Description
Technical field
The present invention relates to medicinal intelligent electronic device fields, and in particular to a kind of intelligence for the supervision of hand hygiene compliance is eventually
End.
Background technology
Medical staff's hands Carried bacteria is nosocomial infection main source.Direct or indirect transmission by hand bacterium causes to infect
Account for more than the 30% of hospital infection.Medical worker, which strictly washes one's hands, can reduce carrying pathogen, effectively cut off direct contact infection.
Disease prevention and control center of the U.S. is in October, 2002 issue medical institutions hand hygiene guide, it was confirmed that hand hygiene it is effective
Property, and for pointing out other opposite hospital infection management measures, hand hygiene be reduce hospital infection most directly, it is most simple, most pass through
Ji and one of most effective measure, play great function in hospital infection, and rate of hospital acquired infection can be made to decline 50%.
Relatively low hand hygiene compliance rate is China's situation of all-level hospitals common problem.How to effectively improve hospital's hand hygiene according to
It is the problem of hospital sensing control manager extremely pays close attention to from rate.Hospitals at Present mainly by regularly training, medical staff self about
Beam sets traditional management methods such as infection assistant director, does not supervise significantly more efficient measure for hand hygiene, consumes substantial amounts of
Manpower and materials considerably increase the invisible cost of hospital.
On the other hand, there are also some for the product or technology for improving hospital's hand hygiene compliance rate.For example China is specially
Profit《A kind of medical treatment hand hygiene compliance intelligent monitoring system》（CN 105139320 A）With《It is a kind of for medical act management
