Description

The SARS protecting instrument

The utility model relates to a kind of SARS protecting instrument, particularly a kind ofly prevents that SARS virus is from the respiratory infectious safeguard.

Present research thinks that SARS mainly is by short distance droplet transmission, contact patient respiration road secretion and close contact transmission.Because patient talk, cough, sneeze, breathing the spittle that is brought out can be with airborne particle suspension in the middle of air, the people of health breathes and thisly has viral air and will be infected.After healthy people's hand touched the object of SARS virus in addition, catch eye-catching eyeball, nose, mouth can be infected equally.Wearing common mouth mask and can not prevent the propagation of SARS fully, mainly is to have following problem, and the number of plies that the first wears masks is few, is suspended in airborne viruliferous particulate, can directly enter the human respiratory tract from the screen pack of mouth mask; Its two be the institute number of plies that wears masks more, human body respiration is difficulty, because the number of plies is more, add that the gas that human body is breathed out slowly soaks mouth mask, the air of being breathed is difficult to the filtration of process mouth mask and enters respiratory tract, and the space that air will contact with face from the space and the mouth mask of nose both sides enters respiratory tract; It three is that institute wears masks and nose, tight-lipped subsides, in case the virus in the mouth mask ingress of air, virus directly immerses respiratory tract by mouth mask; The viral gas that has that its four patient SARS is breathed out does not pass through effective sterilization, and the meeting contaminated air causes healthy people infected; Its five be the air institute that can not breathe out to patient SARS and patient suspected in spite of illness poison collect, provide medical science to detect.

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of route of transmission that effectively prevents SARS is provided, and mainly the people to health provides through filtering, and the breathe air of liquid sterilization, filtration makes SARS can not pass through respiratory infectious; After the air that patient SARS breathed carried out sterilization, filters, to the gas institute that breathes out in spite of illness poison collect, can detect the malicious in spite of illness situation of patient expired gas at any time, the medical diagnosis foundation is provided.Then the gas that patient breathed out is carried out liquid sterilization, filtration, the gas that patient breathed out just can contaminated air like this, effectively cuts off the route of transmission; The air that the SARS patient suspected is breathed carries out sterilization, filter after, to the gas institute that breathes out in spite of illness poison collect, detect whether malicious in spite of illness situation of patient expired gas, further make a definite diagnosis and whether infect SARS, the gas that the SARS patient suspected is breathed out carries out liquid sterilization, filtration then.Prevent that SARS from passing through respiratory infectious.

The utility model SARS protecting instrument is achieved in that it comprises air intake filter, nose, mouth, eye protective cover, and the collection virus device, discharge filter is formed.Air intake filter comprises the inlet air filtration net, miniature asepwirator pump, and liquid filter, air inlet pipe, air control valve is formed.The inlet air filtration net can be made of gauze, according to circumstances changes; Miniature asepwirator pump, available dry cell or directly plug-in source use; Air intake filter, the filter liquide of adorning can be as required, the sterilizing liquid of packing into human body being safe from harm; Be equipped with air control valve on the air inlet pipe, can regulate the size of air according to the level of comfort of human body respiration.Nose, mouth protective cover connect air inlet pipe, escape pipe, eyeshade, clip.The collection virus device connect blast pipe to breath institute in spite of illness poison collect, provide medical science to detect.Discharge filter links to each other with the collection virus device, and breath is carried out sterilization, liquid filtering, and the exhaust gas filter net can be made of gauze, according to circumstances changes.

The utility model SARS protecting instrument operation principle is during use, to open the switch of miniature asepwirator pump, air enters liquid sterilization, filter through behind the screen pack, because filter adopts particular design, utilize the effect of air pressure difference, make air reach the purpose of sterilization, filtration.Liquid volume that air intake filter is adorned is less, leaves enough spaces, and sterilizing liquid can not contact human body.The liquid that filter is adorned is selected liquid sterilization, filtered fluid that human body is safe from harm for use.Through the air of filtration, sterilization,, can regulate the size of air according to the level of comfort of human body respiration by the air inlet pipe of control valve is arranged.The air that enters through air inlet pipe makes human body natural's breathe air by nose, mouth protective cover.Not intact when the absorption of air that enters nose, mouth protective cover, when also having surplus air, because action of pressure, the logical blast pipe of remaining air is got rid of.Simultaneously the gas institute that human body is breathed out in spite of illness poison collect, detect and diagnosis for medical science, further improve patient's SARS treatment measure and making a definite diagnosis to the SARS patient suspected.The gas of discharging through the collection virus device is through discharge filter sterilization, filtration.Discharge filter is equipped with liquid fungicide, and the gas after liquid sterilization filters refilters by the exhaust gas filter net, and screen pack can be made of gauze, according to circumstances changes, thereby makes SARS can not pass through respiratory infectious, avoids healthy people infected.

The utility model SARS protecting instrument advantage is to prevent that virus from from respiratory infectious, providing aseptic air to healthy people; Patient expired gas to SARS carries out sterilization, filtration, makes air not contaminated; Virus to the SARS patient suspected is collected, and helps further to make a definite diagnosis, and simultaneously the gas of breathing out is carried out sterilization, filtration, prevents the propagation of virus.Be applicable to medical worker and healthy people's self-protection; Be applicable to patient SARS and SARS patient suspected, prevent the diffusion of virus.
