Abstract: In accordance with at least one exemplary embodiment, a cushion for a ventilation interface is disclosed. A ventilation mask can include a mask body adapted to matingly engage with the cushion. The cushion can be a double-membrane cushion having an outer sealing membrane and an inner membrane, both of which can extend from a frame. The outer sealing membrane can have a face-contacting portion. The inner membrane can be outwardly oriented from the frame.

Abstract: A nasal ventilation interface and method for providing nasal ventilation to a patient includes a hybrid face mask, covering only the mouth, coupled with removable nasal inserts extending from the upper surface of the mask. The nasal interface has modular, removable, and disposable nasal pillows connecting the upper surface of the mouth-portion of the mask to the user's nares. Each part of the hybrid mask is modular and can be formed in various shapes and sizes. The ventilation interface has differing gas line entry ports and can be shallow with a relatively deep soft facial interface or deep with a relatively shallow facial interface. In either case, the upper surface receives the nasal interface. The upper surface can have a removable ceiling in which is defined a nasal interface connector. The nasal interface can be integral with a removable ceiling. The entire hybrid mask can be made in one piece.

Abstract: A ventilation interface device is disclosed that may include a hollow cannula, at least one nasal insert and at least one exhaust port or may include a mask designed to cover a user's nose, mouth or both nose and mouth. The at least one nasal insert may be formed so as to fit in any size nares of any user and may be detachable. Additionally, the at least one exhaust port may be in any of a variety of orientations and, in some embodiments, contain sealable ports.

Abstract: A ventilation interface may include the following elements: a cushion, shell, forehead support, supply tubes, an adapter or Y-connector and a nasal cannula, which may also include nasal inserts, and connectors. Each of the elements of the ventilation interface may also include ribs of wire, stiffener or other bendable material having a greater rigidity than the material composing the main body of each element. These bendable portions may be capable of retaining multiple desired bent shapes in multiple desired directions.

Abstract: In accordance with at least one exemplary embodiment, a ventilation system for providing gas under a first pressure to the nose of a user and second pressure to the mouth of a user is disclosed. A ventilation system can include a flow generator that can be connected to a gas supply tube. The gas supply tube can be in fluid communication with a ventilation interface. At least a portion of the gas supply tube can have a divider within the channel of the tube forming a nasal passageway and an oral passageway. A nasal breathing chamber and an oral breathing chamber can be defined in the ventilation interface. The nasal breathing chamber can be in fluid communication with the nasal passageway. The oral breathing chamber can be in fluid communication with the oral passageway.

Abstract: In accordance with at least one exemplary embodiment, a cushion for a ventilation interface is disclosed. A ventilation mask can include a mask body adapted to matingly engage with the cushion. The cushion can be a double-membrane cushion having an outer sealing membrane and an inner membrane, both of which can extend from a frame. The outer sealing membrane can have a face-contacting portion. The inner membrane can be outwardly oriented from the frame.

Abstract: Embodiments of the present invention provide a device, system and method for providing mask assemblies for use in the treatment of respiratory conditions and in assisted respirations. In an embodiment of the invention, a respiratory mask assembly can include a mask shell assembly, an inlet connector, a mask cushion and an adjustable forehead support. The mask shell assembly can include a central shell body with an inlet aperture for receiving a delivered amount of gas, and a rear mating edge. The inlet connector can include at least one non-circular exhalation port and can be rotatably disposed around the inlet aperture of the central shell body. The mask cushion can have a front mating edge for attaching it to the central shell body. The adjustable forehead support can have an extension bar, at least one forehead pad, and at least one locking tab that can be coupled to the central shell body.

Abstract: A nasal prong for a ventilation interface can include a guide. The guide can be suitably disposed on portions of a nasal prong. One or more guides on a pair of nasal prongs may assist in operatively positioning and retaining the nasal prongs against or within a user's nares. In at least one exemplary embodiment, a guide can extend from the proximal end of a head portion of a nasal pillow. The guide may extend substantially upward from the nasal pillow. The guide may also be curved partially around a circumference of the nasal pillow. The guide can shroud a normally viewable portion of a user's nose when in use. The guide can abut an outer anatomy of a user's nose proximate a naris. As such, guides can cooperate with outer portions of the nose in which they contact to assist in positioning and retaining nasal pillows.

Abstract: Medicine delivery interface for delivery of therapeutic aerosols or gases, including at least one hollow body having at least one nasal aperture defined therein at least one nasal insert tube associated with each nasal aperture of the hollow body is capable of being inserted into a nostril. The interface also may include at least one exhaust aperture having at least one exhaust valve configured to exhaust exhaled gases and configured to block inflow of air through the exhaust aperture and at least one intake aperture.

Abstract: A ventilation or CPAP interface system adapted to be inserted into a nares of a user to secure the interface. A cannula adapted to be connected to a source of ventilation gas forms a first portion of an input gas flow passage to supply the ventilation gas to the user. A nasal insert adapted to be inserted the nares of the user forms a second portion of the input gas flow passage from the cannula to a distal end of the nasal insert. A seal portion adapted to engage a portion of the first naris is provided adjacent the distal end of the nasal insert. Ventilation interface system may optionally include feed tubes, y-connector, tube holder, and headgear.

Abstract: A soft material replaceably coupled to a ventilation interface, wherein the soft material is positioned between the interface and a user's face to alleviate discomfort. The soft material may be configured to be replaceably couple to various ventilation interfaces which may include CPAP interfaces.
