摘要： Multi-wavelength photon density wave medical systems, methods, and devices are provided. In one embodiment, a multi-wavelength photon density wave patient monitor includes multiple light sources, a driving circuit, a fiber coupler, a sensor cable connector, a wavelength demultiplexer, detectors, and data processing circuitry. The driving circuit may modulate the light sources to produce several single-wavelength input photon density wave signals, which the fiber coupler may join into a multi-wavelength input signal. The sensor cable connector may provide this multi-wavelength input signal to a sensor attached to the patient and receive a multi-wavelength output signal. The wavelength demultiplexer may separate the multi-wavelength output signal into single-wavelength output signals for detection by the detectors. Based on a comparison of one of the single-wavelength output signals to a corresponding one of the single-wavelength input signals, the data processing circuitry may determine a physiological parameter of the patient.

摘要： Multi-wavelength photon density wave medical systems, methods, and devices are provided. In one embodiment, a multi-wavelength system may include a sensor, a sensor cable, and a patient monitor. The sensor may have an emitter output and a detector input configured to pass a multi-wavelength photon density wave input signal into a patient and receive a resulting multi-wavelength photon density wave output signal. The sensor cable may couple to the sensor using two optical cables for transmitting and receiving the multi-wavelength photon density wave signals. The patient monitor may couple to the sensor cable and generate several time-division multiplexed single-wavelength input signals by modulating one or more light sources at a frequency sufficient to produce resolvable photon density waves. By combining the several time-division multiplexed single-wavelength input signals into one of the optical cables of the sensor cable, the patient monitor may generate the multi-wavelength photon density wave input signal.
