Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a frequency range of 10 to 50.
The present invention relates to an improvement in a conductor used in an ultra-high frequency wave treatment device which irradiates a human body with an ultra-high frequency band electromagnetic wave of MHz and performs thermal treatment by a heat-transfer effect generated in the body.

2. Description of the Related Art FIG. 4 is a block diagram showing the configuration of a conventionally known ultrahigh frequency wave therapeutic device. In the figure, an oscillation circuit 1 has a fundamental frequency of an ultrashort wave as an output, that is, an ISM (Industrial).
Scientific and Medical equipment), frequencies assigned to high-frequency medical equipment, for example, 27.12.
It oscillates at 13.56 MHz and 40.68 MHz. In addition, of the frequencies assigned to the high-frequency-using medical device in the ISM, 2.45 GHz is called a microwave, and has a higher frequency band than the ultrashort wave. The amplification circuit 2 amplifies the signal output from the oscillation circuit 1 to a sufficient voltage.
Amplifies the output signal of the amplifier circuit 2 to a specified power of about 50 W.

The specified power is a value which does not increase to a temperature at which cells of a human body necrotize, for example, 42 degrees Celsius, and is a temperature required for hyperthermia treatment, for example, 38 degrees Celsius, against the cooling effect of the blood flow of the human body. It is recommended that the value be increased to a certain degree. In particular, in patients with sensory nerve paralysis, such as diabetic patients, even if the tissue temperature rises excessively, they do not feel heat, which may cause low-temperature burns or true burns. Become.

The adjusting means 5
The characteristic impedance of the transmission line of the output matching circuit 4 is adjusted using a variable capacitor or the like that varies the capacitance. The lead 6
A capacitor type that constitutes an impedance circuit for the treatment device body by being capacitively coupled in pairs, and exerts a thermal effect on the affected part by high-frequency heating of the human body sandwiched between these conductors ing.

In the device configured as described above, the guide 6 is first fixed to the affected part by a fixing belt (not shown). Then, the affected part, such as an arm or a foot, is sandwiched between two pairs of conductors 6. Since the load impedance applied to the ultra-high-frequency wave treatment device varies depending on the difference in the dielectric constant or the loss of each part of the human body, the impedance of the output matching circuit 4 is adjusted by using the adjusting means 5 so that the impedance of the human body part to be treated is reduced. Align. Then, the ultra-high frequency treatment using the ultra-high frequency treatment device is started.

As another type of the conductor 6, a coil type in which a single conductor forming a spiral coil exerts a heating effect to a deep part of an affected part by the action of Joule heat by eddy current, and the present applicant. 3-2125
Japanese Unexamined Patent Application Publication No. 4 and Japanese Patent Publication No. 6-49080 are known. The conductor disclosed in Japanese Patent Publication No. 6-49080 is basically a coil type, in which a tape-shaped electrode is wound around an arm or a leg, and ultra-high frequency treatment is performed using a spiral electric field method.

Had a structure to do. However, there is a customer's desire to receive ultra-short wave treatment even at home. The problem here is that it is necessary for the patient to easily carry out the work of attaching the lead to the affected part. At home, the role of the surgeon may be performed by the family and caregiver who live together, but when the family or caregiver is absent, the patient must perform the role. In addition, the affected part had to have a structure capable of performing ultra-short-wave treatment not only on the arms and legs but also on the shoulders and hips.

The present invention solves the above-mentioned problems, and
An object of the present invention is to provide a guide for a microwave treatment device that can easily fix a guide to an affected area by a patient himself even when a family member or a caregiver is absent, and can perform a microwave treatment on not only an arm and a foot but also a shoulder and a waist. I do.
