摘要

MEMBRANE UNIT, HOSTING OF A PRESSURE MEASURING UNIT AND PRESSURE MEASURING UNIT. The present invention relates to a membrane unit suitable for use in a housing of a pressure measuring unit, preferably for measuring pressure in an extracorporeal blood circuit comprising a flexible membrane and a retaining ring that is integrated with the outer membrane that the membrane and the retaining ring form a one-piece element, wherein the retaining ring has less flexibility than the membrane and in which the retaining ring comprises retaining elements for retaining the ring in the pressure measurement housing. The invention further relates to a housing as well as a pressure measuring unit.
