LED medical effect: 2 hours to kill Helicobacter pylori

"Light emitting diode (LED) the new usage is not only lighting purposes". In November 30, 2005 ~ December 1st held in Tokyo "LEDEX Japan 2005", Taguchi Toma Research Institute of full-time professor at Yamaguchi University in Japan published LED medical research achievements, also stressed that due to the diagnosis and treatment by LED, so the medical device market will expand LED. Taguchi knowledge cluster in Ube Yamaguchi county area to create the project (Knowledge Cluster: the Japanese Ministry of education is one of the projects, to local government led by universities and research institutions as the core, research institutions and enterprises rely on the development of international competitiveness of technological innovation, research) responsible for the white LED and UV LED medical technology.

"Lighting white LED is not a panacea in the medical field"

In terms of the use of medical LED, Taguchi mentions the use of an endoscope. Taguchi said that the white LED light source mirror through endoscope (near ultraviolet LED chip developed by using Taguchi), can be faithfully reproduced the object color, and the endoscope front end is equipped with near ultraviolet LED, pathogenic bacteria can also repel the body.

In this paper, a new type of fluorescent material, which can be converted into orange, yellow, green and blue by near ultraviolet light on the near ultraviolet LED chip, is used to obtain 4 kinds of fluorescent materials. If the "white index (evaluation and spectral differences between the sun and the sun, consistent 0)", the white LED is 1.03, 8.21 is far less than the combination of blue chip and LED yellow phosphor materials of ordinary white LED, so the spectrum and is close to the sun. And this index is also 5.31 of the fluorescent lamp and HID lamp (high intensity discharge lamp) of the small to 3.27. The industry generally believes that if the white LED luminous efficiency of more than 100lm/W, the market for white LED lighting appliances will rapidly expand, which will begin to develop a white LED with high output power. However, only the white LED on the brightness requirements are not omnipotent (Taguchi). Taguchi believes that, and can not be sure that the ordinary white LED has met the needs of the medical front line, only to meet this demand, the market for medical devices white LED can quickly expand.

Helicobacter pylori

In the near ultraviolet light on the therapeutic effect of pathogenic bacteria, it has been proved by experiments that the use of near ultraviolet LED UV irradiation can eliminate Helicobacter pylori (Helicobacter Pylori), etc.. Helicobacter pylori can cause chronic gastritis and gastric ulcer. It is said that by the use of glass culture of Helicobacter pylori irradiation 2 hours of the central wavelength of 400nm ~ 410nm light, the eradication of Helicobacter pylori. Under normal circumstances, in order to eliminate Helicobacter pylori, the need for the use of drugs for days of treatment, and the use of near UV LED, just a short time to complete the treatment of light irradiation.

If exposure to ultraviolet light in the body, there is a risk of adverse effects on the body cells. In this regard, Taguchi said that if the use of a wavelength of about 400nm near visible light near ultraviolet light, there will be no adverse effects.
