PART FOR SLIPPING ON OF A CATHETER TUBE ON A GUIDE, ASSEMBLY COMPRISING SAME AND USE FOR FIXING A CENTRAL VENOUS CATHETER TUBE USING THE SELDINGER TECHNIQUE

摘要

Assembly comprising a catheter tube (2) and a workpiece (5) to facilitate threading of this tube on a guide (3), wherein the catheter (2) one end of tapered threaded tube (1), constituting this piece a tunnel formed internally to determine first and second cones of step (6, 7) which are opposite at their vertices, which communicate with each other and which respectively open into one and the other (8, 9) of the two ends of the tunnel, being the first cone (6) suitable for receiving the tapered end of the catheter until the end is applied against the vertex of this cone, and wherein the second cone (7) such that the guide easily can be inserted therein and guided by the wall of this cone in the direction of the apex of the cone, said creation suitable to allow lateral separation of the part of the catheter tube, characterized in that the first cone (6) fits inside the outer shape of the end of the catheter tube to the piece can be held frictionally on this point, because the two cones communicate via an opening corresponding to the opening (12) of the tapered end of the catheter tube, because the piece has a side flap gripping (14) and a longitudinal slot (13) located on the opposite side of the fin, and that the piece is sufficiently flexible so that the catheter tube can be separated from the workpiece after threading of this tube on the guide step by forcing the tube through said slit whose lips are separated because of the flexibility of the piece.
