The invention describes and claims a method and a device for determining a core body temperature from a flow of heat from said body to a neutral medium via a first sensor element and a second sensor element, and using a dynamic model that describes the heat flow with a plurality of parameters, comprising at least the core body temperature, a temperature measured with the first sensor element, and a temperature measured with the second sensor element. Said first sensor element is arranged on a surface of the body. One of the parameters and said core temperature are estimated such that a difference is minimised between the temperatures indicated by the sensor elements, and the temperatures resulting from the dynamic model at said first and second sensor elements for a plurality of time points which lie temporally prior to a specific time point. An estimated core temperature where this difference has been minimised is the core body temperature to be determined. |
