A respiratory therapy system can have a flow generator adapted to provide gases to a patient. A gas passageway can be located in-line with the flow generator. The gas passageway can have a first portion adapted to receive a first gas and a second portion adapted to receive a second gas. The gas passageway can have a static mixer downstream of the first and second portions.

A blower includes a rotor, a motor adapted to drive the rotor, at least one bearing to rotatably support the rotor, a stationary component, and a bearing sleeve provided to the stationary component. The bearing sleeve is structured and arranged to support and retain the bearing to the stationary component. The bearing sleeve comprises an elastomeric material, and the bearing sleeve comprises one or more bumps or ribs configured to engage along an outer ace of the bearing.

A respiratory therapy device comprising at least one fan unit for generating a respiratory airflow for carrying out respiratory therapy. The fan unit comprises a housing and at least one fan wheel rotatably mounted in the housing. Respiratory air is transported through a channel formed inside the housing, which housing comprises at least one structural element, which reduces the sound emission.

A mechanical ventilation device comprising at least one electronic controller configured to receive imaging data and transpulmonary pressure data associated with a lung of a patient; perform deformable image registration of the inhalation image and the exhalation image to produce a relative compliance or elasticity map of the lungs; convert the relative compliance or elasticity map of the lungs to a quantitative compliance or elasticity map of the lungs based on the inhale transpulmonary pressure and the exhale transpulmonary pressure; and display the information relating to or derived from the quantitative compliance or elasticity map on a display device.

A steam inhaler includes a steam chamber housing having mounted therein a heater assembly. The steam chamber housing defines a steam chamber adapted to receive water. A fitting mounted to the steam chamber housing has a steam conduit section extended toward an exterior vent opening, a nozzle conduit section extended from the steam conduit, and a fresh air conduit section extended from the steam conduit section at a location downstream of the nozzle conduit section. The fitting is configured such that steam flows freely from the steam chamber, through the steam conduit section toward the exterior vent opening, a suction provided at the nozzle redirects at least a portion of the steam into the nozzle conduit section toward a mask, and the fresh air conduit directs fresh air into the steam conduit section to reduce a temperature of the steam exiting the exterior vent opening.

A ventilator includes a ventilation body, the ventilation body includes a ventilation cavity and an air inlet end and an air outlet end communicating with the ventilation cavity, the ventilation body further includes an annular shell configured to form the ventilation cavity, the annular shell is formed with an annular cavity inside, an air inlet and an air outlet communicating with the annular cavity are disposed on the annular shell, the air outlet is communicated with the annular cavity and the ventilation cavity, the air outlet has a slit shape extending along a circumferential direction of the annular shell and is disposed to be capable to guide gas flows out towards the air outlet end. The ventilator may greatly increase the ventilation volume and the gas pressure, by using the ventilation body as mentioned above.

A liquid ventilation system includes a reservoir holding a perfluorochemical (“PFC”) fluid, and a suction pump connected to the reservoir to reduce pressure within the reservoir. A sensor is configured to measure an intra-lung pressure. An appliance is configured to be disposed within a patient. The appliance carries an injector to supply the PFC fluid through the appliance. An extraction valve is disposed on an extraction line between the appliance and the reservoir. The extraction valve is arrangeable between a first position enabling fluid communication from the appliance to the reservoir and a second position disabling fluid communication from the appliance to the reservoir.

An apparatus is provided to change the absolute humidity of a flow of air for delivery to an entrance of the airways of a patient, the change being compared to the absolute humidity of ambient air. The apparatus has a reservoir configured to hold a volume of liquid. A heating element creates vapour from the liquid. A chamber is provided to mix the flow of air with the vapour. The apparatus has a body having a first wall structure with a chamber inlet port. A closure element having an air inlet port for pneumatically connecting to a source of the flow of air is secured to the body to provide a sealed gas flow path between the air inlet port and the chamber inlet port, and a liquid trap in the gas flow path.

A modularized respiratory treatment apparatus provides various respiratory pressure treatments. The apparatus may be formed by discrete connectable modules such as a flow generator module, alarm module and/or humidifier module. Each module may include its own external casing or housing to independently retain or enclose the respective components that serve the function of the module. Different modules may be adapted with different components and functionalities and may be readily coupled using standardized gas and electrical connection configurations that have flow and communication paths that extend through the modules. When coupled, operation of the respiratory treatment apparatus may be controlled by detection of different modules, such as the alarm module that generates visual and/or audible alarms based on detected conditions, so as to selectively enable or disable different respiratory treatments. The discrete modules of the medical treatment apparatus may include tamper resistant locking mechanisms to impede unauthorized separation of some modules.

In the present disclosure, air passing through the inside of a humidifier is readily humidified. The humidifier includes a water chamber having a first circulation opening and a second circulation opening for allowing air to circulate. An outlet baffle that covers at least part of the second circulation opening from below is provided on an inner surface of a top cover of the water chamber. A third circulation opening is formed by the outlet baffle. The direction in which the third circulation opening opens intersects the direction in which the first circulation opening opens. A baffle protrudes from the inner surface of the top cover. The baffle is located on a straight path between the third circulation opening and the first circulation opening and extends in a direction that intersects the straight path.
