The main market for LED replacement devices is the application of low intensity laser therapy and fluorescent light therapy. As an effective treatment method, phototherapy has been widely used in clinical and engineering. Its theoretical basis is that biological tissue absorbs light energy and converts it into heat energy and chemical energy, which leads to a series of chemical reactions in the body. These reactions include photolysis, photooxidation, photopolymerization and photosensitization. As a new type of light source, LED has been gradually recognized by people as a biological effect of light, which is gradually being applied in medicine and playing a positive role.
Red light therapy mainly USES thermal effect. The body's absorption of infrared light leads to increased body temperature, local or systemic vascular dilatation, accelerated blood flow rate, and promotes metabolism and cell proliferation, with anti-inflammatory and analgesic effects. May cause the blood white blood cell total number and the eosinophil reduces, the improvement growth metabolism, reduces the blood sugar, promotes the ovary corpus form. Blue-violet light is the antagonist of the physiological action of red orange light, can prevent insulin hypoglycemia, can bleach bilirubin in blood to treat neonatal jaundice. Ultraviolet light mainly USES high-energy radiation sterilization, treatment of various bacteria caused by skin diseases.
LED phototherapy technology dynamic
In January 2018,
The university of Rhode Island (URI) has developed a medical jumpsuit that combines LED light therapy so that newborns with jaundice can receive light therapy at home, and doctors can receive their physiological data remotely. The wearable device, called Jaundice Suit, USES hundreds of LED lights to cover the baby's arms, legs and torso. It can be connected to the Internet and collect physiological data of the human body. The internal LED lights can also be controlled remotely.
In November 2017,
The Swiss federal institute of material testing and development (EMPA) in early November last year for jaundice infants develop wearable LED phototherapy pajamas, use a special way of weaving, let the optical fiber and textile technology, combining with the LED is set to the light source, optical fiber light guide control braided Angle, keep light wavelength at around 470 nm, and can shine into the skin.
