Specific Electromagnetic Wave Therapeutic Apparatus (TDP) has the function of assisting anti-inflammatory, analgesic, improving circulation and enhancing immunity. Specific electromagnetic wave therapeutic device (TDP) is also known as specific electromagnetic spectrum radiator, its radiation plate is composed of special enamel coating, the electromagnetic waves radiated have the role of promoting enzyme effect, thermal effect, and enhance information flow and other biological effects. TDP has electromagnetic wave effect and thermal effect, its electromagnetic wave can assist in improving local blood circulation, accelerate metabolism, promote the growth of granulation tissue, and then play a role in anti-inflammatory and accelerate the role of tissue repair, at the same time, TDP to improve the immune function of the body, antispasmodic and analgesic have a certain therapeutic effect. However, TDP is only a kind of auxiliary treatment means, purely relying on TDP can not cure the disease, still need the doctor’s diagnosis and treatment.
