Patent ID: 7725286

Claim:
A device for measuring the body temperature of a living being, the device comprising: a sensor housing; a first temperature sensor connected to said sensor housing for placement on the skin of the body for detecting a skin temperature of the living being; a second temperature sensor connected to said sensor housing and arranged on a side of said first temperature sensor facing away from the body at a spaced location therefrom for detecting another temperature; an analyzing unit for calculating body temperature according to a predetermined temperature formula containing a temperature difference, which is calculated from the temperatures measured by said first temperature sensor and said second temperature sensor and a compensation term expanding the temperature formula, said compensation term depending on a change over time in a sensor temperature based on said detected skin temperature and said another temperature and parameters for determining a temperature correction value to take into account the heating of said sensor housing and/or a heating of a space surrounded by said sensor housing by the contact between said sensor housing and the skin of the body, said analyzing unit having a computing means and a storage means, wherein at least two consecutive values of said sensor temperature measured at a predetermined time interval are stored in said storage means.
