A patient interface, including a mask assembly and a headgear assembly, provides improved facial sealing and improved ease of use. The mask assembly includes an inflating or ballooning seal. The seal can be secured between two portions of a snap-fit exoskeleton. The headgear assembly connects to the mask assembly with flexible straps during course fitting and with more rigid straps following course fitting. The straps include holes that fit over a tapering post on the mask assembly.

A diagnostic device is disclosed for characterisation of particles from a patient's airways, such as a lung, when ventilated by a ventilator, and/or for control thereof, comprising a particle detecting unit configured to be connected to a conduit for passing expiration fluid from said patient, for obtaining data related to particles being exhaled from said patient's airways.

Aspects of the technology include methods and systems for performing remote adjustments to a ventilator with a remote device. A remote device may include an interactive display including a remote position indicator. The remote position indicator may be associated or correlated with a local ventilator position indicator. A selection and/or adjustment at the remote device (or an activation at the remote device) at the interactive display may result in a selection, adjustment, or activation at the ventilator. Information may be transmitted to the ventilator from the remote device to remotely adjust the ventilator. Additionally or alternatively, the remote device may additionally display a view of, or replicate, some or all portions of the ventilator display.

An aerosol medicament delivery adapter comprises a first conduit, second conduit and a diverter element. The first conduit encloses a flow path chamber and extends between an upstream first end and a downstream second end. The second conduit comprises an aerosol medicament delivery conduit that includes an upstream first end adapted to be fluidly coupled to a particle generator, and a downstream second end luidly coupled to the first conduit at a Y-junction proximate the upstream first end of the first conduit. The diverter element comprises a flow diverter chamber disposed within the first conduit or the second conduit. The cylindrical flow diverter chamber includes a transitional flow cross-section and a principal axis, extending between a first end and a second end thereof. The diverter element creates flow eddies for enhancing an entrainment of aerosol particles, delivered via the second conduit, within a pressurized gas flow along the flow path within the first conduit.

An infectious aerosol capture mask (IACM) includes a face tent coupled to a suction tube adapter. The face tent includes a proximal opening configured to be disposed over the mouth and nose of a patient. The face tent further includes a distal opening with a smaller diameter than the proximal opening. A coupler is configured to secure the suction tube adapter to the distal opening of the face tent. The suction tube adapter includes a suction port configured to be coupled to a suction tube for active capture of infectious aerosol and left unconnected for passive capture of infectious aerosol. A viral filter is disposed between the suction port and the face tent to capture infectious aerosols expelled by the patient. The IACM further includes one or more one-way valves that are configured to permit airflow into the face tent.

The present invention provides a respiratory mask comprising a nose cushion assembly. The nose cushion assembly comprises a base body and a buffering piece. The base body has a base intake portion, a base connection portion, and an air routing piece disposed at the inside of the base body and having a partitioning wall and a wall connection piece. The inside of the partitioning wall encloses an air intake zone. The wall connection piece is disposed outside the partitioning wall and connects with the base intake portion. Between the partitioning wall and the base intake portion there is defined an air outtake zone. The air intake zone is approximately at the center of the base intake portion. The buffering piece connects with the base connection portion and encloses a nose containing room, which in turn connects with the inside of the base body.

A conduit for communicating a flow of breathing gas from a pressure generating device to the airway of a patient. The conduit includes a first end which is structured to be coupled to the pressure generating device for receiving the flow of breathing gas and an opposite second end which is structured to be coupled to a patient interface device. The conduit further includes an active control element positioned at or near the second end; a first heating wire connected between the active control element and a first connection terminal positioned at or about the first end; and a second heating wire connected between the active control element and a second connection terminal positioned at or about the first end. Each of the first and second connection terminals are structured to be connected to a tube power supply.

A connection device and process connect a patient-side coupling unit to a source/sink of a gas including oxygen. The connection device includes a valve device with a first valve (40.1) and with a second valve (40.2). A source-side fluid guide unit establishes a fluid connection between the source or the sink and the valve device. A patient-side fluid guide unit establishes a fluid connection between the patient-side coupling unit and the valve device. The valves are connected in parallel and are arranged between the two fluid guide units. A gas flows from the source through the first and/or second valve to the patient-side coupling unit or through the first and/or second valves to the sink. A control pressure is set at each valve. As a result, the time course of the volume flow downstream of the valve device follows a predefined time course.

An apparatus for controlling the flow of oxygen to a patient comprises an outer housing extending between first and second ends having a passage therethrough. The housing composes a first portion extending from the first end towards the second end and a second portion extending from the second end towards the first end wherein the second portion is threadably rotatable relative to the first portion so as to longitudinally displaced relative to the first portion under rotation thereof so as to adjust at least a portion of the passage extending therethrough adjusting a flow capacity of the passage. The apparatus further comprises connectors at each of the first and second ends operable to connect to oxygen conduits to fluidically conned the oxygen conduits to the passage through the housing.
