Abstract
The invention discloses a rotating mirror scanning dual waveband semiconductor laser sterilization system for a medical device, which comprises an infrared semiconductor laser, an ultraviolet semiconductor laser, optical fiber collimators, a zooming coupled lens assembly, an infrared beam scanning rotating mirror and an ultraviolet beam scanning rotating mirror. The system can be applied in various modes and occasions and can make important contribution to reduce a fatality rate and a disability rate and restore health as soon as possible in the field of medical treatment and intensive care infection prevention and treatment; the system achieves quick and thorough sterilization and has high efficiency by adopting an intense laser sterilization mode and integrating the advantages of a strong heating effect of an infrared laser and a strong protein molecular ionization damage effect of an ultraviolet laser; and the system is portable and reusable, is not contacted with a human body, has no obvious direct or indirect influence on the human body and is convenient to realize.
Description
technical field [0001] The invention belongs to laser sterilization technology, and specifically refers to a rotating mirror scanning semiconductor laser sterilization system based on ultraviolet and infrared dual-bands for medical equipment. Background technique [0002] With the continuous development of modern emergency medicine, there are more and more comprehensive diagnosis and treatment methods for critically ill patients, and the success rate of treatment is also increasing. However, with the widespread use of antibiotics and the continuous emergence of drug-resistant strains, nosocomial infection has become an important issue of concern to the medical community. The prevalence of nosocomial infection in intensive care uni (t ICU) is 3-18 times higher than that in general wards, close to 50%, due to the characteristics of severe illness and more invasive rescue measures in patients admitted to intensive care unit (t ICU). According to the latest statistics in 2014, ...
