Wireless disposable physiological sensor
First Claim
1. A wireless thermometer apparatus for measuring the body temperature of a subject, said apparatus comprising:
- a sensor assembly including at least one temperature responsive element, said element producing a first signal upon detection of a change in temperature, a converter for converting the first signal into an electrical signal, and a transmitter for wirelessly transmitting the converted electrical signal upon demand; and
an interrogation device having a transmitter which wirelessly transmits a trigger signal wherein said sensor assembly does not transmit readings of said temperature responsive element until the interrogation device transmits the trigger signal, and in which said sensor assembly is disposed on a patient to enable temperature readings to be taken without significant delay, wherein at least a portion of said sensor assembly is disposable.

Abstract
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.

27. Apparatus for measuring at least one physiological parameter of a subject, said apparatus comprising:
-
a sensor assembly including at least one physiological parameter responsive element, said responsive element producing a first signal upon detection of a change in physiological parameter, a converter for converting the first signal into an electrical signal, and a transmitter for wirelessly transmitting the converted electrical signal upon demand; and
an interrogation device having a transmitter which wirelessly transmits a trigger signal wherein said sensor assembly does not transmit readings of said physiological parameter responsive element until the interrogation device transmits the trigger signal, and in which said sensor assembly is disposed on a subject to enable temperature readings to be taken without significant delay, wherein at least a portion of said sensor assembly is disposable. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
