Abstract

A guide wire insertion device for a catheter includes a needle protion provided with a hollow portion, the needle portion having a needle mounted on a front end; a valve mounted in the hollow portion of the needle portion to control flow of blood, a cap portion mounted on a rear end of the hollow portion of the needle portion to fix the valve means in the needle portion, and a syringe for absorbing the blood through the needle portion by penetrating the valve means.

Description

Invention field [0001] The present invention relates to a guide wire insertion device for a catheter, in particular to a guide wire insertion device with a check valve that prevents blood from gushing through a needle inserted into the body. Background technique [0002] Generally speaking, a medical catheter is a hollow tube inserted into a cavity in the body, used for diagnostic purposes, medical injection or expansion of a contracted channel, or treatment purposes including infusion, injection of drugs, and expansion of constricted convulsions. Such catheters are used to treat diseases related to internal tissues such as the heart, duodenum, and others. In particular, catheters are often used to treat diseases of blood vessels, such as arteries and veins. [0003] The catheter can be inserted into the body through a surgical cut down technique or a femoral artery puncture technique (Seldinger technique). In the transfemoral artery puncture technique, the catheter can be insert...
