Description

Technical Field

[0001] This utility model relates to the field of biomedical technology, specifically to a pharmaceutical preparation dispensing device for biomedical production. Background Technology

[0002] In the field of biopharmaceutical production, drug dispensing is a key step in ensuring drug quality and efficacy. Although traditional drug dispensing equipment has achieved automation to a certain extent, it is still difficult to meet the strict dosage requirements of biopharmaceutical products in terms of controlling the amount of drug dispensed.

[0003] A search revealed a Chinese patent with publication number CN221370573U that discloses a pharmaceutical dispensing device for biopharmaceutical production, relating to the field of biopharmaceutical technology. The device includes an overall structure and an auxiliary structure, with the auxiliary structure located at the bottom sides and front and rear positions of the overall structure. The overall structure includes a base plate, with a housing fixedly connected to the top center of the base plate. A first telescopic rod is fixedly installed at the front and rear positions of the inner top of the housing. In this invention, after the user places the medicine bottle onto the corresponding anti-slip pad, it can be conveyed by a conveyor belt to a position suitable for multiple dispensing heads. Then, through the cooperation of a water pump, the first telescopic rod, a movable plate, the dispensing heads, and rubber hoses, the first telescopic rod drives the dispensing head downwards and inserts it into the medicine bottle, thus completing the dispensing operation, reducing manual intervention, and increasing overall work efficiency.

[0004] In the above technology, although the agent is delivered into the rubber hose by a water pump and then distributed to multiple dispensing heads through the rubber hose to facilitate subsequent dispensing, the accuracy of the agent distribution in the rubber hose is affected by factors such as the inner diameter, length and location of the distribution point, resulting in inconsistent drug dosages flowing out from each dispensing head. In addition, it is difficult to accurately control the dosage of the dispensed agent by using a water pump for delivery.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: Figure 1-7As shown, this utility model provides a pharmaceutical dispensing device for biopharmaceutical production, including a storage tank 1. Three conduits 2 are connected to the bottom of the storage tank 1. One end of each conduit 2 is connected to a piston cylinder 3. A connecting pipe 4 is connected to the bottom of the piston cylinder 3 adjacent to the conduit 2. A nozzle 5 is connected to the bottom of the connecting pipe 4. A rubber stopper 6 is slidably connected inside the piston cylinder 3. A first fixing ring 7 is fixedly connected to one end of the conduit 2 at the storage tank 1. A first blocking block 8 is located below the first fixing ring 7 on the conduit 2, and the first blocking block 8 movably overlaps with the first fixing ring 7. A second fixing ring 9 is fixedly connected to one end of the inner wall of the connecting pipe 4. A second blocking block 10 is located below the second fixing ring 9 on the connecting pipe 4, and the second blocking block 10 movably overlaps with the second fixing ring 9. The conduit 2 is located at the first... A first support frame 11 is fixedly connected below the fixed ring 7. A slide rod 12 is slidably connected to the middle of the first support frame 11. The top of the slide rod 12 is fixedly connected to the first block 8. A first spring 13 is fixedly connected to the top of the first support frame 11. The first spring 13 is fixedly connected to the first block 8. The slide rod 12 is located inside the first spring 13. A limit block 14 is fixedly connected to the bottom of the slide rod 12. A second support frame 15 is fixedly connected below the second fixed ring 9. A telescopic rod 16 is fixedly connected to the top of the second support frame 15. A second block 10 is fixedly connected to the top of the telescopic rod 16. A second spring 17 is fixedly connected to the top of the second support frame 15. The second spring 17 is fixedly connected to the second block 10. The telescopic rod 16 is located inside the second spring 17.

[0029] In this embodiment, during drug dispensing, the drug bottle is first placed below the nozzle 5. Then, the rubber stopper 6 is driven to move upward, creating a negative pressure inside the piston cylinder 3. Under this negative pressure, the first block 8 moves downward. As the first block 8 moves downward, the first spring 13 contracts. At this time, the drug in the storage tank 1 flows into the conduit 2 through the through hole in the middle of the first fixing ring 7, and then into the piston cylinder 3 through the conduit 2. The amount of drug dispensed is controlled by the upward movement distance of the rubber stopper 6. When the piston cylinder 3 contains a set amount of drug, the movement of the rubber stopper 6 is stopped. At this time, the first spring 13 rebounds, pushing the first block 8 upward and contacting the first fixing ring 7, thereby closing the middle of the first fixing ring 7. The through hole is blocked to prevent the medicine in the conduit 2 from flowing back into the medicine storage tank 1, thus ensuring the accuracy of medicine dispensing. Then, the rubber stopper 6 is driven to move downward. At this time, the second block 10 will move downward under the action of hydraulic pressure. The second spring 17 and the telescopic rod 16 will retract. At this time, the medicine in the piston cylinder 3 will flow into the connecting pipe 4 through the through hole in the middle of the second fixed ring 9, and then into the medicine bottle through the nozzle 5 at the bottom of the connecting pipe 4, thus realizing the dispensing of medicine. When the rubber stopper 6 moves to the bottom of the piston cylinder 3, it will stop moving. At this time, the hydraulic pressure in the piston cylinder 3 will disappear. Then the second spring 17 and the telescopic rod 16 will rebound, thereby pushing the second block 10 to move upward, so that the second block 10 blocks the through hole in the middle of the second fixed ring 9.

[0030] A rotating shaft 18 is slidably connected to the center of the top of the medicine storage tank 1. A connecting plate 19 is fixedly connected to the bottom of the rotating shaft 18. Three stirring rods 20 are fixedly connected to the bottom of the connecting plate 19. A top block 21 is fixedly connected to the bottom of the stirring rods 20.

[0031] In this embodiment, during actual use, air may be present in the conduit 2 at the beginning of the dispensing process, which may lead to uncertainty in the dosage of medicine drawn into the piston cylinder 3 and thus affect the accuracy of medicine dispensing. Therefore, it is necessary to expel the air from the conduit 2 at the beginning of medicine dispensing. During operation, the operator first rotates the shaft 18, thereby driving the stirring rod 20 to rotate, so that the top block 21 at the bottom of the stirring rod 20 is directly above the inlet of the conduit 2. Then, the operator presses the shaft 18 to move the stirring rod 20 and the top block 21 downward. When the top block 21 passes through the through hole in the middle of the first fixing ring 7 and contacts the first block 8, the first block 8 will move downward under the pressure of the operator, so that the medicine in the medicine storage tank 1 can flow smoothly into the conduit 2, thereby expelling the air from the conduit 2 and ensuring the accuracy of subsequent medicine dispensing.

[0032] A sleeve 22 is rotatably connected to the top center of the medicine storage tank 1. The sleeve 22 is fitted onto the outer wall of the rotating shaft 18. A spline block 23 is fixedly connected to the inner wall of the sleeve 22. A spline groove 24 is provided on the side wall of the rotating shaft 18. The spline block 23 and the spline groove 24 are slidably connected.

[0033] In this embodiment, the design of the sleeve 22, spline block 23 and spline groove 24 allows the rotating shaft 18 to slide up and down and rotate smoothly.

[0034] A first gear 25 is fixedly connected to the outer wall of the sleeve 22, a motor 26 is fixedly connected to one end of the top of the medicine storage tank 1, and a second gear 27 is fixedly connected to the output end of the motor 26. The first gear 25 and the second gear 27 are meshed and connected.

[0035] In this embodiment, when the medicine in the storage tank 1 is stored for a long time, sedimentation may occur. At this time, the motor 26 drives the second gear 27 to rotate, thereby driving the first gear 25 and the sleeve 22 to rotate. The motor then drives the rotating shaft 18 to rotate, thereby driving the stirring rod 20 to rotate, thereby achieving stirring of the medicine and preventing sedimentation.

[0036] A mounting plate 28 is fixedly connected to the top of the rotating shaft 18, a third spring 29 is fixedly connected to the bottom of the mounting plate 28, the third spring 29 is fixedly connected to the first gear 25, and handles 30 are fixedly connected to both ends of the mounting plate 28.

[0037] In this embodiment, the design of the third spring 29 allows the operator to stop pressing the rotating shaft 18, and the third spring 29 will rebound, thereby driving the rotating shaft 18 and the stirring rod 20 to move upward, so that the stirring rod 20 has more space to stir the medicine. The design of the handle 30 makes it easier for the operator to press the rotating shaft 18. The handle 30 also makes it easier for the operator to observe the angle when rotating the rotating shaft 18, and thus more easily rotate the top block 21 to be directly above the inlet of the conduit 2.

[0038] A cylinder 31 is fixedly connected to one end of the medicine storage tank 1. A fixed plate 32 is fixedly connected to the output end of the cylinder 31. Three connecting rods 33 are fixedly connected to the bottom of the fixed plate 32. A rubber plug 6 is fixedly connected to the bottom of the connecting rods 33. A feed inlet 34 is provided at one end of the top of the medicine storage tank 1. Four support legs 35 are fixedly connected to the bottom of the medicine storage tank 1.

[0039] In this embodiment, the cylinder 31 is designed to drive the rubber plugs 6 to move up and down, and the fixed plate 32 and connecting rod 33 are designed to allow the three rubber plugs 6 to be smoothly fixed at the output end of the cylinder 31.

[0040] Working Principle: During drug dispensing, the drug to be dispensed is first injected into the storage tank 1 through the inlet 34. During the dispensing process, the drug bottle is placed below the nozzle 5. Then, the cylinder 31 drives the fixing plate 32 and connecting rod 33 to move upward, thereby moving the rubber stopper 6 upward. At this time, a negative pressure is generated in the piston cylinder 3. Under the action of the negative pressure, the first block 8 moves downward. When the first block 8 moves downward, the first spring 13 contracts. At this time, the drug in the storage tank 1 flows into the guide tube 2 through the through hole in the middle of the first fixing ring 7, and then into the piston cylinder 3 through the guide tube 2. The amount of drug dispensed is controlled by the upward movement distance of the rubber stopper 6. In addition, when the rubber stopper 6 moves upward, the negative pressure generated in the piston cylinder 3 causes the second block 10 to tightly block the through hole on the second fixing ring 9, thereby preventing outside air from flowing into the piston cylinder 3. This ensures that a negative pressure can be generated smoothly in the piston cylinder 3. When the piston cylinder 3 contains the set amount of drug, the cylinder 31 is closed, and the dispensing process stops. When the rubber stopper 6 moves, the first spring 13 will rebound, pushing the first block 8 upward and contacting the first fixing ring 7, thus blocking the through hole in the middle of the first fixing ring 7. This prevents the medicine in the conduit 2 from flowing back into the medicine storage tank 1, thereby ensuring the accuracy of medicine dispensing. Then, the cylinder 31 drives the fixing plate 32 and the connecting rod 33 to move downward, thereby driving the rubber stopper 6 downward. At this time, the second block 10 will move downward under the action of hydraulic pressure, where the second spring 17 and the telescopic rod 16 will retract. At this time, the medicine in the piston cylinder 3 will flow into the connecting pipe 4 through the through hole in the middle of the second fixing ring 9, and then into the medicine bottle through the nozzle 5 at the bottom of the connecting pipe 4, thus realizing the dispensing of medicine. When the rubber stopper 6 moves to the bottom of the piston cylinder 3, it will stop moving. At this time, the hydraulic pressure in the piston cylinder 3 will disappear, and the second spring 17 and the telescopic rod 16 will rebound, pushing the second block 10 upward, so that the second block 10 blocks the through hole in the middle of the second fixing ring 9.

[0041] Additionally, air may be present in the conduit 2 during the initial dispensing process, leading to uncertainty in the dosage of medicine drawn into the piston cylinder 3 and affecting the accuracy of medicine dispensing. Therefore, the air in the conduit 2 needs to be expelled at the beginning of dispensing. During operation, the operator first grasps the two handles 30 and rotates them, thereby rotating the rotating shaft 18 and the stirring rod 20. This positions the top block 21 at the bottom of the stirring rod 20 directly above the inlet of the conduit 2. Then, the operator presses the handles 30, causing the rotating shaft 18, stirring rod 20, and top block 21 to move downwards. At this time, the third spring 29 will contract. When the top block 21 passes through the through hole in the middle of the first fixing ring 7 and contacts the first block 8, the first block 8 will then be dislodged under the operator's pressure. The handle 30 moves downwards, allowing the medicine in the storage tank 1 to flow smoothly into the conduit 2, thereby expelling the air in the conduit 2 and ensuring the accuracy of subsequent medicine dispensing. After the air in the conduit 2 is emptied, the handle 30 can be released, at which point the third spring 29 will rebound, thereby driving the rotating shaft 18, stirring rod 20, and top block 21 to move upwards, so that the stirring rod 20 has more space to stir the medicine. When the medicine in the storage tank 1 has been stored for a long time, sedimentation may occur. At this time, the motor 26 drives the second gear 27 to rotate, thereby driving the first gear 25 and sleeve 22 to rotate, which in turn drives the rotating shaft 18 to rotate, thereby driving the stirring rod 20 to rotate, thereby achieving stirring of the medicine and preventing sedimentation.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
