Title: Intravenous catheters with blood backflow prevention
Inventor: KIM KEUN BAE
IPC: A61M25/06
Filed: 2019-10-25
Abstract: The present invention relates to an intravenous catheter capable of preventing the backflow of blood even when a chamber formed with needles is separated from a hub connected to the blood vessel by a catheter needle after the injection of a drug solution. The present invention comprises: a catheter hub provided with a catheter needle at one end and having the other end opened to have an accommodation space; a chamber having a needle inserted into the accommodation space of the catheter hub and penetrating the catheter needle at one end; and a backflow prevention means accommodated in the catheter hub and preventing the backflow of blood when the chamber is withdrawn from the catheter hub. The backflow prevention means is composed of a soft valve body in close contact with the inner diameter of the accommodation space and a guide inserted into the valve body to prevent the backflow of blood by the valve body and to assemble the needle in place by the guide. The valve body has a backflow prevention structure by means of an opening and closing part protruding forward toward the catheter needle and a cutout part formed in the opening and closing part, and the guide is formed to induce central insertion of the needle, thereby providing the blood backflow prevention structure with a simple structure. When the backflow prevention means is inserted into the catheter hub, a pressure frame is formed to protrude along the outer periphery of the valve body in order to prevent torsion from occurring due to pressure acting on the opening and closing part or the cutout part, so that the pressure frame is in close contact with the inner diameter of the accommodation space of the catheter hub to ensure sealing. By arranging a plurality of pressure frames to be spaced apart, the valve body is inserted into the correct position while maintaining a horizontal state without inclination when the valve body is inserted into the catheter hub so that precise operation is performed.
