    • A blood constituent monitoring method for inducing an active pulse in the blood volume of a patient. The induction of an active pulse results in a cyclic, and periodic change in the flow of blood through a fleshy medium under test. By actively inducing a change of the blood volume, modulation of the volume of blood can be obtained to provide a greater signal to noise ratio. This allows for the detection of constituents in blood at concentration levels below those previously detectable in a non-invasive system. Radiation which passes through the fleshy medium is detected by a detector which generates a signal indicative of the intensity of the detected radiation. Signal processing is performed on the electrical signal to isolate those optical characteristics of the electrical signal due to the optical characteristics of the blood.
    • 一种用于在患者的血液体积中诱导活性脉冲的血液成分监测方法。 活性脉冲的诱导导致血液通过待测肉质培养基的循环和周期性变化。 通过积极地引起血液量的变化,可以获得血液体积的调节以提供更大的信噪比。 这允许以非侵入性系统中先前可检测的浓度水平检测血液中的成分。 通过肉质培养基的辐射由产生指示检测到的辐射强度的信号的检测器检测。 对电信号执行信号处理,以隔离由于血液的光学特性引起的电信号的这些光学特性。
