Abstract

<P>PROBLEM TO BE SOLVED: To provide a pulse rate measuring instrument capable of easily measuring a pulse rate in a short time in a medical examination or the like. <P>SOLUTION: This pulse rate measuring instrument is provided with a time measuring part 2 for measuring time T measured from the first pressing of an input key 1 to the last pressing of the input key 1 by pressing the input key 1 every time an examiner senses the pulse or heart beat of a subject; an input frequency measuring part 3 for measuring the frequency N of pressing the input key 1; an arithmetic part 4 for computing a pulse rate from the measured time T and the frequency N immediately at every pressing of the input key 1; and a display part 5 for displaying the pulse rate obtained by computation, at every pressing of the input key 1. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention is for easily measuring a pulse rate in medical treatment or the like.
[0002]
[Prior art]
When a doctor, a nurse, or the like measures the pulse rate of a subject in daily medical care, the pulse rate of the subject is palpated by palpation, and the heart rate is measured for one minute while watching a clock.
[0003]
[Problems to be solved by the invention]
In daily medical care, in subjects without arrhythmia, measuring the pulse rate for one minute is not often performed due to a time problem. Usually, the pulse is counted for 30 seconds and the number is doubled, or the pulse is counted for 15 seconds and the number is quadrupled, but there is a problem that accuracy is reduced in a short measurement. In addition, a clock capable of measuring seconds was required for the measurement.
[0004]
[Means for Solving the Problems]
According to the present invention, each time the examiner senses the pulse or heart rate of the subject, by pressing the input key, the pulse rate is immediately calculated from the number of times the input key is pressed and the measurement time, and the displayed pulse rate is displayed. It is a measuring instrument.
[0005]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a circuit configuration diagram of a pulse rate measuring device according to an embodiment of the present invention. Each time the examiner senses the subject's pulse or heartbeat, the input key 1 is pressed to measure the time T measured from the first press of the input key 1 to the last press of the input key 1. A unit 2, an input number measuring unit 3 for measuring the number N of times the input key 1 is pressed, and a calculating unit 4 for calculating a pulse rate from the measured time T and the number N immediately each time the input key 1 is pressed; This is a pulse rate measuring device including a display unit 5 for displaying the pulse rate obtained by the calculation each time the input key 1 is pressed.
[0006]
The pulse rate can be obtained by dividing a value obtained by subtracting 1 from the number N of times the input key 1 is pressed, by a measurement time T from when the input key 1 is first pressed to when the input key 1 is last pressed. In addition, if the input key 1 is pressed and an electronic sound is emitted when a signal is input to the time measuring unit 2 and the input count measuring unit 3, a measurement error can be prevented.
[0007]
【The invention's effect】
If the pulse rate measuring device of the present invention is used, a clock that has been used conventionally becomes unnecessary, and a relatively accurate pulse rate can be measured easily and in a short time.
