A temperature sensing device intended to be placed into a body orifice or on the body surface, and used in conjunction with a separate parent device with a display (e.g., electronic patient thermometer, infant warmer) to enable measurement/monitoring of a patient’s temperature; its use is not dedicated to a specific type of procedure. It is typically constructed of flexible materials (e.g., plastic or rubber) with a metal conducting core; the distal end of different device types will be designed for a particular application site. This is a single-use device.
