Isolation and communication element for a resposable pulse oximetry sensor
First Claim
1. An optical sensor configured to noninvasively monitor one or more physiological parameters of a wearer of the optical sensor, the optical sensor comprising:
- a plurality of emitters;
a detector configured to detect light attenuated by body tissue of a wearer of the optical sensor;
an emitter input configured to supply an emitter drive signal to the plurality of emitters;
a memory device; and
a communication device configured to receive sensor data to be stored in the memory device.

Abstract
A sensor has a connector adapted to electrically communicate with a physiological measurement instrument. A breakable conductor incorporated by the sensor transitions from a continuity state to a discontinuity state as the result of sensor wear. An isolation and communications element (ICE) has an instrument port and an electrically isolated loop port. The instrument port is in communications with the connector and the loop port is in communications with the breakable conductor. The ICE generates a control output responsive to the discontinuity state to render the sensor inoperable.
