    摘要: 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.

    摘要: Artificial kidney comprises a hemodialyzer connected in a dialysis liquid circuit which is in the form of a loop the volume of which is essentially invariable. The circuit is open to the atmosphere and comprises a circulating pump arranged upstream of the hemodialyzer. Means are provided for drawing off and measuring, outside the said circuit, amounts of liquid equal to the amounts of ultrafiltrate which it is desired to remove from a patient's blood stream. A variable hydraulic resistance is provided downstream of the hemodialyzer and comprises a float, the resistance being operative to keep the dialysis liquid at an essentially constant level in the circuit in order automatically to regulate the pressure of the dialysis liquid in the hemodialyzer.
