A device for regulating breathing gas delivered to a user, comprising a gas circuit comprising a main line having at least an upstream end intended to be connected to at least one gas source and a downstream end intended to be connected to at least one user station such as a mask, the main line comprising at least one electromechanical control valve configured to regulate the gas pressure between the upstream and the downstream, the circuit comprising a secondary line comprising an upstream end intended to be connected to at least one gas source and a downstream end intended to be connected to the same user station(s), the secondary line comprising at least one auxiliary member for regulating the gas flow, the device comprising a switching system configured to control the flow of gas between the upstream and the downstream of the circuit via the main line or via the secondary line, characterized in that the auxiliary member for regulating the secondary line is a pneumatic pressure regulator.

Regulating device, apparatus and method for generating breathing gas

The invention relates to an air-separation device comprising a generally cylindrical casing housing a filtration element including a bundle of hollow oblong fibers forming a membrane, the longitudinal axis of the fibers being parallel to the longitudinal axis (A) of the cylindrical casing, said casing comprising an air inlet at a first end and an outlet for purified gas at a second end. The device comprises a member for maintaining the fiber bundle in the casing, characterized in that the maintenance member comprises at least one spring member disposed inside the casing, said spring member being loaded between an end-stop formed by the casing and a longitudinal end of the fiber bundle in order to maintain the fiber bundle longitudinally in place while allowing it to dilate and contract.
