Abstract:
1. An arrangement for measuring the body temperature of a living organism, the arrangement comprising: a housing; a first sensor mounted in said housing and disposed in contact engagement with the skin of the living organism for measuring a first temperature; a second sensor mounted in said housing for measuring a second temperature; said first sensor having a side facing away from said skin; said second sensor being mounted at a distance from said side of said first sensor; insulating means disposed between said first and second sensors for thermally insulating said first and second sensors from each other and conducting a thermal flow therebetween from which a thermal loss flow (q compensation means for determining or estimating said thermal loss flow (q an evaluation unit operatively connected to said compensation means so as to permit consideration of said thermal loss flow (q wherein said evaluation unit determines said body temperature with the aid of a formula and said compensation means is a compensation term which expands said formula; wherein said housing has an outer wall; and, said compensation term is dependent upon at least one of a boundary temperature (t said arrangement further comprising a third sensor mounted in the region of said outer wall for measuring said boundary temperature and said compensation term being formed in dependence upon said boundary temperature (t wherein said compensation term is formed exclusively by coupling of constant parameters (K wherein: K K K A A t 14=said compensation term; and, wherein, said constant parameter (α) is a thermal conductance constant (α) representing the thermal conductance between said outer wall of said housing and the ambient (U).
