<p>Blood dialysis appts. contains a dialyser divided into two sections, one section for the blood to be purified and the other for the dialysis liq., the two sections being sepd. by the dialysis membrane. This membrane also allows ultrafiltration to take place across it. The section through which the dialysis liq. flows is part of the dialysis liq. which comprises a volumetric feed pump and an outflow pump, the two pumps having the same flow rate, a pressure loss adjuster, a pump for raising the pressure and a pressure regulator. This adjusted to let liq. escape from the circuit when the pressure in the circuit exceeds a pressure corresponding to no ultrafiltration. Appts. ensures a precise adjustment of the ultrafiltration flow whatever variations may occur in the factors working on this flow and in spite of diverse characteristics in the dialysis membranes.</p> |
