Description

Microwave Thermotherapy Apparatus

The present invention relates to a microwave thermal therapy device, and more specifically, to a built-in two or more microwave generators that radiate microwaves of different wavelengths in one treatment device to superimpose a single frequency or two or more microwaves depending on the affected state. The present invention relates to a microwave heat therapy device that radiates and treats multiple lesions.

As shown in FIG. 1, when the body temperature rises above the reference value (36.5 ° C.), the blood circulation and immunity gradually increase in proportion to the maximum value at about 42 ° C .. On the other hand, various bacteria are active until the baseline, but gradually slowed down from the baseline. Influenza bacteria die at 39.5 ℃, cancer cells at 42 ℃, and tuberculosis bacteria at the skin cancer and lymphatic system at 44 ℃. Therefore, by using this principle, a device for radiating high-frequency electromagnetic waves such as far infrared rays or microwaves to penetrate deeply into the human body has been developed.

Republic of Korea Patent No. 673756 is a microwave electromagnetic wave generator (2) by the microwave generator 16, in particular for the human body and animals for medical treatment, heat energy is generated by the electric field energy of the microwave electromagnetic waves, such as cancer cells Methods and devices for killing noncellular tissues are provided.

However, the patent not only can cure cancer, but also the device can emit only one frequency of electromagnetic waves, there is a problem that must be used to arrange a plurality of expensive microwave electromagnetic generators as needed.

In addition, as a far-infrared ray treatment device, the Republic of Korea Patent No. 314896 can only treat visceral disease, the Republic of Korea Patent No. 188329 only shoulder swelling, and the Korean Utility Model Registration No. 408351 can treat only visceral disease. There is a problem that must use a treatment device. In addition, a microwave thermal therapy apparatus having a generator for generating a microwave, a power supply unit, and a control unit, wherein the control unit includes an irradiation time operation timer, an intermittent operation timer, a second connection terminal, and a remote switch, according to Japanese Patent Application No. 2004-243935. It is open.

The above technology can be used simultaneously by connecting two microwave thermotherapy treatment devices using both connecting terminals, with the trunk interposed between both sides of the affected area. The superimposed microwaves can raise the temperature of the tumor site to 43 ° C in a short time. The advantage is that it does not require a long time for treatment. However, the depth of the affected area must be different for each symptom of the affected area, and the depth of heat penetration must vary according to the depth of the affected area. The above technique sets the operating time of the irradiation time operation timer and the intermittent operation timer to determine the depth of heat penetration according to each affected area. The operation is very difficult because it can be adjusted. In addition, since the microwave therapy device is a very expensive device, it needs to be connected to two microwave therapy devices in order to sufficiently heat, thereby increasing the cost.

Therefore, there is a demand for the development of a microwave thermal therapy apparatus that can treat a microwave having a single frequency or a plurality of microwaves having different frequencies by overlapping radiation with one microwave thermal therapy device, according to the location of the affected part.

The present invention was developed in order to solve the above problems, one microwave heat treatment device for receiving a microwave generator having a different wavelength output inside the device, the output radiated from the plurality of microwave generators according to the position of the affected part Can be treated alone or superimposed into the affected area of the patient to treat multiple affected areas.

A circuit as shown in FIG. 4 is embedded inside the main body 100 to emit microwaves having various outputs by driving the microwave generator. The power supply unit 220 receives an AC power source AC from the outside and receives the microwave generator M1. And converts to a DC power source having an output for driving, M2, M3.

At this time, an emergency switch (ES) is provided between the AC power source (AC) and the power supply unit 220, so that the patient feels intolerable heat or presses it in another emergency situation so that the power is cut off.

The DC power output from the power supply unit 220 is input to the first, second, and third transformers T1, T2, and T3, respectively. At this time, the power input to each of the transformers T1, T2, and T3 is branched. They are supplied in multiple stages at different primary winding ratios.

As an example, the power is selectively supplied to the winding position having the maximum output in the primary winding of the first transformer T1 via the switch A1, and then the power is supplied to the winding position having the intermediate output of the maximum output. To be selectively supplied via switch A2.

Of course, the number of transformers and their outputs can be configured to vary. In the present invention, for the convenience of description, examples are given to have the configuration as described above.

The thermo switch TS1, TS2, TS3 is provided between the power supply unit 220 and each of the transformers T1, T2, T2 so that the thermo switch is opened when the microwave generators M1, M2, M3 are overheated. It is configured to have overheat protection.

Meanwhile, microwave generators M1 and M2 are controlled by controlling the opening and closing of switches A1, A2, A3, B1, B2, B3, C1, C2 and C3 provided in the primary windings of the transformers T1, T2 and T3. The controller 240 controls M3 to have various outputs. In the present invention, a case in which microwaves are emitted in six modes will be described as an example.

First, the controller 240 is configured to selectively open and close the switches A1, A2, A3, B1, B2, B3, C1, C2, C3 according to each mode, and the user inputs the mode setting key 230. The controller 240 performs a command according to the corresponding mode.

In order to prevent the microwave generator from occurring due to the inflow of microwaves generated from neighboring microwave generators while allowing microwaves generated from the plurality of microwave generators M1, M2, and M3 to overlap each other according to each mode. The waveguides 310, 410, 510, the radiation shades 320, 420, 520, and the reflection shades 330, 430, 530 may further have a structure.

The waveguides 310, 410, and 510 induce the microwaves generated from the microwave generators M1, M2, and M3 in a predetermined direction, and as shown in FIG. 5, the waveguides 310, 410, and 510 of the sphere 600 having the microwave outlet 610 at the bottom thereof. It is mounted so as to face each other at an angle to the upper end is configured to overlap each other when the microphone wave is discharged into the inside of the sphere 600, and the radiation shades (320, 420, 520) are mounted at the end of the waveguides (310, 410, 510).

The radiation shades 320, 420 and 520 are intended to diffuse the microwaves derived from the conduit tubes 310, 410 and 510 into the sphere 600 so that the overlapping can be easily performed. In the inner space portion, the reflection shades 330, 430, 530 are fixed to the support bars 331, 431, 531.

By directing the tip of the reflector shades 330, 430, 530 toward the waveguides 310, 410, 510, the microwaves emitted from the waveguides 310, 410, 510 are easily radiated, and also minimize the backflow of microwaves from the interior of the sphere 600.

In addition, wrinkles 321, 421, 521 are formed around the inner side of the radiation shades 320, 420, 520 from the upper side to the lower side so that the incoming microwaves are diffusely reflected to further minimize the backflow of the microwaves.

The output form of the microwave according to the mode execution of the controller 240 will be described.

6 shows the depth at which heat penetrates the human body depending on the wavelength of the microwave.

As shown here, the microwave generated solely from the microwave generator M1 having an output of 2,450 MHz raises the body temperature to about 45 ° C. at a depth of 13 mm of the human body, and is generated solely from the microwave generator M2 having an output of 900 MHz. The microwaves raise the body temperature to about 45 ℃ at 28mm depth of the human body, the microwave generated alone from the microwave generator M3 having an output of 400MHz will raise the body temperature to about 45 ℃ at 60mm depth of the human body.

By properly superimposing microwaves with this function, the body temperature is increased at various depths of the human body.

Hereinafter, the reason and operation for each mode will be described through embodiments.

This is applied to the case where the depth of the affected area is shallow, such as finger rheumatism around 10mm, to perform the treatment.

Mode 2-The controller 240 turns on the switches A2 and B2, and turns off the remaining switches A1, A3, B1, B3, C1, C2, and C3 so that the first microwave generator M1 having a frequency of 2,450 MHz. 350W, which is the median of), and 400W, which is the median of the second microwave generator M2 having the frequency of 900MHz, are output so that the total 750W is outputted. Raise.

This is used when the affected part is slightly deeper than Mode 1 and the plurality or the size of the affected part is relatively large.

Mode 3-The controller 240 turns on the switch B1 and turns off the remaining switches A1, A2, A3, B2, B3, C1, C2, and C3 to generate a second microwave generator M2 having a frequency of 900 MHz. The maximum value of 800W is to be output as shown in Figure 9 to increase the body temperature over 45 ℃ at a depth of about 28mm.

This is used when the affected part is slightly deeper than Mode2 but the affected part is one.

Mode 4-The controller 240 turns on the switches B2 and C2 and turns off the remaining switches A1, A2, A3, B1, B3, C1 and C3 so that the second microwave generator M2 has a frequency of 900 MHz. 400W, which is the median of, and 500W, which is the median of the third microwave generator M3 having the frequency of 400MHz, are output so that a total of 900W is outputted, thereby increasing the body temperature by 45 ° C. or more at a depth of about 28mm to 60mm as shown in FIG. 10.

This is used when the affected part is slightly deeper than Mode 3 and the plural or the affected part is relatively large in size.

Mode 5-The controller 240 turns on the switch C1, and turns off the remaining switches A1, A2, A3, B1, B2, B3, C2, and C3 to generate a third microwave generator M3 having a frequency of 400 MHz. 900W, which is the maximum value of), is output to increase the body temperature by 45 ° C. or more at a depth of 65 mm or more as shown in FIG. 11.

It is selected when the affected area is deep, such as femoral disease or prostate disease.

Mode 6-The controller 240 turns on the switches A3, B3 and C3 and turns off the remaining switches A1, A2, B1, B2, C1 and C2 so that the first microwave generator M1 having a frequency of 2,450 MHz. Outputs 250W, the lowest value of the second microwave generator M2 having a frequency of 900MHz, 300W, and 400W, the lowest value of the third microwave generator M3 having the frequency of 400MHz, so that a total of 950W is outputted. As a result, as shown in FIG. 12, the body temperature is increased to about 45 ° C. at a depth of about 10 mm to 70 mm.

Choose for deep, inclusive cases such as abdominal disease, influenza flu, and heart disease.

In this way, the output is designed differently according to the depth of heat penetration, so the deeper the depth of heat penetration, the warmer the volume, so the output is designed higher.

Therefore, by operating the mode setting key 230, the microwave generator can be adjusted alone or in combination of two or more according to the depth of the affected area, thereby effectively treating the affected area.

In addition, the affected part may be local, but when the affected part is widely distributed in the body, there are many parts to be heated by radiating microwaves with a micro thermal therapy device. Accordingly, it is necessary to change the position of the microwave spinneret according to the portion to be heated.

At this time, the change of the position to be heated is to change the rotating chair in which the patient is sitting when changing horizontally. In this way, simply turn the swivel chair can be rotated 360 ° so that you can treat anywhere you want.

On the other hand, when you want to change the position of the microwave radiation vertically, by pressing the elevating button 121 installed on the front of the main body 100 to move the device up and down.

By changing or moving the horizontal and vertical heating position of this method, it is easy to enlarge the heating part and to repeatedly warm the affected part.
