The invention relates to an intermediate element for a medical extracorporeal fluid line which is designed to conduct a fluid, in particular blood, having a main part (2) which extends between two connection parts (3, 4). A flow channel (5) for conducting the fluid passes continuously through the main part (2) and the connection parts (3, 4), wherein the connection parts (3, 4) are designed to hydraulically connect the main part to the fluid line. A receiving area (8) is arranged on the periphery of the main part (2), said receiving area being designed to receive a measurement value transmitter. An opening (7) to the flow channel (5) is arranged on the receiving area (8) in the main part (2), said opening being sealed in a fluid-tight manner towards the receiving area (8) by means of an elastic element. The receiving area (8) is designed to receive a measurement value transmitter, which is designed as a gas sensor (21), of a sensor device for measuring at least one gas contained in the fluid. The elastic element is a diffusion element (10) which is permeable to at least one gas, and the diffusion element (10) is bonded to an edge (12) of the opening (7) in a connection region (11). |
