Abstract: An aerosol medicament delivery adapter comprises a first conduit, second conduit and a diverter element. The first conduit encloses a flow path chamber and extends between an upstream first end and a downstream second end. The second conduit comprises an aerosol medicament delivery conduit that includes an upstream first end adapted to be fluidly coupled to a particle generator, and a downstream second end luidly coupled to the first conduit at a Y-junction proximate the upstream first end of the first conduit. The diverter element comprises a flow diverter chamber disposed within the first conduit or the second conduit. The cylindrical flow diverter chamber includes a transitional flow cross-section and a principal axis, extending between a first end and a second end thereof. The diverter element creates flow eddies for enhancing an entrainment of aerosol particles, delivered via the second conduit, within a pressurized gas flow along the flow path within the first conduit.

Abstract: An aerosol medicament delivery adapter (20) comprises a first conduit (22), second conduit (24) and a diverter element (26). The first conduit (22) encloses a flow path chamber (28) and extends between an upstream first end (34) and a downstream second end (36). The second conduit (24) comprises an aerosol medicament delivery conduit that includes an upstream first end (48) adapted to be fluidly coupled to a particle generator (14), and a downstream second end (50) fluidly coupled to the first conduit at a Y-junction (54) proximate the upstream first end of the first conduit. The diverter element (26) comprises a flow diverter chamber (60) disposed within the first conduit (22) or the second conduit (24). The cylindrical flow diverter chamber (60) includes a transitional flow cross-section (62) and a principal axis (64), extending between a first end (66) and a second end (68) thereof.

Abstract: A cushion (16) for use with a mask (10) in delivering a flow of breathing gas to a user includes a first portion adapted to contact a surface of a user, a second portion adapted to be coupled to a mask shell (18), and a wall portion extending between the first portion and the second portion. The wall portion includes a chamber formed therein, the chamber having one of an electro-rheological fluid or a magneto-rheological fluid disposed therein. The cushion further includes a means (44, 50) for selectively varying the apparent viscosity of the fluid disposed within the chamber.

Abstract: A patient interface device (10) includes a patient sealing assembly (60) including a cushion (70), and a frame member (80) coupled to the cushion, and an adjustable forehead support assembly (200) provided at the distal end (120) of the frame member. The adjustable forehead support assembly includes an adjustment mechanism (202) coupled to a forehead cushion (204), wherein the adjustment mechanism includes a forehead cushion support member (212) having a base portion (216) coupled to the forehead cushion and an vertical/upright rotatable wheel member (214). Rotation of the wheel member causes movement of the frame member and the cushion relative to the forehead cushion.

Abstract: A patient interface device includes a patient sealing assembly having a cushion and a frame member having a faceplate portion and an extension portion extending from the faceplate portion. The cushion is coupled to the faceplate portion. A forehead member engages the forehead of the patient, and a flexible elongated member is coupled to the extension portion. A drive assembly selectively causes the second end portion of the flexible elongated member to move relative to the extension portion in a first direction. Movement of the flexible elongated member relative to the extension portion in the first direction causes movement of the frame member relative to the forehead member in a second direction transverse to the first direction.

Abstract: A patient interface device includes a patient sealing assembly adapted to communicate a flow of breathing gas within an airway of a patient, a fluid coupling conduit fluidly coupled to the patient sealing assembly, the fluid coupling conduit being structured to receive the flow of breathing gas and communicate the flow of breathing gas to the patient sealing assembly, and a headgear component structured to secure the patient interface device to the patient's head, the headgear component including a strap member having a generally C-shaped connector member. The generally C-shaped connector member is structured to at least partially wrap around and be releasably received and held by or within a receiving feature provided on one of: (i) the fluid coupling conduit, and (ii) an extension member extending outwardly from the patient sealing assembly.

Abstract: A patient interface device is provided that includes a patient sealing assembly, such as a mask having a rigid shell and a cushion coupled to the rigid shell, and a forehead support movably coupled to the patient sealing assembly. The forehead support is moved by an wedge-type adjustment mechanism such that linear translation of the wedge moves the forehead support among the plurality of positions and fixes the forehead support in a desired position among the plurality of positions.

Abstract: A connector (100) for a respiratory mask (10) including a first end portion (110) removably connected to the respiratory mask, a second end portion (120)removably connectable to a non-invasive ventilation (NIV) tube (40), and an elbow portion (130) disposed between the first and second end portions. The elbow portion includes a port (140) for removably receiving an endotracheal tube (50), the port including a removable seal (450) that maintains non-invasive ventilation during insertion of the endotracheal tube into the respiratory mask through the port. At least one of the first end section, the second end section and the port are openable for removal of the connector from around the inserted endotracheal tube.
