Abstract

PURPOSE: To obtain a penetrating effect of a non-contact massage suitable for wounded tissues by arranging the distance between the transmitting ends of two low frequency generators so that resonance is generated when identical signals are inputted to them simultaneously, and transferring vibration to a portion of body to perform massage. CONSTITUTION: The low frequency generator 1 is a 0-120 Hz distorted super low frequency horn. The transmitting ends of two low frequency generators 1 are disposed oppositely. The space between them is used for accommodating the receiving portion of the body. Identical signals are inputted simultaneously, but the phase of the signal and the distance between the transmitting ends are so controlled that the polarities of the two low frequency generators are contrary to one another. Resonance waves are generated between the two low frequency generators. The arrow heads show the transmitting state of this low frequency wave. Thus the portion of the body in this space is compressed by waves with air as the media, massage therapy effect is obtained through the vibration effect of muscles.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a kind of physical therapy device,
In particular, it relates to a kind of low frequency resonance physical therapy machine.

[0002]

BACKGROUND OF THE INVENTION Traditional artificial massage effects are entirely determined by the experience and professional knowledge of the practitioner. In particular, the treatment of trauma requires a professional masseuse. However, artificial massage requires the help and place of a full-time person, is very inconvenient, and cannot be massaged depending on the location of injury. On the other hand, the massage device has an opportunity structure to perform massage by reciprocating thrust and rotation, or vibration of an ultrasonic transducer, so that the user can feel free to massage at home without spending manpower or long time. There are advantages. However, it has a drawback that unevenness of contact surface and excessive force are concentrated, and the above-mentioned contact-type massage methods of both types have a drawback that the damaged tissue cannot be massaged and cannot penetrate deeply inside. Therefore, the effect was not ideal.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a physiotherapy machine which is a non-contact type and can be applied to injured tissue and can deepen the massage effect into the body.

[0004]

The present invention takes advantage of the fact that when a low-frequency sound pressure is applied to a human body, vibrational compression mediated by air can penetrate deeply into the human body without directly contacting the surface of the human body. However, since the low frequency has a diffusive property, energy is not concentrated, so it is necessary to shorten the distance and concentrate the energy of the wave, but the above-mentioned distance is such that it can enter the body part to be massaged. There must be. Therefore, in the present invention, two opposite low frequency generators are used, and the same signal is input at the same time, but the polarities of the two low frequency generators are opposite to each other, and the signals are between the two low frequency generators. The body part placed between them is vibrated by the wave motion generated by, and the therapeutic effect is obtained through the muscle vibration effect. In addition, a hollow conduit is used to communicate between two independent low-frequency generators, a low-frequency positive wave is emitted from one end, enters the conduit through the other end, and back waves are generated in the opposite direction. By generating and circulating this, the massage treatment effect is enhanced with a wave on the body placed between them.

[0005]

The present invention provides a kind of low frequency resonance physical therapy machine. It is a kind of non-contact physiotherapy device, which is used for massage treatment of injured tissue, in which two opposite polarity low frequency generators with opposite polarities are attached with their firing ends facing each other, and the body receiving massage between them. A space is provided for placing the part of. Then, the low-frequency generator simultaneously emits waves in a state of opposite polarities to generate resonance, thereby achieving a massage treatment effect on the body part placed therebetween. Further, a hollow conduit may be used to communicate between the two independent low frequency generators, and the low frequency generator may be installed at one or both of the two opposite ends. In this case, a low frequency positive wave is emitted from one side,
It penetrates into the conduit through the other end and generates a back wave in the opposite direction, which is launched from the back of the generator and launched through the other end of the conduit, thus circulating to the body in between. The effect of wave massage treatment is enhanced.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Shown in FIGS. 1-3 are three embodiments of the present invention. In the first embodiment of FIG. 1, the firing ends of the two low-frequency generators 1 and 2 are aligned, and the space between them is used as a body containing portion. At the same time, the same signal is input, but the phases of the two low frequency generators and the firing end distance are controlled so that the polarities of the two low frequency generators are opposite to each other, and a resonance wave is generated between the two low frequency generators. The arrow in FIG. 1 indicates the propagation state of this type of signal, whereby the body part placed between them is vibrated by the air-borne wave compression to achieve the therapeutic effect via the muscle vibration effect. .

2 and 3 show Embodiments 2 and 3 of the present invention. The difference between these two embodiments and the first embodiment is that the two independent low-frequency generators 1 are communicated with each other by the hollow conduit 2 and one of the two facing ends (see FIG. 2). (As shown), or two low frequency generators (as shown in FIG. 3) are attached, and a low frequency positive wave is emitted from the end face of one low frequency generator 1 so that an intermediate body and air medium can be transmitted. The effect of providing a low frequency in this way by letting it enter into the hollow conduit 2 from another one is that the low frequency is unlikely to be absorbed and reflected in the low frequency, and is not easily attenuated during the transmission. The combination of designs is conducted through the conduit to the rear portion of the low frequency generator 1, where the low frequency also produces one back wave in the opposite direction, as indicated by the phantom arrow, the low frequency generator 1 After being launched from the back of the Emitted from another end of the tube 2, it is to perform the massage therapy with the wave in the body placed therebetween by circulating in this way.

Accordingly, the above-mentioned low frequency generator of the present invention is an ultra low frequency horn having an extremely low distortion of 0 to 120 Hz, and the low frequency generator is fixed to the face plate position of the end of the hollow conduit with a screw and an adhesive. Alternatively, it should be fixed to the face plate position of one box, and the distance between the two low frequency generators should be set in the form of a single bed (shown in Fig. 4) so that it can move on a fixed orbit and Treatment is advanced to the affected area. The figure shows a situation in which sound wave resonance gives vibration to the body, but naturally, it may be separately provided like a speaker cabinet of an audio device and optionally portable so that treatment can proceed at any point. . Further, in order to perform vibration therapy on different parts of the body at different frequencies and at appropriate distances, the present invention utilizes the effect of positive-negative polarity reciprocity to simultaneously generate positive and negative waves in a low frequency generator. However, with a phase difference of 180 degrees, a positive wave is sent forward, and a negative wave (ie, back wave) is introduced into the hollow conduit from the back of the horn of the low frequency generator,
The rear part of the horn is completely impermeable to the hollow conduit and is made impermeable, so that it flows in the hollow conduit and is discharged from the hollow conduit opening shown in Example 2. Then, in the third embodiment, the positive and negative waves simultaneously reach through the hollow conduit and have the same amplitude, so that the positive and negative waves have a doubled wave width to obtain an enhancing effect. That is, the therapeutic effect is enhanced and the treatment becomes easier.

[0009]
