Patent number: 8251066Abstract: A pressure sensitive valve device for use with respiratory equipment of the type that produces a pressurized flow of breathing gas. The valve device combines the exhalation and entrainment functions in one valve with a single air path. The valve device provides an exhaust valve function during normal operation and provides a less restricted access to the ambient atmosphere in the event of respiratory equipment malfunction. The valve device includes a valve element that moves between at least two positions. During normal operation, when the pressure generating system is generating a flow of gas, the valve element is in a “closed” or “exhaust valve” position. When in the exhaust valve position, the gas flow to the atmosphere is restricted without being completely blocked off. When the flow of gas is decreased or interrupted, the valve element moves to the “entrainment valve” or “open” position that allows a greater, i.e., less restricted flow, of gas between the user and the ambient atmosphere.Type: GrantFiled: December 20, 2005Date of Patent: August 28, 2012Assignee: Ric Investments, LLCInventors: Peter Chi Fai Ho, James DiPasquale, Elias G.

Publication number: 20120111331Abstract: A respiration appliance (10), system (40), and method (62, 72, 86) for supporting the airway of a subject (12) as the subject (12) breaths. The flow of gas from the lungs of the subject (12) during exhalation is leveraged to provide support to the airway. In particular, a body (14) that encloses one or more external orifices of the subject (12) provides a resistance differential between inhaled gas flows and exhaled gas flows that supports the subject's airway.Type: ApplicationFiled: December 9, 2009Publication date: May 10, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Erik Kurt Witt, Michael Edward Colbaugh, William Edwin Clegg, Douglas Mechlenburg
