Abstract: The present invention relates to adjustable flow control valves, for example to an Adjustable Pressure Limiting (APL) valve. The adjustable valve (2) described comprises a valve body (4) comprising a valve seat (6), a valve member (10) movable relative to the valve seat (6), a first valve cap (20), a second valve cap (50) and a biasing element (30) to bias the valve member (10) away from the first valve cap (20). The first valve cap (20) is movable to increase the biasing force applied by the biasing element (30). The second valve cap (50) is engageable with the first valve cap (20) to prevent such movement of the first valve cap (20) beyond a selected position, but to allow movement of the first valve cap (20) in an opposite direction, way from said position.

Abstract: A sealing cushion for a respiratory mask assembly has a patient interface portion having a resiliently deformable membrane for engagement with a patient's face, and an aperture formed therein for receiving a nasal and/or mouth region of the patient's face. An inner surface of the deformable membrane comprises a plurality of projections arranged in separate groups of projections positioned in a plurality of localized regions of the deformable membrane. The projections in each of the separate groups of projections are arranged such that each projection in the group of projections engages with an adjacent projection in the group of projections when the deformable membrane is deformed during engagement of the deformable membrane with the patient's face, in use, thereby providing the deformable membrane with an increased resistance to further deformation.

Abstract: A laryngoscope (10) having a body (20, 42) including a handle, a laryngoscope blade (22) extending from a distal end of the body (20, 42), and a display screen housing (18) extending from a proximal end of the body (20, 42). The laryngoscope (10) has at least one unitary housing component (12) that defines at least a portion of each of the body (20, 42), the laryngoscope blade (22) and the display screen housing (18).

Abstract: An intubation aid (10) for insertion into an endotracheal tube (30) has a cross-sectional shape having at least one vertex defining a longitudinally extending edge. The intubation aid (10) is supported within the endotracheal tube (30), in use, by the longitudinally extending edge.

Abstract: There is provided an oral hygiene swab (10) for a patient. The swab has a stem (12) formed of a first relatively rigid material and a head portion (14) formed of a second relatively softer material overmoulded onto the stem. The second material of the head portion is shaped to provide outwardly protruding cleaning formations (32, 36) for contact with the patient's mouth. The swab may be a suction swab and the stem may have a hollow interior.

Abstract: Apparatus (10,226,326) for condensing water from respiratory gases, comprising a heat exchange component (20,234,334) having an inlet (22,228,328), an outlet (24,228,230) and a condensation chamber, the inlet and outlet (22,24,228,230,328,330) being connectable to a breathing system, such that respiratory gases are conveyed through the condensation chamber, in use, and a base unit (30,232,332) adapted to aid removal of heat from the walls of the heat exchange component (20,234,334), wherein the heat exchange component (20,234,334) is releasably engageable with the base unit (30,232,332), such that the heat exchange component (20,234,334) is replaceable.

Abstract: A respiratory connector is provided for connecting corresponding ends of a plurality of gas flow lines to a corresponding plurality of ports. The connector comprises first and second connector formations, and a bridge extending between the first and second connector formations. The bridge is actuable to allow a spacing between the first and second connector formations to be varied during use.

Abstract: A respiratory device for delivering gas to a patient comprises a gases passageway having proximal and distal ends, and a supplementary gas inlet in a side wall of the gases passageway. The supplementary gas inlet is adapted to direct gas along an interior surface of the gases passageway, such that the gas follows a generally helical path towards the distal end of the gases passageway.

Abstract: An airway device for human or animal use includes an airway tube having a first end and a second end, the first end of which is surrounded by a laryngeal cuff configured to fit over the laryngeal inlet of a patient when in situ. The first end of the airway tube is provided with an intubating ramp configured to direct a tube inserted through the airway tube into the laryngeal inlet of the patient when in situ.

Abstract: A valve assembly comprising a fluid conduit (11,18) having an inlet and an outlet, and a valve seat (24) adapted to be engaged by a valve member (40) for controlling the flow of fluid through the outlet of the fluid conduit (11,18), wherein the valve assembly is defined by at least a valve body component (10) and a valve seat component (20) engaged therewith, the valve body component (10) defining at least part of the fluid conduit (11,18), and the valve seat component (10) defining at least the valve seat (24).

Abstract: A patient interface assembly comprising a patient interface, a connector for connecting the patient interface to a conduit, and a conduit joined to the connector in a non-releasable manner. The patient interface comprises a first connection formation and the connector comprises a second connection formation, the patient interface and the connector being connectable such that, in a connected configuration, the first connection formation and the second connection formation are engageable with each other, with a snap fit, to provide a non-releasable connection.

Abstract: A chemical absorbent comprising a hydrated mixture of a major proportion of a pharmaceutically acceptable hydroxide of a Group II metal and a minor proportion of a Group I metal-containing zeolite. The chemical absorbent is substantially free of hydroxides of Group I metals.

Abstract: There is provided an apparatus for controlling fluid flow, comprising a first component for holding or conveying fluid, the first component having a port for the passage of fluid, a fluid passageway (18) from the interior of the first component to the exterior of the first component through the port, a contact valve (1) located in the fluid passageway (18), a second component having an abutment means, and connecting means for connecting the second component to the first component, the contact valve (1) comprising a first valve arm (8) extending into the fluid passageway (18), the first valve arm (8) being movable between an open position in which fluid flow through the fluid passageway (18) is substantially permitted, and a closed position in which fluid flow through the fluid passageway (18) is substantially prevented, wherein, when the second component is connected to the first component, the abutment means moves the first valve arm (8) into the open position.
