Abstract: A improved interface is disclosed for delivering CPAP therapy to patients. The interface has a sliding engagement to the headgear. The sliding engagement allows substantial relative lateral movement eg: when face is distorted from sleeping on side, while still providing adequate compressive force to avoid side leakage. The sliding engagement also allows easy release from the headgear.

Abstract: 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.

Abstract: The present invention relates to apparatus for treating sleep apnoea. More specifically, the present invention provides a nasal positive airway pressure device which is reliable and comfortable to wear and, consequently, more acceptable to the patient. The nasal device has inflatable cuffs worn in a patient's nasal cavities. A pair of inflating tubes are in gaseous communication with the interior of a respective one of the inflatable cuffs and when pressurised gases flow through each of the inflating tubes, each of the cuffs inflate to retain the cuff within each of the nasal cavities of the patient.

Abstract: A mouthpiece for oral delivery for oral delivery of CPAP treatment has a vestibular shield for location between the teeth and lips/cheeks of a wearer. The vestibular shield is dimensioned to extend laterally into the buccal vestibule and vertically to overlap the gums. The vestibular shield is formed from a very supple material. A gases pathway is provided through the vestibular shield and may include a hard plastic insert through the shield, including a standard breathing conduit connection at its outer end. A short stub conduit on the outlet side of the shield passes between the wearers upper and lower teeth.

Abstract: A nasal mask is disclosed which is more comfortable for the user to wear and reduces side leakage as compared to masks of the prior art. In a first form headgear for securing a mask to the user's face is disclosed where a section of at least one strap securing a mask to a user's face is substantially more elastic then the remainder of the strap. Headgear of this type allows the user to tilt the head backwards without lateral movement of the mask. In a further aspect, headgear tensioners are disclosed which provides a preset fitting of the mask and ensures that a user cannot over tighten the straps. The tensioners are recalling tension devices attached to the straps and/or mask on either side of the mask. In another form the headgear tensioner is a strap attachment on either side of the mask that allows the straps to move back through the attachment to a predetermined position that provides an appropriate tension between the back of the user's head and mask.

Abstract: A system is disclosed for nasal delivery of Continuous Positive Airway Pressure to a user. The system includes a variable speed fan unit to pressurize the gases, and a humidification unit to provide a controllable level of humidity to the gases. The pressurized humidified gases are transported through a conduit to the user, and arc delivered through a nasal mask to the nasal passages. The oral cavity is sealed against “mouth leak” by insertion of a sealed mouthpiece. The mouthpiece includes an intra-oral sealing means and an extra-oral sealing means substantially sealing the oral cavity of said user. The extra-oral sealing means may be adjusted into one of two conditions, a first condition when said mouthpiece is inserted into said user's mouth being, substantially unengaged with said user's face, and a second condition when correctly positioned in said user's mouth being substantially engaged with said user's face and under compression thereupon.

Abstract: A CPAP system is described for improved respiratory therapy of patients. In particular a patient interface is disclosed with an outlet vent with lower noise levels and more diffused outlet flow over prior art outlet vents. The outlet vent includes a main vent which is diffused and muffled and a higher resistance vent provided in case the main vent is blocked. The outlet vent is removable for easy maintenance and provides indication to the user when maintenance is required. The outlet vent described may be used on nasal masks, mouthpieces and patient interfaces generally.
