Abstract

A pressure measurement device usable for monitoring pressure of fluids such as blood, waste, and replacement fluid in a blood treatment system provides a reliable signal and other benefits by virtue of a number of features of the various embodiments disclosed. The pressure of fluid carried by a vessel or tube (150) is measured by measuring a change in shape of the vessel or tube via a sensor element (102) contacting it.
