Publication number: 20200114098Abstract: A respiratory treatment device includes a blower for providing flow of breathable gas to a patient and one or more accessory devices. The respiratory treatment device includes active power management to distribute power from a power source that does not have sufficient power to simultaneously power the blower and the accessory devices. The active power management prioritizes power to the blower and limits, based on current measurements of the blower and the accessory devices, the power supplied to the accessory devices to keep the sum of the power drawn at or below the capacity of the power supply. When additional power is available, due reduced power consumption of the blower, the power to one or more accessory devices is raised beyond a target in order to compensate for when power was not supplied to the one or more accessory devices.Type: ApplicationFiled: October 14, 2019Publication date: April 16, 2020Inventors: Andrew Roderick BATH, Rudi VOON, David CREUSOT, Dmitri Anatolievich DOUDKINE, Mike ZHU, Adam PANARELLO

Patent number: 10335571Abstract: 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: February 28, 2017Date of Patent: July 2, 2019Assignee: ResMed Paris SASInventors: Philippe Auguste Chalvignac, Arthur Kin-Wai Yee, David Creusot, Enrico Brambilla
