Systems and methods for determining patient temperature

摘要

A temperature probe includes a handle and a shaft extending from the handle. The shaft includes a distal end, a proximal end, and a tip at the distal end. The temperature probe also includes 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. The temperature probe further includes a temperature sensor disposed on the shaft, the temperature sensor configured to measure a body cavity temperature of a patient.

1. A temperature probe, comprising:
a shaft having a distal end, a proximal end, and a tip at the distal end; a first sensor disposed on the shaft, the first sensor configured to measure a capacitance value associated with a measurement site of a patient, and to generate a first signal, based on the capacitance value, indicative of at least one of a proximity to the measurement site and an identity of the measurement site; a second sensor disposed on the shaft, the second sensor configured to generate a second signal indicative of a temperature associated with the measurement site; and a controller in communication with the first and second sensors, the controller configured to:
receive the first and second signals,determine a difference between the capacitance value and a known capacitance value, anddetermine a core temperature of the patient based on the difference and the second signal.
