Patent number: 8709187Abstract: A method of continuously forming heated conduit includes performing a tape for winding onto a spiral pipeline former. At least one conductor is positioned adjacent to the centerline of and parallel with a thin polymer ribbon. The ribbon is folded in half to encapsulate the conductors. The folded ribbon is thermally welded to itself. The folded, welded, ribbon is passed through a creaser, which forms a crease midway across the folded ribbon. The creased pre-formed ribbon is formed into a conduit in a continuous process on a spiral pipeline former.Type: GrantFiled: November 13, 2008Date of Patent: April 29, 2014Assignee: Fisher & Paykel Healthcare LimitedInventors: Daniel John Smith, Nathan Lee Gray, Luke Jeremy Gallagher, Kieran James Hatcher, Kristopher Poh Ming Laurent

Publication number: 20130072862Abstract: This invention relates to apparatus used to alter the temperature and humidity of gases. The apparatus of the present invention comprises an insufflator, humidifier and transportation means connected to delivery means to deliver humidified and heated gases to a body cavity prior to and during a medical procedure. In one form of the present invention the insufflator and humidifier are contained in the one housing, while in another form the humidifier is located proximal and external to the insufflator. The transportation means that delivers the humidified gases to the body cavity comprises a flexible tubing having located within, throughout or around it heating means. The heating means may be a heat conductive wire, a ribbon of PTC material, or a conducting wire extruded into the walls of tubing, where the tubing may be made from a PTC material or flexible plastics.Type: ApplicationFiled: June 22, 2012Publication date: March 21, 2013Applicant: FISHER & PAYKEL HEALTHCARE LIMITEDInventors: Michael Joseph Blackhurst, Nina Caroline Batty, Daniel John Smith, Hussein Kadhum

Publication number: 20120174924Abstract: A conduit for a breathing circuit includes a heater associated, at least in part, with a hydrophilic layer. The purpose of the heater is to evaporate any condensed liquid collecting in the conduit, which is first sucked up by the hydrophilic layer. The heated wick reduces the risk of collected water being passed to the patient and causing choking fits or discomfit. It is preferred that the heated wick lies freely in the conduit to settle at low points in the conduit where condensation may collect.Type: ApplicationFiled: October 12, 2011Publication date: July 12, 2012Applicant: FISHER & PAYKEL HEALTHCARE LIMITEDInventors: Daniel John Smith, David Peter Baldwin

Patent number: 7958891Abstract: A method of conveying humid breathing gases from a patient through a breathable breathing tube. The breathing tube includes a heater associated, at least in part, with a portion of hydrophilic material. The purpose of the heater is to evaporate any condensed liquid collecting in the conduit, which is first sucked up by the hydrophilic material. The heated wick reduces the risk of collected water being passed to the patient and causing choking fits or discomfit. It is preferred that the heated wick lies freely in the conduit to settle at low points in the conduit where condensation may collect.Type: GrantFiled: May 6, 2009Date of Patent: June 14, 2011Assignee: Fisher & Paykel Healthcare LimitedInventors: Daniel John Smith, David Peter Baldwin
