Mechanical self-actuated system for particular pharmaceutical packs the contents of which shall be administered as an atomized spray of exact small doses, said packs being either of the multi-use or the single-use type and having incorporated therein a dosing pump to be actuated manually with a given force to ensure a perfect atomization; however, patients cannot exert or measure said force exactly and thus they cause insufficient and not atomized dispensations; the system according to this invention aims to avoid this disadvantage by using a spring-loaded self-actuated head with a first manual actuation step for loading the spring (9) and a successive snap-release step by the action of a mechanical self-release (5, 6, 7) at the end of the stroke for actuating the delivery pump, said pump being therefore actuated with the exact force for an optimum atomization, said force depending only upon the exact choice of the spring (9). |
