摘要:
A gas routing module for insertion within a respiratory treatment apparatus is adapted to couple within a gas ports interface of a discrete compartment of a chassis of the respiratory treatment apparatus. The gas routing module comprises: - a plurality of gas routing channels adapted for gas communication with expired airflow; and - a gas ports interface, the gas ports interface including a plurality of gas ports in gas communication with the plurality of gas routing channels, wherein the gas ports interface comprises two or more of: (a) a port for expiratory pressure sensing, (b) a port for a PEEP air supply, and (c) a set of ports for expiratory flow sensing through one or more of the plurality of gas routing channels of the module.
摘要:
A respiratory device, such as a ventilator, for use in treating respiratory disorders and for preventing respiratory disorders. The respiratory device is configured to be powered from a range of different power sources including an internal battery, an external battery, AC power source or a DC power source. The device may be electrically connectable to a plurality of external batteries in a series and the power from each external battery is used sequentially along the series. A controller of the respiratory device is configured to detect the connection of the different power sources and control use of the different power sources using a power priority scheme. The controller may determine an estimate of the total available battery capacity from all the electrically connected batteries and display the total battery capacity on a user interface display of the device.
摘要:
A respiratory treatment apparatus configured to provide a flow of breathable gas to a patient, including a breathable air outlet (16), an outside air inlet (34), and a pneumatic block module (56), wherein the pneumatic block module includes: a volute assembly (108) including an inlet air passage, a mount for a blower and an outlet air passage; the blower being mounted in the mount such that an impeller of the blower is in a flow passage connecting the inlet air passage and the outlet air passage; a casing enclosing the volute assembly, wherein air passages within the casing connect air ports on the volute assembly, wherein the inlet air passage of the volute assembly is in fluid communication with the outside air inlet and the outlet air passage of the volute assembly is in fluid communication with the air outlet.
