Abstract
The invention relates to a training device for an automatic injector. The device comprises a cylindrical outer sleeve in the rear portion of which a discharge mechanism is connected and in the front portion of which a holder intended for accommodating a punch member is incorporated so as to be locked against forward movement. The discharge mechanism comprises a plunger, a coil spring which acts on the plunger, a locking device and a safety member. The holder for the punch member comprises a sleeve-like rear portion which is open at each end. The punch member is accommodated in the holder such that its rear end at least substantially engages the front end of the plunger, and such that the front prod-shaped end portion which has dimensions such that it can pass through the central aperture in the nose portion of the holder outwards, is present within the holder prior to use of the device. The device further comprises auxiliary means for making the device ready for reuse. The rear end portion of the punch member comprises means which, in cooperation with means provided on the inner wall of the sleeve-like rear portion of the holder, prevent undesired forward movement of the punch memb…
