Patent

CA 2400108

A single use syringe (10) has a needle (14) which is biased back into the barrel (11) but which is prevented from doing so by a holding means (26) which has an outer part (25) and an inner part (27) which are connected together by a frangible portion (29). The needle (14) is held by the inner part (27). When the plunger (13) is pushed towards the front of the barrel (11), it contacts the outer part (25) and pushes it forwardly which stretches the frangible portion (29) until it bursts. When the frangible portion (29) breaks, the inner portion (27) containing the needle (14) is released and can shoot back into a hollow portion (15) in the plunger (13) through a frangible portion of the plunger head (12).

La présente invention concerne une seringue à usage unique (10) comprenant une aiguille (14) qui est sollicitée en arrière vers l'intérieur du cylindre (11), mais retenue par un moyen de retenue (26) composé d'une partie extérieure (25) et d'une partie intérieure (27) reliées ensemble par une partie frangible (29). L'aiguille (14) est retenue par la partie intérieure (27). Lorsque le piston (13) est poussé vers l'avant du cylindre (11), il entre en contact avec la partie extérieure (25) qu'il pousse vers l'avant, étirant de la sorte la partie frangible (29) jusqu'à ce que cette dernière se brise. Lorsque la partie frangible (29) se brise, la partie intérieure (27) contenant l'aiguille (14) est libérée et peut alors se rétracter vers l'arrière, à travers une partie frangible de la tête (12) du piston, jusque dans une partie creuse (15) du piston (13).
