Description

  The present invention relates to a medical light-emitting device that promotes healing by preventing infection and suppuration caused by infecting bacteria by being attached to an affected skin area such as postoperative suture marks and flooring.

Conventionally, infectious bacteria easily propagate in affected skin areas such as postoperative suture marks and flooring, and this has been the cause of suppuration. On the other hand, when the affected skin area is dried for the purpose of preventing the propagation of infecting bacteria, the propagation of the infecting bacteria can be suppressed to some extent, but the regenerative power of the skin tissue is reduced and the affected skin area is healed. There was a problem of delay.
For the purpose of coping with such problems, several inventions relating to an apparatus for treating a diseased part of a skin by irradiating a light beam having an effect on sterilization or suppression of propagation of infecting bacteria continuously or intermittently have been disclosed.

The “sterilization patch sheet” according to Patent Document 1 is characterized in that a coating portion is formed by carrying a photocatalytic semiconductor on a harmless sheet material even when pasted on a human body.
This sheet material can be used alone, but a cover sheet may be provided as a covering portion. Further, an ultraviolet radiator may be carried on the sheet material, and an ultraviolet reflection layer made of metal foil or the like may be provided.
According to such a “sterilization patch sheet” according to Patent Document 1, electric power is used by forming a covering portion by supporting a spontaneous ultraviolet radiator or a phosphorescent ultraviolet radiator or both of them. The effect is that the affected skin area can be irradiated with ultraviolet rays.

Patent Document 2 discloses an invention relating to a phototherapy device for use in the vicinity of a patient's skin or in contact with the patient's skin under the name of “flexible irradiation device for phototherapy”. .
In the invention according to Patent Document 2, at least one light emitting diode is disposed on a flexible substrate, and a covering material is provided so as to be in contact with the skin. A therapeutic effect can be expected.

Patent Document 3 discloses an invention relating to a phototherapy device under the name “phototherapy device”.

For example, a prism sheet is provided on the lower surface of the sheet body 2 to provide a light condensing effect from the semiconductor light emitting element to the front inside the sheet body 2, and a diffusion sheet is provided between the prism sheet and the sheet body 2. , Diffusion cut of light to the lower surface side of the sheet body 2 is promoted by providing a layer that changes the refraction of light, such as forming a thin notch in the sheet body 2 or molding with a different resin material layer May be.
Even when the light diffusing body 3 is not used, in order to more effectively prevent the near-ultraviolet light 21 emitted from the near-ultraviolet light emitting portion 4a from being attenuated, the entire upper surface 2a of the sheet body 2 is covered. Thus, it goes without saying that a light reflecting material or an ultraviolet shielding material may be installed.
As described above, the case where the diffuser 3 is not dispersed inside the sheet body 2 is the same in the second to fourth embodiments to be described.

Further, as shown in FIG. 1B, for example, the near-ultraviolet light emitting section 4a according to the first embodiment is configured by the substrate 9 and the semiconductor light emitting element 10 mounted on the surface thereof, and the semiconductor light emitting element is, for example, 405 nm. May have a peak wavelength. The bare chip 11 may be directly mounted on the substrate 9 in the near ultraviolet light emitting unit 4a.
