Optical wound therapy apparatus

Abstract

The invention provides an optical wound therapy apparatus comprising light sources, a controller body, a PCB, a top cover, a bottom cover, a radiator and other related structural components. The therapy apparatus is internally equipped with blue (400nm to 490nm), red (600nm to 690nm) and near-infrared (780nm to 970nm) low-power laser lamps or ultra-bright LED light sources, and adopts a mode of comprehensive radiation therapy. The therapy apparatus has the effect of infection clearing, bacteria inhibiting, inflammatory absorption promoting and pain alleviating, and can improve blood circulation, promote granulation tissue maturing, make skin cells grow at the rate of 3-5 times and significantly improve the healing rate of injured tissues. The therapy apparatus has a lighting regulation function, and appropriate lighting parameters can be chosen flexibly to illuminate injured tissue parts according to different biological organisms or different statuses and different symptoms of organisms to affect the biological system. Thus, the work intensity of the nursing staff is lightened greatly, and the workload is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a wound therapy instrument. It is suitable for clinical rehabilitation treatment of skin ulcers of paralyzed patients and diabetic patients and various common burns, scalds, wounds and trauma. Background technique [0002] Biological wound ulcer healing is a very complicated process, including three stages: inflammatory phase, proliferative phase, and repair phase. Each phase overlaps and affects each other. The cells involved include platelets, inflammatory cells, vascular endothelial cells, and fibroblasts. cells, epithelial cells, etc. During the healing period, due to improper treatment and care, the wound strength is reduced, the angiogenesis is reduced, the wound is poorly healed, small ulcers lead to deeper ulcers, and even further complications are caused. There is also the risk of amputation to sever infected underlying tissue and bone. Wounds that do not heal severely impact an in...

Problems solved by technology

[0005] At present, there is still controversy about the application of low-intensity laser irradiation in wound healing. On the one hand, its effect is unstable, which is related to its strong dependence on optical parameters, including different wavelengths, power densities, energy densities, irradiation Frequency (continuous wave or pulse wave), irradiation time, clinical treatment times, treatment intervals, etc. may also be related to the optical properties and functional characteristics of the biological body itself, or both. How to choose the appropriate irradiation parameters for different biological organisms or different states of the organism and different symptoms requires further research on the biological mechanism and law of low-intensity light.

On the other hand, because the current high level of lasers affects the popularization of
