A device for blocking the nasal airway at the opening of the nostrils has two tubes that terminate at distal tips. The tubes are each separated into channels, or lumens, running the length of the tubes, including an outer lumen that extends from an inflation connection port to an inflatable donut just below the distal tip of each tube. With the distal tips received in the respective left and right nostrils of the user, the donuts are inflated to close off the nostrils at the rim, adjacent the nasal vestibule. Filters may be provided between the inflation ports and the distal tips for cleaning air prior to entry into the nasal cavity. The device may further include left and right ear straps to secure the device on the user's ears.

A reusable face respirator mask for respiratory protection comprising a body dimensioned to fit over a portion of a face of a wearer, including a rigid support component and a flexible seal component molded to the rigid support component, a replaceable filtering element sized and configured to removably cover the rigid support component, and a cover configured to removably couple with the rigid support component of the body. The filtering element is used to filter particles and/or pathogens from inhaled and/or exhaled air. A thumb release located on the cover allows the wearer to decouple the cover to accommodate frequent replacement of the filtering element. The flexible seal component is configured to interface with the face of the wearer and deform under moderate pressure to create a substantially airtight seal with the wearer's face.

 Appl.No 2024122123 Applicant Inventor Огнерубов Дмитрий Викторович (RU)
FIELD: breathing masks or helmets. SUBSTANCE: nasal filter is intended for protection of human respiratory organs against harmful environmental factors. Nasal filter comprises one flexible U-shaped element and two rigid elongated support elements whereon elliptic filtration segments are mounted. Each filtering elliptical segment has cutouts. Cutouts of each filtering elliptical segment are arranged with exclusion of overlapping of cutouts of the previous or next filtering elliptical segment. Cutouts on the filtering elliptical segments form the direction of the air flow entering the nasal canal, along the spiral path. Flexible U-element is configured to be integrated into the nasal canal. Flexible U-shaped element further comprises at least one solid filter element arranged between filtering elliptical segments. Cutouts of each filtering elliptical segment are located on diametrically opposite sides of each filtering elliptical segment. EFFECT: more effective protection of the nasal cavity from negative environmental factors. 3 cl, 3 dwg
