Beschreibung
Zusammenfassung:	The present invention relates to a membrane unit adapted for use in a housing of a pressure measuring unit preferably for measuring pressure in an extra-corporal blood circuit comprising 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, wherein the fixing ring has a lower flexibility than the membrane and wherein the fixing ring comprises fixing elements for fixing the fixing ring to the pressure meas~uring housing. The invention further relates to a housing as well as to a pressure measuring unit. La présente invention concerne une unité de membrane adaptée pour être utilisée dans un logement d~unité de mesure de pression, servant de préférence à mesurer la pression dans un circuit sanguin externe au corps comportant une membrane souple et un anneau de fixation qui est intégré avec la membrane de façon que la membrane et l~anneau de fixation forment un élément monobloc, l~anneau de fixation présentant une souplesse inférieure à celle de la membrane, et l~anneau de fixation comportant des éléments de fixation pour fixer l~anneau de fixation au logement de mesure de pression. L~invention concerne en outre un logement ainsi qu~une unité de mesure de pression.
