Description

Technical Field

[0001] This application relates to the field of medical mechanical devices, and in particular to automatic ampoule dispensers. Background Technology

[0002] An ampoule is a heat-sealed rigid glass container commonly used to store injectable drugs, vaccines, serums, etc.; it is a transliteration of the Latin word *ampulla*. Common types include straight-necked and curved-necked ampoules. The capacity is generally 1–25 ml. It is commonly used for injectable solutions and also for packaging oral solutions.

[0003] In clinical practice, when nurses manually open ampoules to prepare intravenous solutions, they typically open the ampoule, use a syringe to extract the liquid, and then inject it into the infusion bottle for convenient patient administration. However, this process is often arduous due to the large number and variety of ampoules, and nurses frequently develop occupational diseases such as tenosynovitis from the strain. Furthermore, errors are prone to occur when preparing large quantities of medications. To reduce nurses' workload, decrease the error rate of manual solution preparation, and improve the accuracy of solution preparation, a fully automated ampoule opener and dispensing device needs to be developed. Summary of the Invention

[0004] To reduce nurses' workload, decrease the error rate of manual solution preparation, and improve the accuracy of solution preparation, this application provides an automatic ampoule opener and solution dispenser.

[0005] The automatic ampoule opener and dispensing device provided in this application adopts the following technical solution: The machine includes a frame, which consists of a storage section, a picking section, a conveying section, a feeding section, and a discharging section. The storage section consists of multiple conveyor seats, which are used to store and convey ampoules. The material handling unit consists of at least one loading robotic arm, which is used to place different types of ampoules onto the conveying unit. The conveying unit includes at least one conveyor belt and multiple fixing seats on the conveyor belt for fixing ampoules; The feeding section includes a feeding claw mounted on the frame, the end of the feeding claw being provided with a fixing sleeve for fitting an ampoule, and a striking rod for striking the ampoule being rotatably connected to the feeding claw. The dispensing section includes a feeding seat for providing syringes and a bottle feeding seat for providing infusion bottles. The frame is equipped with a needle-retrieving robotic arm for picking up syringes. The needle-retrieving robotic arm picks up the syringes, extracts the drug from the ampoules, and then injects the drug into the infusion bottles. The side wall of the frame is provided with a bottle-retrieving port for easy removal of the infusion bottles. The frame is also equipped with a labeling machine, which is used to affix QR codes to the infusion bottles after the medication has been prepared.

[0006] By adopting the above technical solution, during use, various ampoules are placed on multiple conveyor seats. According to the doctor's prescription, the loading robotic arm moves the different ampoules from the conveyor seats to the fixed seats. A fixing sleeve is then placed on the ampoule to stabilize it. A tapping rod is then used to pry open the top of the ampoule, thus opening it. After opening, the ampoule is conveyed to the dispensing section by a conveyor belt. A needle-retrieving robotic arm retrieves the needle and inserts it into the ampoule to draw out the medication, which is then injected into the infusion bottle. Finally, after the injection is completed, a labeling machine affixes a QR code label to the surface of the infusion bottle, reducing the possibility of bottle mix-ups and improving medication safety. Finally, the doctor removes the infusion bottle from the dispensing port for subsequent injection. This design can greatly reduce the number of ampoules that need to be opened, reduce the workload of medical staff, and improve their work comfort.

[0007] Preferably, the conveying seat has a conveying cavity for storing and conveying ampoules. The bottom of the conveying cavity is inclined downward along the side close to the conveying and feeding robot arm. The bottom of the conveying cavity near the feeding robot arm has a buffer arc surface. The buffer arc surface is inclined upward along the side close to the feeding robot arm. The buffer arc surface is used to raise the height of the ampoules.

[0008] By adopting the above technical solution, during use, medical staff can replenish the corresponding ampoules into the corresponding conveyor seat according to the amount of ampoules needed. After the ampoules are placed in the conveying chamber, their gravity will push them upward along the buffer arc surface. This not only increases the height of the ampoules, making it easier for the loading robot arm to pick them up, but also limits the position of the ampoules, reducing the pressure of the ampoules' gravity on the end of the ampoules and reducing the occurrence of damage to the ampoules.

[0009] Preferably, the fixing base has a fixing groove, the bottom of the fixing groove is provided with a vacuum suction cup, and the frame is provided with a vacuum motor connected to the vacuum suction cup. The vacuum motor acts on the vacuum suction cup to fix the ampoule.

[0010] By adopting the above technical solution, a vacuum effect can be achieved through a vacuum motor, which allows the ampoule to be more stably fixed on the mounting base, reducing shaking during ampoule transportation and improving the stability of ampoule fixation.

[0011] Preferably, a buffer ring is rotatably provided on the inner wall of the fixed sleeve, the inner diameter of the buffer ring gradually increases along the direction close to the fixed seat, the feeding claw moves towards the fixed seat and presses the ampoule, and a positioning block is provided on the side of the buffer ring close to the fixed seat, the positioning block abuts against the fixed seat to lock the buffer ring.

[0012] By adopting the above technical solution, the buffer ring sleeve can more reliably fix the ampoule, providing a stable base for subsequent tapping of the ampoule and improving its stability. Furthermore, the rotating design makes it easier for the buffer ring sleeve and the ampoule to be inserted and mated, reducing the possibility of misalignment between the buffer ring sleeve and the ampoule or excessive pressure on the ampoule during the movement of the feeding claw, which could damage the ampoule. Finally, after the buffer ring sleeve is in place, it automatically locks under the action of the positioning block, improving the stability of the ampoule fixation.

[0013] Preferably, a grinding seat is provided on the side of the fixed sleeve away from the fixed base, a grinding disc is telescopically connected inside the grinding seat, and a clamping member is provided inside the grinding seat for driving the grinding disc to abut against the ampoule. A lifting seat is provided at the end of the feeding claw near the frame, the lifting seat is slidably connected to the frame, and a grinding drive member is provided on the lifting seat for driving the feeding claw to rotate around the ampoule.

[0014] By adopting the above technical solution, the grinding drive drives the grinding claw to rotate, which in turn drives the grinding disc to rotate along the outer wall of the ampoule, causing scratches on the surface of the ampoule. This makes it easier to tap the ampoule afterward and improves the ease of opening the ampoule.

[0015] Preferably, the feeding claw is provided with a rotating shaft, the striking rod is rotatably connected to the rotating shaft, the rotating shaft is equipped with a feeding motor, the end of the striking rod near the ampoule is provided with a striking plate, the cross-section of the striking plate gradually decreases along the striking rod towards the ampoule; the end of the striking rod away from the striking plate is provided with a counterweight.

[0016] By adopting the above technical solution, the feeding motor drives the striking rod to break the ampoule, and the addition of a counterweight allows the striking rod to break the ampoule more stably, improving the ease of breaking the ampoule. Preferably, the feeding claw is provided with a pressure seat, and the pressure seat has a pressure groove that is inserted and engaged with the striking rod. A pressure member is provided in the pressure groove, which is used to increase the initial kinetic energy of the striking rod. A locking block is provided on the inner wall of the pressure groove, which is used to lock the striking rod. When the striking rod is in use, the feeding motor applies pressure to the striking rod, so that the striking rod has a certain kinetic energy. When the kinetic energy reaches a certain level, the striking rod overcomes the locking of the locking block and rotates towards the ampoule.

[0017] By adopting the above technical solution, the initial kinetic energy of the striking rod can be made more sufficient through the driving of the pressure component and the feeding motor, so that the striking rod can turn towards the ampoule at a faster speed, making the striking of the ampoule smoother and improving the stability of the striking of the ampoule. When the striking rod is recycled, under the action of the feeding motor, the striking rod is directly stuck into the pressure groove under the action of inertia, making the striking rod easy to use later.

[0018] Preferably, the inner wall of the fixing sleeve is provided with a negative pressure ring groove, the opening of the negative pressure ring groove faces the ampoule, and a suction motor is provided on the frame, the negative pressure ring groove is connected to the suction motor.

[0019] By adopting the above technical solution, the debris from grinding and hammering is extracted through the negative pressure ring groove, which greatly reduces the occurrence of debris falling into the ampoule and improves the safety of the medicine in the ampoule.

[0020] Preferably, the end of the needle-retrieving robotic arm away from the frame includes a clamping claw for clamping the needle tube and a pulling claw for pulling the rear end of the needle tube. The needle-retrieving robotic arm is equipped with an infrared sensor for sensing the ampoule opening and the top of the infusion bottle.

[0021] By adopting the above technical solution, the syringe can more accurately draw liquid from the ampoule and the liquid can be more accurately injected into the infusion bottle.

[0022] Preferably, an ultraviolet sterilizer is installed inside the frame.

[0023] By adopting the above technical solutions, the growth of bacteria inside the rack is greatly reduced, and the safety of using the dispensing device is improved.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. During use, various types of ampoules are placed on multiple conveyor belts. According to the doctor's prescription, the loading robotic arm moves the different ampoules from the conveyor belts to the fixed seats. A fixing sleeve is then placed on the ampoule to stabilize it. A tapping rod is used to pry open the top of the ampoule, thus opening it. After opening, the ampoule is conveyed to the dispensing section by the conveyor belt. A needle-retrieving robotic arm retrieves the needle and inserts it into the ampoule to draw out the medication, which is then injected into the infusion bottle. Finally, after the injection is complete, a labeling machine affixes a QR code to the surface of the infusion bottle to reduce the chance of mixing up the bottles and improve medication safety. Finally, the doctor removes the infusion bottle from the dispensing port for subsequent injection. This design can greatly reduce the number of ampoules that need to be opened, reduce the workload of medical staff in opening ampoules, and improve the comfort of medical staff. 2. During use, medical staff can replenish the corresponding ampoules into the corresponding conveyor seat according to the amount of ampoules needed. After the ampoules are placed in the conveyor chamber, their gravity will push them upward along the buffer arc surface. This not only increases the height of the ampoules, making it easier for the loading robot arm to pick them up, but also limits the position of the ampoules, reducing the pressure of the ampoules' gravity on the end of the ampoules and reducing the occurrence of damage to the ampoules. 3. The grinding drive drives the grinding claw to rotate, which in turn drives the grinding disc to rotate along the outer wall of the ampoule, creating scratches on the surface of the ampoule. This makes it easier to tap the ampoule later and improves the ease of opening the ampoule. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0027] This application discloses an automatic ampoule opener and dispensing device.

[0028] Example 1 Reference Figure 1 The automatic ampoule opening and dispensing unit includes a frame 7, which is a long, streamlined assembly line. Along its length, it comprises a storage section 1, a picking section 2, a conveying section 3, a dispensing section 4, and a dispensing section 5. Ampoules are stored in the storage section 1, picked up by the picking section 2 and placed on the conveying section 3. The dispensing section 4 then processes the ampoules, opening them. Finally, the dispensing section 5 draws the liquid from the ampoules into infusion bottles, completing the dispensing process. An ultraviolet sterilizer 6 is installed inside the frame 7.

[0029] The storage section 1 consists of multiple conveyor seats 11, each rectangular in shape, arranged side-by-side for easier retrieval of ampoules. Each conveyor seat 11 has a conveying cavity 12 for storing and conveying ampoules. The conveying cavity 12 is inclined downwards towards the material handling section 2, allowing for smoother ampoule transport. A buffer arc surface 13 is provided near the bottom of the conveying cavity 12, inclined upwards towards the material handling section 2. After being cushioned by the buffer arc surface 13, the ampoules are raised more easily for subsequent retrieval. Furthermore, the conveying cavity 12 not only stores ampoules but also provides the power to move them, improving the convenience of ampoule storage and transportation.

[0030] The material handling unit 2 consists of at least one loading robotic arm 21. This application uses one loading robotic arm 21, but multiple non-standard loading machines can be manufactured according to the needs of hospitals, thereby meeting the needs of hospitals of different sizes. The material handling unit 2 consists of at least one loading robotic arm 21, which is used to place different ampoules onto the conveyor unit 3.

[0031] The conveying unit 3 includes at least one conveyor belt 31 and multiple fixing seats 32 on the conveyor belt 31 for fixing ampoules. This application uses one conveyor belt 31, with one conveyor belt 31 corresponding to one loading robot arm 21. According to the needs of the hospital, additional loading robot arms 21 can be added, which will increase the number of conveyor belts 31 and improve the ampoule processing efficiency. The fixing seat 32 has a fixing groove 33, and a vacuum suction cup 35 is fixed at the bottom of the fixing groove 33. A vacuum motor 34 connected to the vacuum suction cup 35 is fixed on the frame 7. The vacuum motor 34 acts on the vacuum suction cup 35 to fix the ampoule, improving the convenience of ampoule fixing.

[0032] The feeding unit 4 includes a feeding claw 41 mounted on the frame 7. A lifting seat 471 is fixed to one end of the feeding claw 41 near the frame 7. The lifting seat 471 is slidably connected to the frame 7. The sliding direction of the lifting seat 471 is perpendicular to the upper surface of the conveyor belt 31. A positioning drive cylinder 473 is fixed on the frame 7 to drive the lifting seat 471 to slide. The positioning drive cylinder 473 can make the feeding claw 41 move closer to the ampoule more conveniently. The end of the ejector claw 41 is fixed with a retaining sleeve 411 for fitting ampoules. A buffer ring 45 is rotatably connected to the inner wall of the retaining sleeve 411. The buffer ring 45 is made of elastic rubber. The inner diameter of the buffer ring 45 gradually increases towards the fixing seat 32. The ejector claw 41 moves towards the fixing seat 32 and presses the ampoule. A positioning block 451 is integrally formed on the side of the buffer ring 45 near the fixing seat 32. The positioning block 451 abuts against the fixing seat 32. Under the friction between the positioning block 451 and the fixing seat 32, the buffer ring 45 is locked onto the fixing seat 32. A striking rod 431 for striking the ampoule is rotatably connected to the ejector claw 41. The striking rod 431 can make the ampoule break more stably. A collection box 8 is installed inside the frame 7. The collection box 8 is installed at the bottom of the conveyor belt 31. When the fixed seat 32 is conveyed to the bottom, the vacuum suction cup 35 stops adsorbing the ampoule, so that the ampoule can be discharged more conveniently.

[0033] A grinding seat 46 is fixed to the side of the fixed sleeve 411 away from the fixed base 32. A grinding disc 461 is telescopically connected inside the grinding seat 46. A limiting block is fixed on the grinding disc 461 to limit the travel of the grinding disc 461. A limiting groove is opened inside the grinding seat 46 to slide and cooperate with the limiting block. A clamping member 463, which is a spring, is installed inside the grinding seat 46 to drive the grinding disc 461 to abut against the ampoule. A grinding drive member 472, which is a cylinder, is fixed on the lifting seat 471 to drive the material to rotate around the ampoule. By rotating the material claw 41, the grinding disc 461 rubs against the surface of the ampoule, creating scratches on the surface of the ampoule, so that the top of the ampoule can be broken more smoothly.

[0034] The feeding claw 41 has an integrally formed rotating shaft, and the striking rod 431 is rotatably connected to the rotating shaft. The feeding motor 438 is installed on the rotating shaft. The feeding motor 438 drives the striking rod 431 to strike the ampoule, thereby opening the ampoule. A striking plate 432 is fixed to the end of the striking rod 431 near the ampoule. The striking plate 432 has a boss-shaped cross-section, and its cross-section gradually decreases along the striking rod 431 towards the ampoule. A counterweight 435 is fixed to the end of the striking rod 431 away from the striking plate 432. The counterweight 435 can balance the striking rod 431, allowing the feeding motor 438 to strike the ampoule more stably.

[0035] A pressure seat 433 is fixed on the impact claw 41. The pressure seat 433 has a pressure groove 436 that engages with the impact bar. A pressure element 437, which is a spring, is fixed inside the pressure groove 436. The pressure element 437 is used to increase the initial kinetic energy of the impact bar 431. A locking block 434 is fixed on the inner wall of the pressure groove 436. The locking block 434 is in the shape of a boss. The impact bar 431 can be locked in place by the locking block 434. When the impact bar 431 is in use, the impact motor 438 applies pressure to the impact bar 431, giving it a certain kinetic energy. When the kinetic energy reaches a certain level, the impact bar 431 overcomes the locking of the locking block 434 and rotates towards the ampoule. This allows the impact bar 431 to rotate towards the ampoule more quickly, improving the stability of breaking the ampoule.

[0036] The inner wall of the fixing sleeve 411 is provided with a negative pressure ring groove 44, the opening of which faces the ampoule. A suction motor 42 is fixed on the frame 7. The negative pressure ring groove 44 is connected to the suction motor 42. The negative pressure generated by the suction motor 42 in the negative pressure ring groove 44 removes the debris from grinding and hammering, greatly reducing the occurrence of debris falling into the ampoule and improving the safety of the medicine in the ampoule.

[0037] The dispensing section 5 includes a syringe feeder 53 and an infusion bottle feeder 54. A syringe-retrieving robotic arm 51 is fixed to the frame 7. The robotic arm 51 retrieves the syringe, extracts the medication from the ampoule, and then injects the medication into the infusion bottle. The side wall of the frame 7 has a bottle-retrieving port for easy removal of the infusion tablet. The end of the robotic arm 51 away from the frame 7 includes a clamping claw for gripping the syringe and a pulling claw for pulling the rear end of the syringe. An infrared sensor 52 is installed on the robotic arm 51 to sense and position the ampoule. A labeling machine 9 is fixed to the frame 7, attached to one side of the feeder 54. The labeling machine 9 affixes a QR code to the prepared infusion bottle, allowing for more accurate matching of the infusion bottle to the patient.

[0038] The implementation principle of the automatic ampoule opener and dispensing device in this embodiment is as follows: During use, various ampoules are placed in multiple conveyor seats 11. Under the action of the feeding robotic arm 21, the ampoules are placed in the fixing groove 33. The feeding claw 41 locks the buffer ring 45 onto the ampoule, achieving the function of locking the ampoule. The surface of the ampoule is polished by the grinding disc 461, and then the ampoule is broken by the striking rod 431, thereby opening the ampoule. Then, the needle-retrieving robotic arm 51 uses a needle to inject the liquid from the ampoule into the infusion bottle. Finally, the labeling machine 9 affixes a QR code to the infusion bottle, allowing for more accurate matching between the infusion bottle and the patient. This design can significantly reduce the number of ampoules that need to be opened, reducing the workload of medical staff and improving their comfort.

[0039] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
