Abstract
The present disclosure relates to an injector device comprising: a housing having a distal end and a proximal end; a medicament cartridge disposed within the housing; a needle unit comprising a needle, the needle unit being disposed in the distal end of the housing; and a button disposed in the proximal end of the housing, the button being configured to move the cartridge onto the needle unit to fluidly connect the needle with the cartridge when, in use, the button is pressed from an initial position into a depressed position.
Claims19
An auto-injector device comprising:
- a housing having a distal end and a proximal end;
- a medicament cartridge disposed within the housing;
- a needle unit comprising a needle, the needle unit being disposed in the distal end of the housing;
- a button disposed in the proximal end of the housing, the button being configured to directly act on the medicament cartridge to move the medicament cartridge onto the needle unit to fluidly connect the needle with the medicament cartridge when, in use, the button is pressed from an initial position into a depressed position during use
- a plunger displaceable to drive medicament from the medicament cartridge through the needle;
- a plunger mechanism triggerable to displace the plunger during operation of the auto-injector device;
- and
- a sleeve displaceable along a longitudinal axis of the auto-injector device between a first position in which the sleeve conceals the needle and a second position in which the needle is exposed from an end of the sleeve,
- wherein the sleeve is configured to trigger the plunger mechanism when, the sleeve is moved from the first position to the second position during use.
