Description

Technical Field

[0001] The utility model relates to the technical field of patches, in particular to a phototherapy patch. Background Art

[0002] Photobiomodulation (PBM), as an emerging treatment for chronic wounds, has been shown to reduce inflammation and oxidative stress by regulating a variety of cellular and molecular biological processes, thereby relieving pain and promoting wound healing. Specifically, PBM can affect cell proliferation and migration, control inflammatory responses, promote tissue repair, and accelerate wound healing.

[0003] In the field of wound treatment, different types of light play different roles, and different types of light with similar wavelengths have some similar or identical therapeutic functions. For example, red light and near-infrared light irradiation can promote wound healing, reduce wound exudation, control wound infection, and relieve pain. In addition, combined irradiation with LED red and blue light can more effectively promote the healing of infected wounds and relieve wound pain than simple red light or blue light irradiation.

[0004] In terms of clinical application, photobiological regulation has been shown to have a positive effect on the healing of acute and chronic wounds. For example, for acute wounds, red light-assisted therapy can shorten the wound healing time. For chronic wounds, such as diabetic foot ulcers, atherosclerotic occlusive disease, varicose veins or post-thrombotic syndrome, pressure sores, etc., light therapy can reduce chronic wound secretions, promote epithelialization, increase the number of immune cells, promote the secretion of cytokines and chemokines, accelerate wound closure, and thus promote wound healing.

[0005] However, although light therapy shows good application prospects in wound healing, the combined effect of different wavelengths of light may be stronger and more conducive to the repair of tissue defects in different situations, but there is a lack of relevant device structures that can switch between LED lights of different wavelengths.
