<p>A method and medical machine for calibrating a peristaltic pump (36, 39) intended to be used in connection with the medical machine, such as a dialysis machine. The machine comprises an internal fluid flow meter (18, 19). Fluid is introduced into the pump segment (36) and is pumped by the peristaltic pump at a substantially constant rotation rate. Three different inlet pressures are obtained and measured by a pressure meter (16) and the corresponding fluid flow is measured by the internal fluid flow meter (18, 19) for obtaining calibration pair values. A calibration curve is calculated from said calibration pair values by a computer (23) inside the medical machine. The actual fluid flow rate is determined by said computer (23) from said calibration curve based on the actual inlet pressure and the actual revolution rate of the propelling means.</p> |
