Dispensing device
A dispensing device for dispensing a number of doses of medication to a patient, comprising a dispensing mechanism for dispensing the medication by actuation of the dispensing mechanism from a non-dispensing position to a dispensing position, a dose counter for counting the number of doses dispensed by said device, a first battery-less arrangement for providing power to said dose counter in response to the actuation of said dispensing mechanism, and an electronic display for displaying a dose indication, characterised in that the device includes a second battery-less arrangement for providing power to said electronic display when said dispensing mechanism is in said non-dispensing position.
1. A dispensing device for dispensing a number of doses of medication to a patient, comprising
a dispensing mechanism for dispensing the medication by actuation of the dispensing mechanism from a non-dispensing position to a dispensing position,
a dose counter for counting the number of doses dispensed by said device,
a first battery-less arrangement for providing power to said dose counter in response to the actuation of said dispensing mechanism, and
an electronic display for displaying a dose indication,
characterised in that the device includes a second battery-less arrangement for providing power to said electronic display when said dispensing mechanism is in said non-dispensing position.
2. A dispensing device according to claim 1 , wherein said first battery-less arrangement includes an electromechanical generator.
3. A dispensing device according to claim 1 , wherein, said second battery-less arrangement includes an electromechanical generator.
4. A dispensing device according to claim 3 , wherein said first battery-less arrangement and second battery-less arrangement include the same electromechanical generator.
5. A dispensing device according to claim 3 , wherein the second battery-less arrangement includes an actuator for manually actuating the electromechanical generator, said actuator being different from the dispensing mechanism.
6. A dispensing device according to claim 2 , wherein said electromechanical generator comprises a rack and pinion assembly.
7. A dispensing device according to claim 1 , wherein said electronic display is a liquid crystal display.
8. A dispensing device according to claim 1 , wherein said dose counter includes an electronic circuit and a non-volatile memory.
9. A method of dispensing a number of doses of medication to a patient using a dispensing device, said dispensing device comprising a dispensing mechanism for dispensing the medication by actuation of the dispensing mechanism from a non-dispensing position to a dispensing position, a dose counter for counting the number of doses dispensed by said device, an electronic display for indicating a dose count, the method comprising:
operating a first battery-less arrangement for providing power to said dose counter when said dispensing mechanism is in said dispensing position, and
operating a second battery-less arrangement for providing power to said electronic display when said dispensing mechanism is in said non-dispensing position.
