Description
Technical field
The utility model belongs to the dustproof protection from fumes protective cover of a kind of anti-virus.
Background technology
Various well-known or nameless viruses are greatly endangering human health, and especially nameless new virus does not have antibody and do not research and develop under the prerequisite of new antiviral drug at human body, very easily causes human mortality.Passive during this period prevention is commonly used for antiviral effective means.For example isolate a patient and promotion and patient Close contacts wear masks etc.There is this viral communication rapid and severe, even if wear the also infringement of unavoidable virus of double-deck mouth mask.Should at first block viruliferous patient theoretically and distribute virus, secondly be to prevent that virus from entering human body.But at present the restive patient of mouth mask distributes virus, though mouth mask can stop patient expired part virus can not kill virus, patient in oxygen uptake or in a minute time the especially need take that mouth mask is easier to cause viral diffusion.Simultaneously, the human body mouth and nose are breathed by mouth mask, the easier human body that enters of the virus on it.On the other hand, wear masks and also be difficult for doctor's interrogation and exchange with patient.
Summary of the invention
The purpose of this utility model is the dustproof protection from fumes protective cover of a kind of anti-virus of design, makes its anti-virus, dustproof, protection from fumes and gas defence effectively, also has the function that makes things convenient for oxygen uptake and conversation.For this reason, the utility model is provided with exhaust check valve, breather cheek valve, microphone and oxygen air inlet on the mouth and nose cover body, the exhaust check valve tracheae that runs in, the other end of blast pipe is arranged in the filtered fluid of exhaust gas filter box, filtered fluid upper end in the exhaust gas filter box is provided with the exhaust gas filter pipe, breather cheek valve taps into tracheae, the port of export of the air-breathing filter cartridge of another termination of air inlet pipe, the S-shaped crooked shape of air inlet pipe, microphone connects loudspeaker by lead, and it is external that the oxygen filtration interface of oxygen air inlet is positioned at oronasal mask.The said structure design has realized the purpose of this utility model.
The utility model has the advantages that effectively anti-virus, dustproof, protection from fumes and gas defence, also have the function that makes things convenient for oxygen uptake and conversation.And it is little, simple in structure also to have volume, not fragile, the low and advantage easy to use of cost.
Description of drawings
Figure is a structural representation of the present utility model
Specific embodiments
As shown in the figure, a kind of anti-virus protection from fumes protective cover that prevents dust is made up of mouth and nose cover body 2 and sealing strip 1.The mouth and nose cover body is provided with exhaust check valve 5, breather cheek valve 3, microphone 4 and oxygen air inlet 16.The exhaust check valve tracheae 6 that runs in, the other end of blast pipe is arranged in the filtered fluid 9 of exhaust gas filter box 8, and the filtered fluid upper end in the exhaust gas filter box is provided with exhaust gas filter pipe 7.Breather cheek valve taps into tracheae 10, the port of export of the air-breathing filter cartridge 11 of another termination of air inlet pipe, the S-shaped crooked shape of air inlet pipe.Microphone connects loudspeaker 12 by lead 13.It is external that the oxygen filtration interface 15 of oxygen air inlet is positioned at oronasal mask.
Described microphone is the chip microphone, and its rear end is fixed on the mouth and nose cover body and is provided with wire socket 14.Described mouth and nose cover body is the hemisection garden and is peach shape, and the mouth and nose cover body as traditional is used for the mouth and nose that buckle closure is lived human body, and its limit is provided with sealing strip and is used for contacting sealing closely with human face as traditional mouth and nose cover body.Exhaust check valve and breather cheek valve are sold product by market.The port of export of exhaust check valve connects blast pipe, and the other end of blast pipe is arranged in the filtered fluid of exhaust gas filter box, and filtered fluid can be the mixed liquor of water and alcohol, or is other bactericidal liquid, is used to kill the virus that human body is breathed out, and makes harmless emission.Breather cheek valve taps into tracheae, the port of export of the air-breathing filter cartridge of another termination of air inlet pipe, and the S-shaped crooked shape of air inlet pipe, the effect of the crooked shape air inlet pipe of S shape is to be beneficial to bonding dust in air of tube wall and deposit air.Air-breathing filter cartridge, oxygen filter in interface and the exhaust gas filter pipe and are provided with kill the virus guard and dust proof and gas defence material, are conventional art, so be not repeated.
During use, it covers the mouth and nose of human body as fixed band 17 hitch of traditional oronasal mask body and function on it.Air-breathing filter cartridge and exhaust gas filter box and loudspeaker and circuit battery box are fixed on the human body waist with belt.When human body was exhaled, breather cheek valve was closed, and expiratory one-way valve is opened, and expiration in-line arrangement tracheae enters the exhaust gas filter pipe that is provided with along the filtered fluid upper end again after the kill virus in the interior filtered fluid of exhaust gas filter box and further stops the virus back to be arranged from the exhaust gas filter box.When human body was air-breathing, expiratory one-way valve was closed, and breather cheek valve is opened, and air sucks for the people in the inlet port mask body after the bonding dust in air of the crooked shape air inlet pipe tube wall of S shape through air-breathing filter cartridge disinfection filtering earlier again.
If patient needs oxygen uptake, then take off the buckle closure on the oxygen filtration interface, oxygen is introduced oxygen filtration interface with conduit get final product oxygen supply.During the human body conversation, get final product from wire socket connection microphone and loudspeaker with lead.
In a word, the utility model is anti-virus, dustproof, protection from fumes and gas defence effectively, also has the function that makes things convenient for oxygen uptake and conversation.And it is little, simple in structure also to have volume, not fragile, and cost is low and easy to use, can use in the various dangerous operations field, can promote the use of.
