Title
(EN) SYSTEM FOR SAFETY SYRINGE
(FR) SYSTÈME POUR SERINGUE DE SÉCURITÉ
Abstract
(EN) A system for serially injecting liquids includes a syringe body defining a syringe proximal opening and a distal needle interface, proximal and distal stopper members, forming proximal and distal chambers. The system also includes a first liquid in the distal chamber and a second liquid in the proximal chamber, and a plunger configured to be manually manipulated to insert the proximal stopper member distally. Moreover, the system includes a needle hub assembly coupled to the syringe body, the needle assembly including a needle. The needle defines a needle interior, and distal, middle and proximal openings. The distal, middle and proximal openings are fluidly coupled through the needle interior. Manipulating the plunger member to insert the proximal stopper member initially expels the first liquid from the distal chamber, then serially expels the second liquid from the proximal chamber.
(FR) L'invention concerne un système d'injection en série de liquides qui comprend un corps de seringue délimitant une ouverture proximale de seringue et une interface d'aiguille distale, des éléments de butée proximal et distal, formant des chambres proximale et distale. Le système comprend également un premier liquide dans la chambre distale et un second liquide dans la chambre proximale, et un piston conçu pour être manipulé manuellement de façon à insérer l'élément de butée proximal de manière distale. De plus, le système comprend un ensemble embase d'aiguille accouplé au corps de seringue, l'ensemble aiguille comprenant une aiguille. L'aiguille délimite un intérieur d'aiguille, ainsi que des ouvertures distale, intermédiaire et proximale. Les ouvertures distale, intermédiaire et proximale sont en communication fluidique par l'intermédiaire de l'intérieur de l'aiguille. La manipulation de l'élément de piston pour insérer l'élément de butée proximal expulse initialement le premier liquide de la chambre distale, puis expulse en série le second liquide de la chambre proximale.
