The present invention relates to a device for delivering a supply of gases to a patient. The device includes a patient interface and connecting member. The connecting member is preferably a L-shaped swiveled connector that is capable of being fixed into one of two positions, a first position where the connector is freely rotatable within the patient interface, and a second position where an interference between the interface and connector prevents the free rotation of the connector within the patient interface. The present invention further relates to a connector that has outlet means, which includes at least one outlet vent and a funnel, which in use directs and passes a substantial portion gases expired from the patient through the outlet vent or vents.

Patient interfaces

The present invention relates to a device for delivering a supply of gases to a patient. The device includes a patient interface and connecting member. The connecting member is preferably a L-shaped swiveled connector that is capable of being fixed into one of two positions, a first position where the connector is freely rotatable within the patient interface, and a second position where an interference between the interface and connector prevents the free rotation of the connector within the patient interface, The present invention further relates to a connector that has outlet means, which includes at least one outlet vent and a funnel, which in use directs and passes a substantial portion gases expired from the patient through the outlet vent or vents.

A CPAP system for supplying humidified gases to a user is disclosed in which various interfaces are described for gas delivery. A mask cushion including a deformable cushion and thin sheath is described.

Breathing assistance apparatus

The present invention relates to a device for delivering a supply of gases to a patient. The device includes a patient interface and connecting member. The connecting member is preferably a L-shaped swivelled connector that is capable of being fixed into one of two positions, a first position where the connector is freely rotatable within the patient interface, and a second position where an interference between the interface and connector prevents the free rotation of the connector within the patient interface. The present invention further relates to a connector that has outlet means, which includes at least one outlet vent and a funnel, which in use directs and passes a substantial portion gases expired from the patient through the outlet vent or vents.

The present invention is a mask for the delivery of gases to a patient. The mask has a hollow body and a cushion that seals against the user's face. The cushion is comprised of an inner resilient cushion and an outer flexible sheath. The cushion preferably extends below the patient's chin when in use.

The present invention is related a nasal positive airway pressure device. The nasal device utilizes an engagement means located about nasal cannulae to engage and secure the cannulae within the nares of a patient. The engagement means is a nasal scaling flap. The flap in its natural bias is tapered, the wide-open end of which is shaped to conform to the facial contours of a patient's nose around the outside of the nose. Thus in a closed form, the flap provides a cup-like device that is fitted around the patient's nose and prevent the nasal device from falling from the patients nose. In the open form, which allows for placement and fitting of the nasal device, the flap is intended to be in a bent back position to aid insertion of the nasal cannulae into the patient's nares.

Nasal positive pressure device

The present invention is related to patient interfaces, such as nasal masks (), particularly though not solely for use in providing continuous positive airway pressure therapy or positive pressure ventilation to patients suffering from obstructive sleep apnoea. In a first form the invention is a patient interface that has securement means () releasably attaching the interface to headstraps wherein the securement means () is slidably engaged with the patient interface. In a second form of the invention the mask headgear is formed of a plurality of straps () where at least one of the plurality of straps is slidably engaged with another of the plurality of straps. In a further form the patient interface may be provided with vertically adjustable engaging means () that engage the patient interface with the headgear straps.

Nasal masks

A valve for use in a CPAP system or any stem at a pressure above ambient which vents the pressurised gases from the blower during expiration. Due to the pressure-flow characteristics of the blower this results in the patient having a much lower airway pressure during expiration making breathing easier. The valve includes a movable member which blocks flow from the blower to the patient during exhalation and vents externally. During inhalation gases flow normally from the blower to the patient.
