Abstract
An injection deviceis described having a housingthat receives a syringe. The syringeis biased by a return springfrom an extended position in which the needleextends from the housingthrough an exit apertureto a retracted position in which it does not. A drive springacts via a drive to advance the syringefrom its retracted position to its extended position and discharge its contents through the needleand a return spring, brought into play when the drive has reached a nominal return position, restores the syringeto its retracted position. A releasable locking mechanism retains the syringein its retracted position. A sleeveprojects from the exit apertureand can be depressed to release the locking mechanism. A triggerhas a rest position, in which it engages the drive, retaining it in a position corresponding to the retracted position of the syringe, and a depressed position, in which it no longer causes the drive to be so retained. The sleevenormally locks the triggerin its rest position. However, depression of the sleeveinto the exit aperture, allows the trigger to be depressed. Thereafter, the triggeris retained in its active position.
