Patent number: 11420008Abstract: A vent system for use during respiratory therapy with a flow of pressurized gas may provide a continuous vent flow of gas. The vent system may include a vent housing having an outer wall; an inner wall, the inner wall defining an inlet for the flow of gas; and a base positioned between the outer wall and the inner wall, the base having at least one first orifice and at least one second orifice. The vent system may include a membrane, the membrane being shaped and dimensioned such that the membrane does not cover the at least one first orifice to allow the vent flow through the at least one first orifice, and the membrane being shaped and dimensioned such that in a first position the membrane is positioned over the at least one second orifice to allow the vent flow through the at least one second orifice.Type: GrantFiled: September 21, 2017Date of Patent: August 23, 2022Assignee: ResMed Pty LtdInventors: Muditha Pradeep Dantanarayana, Charles Harry Finch, Justin John Formica, Richard Llewelyn Jones, Joseph Samuel Ormrod, Jamie Graeme Wehbeh, Chia Ik Tan
