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.

The invention relates to an aerosol delivery device (10) comprising an aerosol generator (3) for generating an aerosol in the aerosol delivery device (10), a sensor (5) configured to detect a use of the aerosol delivery device (10) for aerosol treatment, and a controller (7) configured to deactivate the aerosol generator (3) if no use of the aerosol delivery device (10) for aerosol treatment is detected by the sensor (5). Further, the invention relates to a method for operating an aerosol delivery device (10), comprising the steps of operating an aerosol generator (3) for generating an aerosol in the aerosol delivery device (10), detecting a use of the aerosol delivery device (10) for aerosol treatment by means of a sensor (5), and deactivating the aerosol generator (3) by means of a controller (7) if no use of the aerosol delivery device (10) for aerosol treatment is detected by the sensor (5).

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.

Disclosed is a headgear for an interface, comprising a rear loop, a lower side strap extending from the interface to the rear loop, and a pivotable connection. The pivotable connection is located between the lower side strap and the rear loop, or on the lower side strap. The pivotable connection is configured to allow for lateral movement of the lower side strap.

Disclosed is an NO delivery device for supplying an NO-containing gas, including an NO injection line, a flow rate measurement device and a valve device. The valve device is normally closed. An emergency line connected to the injection line includes an emergency solenoid valve, which is normally open, and a flow rate control device. An operating unit operates these elements. In the event of malfunction of the operating unit, the emergency solenoid valve passes to an open position, whilst the valve device passes to a closed position. The flow rate control device supplies the gas at a pre-fixed emergency flow rate of gas, determined on the basis of the gas flow rate measurements supplied by the flow rate measurement device during the normal functioning of the device prior to the malfunction. Gas supply installation including such an NO delivery device and a medical ventilator.

A method of ventilating a patient controls an actuator, in accordance with a prescribed value for a respiratory parameter, to compress an inflatable bag to cause air to flow out of an output valve of the bag. The respiratory parameter may include tidal volume, pressure, volume limit, peak pressure, I:E ratio, inspiratory time, and/or breathing rate of the air flowing through the output valve. The method also senses the pressure flowing through the output valve, and sends a pressure signal to the controller. Additionally, the method senses the flow rate through the output valve, and sends a flow rate signal to the controller. The method also adjusts the compression of the actuator as a function of the flow rate signal and/or the pressure signal to adjust the output tidal volume, pressure, volume limit, peak pressure, I:E ratio, inspiratory time, and/or breathing rate to be in accordance with the prescribed value.

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.

The present invention provides a method and apparatus for reducing condensation in a respiratory circuit during a delivery of humidifying agent into the respiratory circuit. A first amount of humidification agent to a first volume of gas is delivered to a patient respiratory circuit during a patient inhalation cycle or immediately after a patient exhalation cycle, and the humidification agent or the first volume of gas is heated. Condensation is removed from the respiratory circuit at least in part by providing, during a patient exhalation cycle or immediately after a patient inhalation cycle, a second amount of the humidification agent to a second volume of gas being delivered from the gas source to the patient respiratory circuit, the second amount of the humidification agent being significantly less than the first amount of the humidification agent.

Provided is an exacerbation prediction device equipped with a respiration sensing means of continuously sensing respiration data of a patient, a calculation means of calculating stable respiration data that are respiration data during a condition in which a respiratory rate is lowered and stable for a certain period of time from the sensed continuous respiration data of the patient, and a prediction means of predicting occurrence of an acute exacerbation in the patient in accordance with the stable respiration data calculated during a certain period of time.
