Publication number: 20040177850Abstract: A patient interface for delivering pressurised gases to a user comprising a housing configured to receive gases and deliver them to a user and a forehead rest. The forehead rest is engaged with the housing and has a single area of contact with a user's forehead. The forehead rest includes a bridge portion between the user's forehead and housing allowing a substantially unrestricted view for a user's eyes. The forehead rest is pivotally movable in relation to the housing and can be locked by a friction engagement into position.Type: ApplicationFiled: February 24, 2004Publication date: September 16, 2004Inventors: Lewis George Gradon, Alastair Edwin McAuley, Ivan Milivojevic

Patent number: 6789541Abstract: 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: February 7, 2002Date of Patent: September 14, 2004Assignee: 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

Publication number: 20040079370Abstract: A flow probe for use in a humidification system is disclosed. The flow probe is adapted to be positioned in a humidified gases flow (for example oxygen or anaesthetic gases) such as that which is provided to a patient in a hospital environment. The flow probe is designed to provide both temperature and flow rate sensing of the gases flow by incorporating two sensors (preferably thermistors) and the shape and alignment of the probe enables accurate readings by reducing the occurrence of condensation on the sensors.Type: ApplicationFiled: October 23, 2003Publication date: April 29, 2004Applicant: Fisher & Paykel LimitedInventors: Lewis George Gradon, Stephen William McPhee, Paul John Seakins, Peter John Leonard

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

Patent number: 6679257Abstract: 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: July 31, 2000Date of Patent: January 20, 2004Assignee: Fisher & Paykel LimitedInventors: Christopher John Robertson, Nicholas Charles Alan Smith, Lewis George Gradon

Publication number: 20030094177Abstract: 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: November 13, 2002Publication date: May 22, 2003Inventors: Nicholas Charles Alan Smith, Alastair Edwin McAuley, Chris Earl Nightingale, Ivan Milivojevic, Lewis George Gradon
