Title (EN) METHOD AND APPARATUS FOR INTRODUCING A NEEDLE FOR CATHETER PLACEMENT
(FR) PROCÉDÉ ET APPAREIL POUR INTRODUIRE UNE AIGUILLE POUR LA POSE D'UN CATHÉTER
Abstract:
(EN) A catheter assembly and method for introducing a needle (10) to position a catheter (28), such as a peripheral TV catheter into a patient includes piercing a vein (26) with a needle that extends from the distal end of the catheter. The needle has a distal tip (22) with a configuration that pierces the vein at an angle to penetrate a vein with a reduced incidence of transfixing, injury of the inner surface of the vein or inadvertently passing through side wall of the vein. The distal tip (22) of the needle is introduced into the lumen (32) of the vein at an incline where the distal tip is (22) spaced from an inner surface (34) of the vein and a bevel surface (20) of the distal tip faces the inner surface (34) of the vein opposite the entry point of the needle into the vein. A catheter (28) on the needle (10) is advanced from the distal tip of the needle into the lumen of the vein.
(FR) L'invention concerne un ensemble cathéter et un procédé pour introduire une aiguille (10) pour la pose d'un cathéter (28), tel qu'un cathéter intraveineux périphérique chez un patient, comprenant le perçage d'une veine (26) avec une aiguille qui s'étend à partir de l'extrémité distale du cathéter. L'aiguille comporte une pointe distale (22) ayant un profil permettant de percer la veine selon un certain angle pour pénétrer dans la veine avec une incidence réduite de transperçage, lésion de la surface interne de la veine ou perforation accidentelle d'une paroi latérale de la veine. La pointe distale (22) de l'aiguille est introduite dans la lumière (32) de la veine selon une inclinaison telle que la pointe distale (22) est espacée d'une surface interne de la veine et une surface biseautée de la pointe distale est en regard de la surface interne de la veine à l'opposé du point d'entrée de l'aiguille dans la veine. On fait ensuite progresser le cathéter monté sur l'aiguille de la pointe distale de l'aiguille jusque dans la lumière de la veine.
