Title: Measuring fluid withdrawal rate in dialysis system - by aligning floats recording flow rates before and after membrane
Inventor: PERROT ERWIN
IPC: A61M1/16
Filed: 1980-05-31
Abstract: The rate of fluid withdrawal from blood flowing in a first circuit of a dialysis system through a semipermeable membrane into the dialysing fluid in a second circuit is measured by the difference in flow rates in the second circuit at locations before and after the membrane. This difference is shown by the levels of floats in two parallel transparent cylindrical casings movable vertically w.r.t. each other. The difference in flow rates is measured directly by the vertical shift required to align the two floats, as shown on a linear or circular scale. Alignment of the floats is recorded by coincidence of their images in the two sections of a prismatic mirror. Fluid withdrawal can be precisely and quickly monitored, irrespective of permanent or temporary variations in membrane dimension and condition. This permits integration of the total withdrawal without weighing the patient either at belated intervals or by expensive balance beds.
