Description
Technical Field
The utility model belongs to the technical field of the gauze mask, in particular to medical plane protective facial mask.
Background
A medical plane protective mask is a protective article commonly used by medical staff. Because the contour of the nose area is changed greatly, the flat mask is difficult to realize the tight fit between the upper edge of the mask body and the periphery of the nose of a wearer, and the hydrous hot air flow exhaled by the mouth and the nose is easy to diffuse out from the gap between the upper edge of the mask body and the periphery of the nose. If the wearer is wearing glasses, the hot, aqueous air condenses on the lenses of the glasses, thereby forming a mist on the lenses of the glasses, which affects the vision of the wearer.
The prior art also provides a solution to this problem. Chinese patent document CN 209594791U discloses a mask for preventing glasses from fogging, which is provided with an adhesive strip and an exhalation tube with a one-way valve, wherein the length of the adhesive strip is flush with the upper edge of the mask, and the adhesive strip is adhered to the skin to seal the upper edge of the mask body and the periphery of the nose wing when in use. Chinese patent document CN 212014563U discloses an anti-fogging mask for glasses, which is provided with an anti-fogging body composed of a rubber body, a shaping sheet and a sponge body at the upper edge of the mask, and aims to prevent the hot air containing water exhaled from the mouth and nose from escaping from the gap between the upper edge of the mask and the periphery of the nose. Above-mentioned technical scheme can play certain glasses of preventing effect of hazing, but processing is inconvenient or the travelling comfort of use is not good enough, can not see the plane protective facial mask who uses this type of improvement scheme in the market.
Disclosure of Invention
An object of the utility model is to overcome the not enough of prior art, provide a medical plane protective facial mask, its probability that can reduce the moisture hot gas flow of mouth nose exhalation from the cover body along with the gap around the nose effuses.
In order to achieve the above purpose, the technical solution of the present invention is as follows:
medical plane protective facial mask, including the cover body and hangers, the last edge of the cover body is provided with the metal strip, the quantity of metal strip is 2, and 2 metal strip levels set up side by side, and every hanger corresponds a metal strip, and an extreme point of hanger is connected in the side of the cover body, and another extreme point of hanger is connected in the medial extremity department that corresponds the metal strip.
The invention concept created by the invention is as follows: in the prior art, the U-shaped bent metal strip is pulled off from the lateral direction of the hangers at two sides and is easy to deform, so that an overlarge gap is generated between the upper edge of the mask body and the periphery of the nose. The metal strip in the prior art is divided into two parts, when the nose wing structure is used, the two metal strips are respectively positioned on two sides of the nose wing, and the metal strips are not bent in a U shape. The part of the mask body between the two metal strips is attached to the nose by pulling the hanging lugs. On the other hand, one end point of the hanging lug is connected with the end point of the inner side of the corresponding metal strip, the end point of the inner side of the metal strip is stretched towards two sides under the pulling of the hanging lug, the end point of the outer side of the metal strip is correspondingly extruded towards the nasal alar direction, the two sides of the nasal alar can be better sealed, and therefore the probability that the hot water-containing air flow exhaled by the mouth and the nose is scattered from the gap between the upper edge of the mask body and the periphery of the nose is reduced.
As an improvement, the 2 metal strips are arranged symmetrically left and right about the upper edge of the cover body.
As an improvement, the hanging lugs are connected to the outer surface of the mask body, the inner surface of the mask body, which is in direct contact with the skin, is not affected, comfort is improved, and meanwhile, the mask body is tightened on two sides of the alar wings by the hanging lugs, so that sealing performance between the upper edge of the mask body and the periphery of the nose is improved.
As a further improvement, the outer surface of the cover body is provided with a hanger guide hole, and a hanger penetrates through the hanger guide hole. The hangers are limited by the hanger guide holes.
As a further improvement, the upper edge of the cover body is provided with an extension strip, and the extension strip is turned inwards towards the inner surface of the cover body. When the mask is used, the extension strip is plugged in the gap between the upper edge of the mask body and the periphery of the nose, so that the sealing performance between the upper edge of the mask body and the periphery of the nose can be improved.
As a further improvement, the material of the extension strip is consistent with that of the cover body. When in processing, the height of the cover body is only required to be increased, and the cover body on the metal strip can be used as an extension strip.
To sum up, the utility model discloses only carry out simple improvement to plane protective facial mask's current structure, on the basis that does not increase other materials, improved on the cover body along with the leakproofness around the nose, reduced the probability that glasses hazed.
