A surgical mask gripper covering nose apex, ala and mouth of a person is disclosed. Gripper is designed to enhance the flow of air through the mask filter and restrict the flow of air leaking through the periphery of the surgical face mask. Gripper covering the contours of nose apex and ala creates a tight seal between face skin and surgical mask. Low profile of gripper around nose allows a person to wear safety or eye glasses without any interference. Tight seal forces inhaled and exhaled air through the surgical mask filter thereby improving the particulate filtering efficiency and eliminate the fogging of safety glasses.

The present disclosure provides generally for a particle guard system and apparatus. The system may comprise temples, shield, and nose bridge. A particle guard may prevent or limit aspiration from entering the user's external environment via shield that covers the nose and mouth. The particle guard may comprise interchangeable components for personalization and various utility. The temples and the nose bridge may be available in various colors and styles for customization of the particle guard. The particle guard may possess attachments for various utility. Temples may comprise integrated attachments. For example, temples may contain a wireless signal device for external communication. The particle guard may comprise a sanitation system. Where the system includes external covering, shield may interface with the external covering via opening in the external covering.

Face masks configured to fit over a nose and a mouth of a user wearing an eyewear article. The face masks include a cover and an eyewear coupler. The cover is configured to the cover the nose and the mouth of the user. The eyewear coupler is attached to the cover and configured to selectively attach to the eyewear article to couple the cover to the eyewear article. In some examples, the face mask includes the eyewear article to define a face-and-eye-mask.

A faceblank (5) for a respiratory protective device or face mask hygiene product (1), where the shape of the faceblank (5) defines a number of filter openings (2, 3, 4) and which further comprises a head harness (6) or fastening for a head harness (6) and is characterised in that the filter openings (2, 3, 4) have been implemented to comprise a tongue (7), most advantageously so that the edge of each opening (2, 3, 4) is composed of a tongue. The faceblank is used with a number of replaceable filters (10) adapted in the filter openings (2, 3, 4) of the faceblank (5), each filter (10) comprising a filter part (11) and a frame (12) that encircles the filter part (11), in which frame (12) the outer edge has been implemented to comprise a groove (13)—most advantageously so that the outer edge of each frame (12) consists of a groove (13)—so that the filters (10) are fastenable to the filter openings (2, 3, 4) of the faceblank (5) by means of a tongue-and-groove connection, in which case the tongue (7) and groove (13) form an air-tight tongue-and-groove connection. Further independent claims directed to filters and methods for the manufacture of reinforced textile part, nonwoven fabric part or their combination part.

The present invention relates to a personal respiratory protection device, in particular, such a device comprising a respirator body having a periphery, a filter media, forming at least part of the respirator body, and a gasket, the gasket being located at the periphery and extending along at least a portion of its length.

A protective face mask may comprise an outer housing including a first plurality of ventilation holes, and an inner housing detachably coupled to the outer housing, the inner housing configured to cover a nose and a mouth of a user, the inner housing including a second plurality of ventilation holes. The protective face mask may also include a replaceable filter configured to be received in a space between the inner housing and the outer housing. In some embodiments, the protective face mask includes a sensor unit coupled to at least one of the inner housing and the outer housing, the sensor unit configured to detect a presence of a contaminant on the replaceable filter.

A mask according to an embodiment of the present disclosure includes: a filtering structure configured to perform an air filtering function; a buckle portion coupled to the filtering structure; and a strap connected to the buckle portion and worn on a body of a user, wherein the buckle portion includes: a body coupled to the filtering structure and having openings formed on both sides thereof; and a fixing piece having one side hinged to a sidewall of the opening and gripping the strap, wherein the strap is inserted between a side surface of the fixing piece and a side-wall of the opening to surround at least a part of an outer surface of the fixing piece, and slidably moves in one direction or both directions in the buckle portion selectively according to a shape of surrounding the fixing piece.

A unitary thermoformed protective face shield includes a curved top member adapted to conform to a user's forehead. The curved top member includes a plurality of exhaust channels formed therein for allowing ventilation. The face shield further includes a visor portion extending outward from a lower end of the curved top member, thereby creating a space between the user's face and a face cover portion. The face cover portion extends downward from the visor portion and covers and provides protection for the face of a user. A side shield portion extends inwardly from the face cover portion for shielding the sides of a user's face. Further, a perimeter flange may extend perpendicular to the perimeter of the face shield for providing structural support to the face shield.

A process of forming a fiber comprised of a plurality of bio-char particles, comprising: combining a portion of a polymer with a hemp derivative, said hemp derivative selected form a hemp carbon made by pyrolyzing a quantity of hemp stalk at between 1100-1500° C. to create a char; adding the char to a milling vessel and milling the char for a period of between 1 to 16 hours, and a full spectrum hemp extract, or combinations thereof, wherein the polymer and hemp derivative are extruded to form a fiber.

A soft medical silicone edged cushion may significantly reduce air leakage and provide comfort to a wearer of a face mask, for example, when the face mask is continually worn by a healthcare worker for a twelve hour shift of medical duty. The cushion may preferably be U-shaped and comprise a cross-section for holding an extra soft silicone gel or air, yet be sufficiently hard and elastic and of predetermined circumference to be adaptable to self-installation to the lateral edges of a face mask and coatable to protect from the escape of air and fit comfortably on a face despite the use of elastic straps with the face mask or the presence of solid plastic lateral edges of an oxygen mask or a ventilator mask. The cushion may be used to cushion a solid plastic laterally edged oxygen or ventilator mask against the use of elastic ties to tie the face mask around a patient's head. The face mask may comprise a UVC source of ultraviolet light controlled by buttons/displays/battery/USB port on the cushion or on a cartridge replacing a filter of an N95 mask.
