An assembly of devices designed to continuously measure and wirelessly transmit a patient's core and/or skin temperature to a receiving location (e.g., central station, bedside monitor) for viewing. It typically consists of a portable radio transmitter and skin, tympanic, rectal, oesophageal, and/or ingestible temperature sensors that are attached to the patient; and a bedside or central station receiver which detects the radio waves and displays and/or processes the temperature values using computing capabilities. The device is used mainly to evaluate the physiologic status of persons under or after severe physical stress and/or effort.
