SYSTEM FOR RECORDING ELECTRONEUROGRAPHIC ACTIVITY

摘要

A system for recording electroneurographic activity comprising at least three electrodes capable of sensing a nerve signal from a peripheral nerve and means for receiving and processing the sensed nerve signal to identify a signal indicative of a specific action being a movement of a body part performed by the patient and for producing a control signal in response thereto featuring means for rejection of signals originating from biological interference sources without adversely affecting the electroneurographic activity being measured.

主权项

1. A system for recording electroneurographic activity, comprising:
at least three electrodes adapted to be arranged along a longitudinal nerve axis of a peripheral nerve; at least one device configured to amplify and process the sensed nerve activity and produce a control signal in response thereto; a digital adaptive filter configured to reject bioelectric interferences with overlapping frequency spectra; wherein a reference signal proportional to the bioelectric interferences is derived from measurements of a plurality of the at least three electrodes.
