Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a transradial artery perfusion chemotherapy fixation device. Background Art

[0002] Hepatic artery infusion chemotherapy is an important treatment for liver malignancies. By puncturing the radial artery or femoral artery, a catheter is placed in the target (hepatic) artery for long-term continuous infusion of chemotherapy drugs. Compared with systemic intravenous chemotherapy, it increases local drug concentration and tumor drug uptake rate, and minimizes systemic toxicity. After the radial artery infusion chemotherapy catheter is placed, the patient needs to keep his arm fixed for a long time to prevent arm movement from causing displacement of the catheter in the blood vessel, so as to avoid causing the catheter to detach from the target (hepatic) artery and affect the efficacy of the infusion chemotherapy.
