An injection device has a housing (42) for receiving a container (50) having a liquid (49; 226′). In said container (50), a piston (90) is displaceably arranged so that by means of pressure upon the distal end of said piston (90), liquid can be expelled from the container (50). Arranged displaceably in the housing (42) is a tappet (92), which is configured for contact against the distal end of the piston (90) and which enables transfer of a force to the piston (90) in the proximal direction. Associated with the tappet (92) and displaceable relative thereto is a member (91) which at its proximal end region can be joined to the piston (90) in such a way that it enables the transfer of a force in the proximal direction and the transfer of a force in the distal direction to the piston (90).
An injection device,
The injection device according to one or more of the foregoing claims, wherein the displaceable member (91) is arranged displaceably in a recess (114) of the tappet (92).
The injection device according to one of the foregoing claims, wherein the tappet is configured as a toothed rod (92).
The injection device according to one of the foregoing claims, wherein a signal member (131) that is actuable by means of the reconstitution operation is provided.
The injection device according to one or more of the foregoing claims, having a spring (200) for the storage of energy for an injection, which spring (200) can be cocked by displacement of an adjusting member (105) in the distal direction,
The injection device according to one or more of the foregoing claims, wherein the container (50) has associated with it a holder (74) which is displaceable axially in the housing (42) between a proximal and a distal end position and is configured to receive the container (50).
The injection device according to one or more of the foregoing claims, wherein a dose-setting part (58) that is displaceable in the longitudinal direction relative to the housing (42) has latch means (66) for snap-locking of a latching element (53).
A method for reconstituting an injection liquid in an injection device for subsequent use of the reconstituted injection liquid in said device,
