Abstract
A membrane unit configured for use in a housing of a pressure measuring unit, preferably for measuring pressure in an extra-corporal blood circuit, has a flexible membrane and a fixing ring which is integral with the membrane so that the membrane and the fixing ring form a one-piece element. The fixing ring has a lower flexibility than the membrane, and has fixing elements for fixing the fixing ring to the pressure measuring housing.
