Abstract: 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 occurs in the frequency domain. The time-measure is Fourier transformed into its spectral components to form the composite information.

Abstract: The oximeter for cooperation with an oximeter probe comprises decoding means responsive to encoded signals for selecting appropriate calibration coefficients for use in calculating oxygen saturation based upon the known wavelength of first and/or second light emitting means (10, 132 and 20, 130, resp.) in the probe.
A probe comprises a pair of light emitting means preferably diodes (10, 20, 130, 132) which emit light of narrow wavebands having known characteristic wavelengths through part of a patient onto a photosensor (30, 38). A coding means comprising resistor (40) of coded known resistance or else an eight bit connector (52′) is used to enable the oximeter to calculate the coefficient of extinction of the wavelengths of the LEDs. The resistor, LEDs and photosensor are mounted on self-attaching hook and eye tape (50) for mounting the probe onto the appendage of the patient. The probe is detachably wired to the oximeter, rendering the probe completely disposable. The oximeter is programmed at the factory to calculate the co-efficients of extinction of any LEDS which may be encountered in a series of disposable probes. From the co-efficients of extinction, the pulse rate and degree of arterial oxygen saturation is computed and displayed by the oximeter.Abstract translation: 用于与血氧计探头协作的血氧计包括解码装置，其响应于编码信号，用于基于第一和/或第二发光装置（10,132和20,130）的已知波长来选择用于计算氧饱和度的适当校准系数 。）在探针中。 探针包括一对发光装置，优选地，二极管（10,20,130,132）将通过患者的一部分的已知特征波长的窄波段的光发射到光传感器（30,38）上。 包括编码已知电阻的电阻器（40）或八位连接器（52分钟）的编码装置用于使血氧计能够计算LED的波长的消光系数。 电阻器，LED和光电传感器安装在自附钩和眼带（50）上，用于将探头安装到患者的附件上。 探头可拆卸地连接到血氧计，使探头完全一次性。 血氧计在工厂进行编程，以计算在一系列一次性探头中可能遇到的任何LEDS的消光系数。 从消光系数来看，脉搏率和动脉血氧饱和度由血氧计计算并显示。

Abstract: @ A pulse oximeter is disclosed of the type wherein light of two different wavelengths is passed through human or animal body tissue, such as a finger, an ear, the nasal septum or the scalp, so as to be modulated by the pulsatile component of arterial blood therein, and thereby allowing indication of oxygen saturation. The level of incident light is continually adjusted for optimal detection of the pulsatile component, while permitting accommodation to variable attenuations due to skin color, flesh thickness and other invariants. At significant slope reversal of the pulsatile component to negative (indicating a wave maximum), wave form analysis of blood flow occurs. A quotient of the pulsatile component of light transmission over the constant component of light transmission is measured for each of two wave lengths by direct digital tracking. The respective quotients are thereafter converted to a ratio, which ratio may be thereafter fitted to a curve of independently derived of oxygen saturation. Calibration is disclosed by solving four unknowns at at least four differing saturations. An output of pulse rate, pulse flow and oxygen saturation is given. An incident light source duty cycle is chosen to be at least 1 in 4 so that noise, inevitably present in the signal, may be substantially eliminated and filtered. Provision is made for a local battery-driven low power consumption instrument capable of being substantially independent of ambient light noise.
