A safety intravenous catheter assembly (10), and method for use with a needle (12) is comprised of the following. A catheter hub (18) has an axial bore (20) extending through the catheter hub (18). A needle cover (22) has a first end (24) of the needle cover (22) inserted in the axial bore (20), a second axial bore (26) extending through the needle cover (22), and coaxial with the axial bore (20). A continuous circumferential notch (28) extends outwardly in the axial bore (20) of the catheter hub (18). A notch clip (30) is joined with the needle cover (22), and is positional to engage the notch (28) of the catheter hub (18). The notch clip (30) can engage a side (14) of the needle (12), the notch (28), which locks the catheter hub (18) in engagement with the needle cover (22) when the needle cover (22) is inserted in the axial bore (20), and the needle (12) is inserted in the second axial bore (26) at least adjacent or past a distal portion (32) of the notch clip (30).

L'invention concerne un ensemble (10) cathéter intraveineux de sécurité et l'utilisation de celui-ci avec une aiguille (12). Cet ensemble comprend un embout (18) de cathéter comprenant un passage (20) axial traversant. Un élément (22) de protection d'aiguille dont une première extrémité (24) est insérée dans le passage (20) axial, est traversé par un second passage (26) axial, ce second passage (26) étant coaxial au premier passage (20) axial. Une encoche (28) circulaire continue s'étend vers l'extérieur dans le passage (20) axial de l'embout (18) du cathéter. Un taquet (30) d'encoche est monté sur l'élément (22) de protection d'aiguille et peut être placé de manière à s'engager dans l'encoche (28) de l'embout (18) de cathéter. Le taquet (30) peut venir s'appuyer à la fois sur un côté (14) de l'aiguille et dans l'encoche (28) ce qui verrouille l'embout (18) de cathéter avec l'élément (22) de protection d'aiguille lorsque ce dernier est inséré dans le passage (20) axial, et l'aiguille (12) est insérée dans le second passage (26) axial de manière à se trouver au moins adjacente à la partie (32) distale du cliquet (30) ou au delà de cette dernière.
