    摘要: A method, apparatus and software program for measuring a parameter relating to the heart-lung system of a mammal are described. The method, software and apparatus can be implemented in a dialysis or other blood treatment apparatus comprising an extracorporeal blood circuit connected to a mammal; the circuit comprises a dialyzer, or other treatment unit, having a blood inlet, a blood outlet, a treatment fluid inlet and a treatment fluid outlet. The method comprises the steps of providing a pulse of a detectable substance in the blood circuit, measuring an integrated concentration of the detectable substance on the dialysis fluid outlet, determining the parameter based on the measurements on the dialysis fluid outlet.

    摘要: 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 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.

    摘要: A proposed blood treatment apparatus includes: a blood treatment unit, a pair of fluid pumps and a pair blood pumps. The blood treatment unit is configured to receive untreated blood and fresh blood treatment fluid, and emit treated blood and used blood treatment fluid. The fluid pumps are configured to pass blood treatment fluid through the blood treatment unit. The blood pumps are configured to extract untreated blood from a blood source, pass extracted blood through the blood treatment unit and deliver treated blood to a target vessel. Additionally, the fluid pumps are configured to control the operation of the blood pumps via the blood treatment fluid. Moreover, a flow control device is configured to control a trans-membrane flow between the blood side and the a fluid side of the blood treatment unit. Hence, for instance ultrafiltration can be adjusted to a desired level in a very straightforward manner.
