Vorrichtung zur Temperaturüberwachung

摘要

An apparatus for monitoring body temperature includes a transmitter unit for insertion into a body cavity and a physically separate receiver unit. The transmitter unit includes a housing 10 containing a thermistor TH1 and a radio transmitter 12 for transmitting a radio signal in which variations in the resistance of the thermistor are encoded as a modulation of the signal eg by varying the interpulse interval of a pulse train. The receiver unit has a radio receiver for detecting and demodulating the radio signal.
