Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a PICC catheter puncture hemostat. Background Art

[0002] PICC catheterization is the insertion of a central venous catheter through a peripheral vein. PICC catheterization is a safe and effective catheterization technique that is very common in clinical chemotherapy patients. During the operation, a vein puncture is usually performed at the elbow, and the PICC catheter is inserted into the superior vena cava or subclavian vein through an insertion sheath. This facilitates the infusion of chemotherapy drugs, helps protect peripheral veins, and can reduce the stimulation of chemotherapy drugs on blood vessels. After the actual PICC catheterization puncture is completed, a long period of hemostasis is required, usually six to eight hours.

[0003] However, after using the hemostat in the prior art, it is not convenient to replace the hemostatic cotton pad, and repeated use is likely to cause cross infection, thereby aggravating the patient's condition. In addition, the hemostat has a simple structure and poor stability. After the patient moves his hand, the hemostatic cotton pad is easily displaced, affecting the hemostatic effect. For this reason, we propose a PICC catheter puncture hemostat. Utility Model Content
