1. Field of the Invention
This invention is in the field of medical instruments for processing body fluids including an instrument to perform hemodialysis.
2. Description of the Prior Art
The usual approach to performance of single access dialysis is to pump blood into the dialyzer by a roller pump on the arterial or inflow blood tubing. The venous limb has an air-filled tubing leading to a pressure gauge and a downstream clamp. The reading of the pressure gauge is the controller of the flow into the dialyzer, and the volume in the dialyzer. On inflow of blood to the dialyzer, the venous limb is clamped, the blood pump started, and the blood volume and pressure increase in the dialyzer and venous drip chamber. The relationship of pressure to the volume in the dialyzer is determined by the "compliance" or "stiffness" of the dialyzer. On outflow,...
