Patent number: 8836521Abstract: One aspect of the invention is an apparatus including an alarm for alerting an operator to recharge a humidifier, wherein such alarm is generated other than through the use of a humidity sensor. In one embodiment the total work performed during heating and hydrating an insufflation gas is measured and an alarm generated when the total work performed exceeds a particular threshold. In another embodiment, a flow meter is used to measure the total flow of insufflation gas so that when the total flow of insufflation gas reaches a predetermined level an alarm is activated.Type: GrantFiled: July 24, 2012Date of Patent: September 16, 2014Assignee: Lexion Medical LLCInventors: Duane Lloyd, Douglas E. Ott

Publication number: 20080082084Abstract: One aspect of the invention is a method to vent gas from a body cavity during an endoscopic procedure. A body cavity is in fluid communication with an exhaust gas inlet of a vacuum break device. The vacuum break device has a chamber in fluid communication with both the inlet and an outlet. The chamber may comprise one or more openings in fluid communication with the atmosphere. A conduit in fluid communication with the exhaust gas outlet may be connected directly or indirectly to a suction source. The suction source may be activated.Type: ApplicationFiled: April 11, 2007Publication date: April 3, 2008Inventors: Keith Roberts, John Burban, Duane Lloyd

Publication number: 20050113797Abstract: A method and apparatus for treating gas for delivery into a body cavity, body space or body surface of an animal. The apparatus comprises a housing defining a chamber having an entry port and an exit port. One or more agents are released into the gas stream that flows through the chamber so that the gas stream carries the agent to the animal. Also shown, for use with, or without, the chamber, is an agent chamber adapted to be coupled to at least one structure defining at least one fluid flow path extending at least a portion of the distance between an insufflation device and the body cavity, body space or body surface.Type: ApplicationFiled: October 7, 2004Publication date: May 26, 2005Inventors: Douglas Ott, Patrick Spearman, Robert Gray, Duane Lloyd
