The invention relates to a breathing apparatus, which comprises a respiratory gas source, a control unit and a device for connection to a tube. The control unit of the apparatus is connected to at least one sensor for recording a measurement value, the control unit comprising a pressure generator for setting at least two pressure levels generated by the respiratory gas source and a memory for measurement values, and the sensor being configured for measuring a flow and being coupled to an analyzer which determines the volume. The apparatus operates as specified in the claims.

An oxygen concentrator (100) apparatus and a method thereof implement operations control to efficiently release oxygen enriched gas to reduce potential waste. The control methodology may include generating a profile such as a minimum inhalation flow profile of the user. The profile may be based on a size parameter of the user. The method may determine one or more control parameters characterizing a bolus of oxygen enriched gas based on the generated flow profile. The control methodology may then generate a bolus release control signal, such as for a supply valve, according to the determined one or more control parameters. The oxygen concentrator may then, with the control signal, release and deliver a bolus of oxygen enriched gas for a user such as for reducing waste.

The present invention relates to a respiratory therapy device (1) for producing a breathable air stream for carrying out respiratory therapy, comprising a housing system (2) for housing device components. The housing system (2) comprises two mounting surfaces (12, 22) so that the respiratory therapy device (1) can be mounted and operated as intended in two mounting positions (3, 4). The invention also relates to a coupling system (200) for coupling at least two respiratory therapy devices (1), as well as to an apparatus comprising said coupling system (200), and to a coupling system (200) for receiving a respiratory therapy device (1).

The invention relates to a respiratory assistance apparatus (10) comprising a rigid internal casing (1) comprising a motor compartment (3) within which a motorized micro-blower (2) is arranged. The casing (1) is formed from a first and a second half-casing (1a, 1b) which are rigidly connected to each other in a leaktight manner.

An isolation hood for respiratory treatment is disclosed. The isolation hood may include a head enclosure defining an interior volume configured to receive the head of a patient, and a neck seal configured to couple the head enclosure to a neck of the patient. The isolation hood may include an inlet port configured to be coupled to a distal end of a treatment source tube and to a first end of a treatment delivery tube, and an outlet port configured to be coupled to an inline particle filter configured to permit air to flow through the head enclosure. The neck seal and the inline particle filter are each configured to prevent viral/bacterial aerosolization outside the hood. The inlet and outlet ports may be attached to respiratory tubing and non-invasive ventilatory equipment to permit aerosol-generating procedures within the hood while preventing viral/bacterial aerosolization outside the hood.

The present disclosure provides systems and methods for nitric oxide (NO) generation and/or delivery. In some aspects, a nitric oxide generation system comprises a plasma chamber configured to ionize a reactant gas including nitrogen and oxygen to form a product gas that includes NO, a scrubber downstream from the plasma chamber and having a volume at least partially containing NO.sub.2 scrubbing material, and a flow controller downstream of the scrubber configured to control the flow of product gas from the scrubber to a delivery device. A pump is configured to convey product gas from the plasma chamber into the scrubber and is configured to pressurize the product gas in the scrubber when the flow controller is positioned to restrict the flow of product gas from the scrubber. The pressurized product gas accumulates within the scrubber and is at least partially scrubbed of NO.sub.2 prior to passage through the flow controller.

A CPAP device for delivering pressurized, humidified breathable gas for a patient includes a flow generator configured to pressurize a flow of breathable gas. The flow generator includes an air outlet and a removable water container configured to humidify the pressurized breathable gas received from the flow generator. The water container includes an air inlet and an air outlet. The CPAP device further includes a first elastomeric face seal configured to sealingly abut against a substantially flat portion of the water container surrounding the water container air inlet, the first elastomeric face seal being located at an intermediate position between the flow generator air outlet and the water container air inlet when the water container is placed into position to pneumatically communicate with the flow generator. In addition, the CPAP device includes a second elastomeric face seal, a portion of which is configured to sealingly abut against a substantially flat external surface portion of the water container surrounding the water container air outlet.

A combination positive airway pressure (PAP) or continuous positive airway pressure (CPAP) and resuscitation system and related methods. The systems can be well-suited for use in providing CPAP therapy for a neonate or infant patient, with the ability to also provide resuscitation therapy at a peak inspiratory pressure (PIP) as needed or desired without switching to another system or switching the patient interface. The system can include an expiratory pressure device capable of regulating a positive end expiration pressure (PEEP) of the system, which preferably can also induce pressure oscillations relative to a mean PEEP.

A gas valve (11) for ventilation which comprises a main body (12) having a first gas chamber (13), a second gas chamber (15) and at least an inlet duct (14) for supplying a gas to the first gas chamber (13). The gas valve (11) further comprises a proportional valve (24) for temporally sealing the first gas chamber (13) from the second gas chamber (15). The second gas chamber (15) comprises at least a second passage opening (22) for releasing the gas from the second gas chamber (15) and the second gas chamber (15) comprises a port (30) for connecting a pressure measurement apparatus for measuring the gas pressure in the second gas chamber (15). A circuit with a ventilation limb which comprises a gas valve (11) and a method for determining a releasing gas flow of a gas valve are also disclosed.

A portable oxygen generating system is provided that comprises a reaction chamber, a feed system for providing and controlling hydrogen peroxide solution to the reaction chamber, and a cooling/condensing system for cooling the hot oxygen and water vapor leaving the reactor and condensing and removing water. The portable chemical oxygen generation system produces humidified, breathable oxygen, that is substantially free of hydrogen peroxide and other contaminants, at a controlled flow and temperature over an extended period of time.
