An arrangement for pressure transmission comprising an outer casing (1) which by means of a membrane (2) is divided into two separate spaces (6,7) and which is provided with an inlet opening (3) for the conducting of a first fluid to one (6) of the said spaces (6,7) and a connection opening (5) for the connection of a second fluid from the other (7) of the said spaces (6,7) to a pressure-sensing device. The arrangement is characterized in that the membrane (2), preferably through hot-forming, is made to adhere tightly to at least a part of the periphery of the inlet opening (3) in such a manner that the inlet opening (3) communicates with only one (6) of the said spaces (6,7), whilst the connection opening (5) communicates only with the other (7) of the two spaces (6,7). The arrangement is intended first and foremost to be used for pressure-monitoring of blood in connection with dialysis or other similar extracorporeal blood treatment. |
