Abstract

L'invention concerne une seringue comportant un tube (1) équipé à l'une de ses extrémités d'un embout (10) de montage d'une aiguille (2) avec un canal interne (2a) et dans lequel est monté à coulissement un piston (3), caractérisé en ce que le piston possède une tête d'expulsion (4) en matériau élastiquement déformable dans laquelle est ménagée une cavité ((5) pourvue d'un conduit de vidange (6) s'ouvrant en regard dudit embout (10), l'écrasement de la tête (4), obtenu par compression contre l'extrémité du tube (1) pourvue de l'embout (10) provoquant une diminution du volume de la cavité (5) et une vidange au moins partielle de celle-ci afin de créer un piston pneumatique de chasse du produit contenu dans le canal interne (2a) de l'aiguille creuse (2).
