British researchers have recently developed a new technology for harmless light disinfection that can be used 24 hours a day in the ward, which is not only harmless to the human body, but also completely eliminates the dead corners.
Researchers at the University of Strathclyde in the UK reported in a new issue of the Journal of Hospital Infections that the technology they developed was called the "High-intensity Narrow-spectrum Light Environment Disinfection System", using visible light. Causes some molecules in the bacteria to change, producing toxic chemicals that kill the bacteria.
Professor John Anderson, who participated in the study, said that this light can kill a variety of bacteria such as methicillin-resistant Staphylococcus aureus and Clostridium difficile. What is important is that it is harmless to the human body and can be continuously irradiated.
According to reports, the disinfection light emitted by this system is purple, but the researchers have added other lighting devices to the system, so that the entire system emits white soft light, which can be used with the hospital's conventional lighting system.
Previously applied more light disinfection technology is UV disinfection, ultraviolet light is not visible light, and long-term exposure is harmful to the human body.

Under normal circumstances, disposable Masks are replaced once every 8 hours, and cannot be reused. Disposable masks are made of more than three layers of 28 g non-woven fabric; the bridge of the nose is made of environmentally-friendly all-plastic strips, without any metal, with breathable, comfortable, especially suitable for electronics factories, daily use. The disposable medical surgical mask can prevent respiratory tract infection to a certain extent. It is made of two layers of non-woven fabric and filter paper. It consists of two layers of fiber non-woven fabric, which is professionally used for medical treatment. More than 99% of the filter bacteria can be filtered by ultrasonic welding.
