Patent number: 9616189Abstract: A breathing assistance device may include a turbine for generating flow of pressurized respiratory gas, a duct for carrying pressurized gas to a patient, and a mechanism to control gas pressure capable of elaborating a pressure setting for the turbine. The turbine is connected to a speed sensor for acquiring the rotation speed of a rotating element of the turbine. A mechanism controls a calculation in order to elaborate a pressure setting and to send the pressure setting to the turbine. A method regulates the pressure of a respiratory gas delivered by a turbine to a patient. The method involves elaborating a pressure setting for the turbine. The pressure setting is elaborated using a signal representative of the rotation speed of a rotating element of the turbine.Type: GrantFiled: August 16, 2012Date of Patent: April 11, 2017Assignee: ResMed Paris SASInventor: Philippe Chalvignac

Patent number: 9616192Abstract: A breathable gas inlet control device permits flow regulation at the inlet of a flow generator for a respiratory treatment apparatus such as a ventilator or continuous positive airway pressure device. The device may implement a variable inlet aperture size based on flow conditions. In one embodiment, an inlet flow seal opens or closes the inlet to a blower in accordance with changes in pressure within a seal activation chamber near the seal. The seal may be formed by a flexible membrane. A controller selectively changes the pressure of the seal activation chamber by controlling a set of one or more flow control valves to selectively stop forward flow, prevent back flow or lock open the seal to permit either back flow or forward flow. The controller may set the flow control valves as a function of detected respiratory conditions based on data from pressure and/or flow sensors.Type: GrantFiled: March 25, 2011Date of Patent: April 11, 2017Assignee: ResMed Paris SASInventors: Philippe Auguste Chalvignac, Arthur Kin-Wai Yee, David Creusot, Enrico Brambilla
