A sealing member for sealing an atomizer against undesired leakage of liquid includes a base body and a resisting portion. The base body includes a first surface, a second surface opposite to the first surface, and an outer wall connecting the first surface with the second surface. A vent passes through the first and second surfaces. The resisting portion is disposed on the outer wall and is configured to be compressed against an inner wall of a liquid storage pipe to provide sealing and avoid leakage. An atomizer and an inhalation device are also disclosed.

A method of treatment for mixed carbon dioxide, carbonic acid, saline and optional active additives for treating non-nasal ailments includes delivery of dosage of the treatment at specified flow rates, using a) main housing having a hollow central area containing the dosage; b) a dosage dispenser head located at the distal end of the main housing, and having at least one flow channel for movement of the dosage from the main housing through the dosage dispenser head and to external of the dosage dispenser head; c) a dosage release control component located between the main housing and the dosage dispenser head to permit flow of the dosage through the dosage dispenser head in response to increased pressure against the dosage; and d) a pressure-changing moveable component on the main housing.

Fit testing is conduct to ensure that gas mask provide proper protection to workers that may be exposed to airborne contamination. Standard fit test procedures require the mixing of fit test compounds to specific fit testing composition required for threshold testing and subsequent fit testing. A device is needed for easy mixing of the components of the fit test composition and easy delivery of fit test composition during a fit test. For example, a device for fit testing of a gas mask on an individual wearer may include a sprayer, at least one ampoule containing a fit testing component, and a reservoir containing the ampoule and a solvent for the fit test component. The reservoir may be hollow body having a sealed inner volume. The reservoir may be deformable to break at least one hermetically sealed ampoule without tearing or otherwise breaking the reservoir. Therefore, the ampoule may be broken within the reservoir to mix the gas mask fit testing component into the solvent to generate the desired concentration for either a threshold test or gas mask fit test.

A nasal fluid-spray device having: a reservoir containing at least one dose (D) of fluid; and a dispenser system that, each time the device is actuated, sprays a dose (D) of fluid through a spray orifice, generating a spray that extends axially from the spray orifice. The device further includes a generator system for generating a secondary flow, which generator system is actuated simultaneously with the dispenser system, the secondary flow generator system having a secondary flow channel provided with an outlet orifice, the outlet orifice arranged downstream from the spray orifice, and the secondary flow extending from the outlet orifice along an axis (B) that forms an angle (α) relative to the axis (A) of the spray and that intersects the axis (A), thereby deforming and/or deflecting the spray.

A method and a wash, clean and dry system are provided for washing, cleaning and drying a surface region of a human body. The system includes a toilet seat assembly with a bidet assembly having a spray canister device for spraying the surface region with a solution, such as a skin protecting barrier solution, a cleaning solution or a medicated solution. In one aspect, the spray canister device can be movably insert into and out of the toilet seat assembly and is easy to operate and use. In addition, the bidet assembly further includes a spray nozzle assembly and a drying nozzle assembly, which are adapted to wash, clean and dry the region of the human body in three dimensional moments. The removable spray canister device with the removable sleeved cover element is thus easy to carry and be re-filled with new solutions.

The present invention provides a portable, light-weight, breathing device and methods of use for delivering pristine, fresh air or varying high concentrations of oxygen with or without aroma, i.e., essential oils for stimulating appetite, boosting mood or decreasing stress and anxiety. The breathing device comprises an air container having a breathing air bag therein which contains the fresh air or the varying concentrations of oxygen optionally with the one or more essential oils, tubing for delivering the fresh air or oxygen to a breathing mask, and a plurality of movable valves included in the mask which directs air or oxygen into or out of the mask depending on whether the user is inhaling or exhaling. The breathing device also comprises the use of a can of compressed fresh air or oxygen with or without aroma to be used with an air reservoir or with an expandable air bag.

A nasal delivery device for and a method of delivering substance to a nasal airway of a subject, the nasal delivery device comprising: a mouthpiece (519) through which the subject in use exhales to cause closure of the oropharyngeal velum of the subject; a nosepiece (517) for fitting to a nostril of a subject, the nosepiece including a nozzle (549) through which substance is in use delivered to the nasal airway; and a manually-actuatable substance supply unit (520) for delivering substance through the nozzle of the nosepiece.

A thin ribbon spirally wound polymer conduit and method of forming, wherein a helical reinforcing bead is interposed adjacent overlapping layers of ribbon. Further, a method of continuously forming spirally wound conduit wherein a sacrificial layer, preferably having a different base polymer to that of the conduit, is first applied to the former before the conduit is formed overtop.
