Description

Microwave physical therapy apparatus

[0001] The present invention relates to a microwave physical therapy apparatus, and more particularly, to a microwave physical therapy apparatus that includes a combination of electric therapy using a microwave heating effect and light therapy using an LED light bath, The present invention relates to a microwave physical therapy apparatus for use with an LED light irradiation apparatus capable of improving the wound healing and recovery effect of a lesion.

Generally, electric therapy is used for rehabilitation of dysmenorrhea, enhancement of range of motion, promotion of control of veterinary exercise, restoration and strengthening of muscle atrophy and weakened muscles, relaxation of muscle axis and spasticity, , Improvement of voiding disorder, replacement of prostaglandins, relaxation, edema treatment, fracture healing, tissue and wound healing, and pain relief.

In particular, microwave therapy is a therapeutic method of heating a specific site using the property that microwaves are selectively absorbed in tissues containing a large amount of water. When microwave energy is transferred to human tissues, molecules are frictioned It is known that there are effects such as improvement of blood circulation, reduction of joint stiffness, analgesic action, relaxation of muscular axis, chronic inflammation and promotion of healing of infection, as well as alleviating pain and blood circulation and metabolism by conversion to heat energy.

An example of such a physiotherapeutic apparatus for microwave therapy is a microwave treatment apparatus disclosed in Korean Utility Model Registration No. 20-0049012.

However, such a conventional physical therapy device has a structure in which an oscillation portion (magnetron) for generating a microwave and a radiator for radiating microwave energy are connected to each other by a coaxial cable, so that a short circuit occurs if the electrical contact state of the connection portion is poor As the load is applied, the internal conductor (core wire) located at the center of the coaxial cable generates heat and melts the insulation disposed between the outer conductor and the inner conductor (core wire), so that the inner conductor is concentrated on either side, There is a problem that transmission loss such as loss, radiation loss, and dielectric loss is large.

In addition, since the conventional physiotherapeutic device only emits microwaves through the oscillator and the radiator, there is a limitation in the use of the device, which can only provide a therapeutic effect by microwaves.

On the other hand, phototherapy using the wavelength of a light emitting diode (LED) lamp is a photomodulation by photon absorption to stimulate the cell structure to help the production of collagen and elastin, and the amount of melanin pigment It is known that it has effects such as pain treatment, wound restoration, hair treatment, and inflammation healing, as well as skin trouble improvement and whitening effect, wrinkle improvement, acne, freckles and dark skin tone treatment.

Such an LED light source can effectively treat a large area of diseased area with an appropriate light output, as opposed to intensive treatment of a high power laser at a local area.

In addition, the LED light source emits a light source of a specific wavelength due to a narrow wavelength band width, so that harmful ultraviolet rays (UV) and unnecessary infrared rays (IR) are not emitted, There is an advantage of not damaging.
