Abstract
A novel shielding respirator comprises a shield made of plastics or other hard materials, with the shape similarly as a half-round and the arc edge basically fitting close with the natural human face curve. A soft airproof layer is arranged around the edge of the shield, including soft breathing layers on the parts corresponding to the cheeks; the upper part of the shield is a support for the nose bridge and the lower part is a support for the mandible; both sides of the shield are provided with connecting buckles of fixing belts. An L-shaped buckle for the mandible is provided right under the mandible support. With the hard shield adopted, the shielding respirator can directly prevent pathogen from entering the respiratory tract from the face; a half-round ease space formed at the mouth and nose part helps to make the air entering from both sides more moderate so that the breathing layer can play a better role in shielding. The shield which fits close with the natural human face curve solves the malpractice problem of the traditional respirator with gaps left on both sides of the nose bridge, ensuring better shielding effect. As the breathing layers can be freely replaced and the shield can be disinfected easily, the shielding respirator is applicable for the industrial staff in disease prevention, nursing and treating, environmental protection, etc.
Description
Technical field the utility model belongs to a kind of medical protective mask, and is especially a kind of at the infectious disease special protection mouth mask by respiratory infectious such as SARS.
Background technology is current, and " atypical pneumonia " spreads especially at home in the whole world, and the people's life security in serious crisis, particularly gives treatment to SARS patient's medical personnel.The spittle that carries pathogen for prevention is by respiratory infectious, and mouth mask becomes the alternative that people stand in the breach as the first line of defence.Yet, traditional stratiform cotton cloth respirator but exists following deficiency: when 1. wearing, because the upwards supporting role of the bridge of the nose forms the space above wing of nose both sides, make outside bacterium, pathogen enter respiratory tract, cause transmission of disease by this space per os, nose.2. if the number of plies is few, do not have the effect of protection, in air-breathing process, may directly suck pathogen from the front; If the number of plies blocked up (more than 16 layers), gas permeability is poor, and mouth mask is easily moist, breed bacteria.3. be not easy to sterilization in time and cleaning, carry also inconvenient.
The summary of the invention the purpose of this utility model is to provide a kind of protection tight, can effectively intercept pathogen is invaded human body by respiratory tract novel protective mask.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of novel protective mask is characterized in that it comprises the hard protection cover that a likeness in form semicircle shape and edge camber line and human body face physiological curve coincide substantially; The edge of protective cover is provided with soft sealant, and the position corresponding with cheek, its both sides is soft breathing layer; The upper end of protective cover is the bridge of the nose bone strong point, and the lower end is the ramus of mandible support point; The protective cover both sides are provided with the junction button of fixed band.
For further strengthening the seal degree of lower jaw part, also be provided with the L shaped button of a lower jaw under the described ramus of mandible support point.
For ease of dismounting and change, described soft breathing layer can adopt thread gluing to be connected with the sealant at protective cover edge.
The novel protective mask that the utility model provides, owing to adopted the hard protection cover, can directly isolate pathogen from the front and enter respiratory tract, meanwhile form a semicircle shape and alleviate the space at snout, make the gas by the both sides turnover more be tending towards relaxing, filtration, the barrier action of breathing layer are more obvious.Protective cover and human body face physiological curve are identical substantially, have solved the drawback that the space is left in traditional mouth mask wing of nose both sides, protect tighter relatively.Bilateral is breathed layer and can arbitrarily be changed, and the protective cover sterilization is convenient.Characteristics such as in addition, it also has simple in structure, good looking appearance, use is comfortable, the scope of application is wide.Be applicable to that tradesmans such as prevention from suffering from the diseases, medical care treatment, environmental sanitation use.
Description of drawings Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the user mode schematic diagram of this novel protective mask.
Among the figure: the 1-bridge of the nose bone strong point; 2-moulds the system protective cover; The soft sealant of 3-; 4-fixed band junction button; The soft breathing layer in 5-both sides; The L shaped button of 6-lower jaw; 7-ramus of mandible support point.
As shown in Figure 1, 2, the novel protective mask that the utility model provides, it comprises the protective cover 2 that a likeness in form semicircle shape and edge camber line and human body face physiological curve coincide substantially, protective cover 2 is made by slightly flexible plastics or other hard material; The edge of protective cover 2 is provided with soft material sealant 3, the position corresponding with cheek, its both sides is soft breathing layer 5, the soft breathing in both sides layer 5 can adopt easy-to-dismount thread gluing to be connected with the sealant 3 at protective cover 2 edges, and breathing layers 5 can be by medical absorbent cotton or the making of other soft material; The upper end of protective cover 2 is the bridge of the nose bone strong point 1, and the lower end is a ramus of mandible support point 7, is provided with the L shaped button 6 of lower jaw under the ramus of mandible support point 7; The protective cover both sides are provided with the junction button 4 of fixed band, and fixed band can adopt elastic cord, also can be connected to both sides tying-up or thread gluing and connect.But L shaped 6 single injection-moldeds of buckleing of protective cover 2 and lower jaw wherein.
This novel protective mask can be processed into large, medium and small model, uses with the crowd who adapts to all ages and classes level.
