| 128206140 | Mask adhesively attached to face | 6 |
| 20090255535 | DROPLET COLLECTION DEVICES AND METHODS TO DETECT AND CONTROL AIRBORNE COMMUNICABLE DISEASES UTILIZING RFID - A filtering face mask that comprises: (a) a mask body; and (b) at least one diagnostic device for identifying whether the wearer of the mask is infected with a contagious disease. | 10-15-2009 |
| 20090277451 | STRAPLESS CANTILEVERED RESPIRATORY MASK SEALABLE TO A USER'S FACE AND METHOD - A facial mask for filtering ambient air is formed from a pre-form of a multilayer flexible flat filter member with solid plastic side ribs of a size to extend the filter member over the mouth and nostrils of the user. The flat pre-form filter member can have a trapezoidal perimeter with an endless band of a hypoallergenic adhesive tape encircling a perimeter opening of the filter member and operable for sealing with the user's skin to prevent leakage over extended use. Portions of the adhesive tape can self-seal to form a structural base for maintaining a central concavity by cantilevering the side ribs to ensure a large filtration area offset from the nostrils and mouth of the user. The flexible filter material can further include an activated carbon layer. | 11-12-2009 |
| 20120097167 | MASK WITH NOSAL CUSHION - Provided is a mask with a nosal cushion, the mask consisting of a filter that filters dust, wherein, the edges of the filter are folded back to create flaps that follow the depressions on both sides of the nosal region. A sponge of urethane foam or the like is affixed inside the flaps, thereby improving the fit of the mask by conforming the mask to the contours of the nosal region, resulting in a mask cushion with a nosal cushion that has cushioning properties and strong protective capabilities. | 04-26-2012 |
| 20120103339 | SURGICAL FACE MASK, INCLUDING REUSABLE MASKS, WITH FILTERED INHALATION AND EXHALATION VALVES - Face masks that can be used, for example, in medical and surgical procedures, including both completely or partially disposable and reusable masks, that can be custom fitted to the wearer, and which can include one or more filtering inhalation and exhalation valves and/or compartments allowing for separated filtering of inhalation and exhalation gases. Some embodiments include systems, methods and kits for reducing contaminants in an inhalation and exhalation flow stream. | 05-03-2012 |
| 20150013681 | Apparatus with Exhaust Spacer to Improve Filtration of Pathogens in Respiratory Emissions of Sneezes - Apparatus and method to mitigate the spread of respiratory emission of a sneeze are disclosed. The apparatus includes a spacer component and at least one filtration component. The at least one filtration component is disposed atop the spacer component. The spacer component includes a corrugated sheet, which forms a plurality of directional flutes to direct filtered air out of the apparatus. The least one filtration component filters the respiratory emission to produce the filtered air. In accordance with the method, the respiratory emission is filtered through at least one filtration component to produce filtered air, and the filtered air is directed through a spacer component comprising a corrugated sheet, which forms a plurality of directional flutes that direct the filtered air out of the apparatus. | 01-15-2015 |
| 20220134144 | FACE PROTECTION MASK - Face protection mask comprising a flexible filtering screen shaped to cover the mouth and nose of the user. The mask incorporates an adhesive element projecting from the upper edge of the filtering screen and forming a flexible appendage configured to cover—in use—a substantial portion of the nose of the user, adhering thereto. | 05-05-2022 |
