Abstract

A check valve for a medical device comprising: an inlet duct (2); an outlet duct (1); a membrane (3); a compartment (4) for housing said disc membrane (3); a plurality of protuberances (9) inside the compartment (4) and configured to define a support for the disc membrane (3) when the valve is open, the disc membrane (3) being housed in a floating manner inside the compartment (4) so as to divide the compartment (4) into an inlet compartment (5) and an outlet compartment (6).
