Abstract

An optical treatment device having a light emission element, a power source for supplying a power to the light emission element and an attaching member for attaching the light emission element to an arbitrary portion such that a light emission face of the light emission element faces a desired portion to be irradiated, whereby the light emission element can be detachably attached to the arbitrary portion and a light such as infrared rays, a laser light and so on can irradiate or heat a very small area of the desired portion.

Claims

1. An optical treatment device comprising:

a generally opaque housing of lightweight and portability capable of being supported on a limb or body portion of the user, said housing having a light transmissive passage extending outwardly therefrom,

a light emission element located in said housing having a face aligned with said passage and through which light radiation is emitted,

a source of current for supplying power to said light emission element and means for attaching said housing directly to the body of the user adjacent the area of the body selected for treatment such that the radiation emitted from face of said light emission element passes through said passage directly onto the skin of the user solely within the selected area of the body.

2. An optical treatment device according to claim 1, in which said means for attaching said housing is provided on the rear surface of said housing opposing the opening therein, and includes bonding means by which said light emission face of said light emission element closely contacts the selected area of the body.

3. An optical treatment device according to claim 2, in which said bonding means is an adhesive tape.

4. An optical treatment device according to claim 2, in which said bonding means is a suction pad.

5. An optical treatment device according to claim 1 in which said light emission element comprises a substrate, a semiconductor light emission element formed on said substrate.

6. An optical treatment device according to claim 5, further comprising a connector for electrically or mechanically coupling or detaching said light emission element and said power source.

7. An optical treatment device according to 1 in which said light emission element emits infrared rays.

8. An optical treatment device comprising:

a housing having a base formed with a light transmissive passage therein and a cap aligned with said passage and closing the same at one end, said housing being light in weight and portable,

a light emitting element for generating an irradiating light and having a face through which said irradiating light is emitted, said light emitting element being mounted in said cap so that said face is aligned with the passage in said base to permit the light to exit therefrom,

a source of current for supplying power to said light emission element and means for attaching said housing directly to the body of the user adjacent the area of the body selected for treatment such that the radiation emitted from face of said light emission element passes through said passage directly onto the skin of the user solely within the selected area of the body.

9. An optical treatment device according to claim 8, wherein the support base is fixedly engaged with said cap and said attaching means is fixed to its free surface of said support base.

10. An optical treatment device according to claim 9, in which said cap member and said support base are made of resinous material.

11. An optical treatment device according to claim 9, in which said light transmission passage of said support base is an opening.

12. An optical treatment device according to claim 11, in which said support base is provided on a surface of said opening with reflecting means.

13. An optical treatment device according to claim 9, in which said light transmission passage of said support base includes a concave lens.

14. An optical treatment device according to claim 9, in which said light transmission passage of said support base includes a convex lens.

15. An optical treatment device according to claim 9, in which said support base is made of the resinous material which is colored when it receives a light from said light emission element

16. An optical treatment device according to claim 8, in which said cap member is made of a resinous material which is colored when it receives the light from said light emission element.

17. An optical treatment device according to claim 9, in which said cap member houses a dry cell as said power source for supplying a power to said light emission element and said dry cell supplies a power automatically to said light emission element when said cap member is engaged with said support base.
