Assignee: WELCH ALLYN, INC.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 16:
17. A method of manufacturing a temperature measurement device, comprising:
providing a first sensing element, comprising a thermistor, configured to detect an ambient temperature of an environment;
providing a second sensing element, comprising an infrared temperature sensing element, configured to detect a patient temperature of a patient;
associating a controller with at least one of the first sensing element and the second sensing element; and
programming the controller to determine a core temperature of the patient based on determining a first rate of change of the ambient temperature over a first time period, determine a second rate of change of the patient temperature over a second time period that at least partially overlaps the first time period, determine a threshold rate of change, select a first correction factor based at least in part on determining that the first rate of change exceeds the threshold rate of change, determine the core temperature of the patient based at least in part on applying the first correction factor to the second rate of change of the patient temperature in response to the first rate of change exceeding the threshold rate of change, selecting a second correction factor based at least in part on determining that the first rate of change is less than the threshold rate of change, and determining the core temperature of the patient by applying the second correction factor based at least in part on determining that the first rate of change is less than the threshold rate of change.
