Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an affected part in the body such as the mouth, the nose, the ear, the bronchus, the inside of the stomach or the like, or an affected part of the body surface such as the shoulder, back or foot. The present invention relates to a radiation treatment tool that emits light to treat an affected area or prevent illness.

[0002]

2. Description of the Related Art Radiation therapy is a technique of irradiating an affected area of a patient with light such as infrared rays, ultraviolet rays, or visible light by a radiation therapy apparatus, and treating the affected area with light energy to prevent the disease.

[0003]

Since the radiation treatment apparatus artificially produces light (infrared rays, ultraviolet rays, visible rays, etc.) used for treatment using a lamp, a laser, or the like,
Although the cost of the device itself is relatively low, the patient had to lie down in bed or sit still in a chair while receiving radiation therapy. That is,
His range of activity was limited during treatment. In addition, since the patient has to stay still for a long time, it is difficult to treat for a long time. It is also difficult for patients who do not need hospitalization to visit the hospital every day. Further, in the conventional radiotherapy, a treatment space and a treatment time are required in addition to the fee for using the radiotherapy apparatus, so that the treatment cost becomes high.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a radiotherapy device capable of performing long-term radiotherapy without restricting the behavior of a patient undergoing radiotherapy, and at a low treatment cost.

[0005]

A radiotherapy device of the present invention uses an optical fiber, one end of which is arranged at a position for receiving the light of the environment of a medical treatment person, and the other end of which is directed to the medical treatment part. The technical means of being adopted is adopted. As an embodiment of the present invention, the radiation treatment tool may be provided with a light condensing section that collects light in the light receiving section. Further, an optical filter may be used in the radiotherapy tool so that only the light of a specific wavelength is applied to the affected area. As a specific example of this, an optical filter is attached to the light receiving portion or the radiation portion, or a coating material that acts as a filter is applied. Alternatively, the optical fiber itself has a function of a filter. An example of this is means such as using a colored optical fiber. Further, as an embodiment of the present invention, the radiation part may be inserted into the body to treat the affected part in the body or prevent disease, or the radiation emitted from the radiation part may be directed to the surface of the body. The surface affected area may be treated or disease may be prevented.

[0006]

According to the operation of the present invention, first, the radiation part of the radiotherapy tool is guided to the affected part so that the light emitted from the radiation part reaches the affected part. The light of the environment of the user (natural light existing around the user, light such as illumination) is made to strike the light receiving unit. As a result, the light of the environment of the user is radiated from the light receiving portion through the optical fiber to the affected portion from the radiation portion.

[0007]

EFFECTS OF THE INVENTION The radiotherapy device of the present invention can be left on the user and can be freely acted even during use because it is applied to the affected area by utilizing the light of the environment of the user. In this way, the user can act while using the radiation treatment tool, and thus, it becomes possible to perform treatment for a long time, and a high therapeutic effect or preventive effect can be expected. In addition, since the light of the environment of the user generally has light of various wavelengths, infrared rays, ultraviolet rays, visible light, etc. are applied to the affected area,
The therapeutic and preventive effects are very high. (And, if there is an inappropriate wavelength depending on the affected part, a filter can be used to cut off the inappropriate wavelength. The parenthesized is an embodiment.) Furthermore, the basic part of the radiotherapy device of the present invention is Since it is possible to use an optical fiber, the cost of the radiotherapy device can be significantly reduced as compared with the conventional one. Therefore, the radiotherapy tool can be provided to the user at a low cost, and since a conventional treatment space or the like is not required, the cost for the radiotherapy can be significantly reduced compared to the conventional cost.
