Embodiment approach 1
[0088] The biological information measurement device according to Embodiment 1 will be described based on the drawings.
[0089] Such as figure 1 As shown, the biological information measurement device 1 is used to measure the state of the subject when he is at rest and when he is performing a weight exercise using the exercise stress device A, and obtain various information about the body.
[0090] Body information measuring device 1 such as figure 2 As shown, it includes an ECG collection device 2 , a heart sound collection device 3 , a heart rate collection device 4 , a control device 5 , a display device 6 and a printing device 7 .
[0091] ECG acquisition device 2 such as image 3 As shown in (A), it can be formed by measuring electrodes 21 , amplifying means 22 and AD converting means 23 . The measurement electrodes 21 are two terminals for collecting, as electrocardiographic signals, potentials generated in the body of the subject when the heart pulsates. Amplifyin...
Embodiment approach 2
[0170] The biological information measurement device 10x according to Embodiment 2 of the present invention is a device characterized by obtaining the heart rate from the R wave or the first heart sound. again, in Figure 11 in, where and figure 2 Those having the same configuration are assigned the same reference numerals and their descriptions are omitted.
[0171] set at Figure 11 The heart rate counting device 509x in the control device 5x of the shown biological information measuring device 10x measures the interval P1 between the R wave detected by the reference timing detecting device 503 and the next R wave (refer to Figure 5 ) to count the heart rate.
[0172] In addition, the heart rate counter 509x can count the heart rate based on the first heart sound S1 detected by the first heart sound detection device 505 according to the interval P1.
[0173] In this way, based on the R wave and the first heart sound measured during the exercise intensity measurement, b...

Abstract
Provided are a somatic data-measuring apparatus that can easily and accurately measure the optimal exercise intensity for the subject being measured, and a somatic data measurement method. The somatic data-measuring apparatus (1) is provided with a heart sound-acquiring means (3) that detects the subject's heart sounds and outputs same as heart sound data, a first heart sound-extracting means (51) that detects the first heart sound on the basis of the heart sound data, a first heart sound amplitude-measuring means (506) that measures the amplitude from the detected first heart sound and outputs same as first heart sound amplitude data, a heart rate-counting means (509) that measures the subject's heart rate and outputs same as heart rate data, and an exercise intensity-computing means (510); that computes the double product of the heart rate data and the first heart sound amplitude data as double product data and detects, as the optimal exercise intensity, the exercise intensity at which the approximation line, which approximates said double product data distribution, bends. Since the double product, which represents myocardial oxygen consumption, is effective as an index that accurately reflects the state of cardiac workload, it is possible to measure accurately the degree of workload on the heart.
Description
technical field [0001] The present invention relates to a technique for measuring various kinds of body information such as information on the heart and information on exercise intensity. Background technique [0002] Health maintainers, obese people, and people with metabolic disorders walk or jog in order to improve their condition. In addition, in exercise therapy for patients with myocardial infarction, hypertension, etc., load exercise is performed for rehabilitation training. [0003] If the load (intensity) of the load exercise is insufficient, it will be difficult to obtain the effect, and the excessive load may have adverse effects on the body. Therefore, it is desired to find out the best optimal exercise intensity for each subject. [0004] The techniques described in Patent Documents 1 and 2 are known as techniques related to optimal exercise intensity. [0005] The method of determining the optimal exercise intensity described in Patent Document 1 is to carry...
