Abstract

The artificial kidney machine has an ultrafiltration control to indicate that the blood transfer level is acceptable. The dialysis fluid is passed alternately into one of two spheres a membrane acting as a pumping element to expel waste fluid. The new fluid passes through a degasser and into the filtration chamber. This has a longitudinal filter membrane with fluid on one side and the patient's blood on the other. After traversing this chamber the fluid is pumped out a take-off pumping sample fluid through a colorimeter. If the blood transfer level is not acceptable, an alarm sounds to warn the operator.
