Publication number: 20100024825Abstract: 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.Type: ApplicationFiled: August 6, 2009Publication date: February 4, 2010Inventors: Nicholas Charles Alan SMITH, Alastair Edwin McAULEY, Chris Earl NIGHTINGALE, Ivan MILIVOJEVIC, Lewis George GRADON

Patent number: 7096867Abstract: The present invention is related to patient interfaces, such as nasal masks (2), 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 (601) releasably attaching the interface to headstraps wherein the securement means (601) is slidably engaged with the patient interface. In a second form of the invention the mask headgear is formed of a plurality of straps (701, 702) 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 (802) that engage the patient interface with the headgear straps.Type: GrantFiled: October 25, 2002Date of Patent: August 29, 2006Assignee: Fisher & Paykel Healthcare LimitedInventors: Nicholas Charles Alan Smith, Alastair Edwin McAuley, Chris Earl Nightingale, Ivan Milivojevic, Lewis George Gradon

Patent number: 7066174Abstract: 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.Type: GrantFiled: September 14, 2000Date of Patent: June 27, 2006Assignee: Fisher & Paykel Healthcare LimitedInventors: Nicholas Charles Alan Smith, Alastair Edwin McAuley

Patent number: 7017576Abstract: 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.Type: GrantFiled: August 22, 2003Date of Patent: March 28, 2006Assignee: Fisher & Paykel Healthcare LimitedInventors: Gregory James Olsen, Martin Leckie, Neil Prime, Lewis George Gradon, Nicholas Charles Alan Smith, Alastair Edwin McAuley, Mark Joseph Haycock, Chris Earl Nightingale

Patent number: 6997186Abstract: 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 formed from a very supple material and is dimensioned to extend laterally into the buccal vestibule and vertically to overlap the gums. A gases pathway is provided through the vestibular shield and may include a hard plastic insert through the shield. A connection for connecting the mouthpiece to a breathing circuit is provided which reduces the transfer of forces caused by movement therebetween.Type: GrantFiled: October 22, 2004Date of Patent: February 14, 2006Assignee: Fisher & Paykel Healthcare LimitedInventors: Christopher John Robertson, Nicholas Charles Alan Smith, Lewis George Gradon

Patent number: 6951218Abstract: 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. A forehead rest with a horizontal pivot that is attached to the mask is disclosed. An outlet vent to reduce the noise from exhausted carbon dioxide is described. A mouthpiece is also described with an outlet diffuser including Heat Moisture Exchanger Material.Type: GrantFiled: March 24, 2003Date of Patent: October 4, 2005Assignee: Fisher & Paykel Health Care LimitedInventors: Lewis George Gradon, Nicholas Charles Alan Smith, Alastair Edwin McAuley, Mark Joseph Haycock, Chris Earl Nightingale, Daniel Mahon

Publication number: 20040065327Abstract: 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.Type: ApplicationFiled: September 30, 2003Publication date: April 8, 2004Applicant: Fisher & Paykel Healthcare LimitedInventors: Lewis George Gradon, Nicholas Charles Alan Smith, Alastair Edwin McAuley, Mark Joseph Haycock, Chris Earl Nightingale
