Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a quantitative drug dosing device for pharmaceutical preparation. Background Technology

[0002] In pharmaceutical laboratory research, whether it's screening active drug components, developing new dosage forms, or studying pharmacokinetics, accurate drug concentrations are essential. For example, in cell or animal experiments, even small deviations in drug dosage can lead to significant differences in experimental results. Therefore, quantitative dosing devices are needed to ensure the accuracy of each dosing, thereby improving the reliability and scientific validity of experimental data.

[0003] In practical use, during long-term use, the springs in pharmaceutical dispensing devices are usually used to provide a buffering effect. If the springs are not adjusted and their elastic coefficient is fixed, they can only provide a single buffering effect. For example, when the device is subjected to impact forces of different intensities, springs with a fixed elastic coefficient may not be able to effectively buffer larger impacts, leading to damage to internal components of the device. During the dispensing process, the input speed and weight of raw materials may vary, and fixed spring buffers cannot adapt to these changes, affecting the stability of the device.

By tightening the nut and the threaded connection of the positioning column, the positioning column can be fixed while also allowing for a certain degree of adjustment. If the device becomes slightly loose due to vibration or other reasons after long-term operation, the positioning column can be firmly fixed to the top of the first support block by tightening the nut again, restoring the stability of the structure and avoiding component displacement and functional abnormalities caused by loosening.

[0005] To achieve the above objectives, a quantitative dosing device for pharmaceutical preparation is provided, comprising: an L-shaped fixing block; a first support block fixedly connected to the front side of the L-shaped fixing block; a first fixing block fixedly connected to the bottom end of the first support block; first positioning slots formed on both the front and rear sides of the first fixing block; a positioning post slidably connected inside the first positioning slot, extending to the top end of the first support block; a fastening nut threadedly connected to the circumferential surface of the positioning post, the fastening nut abutting against the top end of the first support block; a first spring sleeved on the circumferential surface of the positioning post; the bottom end of the first spring abutting against a limiting post, the top end of the limiting post being fixedly connected to the bottom end of the positioning post; a contact block abutting against the top end of the first spring, the contact block slidably connected to the circumferential surface of the positioning post; a fixing post fixedly connected to the bottom end of the contact block; and a connecting block fixedly connected to the bottom end of the fixing post.

[0026] Working principle: Before using the quantitative dosing device, the laboratory should be kept clean and tidy for half an hour. Then, after starting the hydraulic pump 9, the power generated is transmitted to the hydraulic rod 10 through the output end, causing the hydraulic rod 10 to extend and retract. Since the front end of the hydraulic rod 10 is fixedly connected to the sieve plate 24, the sieve plate 24 slides back and forth in the limiting groove 27 of the limiting block 26 under the drive of the hydraulic rod 10. At this time, the raw material in the feed box 3 slides on the sieve plate 24, and the raw material smoothly passes through the sieve hole 25 and falls to the bottom. During this process, The parameters of the hydraulic pump 9 are adjusted using the control box 8, such as changing the extension and retraction speed and rebound force of the hydraulic rod 10, thereby improving the feeding effect and ensuring the weight and efficiency of the feed. The screened raw materials flow out from the outlet of the feed box 3 and then move to the dispensing frame 6 through the protective pipe 5. During this process, the control box 8 plays a crucial role based on the preset dispensing parameters. It precisely controls the weight of the raw materials and drives the hydraulic pump 9 to ensure the sliding accuracy of the sieve plate 24. The prepared medicine is then collected in the dispensing frame 6, thus completing the dispensing process. The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of this utility model.
