PHYSIOLOGICAL SENSOR

摘要

A sensor used to measure physiological characteristics of body tissues is provided. The physiological sensor includes a first light source assembly having a first light source in parallel with a second light source. Each of the first light source and the second light source have an anode and a cathode. A second light source assembly includes a third light source in parallel with a fourth light source. Each of the third light source and the fourth light source have an anode and a cathode. The anode of the first light source is electrically connected to the cathode of the second light source, the anode of said third light source, and the cathode of said fourth light source. The anode of the third light source is electrically connected to the cathode of the fourth light source.

主权项

1. A system, comprising:
a first light source assembly disposed on a sensor pad at a first location, wherein the first light source assembly comprises a first plurality of light sources configured to emit light into a body tissue; a first detector spaced a first distance apart from the first light source assembly on the sensor pad, wherein the first detector is configured to detect the emitted light; a second detector spaced a second distance apart from the first light source assembly on the sensor pad along an imaginary axis connecting the first light source assembly and the first detector, wherein the second detector is configured to detect the emitted light, and wherein the first light source assembly, the first detector, and the second detector are configured for cerebral or tissue oximetry; and a second light source assembly disposed on the sensor pad at a second location, wherein the second location is offset from the imaginary axis and closer to the first and second detectors than the first location, wherein the second light source assembly comprises a second plurality of light sources configured to emit light into the body tissue, and wherein the second light source assembly and one or both of the second detectors are configured for pulse oximetry.
