Title (EN) SYRINGE WITH RETRACTABLE NEEDLE MOUNT
(FR) SERINGUE A SUPPORT D'AIGUILLE RETRACTABLE
Abstract:
(EN) A retractable syringe in which the forward end (70) of the plunger (14) as it reaches its fully depressed position actively deforms and releases a snap lock mechanism (50, 58) securing a mount (16) for the syringe needle at the forward end of the syringe barrel (20). The plunger (74) then captures and in an upward stroke withdraws the needle mount and an associated hypodermic needle into the barrel. In a preferred arrangement the needle capturing mechanism (54, 70) allows or biases the needle into a canted orientation with its tip (78) against the interior wall of the barrel. Alternatively an internal mechanism (102, 122) within the plunger propels the captured needle mount and needle into the body (103) of the plunger following release of the snap lock mechanism (50, 58) retaining the needle mount at the forward end of the barrel (20).
(FR) Seringue rétractable dans laquelle l'extrémité avant (70) du piston (14), lorsqu'elle atteint sa position la plus basse, déforme activement et libère un mécanisme de blocage à déclic (50, 58) formant support (16) pour l'aiguille de la seringue à l'extrémité avant du cylindre (20) de la seringue. Le piston (74) s'empare alors du support de l'aiguille ainsi que d'une aiguille hypodermique intégrée et les tire à l'intérieur du cylindre lors d'une course vers le haut. Dans un agencement préférentiel, le mécanisme de prise de l'aiguille (54, 70) place l'aiguille en position inclinée avec sa pointe (78) contre la paroi intérieure du cylindre. Alternativement, un mécanisme interne (102, 122) à l'intérieur du piston propulse le support d'aiguille et l'aiguille prisionniers dans le corps (103) du piston après libération du mécanisme de blocage à déclic (50, 58) retenant le support de l'aiguille à l'extrémité avant du cylindre (20).
