EXAMPLE A first example of the present invention will be described below. FIG.
FIG. 2 is a block diagram of the first embodiment of the present invention, and FIG. 2 is an external view of the same device. In FIG. 1, 1 is a potential treatment bed and 2 is a vibration detecting means. The vibration detecting means 2 also serves as the human body detecting means 4, the biological information detecting means 5, and the body movement detecting means 6. Here, the piezoelectric element is formed into a tape shape or a coaxial cable shape. Here, this is arranged in a meandering manner on the back surface of the front cloth of the mattress 3 which serves as a human body supporting portion of the electric potential treatment bed. The human body detection means 4 includes a vibration detection means 2 and the vibration analysis means 7 includes a first filter 8 as a first extraction means, a filter 9 as a second extraction means, and a calculation means 10. 11 is a site identification means,
Reference numeral 12 is a control means. The biological information detecting means 5 is provided with the vibration detecting means 2 and the periodicity analyzing means 13, and 14 is a physiological state determining means. The body movement detecting means 6 is the vibration detecting means 2
And integrating means 15. Reference numeral 16 is a control unit having a signal processing unit and a control unit built therein.

The operation of the above configuration will be described below. Here, the piezoelectric element used as the vibration detecting means 2 is formed into a tape shape or a coaxial shape by forming a polymer piezoelectric material such as polyvinylidene fluoride (PVDF) into a thin film and attaching a flexible electrode film on both surfaces. It is a thing. It is sewn into a piece of cloth and is arranged under the top cover of the layered structure of the mattress 3. The user does not recognize that the vibration detection means 2 is provided, not only by appearance but also by touch.

Next, the signal detected by the vibration detecting means 2 will be described. When a person lays on the electric potential treatment bed 1, body movements and turning over when entering the bed, vibrations caused by small body movements such as heartbeats and breathing cause deformation of the piezoelectric element, and a voltage is generated by the piezoelectric effect. And output a signal. The vibration signal detected here is first sent to the vibration analysis means 7 of the human body detection means 4, and is separated into a heartbeat signal component and a respiratory signal component by the first filter 8 and the second filter 9. The separated components are calculated by the calculating means 10
Then, the power value of each component is calculated by FFT, and the power ratio of “heartbeat component Phr / breathing component Presp” is calculated. The power value of the calculation result is sent to the part specifying means 11. The part specifying means 11 has the following judgment expressions 11- (1), (2), and (3) for specifying a part, and from this judgment expression, which part of the human body the human body detecting means 4 has detected. Specify whether to hit. That is, the principle is that the output ratios of the heartbeat signal component and the respiratory signal component are different for each human body part.

Description will be made with reference to FIG. 3A is a heartbeat component, and FIG. 3B is a power value calculated by the calculating means after extracting the respiratory component. The vertical axis shows the power value and the horizontal axis shows the frequency. (1) chest, (2) waist,
(3) is based on the vibration signal detected from the foot. For example, since a vibration signal greatly affected by the movement of the lungs and diaphragm due to respiratory activity can be detected from the chest of the human body, a large power value as shown in (1)-(b) of FIG. 3 can be obtained. In some cases, only a small power value can be obtained as in (3)-(b). Since the heartbeat component is a vibration generated by the movement of blood circulation system and can be detected systemically, a certain power value can be obtained from the whole body as shown in FIG. From this, the site determination is performed using the following determination formula.

Judgment Expression 11- (1) Phr / Presp <0.5 → Chest 11- (2) 0.5 <Phr / Presp <1.5 → Waist 11- (3) 1.5 <Phr / Presp → When the foot part identification unit 11 identifies the site, the control unit 12 records an appropriate treatment method for each site and outputs a control signal SIG related to the treatment method to the treatment device.

It is also possible to use a judgment formula that pays attention to the fact that the absolute value of the power value of each component detected for each part is different. The calculation means 10 calculates “the power value of the frequency of the respiratory component + the power value of the frequency of the heartbeat component”, and the following state determination is performed. For example, if the calculation result is smaller than the preset value, there is no biological signal in the human body contact part where the vibration detection means is arranged, and “the human body is not actually in contact with the human body contact part of the treatment device”. Can also be determined. Therefore, at this time, the control means 12 can perform control to stop the operation of the treatment device.

On the other hand, in the biometric information means 5, the vibration signal detected by the vibration detection means 2 is used as the periodicity analysis means 13
The periodicity analysis is performed by. The periodicity analysis result is sent to the physiological state determination means 14, and the peak frequency is detected in the range of 0.5 to 2 Hz and calculated as the heart rate to determine whether the heartbeat is stable, whether it is too early or too late. To do. If no clear periodicity is observed within a certain period of time, analyze as an arrhythmia. The physiological state determination unit 14 outputs the progress of the determination result from the start of the treatment, and the control unit 12 controls the continuation and the stop of the treatment based on the progress.

On the other hand, in the body movement detecting means 6,
The signal detected by the vibration detection means 2 is integrated by the integration means 15, compared with a preset threshold value, and when an integrated value equal to or greater than the threshold value is calculated, the signal is output to the control means 12 as body motion. It is assumed that the sleeping person has a body movement such as turning over during treatment. As shown in FIG. 3, the voltage detected by the vibration detection means 2 and output is as shown in the upper diagram of FIG. 3, and the integrated value output by the integration means 15 at that time is small at rest, During body movement, it increases according to the size of body movement.
When a large body movement that causes a posture change occurs, an integrated value equal to or larger than the threshold value is calculated. The determination result is sent to the control means 12, and if the determination result is a body movement, the control means 12 resets the control settings so far, and refers to the identification result of the site identification means 11 again to control the treatment device. For example, the body part determination was performed on the waist until then due to the occurrence of body movement, and the treatment control suitable for the lumbar treatment was performed from the control means 12, but the body movement determination means 6 determines that the body movement has occurred, and controls the treatment device. Suppose the settings are reset. The part specifying unit 11 specifies the part and outputs the result as the foot. The control means 12 controls to change the treatment method according to the foot, and in this treatment device, controls the treatment device so that the treatment is stopped if the foot is not treated.

With the above operation, the following effects can be obtained. Since the treatment method is controlled by specifying the part of the human body on the treatment device, the optimum treatment method can be used for each part. At the same time, the change in physiological condition can be fed back, so that the treatment device can be controlled according to the effect of treatment.

Further, since it is known that the body movement has occurred, the posture change can be detected and the treatment can be performed after the posture change, so that the person under treatment is not restricted in posture and can freely move. You can get treatment and the accuracy of treatment improves.

Further, by using the vibration detecting means 2 as the human body detecting means 4, it can be attached to the human body supporting portion of the therapeutic device, and the appearance is the same as the conventional one, without giving the user a feeling of discomfort. It can be configured as used.

Since the vibration analysis means 7 is constructed so as to extract the heartbeat component and the respiratory component, the human body part specifying means 1
1 can identify and specify the chest, waist, and feet of the human body.

Further, the biological information detecting means 5 is also used as the vibration analyzing means 2 and the periodicity analyzing means 13 is provided, so that the human body detecting means 4 and the signal detecting section are shared, and the apparatus has a simple structure and low cost. Can be realized. Regarding the biological information with or without periodicity, it is possible to know the change in physiological state, which is the heart rate in this embodiment.

Further, the body motion detecting means 6 also serves as the vibration analyzing means 2 and the integrating means 15 is provided, so that the human body detecting means 4 and the signal detecting section are shared, and the apparatus is realized with a simple structure at a low cost. can do.
