CA2390477C — Method for reconstituting an injection liquid and an injection appliance for carrying out such a method

USPTO Abstract

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.
