Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a filtering device for polypeptide drugs. Background Art

[0002] With the maturity of biotechnology and peptide synthesis technology, more and more peptide drugs are being developed and applied in clinical practice. Due to their wide indications, high safety and significant efficacy, peptide drugs are currently widely used in the prevention, diagnosis and treatment of diseases such as tumors, hepatitis, diabetes, and AIDS, and have broad development prospects. Peptides are a class of compounds formed by multiple amino acids connected by peptide bonds. When manufacturing and producing drugs, a filter device is required to filter the inside of the drug, which can prevent other substances from entering the inside of the drug and prevent the drug from being wasted. Although the current filter device is equipped with a filter plate to prevent the drug bag from entering the barrel when in use, the drug bag covering the filter plate is easy to block the filter hole, thereby affecting the filtration speed of the drug. In addition, the current filter device for peptide drugs has a poor filtration effect, and it is inconvenient to clean the barrel wall and the filter screen after filtration. The drug residue is easy to stick to the barrel wall. Therefore, we have introduced a new filter device for peptide drugs. Utility Model Content
