Abstract
An extracorporeal fluid circuit for performing hemofiltration defines within a flexible panel a flow channel that is free of an air interface. The flexible panel includes an in-line sensor region through which fluid pressure in the flow channel can be measured by an external sensor. The systems and methods enable sensing fluid pressure through the in-line sensor region using the external sensor. The flow channel can convey, e.g., waste from the hemofilter or replacement fluid for return to the individual.
