ABSTRACT:
The invention relates to a training device for an automatic injector, comprising a cylindrical outer sleeve, in the rear portion of which a discharge mechanism is connected and in the front portion of which a holder for a punch member is accommodated 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 so that the front prod-shaped end portion, which has such dimensions that it can pass throuogh the central aperture in the nose portion of the holder outward, is present inside the holder prior to use of the device. The rear end portion of the punch member comprises means which, in cooperation with means provided on the inner wall of the resilient sleeve-like rear portion of the holder, prevent undesired backward movement of the punch member in the holder in which, however, at the area of said means the device is proportioned so that after activation the wall of the holder can expand resiliently outward within the outer sleeve so as to allow the punch member to pass. A spring is present between the punch member and the locking device which enables locking of the plunger, making the device ready for reuse.
