Description
Technical field
It the utility model is related to tuberculosis prophylaxis field, specifically a kind of active antibiotic draught biology for tuberculosis prophylaxis
Protective mask.
Background technology
Once extensive respiratory infectious disease epidemic situation, such as tuberculosis, SARS, height had been broken out repeatedly in mankind's public health history
Pathogenic avian influenza, Influenza A H1N1 etc..Respiratory infectious disease has spread speed fast, easy by the spittle and air borne
The characteristics of touching group is wide, the incidence of disease is high, very big threat is caused to public health and social stability, wearing protective mask can block
Pathogenic microorganism invades human body, is preventing respiratory infectious disease, protects the effective means of health of masses.The number of the World Health Organization
According to display, China is the tuberculosis country occurred frequently for being only second to India in the world, and tulase resistance case load then occupies first place in the world.
Tuberculosis patient, family members, medical personnel are chronically among the spittle and air ambient that carry tuberculosis germ, have high-risk cause a disease
Risk.The tuberculosis prevention and treatment measure that China implements at present is " the Stop TB strategy " based on tactful, its core by " DOTS "
Heart spirit is to prevent trouble before it happens.Therefore for tuberculosis patient and its surrounding exposed population group, by wearing biological protective mask
Tuberculosis pathogeny can be effectively blocked to propagate, it is ensured that popular public health security.
Biological protective mask refers to the mouth mask that protection is provided personnel's respiratory tract under biological pollution environment, can by its function
It is divided into passive-type biological protective mask and active antibiotic draught biological protective mask.Passive-type biological protective mask is generally to make at present
A kind of protective mask, the physical particles thing in air or harmful pathogen are mainly filtered out in a manner of physical filtering.It is actively anti-
Bacterial type biological protective mask refers to add certain antimicrobial component in mask material, assigns mouth mask active antibacterial functions.Biology is anti-
Retaining cover can reach 95%-99% to the filter efficiency of particulate matter, it could be theoretically argued that it can provide people effective protection,
But absorption on passive-type biological protective mask have communicable pathogen may spread again, to environment and it is artificial into
Secondary pollution.In order to prevent to be attached to superinfection caused by the pathogenic microorganism on mouth mask spreads again, have and actively sterilize
The mask material of function and its application are increasingly taken seriously, and are actively sterilized it assures that mouth mask plays while pathogen is filtered
Function.
It can suppress or kill the protective mask of pathogenic microorganism, the emphasis and core of its development are the filter of mouth mask
Core material and antiseptic, the simple effective method that antiseptic is to confer to mouth mask antibacterial functions is added on filter material, due to most
The toxic side effect to human and environment be present in the chemical antiseptics of number, thus a new generation have the mouth masks of active antibacterial functions still up for
Further development, to meet the purpose of the multi-functional characteristic requirements of biological protection and reliable safety.
In the exploitation of protective mask material for core, activated carbon application is relatively broad.The main component of activated carbon is carbon, and it is
A kind of porous solid carbonaceous of black, its specific surface area is in 500~1700m2/ g, there is very strong absorption property.Use activated carbon
Isolation filtering material is served as, can effectively adsorb the trace toxic gas in air, while isolates removal such as Escherichia coli, yellow Portugal
The droplet transmission bacterium such as grape coccus, pyogenic baeceria, tulase, suppress infectious respiratory disease caused by viral source and propagate.But
Usually activated carbon is based on physical absorption used in general mouth mask, limited sorption capacity, and easily causes secondary pollution.
