Abstract

La présente invention concerne un capuchon pour seringue de type stylo contenant une unité de mise au rebut de l'aiguille, conçu de sorte qu'après utilisation, un embout, sur lequel est montée une aiguille (aiguille d'injection), soit séparé/éjecté de la seringue après pliure de l'aiguille. Plus particulièrement, la présente invention concerne un capuchon de seringue de type stylo contenant une unité de mise au rebut de l'aiguille, conçu de sorte que, lorsqu'un embout déjà utilisé est inséré dans l'espace interne du capuchon, l'aiguille est pliée par la pression d'insertion, la seringue et l'embout sont tournés et séparés par dévissage et l'embout est éjecté de l'intérieur du capuchon vers l'extérieur du capuchon par une seule pression. La présente invention est caractérisée en ce qu'elle comprend : une unité de compression d'aiguille positionnée à l'intérieur d'une unité de logement de corps de capuchon et dotée d'une rainure d'insertion d'extrémité supérieure de l'embout, qui présente une surface de compression d'aiguille sur son côté; une unité de tige de poussée conçue selon une forme cylindrique, l'extrémité supérieure de l'unité de tige de poussée étant reliée à l'extrémité inférieure d'une unité de plaque de pression de tige de poussée et l'extrémité inférieure de l'unité de tige de poussée étant reliée à l'unité de compression d'aiguille; une unité de plaque de pression de tige de poussée, qui est positionnée à l'extérieur de l'unité de logement de corps de capuchon, qui présente une extrémité inférieure reliée à l'unité de tige de poussée et qui est pressée lorsqu'un embout ayant une aiguille pliée est éjecté; et une unité de logement de collier ayant une unité de compression d'aiguille sur sa portion inférieure, l'unité de logement de collier étant conçue de sorte que l'unité de compression d'aiguille et l'unité de tige de poussée se déplacent à l'intérieur d'un trou traversant ménagé à l'intérieur. Le trou traversant de l'unité de logement de collier a une différence de niveau définie entre le rayon interne de sa partie supérieure et le rayon interne de sa partie inférieure.
