A blower of a CPAP device is housed inside a main body case of a CPAP device. The blower is roughly divided into a fan unit housing a fan therein, and a delivery tube, through which air sent from the fan passes. In the main body case, a first support member, a second support member, and a third support member are interposed between the main body case and the fan unit to support the fan unit. When viewed from a rotation axis of the fan, the first support member and the second support member are disposed to pinch the blower on the side of a connection point between the fan unit and the delivery tube relative to the rotation axis, and the third support member is located on the opposite side to the connection point between the fan unit and the delivery tube relative to the rotation axis.

A heated conduit is configured to connect to and receive pressurized breathable gas from a respiratory unit. The heated conduit includes a first cuff that includes an air inlet portion and an electrical connector portion that is adjacent the air inlet portion and comprises three electrical terminals that are configured to engage a respiratory unit electrical connector. The heated conduit also includes a second cuff comprising an air outlet and a flexible tube portion with a first end connected to the first cuff, a second end connected to the second cuff, and a spiral rib structure wrapped around a central lumen. A grouping of wires is supported within the spiral rib structure of the flexible tube portion and include a pair of heating wires and a signal wire. A sensing device extends into the gas flow path from an interior surface of the second cuff and is configured to output a signal indicative of the condition inside the heated conduit.

A stand-alone continuous positive airways pressure, CPAP, apparatus having a face-mask and a connected electro-mechanical device to supply air to the face-mask is disclosed. The electro-mechanical device includes a pneumatic channel for flowing air to be delivered to the face mask and a control unit for managing the air pressure of the air inside the pneumatic channel. The CPAP apparatus includes a turbine fan, located in the electro-mechanical device housing, connected to the control unit for pressurizing atmospheric air. The pneumatic channel includes an inlet portion located upstream of the turbine fan to receive atmospheric air, and an outlet portion located downstream of the turbine fan to deliver the pressurized air to the face-mask through an outlet opening. The pneumatic channel also longitudinally extends from the inlet portion to the outlet portion.

A foam inhalation device (874) for dispensing a foam to be inhaled by a user. The inhalation device (874) comprises a foam-generating component for generating the foam, an outlet (882) for dispensing the foam to the user, and a fluid flow path which fluidly communicates the foam-generating component with the outlet (882). The foam is generatable by the foam-generating component and flows to the outlet (882) via the fluid flow path to be inhaled by the user.

An absorption arrangement (100) includes a CO2 absorber (4) and a water trap (2). Such an absorption arrangement (100) is used with a process for filtering carbon dioxide from a gas mixture by absorption. The gas mixture flows from a source through the absorption arrangement (100) to a sink in the following way: through a supply fluid guide unit (3), through a lower deflecting fluid guide unit (9), through the CO2 absorber (4), through an upper deflecting fluid guide unit (6), through a connecting fluid guide unit (33), through the water trap (2) and through a discharge fluid guide unit (34). The gas mixture flows vertically or obliquely upward through the CO2 absorber (4) and vertically or obliquely downward through the connecting fluid guide unit (33) to the water trap (2).

A ventilation system includes an electrochemical filter for depleting alkyl phenols, especially 2,6-diisopropyl phenol, in breathing gas. A method uses the filter for removing alkyl phenols, especially 2,6-diisopropyl phenol, from breathing gas.

A respiratory assistance apparatus includes a conduit connecting a flow generator and an outlet. The conduit includes a venture formation. The apparatus further includes an oxygen inlet in fluid communication or selective fluid communication with an oxygen outlet. The oxygen outlet is directed into the conduit and toward a mouth of the venture formation. The flow generator provides a flow path for air to enter the conduit when the flow generator is not operating.

In accordance with this disclosure, we provide a medical conduit configured to deliver breathable gases in a respiratory therapy system. The medical conduit comprises: i. a first conduit end connector configured to be connected to a user interface; ii. a second conduit end connector configured to be connected to a heated inspiratory conduit; iii. the medical conduit further comprising at least one portion intermediate the first and second conduit end connectors made from a breathable material; iv. the medical conduit being configured to connect the user interface to the heated inspiratory conduit; v. the medical conduit being configured, when connected to the user interface and the heated inspiratory conduit, to be located in an incubator; wherein vi. the medical conduit is unheated. Such a medical conduit can be used in a respiratory therapy system, which comprises an incubator, with the medical conduit inside the incubator.

An inline muffler for use with a positive airway pressure (PAP) apparatus. The muffler may provide an expansion chamber with baffles that capture acoustic energy using, for instance, a disruptive gas flow path to effectively reduce downstream noise associated with a flow of pressurized gas produced by the PAP apparatus. In some embodiments, the muffler is constructed of two mostly identical halves with baffle segments being integrally formed therewith.

A tub is configured to contain a supply of water and is configured to be inserted into a chamber of a humidifier. The tub includes a tub base configured to contain the supply of water. The tub also includes a tub lid and a flow plate provided between the tub base and the tub lid. The flow plate includes a water level indicator configured to indicate a level of the supply of water in the tub base. In addition, the water level indicator includes a generally rectangular portion and a generally triangular portion.
