A respiratory treatment apparatus configured to provide a flow of breathable gas to a patient, including a breathable air outlet, an outside air inlet, and an pneumatic block module, wherein the pneumatic block module includes: a volute assembly 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.

Ventilator apparatus and method

A blower includes a housing including a proximal opening and a distal opening that are co-axially aligned, a stator component provided to the housing, an impeller positioned between the proximal opening of the housing and the stator component, and a motor adapted to drive the impeller. The impeller includes a plurality of impeller blades. The stator component includes a plurality of air directing grooves along its exterior surface. The leading edge of the air directing grooves extend tangentially outwards from the outer tips of the impeller blades and are configured to collect the air exiting the impeller blades and direct it from a generally tangential direction to a generally radial direction by dividing the air from the impeller and directing the air along a curved path towards the distal opening so that airflow becomes substantially laminar.

Single stage, axial symmetric blower and portable ventilator

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.

Breathable gas inlet control device for respiratory treatment apparatus

A breathing assistance device includes a gas regulating valve (). The gas regulating valve is operated by a linear actuator (). The linear actuator may include a movable member that moves an obstruction member between an open position and a closed position. The linear actuator is isolated from a gas flow path through the valve.

Breathing assistance device with linear actuated gas regulating valve

A blower includes a housing including a proximal opening and a distal opening that are co-axially aligned, a stator component) provided to the housing, an impeller positioned between the proximal opening of the housing and the stator component, and a motor adapted to drive the impeller. The impeller includes a plurality of impeller blades. The stator component includes a plurality of air directing grooves along its exterior surface. The leading edge of the air directing grooves extend tangentially outwards from the outer tips of the impeller blades and are configured to collect the air exiting the impeller blades and direct it from a generally tangential direction to a generally radial direction by dividing the air from the impeller and directing the air along a curved path towards the distal opening so that airflow becomes substantially laminar.

The invention relates to a gas regulating valve () for a respiratory system comprising:&#x2014;a main path between an inlet () and an outlet (), and&#x2014;an evacuation path between the outlet () and an evacuation orifice (), characterised in that:&#x2014;the main path is provided with at least a non-return valve for preventing gas to circulate from the outlet () to the inlet (), and&#x2014;the evacuation path is provided with an obstructing membrane () arranged and designed for being deformed by gas from the inlet () to partially or fully obstruct the evacuation path. The invention also relates to a mask integrating such gas regulating valve, and to a respiratory system also comprising such gas regulating valve.

Passive gas regulating valve for a respiratory system

A blower () includes a housing () including a proximal opening () and a distal opening () that are co-axially aligned, a stator component () provided to the housing, an impeller () positioned between the proximal opening of the housing and the stator component, and a motor () adapted to drive the impeller. The impeller includes a plurality of impeller blades. The stator component includes a plurality of air directing grooves () along its exterior surface. The leading edge of the air directing grooves extend tangentially outwards from the outer tips of the impeller blades and are configured to collect the air exiting the impeller blades and direct it from a generally tangential direction to a generally radial direction by dividing the air from the impeller and directing the air along a curved path towards the distal opening so that airflow becomes substantially laminar.
