INTEGRATED SENSOR FOR BODY TEMPERATURE, PULSE AND BLOOD PRESSURE

摘要

PURPOSE:To compare a body temp., pulse and blood pressure with reference values and to show the normal/defective condition thereof by memorizing the reference values, automatically and arithmetically processing the measured values to promptly compare the values with the reference values and displaying whether the body temp., pulse and blood pressure are within the ranges of the respective normal values or not. CONSTITUTION:The output from the sensor 3 is amplified by an amplifier 10 and is compared with the output voltage of a memory part 12 set at 37 deg.C body temp. by a comparator 11. A display diode 5 or 6 is displayed by the blood pressure voltage. The pulse signal (pulse sensor) consisting of a miniature microphone, etc., is amplified by pushing a pulse switch 8. The number of the pulses for, for example, 30 seconds, is added in an arithmetic part 13 and is compared with the signal from a memory 15 for the pulses of general ordinary persons in a comparator circuit 14. The normal or abnormal condition is lighted and displayed by the light emitting diode 5 or 6. A pulse sensor 4 is operated and the bracelet of a driving part for measuring the blood pressure of 2 is clamped when a blood pressure switch 9 is pushed. The max. blood pressure or min. blood pressure is emitted from the driving part 16 by the signal from a signal generating part 13 when the output of the amplifier 10 attains a prescribed signal. The normal or abnormal condition is displayed on the light emitting diode 5 or 6 by the voltage of a max. blood pressure and min. blood pressure memory 18 and the signal from a comparator circuit 17.
