Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical research technology, specifically a precise quantitative dispensing device for pharmaceutical experiments. Background Technology

[0002] Pharmaceutical experiments involve developing drug plans based on the hospital's medical, research, and teaching needs and the basic drug list; researching and mastering drug technology and market information; and providing safe, effective, high-quality, and affordable drugs to clinicians. This often requires the timely and accurate dispensing of Chinese and Western medicines according to hospital physician prescriptions, and the planned production of ordinary preparations, sterilized preparations, and traditional Chinese medicine preparations.

[0003] In pharmaceutical experiments, when preparing reagents, it is often necessary to dispense large containers of reagents into different vials according to the formula. When dispensing and filling, it is difficult to control the amount of reagents and they cannot be filled directly. Usually, precise measuring devices such as droppers are needed for transfer, which is time-consuming and labor-intensive. Moreover, only one vial can be filled at a time, which is inefficient and very inconvenient.

[0004] To address this, a refined quantitative drug dispensing device for pharmaceutical experiments is proposed. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a precise quantitative dispensing device for pharmaceutical experiments, comprising a main body 1, as shown in the figure. Figure 1 As shown, the main body 1 is ring-shaped, as... Figure 2 As shown, an annular cavity 2 is coaxially arranged inside the main body 1, allowing the medicine to be injected into the annular cavity 2. The main body 1 is horizontally positioned to ensure that the medicine is evenly stored inside the annular cavity 2. Several suction tubes 3 are vertically arranged through the upper side wall of the annular cavity 2. The suction tubes 3 are evenly distributed in a ring on the annular cavity 2. A suction chamber 4 is arranged inside each suction tube 3. A piston 5 is movably arranged on the inner surface of the suction chamber 4. The bottom of the suction tube 3 is provided with a connection to the annular cavity. The inlet pipe 6 is connected to the annular cavity 2, and the bottom of the suction pipe 3 is connected to the outlet pipe 7 that passes through the annular cavity 2. By controlling the movement of the piston 5, the liquid medicine located inside the annular cavity 2 is drawn into the suction cavity 4 through the inlet pipe 6. The upper surface of the piston 5 is fixedly connected to the connecting rods 8, which are all vertically set. The upper end of the connecting rods 8 is fixedly connected to the same movable plate 9. By controlling the movement of the movable plate 9, the movable plate 9 drives the piston 5 to move synchronously through the connecting rods 8, so that the liquid medicine is drawn into the suction cavity 4 at the same time.

[0020] Specifically, a base 10 is provided at the bottom of the main body 1. The base 10 is a circular plate, and a number of support rods 11 are fixedly connected between the base 10 and the main body 1.

[0021] Specifically, a fixed tube 12 is fixedly connected to the upper surface of the base 10. The fixed tube 12 is coaxially arranged with the base 10. The inner circumferential surface of the fixed tube 12 is provided with an internal thread. A transmission rod 13 is screwed into the inside of the fixed tube 12. The transmission rod 13 passes through the end face of the movable plate 9. Limiting rings 14 are respectively provided on the upper and lower sides of the movable plate 9 on the outer circumferential surface of the transmission rod 13. By rotating the transmission rod 13, the transmission rod 13 moves relative to the fixed tube 12 under the action of the threaded engagement. The transmission rod 13 drives the movable plate 9 to move through the limiting rings 14. The movable plate 9 can drive the piston 5 to move synchronously through the connecting rod 8, so that the suction chamber 4 can synchronously suction the liquid medicine located inside the annular cavity 2.

[0022] Specifically, a support plate 15 is movably disposed between the base 10 and the main body 1. The support plate 15 is a circular plate and is horizontally disposed. A through groove 16 corresponding to the liquid outlet pipe 7 is disposed through the end face of the support plate 15. The through groove 16 is circular. A medicine bottle for receiving liquid can pass through the through groove 16 and be placed at the bottom of the liquid outlet pipe 7, thereby supporting the medicine bottle and preventing it from tipping over.

[0023] Specifically, such as Figure 2 As shown, the limiting ring 14 located on the lower side of the movable plate 9 is movably connected to the transmission rod 13. The outer surface of the transmission rod 13 is fitted with a movable sleeve 17, and the movable sleeve 17 is slidably connected to the transmission rod 13. The movable sleeve 17 can slide up and down along the transmission rod 13, and drive the limiting ring 14 connected to it to slide synchronously. The end face of the movable sleeve 17 is threaded through and screwed with a fastening bolt 18. The fastening bolt 18 extends along the radial direction of the movable sleeve 17. By rotating the transmission rod 13, the movable plate 9 is driven to move upward, and the piston 5 is driven to move through the connecting rod 8. After the medicine is sucked up, in order to improve efficiency, the fastening bolt 18 can be loosened, so that the movable sleeve 17 drives the limiting ring 14 to move downward. Thus, the movable plate 9 can be directly lowered and moved downward, driving the piston 5 to move downward, so that the medicine in the suction cavity 4 is injected into the bottom medicine bottle through the liquid outlet pipe 7.

[0024] Specifically, the inlet pipe 6 and the outlet pipe 7 are respectively fixedly connected with one-way valves. The outlet pipe 7 is located at the lower end of the annular cavity 2. When the piston 5 moves upward, the medicine inside the annular cavity 2 can enter the suction cavity 4 through the inlet pipe 6, while external gas will not enter the suction cavity 4 through the outlet pipe 7. When the piston 5 moves downward, the medicine inside the suction cavity 4 can flow into the medicine bottle through the outlet pipe 7, and will not enter the annular cavity 2 through the inlet pipe 6.

[0025] In use, the medicine is injected into the annular cavity 2. The medicine bottle is placed at the bottom of the outlet pipe 7 through the through groove 16. By rotating the transmission rod 13, the movable plate 9 is moved upward under the action of the threaded engagement. The movable plate 9 drives the piston 5 to move upward through the connecting rod 8. The liquid is sucked into the suction cavity 4 through the inlet pipe 6. Then, the fastening bolt 18 is loosened, the movable sleeve 17 is moved down, and the movable plate 9 is pressed down directly. The medicine is then injected into the medicine bottle through the inlet pipe 6 under the action of the piston 5.
