Abstract

See full text

A pressure measurement system for use in blood circuits comprised of a pressure sensing pod and a force measurement device. The pressure sensing pod can include a flexible, moveable, fluid-impermeable diaphragm and can be formed via either a one-shot or a two-shot molding process. A mechanical engagement member of the force measurement device engages with a mechanical engagement feature of the diaphragm, and the engagement member is operative to move in concert with movement of the engagement feature of the diaphragm based on pressure variations with the pressure sensing pod. The force measurement device generates and outputs to a processor a signal based on detected force associated with movement of the engagement member.
