The use of LED light source in medicine
The use of light to cure human diseases is a very old method. Humans have used sunlight to cure diseases as early as a long time ago. As a new type of light source, LED lamp beads are gradually used in medicine and play an active role.
Reducing Inflammation A series of studies have shown that LED lamp beads have anti-inflammatory effects. The study found that the 635nm LED lamp pearl light can suppress the fibroblasts in the gums to release the inflammatory mediator-prostaglandin E2 (PGE2), thereby reducing the inflammatory response of the gums. The use of LED lamp beads to illuminate early before radiotherapy for breast cancer patients can reduce the side effects of radiotherapy. Before the pulsed dye laser treats skin photoaging, if the LED lamp bead is used to illuminate in advance, it can reduce the skin erythema, swelling and pain caused by the dye laser.
Promote the healing of wounds The LED lamp beads of various wavelengths in the near infrared can promote the growth of epithelial cells after trauma and promote the healing of wounds.
Keloid is a skin disease that affects beauty and is difficult to treat clinically. It is caused by excessive proliferation of connective tissue after skin damage. Patients often have a scarring constitution. Clinically, it begins as a small and firm red papule, which gradually enlarges and develops round, oval or irregular scars, which are higher than the skin surface and expand outward in a crab-like shape. The skin is lubricated and shiny, and may be accompanied by Pain, itching, etc. Clinical treatment is difficult and the effect is not satisfactory. Some studies have found that LED lamp beads can significantly improve the pain, itching and other discomfort of patients, flatten scars, and have the advantage of non-invasiveness.
In addition, LED lamp beads can also be used as a UV-free phototherapy device for photodynamic therapy, treatment of hair loss, reduction of skin damage after UV exposure, and so on. All in all, as a new type of light source, LED lamp beads have been gradually used in dermatology. With the continuous innovation of LED lamp beads and the research on the mechanism of LED biological effects in medicine, the use of LED lamp beads in medicine will be Has unlimited prospects. At the same time, LED lamp beads have high safety and can be used as home medical equipment.
