〔Example〕

 Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a partially fragmented side view showing an essential part of an infrared therapeutic device for physical examination according to an embodiment of the present invention. The infrared therapeutic device for physical examination of the present embodiment includes a halogen lamp 1, a heat-resistant glass plate 2, a color glass filter 3, a protective pipe 4, an optical fiber light guide 5, a vinyl chloride pipe 6, a probe 7, Condensing lens group 8 and linear polarizing plate 9
And the lens barrel 10 constitute a main part thereof. Reference numeral 11 indicates an output variable power supply circuit for supplying power to the halogen lamp 1, and reference numeral 12 indicates a support member integrally fixing the halogen lamp 1, the heat-resistant glass plate 2, the color glass filter 3 and the protective pipe 4.

The halogen lamp 1 has an inner surface mirror-coated by vapor deposition of metal so that visible light and infrared light diffused from the light source can efficiently enter the base end surface of the optical fiber light guide 5.

The heat-resistant glass plate 2 is crystallized by melting a glass having a special composition containing a crystal nucleating agent such as zirconia and then heat-treating it to precipitate beta-quartz type or beta-spodumene type fine crystals having a small thermal expansion coefficient. It is made of glass. The heat-resistant glass plate 2 serves to protect the color glass filter 3 and the optical fiber light guide 5 by cutting the heat generated by the halogen lamp 1.

The color glass filter 3 is formed of a color glass plate, and the wavelength of the light emitted from the halogen lamp 1 ranges from 0.1 μm ultraviolet rays to 5.0 μm infrared rays. It plays the role of cutting light in the wavelength band.

The protection pipe 4 is a pipe made of aluminum or the like that protects the base end portion of the optical fiber light guide 5.

The optical fiber light guide 5 is formed by bundling 19000 optical fibers each having a core and a clad having a silica-based multi-component structure of 50 μm and having different refractive indexes. The optical fiber light guide 5 is 2.5-
It does not transmit infrared rays in the wavelength band of about 5.0 μm.

The vinyl chloride tube 6 is for inserting the optical fiber light guide 5 and protecting the optical fiber light guide 5 from the surroundings so as not to bend beyond the limit.

The probe 7 is a portion to which the tip of the optical fiber light guide 5 is fixed and which is operated by grasping it with a hand or an arm.

The condenser lens group 8 condenses the light emitted from the front end surface of the optical fiber light guide 5 at a divergence angle of about 30 ° (see FIG. 2), and condenses it into a luminous flux having a circular cross section close to a parallel luminous flux. It is a lens group for doing.

The linear polarizing plate 9 is formed by dyeing a film-shaped polyvinyl alcohol with an iodine solution and sandwiching both front and back sides with optical glass plates, and has a polarization plane of light in a wavelength band of about 0.6 to 2.5 μm. Serves as a straight line. It is known that linearly polarized infrared rays have a remarkable effect on activation of biopolymers, improvement of microcirculation, etc., and enhance the therapeutic effect.

The lens barrel 10 is detachably attached to the tip portion of the probe 7, and when detached, light having a divergence angle of about 30 ° is emitted from the tip surface of the optical fiber light guide 5 and attached. At times, a light beam having a circular cross section that is close to a parallel light beam is emitted.

Next, the operation of the infrared medical treatment apparatus for physical therapy according to the present embodiment configured as described above will be described.

Light including infrared rays generated from the halogen lamp 1 is cut by the heat-resistant glass plate 2 to be heat-resistant glass plate 2.
Through.

Next, the light that has passed through the heat-resistant glass plate 2 is cut by the color glass filter 3 into light in the wavelength band of about 0.1 to 0.6 μm, and enters the proximal end surface of the optical fiber light guide 5.

The optical fiber light guide 5 further cuts light in the wavelength band of about 2.5 to 5.0 μm, passes light in other wavelength bands, and the passed light is reflected by the clad inside the core of each optical fiber. While reaching, the light reaches the tip surface and is emitted from the tip surface of the optical fiber light guide 5.

The light emitted from the front end surface of the optical fiber light guide 5 is condensed by the condenser lens group 8, further linearly polarized by the linear polarizing plate 9, and irradiated onto the affected area.

At this time, since the optical fiber light guide 5 is flexible and can be bent, by operating the probe 7, the affected part of any part can be operated as shown in FIG. 3 (a).
Infrared rays can be concentrated and irradiated in a spot shape with high energy density as shown in FIG.

As shown in FIG. 3 (b), when the lens barrel 10 is not attached to the probe 7, the light emitted from the front end surface of the optical fiber light guide 5 has a divergence angle of about 30 °, so infrared rays are not emitted. The affected area can also be irradiated over a wide area.

As shown in FIG. 4 (a), the optical fiber light guide 5
As for the light emitted from the tip surface, 5% of visible light appears red, and 95% of invisible near-infrared rays that enter deep into the body to be absorbed and have a thermal effect.

Further, as shown in FIG. 4 (b), the light emitted from the front end surface of the optical fiber light guide 5 has a peak intensity in the vicinity of 1.0 μm and has a wavelength band of about 0.6 to 1.0 μm. Light has a great ability to penetrate the living body and promotes heating and activation of the deep part of the living body. In addition, infrared rays in the wavelength band of about 1.0 to 2.5 μm have a property of being well absorbed by water occupying most of the living body, and raise the temperature of living tissue to activate the tissue.

By the way, since the infrared medical treatment apparatus for physical examination of this embodiment uses the halogen lamp 1, the output variable power supply circuit 1
1, the output can be easily changed, and the output can be continuously changed from 0.0 to 3.0 W, for example. It should be noted that when the probe 7 or the lens barrel 10 is brought into contact with the affected area to irradiate infrared rays, low-power irradiation is performed, and when irradiation is performed away from the affected area, high-power irradiation is performed.

[Effect of device]

As described above, according to the present invention, the light including infrared rays generated from the halogen lamp is guided to the affected area by using the flexible optical fiber light guide, so that even a small affected area can be treated. There is an effect that infrared rays having a sufficient energy density can be emitted.

Further, since the optical fiber light guide has flexibility, there is an effect that it is easy to handle and is easy to use, and infrared rays can be radiated to any affected part of any part.

Therefore, since the infrared therapeutic device for physical examination of the present invention can irradiate the affected area with infrared rays in high energy density in a spot shape, it is effective for the following indications.
