Abstract:
1. A temperature probe, comprising: a handle; a shaft extending from the handle, the shaft having a distal end, a proximal end, and a tip at the distal end; a capacitance sensor disposed on one of the handle and the shaft, the capacitance sensor configured to measure a change in capacitance when positioned proximate a conductor; a temperature sensor disposed on the shaft, the temperature sensor configured to measure a body cavity temperature of a patient; and a controller in communication with the temperature sensor and the capacitance sensor, wherein the controller is configured to determine a patient temperature based on a) the body cavity temperature, and b) a difference between a first capacitance measured by the capacitance sensor and a known capacitance stored in a memory associated with the controller.
