Injection device

Abstract:

An injection device comprising: a housing arranged to contain a syringe with a piston for sealing the syringe and displacing the medicament, the housing having a proximal end and a distal end, wherein the distal end is intended to be applied against an injection site; a driving mechanism arranged between the piston and the proximal end of the housing; and a locking mechanism comprising a plate member arranged between the driving mechanism and the piston to retain the driving mechanism to retain the driving mechanism in an initial inactive state in which the driving mechanism cannot be actuated; wherein when the locking mechanism is released, the driving mechanism can be actuated to push the piston towards the distal end of the housing to displace the medicament.
