Description
Technical Field
[0001] The utility model relates to a filtering mechanism for injection liquid preparation, belonging to the technical field of injection liquid preparation equipment. Background Art
[0002] Injections refer to sterile solutions made of drugs for injection into the body, as well as sterile powders or concentrated solutions for preparation into solutions or suspensions before clinical use. Injections act quickly and reliably, are not affected by pH, enzymes, food, etc., have no first-pass effect, and can exert systemic or localized effects. They are suitable for patients who are not suitable for oral medications or cannot take oral medications. However, the research and production process of injections is complicated, with poor safety and body adaptability and high cost. During the production process of injection preparation, the raw materials need to be filtered.
[0003] According to the announcement number CN216988594U, a filtering device for injection liquid preparation is disclosed. The motor of the utility model squeezes the connecting rod through the eccentric wheel, and the connecting rod drives the connecting block to move upward through the vertical rod. The connecting block drives the first circular block to move upward through the second circular block. The first circular block compresses the spring through the filter cartridge. The continuous operation of the motor can drive the filter cartridge to move up and down in a cycle, so that the filter cartridge can filter the material. The utility model does not require manual hand-held sieve plates to filter the material, which improves the effect of removing impurities in the material and the efficiency of screening and filtration. When the above device is in use, although the filter cartridge can move up and down, the distance between the filter cartridge and the collection box changes all the time, which easily causes the material to fall out of the collection box. In addition, the above device needs to loosen and tighten the bolts, which makes loading more inconvenient. Utility Model Content
