Patent number: 8646449Abstract: An anti-asphyxiation valve is disclosed, which is adapted for incorporation within a breathing circuit including a ventilator. The valve comprises one or more apertures for enabling passage of gas between the breathing circuit and the atmosphere, and a valve member deformable between an open configuration in which the one or more apertures are at least partially exposed and the passage of gas therethrough is enabled, and a closed configuration in which the valve member occludes the one or more apertures and the passage of gas therethrough is substantially prevented. The valve member is adapted such that the pressure within the breathing circuit at which the valve member deforms from the open configuration to the closed configuration is greater than the pressure within the breathing circuit at which the valve member deforms from the closed configuration to the open configuration.Type: GrantFiled: November 13, 2008Date of Patent: February 11, 2014Assignee: Intersurgical AGInventor: Richard Francis Bowsher

Publication number: 20130037026Abstract: A respiratory device for delivering gas to a patient comprises a gases passageway having proximal and distal ends, and a supplementary gas inlet in a side wall of the gases passageway. The supplementary gas inlet is adapted to direct gas along an interior surface of the gases passageway, such that the gas follows a generally helical path towards the distal end of the gases passageway.Type: ApplicationFiled: April 11, 2011Publication date: February 14, 2013Applicant: INTERSURGICAL AGInventor: Andrew Miller

Publication number: 20120227736Abstract: The invention concerns a respiratory ventilation connector for connection in the flow path between a patient interface and one or more fluid conduits in a respiratory ventilation system. The connector has first and second opposing body portions joined together so as to define a connector body having a first port, a second port and an internal passageway for fluid communication between said first and second ports. Each body portion has respective first and second spigot portions arranged in use to form an upstanding circumferential spigot formation about the first port. The spigot formation has an internal diameter which is greater than the diameter of the port so as to allow reception of a tubular fluid conduit within the spigot for communication with the first port in use.Type: ApplicationFiled: March 9, 2012Publication date: September 13, 2012Applicant: INTERSURGICAL AGInventor: Richard Bowsher

Patent number: 8210177Abstract: A valve for controlling the level of liquid within a chamber (10) is disclosed. The valve comprises a liquid inlet (30) and a primary float (40) that is movable in response to a change in the level of liquid (20) within the chamber (10) between an open configuration in which liquid (20) is able to flow through the liquid inlet (30) into the chamber (10) when the liquid (20) within the chamber (10) is below a predetermined acceptable level, and a closed configuration in which liquid (20) is prevented from flowing through the liquid inlet (30) into the chamber (10) when the liquid within the chamber (10) is at or above the predetermined acceptable level.Type: GrantFiled: August 10, 2007Date of Patent: July 3, 2012Assignee: Intersurgical AGInventors: Simon Robert Payne, Keethan Fernando

Patent number: 8181938Abstract: A humidification chamber (10) for use in a breathing circuit to humidify gases before inhalation is disclosed. The humidification chamber (10) is adapted to contain a volume of liquid (20), and comprises a gas inlet port (16), a gas outlet port (16) and a fluid inlet (30) for introducing liquid into the humidification chamber (10). The fluid inlet (30) is provided with a filter member (60) including a plurality of exit apertures for enabling flow of liquid through the filter member (60). The filter member (60) also defines a collection chamber (69) that is disposed below the exit apertures, in use, such that foreign objects in the liquid that are unable to pass through the exit apertures fall under the influence of gravity into the collection chamber (69).Type: GrantFiled: August 10, 2007Date of Patent: May 22, 2012Assignee: Intersurgical AGInventors: Simon Robert Payne, Keethan Fernando

Patent number: 8181940Abstract: A humidification chamber for use in a breathing circuit to humidify gases before inhalation is disclosed. The humidification chamber is adapted to contain a volume of liquid, and includes a gas inlet port, a gas outlet port, and a fluid inlet for introducing liquid into the humidification chamber. The fluid inlet is provided with a primary valve seat and a secondary valve seat. An actuating member engages the primary valve seat when liquid within the humidification chamber is at or above a predetermined acceptable level. The actuating member is deformable in response to an increase in liquid level above the predetermined acceptable level to a deformed configuration in engagement with the secondary valve to prevent liquid from flowing through the fluid inlet into the humidification chamber.Type: GrantFiled: December 7, 2011Date of Patent: May 22, 2012Assignee: Intersurgical AGInventors: Simon Robert Payne, Keethan Fernando
