Mask assembly

InactiveUS6823869B2Breathing masksRespiratory masksPositive airway pressureHermetic seal

A respiratory mask assembly for use in the delivery of non-invasive positive airway pressure to a user. The assembly includes a rigid shell having a channel portion defined by an inner wall, an outer wall and a channel floor, a face-contacting cushion acting to space the shell away from the user's face and a sealing tab extending from the cushion to engage a portion of the shell to provide a continuous airtight seal between the cushion and the shell. A retaining ring within the mask assembly is configured to secure the cushion to the shell. The retaining ring has a first portion including at least one clip configured to pass through at least one slot portion such that an underside surface of the at least one clip engages a section of the shell when the retaining ring is positioned within the channel.

Cushion for a respiratory mask assembly

ActiveUS7523754B2More comfortableAvoid Sealing ProblemsChemical protectionHeat protectionChinRespirator

A respiratory mark assembly for delivering breathable gas to a patient includes a frame and a cushion. The cushion has a non-face contacting portion structured to be connected to the frame, a face-contacting portion structured to engage the patient's face, and an intermediate portion that interconnects the non-face contacting portion and the face-contacting portion. The intermediate portion includes a gusset portion that applies a first component of force to the patient's face through the face-contacting portion. A spring structure is coupled with the face-contacting portion of the cushion. The spring structure applies a second component of force to the patient's face through the face-contacting portion. The first and second components of force applied by the gusset portion and spring structure, respectively, determine a contact force of the cushion applied to the patient's face through the face-contacting portion. The intermediate portion may also include an elastic cuff portion. Further, in the case of an oral mask, the sealing section may include a portion that is designed to promote a better seal in the chin region of the mask.

Cushion for a Respiratory Mask Assembly

ActiveUS20070215161A1More comfortableEffectively seals regionBreathing masksRespiratory masksBreathing gasEngineering

A respiratory mask assembly for delivering breathable gas to a patient includes a frame and a cushion. The cushion has a non-face contacting portion structured to be connected to the frame, a face-contacting portion structured to engage the patient's face, and a central portion that interconnects the non-face contacting portion and the face contacting portion. The frame may be structured to allow a forehead support to assume multiple positions, to compensate for replacement cushions that may have a different profile, shape or size. The cushion is structured to compensate for variations in strap tension, treatment pressure and/or movement of the patient. Headgear may be provided with a strap assembly in which one or more straps is provided with selectively adjustable elasticity or extensibility that may be automatically changed in dependence of treatment pressure and/or treatment type.

Respiratory mask

ActiveUS20100313891A1Solve the small frictionWeight bulkRespiratory masksBreathing masksNoseRespiratory mask

A respiratory mask for use with a patient, and that is suited for use with children, includes a flexible cushion arranged to interface with and deliver air to the patient's nose. The cushion has a tube connection portion at one or both sides adjacent the patient's nares, the tube connection portion being arranged to connect to an air delivery tube. This location, plus the very low profile of the mask, allows a patient (e.g. an infant) to sleep on their face more comfortably. A more rigid support structure adjacent the cushion is provided to stabilize the cushion and prevent it from collapsing. Headgear is also provided and arranged for releasable attachment to the support structure.

ActiveUS7743767B2Comfortable patient interfacePatient compliance is goodChemical protectionHeat protectionEngineeringRespiratory mask

A respiratory mask assembly for delivering breathable gas to a patient includes a frame having a front surface and a rear surface, opposite the front surface, and adapted in use to face the patient. The frame defines an inner wall and an outer wall extending from the rear surface, the inner and outer walls being spaced to define a channel therebetween. A cushion is removably attachable to the frame such that the cushion and frame are repeatably engagable with and disengagable from one another. The cushion includes a side wall to be inserted into the channel of the frame, the side wall having a first interlocking surface that engages a second interlocking surface provided in the channel when the cushion and frame are engaged with one another. The first and second interlocking surfaces interlock with one another to removably attach the cushion to the frame.

Respiratory mask

InactiveUS6851428B2Adjustable sizeEasy to adjustBreathing masksRespiratory masksNebulizerFolded form

A respiratory mask is reduced in size to better fit patients with smaller faces by either (a) folding one or more accordian folds formed in an upper portion of the mask, or (b) tearing away a part of the upper portion of the mask. The respiratory mask for adult patients can thus be adjusted to fit smaller adults and larger children. The respiratory mask for children can thus be adjusted to fit smaller children. A ball joint swivel connector is provided to connect the gas inlet of the masks to the hose connection for respiratory or nebulizer treating gases or aerosols.

Nose breathing mask for a medical patient; and method

InactiveUS20050051171A1Less cumbersomeEasy to removeBreathing filtersBreathing masksNoseNose breathing

A medical apparatus and method for medical patients that suffer from Sleep Apnea. A breathing mask that fits comfortably over a nose area. Because a mask is shaped to a face, it is less bulky and cumbersome over the nose area. Inside a shell of a mask, towards a patients' face, is a silicone wax lining that is on the inner rim of a shell and parameters to enclose a nose as a seal. A silicone wax substance is novel to a device because of its ability to retain a form it has been molded into. A silicone wax lining around a nose allows a patient to form and mold a substance against a face and provide an air-tight seal. A single strap is used to fasten and secure a mask to a face. Tabs or buckle can be used to fasten a strap.

Respiratory Mask

InactiveUS20080302365A1Rigid enoughProvide dimensional stabilityChemical protectionHeat protectionFast releaseAdhesive

A respiratory mask having a shell and a cushion that is adhered to a user's face is sufficiently rigid to provide dimensional stability and a constant volume between the respiratory mask and the user's face, while also being comfortable and conformable to a user's individual facial features. The respiratory mask may cover the nose, the mouth, or both of the user and is useful for respiratory therapies including sleep apnea. The respiratory mask may have a quick release mechanism such as a pull tab that tears a portion of the mask when pulled to allow access to the user's breathing passage or a pull string embedded in the adhesive that breaks the seal between the adhesive and the user's face when pulled.
