Abstract
An artificial kidney includes measurement structure for measuring at least one physical characteristic of a fresh dialysis liquid and of used liquid. The measurement structure are disposed in a line portion common to a branch circuit to the feeder line of fresh dialysis liquid and to a branch circuit to the discharge line for the used liquid. Occluding structure permit the liquid to circulate exclusively in one or the other branch circuit. Due to this arrangement, it is possible to obtain the value of the physical characteristics of a patient's blood by calculation as frequently as desired, and to adjust the operation of the kidney permanently to a therapeutic objective set by the physician.
