Systems and methods for determining patient temperature

摘要

A temperature probe includes a shaft having a distal end, a proximal end, and a tip disposed at the distal end. The probe also includes an infrared sensor configured to measure a temperature of a structure disposed proximate the shaft. The probe further includes a temperature sensor disposed distal to the infrared sensor. The temperature sensor is configured to measure a body cavity temperature of a patient.

1. A system, comprising:
a shaft having a central longitudinal axis, a distal end, a proximal end, and a substantially atraumatic tip disposed at the distal end of the shaft, the shaft defining a distal end of a temperature probe; a handle disposed at the proximal end of the shaft and defining a proximal end of the probe; a thermopile embedded substantially within the shaft and configured to measure a temperature of a probe cover removably connectable to the shaft by receiving radiation passing from the probe cover to the thermopile in a direction substantially transverse to the longitudinal axis; a temperature sensor disposed distal to the thermopile and embedded substantially within the shaft, the temperature sensor comprising at least one of a thermocouple or a thermistor configured to measure a body cavity temperature of a patient; and a controller operably connected to the thermopile and the temperature sensor, the controller being configured to determine a core temperature of the patient based at least partly on a first input received from the thermopile indicative of the temperature of the probe cover, and a second input received from the temperature sensor indicative of the body cavity temperature.
