The utility model can be used to prevent invasion of microbe and harmful dust effectively, is applied to the prevention of cross-infecting of contagion, is comfortable to wear, has good air permeability, can be repeatedly sterilized and reused, in particular to being adapted for protection of professional prevention staffs.
Description
(1) technical field
The utility model relates to the mouth mask that a kind of professional preventing microorganism is used, and belongs to the protective articles technical field.
(2) background technology
At present, along with the fast development of industry, bring certain influence for the purification of air, again because of the mankind's intensive and frequent economic activity, chance is provided for transmission of disease and cross-infection,, makes many infectious diseases that more communication space be arranged because people's prevention consciousness is thin.Especially once brought serious disaster to the mankind through the infectious disease of respiratory infectious, the popular global death toll that once made of influenza surpasses 2,000 ten thousand for the first time; Pulmonary tuberculosis was also once walked crosswise the whole world, was still the serious challenge that the whole world must be faced until today; It is wide that current precipitate SARS (severe acuterespiratory syndrome) is that SARS is involved scope, and the condition of a disaster is heavy, and the fear that causes has therefrom involved the whole world.Isolate in this state and protect Susceptible population to seem very important, the protection that wears masks is people's common methods, also is one of means that prevent cross-infection.Existing mouth mask roughly has three classes: 1, medical mask, and there are papery or gauze material to constitute, its major function is the bigger particulate (about 10um) of blocking-up particle, especially has little effect every virus every bacterium; 2, active carbon mask adds absorbent charcoal material in the mouth mask bed of material, main effect is every flavor, and effective preventing microorganism; 3, anti-dust respirator mainly is dustproof, has little effect every bacterium.So far, still do not have the mouth mask of effective preventing microorganism (bacterium, virus, Chlamydia, mycoplasma etc.), and the design of existing mouth mask shape and structure is unreasonable, does not possess the condition of preventing microorganism.
(3) summary of the invention
The utility model is for remedying the deficiencies in the prior art, and provides a kind of and can effectively isolate the invasion and attack of microorganism and harmful dust, keeps off infection and cross-infection preferably, and rational in infrastructure, use comfortable tailored version preventing microorganism mouth mask.
The utility model is finished by following technical measures.
The utility model mainly is made up of capsula interna, shell and filter, and wherein, the base of shell connects capsula interna, and filter is arranged on the shell.
Three filters are set on the shell.
Setting fastening is arranged on the shell.
Capsula interna is complementary with the base of shell ringwise.
Filter is made up of protective cap, base, filter paper and fibrous filter membrane, and protective cap is connected with base by screw thread, and base is fixed on the shell, places filter paper and fibrous filter membrane between protective cap and base.
Between protective cap and base, place and to place sieve plate, filter paper and fibrous filter membrane.
Described filter paper is common filter paper.
Described fibrous filter membrane is that the aperture is the polycarbonate filter membrane of 0.2um.
Protective cap and base are equipped with through hole.
On the described sieve plate passage is arranged.
Capsula interna is manufactured by medical grade rubber.
Shell in the utility model is a convex shape, and according to the design of human face's physiological structure characteristics, breathing space is big, cooperates with capsula interna, guarantees that mouth mask and face are airtight fully, and has supporting role; Three filters are set on shell, can guarantee abundant breath, reduce aeration resistance; Filter adopts screw connection structure, is convenient to change filter paper and fibrous filter membrane.Using fibrous filter membrane, purpose is preventing microorganism effectively, and filtration sterilization is the principle with the physics detention, removes the microorganism in gas or the liquid, and this technology has been used to many aspects in the field of sterilizing, as the purification degerming of cell and biology and air etc.; Use common filter paper, have further filtered air and filter membrane is had protective effect; Sieve plate not only has protection filter paper and filter membrane effect, and can make them tightr, guarantees the preventing microorganism effect.Use the utility model can effectively pre-preventing microorganism and harmful dust invasion and attack, be applicable to infectious disease and the prevention of cross-infection, and have comfortable wearing, good permeability and the use of can sterilizing repeatedly, be specially adapted to professional's protection.
