MASK WITH STEAM HEATING Russian patent published in 2019 - IPC A61F7/03 A61H33/12 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, specifically to versions of a mask with steam heating. In the first embodiment, the mask comprises a mask which includes a mask body part covering the nose and mouth of the wearer when wearing the mask, a pair of throws provided on the left and right ends of the mask body part. Mask comprises a steam generator on a part of the body of the mask, in which the area of the area occupied by the steam generator is equal to or greater than 30 % and is equal to or less than 80 % of the surface area of the part of the mask body on the side of the owner. Steam generator includes steam generating part. Steam generator includes the first sheet on the surface of the steam generating part on the side of the owner, as well as the second sheet on the surface of the steam generating part, which is opposite to the surface on the side of the owner. Degree of air permeability of first sheet is equal to or less than 7,000 s/100 ml. Degree of air permeability of the second sheet is more than 8,000 s/100 ml. Maximum value of absolute humidity in mask during use of mask with steam heating is equal to or greater than 12 g/m³ and is equal to or less than 50 g/m³. Second embodiment of the mask differs from the first one in that the degree of air permeability of the second sheet is equal to or greater than 250 s/100 ml and is equal to or less than 8,000 s/100 ml, and the degree of air permeability of the first sheet is equal to or less than 20 % of the degree of air permeability of the second sheet.

EFFECT: technical result is improved effect of dampening of throat mucosa and nose by inhalation of air, which is heated in mask during steam generation and has high absolute humidity inside mask.
