The semiconductor laser disinfection system of infrared double-waveband.
Background technology
As the continuous development of modern emergency medicine, critical patients synthesis diagnosis and treatment method are more and more, success rate is given treatment to
Also improving constantly.But, with the extensive application and the emergence of antibody-resistant bacterium of antibiotic, hospital infection has become medical science
The major issue of boundary's concern.Because there is the state of an illness in the patient that CICU (intensive care uni, t ICU) is accepted for medical treatment
Weight, receive invasive emergency measures it is many features such as so as to the illness rate of hospital infection is high compared with public ward 3 ~ 18 times, close 50%.Root
According to updated statistics in 2014, Nei Ge great section office of hospital intensive care unit, particularly neurosurgical ICU, ICU was sick
The intensive care unit that the severe crisis such as room patient concentrates, kainogenesis after being admitted to hospital due to nosocomial infection, contacts in hospital pathogen
Caused infection becomes nosocomial infection, and caused serious respiratory tract infection becomes causes conditions of patients to deteriorate the important of even death
One of reason.
Comprehensive trauma care and intensive care infect situation occurred frequently, it can be found that existing between the two following
The general character of aspect：One is that patient receives iatrogenic invasive treatment such as operation, tracheotomy mostly；Two is same relative
The several wounded, patient are treated in confined space simultaneously；Three is that sick and wounded's infection rate is above ordinary circumstance in the case of two kinds, is infected
Often lead to pernicious consequence.
And the anti-infective predicament under both the above material circumstance is solved, the pathogen for first having to control medicine equipment is passed
Broadcast.At present the conventional method for adopting mainly has the autoclave sterilization of medicine equipment, the sterilization of chemical agent, the photograph of Ultraluminescence
The aggregate measures such as penetrate.But, under contingency condition, the rescue and treatment of the wounded is pressed for time, workload is big, condition is limited, often because sterilizing
Equipment is huge heavy, and chemical agent carries limited amount, and approach described above is required to the long period and could work, and does not reach
Sterilization is required.In hospital intensive care unit, personnel, patient's circulation are added frequently, medical apparatus sterilization relies on existing side
Method, mainly ultraviolet lighting and air filtration, it is difficult to maintain higher germ-free condition, nosocomial infection to be difficult to eliminate.
Application study of the laser in medical science is gradually risen in recent years.Laser sterilization technology is compared with ordinary optical sterilization technology
