Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical solution preparation, and in particular to an automatic pharmaceutical solution preparation machine. Background Technology

[0002] Drug preparation refers to mixing drugs and solvents in a certain proportion to prepare a solution suitable for injection. Drug preparation requires the use of a dispensing machine, which is a device used to mix two or more different liquids in a certain proportion.

[0003] A search revealed that Chinese Patent Publication No. CN218609221U discloses an automated drug dispensing device with a vibration structure. A motor drives a cam to rotate, and the cam pushes a slider upward, causing the slider to move upward inside the connecting block. When the cam and the slider are not in contact, the slider moves downward rapidly under the action of a first spring. The slider hits the inner wall of the connecting block, which causes the dispensing head to vibrate and quickly shake off any residual drug solution inside the dispensing head.

[0004] In the above technical solution, a motor is used in conjunction with a cam mechanism, slider, spring, and other structures to vibrate the injection head and prevent drug residue inside. However, when the drug solution is prepared and dispensed, the volume of the injection cup will vary, making it impossible to fix the injection cup and prevent the drug solution from being affected by the external temperature during long-term injection, thus reducing the stability of the solution preparation. Therefore, an automatic drug solution preparation machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an automatic drug solution dispensing machine, which aims to improve the existing technology by not fixing the dispensing cup during dispensing and by not being able to ensure that the drug solution is not affected by the external temperature.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic pharmaceutical solution dispensing machine, comprising a dispensing machine body, a cylinder fixedly connected to the surface of the dispensing machine body, a fixing block fixedly connected to the output end of the cylinder, an injection head provided at the bottom of the fixing block, an injection structure provided on the surface of the dispensing machine body, the injection structure including a placement groove, a weighing device provided inside the placement groove, a telescopic rod fixedly connected to the inner wall of the placement groove, a spring sleeved on the outer wall of the telescopic rod, a fixing plate fixedly connected to the end of the spring, a heat insulation component provided on the surface of the fixing plate, and a fixing component provided inside the placement groove.

[0007] As a further description of the above technical solution:

[0008] The lower surface of the fixing block is provided with an embedding groove, the inner wall of the embedding groove is threaded with a threaded ring, the outer wall of the injection head is fixedly connected with an anti-slip ring, and the outer wall of the injection head is threaded with a collar through a pipe.

[0009] As a further description of the above technical solution:

[0010] The placement slot is formed on the surface of the liquid preparation machine body, and the placement slot is located directly below the liquid injection head. The interior of the fixing plate is hollow.

[0011] As a further description of the above technical solution:

[0012] The insulation component includes a heat-conducting plate, and a connecting pipe is fixedly connected to the inner wall of the fixing plate. The connecting pipe is fixedly connected to a circulating chiller.

[0013] As a further description of the above technical solution:

[0014] The fixing component includes an embedding hole, a fixing magnet is fixedly connected to the inner wall of the placement slot, an attracting magnet is magnetically connected to the top of the fixing magnet, and a support block is fixedly connected to the bottom of the weighing device.

[0015] As a further description of the above technical solution:

[0016] The heat-conducting plate is fixedly connected to the side of the fixed plate away from the spring.

[0017] As a further description of the above technical solution:

[0018] The embedding hole is located inside the placement groove, and the inner wall of the embedding hole is adapted to the outer wall of the support block.

[0019] As a further description of the above technical solution:

[0020] The upper surface of the attracting magnet is fixedly connected to the lower surface of the weighing device.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting a support block to insert into the embedding hole and combining the magnetism of the fixing magnet and the attracting magnet, the weighing device can be fixed in the placement groove. The telescopic rod and the elasticity of the spring can fix the fixing plate to both sides of the injection cup. The circulating chiller injects coolant into the fixing plate and then, through the heat conduction characteristics of the heat conduction plate, keeps the injection cup in a constant cold state, reducing the influence of external temperature on the liquid during long-term injection and ensuring the stability of the liquid preparation.

[0023] 2. In this utility model, the anti-slip ring facilitates gripping and allows for quick assembly and disassembly of the injection head through the cooperation of the threaded ring and the embedded groove. The collar can separate or combine the injection head with the pipeline that transmits the liquid medicine, thereby facilitating the disinfection and cleaning of the inside of the injection head and ensuring the quality and safety of subsequent liquid preparation.

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.

[0032] Reference Figures 1-3This utility model provides an embodiment of an automatic drug solution dispensing machine, comprising a dispensing machine body 1, a cylinder 2 fixedly connected to the surface of the dispensing machine body 1, a fixing block 3 fixedly connected to the output end of the cylinder 2, an injection head 4 provided at the bottom of the fixing block 3, the injection head 4 introducing the drug solution through an external hose, the flow rate of the drug solution being controlled by a valve during injection, an injection structure provided on the surface of the dispensing machine body 1, the injection structure including a placement groove 5 for placing the injection cup, and a weighing device provided inside the placement groove 5. 6. Weighing device 6 weighs the injection cup after liquid injection, so that the operator can intuitively see the amount of liquid injected. The inner wall of the placement tank 5 is fixedly connected to a telescopic rod 7. The outer wall of the telescopic rod 7 is fitted with a spring 8. The end of the spring 8 is fixedly connected to a fixing plate 9. There are two sets of telescopic rods 7 and springs 8. The two sets of telescopic rods 7 and springs 8 are mirror images of each other with the central axis of the placement tank 5 as the axis of symmetry. The number of fixing plates 9 is the same as that of telescopic rods 7. The surface of the fixing plate 9 is provided with a heat insulation component. The inside of the placement tank 5 is provided with a fixing component.

[0033] Reference Figures 3-5 The placement slot 5 is located on the surface of the main body 1 of the liquid dispensing machine, directly below the injection head 4. The interior of the fixing plate 9 is hollow. The insulation component includes a heat-conducting plate 10. A connecting pipe 11 is fixedly connected to the inner wall of the fixing plate 9. The connecting pipe 11 is a three-way pipe and extends into the cavity of the fixing plate 9. A portion of the connecting pipe 11 near the fixing plate 9 is retractable. A circulating chiller 12 is fixedly connected to the connecting pipe 11. The fixing component includes an embedding hole 13. The inner wall of the placement slot 5 is fixedly connected to... A fixed magnet 14 is magnetically connected to the top of the fixed magnet 14, and a holding magnet 15 is magnetically connected to the bottom of the weighing device 6. A support block 16 is fixedly connected to the bottom of the weighing device 6. Four sets of support blocks 16 are arranged in a rectangular array at the bottom of the weighing device 6. The number of embedding holes 13 is equal to the number of support blocks 16. A heat-conducting plate 10 is fixedly connected to the side of the fixed plate 9 away from the spring 8. The embedding hole 13 is located inside the placement groove 5. The inner wall of the embedding hole 13 is adapted to the outer wall of the support block 16. The upper surface of the holding magnet 15 is fixedly connected to the lower surface of the weighing device 6.

[0034] Reference Figure 5 The lower surface of the fixing block 3 is provided with an embedding groove 17. The inner wall of the embedding groove 17 is threaded with a threaded ring 18. The threaded ring 18 is inserted into the embedding groove 17 and can be separated or combined with the injection head 4 by rotating it forward or backward, so as to facilitate its removal for disinfection and cleaning. The outer wall of the injection head 4 is fixedly connected with an anti-slip ring 19. The anti-slip ring 19 is convenient for the operator to hold and apply force to the injection head 4. The outer wall of the injection head 4 is connected with a collar 20 through a pipe thread.

[0035] Working principle: When preparing the medicine solution, the solution is poured into the injection cup through the injection head 4. First, the weighing device 6 is placed inside the placement slot 5, and the support block 16 is inserted into the embedding hole 13. At the same time, the attraction between the fixing magnet 14 and the attracting magnet 15 fixes the weighing device 6. Then, the injection cup is vertically inserted into the injection cup. At this time, the injection cup will compress the telescopic rod 7 and the spring 8. The elasticity of the two allows the two sets of fixing plates 9 to fix the two sides of the injection cup. At the same time, the heat-conducting plate 10 is attached to the surface of the injection cup, and the circulating chiller 12 injects coolant into the interior of the fixing plate 9. The weight of the injection cup is on the weighing device 6. The operator first zeroes the weighing device 6, then uses the injection head 4 to inject the liquid. When the injection head 4 continues to inject liquid, the heat conduction plate 10 can transfer the cold source of the coolant to the surface of the injection cup, keeping the liquid relatively cold and avoiding the influence of the outside temperature on the liquid during long-term injection. After the liquid preparation is completed, the operator holds the anti-slip ring 19 and reverses the injection head 4 until the threaded ring 18 gradually disengages from the inside of the embedded groove 17. Finally, the collar 20 is reversed to gradually separate it from the pipeline, making it easy to quickly remove the injection head 4 for disinfection and cleaning, avoiding residual liquid adhering to the inner wall of the injection head 4, and ensuring the quality and safety of the liquid preparation.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
