Granted: 2009-11-24
Abstract: Une seringue de mélange, présentant une première chambre scellée contenant une poudre (boîtier de poudre) et une deuxième chambre scellée contenant un liquide (boîtier de liquide). Lorsque l'utilisateur a besoin d'injecter un patient, il ou elle tient la seringue en position environ horizontale et appuie sur un piston. Ce mouvement provoque un perceur à percer une pellicule en aluminium séparant les deux chambres. Le liquide descend ensuite vers le bas dans le boîtier de poudre. Le liquide coule à travers un passage dans un piston situé dans le boîtier de poudre, où il vient alors en contact avec la poudre.   mesure que l'utilisateur continue d'appuyer sur le piston vers le bas, le perceur vient se reposer dans le piston et scelle le passage à travers le piston, verrouillant le perceur et le piston ensemble. Le dispositif est alors prêt pour une injection. mesure que le piston est enfoncé davantage, le piston expulse la poudre et le mélange de liquide à travers une aiguille.
