Abstract:
1. A gas regulating valve for a respiratory system comprising: a main path between an inlet and an outlet, and an evacuation path between the outlet and an evacuation orifice, wherein: the main path is provided with at least a non-return valve for preventing gas to circulate from the outlet to the inlet, and the evacuation path is provided with an obstructing membrane, the obstructing membrane defining a disc-shaped configuration, the obstructing membrane including a central deformable portion for at least partially closing the evacuation orifice when gas flows from the inlet, wherein the valve includes a central channel leading from a gas supply unit to the obstructing membrane, the central channel being sealed by the membrane at one end, the central channel being discrete from the main path; wherein the central deformable portion is configured to respond to pressure generated from the gas supply unit in the central channel so as to expand the membrane to block the evacuation path, and is configured to relax absent the pressure from the gas supply unit so as to open the evacuation orifice.
