Claims29
A discharge device for a liquid pharmaceutical medium, said device comprising
- a reservoir for storing the medium,
- a pressure generator for pressurizing the medium,
- a discharge opening for discharging the medium and
- a discharge valve with a valve seat and a valve body which is movable relative to the valve seat between an open position and a closed position,
- wherein
- an electrical valve actuating device is provided by means of which a force can be applied to the valve body by an electrical valve control current.
A method for discharging a liquid pharmaceutical medium by means of a discharge device, comprising a discharge process comprising the steps of:
- a. applying a pressure p1 within a pressure chamber by a pressure generator to the medium;
- b. opening a discharge valve medium discharge purposes and c. closing the discharge valve following an opening time t by an electrical control signal in order to terminate discharge of the medium.
