Description

Technical Field

[0001] The invention relates to a closed medical mask and belongs to the technical field of masks. Background Art

[0002] A mask is a sanitary product, generally worn on the mouth and nose to filter the air entering the mouth and nose, so as to prevent harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. It is made of gauze or paper. The mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, or when working in a dusty and other polluted environment, wearing a mask is very effective. Masks can be divided into air filtering masks and air supply masks.

[0003] Air supply masks refer to the clean air source isolated from harmful substances, which is delivered to the face of people through pipes and masks for breathing through power such as air compressors and compressed gas cylinders. Air filter masks are the most widely used in daily work. The structure of an air filter mask should be divided into two parts. One is the main body of the mask, which can be simply understood as a mask frame; the other is the filter material part, including filter cotton for dust prevention and chemical filter boxes for anti-virus.

[0004] The anti-side leakage design of the mask is to prevent air from being inhaled through the gap between the mask and the human face without being filtered. Air is like water flow, it will flow to where the resistance is small. When the shape of the mask does not fit the human face tightly, dangerous substances in the air will leak in from the loose fit and enter the human respiratory tract. So, even if you choose a mask with the best filter material, it cannot guarantee the health of the user. However, most of the masks currently circulating on the market have poor tightness, especially in the nasolabial groove and mandible. When inhaling, it is obvious that unfiltered air can be directly inhaled from the nasolabial groove, face, and mandible, which will bring great hidden dangers to the safety of the user. Since the mask is worn for a long time, its wearing comfort is also required to be high, because the user will produce liquids such as sweat in the process of wearing the mask. If it is not treated in a certain way, it is easy to cause liquid accumulation, affecting the use and other problems.

[0005] The Chinese invention patent with the authorization announcement number CN208987852U discloses a cordless protective mask structure, which discloses that a soft rubber strip is bonded to the inner edge of the mask body to improve the fit between the mask and the face. However, as a medical mask, it needs to be anti-allergic, and the sweat absorption function is also particularly necessary. It must be comfortable. At the same time, the fit between the soft rubber strip and the face is limited, and the mask cannot ensure sufficient sealing. The Chinese invention patent with the authorization announcement number CN205456250U discloses a surgical mask, which discloses that a highly absorbent resin layer is provided on the inner side of the upper edge of the mask body, which can only absorb water locally, and the mask has poor sealing. The Chinese invention patent with the authorization announcement number CN202184173U discloses a sealed mask used in the nursing of infectious diseases, which discloses that a metal strip is bonded to the outer edge of the mask surface, a plastic double-sided adhesive strip is attached to the outer side of the metal strip, and a protective film is covered on the outer side of the adhesive strip; the mask needs to tear off the metal strip in an environment with high sealing requirements, which is complicated to operate, and the sealing structure is simple, and the water absorption effect is not ideal. The Chinese invention patent with authorization announcement number CN200995002Y discloses a sanitary protective mask, in which an annular sealing layer is provided at the position where the mask meets the human face. The annular sealing layer has a simple structure, cannot achieve a good sealing effect, and does not have the function of absorbing sweat. Summary of the invention

[0006] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a closed medical mask.

[0007] The technical solution adopted by the present invention is: a closed medical mask, comprising a mask body and hanging ropes symmetrically arranged on both sides of the mask body; a closed layer is arranged on the inner side of the mask body facing the face, and the closed layer is bonded to the inner edge of the mask body;

[0008] The sealing layer includes anti-allergic tape, medical absorbent cotton, and a waterproof and oil-proof layer; the waterproof and oil-proof layer is bonded between the anti-allergic tape and the medical absorbent cotton, and small holes are evenly arranged on the anti-allergic tape, and the small holes are connected to the medical absorbent cotton. The waterproof and oil-proof layer can be made of polyethylene, polypropylene, polyurethane, polylactic acid and other materials, among which polyurethane is preferably used.

[0009] Furthermore, the structure of the sealing layer is as follows: a first medical absorbent cotton and a second medical absorbent cotton are respectively arranged on both sides of the anti-allergic tape, and a waterproof and oil-proof layer is arranged between the first medical absorbent cotton located on the outside of the mask body and the anti-allergic tape, the waterproof and oil-proof layer wraps the first medical absorbent cotton, and the medical absorbent cotton on both sides of the anti-allergic tape are connected through small holes on the anti-allergic tape.

[0010] Furthermore, the area of ​​the first medical absorbent cotton of the closed layer located on the outside of the mask body is larger than the area of ​​the second medical absorbent cotton of the closed layer located on the inside of the mask body; when sweat is produced, the second medical absorbent cotton absorbs the sweat and penetrates upward through the small holes. Since the area of ​​the first medical absorbent cotton is larger, excessive accumulation of moisture at the second medical absorbent cotton in the mask body is prevented. The second medical absorbent cotton is evenly spaced and bonded to the small holes to ensure a strong fit between the tape and the face. The second medical absorbent cotton can be in the form of several blocks and evenly spaced and arranged to match the small holes.

[0011] Furthermore, the structure of the sealing layer can also be: a waterproof and oil-proof layer and a first medical absorbent cotton are sequentially arranged on the side of the anti-allergic tape close to the outer side of the mask body, and the waterproof and oil-proof layer wraps the first medical absorbent cotton; the anti-allergic tape is arranged with at least two gaps; to prevent the tape from accumulating, wrinkling, and degumming in places such as the nasolabial groove if only one anti-allergic tape is used.

[0012] Furthermore, the anti-allergic adhesive tape and the side of the medical absorbent cotton close to the cheek are located in the same plane to prevent unevenness from affecting the sealing and fitting of the anti-allergic adhesive tape.

[0013] Furthermore, the edge of the mask body is hexagonal, which fits the face shape and achieves closure at the structural level.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The main advantage of the present invention is that the mask of the present invention forms a tightly closed space between the human face and the mask, preventing unfiltered gas from directly entering the mask, significantly improving the safety of the mask, and can also absorb sweat and other liquids generated during use, so that its comfort and stability are also guaranteed. At the same time, anti-allergic tape is used to seal the edge of the mask body, making the mask more professional and reliable.

[0016] 2. The present invention adopts anti-allergic adhesive tape and medical absorbent cotton to prevent sweat from soaking the skin and prevent degumming, and can absorb more sweat. The medical absorbent cotton can also achieve a sealing effect after absorbing moisture. The presence of the waterproof and oil-proof layer prevents excessive accumulation of sweat and causes degumming, and protects the first medical absorbent cotton to prevent it from being directly exposed to the outside.
