It can be pasted on the affected area for a long time. It is mainly used to treat boils, swelling and pain. Plaster works through the skin. Plaster therapy is one of the commonly used external treatment methods in clinical Chinese medicine. It follows the principle of Chinese medicine differentiation and treatment and the efficacy, main treatment and meridian of Chinese medicine, fully mobilizes the effectiveness of drugs to coordinate with each other, and forms a compound of multiple drugs to exert the good effect of drugs. In the process of plaster processing, the boiled plaster needs to be filtered to filter out the drug residue to ensure the quality of the plaster.

[0003] However, in the working process of the existing drug residue filter, the existing filter is often unable to effectively perform pre-treatment. This causes the large volume of drug residue to easily clog the filter, affecting the filtering efficiency, and may even interrupt the filtering process. Secondly, in the filtering process, the unfiltered drug solution is often introduced into the filtering chamber after the filtering is completed. This sequence leads to a long filtering time and affects the working efficiency.

[0004] Therefore, it is necessary to provide a kind of plaster processing medicine residue filter to solve the above-mentioned technical problems. Utility Model Content
