Method to determine blood flow in vessel entrance of haemodialysis unit; involves measuring arterial and venous pressures when vessel entrance is open to allow blood flow and closed to prevent blood flow

摘要

The method involves measuring the arterial, and venous pressures with an open vessel entrance, when the blood is flowing through it, and with a closed vessel entrance, when there is no blood flowing through it, while the blood flow in the extracorporeal blood circuit (2) is varied. The pressures are used to determine the blood flow for the open vessel entrance. An Independent claim is included for a device for implementing the method.
