Abstract:
1. A thermometry apparatus for determining a temperature of a body that includes: a temperature sensing probe that further includes an elongated shaft having a proximal end and a distal end; a tip member secured to the distal end of said shaft, said tip member containing an inner shell and an outer shell that are separated by a space, said shells being fabricated of a material having a high heat transfer coefficient; a heating element that is mounted upon the outer surface of the inner shell; a heat sensor that is also mounted upon the outer surface of the inner shell; electrical leads connected to said heating element and to said heat sensor; a thermally conductive material filling said space between said shells; and wherein said inner shell contains a first pair of thick film electrical traces extending along the outer surface of said inner shell, said first pair of electrical traces being arranged to electrically couple said heater to a first pair of electrical leads.
