Patent ID: 8315682

Claim:
A medical pulse oximetry sensor comprising: a carriage housing adapted to fit snugly about a portion of a subject's anatomy with a relatively high oxygenated blood throughput; a first light emitting diode mounted in the housing for emitting light in the electromagnetic spectrum of the red wavelengths; a second light emitting diode mounted in the housing for emitting light in the electromagnetic spectrum of the infrared wavelengths; an integrated CMOS semiconducting component chip mounted in the carriage housing which includes: at least one photodiode for detecting incumbent light from the first and second light emitting diodes after the emitted light has passed through a blood oxygenated portion of a subject and generating electrical signals indicative thereof; an amplifier for amplifying the signal from the at least one photodiode; a microprocessing unit for processing the amplified signals into at least one of pulse oximetry value and plethymographic waveforms; a light emitting diode control operationally connected to the microprocessing unit that controls light emissions from the first and second light emitting diodes; and a timing circuit that coordinates processing the signals generated by the photodiode and operations of the light emitting diodes.
