of the receiving groove 236 facing away from the aspiration base 224 has an opening 237, through which the needle tip of the needle extends to the outside. In this way, with the needle body placed in the receiving groove 236 and the needle tip extending to the outside through the opening 237, when the needle telescopic base 223 is driven to perform the insertion action, the needle tip inserts into one of the vial, ampoule, and infusion bag to draw or inject medication. This improves the stability of the needle and allows the needle tip to insert smoothly.

[0068] Specifically, the suction seat 224 is located on the side of the syringe telescopic seat 223 facing away from the opening 237. In this way, since the needle of the syringe extends through the opening 237, and the suction piston rod of the syringe is positioned opposite to the needle, placing the suction seat 224 on the side of the syringe telescopic seat 223 facing away from the opening 237 facilitates the connection between the end of the suction piston rod and the suction seat 224.

[0069] Optionally, the suction seat 224 is provided with an embedding groove, in which the end handle of the suction piston rod is embedded. This facilitates the fixing of the end of the suction piston rod and also facilitates the disassembly of the syringe.

[0070] Combination Figure 7 , Figure 8 and Figure 9As shown, in some embodiments, the vial clamping part 400 is disposed through the upper side wall of the housing 100, and the inner side of the vial clamping part 400 has a through-hole 410, with an elastic retaining ring 420 disposed inside the hole 410. Thus, by distributing the vial clamping part 400 through the upper side wall of the housing 100, the nozzle of the clamped vial can face the interior of the housing 100, facilitating the extraction or injection of medication into the vial. The nozzle of the vial is engaged with the elastic retaining ring 420 inside the hole 410, which restricts the nozzle of the vial, preventing it from easily falling off when subjected to puncture force. The elastic retaining ring 420 also provides protection for the nozzle of the vial.

[0071] Specifically, when the vial is placed inside the vial clamping part 400, the vial nozzle is positioned facing inwards from the housing 100.

[0072] Optionally, the vial clamping part 400 has a locking inlet on one side, and the elastic retaining ring 420 has a notch corresponding to the locking inlet. In this way, the vial nozzle is locked into the elastic retaining ring 420 through the locking inlet and the notch, making it easy to put the vial away.

[0073] Optionally, the ampoule holding part 500 has a groove 510 on its inner side, and the ampoule is placed in the groove 510. The inner wall of the groove 510 is provided with an elastic coating 520. In this way, since the ampoule cannot be placed upside down when dispensing medicine, and the ampoule is thin and easily broken, placing the ampoule in the groove 510 on the inner side of the ampoule holding part 500 and using the elastic coating 520 to protect the ampoule reduces the risk of breakage.

[0074] Optionally, the ampoule clamping part 500 is inclined. Since ampoules cannot be placed upside down during medication preparation, and to increase the amount of medication extracted from the ampoule, it is usually necessary to place the ampoule at an angle. Therefore, by tilting the ampoule clamping part 500, the placed ampoule has an inclined angle, which facilitates increasing the amount of medication extracted from the ampoule.

[0075] Optionally, a rotatable base 140 is provided on the lower inner wall of the housing 100, and the ampoule holding part 500 is disposed on the base 140. In this way, to facilitate the placement and removal of ampoules placed in the ampoule holding part 500, the ampoule holding part 500 is disposed on the rotatable base 140. After the medication is prepared, the base 140 is rotated so that the ampoule holding part 500 tilts towards the operating port, which facilitates the removal of ampoules and the insertion of new ampoules.

[0076] For example, the base 140 is rotatably mounted inside the housing 100 via a bearing structure. The bearing structure has a limiting block, which allows the base 140 to stop rotating to a certain angle in the direction away from the operating port. When it is necessary to insert an ampoule into the ampoule holding part 500, the base 140 rotates in the direction of the operating port, causing the ampoule holding part 500 to tilt in the direction of the operating port, which facilitates the placement of the ampoule. After the ampoule is placed, the base 140 can rotate in the direction away from the operating port until the bearing structure is locked by the limiting block, which facilitates the extraction or injection of the medicine in the ampoule.
