Description
Technical field
The invention belongs to laser sterilization technology, specifically refer to a kind of based on ultraviolet with infrared double-waveband for medical apparatus and instruments
Degerming handheld portable semiconductor laser disinfection system.
Background technology
As the continuous development of modern emergency medicine, critical patients synthesis diagnoses and treatment are more and more, success rate is given treatment to
Also improving constantly.But, with the extensive application and the emergence of Resistant strain 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 intensive care unit(ICU) (intensive care uni, t ICU) is accepted for medical treatment
Weight, receive invasive emergency measures many features such as so as to the prevalence of hospital infection is high compared with public ward 3 ~ 18 times, is close to 50%.Root
According to updated statisticss in 2014, Nei Ge great section office of hospital intensive care unit, particularly neurosurgical ICU, ICU diseases
The intensive care unit that the severe crisis such as room patient concentrates, kainogenesis after being admitted to hospital due to nosocomial infection, contacts pathogen in hospital
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 etc. mostly；Two is same relative
The several wounded, patient are treated simultaneously in confined space；Three is that sick and wounded's infection rate is above ordinary circumstance in the case of two kinds, infects
Often lead to pernicious consequence.
And the infection predicament under both the above material circumstance is solved, the pathogen for first having to control medical apparatus and instruments is passed
Broadcast.The conventional method for adopting mainly has the autoclave sterilization of medical apparatus and instruments, the sterilization of chemical agent, the photograph of Ultraluminescence at present
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 is added frequently, medical apparatus sterilization relies on existing side
Method, mainly ultraviolet lighting and air filtration, it is difficult to maintain higher aseptic condition, nosocomial infection to be difficult to eliminate.
Applied research of the laser in medical science gradually rises in recent years.Laser sterilization technology is compared with ordinary optical sterilization technology
