Abstract
The present disclosure relates to a sensor for monitoring the depth of consciousness of a patient. The sensor includes a plurality of light sources, light detectors, and in some embodiments, electrodes. In an embodiment, the sensor includes reusable and disposable portions.
Claims22
A forehead sensor for monitoring the depth of consciousness of a patient comprising:
- a brain oxygenation sensor that includes at least one light source and two detectors;
- an EEG sensor that includes electrical leads that make contact with the skin of the patient's forehead;
- a reusable portion that houses the light source and detectors of the brain oxygenation sensor;
- and
- a disposable portion that houses a plurality of EEG electrodes and is removably connectable to the reusable portion.
2 more elements
A system for monitoring the depth of consciousness of a patient comprising:
- a forehead sensor that includes a brain oxygenation sensor;
- and
- a conventional pulse oximeter loaded with software for displaying data related to the blood oxygenation level of the brain cavity data processed by the forehead sensor.
A light source for a brain oxygenation sensor comprising:
- a substrate;
- emitters attached to the substrate for emitting light with at least two different wavelengths;
- a detector for detecting emitted light before it is attenuated by tissue;
- a cap connected to the substrate and
- an aperture for the emitted light to exit the light source and enter the tissue sight.
2 more elements
A connector providing communication between an optical sensor and a monitoring instrument, the connector comprising:
- a housing;
- and
- a processing board including a signal processor configured to drive a plurality of emitters and receive a detector signal responsive to light attenuated by brain tissue;
- said processor also configured to process said detector signal, said housing of said connector housing said processing board.
