Background
In some medical treatment activities for serious infectious diseases, especially respiratory infectious diseases, medical staff often need to wear protective clothing for a long time and wear protective transparent face screens, goggles and masks. Medical personnel with poor vision also need to consider how to wear shape-preserving glasses. The wearing procedure is complicated, and the water mist can be formed on the goggles and the transparent face screen after the goggles and the transparent face screen are worn, so that the sight of medical personnel is greatly influenced, and great difficulty is caused to medical work. The sealed mask brings suffocation and oppression to medical staff, even nausea and vomiting, and the face is easy to be hurt and blisters, rashes and the like are generated. In addition, the medical mask used at present mainly adsorbs viruses through static electricity, and after the medical mask is used for a period of time, the static electricity of the mask adsorption material can be reduced by moisture exhaled by a wearer, so that the adsorption capacity of the mask adsorption material can also be reduced. The existing foreign air supply type protective equipment well solves some problems, but is expensive in price, heavy in equipment and limited in import to China. The price of some products newly marketed in China is reduced, but the products are still heavy and difficult to widely popularize and use. The utility model provides a medical protective face mask of air supply formula solves above problem.
Disclosure of Invention
In view of this, the utility model aims at providing a light protective face mask with air supply function, when protecting medical staff not to be infected, solve owing to wear transparent face screen, goggles and gauze mask, and the agglutination steam that causes influences sight, feel oppressive, suffocates the feeling scheduling problem, and the uncomfortable that help medical staff solved above-mentioned problem and caused feels to carry out medical work smoothly.
In order to achieve the above purpose, the technical scheme of the utility model is realized like this:
a wind-supplying medical protective mask comprises a mask body, a gas outlet valve, a silica gel partition board, a mask inner air inlet valve, orthopedic glasses, a transparent face screen, a camera support, a wind supplying device, a fan, a lithium battery, a switch, a charging socket, a filter cover, a soft silica gel sealing ring and an elastic cord. The air supply device sends filtered air into a sealed cavity formed by the transparent face screen, the cover body, the soft silica gel sealing ring and the face of the wearer, and a breathing space with micro-positive pressure is formed.
The cover body is an oval frame, and a camera support is arranged above the frame and can be used for fixing a camera. Be provided with air inlet and air outlet valve respectively in the top and the bottom of frame, preceding, rear portion respectively with transparent face screen and soft silica gel sealing washer sealing connection, adjustable length's elastic cord is installed in the rear portion four corners, can select the model according to everyone's face type, adjusts elastic cord length to soft silica gel sealing washer can closely laminate with the person of wearing face.
The silica gel baffle is divided into eye district and oronasal part district two parts with transparent face guard, and fixed orthopedic glasses with the sucking disc on the transparent face screen in eye district, the external environment of being convenient for the person of wearing clearly observes, is provided with cover internal air admission valve and air outlet valve in oronasal part district, for the person of wearing breathing region. The air supply device is packaged with a fan, a lithium battery, a switch and a charging socket, the air inlet of the air supply device is hermetically provided with a filter cover capable of filtering viruses, bacteria and PM 2.5, and the air outlet and the air inlet of the air supply device are respectively and hermetically connected with the cover body and the filter cover. The filtered air is firstly sent into the eye region, then passes through the inlet nose region of the air inlet valve in the cover, and the waste gas is discharged through the air outlet valve. The air outlet valve is generally a one-way valve, and a filter element can be added according to requirements.
Compared with the prior art, the air supply type medical protective mask has the following advantages:
(1) protective face mask realize the integration of face protection, need not to wear transparent face screen, goggles, orthopedic glasses and gauze mask respectively. Simple structure, low cost, portability and is favorable for carrying. The main body part does not need to be stored excessively at ordinary times, and can be temporarily refitted when epidemic situations exist.
(2) Protective face mask send into the safe fresh air after filtering through the fan, prevent viral infection, alleviate the oppression sense of the person of wearing, effectually prevent because airtight environment causes the blister of face, exanthema scheduling problem. The filter cover can select corresponding protective materials according to the requirement of the protection grade. Like this time the health care workers in the new corona virus epidemic ward area, need to use protective materials above kn95 for virus filtration.
(3) Protective face mask realized admitting air, giving vent to anger and used two different ways, divide into eye district and oronasal part district with the face mask, avoided the eye-shade to play this problem of water smoke interference sight.
(4) The protective mask of the utility model is easy to unpick and wash, convenient to disinfect, reusable and resource-saving. The design of the lithium storage battery is adopted, so that the service life is long.
