Claim 0:
1. An injector device comprising:
a housing;
a cartridge having a reservoir for medicament;
a needle unit comprising a needle, wherein prior to use of the injector device the needle is sealed from the reservoir; and
a needle sleeve rotatably mounted to the housing about an axis, wherein a distal end of the needle sleeve defines an opening configured to allow a distal end of the needle to pass through,
wherein at least one of the needle unit or the cartridge is axially slidably mounted to the housing, and
wherein the needle sleeve comprises an engagement member arranged to engage the needle unit or the cartridge, the engagement member being adapted such that rotation of the needle sleeve moves the needle unit or the cartridge in an axial direction to move the needle into fluid communication with the reservoir, wherein the needle sleeve is axially slidably mounted to the housing, and wherein after the rotation of the needle sleeve, the engagement member disengages from the needle unit or the cartridge so that the needle sleeve can move axially independently of the needle unit and the cartridge.
