Abstract:
1. A discharge device for discharging a pharmaceutical liquid comprising: a housing; a liquid reservoir with a receiving space for storing the pharmaceutical liquid; a discharge opening provided on the housing, the discharge opening connecting the receiving space to an environment and serving for dispensing the pharmaceutical liquid; an outlet valve between the receiving space and the discharge opening; a pre-tensioned spring device for pressurizing liquid in the receiving space of the liquid reservoir and up to the outlet valve, the pre-tensioned spring device being isolated from contact external of the discharge device for further pressurizing the liquid in the liquid reservoir in an assembled state of the discharge device; and a safety member accessible from an exterior of the discharge device, the safety member holding the spring device in a pre-tensioned state prior to an initial operation; the outlet valve being mechanically and directly openable by an actuation handle so that, upon manual opening of the outlet valve, the liquid pressurized by the spring device passes through the discharge opening, with pressure applied to the liquid by the spring device forcing the liquid through the discharge opening.
