example 1

[0026]With reference to FIG. 1, there is shown a cross-sectional view of a phototherapy patch according to a preferred example of the present invention.

[0027]As shown in FIG. 1, the phototherapy patch according to the present example includes: an adhesive layer 1, a pharmaceutical drug layer 2, an isolating layer 3, a spontaneous emission layer 4, a passivation layer 5 and a release film 6. In detail, the adhesive layer 1 has a first surface 11 and an opposite second surface 12. Herein, the pharmaceutical drug layer 2 is disposed on the first surface 11 of the adhesive layer 1, while the release film 6 is disposed on the second surface 12 of the adhesive layer 1. Additionally, the isolating layer 3 and the spontaneous emission layer 4 are laminated on the pharmaceutical drug layer 2 in sequence, such that the isolating layer 3 is disposed between the pharmaceutical drug layer 2 and the spontaneous emission layer 4. Finally, the passivation layer 5 covers the pharmaceutical drug laye...

example 2

[0032]With reference to FIG. 2, there is shown a cross-sectional view of a phototherapy patch according to another preferred example of the present invention.

[0033]As shown in FIG. 2, the phototherapy patch according to the present example is the same as that illustrated in the example 1, except that the spontaneous emission layer 7 according to the present example is driven via light illumination and emits therapeutic light. In detail, as shown in FIG. 2, the spontaneous emission layer 7 according to the present example includes an organic emission layer 71 and a solar absorption layer 72. Herein, the organic emission layer 71 is disposed between the solar absorption layer 72 and the isolating layer 3, and the solar absorption layer 72 can convert incident light into electrical energy so as to drive the organic emission layer 71 to emit therapeutic light.

[0034]In the present example, the organic emission layer 71 includes: a first electrode layer 711 disposed on the isolating layer...

Abstract

A phototherapy patch is disclosed, which includes: an adhesive layer, having a first surface and an opposite second surface; a pharmaceutical drug layer, disposed on the first surface of the adhesive layer; and a spontaneous emission layer, disposed over the pharmaceutical drug layer and capable of emitting therapeutic light by light illumination or a chemical reaction. Accordingly, the phototherapy patch according to the present invention has no power supply disposed therein, and thereby is suitable to be manufactured as a particularly thin and thus inconspicuous device.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a phototherapy patch and, more particularly, to a flexible phototherapy patch with no power supply disposed therein.[0003]2. Description of Related Art[0004]With the improvement of the quality of the life, the cosmetology industry has been developed quickly and home medical cosmetology has drawn more attention. Particularly, simpler and personally-operable cosmetological methods have been popular. In addition to conventional drugs and care products, phototherapy has been developed in medical cosmetology industry to more efficiently achieve a cosmetology or treatment object. A medicine journal reported that propionibacterium acnes, which cause redness and inflammation associated with acne, contain porphyrin, and free radicals can be generated by reaction between blue light (its wavelength ranges from about 400 nm to 470 nm) and porphyrin to eradicate propionibacterium acnes so as to reduc...
