Patent number: 8636002Abstract: A respiratory humidifier chamber for use with a breathing assistance apparatus is described. The chamber includes a water-tight vessel having an inlet for receiving gases from the breathing assistance apparatus, and an outlet through which heated humidified gases exit the vessel for delivery to a patient. The chamber has a partition which divides the chamber into upstream and downstream sub-chambers. The sub-chambers are separated by the partition except for an aperture which passes through the partition and allows gaseous communication between the sub-chambers. The downstream sub-chamber includes a heater base which heats a volume of water contained within it. The aperture is located above the volume of water. The upstream sub-chamber contains an internal heater which heats gases passing through it from the inlet to the aperture. At least part of the internal heater is located immediately adjacent the aperture.Type: GrantFiled: August 24, 2007Date of Patent: January 28, 2014Assignee: Fisher & Paykel Healthcare LimitedInventors: Alastair Edwin McAuley, Raymond Ka Yau Lo, David Fraser Wixey, Ian Douglas Makinson

Patent number: 7681571Abstract: Apparatus for delivery of humidified gases therapy includes a humidifier. A recorder records. An output interface allows for outputting of the recorded data. The recorder may also record data indicative of patient compliance with the humidified gases therapy. The apparatus may determine patient compliance from sensed delivered flow. Recorded humidity and compliance data retrieved from the apparatus are useful in methods for improving the efficacy of humidified gases therapy or diagnosing problems with the efficacy of humidified gases therapy.Type: GrantFiled: May 9, 2006Date of Patent: March 23, 2010Assignee: Fisher & Paykel Healthcare LimitedInventors: Ian Douglas Makinson, Alex Young, David Alan Bond

Patent number: 7478635Abstract: The present invention may include an integral, separable or separate humidifier (100) which may be selectively configured to an inoperative or operative state. The switch over is dependent on the user or the seller having access to an actuation tool to activate the humidifier. The Continuous Positive Airway Pressure (CPAP) device is initially available for use as a standalone CPAP (100). The heater plate being isolated by a covering shroud (102), the shroud (102) also forms a connection port for the CPAP blower outlet (104). The heated humidification hardware being disabled by the absence of the activation tool. Upgrade to a CPAP device including heated humidification is completed by the installation of the actuation tool. Removal of the heater plate isolating shroud and/or installing the actuation tool enables the software controlled heated humidification hardware for heated humidifier operation. Other upgrades to functionality are also disclosed.Type: GrantFiled: October 29, 2003Date of Patent: January 20, 2009Assignee: Fisher & Paykel Healthcare LimitedInventors: David Fraser Wixey, Ian Douglas Makinson

Publication number: 20080190427Abstract: A breathing assistance apparatus and method of controlling a breathing assistance apparatus is disclosed. Particularly, the breathing assistance apparatus is controlled such that it has a drying cycle to enable drying of the tubing that supplies gases to a user and prevent the harbouring of pathogens within the tube. The drying cycle is preferably operated automatically by internal controllers in the apparatus. However, it may be manually activated by pressing a button on the apparatus. The drying cycle is preferably activated at the end of a user's treatment session.Type: ApplicationFiled: May 26, 2006Publication date: August 14, 2008Inventors: Matthew Jon Payton, Kevin Peter O'Donnell, Christopher Simon James Quill, Ian Douglas Makinson, Emily Joy Drake, Craig Karl White, Virginia Louise Glover
