Patent ID: 7901385

Claim:
A needleless injection device, comprising a casing; a cartridge containing a medicament for injection and an orifice at one end thereof through which the medicament is driven for injection through a patient's skin; a drive mechanism which upon actuation applies force to the medicament, forcing the medicament out of the orifice and through the patient's skin; a trigger mechanism which actuates the drive mechanism; a safety mechanism which, in a first configuration, prevents the trigger mechanism from actuating the drive mechanism and in a second configuration allows trigger mechanism to actuate the drive mechanism; and an actuator lever which moves the safety mechanism from its first configuration into its second configuration; wherein the actuator lever comprises a portion extending outside of the casing which portion is accessible to a user and which portion is comprised of a component configured such that when the portion is moved by the user the component applies a pulling force to the safety mechanism to pull the safety mechanism into its second configuration.
