Publication number: 20200001039Abstract: In some embodiments, a humidification system includes a heater base having a heater plate, a humidification chamber, and circuit. The circuit can include various conduits, including an inspiratory conduit, expiratory conduit, Y-piece, patient conduit, and/or dry conduit. In use, the chamber contains a quantity of liquid. The heater base heats the heater plate, which in turn heats the liquid to a temperature that causes at least some of the liquid to become vapor, thereby humidifying the gases within the chamber. The gas is delivered to the patient via the inspiratory conduit. Various features can help control the system and ensure the patient receives gases having the desired conditions. These features can be used individually or in various combinations and subcombinations both in existing humidification systems and improved systems for respiratory humidification, laparoscopy, and other purposes.Type: ApplicationFiled: September 11, 2019Publication date: January 2, 2020Inventors: Dexter Chi Lun Cheung, Matthew Jon Payton, Michael Barraclough, Michael John Andresen, Kieran Michael Orchard, Philip James Edgeworth, Peter Kenneth Graham, Anthony James Newland, Daniel John Smith, Timothy James Beresford Sharp, Elmo Benson Stoks, Jonathan Mark Church, Andre van Schalkwyk

Publication number: 20190307978Abstract: Various control methods can indirectly determine incorrect connections between components in a respiratory therapy system. For example, errors in the connections can occur between a patient interface, a humidifier and/or a gases source. The methods can indirectly detect if a reverse flow condition exists or other error conditions. A reverse flow condition can occur when gases flows in a direction different from an intended direction of flow. The detection of the reverse flow condition can be indicative of likely errors in connections between the humidifier, patient interface and/or gases source.Type: ApplicationFiled: October 11, 2017Publication date: October 10, 2019Inventors: Po-Yen Liu, Ivan Chih-Fan Teng, Peter Alan Seekup, Daniel John Smith, Ho Shing Lo

Publication number: 20190275265Abstract: 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: March 28, 2019Publication date: September 12, 2019Inventors: Michael Joseph Blackhurst, Nina Caroline Heatley, Daniel John Smith, Hussein Kadhum

Publication number: 20190269872Abstract: A patient interface, including a mask assembly and a headgear assembly, provides improved facial sealing and improved ease of use. The mask assembly includes an inflating or ballooning seal. The seal can be secured between two portions of a snap-fit exoskeleton. The headgear assembly connects to the mask assembly with flexible straps during course fitting and with more rigid straps following course fitting. The straps include holes that fit over a tapering post on the mask assembly.Type: ApplicationFiled: April 5, 2019Publication date: September 5, 2019Inventors: Daniel John Smith, Brett John Huddart, Matthew James Adams, Nicholas Alexander Hobson, Timothy James Beresford Sharp, Troy Barsten, Gregory James Olsen, Matthew Roger Stephenson, Roheet Patel

Publication number: 20190201649Abstract: 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: March 7, 2019Publication date: July 4, 2019Inventors: 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
