Abstract

A noninvasive physiological sensor includes electrical isolation to isolate the patient and the sensor electronics from potentially harmful electrical surges.

Claims

1. A noninvasive physiological sensor including isolation to protect a patient from potentially harmful electrical events, the physiological sensor comprising:

an input configured to receive drive signals from a patient monitoring device;

an output configured to communicate a noninvasively detected signal representative of a physiological parameter to the patient monitoring device; and

an isolation element in communication with the input configured to isolate a patient from potentially harmful electrical events.

2. The sensor of claim 1, further comprises a memory element configured to communicate with the patient monitoring device.

3. A noninvasive physiological sensor including isolation to protect sensor electronics from potentially harmful electrical events, the physiological sensor comprising:

an input configured to receive drive signals from a patient monitoring device;

an output configured to communicate a noninvasively detected signal representative of a physiological parameter to the patient monitoring device; and

an isolation element in communication with the input configured to isolate sensor electronics from potentially harmful electrical events.

4. The sensor of claim 3, further comprises a memory element configured to communicate with the patient monitoring device.
