Background technique

Port wine stains, also known as wine-like mites or telangiectasia, are congenital diseases, frequently occurring in the face and neck, mostly unilateral, occasionally bilateral, but also in other parts of the body, sometimes involving the mucosa . The damage starts from a small or a few reddish, dark red or purple red patches, which are irregular in shape, with clear boundaries and no higher than the leather surface. The telangiectasia can be seen, and the partial or complete fading of the pressure is smooth. As you age, the color darkens and turns purple. 40% of patients will gradually expand their lesions. They can thicken and develop nodules before the age of 40, and are prone to bleeding after trauma. Port wine stains are the flattened and rarely bulging plaques composed of numerous post-expanded posterior venules, which are congenital posterior venule malformations. The area of the lesion increases with the growth of the body and does not subside.

Photodynamic Therapy, also known as Photodynamic Therapy (PDT), is a new selective treatment technology for (vascular) proliferative lesions that developed in the late 1970s and has developed rapidly in recent years. This therapy is another new treatment that is under research and rapid development after surgery, radiotherapy, chemotherapy and immunotherapy. It has become one of the most active research fields in the world of cancer prevention science. Photodynamic interaction refers to the function or morphological change of organism cells or biomolecules under the action of photosensitizers, which leads to cell damage and necrosis in severe cases, and this effect must involve aerobic participation, so It is called photosensitization-oxidation. It is called photo-sensitization chemically. It is called photodynamic action in biology and medicine. Photodynamic therapy is called photodynamic therapy. In recent years, with the successful development of new photodynamic therapeutic drugs and the improvement of laser equipment technology, PDT has ushered in an unprecedented development peak. At the same time, PDT is also used for non-tumor diseases such as genital warts and cowhide. Treatment of diseases such as sputum, port wine stains, rheumatoid arthritis, fundus macular degeneration, and restenosis after angioplasty. China has started relatively late in the research and development of light source and equipment systems for photodynamic therapy, and has few varieties, which can no longer meet the needs of the growing photodynamic medicine.

As a technology-based company specializing in the research and development and application of optoelectronic technology in the field of medical devices, the applicant has been working on photodynamic therapy instruments and equipment technology for many years, focusing on how to apply semiconductor composite narrow spectrum in photodynamic therapy for various diseases.

Design a dedicated narrow-spectrum light source substrate to make full use of the excellent wavelength selectivity of semiconductor narrow-spectrum light sources to form different narrow-band composite spectra to meet the optimal spectral requirements for different photosensitizers (photodynamic therapy drugs). To achieve the best results.

Because photodynamic therapy of port wine stains requires accurate instrument parameters, accurate use parameters during treatment, stability and reliability of light source, it is directly related to the safety and effectiveness of treatment, and most cases cannot be cured at one time, so it is necessary to The patients made detailed and complete records from the initial treatment to the final treatment of various indicators, treatment parameters, treatment effects.
