Devices and methods of inhibiting the inhalation of particulates using a resiliently deformable filter packaged in a sealed envelope containing a liquid medium. The method includes opening the sealed package to thereby expose the filter to ambient air; removing the filter from the package; inserting the filter into a distal region of a nostril; and urging the filter from the distal region to a proximal region of the nostril while simultaneously swabbing the distal region with the liquid disinfectant. The filter includes: an initial stage characterized by a first pore size; an intermediate stage characterized by a second pore size; and a final stage characterized by a third pore size, wherein the third pore size is a smaller than the first and second pore sizes.

A nasal insert may include a wall in the shape of a tube, the wall including a first end defining a first orifice and a second end defining a second orifice. The first end may have a diameter, diagonal measurement, or cross-sectional area larger than that of the second end. The first end may define at least one break in the wall, so that the first end incompletely encircles the first orifice. The second end may completely encircle the second orifice.

Nasal cannula assemblies for providing respiratory therapy to patients are provided. A nasal cannula assembly can include a cannula, an optional manifold which may be removable, a gas supply tube, and a securement mechanism. Securement mechanisms can include headgear straps, cheek pads, or an adhesive nose strip. A nasal cannula assembly can also include a lanyard, lanyard clip, and/or lanyard connector to help support the weight of a main gas delivery conduit.

An atomizer comprises an atomizing body, an atomizing base disposed at one end of the atomizing body, and a fixing member installed outside the atomizing base and connected with the atomizing body. The atomizing base is fixed on the atomizing body by the fixing member, and the fixing member is made of a material that can be adsorbed by a magnet and comprises a tabular main body portion corresponding to the atomizing base. The atomizing base is fixed on the atomizing body by the fixing member, and after the atomizer is connected and assembled with a power supply assembly, an adsorption force between the tabular main body portion and the magnet can increase.

A dispenser assembly comprising a nasal fluid dispenser device having a reservoir forming body (10) containing fluid or that supports such a reservoir in stationary manner, a dispenser head (20) being assembled on said body (10), said dispenser head (20) being provided with a dispenser orifice (21), said assembly further comprising a positioner member (40) that co-operates with said nasal dispenser device, said positioner member (40) including at least a first facial bearing zone (42) that, during actuation, co-operates with the forehead or the bridge of the user's nose, said dispenser head (20) being movable axially relative to said body (10), said positioner member (40) including at least one hollow sleeve (41) in which said dispenser head (20) is inserted in clamping manner, said positioner member (40) including a second facial bearing zone (46) that is adapted to co-operate with the user's top lip.

A device for controlling respiration during sleep based on the user physiological characteristic. The device includes an odor disperser for dispersing an odor; at least one detector for detecting a physiological characteristic of a user; and a controller for controlling respiration of the user by instructing the odor dispenser to disperse an odor responsive to detections by the at least one detector.

Methods and devices for providing liquids to nasal and/or paranasal cavities are disclosed. Probe portions of a first and of a second probe are introduced to a user's first and second nostril, respectively. Each probe has a primary channel and a secondary channel. Fluid is provided to the secondary channels to expand the expandable portions of the secondary channels, seal the nostril openings and expand alar sidewalls of the nostrils. This may reveal ducts that lead to the paranasal cavities. The liquid is provided through the primary channels to the nasal cavity, the liquid being disposed to reach and stimulate the soft palate, and may trigger a swallow reflex to raise the soft palate and exert pressure to the liquid, the liquid may find an escape route through the ducts and into the paranasal cavities.

A nasal EPAP dilator is employed as an intranasal device which effect differing degrees of inhibition/easing for exhalation/inhalation. A nasal dilator incorporates an outer housing that functions as a pair of connected mirror image nasal dilators, combined with a differential-action valve mechanism modulating the airflow through the passages defined by the dilators, when inserted. The valve greatly inhibits exhalation, while opening easily to inhalation which in combination with the dilating effect is thereby eased over the absence of the nasal dilator. The nasal dilator housings include spars or a screen for structural support and a stoppage mechanism for the valves and to moderate the degree of movement of a plurality of valves so that the valves can open for inhalation, and are restrained to mostly close during exhalation.

A nostril covering device, including a first nostril insert, including a first filter body to filter at least one pathogen from air moving therethrough, and a first flap cover movably disposed on at least a portion of the first filter body to cover the first filter body in response to the air moving from outside a boundary of the first flap cover toward the first filter body, and open at least partially away from the first filter body in response to the air moving from the first filter body toward outside the boundary of the first flap cover, a second nostril insert, including a second filter body to filter the at least one pathogen from the air moving therethrough, and a second flap cover movably disposed on at least a portion of the second filter body to cover the second filter body in response to the air moving from outside a boundary of the second flap cover toward the second filter body, and open at least partially away from the second filter body in response to the air moving from the second filter body toward outside the boundary of the second flap cover, and a nose clip removably connected to the first filter body and the second filter body to form a clamp therebetween.

A method for delivering nitric oxide therapy to a subject can include administering a composition including a nitric-oxide releasing agent and silica to the subject and releasing a therapeutic amount of nitric oxide from the composition.
