Title
(EN) SAFETY SYRINGE
(FR) SERINGUE DE SÉCURITÉ
Abstract
(EN)
A safety syringe comprising a barrel having an opening at an end thereof and a bung positioned in the barrel and creating a volume between the opening and the bung. The safety syringe also comprises a handle portion secured to the barrel and a syringe plunger slidably engaged with the handle portion and moveable within the barrel on an inward stroke to drive the bung forwards within the barrel to cause a substance within the volume to be expelled from the opening. The safety syringe further comprises a rotation mechanism configured to rotate the syringe plunger within the barrel at a point during the inward stroke when the syringe plunger is in contact with the bung, such that a rotational force is applied to the barrel and a brake connected to the handle portion and configured to provide a frictional force to resist the rotational force applied to the barrel.
(FR)
L'invention concerne une seringue de sécurité comprenant un cylindre ayant une ouverture à une de ses extrémités et un bouchon positionné dans le cylindre et créant un volume entre celui-ci et l'ouverture. La seringue de sécurité comprend également une partie poignée fixée au cylindre et un piston de seringue engagé de façon coulissante dans la partie poignée et pouvant se déplacer à l'intérieur du cylindre sur une course vers l'intérieur pour entraîner le bouchon vers l'avant à l'intérieur du cylindre afin d'expulser une substance contenue dans le volume de l'ouverture. La seringue de sécurité comprend en outre un mécanisme de rotation configuré pour faire tourner le piston de seringue à l'intérieur du cylindre à un point pendant la course vers l'intérieur lorsqu'il est en contact avec le bouchon, de telle sorte qu'une force de rotation est appliquée au cylindre et qu'un frein est relié à la partie de poignée et configuré pour fournir une force de frottement afin de contrer la force de rotation appliquée au cylindre.
