Title
(EN) SINGLE USE SYRINGE WITH BREAKAWAY PLUNGER
(FR) SERINGUE A USAGE UNIQUE AVEC PISTON FRANGIBLE
Abstract
(EN)
A syringe is provided that comprises a plunger (10) which is adapted to be locked in place when it is fully compressed. The plunger comprises a frangible section (24) which has a breaking strength less than the holding strength of the locking structure. Thus, if an attempt is made to withdraw the plunger and reuse the syringe after the plunger has been fully compressed, the plunger will break, rather than withdrawing from the syringe barrel.
(FR)
L'invention concerne une seringue comprenant un piston (10) conçu pour être verrouillé en place lorsqu'il est entièrement enfoncé. Ce piston comporte une section (24) frangible dont la résistance à la rupture est inférieure à la force de retenue de la structure de verrouillage. Ainsi en cas de tentative de retrait du piston en vue d'une réutilisation de la seringue après que le piston a été entièrement enfoncé, le piston se rompt plutôt que de sortir du corps de la seringue.
