Automatic intermitted blood purificn. process removes inpurities from blood and uses intermittent blood dialysis. The process involves (1) connection of blood to a circulation system outside the body containing an artificial kidney esp.dialyser, with suitable lines; (2) connection of a suitable supply of dialysis soln. esp. water and an outlet for the dialysate containing the impurities from the blood stream, (3) performing the dialysis operation across a suitable membrane. The automation has the following steps (a) analysis of the arterial blood stream to determine the correct rate of water removal and how many impurities are present for removal, components to measure being Na, K, Mg, HCO3-, CH3COO-, the concn. of CO2 and O2, and the general dilution w.r.t. the water content; (b) calculation of the throughput, rate for the blood and dialysate, the operating pressure to determine the required trans membrane pressure. Provides a rapid service to the patient, is easy and economic to operate for hispitals. It performs the operation with a min. of time and help by using a computer or central processor. |
