The exit can comprise a connective part which may be configured to be coupled to one or more objects such as clothing, strings, necklaces and chains, bracelets, headbands and hair accessories, and the like.

A device which can trap and remove a condensate derived from a fluid which is exhaled by a patient connected to a ventilation circuit comprises a body (2) connected by means of a first duct (8) to a ventilation apparatus of this circuit, and by means of a second duct (11) to tubing connected to the patient, said body (2) having a first and a second portion (3, 4) connected to one another, the second portion (4) being able to collect said condensate from the exhaled fluid, said second portion comprising a bottom wall (13) from which there rises a lateral wall (14) delimiting a cavity (10) for collection of said condensate; an absorbent element (23) is provided which can absorb this condensate collected in the second portion (4) of this body (2), said absorbent element (23) being removable from said body (2) such as to permit replacement thereof.

A CPAP system for respiratory therapy includes an RPT device configured to supply a flow of gas at a therapeutic pressure, a patient interface, an air delivery conduit configured to pass the flow of gas from the RPT device to the patient interface, and a vent assembly configured to provide a vent flow of gas to discharge gas exhaled by the patient from a pressurized volume to ambient. The vent assembly includes a base including at least one first orifice to allow gas to be discharged along a primary vent flow path and at least one second orifice to allow gas to be discharged along a secondary vent flow path, a diffusing member provided to the base, and a membrane provided to the base. The membrane is configured to apportion the vent flow of gas along the primary vent flow path and the secondary vent flow path throughout respiratory therapy.

Systems and methods for producing oxygen enriched air using vacuum pressure swing adsorption (VPSA) are disclosed. In one implementation, an oxygen concentrator includes a canister system having at least one canister, a pumping system having at least one motor-controlled pump, a set of valves pneumatically coupling the canister system and the pumping system, and a controller. The canister is configured to receive a gas separation adsorbent. The controller is configured to control operation of the pumping system and the set of valves to: selectively pneumatically couple the motor-controlled pump and the canister so as to pressurize the canister and selectively pneumatically couple the motor-controlled pump and the canister so as to evacuate the canister.

An ambulatory assist ventilation (AA V) apparatus and system are disclosed for the delivery of a respiratory gas to assist the spontaneous breathing effort of a patient with a breathing disorder. The AA V system includes a compressed respiratory gas source, a respiratory assist device for controlling respiratory gas flow to the patient, a patient circuit tubing and a low profile nasal interface device, which does not have a dead space or hollow area where CO2 can collect, for delivering the respiratory gas to the patient, wherein the nasal interface device is fluidly connected to the respiratory assist device via tubing for receiving the respiratory gas therefrom.

A respiratory treatment device for the combined administration of respiratory muscle training (“RMT”) and oscillating positive expiratory pressure (“OPEP”) therapy, and administration of RMT using pressure threshold resistors and flow resistors with respiratory treatment devices, such as OPEP devices.

An apparatus for oxygenation and/or CO2 clearance of a patient. The apparatus comprising: a flow source or a connection for a flow source for providing a gas flow, a gas flow modulator, a controller to control the gas flow. The controller is operable to: receive input relating to heart activity and/or trachea gas flow of the patient, and control the gas flow modulator to provide a varying gas flow with at least two oscillating components. One oscillating component has a frequency based on the heart activity and/or trachea flow of the patient. One oscillating component has a frequency to: promote bulk gas flow movement, or promote mixing.

A lung simulator for partial simulation of functions of a lung, comprising at least one gas loop which is connected to a ventilator which is configured to convey a breathing gas into and/or out of the gas loop at least temporarily. The lung simulator comprises at least one device for setting the O2 concentration of the breathing gas in the gas loop, at least one device for setting the CO2 concentration of the breathing gas in the gas loop and at least one device for simulating a mechanical lung movement.

An arrangement for exhausting gases from a cavity of a patient interface to an ambient environment, patient interface for use in providing a flow of treatment gas to the airway of a patient. The arrangement includes a body member that forms a portion of the patient interface between the cavity and the ambient environment. The body member includes: a number of inlets defined in a first side of the body member for receiving gases from the cavity; a number of outlets defined in a second side of the body member opposite the first side for provide for the exit of gases from the patient interface to the surrounding environment; and a number of high-drag passages defined in the body member extending laterally between an inlet of the number of inlets and an outlet of the number of outlets.

A high flow nasal therapy system (1) has a gas supply (2), a nebulizer (12), and a nasal interface (7). There are two branches (11, 10) and a valve (6) linked with the controller, the branches including a first branch (11) for delivery of aerosol and a second branch (10) for delivery of non-aerosolized gas. The controller controls delivery into the branches (11, 10), in which flow is unidirectional in the first and second branches, from the gas supply towards the nasal interface. The first branch (11) includes the nebulizer (12) and a line configured to store a bolus of aerosol during flow through the second branch (10). The valve (6) comprises a Y-junction between the gas inlet on one side and the branches on the other side.
