Abstract
An injection device has a housing (112,116) wherein there is a longitudinally movable expressing member (186) for expressing an injection fluid from a fluid container (118). In order to displace the expressing member (186) longitudinally within the housing, an actuating member (170, 172) is associated therewith. The actuating member is displaceable between a proximal end position and a distal end position. Between the actuating member (170, 172) and the expressing member (186), a position-dependent connecting device (166", 167", 198, 210, 212) is provided, which is disabled in the distal end position of the actuating member (170, 172) and is enabled in a position range adjacent to the distal end position of the actuating member (170, 172) including its proximal end position. One thus obtains an injection device which is simple to operate, and which is especially adapted to permit a patient to repeatedly administer the same constant injection dose.
