Abstract

L'invention concerne un mécanisme de commutation circulaire pour seringue (1), comprenant un cylindre intérieur (40), un ensemble cylindre de guidage hélicoïdal bidirectionnel (50) disposé à l'intérieur du cylindre intérieur (40) et un ensemble piston d'injection (90) disposé à l'intérieur de l'ensemble cylindre de guidage hélicoïdal bidirectionnel (50). L'ensemble cylindre de guidage hélicoïdal bidirectionnel (50) comprend un cylindre de guidage hélicoïdal extérieur (51) et un cylindre de guidage hélicoïdal intérieur (52) disposé à l'intérieur du cylindre de guidage hélicoïdal extérieur (51). L'extrémité arrière du cylindre de guidage hélicoïdal intérieur (52) est raccordée par l'intermédiaire d'un joint mâle et femelle au couvercle terminal du piston (92) de l'ensemble piston d'injection (90). Le cylindre de guidage hélicoïdal extérieur (51) et le cylindre de guidage hélicoïdal intérieur (52) coopèrent par l'intermédiaire d'une rainure de guidage hélicoïdale (514) et d'un bloc de guidage hélicoïdal (521), de telle sorte que le cylindre de guidage hélicoïdal intérieur (52) peut tourner et avancer à l'intérieur du cylindre de guidage hélicoïdal extérieur (51). La surface extérieure du cylindre de guidage hélicoïdal intérieur (52) comporte de nombreux crans antiretour (522) et une rainure de guidage axiale (523). Le cylindre intérieur (40) utilise une saillie antiretour (42) pour changer de position entre les crans antiretour (522) du cylindre de guidage hélicoïdal intérieur (52) et la rainure de guidage axiale (523). Pendant chaque opération, l'ensemble piston d'injection (90) peut être rapidement tiré vers l'arrière de façon axiale. Lorsque l'ensemble piston d'injection (90) est à nouveau pressé axialement, la force de poussée axiale est convertie en une force de poussée rotationnelle par l'intermédiaire de l'ensemble cylindre de guidage hélicoïdal bidirectionnel (50) pour injecter une dose fixée de médicament. Ce mode de fonctionnement par commutation circulaire permet un fonctionnement simple et n'exigeant que peu de force.
