Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of health products, in particular to a sphygmic pressure sore prevention mask and a use method thereof. BACKGROUND

[0002] The mask is a health and epidemic prevention product, which is generally worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, droplets, viruses and other substances, and is made of gauze or paper and the like.

[0003] Among the many functions of the mask, the side leakage prevention design is an important technical point to be considered; the side leakage prevention design is to prevent air from being inhaled through the gap between the mask and the human face without being filtered. Air, like water flow, flows to where the resistance is small first. When the shape of the mask does not fit the face tightly, dangerous substances in the air will leak directly into the gap, leading to the respiratory tract of the person. Even if the filter material of the mask is good, it cannot guarantee health.

[0004] However, when wearing the mask, the mask will move with breathing or movement, thereby failing to better fit the face; at the same time, when there is a wound on the face, the edge of the mask will cause pressure on the wound when wearing the mask, leading to slow healing of the wound, and the surface of the mask is easy to adhere to the wound, increasing the discomfort when wearing the mask and reducing the protection effect of the mask.

[0005] Therefore, it is necessary to improve the prior art to solve the above problems. SUMMARY

[0022] S4, when it is necessary to release the gas, extrude the air bag, at this time the second valve opens to discharge the gas in the air bag through the one-way exhaust valve, after stopping extrusion, the second valve closes, the edge area of the mask shrinks, and it is convenient for the wearer to take off the mask.

[0023] The present application solves the defects in the background art, and has the following advantages: (1) The present application provides a mask for preventing pressure sores and a method for using the same. The air bag part is added to the edge of the mask. The tightness of the mask is adjusted by inflating or releasing the gas. The problem that the mask moves with breathing or movement in the prior art is solved, and the position of the mask is stable. This design can adapt to different face shapes and sizes, and provide personalized fit. It can also reduce the friction and pressure of the mask on the skin, and reduce discomfort and red marks.

[0024] (2) The present application adjusts the tightness of the mask by controlling the inflation state of the air bag part. When the air bag is inflated, it will expand the edge of the mask, making the mask better fit the face and reducing the gap to prevent air leakage. When the air bag releases the gas, it will return to its original state, making it convenient for the wearer to take off the mask.

The sliding strips are in an arch structure, which maintains a stable arch structure by controlling the arch foot to bear and disperse the force from the curved surface, and does not cause pressure marks on the face. The comfort and protection of the mask when worn are ensured.

[0026] (4) The present application opens the first valve when inflating the air bag, and inflates the air bag through the one-way air inlet valve. After the inflation is completed, the first valve automatically closes. The one-way air inlet valve ensures that air can only enter the extrusion bag from the outside, preventing air pollution inside the mask. The first valve prevents the extrusion bag from overexpanding, avoiding excessive pressure of the mask on the face.

[0027] The present application opens the second valve when extruding the air bag to discharge the gas, and discharges the gas through the one-way exhaust valve. After the discharge is completed, the second valve also automatically closes. The one-way exhaust valve ensures that the exhaust gas inside the mask can be smoothly discharged, maintaining the ventilation performance of the mask. The second valve prevents backflow of the exhaust gas, avoiding the exhaust gas reentering the mask, and improving the filtering effect of the mask.

[0028] (5) The sliding block is in sliding connection with the sliding groove, the position of the arch foot can be conveniently adjusted, different face shapes are adapted, and the comfort of wearing is improved; meanwhile, the matching of the arc-shaped structure and the arc-shaped groove can increase the friction between the sliding block and the sliding groove, the sliding block is prevented from being accidentally separated from the sliding groove, and the stability of wearing is improved.

[0029] (6) The mask is combined with the air bag and the wound protection function, the overall stability of the mask is increased, the mask is better fitted to the face, the possibility of gaps and air leakage is reduced; through the expansion and contraction of the extrusion bag, better breathing resistance control can be realized, the comfort and air permeability of the mask are improved; meanwhile, the arch-shaped structure can disperse pressure, local compression to the face wound is avoided, fatigue and pain are reduced, the mask is more flexible and adaptable, the comfort and safety of the wearer are improved.
