Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a relaxation level detection device, more specifically, to a relaxation level detection device.
The present invention relates to a relaxation degree detection device that determines whether a person is mentally relaxed or tense.

[Background technology] In recent years, in a society that has become more complex, psychological and mental stress such as anxiety, dissatisfaction, anger, and irritability are increasing.
It has become necessary to exercise self-control so that these stresses can be quickly resolved and released without accumulating. In order to achieve this kind of self-control, we need to understand what a relaxed state is and what a tense state is, that is, recognize the degree of relaxation as a sensation and create that state. It is necessary to train people to feel this way, but each individual must acquire this feeling on their own, and it is difficult to obtain an objective guide, so there is a problem that it is difficult to get a real feeling even after training. be. Observing brain waves is the most accurate way to detect the degree of relaxation, but actually observing brain waves requires specialized knowledge, and is something that ordinary people can easily use. isn't it.

[Objective of the Invention 1 The present invention has been made in view of the above points, and its main purpose is to provide a relaxation level detection device that can be easily handled by the general public. .

[Disclosure of the Invention] (Structure) The relaxation level detection device according to the present invention includes a pulse wave detection unit that detects pulse waves in peripheral parts such as limbs, and a pulse wave detection unit that periodically integrates the level of the pulse wave in predetermined integration time units. an integrator circuit that stores the output value of the integrator circuit for each integration time, and a memory circuit that stores the output value of the integrator circuit for each integration time; a comparison circuit that compares the values and outputs a warning signal when the integral value output from the integration circuit is larger; and a display section that responds to the warning signal and displays that the patient is heading toward a tense state. This configuration allows the average person to easily and objectively distinguish between a relaxed state and a tense state.

(Example) First, the basic principle of the present invention will be explained.

In a relaxed state, the brain waves are as shown in Figure 2 (a
) - A wave with a relatively large amplitude of 8 to 13 Hz is obtained, as shown in Figure 2 (b) - A, and when there is something to worry about or in a tense state of irritability, the brain wave is as shown in Figure 2 (b) - A. 1
It is known that β waves with a relatively small amplitude of 3 to 30 Hz can be obtained. On the other hand, in the peripheral parts of the limbs, etc., when the body is relaxed, the blood vessels dilate, so a pulse wave with a large amplitude as shown in Figure 2 (a) - Mouth is obtained in response to alpha waves, and when the body is tense, the blood vessels dilate. Because the blood vessels constrict, a pulse wave with a small amplitude like the mouth in Figure 2 (b) corresponding to the β wave is obtained.6 Therefore, whether the brain wave is an A wave or a β wave depends on the pulse wave. It is thought that it corresponds to the amplitude, and it is thought that by detecting the level of the pulse wave, it is possible to determine whether the person is in a relaxed state or a tense state. In this way, since it is only necessary to determine the magnitude relationship between the pulse wave levels, as shown in Fig. 2(a) (
As shown in b)-7), if the pulse waves are integrated, the magnitude relationship between the amplitudes of the pulse waves can be easily identified.

A circuit configuration based on the above principle is shown in FIG.

Pulse waves are detected by the pulse wave detecting section 1 at peripheral parts such as hands and feet. The pulse wave detection section 1 has a conventionally well-known configuration in electronic blood pressure monitors and the like, and is configured to detect a pulse wave using a pressure sensor or a temperature sensor, and output an electrical signal corresponding to the pulse wave. The output of the pulse wave detector 1 is input to an absolute value circuit 2 and output as a signal with positive amplitude. That is, the zero-order integration circuit 3, which detects the level of the pulse wave, integrates the output level of the absolute value circuit 2 within a preset integration time. 8! When one integration in the unit of integration time is completed in the dividing circuit 3, the integral value is stored in the storage circuit 4,
At the same time, the integrated value is outputted to the comparison circuit 5 and compared with the integrated value at the previous integration time, which is already stored in the storage circuit 4. In the storage circuit 4, when a new integral value is stored, the previous stored value is erased, and the integral value is always updated to a new one. This operation is repeated periodically, and the integrator circuit 3
is reset and the integral value is deleted. In this way, the comparison circuit 5 compares the magnitude relationship between a pair of integral values adjacent in the time series at each cycle. Comparison circuit 5
Then, when the output value of the integrating circuit 3 is larger than the output value of the memory circuit 4, a warning signal is output to the display section 6 to indicate that the patient is heading toward a nervous state. That is, the level of the pulse wave is detected over time, and if the level is on the rise, it is determined that the patient is heading toward a nervous state.

As described above, when you are heading towards a nervous state, you will be shown this, and all you have to do is objectively recognize that you are heading towards a nervous state and train yourself to return to a relaxed state.

Here, the reason why the display is only performed when the patient is in a state of tension is because the state of tension does not last for a long time and the amplitude of the pulse wave becomes unstable. On the other hand, since a relaxed state can be maintained stably for a long time, the display section 6
This is because when the display is not performed, it can be determined that the person is relaxed.

[Effects of the Invention] As described above, the present invention includes a pulse wave detection unit that detects pulse waves in peripheral parts such as limbs, an integrating circuit that periodically integrates the level of the pulse wave in predetermined integration time units, A storage circuit that stores the output value of the integration circuit for each integration time, and a comparison between the integral value that is the output of the integration circuit and the integral value at the integration time one cycle before, which is stored in the storage circuit. It is equipped with a comparison circuit that outputs a warning signal when the integral value output from the integration circuit is larger, and a display section that responds to the warning signal and displays that the state is heading toward a nervous state. It is possible to distinguish between a tense state and a relaxed state by detecting pulse waves from the peripheral parts of the limbs, which are easier to detect. It has the advantage of being objectively identifiable. As a result, it has the advantage that it can be easily used for self-control of the autonomous god RI411 ¥1.
