    Abstract: A finger probe 10 for use with an oximeter includes an upper housing 20 and a lower housing 22 pivotably hinged together at their distal ends 12 such that a human finger can be inserted into the proximal end 14 of the finger probe into a chamber 26 formed therebetween. The probe 10 contains at least one light emitter 50 and at least one light detector 38 situated within the upper and lower housings so as to allow light from the emitter 50 to pass through the finger to the detector 38. At least one emitter 50 is contained within an emitter housing 42 that is pivotably mounted to the upper housing 20 such that it conforms to the shape of the patient's finger when inserted into the chamber 26. Also, wiring 16 for the emitter 50 and detector 38 depends outwardly from the proximal end 14 of the finger probe along the finger such that the wiring can be readily taped to the finger and, thus, help retain the finger probe 10 in position on the finger.

    Abstract: Disclosed is a blood pressure measurement apparatus in which a waveform discrimination method is used in the recognition of Korotkoff sounds in the measurement of blood pressure by auscultation. In processing executed by the apparatus, the minimum point or maximum point (C3) of a signal waveform indicative of the sound or vibration produced by a blood vessel is detected, and a maximum value or minimum value point (C2) is detected within a predetermined time region (t,) the final instant of which is the point (C3). If a level difference between the point (C2) and the point (C3) is within a predetermined range, there is detected a minimum value or maximum value point (C1) within a predetermined time region (t2) the final instant of which is (C2). If a level difference between the point (C1) and the point (C2) is within a predetermined range, there is detected a maximum value or minimum value point - (C4) within a predetermined time region (t3) the starting instant of which is the point (C3). It is then discriminated whether a level difference between the point (C4) and the point (C3) falls within a predetermined range. Control proceeds in successive fashion when each of these conditions is satisfied, with a Korotkoff sound being recognized in the signal waveform when all of these conditions are satisfied.

    Abstract: The present invention relates to a system for measuring from the outside a pressure within the heart in a living body or a pressure in a body of the industrial field which does not allow measurement by directly inserting a pressure measuring sensor. This system provides a method of measuring a pressure of the object by generating fine bubbles through cavitation by applying a low frequency ultrasonic wave and by detecting such generation with high of low harmonics frequency due to the bubbles or a higher frequency ultrasonic wave applied from outside.

    Abstract: A method and apparatus for determining the rate of flow of a liquid in a region of a body using a nuclear magnetic resonance technique. Nuclear magnetic resonance is excited firstly preferentially in a slice (43) of the body which includes the region and then over the whole of the body. A period of time ( T ) is allowed to elapse, and nuclear magnetic resonance is then excited preferentially in the slice. The free induction decay signal is then measured, and the signal is related to the state of flow of the liquid through the slice (43).

    Abstract: A heart rate monitor device suitable for use in monitoring aerobic exercise training, automatically calculates a fitness parameter for a subject by monitoring the subject's heart rate and pacing the subject through a submaximal exercise stress test protocol. A microprocessor in the device is fed data peculiar to the individual subject, and then generates pacing signals to produce audible tones or beeps. The stride frequency, or rate of the tones varies at intervals so that the subject can exercise by running at progressively faster speeds. At the point of exhaustion, or maximum heart rate, the subject's maximal oxygen uptake capacity is calculated, based on the elapsed time, and is displayed as a fitness parameter. The subject's exercice level is automatically monitored based on his or her exercise heart rate, maximum heart rate, and rest heart rate.

    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.
