Description
Technical field
The present invention is the protector of a kind of bacterium for protecting medical personnel to be carried from patient or virus infection, specific next
Say it is that one kind is directed to division of respiratory disease clinic, prevent the disinfection isolating device of medical personnel's cross-infection.It is related to purification of air to set
Standby technical field.
Background technology
Having broad medium to report every year, multiple places are deep in the world is encroached on by virus spread, such as SARS, Ebola, first
Type H1N1 influenza viruses etc., large area propagates the fear that can all cause people to virus spread each time, therefore to respiratory tract infection
The prevention and control of disease and significant problem urgently to be resolved hurrily in recent years.The infection sources of respiratory infectious disease is predominantly carried and infected
The patient of encephalapthy agent, and the circulation way of respiratory disorder pathogen mainly has four kinds：Direct contact, mediate contact, (short distance
From) droplet transmission and (short distance and long range) air borne.According to literature review, air borne short-distance and medium-distance propagate than it is long away from
Menace is had more from propagating, therefore it is significant to study pathogen propagation of the human peripheral about in 1.5m.Around patient
The propagation of pathogen make it that medical personnel are easily infected by patient during seeing a doctor, and have many medical personnel by disease every year
People infects ill or even died, and the isolating and protecting of division of respiratory disease medical personnel is particularly important.How in existing clinic condition
Under without Overall Reconstruction (being such as transformed into negative pressure isolated consultation room or ward), and only increase a set of isolating device can reach it is aobvious
It is then key issue of the prior art to write effect.
