Title
(EN) NEEDLE COVER RETENTION
(FR) RÉTENTION DE CAPUCHON D'AIGUILLE
Abstract
(EN)
A catheter assembly (20) may include a catheter adapter (22), which may include a body (24) and a nose (26) extending distally from the body. The nose may be generally cylindrical. A strain relief rib (42) may be disposed on the nose. The strain relief rib (42) may be constructed of a flexible material. The catheter assembly may also include a needle (32) secured within the catheter adapter and extending distally beyond the nose. The catheter assembly may further include a needle cover (3)6, which may be removably coupled to the nose of the catheter adapter. An inner surface of the needle cover may be smooth and may contact the strain relief rib.
(FR)
La présente invention concerne un ensemble cathéter (20) pouvant comprendre un adaptateur de cathéter (22), qui peut comprendre un corps (24) et un nez (26) s'étendant au plan distal du corps. Le nez peut être généralement cylindrique. Une nervure de réduction de contrainte (42) peut être disposée sur le nez. La nervure de réduction de contrainte (42) peut être construite à partir d'un matériau souple. L'ensemble cathéter peut également comprendre une aiguille (32) solidement fixée à l'intérieur de l'adaptateur de cathéter et s'étendant au plan distal au-delà du nez. L'ensemble cathéter peut en outre comprendre un capuchon d'aiguille (36), qui peut être accouplé de manière amovible au nez de l'adaptateur de cathéter. Une surface interne du capuchon d'aiguille peut être lisse et peut entrer en contact avec la nervure de réduction de contrainte.
