US 12,702,872 B2 · Annular unit for moisture management in respiratory mask

Abstract

Examples of the present disclosure relate generally to absorbing elements in respiratory face masks. In some examples, a structure for respiratory masks that can both absorb moisture from the face (such as perspiration, as well as from condensed moisture in the breath), and maintain a low breath resistance (won't increase the breath resistance significantly) is disclosed herein. The structure includes an annular structure added to the respiratory masks for moisture management. In some examples, the annular structure is made up of moisture absorbent materials. This structure may also be known as an absorbing element operable to absorb moisture effectively, provide a respiratory mask with improved moisture control characteristics, reduce fogging of a face shield or eyeglasses of the wearer, and reduce the amount of uncomfortable moisture buildup on the face of the wearer.

Dependent claims

An absorbing element for a face mask, the absorbing element comprising:

a facing layer operable to allow moisture to penetrate into the absorbing element;
a plurality of absorbing sheet layers comprising a first absorbing sheet layer and a second absorbing sheet layer operable to disperse the moisture within the absorbing element;
an absorbent core operable to absorb the moisture and positioned between the first absorbing sheet layer and the second absorbing sheet layer, wherein the first absorbing sheet layer and the second absorbing sheet layer comprise a same material;
a back layer operable to contain the moisture within the absorbing element;
and
a plurality of flaps configured to extend at sides of the face mask,
wherein the absorbing element is removably attached to an inner surface of the face mask via an attachment element, and wherein the absorbing element is adapted to be removed and replaced by a second absorbing element.
