Abstract
(EN)
A catheter assembly (12) may include a catheter hub (14) and a catheter tube (22), which may extend distally from the catheter hub. The catheter assembly may include a push tab (24) and one or more ribs (26) extending outwardly from an upper portion of the catheter hub. The ribs may be shorter in height than the push tab and proximal to the push tab. A needle assembly (28) may include a needle hub (30), an introducer needle (32) extending distally from the needle hub and through the catheter tube, and a grip (36a, 36b) coupled to the needle hub. The grip may include a face (38a, 38b) disposed outwardly from the push tab and the ribs. A grip of a user may contact the push tab, the ribs, and the face to reduce rotation between the catheter hub and the needle hub in response to distal advancement of the catheter hub.
(FR)
L'invention concerne un ensemble cathéter (12) qui peut comprendre un embout de cathéter (14) et un tube de cathéter (22), qui peut s'étendre de manière distale à partir de l'embout de cathéter. L'ensemble cathéter peut comprendre une languette-poussoir (24) et une ou plusieurs nervures (26) s'étendant vers l'extérieur à partir d'une partie supérieure de l'embout de cathéter. Les nervures peuvent être plus courtes en hauteur que la languette-poussoir et situées à proximité de la languette-poussoir. Un ensemble aiguille (28) peut comprendre une embase d'aiguille (30), une aiguille d'introduction (32) s'étendant de manière distale à partir de l'embase d'aiguille et dans le tube de cathéter, et une poignée (36a, 36b) couplée à l'embase d'aiguille. La poignée peut comprendre une face (38a, 38b) disposée vers l'extérieur à partir de la languette-poussoir et des nervures. Une prise d'un utilisateur peut mettre en contact la languette-poussoir, les nervures et la face pour réduire la rotation entre l'embout de cathéter et l'embase d'aiguille en réponse à une avancée distale de l'embout de cathéter.
