    摘要： A vital sign measurement device includes a sensor fixation device, an optical sensing system, and an output unit. The sensor fixation device is adapted to be placed against an anatomical location of a subject, within which is an artery. The optical sensing system includes an optical source, an optical refractor, and an optical detector, all of which are held by the sensor fixation device and move with movement of the sensor fixation device. The optical sensing system is positioned with respect to the sensor fixation device to sense movement corresponding to an arterial pulse when the sensor fixation device is placed against the anatomical location of the subject. The optical sensing system can sense an arterial pulse from the movement, bending, or compression of at least one portion of the optical sensing system relative to other portions of the optical sensing system resulting in a change in an optical signal received by the optical detector. The output unit receives, from the optical sensing system, an input indicative of movement corresponding to an arterial pulse and generates, using the input, a measure of the vital sign.

    摘要： A method of obtaining information that corresponds to the R—R interval of electrocardiogram from the pulse-wave of a human body. The method is comprised of steps of detecting the pulse-wave of a human body in a predetermined period, differentiating the detected pulse-wave to provide a speed-pulse-wave, measuring intervals of peaks of the speed-pulse-wave, and substituting the intervals of peaks of the speed-pulse-wave for the R—R interval of the electrocardiogram.

    摘要： A pulse wave analysis device for analyzing the condition of a human body is disclosed. A cuff band is wrapped around the tip of the second finger of a subject's hand. When the operator depresses the beginning-of-measurement key, the finger tip is pressed at various pressures by means of an air pump and a pressure sensor. Pulse wave signals at different pressure values are automatically measured by an optical fingertip plethysmogram sensor. The signals are transmitted to a CPU through a BPF, an amplifier, and an ADC. The CPU performs FFT analyses on the signals and determines to which pattern from among the patterns stored in a ROM the pattern level of the pulse wave spectrum for a given pressure value is closest, and displays the result on a display unit as a test result indicating the viscoelasticity of the subject's peripheral circulation tissue.

    摘要： An apparatus for measuring arterial elasticity includes a cuff member having a light source and light detector, a variable pressure generating device, a fluid pressure sensor, a digital signal processor and a difference detecting element. The fluid pressure in a fluid pressure chamber in the cuff member is varied by a variable fluid pressure generating device. The digital signal processor responds to the output of the fluid pressure sensor and the output of the difference detecting element and delivers a digitally processed signal corresponding to an arterial volume change based on a simulated arterial elasticity. The arterial elasticity and the frequency characteristic thereof are derived based on the operation of the digital signal processor.

    摘要： A non-invasive method and apparatus for sensing relative blood flow to extremities, such as using photoelectric dermachromography to measure differential blood flow between extremities, for the purpose of diagnosing cardiovascular conditions, employs reflective colorimeters for performing comparative light reflection rheology (LRR) on blood flow to the extremities. The resting, steady-state LRR for both the left and right palms are simultaneously measured when both arms are in a raised, steady-state condition, and again when both arms are in a lowered, steady-state condition, thereby providing a repeatable measurement of overall vasomotor tone, the tone of the smooth muscles of the arterial walls. Two portable light gauges are used, each including a plurality of light sources such as light-emitting diodes (LEDs) arranged around at least one light detector. Each gauge is removably attachable to the palms of the hands of the patient whose vasomotor tone is to be determined. The gauges are removably attached to the palms so that the hands are movable, and measurements are taken while the left and/or right hands are in a raised, substantially steady-state UP condition, and then again while the left and/or right hands are in a lowered, substantially steady-state DOWN condition. After a series of these UP and DOWN measurements are taken, the gauges are switched and another series of UP and DOWN measurements with the reversed gauges are taken. Each gauge is independently calibrated by using standardizing reference scales.

    摘要： An inflatable cuff is disclosed for encircling a patient's finger and which includes a light source and a light detector constructed in a way to detect the movement, or lack of movement, of arterial passages within the finger. The cuff is comprised of an inflatable bladder that contacts the patient finger; having a tubing provided for inflation and deflation of the bladder. Surrounding the external surface of the bladder from the finger is a metalized backing that covers and shields the inflatable bladder. A flexible circuit is affixed to the metalized backing and to which is attached the light source and light detector and which further includes wiring from the light detector and light source to a connector at its distal end for connection to further circuiting. Further, surrounding the flexible circuit is a electrical and light shielding and label that covers the flexible circuit and which provides shielding as well as a means of affixing the inflatable cuff to the patients finger. The overall cuff is readily manufacturable and particularly adapted for its specialized use.
