Abstract
The problem of the invention is to so develop known dispensers, that it is possible to very precisely determine the actual discharged medium volume. A dispenser according to the invention has a media path, which leads from a medium storage container to a discharge opening. A delivery device for delivering medium is located in said media path. The media reservoir stores a medium, particularly a fluid, which preferably incorporates at least one pharmaceutical substance. A media discharge can be brought about by means of an operating means. According to the invention, on the dispenser is provided an electronic detecting device for detecting a quantity representing the amount of medium discharged.
Claims23
Dispenser for a medium, said dispenser comprising:
- a storage container;
- a discharge opening;
- a medium path linking the storage container and the discharge opening;
- a delivery device for delivering medium from the storage container via the medium path to the discharge opening as a function of the operation of an operating device, said operating device comprising an electronic detecting unit for producing a signal representing the discharged medium quantity, the delivery device being a manually operable piston pump having a stroke path;
- and
- at least one sensor for detecting at least indirectly values representing the stroke path of the piston.
Dispenser for a medium, said dispenser comprising:
- a storage container;
- a discharge opening;
- a medium path linking the storage container and the discharge opening;
- a delivery device for delivering the medium from the storage container via the medium path to the discharge opening as a function of the operation of an operating device said operating device comprising an electronic detecting unit for producing a signal representing the discharged medium quantity, the dispenser containing a servo device cooperating with the delivery device for controlling the function of said delivery device, and wherein said detecting unit controls said servo device.
Dispenser for a medium, said dispenser comprising:
- a storage container;
- a discharge opening;
- a medium path linking the storage container and the discharge opening;
- a delivery device for delivering the medium from the storage container via the medium path to the discharge opening as a function of the operation of an operating device said operating device comprising an electronic detecting unit for producing a signal representing the discharged medium quantity;
- and
- a switchable operating barrier for blocking the discharge of medium under control of the detecting unit.
Dispenser for a medium, said dispenser comprising:
- a storage container;
- a discharge opening;
- a medium path linking the storage container and the discharge opening;
- a delivery device for delivering the medium from the storage container via the medium path to the discharge opening as a function of the operation of an operating device, said operating device comprising an electronic detecting unit for producing a signal representing the discharged medium quantity;
- and
- a data exchange device through which the data detected by the detecting unit can be transmitted to at least one dispenser-external data processing device.
Dispenser for a medium, said dispenser comprising:
- a storage container;
- a discharge opening;
- a medium path linking the storage container and the discharge opening;
- a delivery device for delivering the medium from the storage container via the medium path to the discharge opening as a function of the operation of an operating device said operating device comprising an electronic detecting unit for producing a signal representing the discharged medium quantity;
- the medium being a fluid containing at least one pharmaceutical substance.
Dispenser system for a medium comprising:
- a dispenser having a storage container, a discharge opening, a medium path connecting the container with the opening, a manually operable pump between container and opening, a flow volume meter in the medium path producing electric signals, a data processing unit for receiving and processing the signals in order to generate data, an electronic memory for storing the data including data for time and number of pump operations, a data output dispenser;
- further comprising an external station, having a data input for receiving the data from the data output, data output and input being connected in a wireless manner.
