The pulse sensor of the ECG type is configured to electrically measure the vibration of the blood flow of the patient by placing an electrode on the chest of the subject.

However, the ECG pulse type as described above was very uncomfortable because it measures the pulse while wearing the ECG sensor to compress the chest. Because the subject to measure the pulse during exercise or during the daily life has to wear and measure the halter on the waist, it was cumbersome to measure the pulse and inconvenient to work.

In addition, the conventional pulse instruments have been developed for the purpose of measuring the pulse of a patient in the flow of information in one direction, and no two-way devices have been developed to respond in any way to the measured data of the subject's pulse.

In particular, there was no study on the devices that can be treated immediately by determining that the subject's pulse is relatively good and slightly out of the normal value, that is, when the risk is rather low.

When it is determined that the pulse data of the subject determined as described above is in a normal state, that is, a safe state, the pulse of the subject is continuously measured.

However, if the pulse data of the subject determined as described above is determined to be in an abnormal state, i.e., unstable, it is pre-stored in the controller 30 to restore the pulse of the subject to a normal state according to the degree of instability. The treatment sound source file is sent out through the treatment sound source file sending unit 31, and the pulse of the subject is continuously measured.

That is, the control unit 30 determines the pulse risk of the subject to provide the treatment sound source file previously stored in the treatment sound source file transmitting unit 31 according to the risk, and the treatment sound source file transmitted as described above. Is provided to the subject through the speaker 50 inserted into the ear hole of the subject, and the speaker 50 is preferably formed in an earphone type.

The therapeutic sound source file maintains the pulse rate of the subject at a normal value using the following principle.

The pitch is determined by the frequency, with high frequencies producing highs and low frequencies producing lows. It is known that high notes have a stimulating effect and low notes have a relaxing effect. This sound source can be used to control tension and relaxation. The therapeutic sound source file can help to restore the pulse rate of the subject to a normal value by using the frequency of the pitch as described above.
