CATHETER DEVICE FOR MEDICAL TREATMENT

摘要

PURPOSE: A medical catheter tool is provided to prevent the body fluid from being flown out of the catheter tool and reduce risks of contamination and infections. CONSTITUTION: A medical catheter tool comprises a hub(100), a water-tightening valve(200), a pad(300) and a needle unit(500). The hub is formed as the both end part are opened and has a hollow inside. In the front-end of the hub, a catheter tube is combined. The water-tightening valve is prepared in the other end of the hub in order to be water-tightened. A hole is pierced in case of the penetration by the needle unit. The hole is closed by self-elasticity in case the needle unit is removed. The pad is installed in an end part of the hub which faces towards the catheter tube.
