Patent number: 12280214Abstract: 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: GrantFiled: February 18, 2021Date of Patent: April 22, 2025Assignee: Fisher & Paykel Healthcare LimitedInventors: Daniel John Smith, David Peter Baldwin

Patent number: 10286174Abstract: An expiratory limb for a breathing circuit includes an enclosing wall defining a flexible singular expiratory flow passage between an inlet and an outlet and bounding the flexible singular expiratory flow passage and ambient air. The expiratory limb includes one or more regions of the enclosing wall that made from a material that allows passage of water vapor without allowing passage of liquid water, thereby forming a water vapor flow path from the flexible singular expiratory flow passage to the ambient air through the material. The expiratory limb is configured to allow diffusion of water vapor along the flexible singular expiratory flow passage and dry the flow of expiratory gases between the inlet and the outlet.Type: GrantFiled: December 6, 2018Date of Patent: May 14, 2019Assignee: Fisher & Paykel Healthcare LimitedInventors: Daniel John Smith, Gavin Walsh Millar, Kevin Blake Powell, David Peter Baldwin
