Abstract
The utility model relates to a dual-channel mask for disease control and prevention. The dual channel is provided with an air inlet valve and an air outlet valve. The dual-channel mask for the disease control and prevention can be used for overall protecting to the mouth, the nose, the eyes and the face, and controlling transmission of infectious disease. The dual-channel mask for the disease control and prevention is characterized in that a mask body is provided with a sealing side strip, a sealing parting strip, and a binoculus convex cavity, a filtering shell and a front cover are arranged on the front portion of the mask body, a parting plate, an air-exhaling cavity and an air-inhaling cavity are arranged in the filtering shell, an air-inhaling filtering layer and an air-inhaling door are arranger in the air-inhaling cavity, the air-inhaling door is provided with an air-inhaling valve, an air-exhaling filtering layer and an air-exhaling door are arranged in the air-exhaling cavity, and the air-exhaling door is provided with a air-exhaling valve. Due to the fact that the dual-channel mask for the disease control and prevention is provided with two channels of inhaling air and exhaling the carbon dioxide, a mist cannot occur, the sight is not affected, the inhaling air can be fresh, the exhaling carbon dioxide cannot reflow any more, the problems of insufficient oxygen inhalation and difficult breathing of a common mask are solved, the chances of infecting infectious diseases are reduced, and spread of the infectious diseases can be better controlled and prevented. The dual-channel mask for the disease control and prevention has the advantages of being reasonable, practical, novel in structure design, and suitable for popularizing usage in all levels of infectious disease hospitals and epidemic prevention and disease control departments.
Description
Affiliated technical field
The utility model relates to a kind of control and prevention of disease face shield, particularly includes the binary channels of turnover valve, and counterpart, nose, eye and face have comprehensive protective action, can control a kind of binary channels control and prevention of disease face shield of infectious disease transmission; Being fit to infectious hospitals at different levels, epidemic prevention and control and prevention of disease department promotes the use of.
Background technology
At present, staff and the control and prevention of disease personnel in infectious disease and slight toxic and harmful place, it is the most common that what wear is mouth mask; But because the air that common mouth mask sucks and the carbon dioxide of exhalation are passages, and all use same filtration channel; Like this, the one, the carbon dioxide of breathing out is residual in filter course, sucked back human body again, it is slightly long to wear the common mouth mask time, and it is not enough to cause oxygen to suck, and the lighter is uncomfortable, and operating efficiency is low; Severe one is felt dizzy, expiratory dyspnea.The 2nd, common mouth mask has only covered mouth, nose, and eyes are not had protective action.Toxic and harmful is also very important to the invasion and attack of eyes mucous membrane, is operated in the medical personnel of infectious hospital, faces the chance that various communicate illness infect; As: the saliva that the patients such as hepatitis B, hepatitis C, AIDS, venereal disease, SARS are splashed, blood etc. also consist of greatly threat to medical worker's health.Only wear common mouth mask, can't protect the eye mucous membrane outside mouth, the nose to be infected.Therefore, above problem is the problem of epidemic prevention and control and prevention of disease personnel thinking.
Summary of the invention
In view of the above problems, the utility model proposes a kind of binary channels control and prevention of disease face shield, be provided with the binary channels of turnover valve, the again backflow of the waste gas of can avoiding giving off carbon dioxide sucks; Counterpart, nose, eye have protective action, the propagation of better prevention and control infectious disease; Being fit to infectious hospitals at different levels, epidemic prevention and control and prevention of disease department promotes the use of.
The technical scheme that the utility model adopts is: binary channels control and prevention of disease face shield has mask body, frenulum; It is characterized in that: the protruding chamber of eyes that has sealing edge strip, its top to have sealed parting strip and sealing strip bar to form around the mask body rear portion; The cavity that the mask body front portion has filter housing and population, nose to form, filter housing has protecgulum; Discharge chamber, suction muffler that baffle for separating is arranged in the filter housing; There is air-breathing filter course the front in the suction muffler, and air-breathing filter course back has air-breathing door to communicate with cavity, and air-breathing door has the inlet valve of inwardly opening; There is the exhaust gas filter layer front in the discharge chamber, and its back has the door of expiration to communicate with cavity, and the door of exhaling has the outlet valve of opens outward; There is ear sealing edge strip back, and ear is porose, and the hole connects frenulum.
This binary channels control and prevention of disease face shield, protecgulum can be full aeration types.
This binary channels control and prevention of disease face shield, protecgulum can be provided with air grid.
This binary channels control and prevention of disease face shield, protecgulum can be provided with passage.
This binary channels control and prevention of disease face shield, air-breathing filter course, exhaust gas filter layer can according to pollution condition, be opened protecgulum and be changed at any time; Its air-breathing filter course, exhaust gas filter layer can be selected different filtering materials according to different workplaces, and the infection particle diameter that it can protect can be that bacterium or virus propagation are decided according to the protection place.
This binary channels control and prevention of disease face shield is provided with the binary channels that passes in and out valve, and the air of suction and the carbon dioxide of exhalation are two passages; And, also be provided with outlet valve, inlet valve; It is external fresh air that inlet valve can make the air of suction, and outlet valve can make the unidirectional discharge of the carbon dioxide of exhalation, CO 2 waste gas residual in the exhaust gas filter layer can not be refluxed again suck back human body; Solved that to wear the common mouth mask time slightly long, it is not enough to cause oxygen to suck, and makes uncomfortablely, and operating efficiency is low, dyspneic problem.Sealed parting strip makes the hot gas of characteristics of contaminated respiratory droplets can not enter the protruding chamber of eyes; Make not produce fog in it, do not affect sight line.And the utility model counterpart, nose, eye and face have comprehensive protective action, have solved the invasion and attack problem of toxic and harmful to the eyes mucous membrane; Reduced the chance that medical personnel infect various communicate illness, the propagation of better prevention and control infectious disease; The utility model reasonable in design, practicality, novelty are fit to infectious hospitals at different levels, epidemic prevention and control and prevention of disease department and promote the use of.
