Abstract: A sealing interface includes an inner cushion and an outer sheath. The outer sheath substantially seals against the facial contours of the user. The inner cushion and the outer sheath each have a nasal bridge region, left and right cheek regions and either one of an upper lip region or a chin region. In use these regions are aligned with the corresponding nasal bridge region, left and right cheek regions and either the upper lip region or the chin region of a user. The inner cushion includes a hinged region. The hinged region is adapted to flex substantially independently of the inner cushion cheek regions.

Abstract: A mask frame, comprises a central conduit connection aperture and lateral arms having a 3-D curvature. The lateral arms extend: outwardly from a center of the frame, rearwardly, towards the patients ears, and upwardly, along a vector passing from below the nose to a point between the temple the top of the ear. The lateral arms “twist” along their length, such that a bottom margin of an end of each lateral arm is positioned further away from a notional vertical plane passing through the centre of the conduit connection aperture than a top margin. Also provided is an anti-rotation feature which limits or prevents rotation between straps of a headgear, and the mask frame. Further provided is a buckle for a closed loop headgear the buckle being formed with a plurality of openings and posts configured to form an angled headgear strap path through the buckle through which part of a headgear strap loop can pass.

Abstract: A mask assembly is provided comprising a cushion with a proximal face contacting portion, a distal inlet aperture, and a side wall between the proximal face contacting portion and the distal inlet aperture, a frame; and an inlet connector configured to connect to a source of pressurised gas. The frame comprises upper and lower headgear connectors both of which are below the cushion uppermost portion. The frame comprises a central connection portion removably connected to the cushion and the inlet connector. The central connection portion is relatively inflexible, whilst the remainder of the frame may be relatively flexible. The inlet connector comprises an inlet port for connection to a gas delivery conduit, and comprises a downwardly directed central axis.

Abstract: The present disclosure relates to the field of malodour counteraction. More particularly, it concerns the use of volatile compositions to limit, decrease or eliminate the perception of fecal malodour. Such compositions include a malodour antagonist system associated with perfuming ingredients performing as malodour counteractant, in a combination that significantly reduces the perception of fecal malodour. Such compositions, their use in combination with delivery systems and their applications in consumer products are objects of the present disclosure.

Abstract: An interface for positive pressure therapy includes a mask assembly, a headgear assembly and a connection port assembly. The mask assembly comprises a seal member that has an upper portion movably connected to an integrated lower portion, wherein the upper portion rolls during hinging movement of the upper portion relative to the lower portion. The headgear assembly allows connection to the mask assembly in a direction substantially normal to a direction of strap tension. The connection port assembly includes a swivel elbow with a valve member that controls flow through a port that opens toward the user.

Abstract: An interface for positive pressure therapy includes a mask assembly and a headgear assembly. The mask assembly comprises a mask seal that is adapted to underlie the nose. The mask seal extends up the lateral sides of the nose. The mask seal has a primary seal below the nose and a secondary seal alongside the nose.

Abstract: A respiratory mask can include one or a plurality of force sensors configured to detect a force imparted to a user's skin. Output from the one or more sensors can be represented in a way useful to the patient or healthcare provider for adjusting the mask to achieve a desired fitment. A representation of the detected forces can be displayed on a separate display device or on the mask.

Abstract: A patient interface, including a mask assembly and a headgear assembly, provides improved facial sealing and improved ease of use. The mask assembly includes an inflating or ballooning seal. The seal can be secured between two portions of a snap-fit exoskeleton. The headgear assembly connects to the mask assembly with flexible straps during course fitting and with more rigid straps following course fitting. The straps include holes that fit over a tapering post on the mask assembly.

Abstract: The present invention relates to the field of malodor counteraction. More particularly, it concerns malodor masking ingredient having an indane moiety (as defined in formula (I)), as well as malodor masking compositions comprising such ingredients.

Abstract: Patient interface components and/or associated head gear and adjustment systems improve sealing and/or patient comfort and/or ease of use. The interface includes an inflating or ballooning seal. The headgear assembly can be connected to the interface with an elastic component and an inelastic component. The elastic component enabling a course fitting of the interface to the patient and the inelastic component enabling a final fitting of the interface to the patient.

Abstract: A headgear assembly can include a pair of opposing, semi-rigid side arms. Each side arm can be pivotally coupled to an interface at a single location. Each side arm can extend from the single location across the user's cheeks and above the user's ears in use. The headgear assembly can include a top strap coupled to the pair of opposing, semi-rigid side arms, the top strap configured to extend around the top of a user's head. The headgear assembly can include a rear strap coupled to the pair of opposing, semi-rigid side arms, the rear strap configured to extend around the rear of a user's head. The headgear assembly can include a chin strap coupled to the pair of opposing, semi-rigid side arms, the chin strap configured to extend around the user's chin.

Abstract: Embodiments disclosed herein provide various systems and methods for producing dried-recovered household food (DRHF) from organic matter that has been preprocessed by an organic matter processing apparatus (OMPA). The OMPA can convert organic inputs into a ground and selectively dried product, referred to herein as OMPA output. A DRHF processing facility can convert OMPA output, received from many different households, into DRHF. The DRHF facility conducts extensive data acquisition and analysis of OMPA output and DRHF at many different stations existing within the DRHF processing facility. A chain of custody, starting with receipt of OMPA output from households throughout a conversion process in which the OMPA output is converted to DRHF is maintained to ensure that the production of DRHF and the DRHF itself satisfies requirements for food safety and handling, thereby allowing the DRHF to be used as feed or as a feed ingredient.

Abstract: A headgear for a respiratory mask has first and second straps configured to be connected to each other by first and second buckles. The straps are configured to overlap in a region that contacts the rear of a user's head. The overlapping regions of the first and second straps can be positioned in a bifurcated configuration to improve stability on a user's head. The first and second buckles can feature a glider end through which one of the first and second straps can slide and a strap attachment end to which the other strap is permanently connected. In some embodiments, the first and second buckles have two components that are pivotally connected to allow adjustment of the headgear size whilst in a bifurcated configuration.

Abstract: The aspects presented herein provides malodor masking compositions and/or ingredients, methods for counteracting or masking malodors, and perfuming compositions having odor masking properties.

Abstract: A headgear system and/or an interface assembly incorporating a headgear system that, in some configurations, is configured to transform from elasticated or “stretchy” behavior to “inelastic” behavior at least in response to normal or expected forces encountered during the intended therapy. In some configurations, upon fitment to the head of a user, the system automatically adjusts toward or to an appropriate size. A headgear portion or assembly for use in combination with a breathing apparatus in some configurations is at least substantially inelastic and is three dimensional in shape. The headgear portion or assembly can comprise a plastic core and a textile casing. The headgear, or part thereof, may also have integrally moulded labels, connectors, adjustment mechanisms and/or grips.
