Description
Technical Field
The utility model relates to the field of medical instrument research, in particular to a mask support sheet capable of expanding an effective inhalation area.
Background
The new coronavirus is also transmitted in mutation, and an effective method for preventing infection of the new coronavirus is an important and effective preventive measure except vaccination when the mask is worn outside.
The existing medical surgical mask is one of the most commonly used masks. The medical surgical mask can prevent the carrier from spraying the spray, reduce the spray quantity and the spray speed, block the spray nuclei containing the viruses and prevent the wearer from inhaling. During the period that the new crown epidemic situation is not over, people can be required to wear the medical surgical mask in daily travel.
However, when the wearer wears the mask to exercise or to perform work requiring exertion, metabolism and vital capacity of the wearer are increased, and the demand for oxygen is increased. When a wearer of the mask inhales violently, negative pressure is generated outside the mask, the mask can be tightly attached to nostrils along the periphery of the nose, and other parts of the mask can not be ventilated because the mask is tightly attached to the face, so that the effective ventilation area of the mask is greatly reduced, the user can breathe unsmoothly, and even choking occurs; hypoxia dizziness and even lung function damage can occur for a long time.
When the medical surgical mask is worn, people feel uncomfortable caused by reciprocating inhalation of the inner layer of the mask at the mouth and the nose, and if the mask becomes moist due to the influence of gas exhaled by a user, the ventilation capacity of the mask is reduced by 10 to 20 percent; in order to keep wearing the mask to have a comfortable feeling, a certain distance is needed between the nose and the mask to keep the breathing smooth, so that the wearer often pulls the mask outwards when breathing is not produced, and even moves the mask to the lower part of the nostrils.
The prior art (grant bulletin number: CN 2618631) of the plane mask cushion attempts to solve this problem. The technology adopts a light and hard single-sided film or double-sided film paper or plastic material to manufacture a liner main body, and the liner main body is provided with a plurality of ventilation holes; the back of the liner main body is tightly attached to the mask. Although this technique can form a certain distance between the nose and the mask, the cushion body itself is airtight, even if the cushion body is provided with a plurality of ventilation holes, the ventilation area of the mask is greatly reduced, the improvement of ventilation effect is not ideal, and the technique is that the mask cushion of the utility model is simply fixed on the inner face of the mask by sandwiching the ends of the left and right side ear strips into the folds inside the mask when the mask is worn; if the left and right side ear strips do not have a certain hardness, the cushion body cannot be fixed, and if the cushion body has a certain hardness, edges on both sides of the mask cannot be well attached to the face to form gaps, and the outside air is inhaled by a user of the mask without being filtered by the mask.
The prior art (authorized publication number: CN 207948981U) increases the filtering area by crimping the filter layer, and the method can increase the filtering area of the mask, reduce the respiratory resistance and improve the air permeability, but also increase the production difficulty, increase the production cost and increase the thickness of the mask, and a user cannot ensure that the crimped filter layer cannot be extruded to overlap, and the crimped filter layer can reduce the respiratory resistance after being extruded to overlap, so that the function of improving the air permeability cannot be realized, and the respiratory resistance and the air permeability can be improved.
The existing medical surgical mask has the defect that when people beat yawns, the mask can be driven to move downwards because of the large downward movement of the chin, and even the lateral edge of the mask with the metal strip slides down to the lower part of the nose, so that the mask loses epidemic prevention effect.
