Description

TECHNICAL FIELD

[0001] The present application relates to the field of dispensing equipment, in particular to a medicine bottle workbench based on a ring-shaped conveying belt. BACKGROUND

[0002] In the field of intravenous drug preparation automation, various automatic dispensing equipment has appeared in the prior art, aiming to replace manual operations such as extracting solvent from ampoules, injecting into a vial to mix with powder, and then filling the mixed liquid into a transfusion bag.

[0003] In related technologies, a dispensing machine disclosed in Chinese patent CN120531610A has the following technical points: a frame is provided inside which a medicine bottle box for storing ampoules and vials, a liquid bag box for storing liquid bags, and a suction and injection device hanger are arranged. The frame is provided with an ampoule opening device for opening the ampoule, a vial cap opening device for opening the cap of the vial, a vial liquid mixing device for mixing and shaking the liquid injected into the ampoule, and a marking device for marking the liquid bag after injection of the mixed liquid. The frame is provided with a suction and injection manipulator for clamping the suction and injection device and sucking the liquid in the ampoule to inject into the vial. The devices are transferred by a transfer manipulator.

[0004] In the above-mentioned scheme, the medicine bottles need to be grabbed, transported and placed by the manipulator multiple times, from the medicine box to the opening station, then to the liquid extraction station, then to the injection station, and finally to the mixing station. Each transfer consumes time, and each placement needs to be accurately positioned, which increases the complexity and risk of errors, and the overall work efficiency is low. SUMMARY

[0005] In order to improve the work efficiency of the dispensing process, the present application provides a medicine bottle workbench based on a ring-shaped conveying belt.

[0006] The medicine bottle workbench based on a ring-shaped conveying belt provided by the present application adopts the following technical scheme: A medicine bottle workbench based on a ring-shaped conveying belt, comprising a base and a conveying mechanism and a transfusion mechanism arranged on the base, the conveying mechanism comprising a conveying belt and a support arranged on the conveying belt, the support being provided with multiple groups and being arranged along the extension direction of the belt surface of the conveying belt, the support being used for carrying ampoules, vials and transfusion bags, a clamping mechanism and a shaking mechanism being arranged between the base and the support; The clamping mechanism comprises a first clamping assembly and a second clamping assembly, the first clamping assembly comprising a driving part and two clamping plates, the driving part being used for driving the two clamping plates to slide reversely and clamp the ampoules and vials, the second clamping assembly comprising a placing rack and a limiting spring plate arranged on the circumferential side of the placing rack, the limiting spring plate being used for pressing the transfusion bag against the placing rack. The infusion mechanism comprises a first infusion assembly for transferring the medicine liquid in the ampoule to the vial to mix the medicine liquid with the powder in the vial, and a second infusion assembly for delivering the mixed medicine liquid in the vial to the infusion bag. The shaking mechanism is connected with the first clamping assembly, and is configured to drive the first clamping assembly to shake to mix the medicine liquid and the powder in the vial.

[0007] By adopting the above technical solution, the ampoule, the vial and the infusion bag required in the dispensing process are integrated on the same support moving along the conveying belt, which serves as a mobile work unit and sequentially passes through different functional areas such as the loading area, the liquid injection area and the unloading area to complete the dispensing process. This is fundamentally different from the background art in which the mechanical hand repeatedly picks up, transfers and places the medicine bottles between different stations. The medicine bottles and the infusion bags do not need to be transferred between stations, thereby eliminating the time consumption and positioning errors of material transfer, significantly simplifying the equipment structure, reducing the complexity of the control system, and ultimately greatly improving the overall efficiency and operation stability of the automatic dispensing. Moreover, during the transfer of the medicine liquid, the mixing and the injection process, the other part of the conveying belt can perform the loading and unloading process of the medicine bottles and the infusion bags, so that the loading and unloading process does not affect the transfer and injection process of the medicine liquid, thereby ensuring the continuous injection process and improving the work efficiency.

[0008] Optionally, the support comprises a first sliding table and a second sliding table, both of which are connected with the conveying belt and are arranged in a spaced manner along the extension direction of the belt surface of the conveying belt.

[0009] By adopting the above technical solution, the support is designed as a first sliding table and a second sliding table, which facilitates the installation of the components for clamping the medicine bottles and the components for placing the infusion bags. This not only simplifies the manufacturing and assembly process, but also improves the flexibility of the layout, so that the corresponding parts can be easily adjusted or replaced according to the different sizes of the medicine bottles or the infusion bags, thereby enhancing the versatility and maintainability of the equipment. It can also avoid the problem that the overall size of the support is too large to affect the stability of the movement along the conveying belt, thereby ensuring the smooth progress of the dispensing process.

[0010] Optionally, the driving component comprises a mounting base, a sliding block, a traction member, a first elastic member and a first power telescopic member, the clamping plate is in sliding connection with the mounting base, the sliding block is provided with two and is in sliding connection with the mounting base, the sliding direction of the sliding block is perpendicular to the sliding direction of the clamping plate, the traction member is provided with two groups and each group of the traction member corresponds to a sliding block, the traction member comprises a first connecting rod and a second connecting rod, the first connecting rod and the second connecting rod are in rotary connection with the corresponding sliding block, one end of the first connecting rod away from the sliding block is in rotary connection with one of the clamping plates, one end of the second connecting rod away from the sliding block is in rotary connection with the other clamping plate, the first elastic member is located between the two sliding blocks and is connected with the two sliding blocks respectively, the first elastic member is used to drive the two sliding blocks to approach each other, and the first power telescopic member is connected with the base and is used to drive one of the clamping plates to slide away from the other clamping plate.

[0011] By adopting the above technical scheme, the first elastic member makes the two sliding blocks approach each other, so that the two clamping plates have a tendency to slide to the side of approaching each other, thereby clamping the ampoule or the syringe through the two clamping plates; when it is needed to loosen the clamping of the medicine bottle, the first power telescopic member drives one of the clamping plates to slide to the side away from the mounting base, so that the two clamping plates slide reversely, thereby loosening the clamping of the medicine bottle by the clamping plates, and thus reliable clamping and releasing actions can be realized in a smaller space; the clamping of the medicine bottle is realized through the first elastic member, the clamping force is not too large, the medicine bottle is not easy to be crushed, and the clamping process does not need other power sources, and only when it is needed to loosen the clamping, one of the clamping plates needs to be pushed outward, thereby helping to ensure stable clamping, improve the reliability of clamping and realize energy saving and consumption reduction; since the first power telescopic member is arranged on the base, only the first power telescopic member needs to be arranged at the feeding station and the discharging station, and the first power telescopic member does not rotate with the conveying belt, so that the normal work of the gas supply, power supply or liquid supply line of the first power telescopic member can be ensured, and the first power telescopic member is not easy to be wound.

[0012] Optionally, a placing groove for placing the bottom of the ampoule or the syringe is arranged on the mounting base, and the placing groove is provided with a plurality of and is arranged in intervals.

[0013] By adopting the above technical scheme, the arrangement of the placing groove can provide a preliminary positioning reference for the ampoule and the syringe before the clamping of the clamping plate, and can effectively prevent the medicine bottle from being tilted or displaced during the movement of the conveying belt or the clamping process, thereby ensuring the correctness of the posture of the medicine bottle and providing a guarantee for the subsequent automatic operation such as accurate insertion of the infusion needle.

[0014] Optionally, the placing groove is arranged in an inclined manner compared to the height direction of the base.

[0015] By adopting the technical scheme, the ampoule or the vial placed in the placing groove is also arranged in an inclined manner, and the inclined groove bottom causes the medicine bottle to be naturally arranged in an inclined manner after being placed. On one hand, when the liquid is drawn, the inclination can cause the liquid in the bottle to gather at the lowest point on one side, so that the infusion needle can draw the liquid completely, reduce residue, and improve the utilization rate of the medicine. On the other hand, when the liquid is injected and mixed, the inclined bottle body is also beneficial to the injection of the liquid along the bottle wall, and reduces the generation of impact and bubbles.

[0016] Optionally, the two clamping plates are each provided with an abutting block on the side close to each other, the abutting block is abutted against the bottle body of the ampoule or the vial, and the abutting block is elastic, and is used to drive the two clamping plates to clamp the ampoule and the vial at the same time.

[0017] By adopting the technical scheme, the elastic abutting block can adapt to ampoules and vials of different diameters by using the elastic deformation of the abutting block itself, so that the same pair of clamping plates can clamp two kinds of medicine bottles with size difference at the same time, thereby enhancing the versatility and adaptability of the clamping mechanism, and the clamps do not need to be replaced or adjusted for different medicine bottles.

[0018] Optionally, the first infusion assembly includes a peristaltic pump, a hose, a first infusion needle and a storage box, one section of the hose is located in the pump head of the peristaltic pump and is driven by the peristaltic pump to transport fluid, the first infusion needle is connected to the first end of the hose, the first end of the hose is used to be connected with the movable end of the mechanical arm, and the second end of the hose is located in the storage box and is used to transfer the liquid in the ampoule to the storage box and the vial in turn. The second infusion assembly includes a second power telescopic member, an infusion tube, a second infusion needle and a connector, the second infusion needle is connected to the first end of the infusion tube, the connector is connected to the second end of the infusion tube, the connector is used to be connected with the first infusion needle, so that the liquid in the first infusion needle is transported into the infusion tube, and the second power telescopic member is used to drive the second infusion needle to slide and is used to insert the second infusion needle into or out of the infusion bag.

[0019] By adopting the above technical solution and using a peristaltic pump for drug delivery, the drug solution only comes into contact with the sterile tubing throughout the entire process, without contacting the pump body, fundamentally avoiding cross-contamination. It also facilitates quick tubing replacement, meeting high medical and hygiene standards, and replaces frequently replaced disposable syringes, reducing operating costs. Connecting the tubing of the first and second infusion components via connectors forms a closed delivery loop, reducing the drug solution's contact with the external environment during transfer and further ensuring the sterility of the medication. The first infusion component is responsible for the extraction and mixing of the drug solution, while the second infusion component is dedicated to injecting the mixed medication into the infusion bag. The cooperation of the first and second infusion components constructs a complete automated infusion process, which is more efficient. Using a peristaltic pump for drug delivery minimizes liquid residue in the tubing, thus helping to ensure accurate quantitative delivery of the drug solution.

[0020] Optionally, the rocking mechanism includes a mounting plate, a rocking plate, a driving gear, a driven gear, an eccentric shaft, and a power assembly. The mounting plate is connected to the first slide table. The driving gear and the driven gear are both rotatably connected to the mounting plate. The driving gear meshes with the driven gear. Multiple driven gears are arranged in a circular array. The eccentric shaft is eccentrically connected to the driven gear and connected to the rocking plate. The rocking plate is connected to the first clamping assembly. The power assembly is driven by the driving gear and is used to drive the driving gear to rotate and drive the driven gear and the eccentric shaft to rotate, so that the rocking plate moves along a circular trajectory.

[0021] By adopting the above technical solution, the power component drives the drive gear to rotate, the drive gear drives the driven gear to rotate, the driven gear drives the eccentric shaft to rotate, and the eccentric shaft drives the rocking plate to move along a circular trajectory in the horizontal plane, thereby causing the mounting base on the rocking plate and the medicine bottle to shake, accelerating the mixing of liquid and powder in the vial, and helping to enhance the mixing effect; since there are multiple eccentric shafts, the rocking plate can be evenly stressed, which helps to improve the stability of the rocking plate during the shaking process.

[0022] Optionally, the power assembly includes a rotating power component, a connecting frame, a connecting shaft, and a connecting block. The connecting shaft is coaxially connected to the drive gear, and the connecting block is connected to the end of the connecting shaft away from the drive gear. The rotating power component is mounted on the base, and the output shaft of the rotating power component is connected to the connecting frame. One side of the connecting frame is open to allow the connecting block to be inserted, so that when the connecting frame rotates, it drives the connecting block to rotate together. The insertion direction of the connecting block is perpendicular to the rotation axis of the connecting frame.

[0023] By adopting the above technical solution, when the connecting block is inserted into the connecting frame, the rotating power component drives the connecting frame to rotate, which in turn causes the connecting block to rotate. The connecting block then drives the connecting shaft to rotate, causing the drive gear to rotate, thus driving the drive gear. Since the rotating power component and the connecting frame are mounted on the base, only the rotating power component and the connecting frame need to be installed at the suction station, eliminating the need for a power source at each first slide, which reduces the number of power sources and helps to lower equipment costs. In addition, since the rotating power component is mounted on the base and does not rotate with the conveyor belt, the wires used to connect the rotating power component will not rotate with the movement of the conveyor belt, making it less likely for the wires to become tangled, thereby further ensuring the reliability of the equipment.

[0024] Optionally, the rocking plate is provided with a pull rod, and a second elastic element is connected between the pull rod and the mounting plate. The second elastic element is used to drive the connecting block into a state in which it can be inserted into the connecting frame.

[0025] By adopting the above technical solution, during the shaking of the swaying plate, the second elastic element can deform accordingly with the movement of the pull rod; when the swaying plate stops shaking, the restoring force of the second elastic element can reset the pull rod to its initial state. At this time, the swaying plate is not easy to shake under the action of external force, thus ensuring the stability of the subsequent drug transfer process; in addition, under normal conditions, the second elastic element tightens the pull rod, so that the connecting block is in a state that can be inserted into the connecting frame, thus facilitating the insertion of the connecting block into the connecting frame, so that the subsequent rotating power component can drive the drive gear to rotate smoothly.

[0026] In summary, this application includes the following beneficial technical effects: 1. By integrating ampoules, vials, and infusion bags onto the same support that moves along a circular conveyor belt, the inefficient process of repeatedly grabbing and transferring materials in existing technologies is replaced, significantly shortening the single dispensing cycle. At the same time, it reduces the reliance on complex multi-axis robotic arms, simplifies the overall equipment structure and control system, and helps to greatly improve production efficiency and simplify the equipment structure.

[0027] 2. The designed clamping mechanism achieves synchronous clamping through a connecting rod, and through a two-stage buffer structure with elastic elements and elastic abutment blocks, it can adaptively and simultaneously clamp ampoules and vials of different diameters, applying force evenly and effectively preventing damage to the glass bottles, thus ensuring material safety during transportation and processing.

[0028] 3. The use of peristaltic pumps and tubing avoids cross-contamination of medications and reduces consumable costs. At the same time, the dedicated infusion assembly automates the entire process from drawing and mixing the medication to injecting it into the infusion bag. The entire process takes place in a closed pipeline, maximizing the sterility of the medication. Attached Figure Description

Detailed Implementation

[0031] The following combination Figures 1-9 This application will be described in further detail.

[0032] Example 1 This application discloses a medicine bottle workbench based on a circular conveyor belt. (Refer to...) Figure 1 The medicine bottle workbench based on a circular conveyor belt includes a fixed base 1, which is vertically oriented. A circular conveying mechanism 2 and an infusion mechanism 3 for dispensing medicine are mounted on the top surface of the base 1. The conveying mechanism 2 includes a conveyor belt 21 and a support member 22; the conveyor belt 21 includes a belt body, pulleys, and a motor; two pulleys are arranged in parallel and spaced apart, with their axes vertically oriented, and the belt body is wound around the outside of the two pulleys; the motor is fixedly mounted on the base 1, and its output shaft is coaxially and fixedly connected to one of the pulleys, thus allowing the belt body to rotate continuously or in steps.

[0033] On the outer surface of the conveyor belt 21, multiple sets of identical support members 22 are fixedly installed at intervals. These support members 22 are evenly spaced along the belt surface extension direction of the conveyor belt 21. Each set of support members 22 serves as an independent moving working unit, used to carry all the materials required for one dispensing operation. The materials include ampoules 6, vials 7, and infusion bags 8. Among them, the ampoules 6 are in the state where the bottle neck has been broken off, and the vials 7 are in the state where the cap has been opened. The ampoules 6 contain liquid medicine, the vials 7 contain solid powder or granular powder, and the infusion bags 8 are flexible bags containing liquid medicine.

[0034] Along the direction of the conveyor belt 21, the base 1 is sequentially equipped with a medicine bag loading station 9, a medicine bottle loading station 10, an infusion station 11, and a discharging station 12. The medicine bag loading station 9 is equipped with a loading mechanism that mates with the workbench of this application, used to transfer the infusion bag 8 onto the support member 22. The medicine bottle loading station 10 is equipped with a loading mechanism that mates with the workbench of this application, used to transfer the opened ampoule 6 and the opened vial 7 onto the support member 22. The infusion mechanism 3 is located in the infusion station 11, which can transfer the liquid medicine in the ampoule 6 to the vial 7 and mix it with the powder in the vial 7, then inject the mixed medicine into the infusion bag 8 to complete the drug preparation process. The discharging station 12 is equipped with a discharging mechanism used to remove the infusion bag 8 after drug addition, as well as the empty ampoule 6 and vial 7. Therefore, as the conveyor belt 21 continues to operate, the mixing and injection of the drug solution can be carried out continuously and efficiently, resulting in high overall work efficiency.

[0035] The support member 22 includes a first slide 221 and a second slide 222, both of which are connected to the conveyor belt 21 and can operate together with the conveyor belt 21. Both the first slide 221 and the second slide 222 are detachably connected to the conveyor belt 21, thus their installation positions can be adjusted as needed. The first slide 221 and the second slide 222 are arranged at intervals along the extension direction of the conveyor belt 21. The first slide 221 is used to support ampoules 6 and vials 7, and the second slide 222 is used to support infusion bags 8.

[0036] A clamping mechanism 5 and a shaking mechanism 4 are provided between the base 1 and the first slide 221. The clamping mechanism 5 is used to firmly fix the bottle body throughout the conveying and processing process, and the shaking mechanism 4 is used to shake the vial 7 to ensure that the medicine injected into the vial 7 is fully mixed. The conveyor belt 21 carries the support member 22 through the medicine bag loading station 9, the medicine bottle loading station 10, the aspiration station 11, and the unloading station 12 in sequence, thereby completing the medicine preparation process. The clamping mechanism 5, the infusion mechanism 3, and the shaking mechanism 4 are described in sequence below.

[0037] Reference Figure 1 andFigure 2 The clamping mechanism 5 includes a first clamping assembly 51 for clamping the medicine bottle and a second clamping assembly 52 for fixing the infusion bag 8. The second clamping assembly 52 includes a placement frame 521 and a limiting spring 522. The placement frame 521 includes a support block 5211 and a support plate 5212. The support block 5211 is fixedly installed on the second slide table 222. The support block 5211 has a snap-fit ​​groove 5211a for inserting the bag opening of the infusion bag 8. The support plate 5212 is inclined, and the lower end of the support plate 5212 is fixedly connected to the support block 5211. The top surface of the support plate 5212 is used to abut against the bottom wall of the infusion bag 8. Four limiting springs 522 are provided, and are fixedly connected to the four corners of the support plate 5212 respectively. The limiting springs 522 are V-shaped, with the openings of the limiting springs 522 facing the side closest to the support plate 5212. The limiting springs 522 are made of plastic and are elastic. In other embodiments, the limiting springs 522 can also be made of metal. Therefore, by pressing the infusion bag 8 downward and making the bottom wall of the infusion bag 8 abut against the support plate 5212, and at the same time inserting the opening of the infusion bag 8 into the snap-fit ​​groove 5211a on the support block 5211, the limiting springs 522 can be pressed tightly and fastened to the four corners of the infusion bag 8, thereby fixing the position of the infusion bag 8 and preventing the infusion bag 8 from shaking or falling during movement, which facilitates the stability of the subsequent drug administration process.

[0038] Reference Figure 3 and Figure 4 The first clamping assembly 51 is used to simultaneously clamp the ampoule 6 and the vial 7. The first clamping assembly 51 includes two clamping plates 512 that can move in opposite directions and a driving component 511 for driving the clamping plates 512 to move. The driving component 511 includes a mounting base 5111, a slider 5112, a traction member 5113, a first elastic member 5114, and a first power telescopic member 5115 (see reference). Figure 6 The mounting base 5111 is connected to the first slide 221. The mounting base 5111 is a rectangular block structure. Multiple placement slots 5111a are evenly spaced along the length of the top wall of the mounting block. Each placement slot 5111a is a circular slot. In this embodiment, five placement slots 5111a are provided. In other embodiments, the number of placement slots 5111a may be more or less, such as three, four, or six. The placement slots 5111a are used to place the bottom of the ampoule 6 or vial 7, and each placement slot 5111a can only hold one vial.

[0039] Reference Figure 4 and Figure 5Each of the two clamping plates 512 has a guide rod 5121 vertically fixedly connected to one side of each other. The guide rod 5121 is arranged along the width direction of the mounting base 5111. The guide rods 5121 on the two clamping plates 512 are arranged in parallel at intervals, so that the guide rods 5121 on the two clamping plates 512 are staggered to avoid interference. The mounting base 5111 has a through guide hole 5111b, and the guide rod 5121 slides through the guide hole 5111b, so that the clamping plate 512 is slidably connected to the mounting base 5111, thereby improving the stability of the clamping plate 512 during the sliding process. Two sliders 5112 are provided and are arranged at intervals along the length of the mounting base 5111. A slide rail 5111d is fixedly connected to the bottom wall of the mounting base 5111 along its own length. A slide groove 5112a is provided on the top wall of the slider 5112. The slide groove 5112a slides with the slide rail 5111d, so that the slider 5112 is slidably connected to the bottom wall of the mounting base 5111. Two sets of traction members 5113 are provided. The first set of traction members 5113 corresponds to one of the sliders 5112, and the second set of traction members 5113 corresponds to the other slider 5112.

[0040] Reference Figure 4 The traction component 5113 includes a first connecting rod 5113a and a second connecting rod 5113b. A vertically arranged hinge post 5112b is fixedly connected to the bottom wall of the slider 5112. One end of the first connecting rod 5113a is hinged to the hinge post 5112b, and the other end of the first connecting rod 5113a is hinged to one of the clamping plates 512. One end of the second connecting rod 5113b is hinged to the hinge post 5112b, and the other end of the second connecting rod 5113b is hinged to the other clamping plate 512. The first elastic element 5114 is a tension spring, which is fixedly connected between the hinge posts 5112b on the two sliders 5112. The first elastic element 5114 is in a stretched state, thus causing the two sliders 5112 to slide towards each other. Since the clamping plate 512 can only slide along the width direction of the mounting base 5111, under the restriction of the first link 5113a and the second link 5113b, the two sliders 5112 slide towards each other, thus bringing the two clamping plates 512 closer together and clamping the bodies of the ampoule 6 and the vial 7. Conversely, when the two sliders 5112 slide away from each other, the two clamping plates move away from each other, releasing the clamping of the ampoule 6 and the vial 7. Therefore, under normal conditions, the first elastic element 5114 can be used to clamp the medicine bottle. In other embodiments, the first elastic element 5114 can also be an elastic rope.

[0041] Reference Figure 6The first power telescopic component 5115 is a cylinder. The cylinder body of the first power telescopic component 5115 is fixedly connected to the base 1. The piston rod of the first power telescopic component 5115 faces the mounting seat 5111. A clearance hole 14 is provided in the middle of a clamping plate 512 near the base 1 and the mounting seat 5111. The clearance hole 14 on the clamping plate 512 and the mounting seat 5111 are coaxially arranged. The diameter of the clearance hole 14 is larger than the diameter of the piston rod of the first power telescopic component 5115. The clearance hole 14 allows the piston rod of the first power telescopic component 5115 to be inserted. Therefore, the piston rod of the first power telescopic member 5115 extends and passes into the clearance hole 14, so that the end of the piston rod abuts against the clamping plate 512 on the side away from the base 1; then the piston rod continues to extend, which can push the clamping plate 512 to slide away from the base 1. Under the action of the hinge column 5112b and the first connecting rod 5113a and the second connecting rod 5113b, the clamping plate 512 on the side close to the base 1 can slide to the side close to the base 1, so that the two clamping plates 512 move away from each other and release the clamping of the medicine bottle.

[0042] It should be noted that multiple first power telescopic components 5115 are provided, with one first power telescopic component 5115 installed on the base 1 at both the bottle loading station 10 and the unloading station 12. At the bottle loading station 10, the piston rod of the first power telescopic component 5115 extends to drive the two clamping plates 512 away from each other, facilitating the transfer of the bottle to the placement slot 5111a via the loading mechanism. Then, the piston rod retracts, allowing the two clamping plates 512 to move closer together via the first elastic member 5114, clamping and securing the bottle. At the unloading station 12, the first power telescopic component 5115 drives the two clamping plates 512 away from each other again, facilitating the removal of the bottle via the unloading mechanism. Then, the piston rod retracts and slides out of the clearance hole 14, thus preventing the piston rod from interfering with the movement of the mounting base 5111. In other embodiments, the first power telescopic component 5115 can also be a hydraulic cylinder or an electric push rod.

[0043] Reference Figure 5 In this device, a mounting ring 5111c is fixedly connected to the inner wall of the guide hole 5111b on the mounting base 5111. The mounting ring 5111c is a circular ring, and the inner diameter of the mounting ring 5111c is larger than the diameter of the guide rod 5121, so that the guide rod 5121 can pass smoothly through the mounting ring 5111c. A spring is fixedly connected between the guide rod 5121 and the mounting ring 5111c. The spring is sleeved on the outside of the guide rod 5121, thus playing a protective and buffering role.

[0044] In addition, each of the two clamping plates 512 has a resilient abutment block 13 installed on its adjacent side. Five abutment blocks 13 are provided on each clamping plate 512, corresponding to the five placement slots 5111a. The adjacent sides of the abutment blocks 13 on the two clamping plates 512 are provided with V-shaped surfaces, which directly contact the body of the medicine bottle. The abutment blocks 13 are made of silicone, thus possessing elasticity and deformable to accommodate the diameter difference between the ampoule 6 and the vial 7, thereby simultaneously and securely clamping the ampoule 6 and the vial 7 in one action. In other embodiments, the abutment blocks 13 may also be made of other elastic materials, such as rubber.

[0045] Reference Figure 6 The mounting base 5111 is inclined relative to the vertical direction, which makes the bottom of the placement groove 5111a also inclined. Therefore, the ampoule 6 or vial 7 placed in the placement groove 5111a is also inclined. The inclined bottom of the groove makes the medicine bottle naturally tilted after placement. On the one hand, when drawing liquid, the tilt can make the liquid in the bottle gather at the lowest point on one side, making it easier for the infusion needle to draw out the medicine completely, reducing residue and improving the utilization rate of the medicine. On the other hand, when mixing the liquid, the tilted bottle body also facilitates the liquid to be injected along the bottle wall, reducing impact and the generation of air bubbles.

[0046] Reference Figure 7 and Figure 8 The infusion mechanism 3 includes a first infusion assembly 31 and a second infusion assembly 32. The first infusion assembly 31 is used to transfer the liquid medicine in the ampoule 6 to the vial containing powder 7. The first infusion assembly 31 includes a peristaltic pump 311, a tubing 312, a first infusion needle 313, and a storage box 314. The peristaltic pump 311 includes a motor and a pump head. The motor provides power, and the pump head has a mechanical structure inside for fixing the tubing 312 and realizing the squeezing action. The rollers inside the pump head will roll sequentially on the elastic tubing 312 under the drive of the motor. After the rollers roll, the squeezed part of the tubing 312 will return to its original shape due to its own elasticity, generating negative pressure. This negative pressure will draw fluid into the tubing 312 from the inlet end. As the rollers continue to rotate, the fluid will be pushed forward sequentially and stably delivered from the inlet end to the outlet end. The first infusion needle 313 is fixedly connected to the first end of the tubing 312. The first infusion needle 313 is held by the end of a robotic arm (not shown in the figure, but may be an external cooperating device) of the aspiration station 11. The second end of the tubing 312 is inserted into the storage box 314, which is used to temporarily store the medicine.

[0047] The operation of the first infusion assembly 31 is as follows: When the support 22 carrying the medicine bottle moves to the aspiration station 11 and stops, the robotic arm controls the first infusion needle 313 to move, inserting the needle tip into the ampoule 6; the peristaltic pump 311 starts, drawing the medicine solution from the ampoule 6 through the tubing 312 and temporarily storing it in the storage box 314. Subsequently, the robotic arm removes the needle tip of the first infusion needle 313 from the ampoule 6 and inserts it into the vial 7. The peristaltic pump 311 reverses, injecting the temporarily stored medicine solution in the storage box 314 into the vial 7, mixing it with the powder in the vial 7.

[0048] Next, the shaking mechanism 4 drives the mounting base 5111 to shake, thereby fully mixing the liquid and powder in the vial 7. After mixing, the second infusion assembly 32 performs the final infusion operation.

[0049] Reference Figure 7 The second infusion assembly 32 includes a second power telescopic member 321, an infusion tube 322, a second infusion needle 323, and a connector 324. The second power telescopic member 321 is an electric push rod, and its fixed end is fixedly mounted on the top wall of the base 1; the second power telescopic member 321 is arranged along the inclined direction of the support plate 5212. The second infusion needle 323 is arranged along the length direction of the second power telescopic member 321, and is connected to the movable end of the second power telescopic member 321. Therefore, the second power telescopic member 321 can drive the second infusion needle 323 to move back and forth along its own length direction, inserting or withdrawing the second infusion needle 323 into or from the infusion bag 8. The first end of the infusion tube 322 is fixedly connected to the second infusion needle 323, and the second end of the infusion tube 322 is connected to the connector 324. The connector 324 can also be connected to the first infusion needle 313 simultaneously. In other embodiments, connector 324 can be replaced with a tubular structure for temporarily storing the medication. The medication can be transferred simply by inserting the second ends of the first infusion needle 313 and the infusion tube 322 into this tubular structure.

[0050] The second infusion assembly 32 operates as follows: After the liquid and powder in the vial 7 are thoroughly mixed, the robotic arm drives the first infusion needle 313 to move and insert its tip into the vial 7. The peristaltic pump 311 is activated, drawing out the mixed medication from the vial 7 and temporarily storing it in the storage box 314. Simultaneously, the second power telescopic component 321 is activated, driving the second infusion needle 323 to move precisely upwards at an angle, piercing the medication inlet of the infusion bag 8 fixed on the placement rack 521. Subsequently, the robotic arm removes the tip of the first infusion needle 313 from the vial 7 and inserts it into the connector 324. The peristaltic pump 311 reverses direction, and the medication in the temporary storage box flows sequentially through the tubing 312, the first infusion needle 313, the connector 324, the infusion tube 322, and the second infusion needle 323, before being injected into the infusion bag 8 through the second infusion needle 323. After the injection process is completed, the second power telescopic component 321 pulls the second infusion needle 323 out of the infusion bag 8.

[0051] The infusion mechanism 3 is provided in three sets and is evenly spaced along the length of the base 1. The outer side of the base 1 can cooperate with the three sets of infusion mechanisms 3 through the three robotic arms respectively, so as to carry out the drug preparation process of three stations at the same time, which can further improve work efficiency.

[0052] Reference Figure 9 The rocking mechanism 4 includes a mounting plate 41, a rocking plate 42, a driving gear 43, a driven gear 44, an eccentric shaft 45, and a power assembly 46. The mounting plate 41 is fixedly connected to the first slide table 221. The driving gear 43 and the driven gear 44 are both located above the mounting plate 41 and at the same height. Four driven gears 44 are arranged in a circular array and are rotatably connected to the mounting plate 41 via a rotating shaft. A bearing connects the rotating shaft and the mounting plate 41. All four driven gears 44 mesh with the driving gear 43. The power assembly 46 drives the driving gear 43 to rotate, causing the four driven gears 44 to rotate synchronously.

[0053] Four eccentric shafts 45 are provided, each corresponding to one of the four driven gears 44. Each eccentric shaft 45 is eccentrically fixed to its corresponding driven gear 44. The axes of the eccentric shafts 45 and the axes of the driven gears 44 are spaced apart, and the distance between the axis of each eccentric shaft 45 and the axis of the corresponding driven gear 44 is the same. The eccentric shafts 45 are located above the driven gears 44, and their top ends are fixedly connected to the bottom wall of the rocking plate 42. A support plate 15 is bolted to the top wall of the rocking plate 42, and the support plate 15 is inclined. The mounting base 5111 is fixedly connected to the top wall of the support plate 15, and therefore the mounting base 5111 is also inclined. Therefore, when the driven gear 44 rotates, it can drive the eccentric shaft 45 to rotate. The eccentric shaft 45 drives the rocking plate 42 to move along a circular track. The rocking plate 42 drives the mounting base 5111 and the vial 7 to shake through the support plate 15, thereby accelerating the mixing of the liquid medicine and powder in the vial 7.

[0054] Reference Figure 7 and Figure 9 The power assembly 46 includes a rotating power component 461, a connecting frame 462, a connecting shaft 463, and a connecting block 464. The rotating power component 461 is a motor, which is fixedly connected to the top wall of the base 1, and its output shaft faces vertically upward. The connecting frame 462 is fixedly connected to the top wall of the rotating power component 461. The connecting shaft 463 is coaxially fixedly connected to the bottom end of the drive gear 43, and the bottom end of the connecting shaft 463 protrudes from the bottom wall of the mounting plate 41. The connecting block 464 is fixedly connected to the bottom end of the connecting shaft 463 and is a rectangular block. The connecting frame 462 includes a base plate 4621 and side plates 4622 fixedly connected to both ends of the base plate 4621, with the side plates 4622 positioned above the base plate 4621. The base plate 4621 is horizontally positioned, while the side plates 4622 are vertically positioned, with the two side plates 4622 arranged in parallel at intervals. The distance between the two side plates 4622 is slightly larger than the width of the connecting block 464, allowing the connecting block 464 to slide horizontally and insert between the two side plates 4622 as the conveyor belt 21 rotates. Chamfers are provided at all four corners of the connecting block 464, thus serving as guides and allowing the connecting block 464 to smoothly insert between the two side plates 4622 during sliding. Therefore, when the rotating power component 461 drives the connecting frame 462 to rotate, the connecting frame 462 can drive the connecting block 464 to rotate, which in turn drives the connecting shaft 463 and the drive gear 43 to rotate, thereby driving the drive gear 43.

[0055] Among them, the power assembly 46 is provided in three sets, which correspond to the three sets of infusion mechanisms 3 respectively; each power assembly 46 is used to drive the drive gear 43 which is in the corresponding position to the infusion mechanism 3 to rotate.

[0056] Reference Figure 9Furthermore, a pull rod 421 is fixedly connected to the bottom wall of the rocking plate 42, and a connecting post 411 is fixedly connected to the mounting plate 41. A second elastic element 4211 is fixedly connected between the pull rod 421 and the connecting post 411. The second elastic element 4211 is a tension spring. Under normal conditions, the second elastic element 4211 is at its original length, and the connecting block 464 is in a state where it can be smoothly inserted into the connecting frame 462. When the rotating power component 461 is working, the rocking plate 42 shakes, and the end of the second elastic element 4211 can move together with the pull rod 421, and the second elastic element 4211 can deform accordingly. When the output shaft of the rotating power component 461 stops rotating, the shaking process of the rocking plate 42 is completed, so the second elastic element 4211 can move the pull rod 421 to the initial position, completing the reset process. At this time, the second elastic element 4211 can restrict the movement of the pull rod 421, thereby restricting the movement of the shaking plate 42. This prevents the shaking plate 42 from accidentally shaking after the output shaft of the rotating power component 461 stops rotating, thus ensuring the smooth progress of the subsequent liquid transfer process. Because of the pull rod 421 and the second elastic element 4211, even if the rotating power component 461 uses a motor whose output shaft does not have self-locking capability, the stability of the shaking plate 42 during the liquid transfer process can be guaranteed, further reducing equipment costs.

[0057] Reference Figure 1 The base 1 is also fixedly installed with a vertically arranged feed pipe 16. There are three feed pipes 16 arranged at intervals. The top and bottom of the feed pipe 16 are open. After the infusion bag 8 is taken out after the drug is added, it can be moved to the top of the feed pipe 16. Then the infusion bag 8 can enter the feed pipe 16 and slide down the feed pipe 16 to the subsequent work station.

[0058] The implementation principle of Example 1 is as follows: The conveyor belt 21 operates continuously. At the medicine bag loading station 9, the infusion bag 8 is loaded into the placement rack 521 by the loading mechanism, and the four corners of the infusion bag 8 are pressed by the limiting spring 522 to fix the infusion bag 8 on the placement rack 521. Then the infusion bag 8 moves together with the operation of the conveyor belt 21. When it moves to the medicine bottle loading station 10, the first power telescopic member 5115 of the loading station pushes a clamp 512 outward, thereby driving the two clamps 512 away from each other. Then, the broken ampoule 6 and the opened vial 7 are moved by the loading mechanism into the placement groove 5111a on the mounting base 5111. Then the piston rod of the first power telescopic member 5115 retracts, and the first elastic member 5114 drives the two clamps 512 to move closer to each other, clamping and fixing the ampoule 6 and vial 7. Next, the placement rack 521 containing the infusion bag 8 and the mounting base 5111 containing the ampoule 6 and the vial 7 move together with the operation of the conveyor belt 21. When it moves to the aspiration station 11, the conveyor belt 21 stops running.

[0059] Then, the first infusion assembly 31 transfers the medication. The robotic arm at the aspiration station 11 controls the movement of the first infusion needle 313, inserting the needle tip into the ampoule 6; the peristaltic pump 311 starts, drawing the medication from the ampoule 6 through the tubing 312 and temporarily storing it in the storage box 314. Subsequently, the robotic arm removes the needle tip of the first infusion needle 313 from the ampoule 6 and inserts it into the vial 7. The peristaltic pump 311 reverses, injecting the temporarily stored medication from the storage box 314 into the vial 7, mixing it with the powder in the vial 7; the robotic arm then withdraws the needle tip of the first infusion needle 313 from the vial 7. Next, the shaking mechanism 4 drives the mounting base 5111 to shake, thereby fully mixing the medication and powder in the vial 7. After mixing, the second infusion assembly 32 performs the final infusion operation.

[0060] The robotic arm moves the first infusion needle 313, inserting its tip into the vial 7. The peristaltic pump 311 activates, drawing out the mixed medication from the vial 7 and temporarily storing it in the storage box 314. Simultaneously, the second power telescopic component 321 activates, driving the second infusion needle 323 to move precisely upwards at an angle, piercing the medication inlet of the infusion bag 8 fixed on the placement rack 521. The robotic arm then removes the tip of the first infusion needle 313 from the vial 7 and inserts it into the connector 324. The peristaltic pump 311 reverses, allowing the medication in the temporary storage box to flow through the connector 324 into the second infusion needle 323, and then into the infusion bag 8. After injection, the second power telescopic component 321 withdraws the second infusion needle 323 from the infusion bag 8, completing the medication dispensing process.

[0061] Next, the conveyor belt 21 continues to operate, transferring, mixing, and injecting the liquid medicine on the next support 22. Simultaneously, the infusion bag 8, having completed the dosing process, moves to the unloading station 12. At this point, the unloading mechanism removes the infusion bag 8 and moves it into the unloading pipe 16, allowing it to be conveyed downwards along the pipe. The drive unit 511 drives the two clamping plates 512 to slide in opposite directions, and then the ampoules 6 and vials 7 are removed from the mounting base 5111. This ultimately automates the drug preparation process, eliminating the need for material transfer between different stations, thus achieving efficient, stable, and sterile automated drug preparation.

[0062] Example 2 The difference between this embodiment and Embodiment 1 is that, in order to further improve the reliability of clamping, both clamping plates 512 have clearance grooves on their adjacent sides. The number of clearance grooves is the same as the number of abutment blocks 13, and each clearance groove corresponds to one abutment block 13. A mounting block is slidably connected in the clearance groove, and the abutment block 13 is snapped and fixed to the end of the corresponding mounting block. A spring is fixedly connected between the mounting block and the inner wall of the clearance groove, and the spring is in a compressed state. Therefore, when the radial dimension difference between the ampoule 6 and the vial 7 is too large, making the elastic deformation of the abutment block 13 insufficient to meet the clamping requirements, the abutment block 13 can slide towards the side closer to the inner wall of the clearance groove, so that both sizes of bottles can be clamped simultaneously, thus helping to improve the applicability of the device.

[0063] The above are optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
