An intranasal cannula apparatus for use to filter air that enters a nasal cavity of a user is provided. The apparatus includes a pair of elongated bodies coupled together and designed to insert in the nasal cavity of the user. Each elongated body has a front portion, a rear portion, a top portion, a bottom portion and side portions that form an internal cavity therein. Each elongated body has a nasal opening disposed on the bottom portion of the elongated body that aligns with one of the nostrils of the user. A dorsal opening is disposed on the top portion of each elongated body. A pair of filters is disposed within the pair of elongated bodies. The apparatus is designed to permit air from the nostrils of the user to pass entirely through the nasal openings and dorsal openings in the elongated bodies to the nasal cavity of the user.

A self-adhesive nasal mask includes a main body shaped to form to and cover a contour of a nose on a face of a user, the main body including peripheral tabs, each of the peripheral tabs including a lateral self-adhesive strip on an underside facing the face of the user, the main body constructed from a material that impedes unfiltered exhales from the user.

According to some embodiments, a protective face mask to protect medical personnel by filtering exhaled air of infectious patients is disclosed. The protective face mask comprises a first layer, a second layer and a third layer. The second layer comprises a molecular sieve desiccant. The molecular sieve desiccant is between 0.1 cm and 10 cm thick.

A filter tube respirator having a filter tube and at least one breathing orifice interface. The filter tube is made of filtration material so that it is gas permeable, is substantially hollow, and has a pair of ends. The breathing orifice interface may include a nose piece, a mouth piece, and a flap piece. The filter tube has a tube breathing hole located between the ends for accepting the breathing orifice interface and has a tube valve hole opposed to the tube breathing hole for accepting a one-way valve. An attachment device selectively connects the filter tube to an individual during use.

Embodiments relate generally to a nasal dilator comprising a body for insertion into a nasal cavity of a nose. The body includes a loop structure having an inner surface, a reverse outer surface, a first side and a second side opposite to the first side. The inner surface defines an aperture and the reverse outer surface is configured for urging against a nasal passage wall of the nose. The body further includes an arm member having a first end coupled to the loop structure and a free end, the arm member extending outwardly from the loop structure and configured to extend along a nasal passage of the nasal cavity and engage with an internal surface of a nostril of the nose.

The present disclosure is related to objects, apparatuses, devices, and methods of utilizing UV-C radiation to sterilize pathogenic contamination of materials such as air and bodily tissues.

A head support device having two handles or receptacles connected by a support strap, wherein the handles or receptacles are configured to support or accommodate the user's hands, and the support strap is configured to support or accommodate a portion of the user's head, namely, the user's face. In use, the user wears or otherwise passively contacts the handles or receptacles of the device such that the support strap maintains a desired distance between the user's hands. When in the seated position, the user contacts the support strap with their face, such that the user's hands and the handles or receptacles contact opposite sides of the user's head. The user further supports their arms by placing their elbows on their knees, upper legs, or other stable surface, thereby transferring the weight of their head to a stable surface via their forearms.

A portable air filtration and disinfection device for a respirator system includes a casing, an inhalation filter assembly, and an exhalation filter assembly. The inhalation filter assembly includes an intake duct for receiving breathing air, an inhalation gas filter for filtering the breathing air, and an inhalation duct to provide the filtered breathing air. The exhalation filter assembly includes an exhalation duct for receiving exhaled air, an exhalation gas filter and an exhalation liquid filter for filtering and disinfecting the exhaled air, and an outlet duct for releasing the filtered and disinfected exhaled air.
