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.

DESCRIPTION OF THE EMBODIMENTS

[0027] The invention now will be described more fully hereinafter with reference to the accompanying drawings, in which illustrative embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0028] The specific implementation mode of the disclosure will now be described in detail with reference to the accompanying drawings FIGS. 1 to 2.

Embodiment 1

[0029] The disposable highly-protective oral-nasal mask provided by the disclosure comprises:

[0030] a fixing part 1, wherein a first notch is formed in the portion, corresponding to an oral cavity, of the fixing part 1;

[0031] an oral cavity coverage part 2, arranged at the first notch of the fixing part 1 and detachably connected to the fixing part 1, wherein a first fold part 3 with upward external folds is further arranged on the oral cavity coverage part 2;

[0032] a nasal cavity coverage part 4, on which a second fold part 5 with downward external folds are arranged;

[0033] two easily deformed components 6, located in accommodating cavities which are formed in the fixing part 1 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 2 and the nasal cavity coverage part 4, and the other accommodating cavity is located above the nasal cavity coverage part 4;

[0034] earloop part 7, fixed to the two sides of the fixing part 1.

[0035] The oral cavity coverage part 2 in the present embodiment may be separated from the fixing part 1 as required, and may fit again to facilitate the use on an occasion where the mouth need to open; and meanwhile, the risk of inhaling bacteria can be reduced because of the protection effect of a nasal mask.

[0036] With regard to reducing the air circulation between the nasal cavity and the oral cavity, according to the present embodiment, independent spaces are respectively formed at the nasal cavity and the oral cavity through the limitation to the direction of the folds of the first fold part 3 and the second fold part 5 arranged on the oral cavity coverage part 2 and the nasal cavity coverage part 4, internal folds of the oral cavity coverage part 2 are downward, and internal folds of the nasal cavity coverage part 4 are upward, so direct circulation of the airflow of the nasal cavity and the oral cavity is limited by adopting two reverse folds;

[0037] on this basis, the present embodiment further improves the blocking effect on the airflow between the nasal cavity and the oral cavity by additionally arranging the easily deformed components 6 between the oral cavity and the nasal cavity and better fitting the easily deformed components 6 and the face.

Embodiment 2

[0038] On the basis of the embodiment 1, a second notch corresponding to the nasal cavity is further formed in the fixing part 1 of the present example; the nasal cavity coverage part 4 is arranged at the second notch and is detachably connected to the fixing part 1.

[0039] The nasal cavity coverage part 4 and the oral cavity coverage part 2 in the present embodiment are detachably connected by the same method, which meets the use in examinations of the nasal cavities or other situations in which the nasal cavities need to be exposed without exposing the oral cavities.

[0040] In the present embodiment, both the oral cavity coverage part 2 and the nasal cavity coverage part 4 are detachably connected to the fixing part 1 through non-woven double-sided adhesive tapes;

[0041] the earloop parts 7 are made by externally coating elastic rubber bands or elastic ropes with hydrophilic non-woven fabrics.

[0042] The easily deformed components 6 are aluminum plastic strips or aluminum plastic pieces.

Embodiment 3

[0043] In order to further reduce the air circulation of the oral cavity and the nasal cavity, on the basis of the above embodiments, the easily deformed components 6 of the present embodiment are aluminum plastic strips or deformable plastic rubber strips. The non-woven double-sided adhesive tapes are further arranged on the side surfaces, close to a human body, of the aluminum plastic strips or deformable plastic rubber strips. The purpose is to make the aluminum plastic strips or the deformable plastic rubber strips fit the face better.

Embodiment 4

[0044] In order to better reduce the air circulation of the oral cavity and the nasal cavity, a protrusion part which protrudes from one side of the mask to one side of the face can also be arranged on the inner surface of the fixing part between the oral cavity coverage part 2 and the nasal cavity coverage part 4. The protrusion part is used for preventing the air circulation of the oral cavity and the nasal cavity. It should be noted that the arrangement of the protrusion part is only to increase obstruction of the air circulation between the nasal cavity and the oral cavity, but may not affect the breathing of the oral cavity and the nasal cavity. In order to avoid the displacement of the protrusion part in a process of talking or opening the mouth, a bonding layer, such as a non-woven double-sided adhesive tape, can be arranged on the side, in contact with the face, of the protrusion part.

[0045] The fixing part 1, the oral cavity coverage part 2 and the nasal cavity coverage part 4 in each of the above embodiments all adopt multilayer structures which meet the requirements of disposable surgical medical masks.

[0046] Therefore, the research and development of the disposable highly-protective oral-nasal mask of the disclosure can not only effectively block a virus spreading problem between people, but also prevent an individual from re-inhaling pathogenic bacteria coughed out from his oral cavity into the nasal cavity again. In special places, such as restaurants and stomatological hospitals, the nasal mask can continue to perform individual protection after the oral mask is removed, which can not only meet the protection against virus infection of people, but also improve an adverse effect on an individual caused by wearing the oral mask for a long time, so the needs of normal life are met better. The novel disposable highly-protective oral-nasal mask is low in cost and wide in application range, and has a good application prospect.

[0047] Although the embodiments of the disclosure has been shown and described, for those of ordinary skill in the art, it can be understood that a number of variations, modifications, substitutions, and variants may also be made on these embodiments without departing from the principle and spirit of the disclosure, and the scope of the disclosure is limited by the attached claims and equivalents thereof.
