Abstract: The present invention relates to a medication delivery device comprising pump means and a reservoir adapted for containing a medicament. The pump means is adapted to transfer the medicament from the reservoir to an outlet arrangement, said outlet arrangement being adapted to be operatively connected to an associated hypodermic needle. The pumps means is adapted to deliver a set dose of medicament during one or more pump strokes, wherein the stroke volume(s) of said one or more pump strokes is variable. The present invention further relates to a method for adjusting stroke volumes to a set dose of medicament.

Abstract: An automatic needle insertion device for a pen shaped syringe comprising a cartridge holder (2) wherein a cartridge with a drug can be accommodated, and a dose setting and injection part (1) by which a wanted dose may be set an subsequently pressed out from the cartridge by pressing a button (12) projecting from the dose setting and injection part (1). The device comprises a mainly tubular housing (31) in which a tubular pen holder (22) in which a pen can be mounted can be axially displaced in a proximal direction to cock a spring (30) which can thereafter be released to drive the pen holder (22) with the pen a set distance in a distal direction.
