Abstract

A dispenser for dispensing a pharmaceutical medium, including a sensor for sensing a dispensing operation and an electronic processing circuit for sensing and further processing a signal caused by the sensor. In order to simplify the design, the sensor is part of a sensor unit, which has a radio transmitter for producing a radio signal, and the processing circuit has a radio receiver designed to receive the radio signal produced by the radio transmitter.

First claim

The invention claimed is:

1. A dispenser for dispensing a pharmaceutical medium, comprising:
a housing defining first and second spaced-apart and separate locations;
a sensor unit disposed at said first location for sensing a dispensing operation, said sensor unit including a radio transmitter for producing a radio signal, and a conversion device configured to convert mechanical energy generated during a dispensing operation of said dispenser into electrical energy, said sensor unit being configured to supply electrical energy generated by said conversion device to said radio transmitter to operate same to produce the radio signal; and
an electronic processing circuit disposed at said second location and including a radio receiver configured for receiving the radio signal produced by said radio transmitter;
said housing including a housing part configured for mounting said electronic processing circuit on said housing, said electronic processing circuit being detachable from said housing part to allow re-use or disposal of said electronic processing circuit.

2. The dispenser of claim 1 , wherein said first and second locations are disposed not more than 10 centimeters from one another on said housing.

3. The dispenser of claim 1 , wherein said housing includes a housing wall defining therein a receiving region and said dispenser comprises a container disposed in said receiving region, said conversion device being disposed within said receiving region and said electronic processing circuit being disposed outside said receiving region.

4. The dispenser of claim 1 , wherein said radio transmitter is configured to produce a radio signal according to the Bluetooth standard, the Wibree standard, the ANT+ standard or the Zigbee standard.

5. The dispenser of claim 1 , wherein said electronic processing circuit is configured for counting dispensing operations of said dispenser.

6. The dispenser of claim 1 , wherein said housing defines therein a receiving region and said dispenser includes a container disposed in said receiving region, and said conversion device is configured to convert mechanical energy generated during movement of said container within said housing into electrical energy.

7. The dispenser of claim 1 , wherein said housing includes a housing wall defining an interior configured for receiving therein a container including therein fluid to be dispensed from said dispenser, said sensor unit being disposed within said interior and said electronic processing circuit being disposed exteriorly of said housing wall and spaced from said sensor unit.

8. A dispenser for dispensing a pharmaceutical medium, said dispenser comprising:
a housing including a housing wall defining an interior region, said housing defining first and second spaced-apart locations therealong, said first location being located within said interior region and said second location being located exteriorly of said housing wall outside of said interior region;
a sensor unit disposed at said first location of said housing for sensing a dispensing operation of said dispenser, said sensor unit including a radio transmitter and a conversion device configured to convert mechanical energy generated during a dispensing operation of said dispenser into electrical energy, said conversion device being electrically connected to said radio transmitter for supplying electrical energy thereto to permit said radio transmitter to produce a radio signal;
a processing unit disposed at said second location of said housing, said processing unit including an electronic processing circuit and a radio receiver configured for receiving a radio signal from said radio transmitter; and
a container of pharmaceutical medium disposed within said interior region, said conversion device being configured to convert mechanical energy generated during movement of said container relative to said housing into electrical energy;
said conversion device comprising a piezo stack, said container compressing said piezo stack during movement of said container relative to said housing during a dispensing operation of said dispenser.

9. The dispenser of claim 8 , wherein said radio transmitter and said radio receiver are disposed not more than 10 centimeters from one another.

10. The dispenser of claim 8 , wherein said sensor unit comprises an intermediate energy storage device electrically connected to said piezo stack and to said radio transmitter such that said intermediate energy storage device supplies electrical energy generated by said piezo stack to said radio transmitter to operate same.

11. The dispenser of claim 10 , wherein said intermediate energy storage device comprises a capacitor.

12. The dispenser of claim 1 , wherein said housing includes a housing wall defining an interior and said dispenser includes a container disposed in said interior, said housing further including a housing portion movably mounted within said interior of said housing and disposed vertically beneath said container, said container being disposed to permit a downward pressure to be applied to said container by a user to cause discharge of a fluid in said container from said dispenser, wherein a downward pressure applied to said container causes displacement of said housing portion, said sensor unit being disposed within said interior of said housing vertically beneath said housing portion such that displacement of said housing portion causes said conversion device to convert mechanical energy into electrical energy.

13. The dispenser of claim 8 , wherein said housing further includes a housing portion movably mounted within said interior region vertically beneath said container, said container being disposed to permit a downward pressure to be applied to said container by a user to cause discharge of pharmaceutical medium in said container from said dispenser, wherein a downward pressure applied to said container causes displacement of said housing portion, said sensor unit being disposed within said interior region of said housing vertically beneath said housing portion such that displacement of said housing portion causes said conversion device to convert mechanical energy into electrical energy.

14. A dispenser for dispensing a pharmaceutical medium, comprising:
a container of pharmaceutical medium;
a housing configured to accommodate said container, said container being disposed relative to said housing to permit a downward pressure to be applied to said container by a user to cause a dispensing operation of said dispenser, said housing having first and second spaced-apart locations and including a housing portion, said housing portion being movably mounted within said housing and disposed vertically beneath said container such that a downward pressure applied to said container causes displacement of said housing portion;
a sensor unit disposed at said first location of said housing for sensing a dispensing operation of said dispenser, said sensor unit including a radio transmitter and a conversion device configured to convert mechanical energy into electrical energy, said conversion device being electrically connected to said radio transmitter for supplying electrical energy thereto to permit said radio transmitter to produce a radio signal, said conversion device being disposed vertically beneath said housing portion such that displacement of said housing portion during a dispensing operation causes said conversion device to convert mechanical energy into electrical energy, said sensor unit in its entirety, including said radio transmitter and said conversion device, being disposed vertically beneath said housing portion; and
