Publication number: 20220313887Abstract: A pressure-measuring assembly for measuring the internal line pressure of a line system of an extracorporeal blood treatment machine. The assembly includes a pressure sensor that is connectable to a pressure receiver by a rigid, bending-resistant fluid line. The pressure receiver is connected or connectable to the line system. The pressure sensor converts a fluid pressure signal from the fluid line into an electrical signal. An electrical line connects the pressure sensor to electronics to process the electrical signal. A retainer directly or indirectly retains the pressure sensor and forms, at least in parts, an inner channel, in which the electrical line is led. Alternatively, the retainer is a substantially plastically curvable bar which has, at one axial end portion, a fastening device for mounting on a stationary base and, at the other axial end portion, an articulation site for the pressure sensor or the pressure receiver.Type: ApplicationFiled: June 4, 2020Publication date: October 6, 2022Inventor: Kai-Uwe Ritter
