Abstract

A device for administering a fluid product, including a container for the fluid product, an apparatus for dispensing the fluid product from the container, a metering apparatus for adjusting a product dose, and at least one temperature sensor disposed inside the container or near the fluid product. The present invention also encompasses a method for controlling the administration of a fluid product, wherein a metered quantity of a product dose, which is to be administered, is adjusted in accordance with the temperature of the fluid product and/or the temperature of the surroundings of the fluid product.

Claims

1. A device for administering a fluid product, comprising:

a) a container for the fluid product;

b) a dispensing means for administering the fluid product from the container;

c) a dosing means for setting a product dosage; and

d) at least one temperature sensor for measuring at least one of the temperature of the fluid product and the temperature in the vicinity of the fluid product.

2. The administering device as set forth in claim 1, wherein the at least one temperature sensor is arranged on or in the container.

3. The administering device as set forth in claim 1, further comprising alarm means for outputting an alarm signal when a temperature difference with respect to a reference temperature is exceeded.

4. The administering device as set forth in claim 3, wherein the alarm signal is an acoustic, visual and/or vibration alarm signal.

5. The administering device as set forth in claim 1, wherein the dosing means sets the product dosage in accordance with the temperature measured by the temperature sensor.

6. The administering device as set forth in claim 1, further comprising monitoring means for monitoring an occlusion and/or leak in the administering device, said monitoring means settable in accordance with the temperature measured by the temperature sensor.

7. A method for controlling the administering of a fluid product from a container for the fluid product, comprising using a dosing means to set a dosage amount of a product dosage to be administered, wherein the dosage amount is set in accordance with at least one of a temperature of the fluid product and a temperature of the environment near the container.

8. The method as set forth in claim 7, wherein the dosage amount is set in accordance with a temperature difference with respect to a reference temperature.

9. The method as set forth in claim 8, wherein a predetermined dosage amount is changed when the temperature difference is exceeded.

10. The method as set forth in any one of claim 9, wherein the predetermined dosage amount is changed when the temperature difference is exceeded within a predetermined period of time.

11. The method as set forth in any one of claim 7, wherein the dosage amount is changed automatically.

12. The method as set forth in any one of claim 10, wherein the dosage amount is changed automatically.

13. The method as set forth in any one of claims 8, wherein an alarm is outputted when the temperature difference is exceeded.

14. The method as set forth in claim 7, further comprising providing a monitoring means for monitoring an occlusion and/or leak in an administering device, wherein a limit value of the monitoring means is set in accordance with at least one of the temperature of the fluid product and the temperature of the environment near the container.
