Disposable Highly-Protective Oral-Nasal Mask

Abstract

A disposable highly-protective oral-nasal mask comprises a fixing part. A notch is formed in the portion, corresponding to an oral cavity, of the fixing part. An oral cavity coverage part is arranged at the notch, corresponding to the oral cavity, of the fixing part, and is detachably connected to the fixing part. A first fold part with upward external folds is further arranged on the oral cavity coverage part. A second fold part with downward external folds is arranged on a nasal cavity coverage part. Two easily deformed components are located in accommodating cavities which are formed in the fixing part in one-to-one correspondence with the easily deformed components. Both accommodating cavities are arranged in the length direction of the fixing part. One accommodating cavity is located between the oral cavity coverage part and the nasal cavity coverage part, and the other accommodating cavity is located above the nasal cavity coverage part. As a result, air circulation parts of the oral cavity and a nasal cavity are separated to reduce the air circulation between the oral cavity and the nasal cavity.

What is claimed is: 
     
         1 . A disposable highly-protective oral-nasal mask, comprising:
 a fixing part having a first notch is formed corresponding to an oral cavity;   an oral cavity coverage part, arranged at the first notch of the fixing part and detachably connected to the fixing part, wherein a first fold part with upward external folds is further arranged on the oral cavity coverage part;   a nasal cavity coverage part, on which a second fold part with downward external folds is arranged;   two easily deformed components, located in accommodating cavities which are formed in the fixing part in one-to-one correspondence with the easily deformed components, wherein both accommodating cavities are arranged in the length direction of the fixing part, wherein one accommodating cavity is located between the oral cavity coverage part and the nasal cavity coverage part, and the other accommodating cavity is located above the nasal cavity coverage part;   earloop parts, fixed to the two sides of the fixing part.   
     
     
         2 . The disposable highly-protective oral-nasal mask according to  claim 1 , wherein a second notch corresponding to a nasal cavity is further formed in the fixing part; the nasal cavity coverage part is arranged at the second notch and is detachably connected to the fixing part. 
     
     
         3 . The disposable highly-protective oral-nasal mask according to  claim 1 , wherein both the oral cavity coverage part and the nasal cavity coverage part are detachably connected to the fixing part through non-woven double-sided adhesive tapes. 
     
     
         4 . The disposable highly-protective oral-nasal mask according to  claim 2 , wherein both the oral cavity coverage part and the nasal cavity coverage part are detachably connected to the fixing part through non-woven double-sided adhesive tapes. 
     
     
         5 . The disposable highly-protective oral-nasal mask according to  claim 1 , wherein the easily deformed components are aluminum plastic strips. 
     
     
         6 . The disposable highly-protective oral-nasal mask according to  claim 1 , wherein the easily deformed components are aluminum plastic strips or deformable plastic rubber strips; non-woven double-sided adhesive tapes are further arranged on the side surfaces, close to a human body, of the aluminum plastic strips or the deformable plastic rubber strips. 
     
     
         7 . The disposable highly-protective oral-nasal mask according to  claim 1 , wherein the earloop parts are made of elastic pieces and hydrophilic non-woven fabrics which coat outside the earloop parts. 
     
     
         8 . The disposable highly-protective oral-nasal mask according to  claim 1 , wherein a protrusion part which protrudes from one side of the mask to one side of a face is arranged on the inner surface of the fixing part between the oral cavity coverage part and the nasal cavity coverage part; the protrusion part is used for preventing air circulation of the oral cavity and the nasal cavity. 
     
     
         9 . The disposable highly-protective oral-nasal mask according to  claim 1 , wherein the fixing part, the oral cavity coverage part and the nasal cavity coverage part all adopt multilayer structures which meet the requirements of disposable surgical masks.
