摘要： A method and apparatus for improving the calculation of oxygen saturation and other blood constituents by non-invasive pulse oximeters. The method and apparatus permit more accurate determination of blood flow by collecting time-measures of the absorption signal at two or more wavelengths and processing the collected time-measure to obtain composite pulsatile flow data from which artifacts have been filtered. The processing may occur in the time domain or in the frequency domain. In the preferred time domain embodiment, successive portions of periodic information are weighted and added together in synchrony to obtain the composite pulse information. In the preferred frequency domain embodiment, the time-measure in Fourier transformed into its spectral components to form the composite information. A new method and apparatus for correlating the heartbeat and optical pulse is provided whereby a product of the ECG R-wave and optical pulse signals corresponding to the same heartbeat is obtained, and one signal is time shifted relative to the other until a maximum waveform product corresponding to the heartbeat is determined.

摘要： A noise controller for use in a probe in a hand held ultrasonic Doppler fetal heart beat detection and monitoring system where the probe includes a crystal for generating an input signal as a function of the ultrasonic energy in received ultrasonic wave and a detector for generating a first signal from the input signal. The noise controller comprises a volume controller for receiving the first signal and for processing the first signal to produce an analog signal as the output of the probe. A detector generates a second signal whenever break noise is detected in the first signal. A muting circuit immediately lowers the amplitude of the analog signal upon detection of break noise by the detector thereby substantially attenuated in the analog signal the break noise which occurred in the first signal.

摘要： Doppler Ultrasound techniques have been used for many years to measure the flow rate of fluids. One of the challenges in using these techniques is to separate fluid flow signal from background noise. The present invention is directed to methods and apparatus for automatically distinguishing fluid flow signal from noise. It is found that noise in Doppler ultrasound techniques has characteristic of a white Gaussian spectral distribution and the mean noise can be characterized as a constant. The present invention involves measuring ultrasonic signals, generating sets of discrete spectral components from these signals, and statistically determining a maximum likelihood estimation from the spectral components. This estimation is used to calculate the fluid velocity.

摘要： A transcranial Doppler (TCD) probe fixation assembly is provided comprising an assembly for holding a TCD probe. The probe holding assembly comprises in one embodiment a track assembly and in another embodiment a single bar assembly. The ends of both the track assembly and bar assembly are connected to an annular member. Strap retaining members are provided on the exterior of the annular member for strapping the TCD probe to a patient's head. In use, the position of the probe is selected by moving the probe linearly along the track and bar assemblies and by rotating the track and bar assemblies relative to the annular member. Thereafter, the probe is angulated until a desired signal is obtained, at which point it is locked in place.
