DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first embodiment of the present invention shown in FIGS.
A microwave generator 1 for generating a microwave, and an antenna unit 2 for radiating the microwave output from the generator 1.
And a support portion 3 that supports the antenna portion 2 and is placed directly on the surface. The above surface includes not only the bed 15 surface but also the floor surface and the chair surface.

The microwave generating section 1 is composed of an inverter type microwave power generating unit (commonly called an inverter type power unit) and generates a microwave of 2,450 MHz. The electrical configuration of the microwave generator 1 includes an oscillator 5 that generates microwaves, a power supply 6 that excites the oscillator 5 to cause it to oscillate, and an output adjuster 4 that adjusts the microwave output.

The intermittent switch 7 is connected to the power source unit 6 and operates the power source unit 6 intermittently.
When is operated intermittently, microwaves are output intermittently. The antenna unit 2 is connected to the microwave generation unit 1, and the antenna unit 2 includes a protruding conductor 8 for guiding the microwave generated by the microwave generation unit 1 and radiating the microwave into the air, and And a reflector 9 for reflecting the microwave radiated to the affected part and directing it toward the affected part.

The microwave generator 1 is mounted at the center of the support portion 3, and reflectors 11 for reflecting microwaves radiated into the air are extended to the left and right of the generator 1. . The reflector 11 has an expandable / contractible mechanism 10 and is made of a bent plate material. Although not shown in the drawings, other constituent members of the reflector 11 may be those capable of reflecting microwaves such as punching metal or metallic corrugated plate material, in which a large number of small bodies are arranged to enable good reflection. Good.
In some cases, legs (not shown) may be provided at the lower ends of the left and right reflectors 11 and 11.

The expansion / contraction mechanism 10 has a space inside, one reflector 11a, the other reflector 11b inserted into the space so that it can move in and out, and the other reflector 11b by pressing the other reflector 11a. It is composed of a fixture 12 which is fixed at an appropriate position with respect to the reflector 11a. On the other hand, a scale 13 for displaying the height of the antenna unit 2 is displayed on the reflector 11a.

The detector 14 is provided so as to face the lower surfaces 3a of the left and right portions of the support portion 3 and detects the grounded state of the lower surface 3a. When the lower surface 3a is entirely in the grounded state. The detector 14 operates and the power supply unit 6 operates.
On the contrary, when the whole or part of the lower surface 3a is not grounded,
That is, when the apparatus of the embodiment is in the inclined state or in the falling state, the detector 14 does not operate, the operation of the power supply unit 6 is stopped, and the generation of microwaves is stopped. In the case of a device having the legs (not shown), the detector 14 is attached to the leg at an appropriate position.

Reference numeral 16 shown in FIG. 1 is a slit plate having slits 17 formed at a plurality of positions, 18 is a lid of the antenna unit 2, and 15 is a lid.
Is a bed for prostrating the patient, 22 is an insulator covering the projecting lead wire 8, 19 shown in FIG. 2 is an indicator for displaying the microwave output value, time, etc., 20 is a timer for starting the treatment and setting the treatment time, Reference numeral 21 is a power switch.

In use, first, the patient is placed on the bed 15
The apparatus of the embodiment is placed at a position to cover the affected area such as the waist or the shoulder. The expansion / contraction mechanism 10 at the lower left and right of the support 3 is moved back and forth to adjust the distance between the affected part and the antenna 2. The microwave generation unit 1 is activated, and microwaves are radiated from the antenna unit 2 to heat the affected area and perform thermal treatment. When the left and right lower surfaces 3a of the support portion 3 are in contact with the surface of the bed 15, the detector 14 operates, and the power supply portion 6 also operates to generate microwaves.

When the intermittent switch 7 is turned on, the power source section 6 operates intermittently such that it operates for 1 second and does not operate for 2 seconds, and the affected area is intermittently irradiated with microwaves. When the intermittent switch 7 is turned on, microwaves are intermittently irradiated to the affected area, and even if the microwave output is increased, burns are less likely to occur. Therefore, when the intermittent switch 7 is turned on, the microwave output is strongly increased. However, heating can be performed with high efficiency, and stimulating treatment can be performed.

In the second embodiment shown in FIG. 4, the supporting portion 3 in the first embodiment is replaced with both end portions of the reflecting portion 9 of the antenna portion 2, and both end portions of the reflecting portion 9 are also used as the supporting portion 3. Then
The member of the support part 3 is deleted.

In the prior art, since the height position of the microwave oscillating tube from the bed is constant, it is not possible to adjust the approach and the separation according to the individual difference of the human body. Therefore, in the case of the above-mentioned separation, the microwave energy reaching the affected area is weak, therefore, the microwave output must be increased, which is uneconomical, and in the case of the aforementioned approach, the microwave reaching the affected area is small. The wave energy was strong and there was a risk of burns.

In the embodiment of the present invention, the microwave generator 1 is supported at a variable height, and the support 3 has a support 3 for covering a diseased part which is a radiation receiving part, and the support 3 is bent to reflect microwaves. Since the expandable and retractable reflector 11 is formed, the microwave generator 1 can be adjusted to approach or separate according to the individual difference of the patient. That is, the person to be treated has the affected part and the microwave generation part 1
Can be adjusted to a suitable interval, and by this adjustment, highly efficient microwave irradiation can be performed on the affected area.

[0020]

According to the present invention as set forth in claim 1, since it has a supporting portion which supports the antenna portion (2) and is directly placed on the floor surface, it is easy to carry and install, and the upper and lower limbs of the human body It can be easily placed locally and microwaved, and the entire device can be made compact.

Since the supporting portion 3 of the present invention according to claim 2 has the reflector 11 for reflecting microwaves,
Most of the microwaves radiated from the microwave generator 1 directly reach the affected area and are used for heating the affected area, and some of the microwaves reaching the reflective area 14 are also reflected by the reflective area 14 to reach the affected area. It is convenient because the affected area can be irradiated with microwaves with high efficiency.

Since the antenna section 2 of the present invention as defined in claim 3 has reflecting portions 9 on its left and right portions which serve as the supporting portion 3 and at the same time reflect the microwave,
It was possible to reduce the number of constituent members of the support portion 3 and reduce the manufacturing cost.
