Patent

CA 2390477

The invention relates to an injection appliance that has a housing (42) for receiving a container (50) containing a liquid (49; 226'). A piston (90) is arranged in said container (50) in a displaceable manner for squeezing out liquid from the container (50) by exerting a pressure to the distal end of said piston (90). A tappet (92) that is configured in such a way that said tappet can rest on the distal end of the piston (90) is arranged in the housing (42) in a displaceable manner. Said tappet enables a force to be transmitted to the piston (90) in the proximal direction. A member (91) is allocated to the tappet (92) and can be displaced in relation thereto. The proximal end region of said member can be connected to the piston (90) in such a way that said member enables a force to be transmitted to the piston (90) in the proximal direction and enables a force to be transmitted to the piston (90) in the distal direction.

L'invention concerne un appareil pour injection muni d'un boîtier (42) pour la réception d'un contenant (50) avec un liquide (49, 226'). Un piston (90) est logé mobile dans ce contenant (50) pour pouvoir faire sortir du liquide du contenant (50) par pression sur l'extrémité distale de ce piston (90). Un coulisseau (92) logé mobile dans le boîtier (42) prend appui sur l'extrémité distale du piston (90) et permet la transmission d'une force sur le piston (90) dans le sens proximal. Au coulisseau (92) est associé un organe (91), mobile par rapport à lui, qui peut être relié au niveau de sa zone terminale proximale au piston (90) de façon à permettre la transmission au piston (90) d'une force dans le sens proximal et d'une force dans le sens distal.
