WIRELESS PHYSIOLOGICAL MONITORING
First Claim
1. A wireless physiological monitoring system for measuring physiological signals from a patient, comprising:
- a monitoring device having a first transceiver;
at least one wireless sensor disposed on a measurement site on the patient for measuring a physiological signal, the at least one wireless sensor having a second transceiver for transmitting a corresponding wireless physiological signal to the first transceiver; and
at least one wireless stimulator having a third transceiver, the at least one wireless stimulator being adapted to provide a stimulation current to the patient in response to at least one of a command signal transmitted by the first transceiver of the monitoring device and manual actuation.

Abstract
Embodiments of the invention relate to a wireless physiological monitoring system. The system includes at least one wireless sensor and a monitoring device which are linked to one another of a wireless fashion for measuring physiological signals of a patient. The at least one wireless sensor is located on the patient and may comprise a wireless surface electrode assembly or a wireless needle assembly. The system may also comprise a wireless stimulator synchronized with the wireless sensor for performing certain diagnostic tests, such as nerve conduction velocity tests, for example. The wireless sensor preferably includes active, reference and common conductors. The common conductor can be used to measure the common mode voltage of the patient in the vicinity of the testing, and this voltage can then be subtracted from the measured active and reference voltages.
