The invention discloses a handheld dual-wave-band semiconductor laser sterilizing system for a medical appliance. The handheld dual-wave-band semiconductor laser sterilizing system comprises an infrared semiconductor laser, an ultraviolet semiconductor laser, optical fiber collimators, and a handheld device which is connected with the optical fiber collimators through optical fibers; a sterilized medical appliance is sterilized by an operator holding the handheld dual-wave-band semiconductor laser sterilizing system. According to the handheld dual-wave-band semiconductor laser sterilizing system, the medical appliance can be sterilized at various angles for a reasonable time by conducting all-around scanning on the surface of the medical appliance and a relative object through the handheld device; the system can be applied in a plurality of modes and places, and can make great contributions to reducing mortality and disability rate and recovering health as soon as possible in the field of medical treatment and intensive care infection control and prevention; a dual-wave-band strong laser sterilization mode is adopted, and meanwhile, the advantages of strong heating effect of infrared laser and strong protein molecule ionization damage effect of ultraviolet laser are integrated and utilized, so that the system can sterilize quickly and thoroughly, and is high in efficiency.
Description
technical field [0001] The invention belongs to the laser sterilization technology, and specifically refers to a hand-held portable semiconductor laser sterilization system for medical device sterilization based on ultraviolet and infrared dual-wave bands. 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 statis...
