Methods for measuring intermediate elements for medical extracorporeal fluid lines, medical extracorporeal fluid systems, and gases contained in human or animal body fluids guided in medical extracorporeal fluid systems.

摘要

An intermediate element for a medical extracorporeal fluid line designed to conduct a fluid, such as blood, has a main part extending between two connection parts. A flow channel passes continuously through the main part and the connection parts. The connection parts hydraulically connect the main body to a fluid line. On the periphery of the main part a receiving area is arranged, which is designed to receive a measurement value transmitter. An opening to the flow channel is defined in the receiving area and is sealed in a fluid-tight manner towards the receiving area by an elastic element. The measurement value transmitter is a gas sensor of a sensor device for measuring at least one gas contained in the fluid. The elastic element is a diffusion element, which is permeable to at least one gas. The diffusion element is bonded to an edge of the opening.
