Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a drug dispensing device for intravenous chemotherapy in oncology. Background Art

[0002] Intra-arterial chemotherapy is a minimally invasive, safe and less painful method of treating tumors. It has the characteristics of no surgery, less trauma, quick recovery and good results. Intra-arterial chemotherapy can combine several of the most effective anti-cancer drugs together, find the tumor's feeding artery through catheter technology, and inject anti-cancer drugs and embolic agents directly into the tumor tissue.

[0003] At present, during the use of the device, some of the drug residues are easily adsorbed on the inner wall of the barrel, resulting in wall hanging. At the same time, although the filter net can prevent the drug residues from sinking to the bottom, there is a lack of a structure that is convenient for disassembling and assembling the filter net. When the mesh of the filter net is blocked by the drug residues, it is not convenient to disassemble and clean the filter net, so there is room for improvement. Summary of the invention
