Abstract

The invention relates to a dosing device that comprises a medium reservoir ( S) and a pump device for dosing and dispensing a medium stored in said medium reservoir. The pump device is associated with a pump chamber, and with at least one inlet and one outlet valve. According to the invention, the inlet valve is configured as a sliding valve (10, 12) which, in its closed positio n, can be displaced by a dosing stroke that defines a dosing volume for the pum p chamber (17). The invention further relates to the use of said dosing device for dispensing pharmaceutical active substances, especially for nasal administration.

Claims (7)

1. Dosing device with a medium reservoir (S), as well as with a pumping device for dosing and dispensing a medium stored in the medium reservoir, a pump chamber, at least one inlet valve and at least one outlet valve being associated with the pumping device, characterized in that the inlet valve is constructed as a slide valve (10, 12), which is movable over a dosing stroke in its closed position and this defines a dosing volume for the pump chamber (17).
2. Dosing device according to claim 1, characterized in that on both sides the slide valve (10, 12) can be transferred into an open position over and beyond the dosing stroke.
3. Dosing device according to claim 2, characterized in that the dosing stroke is formed by a housing-side dosing channel (13) matched to the contour of the slide valve (10, 12), which is bounded both towards the pump chamber (17) and to-wards the medium reservoir by in each case a cross-sectional widening.
4. Dosing device according to claim 1, characterized in that the pump chamber has at least one housing-side reception space (14), with which is associated a displacement body (11 ) movable together with the slide valve (10, 12) and whose shape is matched to the cross-section of the reception space (14) in such a way that, on insertion into the reception space (14), the displacement body (11 ) almost completely fills the same.
5. Dosing device according to claim 1, characterized in that a pump spring ar-rangement (15) serving as a return stroke drive is positioned outside the flow paths of the medium to be dispensed and in particular outside the pump chamber (17).
6. Dosing device according to claim 1, characterized in that a return stroke spring arrangement associated with a valve body (16) of the outlet valve is positioned separately from the flow path of the medium to be dispensed.
7. Pumping device for a dosing device according to claim 1, characterized in that the pumping device is designed as a subassembly manufactured separately from the dosing device and detachably connectable to the dosing device.
