Technical Field
The invention relates to the field of medical apparatus and instrument research, in particular to a mask supporting sheet capable of expanding an effective air suction area.
Background
The new corona virus is also transmitted in a mutation way, and an effective method for preventing the new corona from being infected is an important and effective prevention measure for wearing the mask outside except vaccination.
The existing medical surgical mask is one of the most commonly used masks. The medical surgical mask can prevent a person who contacts the virus carrier from spraying droplets, reduce the droplet amount and the spraying speed, and can block droplet nuclei containing the virus to prevent the person who wears the medical surgical mask from inhaling. When the new crown epidemic situation is not finished, people can be required to wear the medical surgical mask in daily trips.
However, when people wear the mask to do sports or do strenuous work, the metabolism and vital capacity of people are increased, and the demand of oxygen is increased. When a wearer of the mask strongly inhales, negative pressure is generated outside the mask, the mask can be tightly attached to exhaling nostrils along the periphery of the nose, other parts of the mask cannot play a role in ventilation because of being tightly attached to the face, the effective ventilation area of the mask is greatly reduced, the breathing of the wearer is not smooth, and even suffocating and choking are caused; and the patient can suffer from anoxia, dizziness and even lung function damage after a long time.
When the medical surgical mask is worn, people can feel uncomfortable feeling caused by back and forth suction of the inner layer of the mask at the mouth and nose, and if the mask becomes damp due to the influence of air exhaled by a user, the ventilation capacity of the mask can be reduced by 10 to 20 percent; in order to keep wearing the mask comfortable, a certain distance needs to be reserved between the nose and the mask to enable breathing to be smooth, so that a user wearing the mask often lifts the mask outwards when breathing is not in birth, and even moves the mask to the lower side of the nostrils.
The prior art (grant publication No. CN 2618631) of the flat mask cushion attempts to solve this problem. The technology adopts a light and hard paper or plastic material with single-sided film coating or double-sided film coating to manufacture a liner main body, and the liner main body is provided with a plurality of air holes; the back of the pad main body is tightly attached to the mask. Although this technique can form certain distance between nose and gauze mask, the liner main part itself is ventilative, even the liner main part is provided with a plurality of bleeder vents, still makes the gauze mask area of breathing greatly reduced, and the improvement of ventilation effect is not ideal, and this technique "when wearing the gauze mask, through with the terminal centre gripping of left and right side ear strip in the fold of gauze mask inboard. If the left and right side ear strips do not have certain hardness, the pad main body cannot be fixed, and if the left and right side ear strips have certain hardness, the edges of the two sides of the mask cannot be well attached to the face, so that a gap appears, and the defect that outside air is inhaled by a mask user without being filtered by the mask exists.
The prior art (No. CN 207948981U) discloses a mask for increasing the internal filtering area, which increases the filtering area by folding a filtering layer, and although the method can increase the filtering area of the mask, reduce the breathing resistance and improve the air permeability, the method also increases the production difficulty, increases the production cost and increases the thickness of the mask, and a user cannot ensure that the folded filtering layers are not overlapped due to extrusion, and after the folded filtering layers are overlapped due to extrusion, the breathing resistance is reduced, and the function of improving the air permeability cannot be realized, and the breathing resistance and the air permeability are possibly improved.
The existing medical surgical mask has the defect that when people are yawned, the chin of the people can move downwards to a large extent to drive the mask to move downwards, and even the transverse edge of the mask with the metal strip slides to the lower part of the nose, so that the epidemic prevention effect of the mask is lost.
