Abstract: The present invention provides a gas delivery device and system and methods for delivering humidified pressurized gas through a conduit to a subject. The configuration of the elements of the gas delivery device enable the device to be conveniently oriented from a horizontal to vertical position to suit the needs of a user. The gas delivery device may incorporate a Helmholtz resonator for dampening sound of the motor. The conduit may incorporate concentric tubes to allow it to conveniently engage the humidifier at a single aperture. The invention includes a method of operating a blower motor for a gas delivery device using a single Hall sensor.

Abstract: The present invention is a breathing mask that is fully adjustable so as to enable a comfortable and leak proof seal around a patient's face. The mask includes a frame, a cushion, a hose connector, a strap, connector, a strap, and a headgear. The present invention ensures both comfort and effectiveness by enabling a full adjustment of various components such as the angle of the strap relative to the face mask and the adjustment of the size of the headgear. Furthermore, the present invention also allows for the free rotation of certain elements in order to maintain a sufficient seal without increasing the pressure applied to the patient.

Abstract: A void former particularly for use with a lifting anchor cast into a concrete component is of two piece construction comprising a flexible element and a separate body which is substantially rigid. The flexible element is engageable with the head of the lifting anchor and is maintained in position by the rigid body which also acts to maintain the shape of the void during casting. After casting the rigid body is removed from the flexible element to thereby permit the flexible element to be disengaged from the lifting anchor by manipulation. The void former is thereby removable after casting without destruction of the void former and is thereby suitable for repeated use.

Abstract: The invention provides a nasal cushion for a mask assembly for delivering pressurised gas to the nose of a subject for treatment with continuous positive air pressure. The nasal cushion includes a self-supporting side wall defining a nose-receiving cavity; the side wall extending from a first end to a second end. The side wall is formed continuously with a thin membrane extending inwardly from a second end of the side wall into the nose-receiving cavity for sealingly engaging the nose, upper lip and cheeks of a subject. The side wall has continuously varying thickness. The first end of the side wall is adapted to engage a mask frame. The invention further provides a mask assembly for delivering pressurised gas to a patient, the assembly including a nasal cushion for sealing against the nose, cheek and-lip area the nasal cushion as described, a frame for receiving the nasal cushion, and a headgear, the headgear including a rigid arm for positioning behind the ear of a patient.

Abstract: An erectable, collapsible frame (2) for a shelter (1), the frame (2) being erectable to support a canopy (3) in order to form the shelter. The frame (2) includes at least 3 legs (4), and a perimeter support assembly (12) extending between and interconnecting adjacent legs (4). A canopy peak support assembly (28) extends outwardly from the legs (4), when the frame (2) is erected, to define an underlying shelter space (S). The legs (4) and support assemblies (12,28) are pivotably interconnected to enable unfolding and folding for respective erection and collapse of the frame (2). A shelter (1) incorporating the frame (2) and canopy (3) is also disclosed.
