Systems and methods for determining patient temperature

A method of manufacturing a medical device, comprising:

• providing a shaft having a distal end and a proximal end;
• connecting a first sensor to the shaft, the first sensor configured to:
• determine a change in an amount of radiation received by the first sensor as the first sensor approaches a measurement site, and
• generate a first signal indicative of the change in the amount of radiation;
• connecting a second sensor to the shaft, the second sensor configured to generate a second signal indicative of a temperature associated with the measurement site;
• and
• operably connecting the first sensor and the second sensor to a controller, the controller configured to:
• receive the first signal,
• receive the second signal,
• determine an identity of the measurement site based at least in part on the change in the amount of radiation,
• select, based on the identity of the measurement site, an operating mode of the medical device associated with estimating a core temperature of a patient based on the second signal, and
• based on the selecting, cause the medical device to operate in the operating mode.

A medical device, comprising:

• a shaft having a distal end and a proximal end;
• a first sensor disposed on the shaft, the first sensor configured to:
• determine a change in an amount of radiation received by the first sensor caused by a probe cover being at least partly disposed on the shaft, and
• generate a first signal indicative of the change in the amount of radiation;
• 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 sensor and the second sensor, the controller configured to:
• receive the first signal,
• receive the second signal,
• determine a thickness of the probe cover based at least in part on the change in the amount of radiation indicated by the first signal,
• select an operating mode of the medical device, the operating mode being configured for use in estimating a core temperature of a patient, with the probe cover disposed on the shaft, and based on the second signal, and
• based on the selecting, cause the medical device to operate in the operating mode.

• generate a first signal indicative of the change in the amount of radiation;
• 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 of the patient;
• and
• a controller in communication with the first sensor and the second sensor, the controller configured to:
• receive the first signal,
• receive the second signal,
• determine an identity of the measurement site based at least in part on the first signal,
• select, based on the identity of the measurement site, an operating mode of the temperature probe associated with estimating a core temperature of the patient based on the second signal, and
• cause the temperature probe to operate in the operating mode.
