INTRODUCTION OF CATHETER BY INTRAVENOUS SELF-REMOVABLE VIA.

摘要

A self-retracting introducer (10) for an intravenous catheter, which has: a retraction tube (14 '') having a body part with an opening (50 '') at a rear and a front part (94) that is distally extends from the body part (88), a retraction body (18 '') having a front part (58 '') mounted for a linear movement inside the body part (88) of the retraction tube (14 '') from which a needle (60) extends distally from the front (58 ''), whereby the retraction body (18 '') is self-retracted into the tube of retraction (14 '') during manual separation of a catheter connector (12) from the retraction tube (14 ''), the retraction body (18 '') being able to be installed from the rear of the retraction tube (14 '') and comprising a thrust spring (16) mounted inside the retraction tube (14 ''), in which said thrust spring (16) has a position n compressed to apply a retraction force to the retraction body (18 '') characterized in that the front part (94) of the retraction tube (14 '') comprises a plurality of arms (96) around a conduit between said arms ( 96) leading to body part 88; and the front part (58 '') of the retraction body (18 '') extends forward by said conduit and between said arms (96); and the connector (12) of the catheter is slidably mounted on and retained by friction on the front part (94) of the retraction tube (14 '') to press said arms (96) together, thereby securing said arms ( 96) against the front part (58 '') of said retraction tube (18 ''), keeping the retraction body in position against the compression of the spring (16).
