Abstract:
A medication delivery device (1) comprises a housing (4) having a proximal end (P) and a distal end (D), a cartridge (3) for holding a medication (M), the cartridge (3) having an outlet (2), a moveable piston (5) being retained within the cartridge (3), a drive member (17) moveable in a proximal direction with respect to the housing (4) for setting a dose of medication (M) to be delivered and in the distal direction with respect to the housing (4) for delivering the dose and a piston rod (10) adapted to drive the piston (5) in a distal direction with respect to the cartridge (3) for delivering the dose. The drive member (17) is releasably coupled to the piston rod (10). The medication delivery device (1) further comprises a resilient member (21) which is arranged to move the drive member (17) in the proximal direction with respect to the housing (4) after dose delivery, thereby reducing pressure of the piston rod (10) on the piston (5).
