Wireless disposable physiological sensor

摘要

A patient physiological parameter monitoring apparatus for a subject includes a sensor assembly having at least one responsive element that produces a first signal upon detection of a change in temperature. The assembly also includes a converter for converting the first signal into an electrical signal, and a transmitter for wirelessly transmitting converted electrical signals upon demand based upon receipt of a transmitted signal from an interrogation device. Preferably, at least a portion of the sensor assembly is disposable to permit single use or single subject use and can be further used to track location and information of medical equipment in addition to subjects.
