<p>A disposable injector has a housing (10) in which are arranged at least one mechanical spring energy accumulator (50), at least one cylinder-piston unit (100) that can be filled at least in part with an active substance, at least one piston actuation plunger (60) and at least one triggering unit (80). The spring energy accumulator comprises at least one pre-loaded spring element. The spring-loaded piston actuation plunger has at least one traction rod (61) with at least one support surface (63) at the rear end thereof. Locking elements (16) supported on the housing lie on the support surface(s) and are secured in the locking position by a triggering element (82) placed in a locking position (8). The triggering element has a release position (9) that causes the locking element (16) to be unlocked.</p> |
