Title: IMPROVED SAFETY CATHETER NEEDLE
Abstract:
Safety catheter needle comprising a cannula (11) removably inserted in a catheter (14) and associated with a cannula holder (4), the catheter being associated with a catheter holder (3) attached to said cannula holder (4), the cannula (11) having a distal extremity (11B) capable of sliding within the catheter (14), provision being made for a protection device (8) capable of accommodating the distal extremity (11B) of the cannula (11) after extraction from the catheter (14) and comprising magnetically cooperating bodies (12, 13) capable of immobilising said distal extremity (11B) of the cannula (11) within said protection device (8); said bodies are a first body (13) and a second body (12) which are at least partly magnetised, the second body (12) being located transversely and rotatably within the first body (13), said second body (12) being rotated by magnetic repulsion within said first body (13) when the distal extremity (11B) of the cannula (11) is within the protection device (8) so as to prevent said distal extremity (11B) of the cannula (11) from emerging from said protection device (8).
