Title
(EN) A RETAINED NEEDLE STRUCTURE
(FR) STRUCTURE POUR RETENTION D'AIGUILLE
Abstract
(EN) A retained needle structure is disclosed, which comprises a needle operating body (1), a catheter assembly ( 2) and a house ( 3), at least one locking portion ( 12) being installed on the needle operating body ( 10), an opening being ( 31) formed on the front end of the house ( 3 ), several projected engaging portions ( 312) being formed on the opened front end, several sliding parts ( 32) being extended at the rear portion of the house ( 3 ) corresponding to the position and number of the needle operating body (1), a sliding slot ( 321) being formed on each sliding part ( 32), near to the end of each sliding slot (321) being a portion of sloping downward (323), a projecting part (322) being installed on the front end of the portion of sloping downward (323), the catheter assembly (2) being formed by a manner that a sleeve (21) is mounted on a catheter hub (11), a needle (111) of the needle operating body (1) being extended within a flexible catheter ( 22), so that the locking portion ( 12 ), each is inserted into the relative sliding slot (321), for the house ( 3 ) to slide on the needle operating body (1).
(FR) Cette invention concerne une structure pour rétention d'aiguille comprenant un corps de commande d'aiguille (1), un ensemble cathéter (2) et un boîtier (3), au moins une partie de blocage (12) montée sur le corps de commande d'aiguille (1), une ouverture (31) à l'avant du boîtier (3), plusieurs saillies d'engagement (312) sur l'extrémité avant ouverte, plusieurs pièces coulissantes (32) sortant à l'arrière du boîtier (3) et correspondant à la position et au numéro du corps de commande d'aiguille (1), une gorge de coulissement (321) sur chaque partie coulissante (32), la partie proche de l'extrémité de chaque gorge de coulissement (321) se terminant en biseau (323), et une partie saillante formée sur la partie en biseau (323). L'ensemble cathéter (2) comporte un manchon (21) monté sur son moyeu (11). Une aiguille (111) du corps de commande d'aiguille (1) pénètre dans un cathéter souple (22) de sorte que la partie ce blocage s'insère dans la gorge de coulissement correspondante (321) et que le boîtier (3) coulisse sur le corps de commande d'aiguille (1).
