Description

[Detailed Description of the Invention] The present invention relates to a device for treating cancer inside a living body by applying a high-frequency electromagnetic field.

There is a method of treating cancer that takes advantage of the fact that cancer is more sensitive to heat than normal tissue, which is called hyperthermia (heat therapy).

This is a treatment that applies heat to cancerous tissue by some method.

Methods for applying this heat include methods that use hot air, hot water, etc., as well as methods that apply high-frequency electromagnetic fields, and many attempts have been made to these methods in recent years.

Various methods have been used to apply a high-frequency electromagnetic field to a living body, such as a method using an electrode plate, a method using an antenna, and a method using a coil.

Regardless of the method used, the high-frequency electromagnetic wave generating section is usually placed in close contact with the patient's body surface in order to efficiently apply an electromagnetic field to the affected area and to reduce unnecessary irradiation to areas other than the affected area.

In such cases, the temperature of the body surface increases due to heat generated by the high-frequency magnetic field from these generating parts, and in addition, the temperature of the body surface in contact with it increases due to self-heating of the high-frequency magnetic field generating parts. As a result, the temperature at the body surface becomes higher than the temperature inside the body, which is the object of treatment, and there is the side effect of causing burns to normal tissues on the body surface.

Purpose 1 of this invention: without causing burns on the surface of the body,
An object of the present invention is to provide a cancer treatment device capable of applying high-frequency electromagnetic waves to the inside of a living body.

The cancer treatment device according to the present invention is a device for treating cancer inside a living body by applying a high-frequency electromagnetic field.
This device is characterized in that an airtight bag is attached and a refrigerant is allowed to pass through the bag.

Hereinafter, the apparatus of the present invention will be explained based on drawings of embodiments.

FIG. 1 is a schematic perspective view of a high-frequency electromagnetic wave generator for the whole body, and FIG. 2 is a schematic perspective view of a high-frequency electromagnetic wave generator (applicator) for local use.

Reference numeral 1 denotes a high-frequency electromagnetic wave generating section, which includes an electrode plate, a coil surface, an antenna surface, etc.

In the whole body treatment shown in FIG. 1, the human body is introduced into the cylindrical generating area 1, and the treatment is performed with the affected area located inside the generating area 1.

In the case of local treatment as shown in FIG. 2, treatment is performed by applying the electromagnetic wave generating section 1 to the surface of the human body in the affected area.

FIG. 3 shows a case in which treatment is performed by sandwiching the human body between electrode plates.

In the device of the present invention, a flexible and airtight bag 2 made of rubber or the like is attached to one side of the high frequency electromagnetic wave generating section.

A refrigerant such as water or air is allowed to flow through the bag body 2 through a passage 3.

In this case, the refrigerant must not reduce the electromagnetic effects.

The bag 2 in FIG. 1 is large enough to come into contact with the human body.

The refrigerant inside the bag body 2 is kept at a slight pressure that is not very high, so that it conforms to the shape of the human body surface and comes into close contact with the human body surface.

4 is a cable for supplying high frequency electromagnetic waves.

Further, 5 is a table that holds the patient's body, and 6 is a support rod that holds the electrode section.

Since the device of the present invention is constructed as described above, the surface of the human body is cooled and burns do not occur.
