TDP (Thermal Design Power): It is the Chinese Pinyin abbreviation of "Specific Electromagnetic Spectrum". TDP therapeutic device (i.e. TDP magic lamp) is widely used for: cough, asthma, bronchitis, emphysema, pneumoconiosis, waist and leg pain, frozen shoulder, rheumatoid arthritis, synovitis, sciatica, cervical spondylosis, hyperlipidemia , coronary heart disease, arteriosclerosis, various fracture healing, postoperative wound healing, various sprains and contusions, and the treatment of various gynecological inflammations and pains.
PDT: Photodynamic Therapy (PDT) is a new technology that uses photodynamic effects for disease diagnosis and treatment. The basis of its action is the photodynamic effect. This is a photosensitization reaction accompanied by biological effects involving oxygen molecules. The process is that laser irradiation of a specific wavelength excites the photosensitizer absorbed by the tissue, and the excited state photosensitizer transfers energy to the surrounding oxygen to generate highly active singlet oxygen, which interacts with adjacent organisms. Oxidation reactions occur in macromolecules, resulting in cytotoxic effects, which can lead to cell damage or even death.
One of them uses electromagnetism and the other uses light to treat. Photodynamic therapy devices are generally used for beauty or sterilization and anti-inflammation, and are characterized by minimal invasiveness. Electromagnetic waves treat or supplement energy through trace element effects, enzyme system effects, information effects, electromagnetic wave effects, and thermal effects to promote growth, development, reproduction, and repair.
