Abstract

A device comprising:

• • means for obtaining a parameter of a sample of body fluid from a user;
  • means for using information provided by one or more sensors to calculate a measure of physical activity of the user;
  • means for calculating a medicament dose using at least in part the measured parameter and the measure of physical activity of the user; and
  • means for indicating the calculated medicament dose to the user.

Claims

1-15. -15. (canceled)

16. A device comprising:

means for obtaining a parameter of a sample of bodily fluid from a user;

means for using information provided by one or more sensors to calculate a measure of physical activity of the user;

means for calculating a medicament dose using at least in part the measured parameter and the measure of physical activity of the user; and

means for indicating the calculated medicament dose to the user.

17. A device as claimed in claim 16, wherein the means for calculating the medicament dose is configured to use also a measure of physical activity intensity to calculate the medicament dose.

18. A device as claimed in claim 16, wherein the means for calculating the medicament dose is configured to use also a time elapsed between an instance of physical activity and a current time to calculate the medicament dose.

19. A device as claimed in claim 16, wherein the means for calculating the medicament dose is configured to use also a duration of physical activity to calculate the medicament dose.

20. A device as claimed in claim 19, wherein the means for calculating the medicament dose is configured to integrate physical activity intensity with respect to time and to use the result of the integration to calculate the medicament dose.

21. A device as claimed in claim 16 wherein the one or more sensors include a pedometer and the measure of physical activity is a number of steps taken by the user within a predetermined period.

22. A device as claimed in claim 21, wherein the pedometer is integrated with the device.

23. A device as claimed in claim 16, wherein the one or more sensors include an accelerometer integrated with the device.

24. A device as claimed in claim 16, wherein the device includes a communications receiver configured to receive information from external one or more sensors.

25. A device as claimed in claim 24, wherein the device is configured to verify that information received using the communications receiver relates to a user registered with the device and to disregard information other than verified information when calculating the medicament dose.

26. A device as claimed in claim 24, wherein the device is configured to receive information relating to heart rate and/or blood pressure of a user and to calculate the measure of physical activity by processing the heart rate and/or blood pressure information.

27. A device as claimed in claim 24, wherein the device is configured to receive information relating to a number of steps taken by a user from an external pedometer and to calculate the measure of physical activity by processing the steps information.

28. A device as claimed in claim 24, wherein the device is configured to receive information relating to work done by the user or power exerted by the user from an external ergometer and to calculate the measure of physical activity by processing the work done or power information.

29. A device as claimed in claim 16, wherein the means for obtaining a parameter comprises blood glucose measurement means.

30. A method of operating a device, the method comprising:

obtaining a parameter of a sample of bodily fluid from a user;

using information provided by one or more sensors to calculate a measure of physical activity of the user;

calculating a medicament dose using the measured parameter and the measure of physical activity of the user; and

indicating the calculated medicament dose to the user.
