Abstract

An ultrafiltration control appts. for an artificial kidney incorporates a dialysing liq. circuit connected to a first compartment of a haemodialyser. The second compartment is connected to the vascular system of a patient. The two compartments are sepd. by a semi-permeable membrane. The first circuit provides for a constant vol. of the dialysing liq. in circulation. The circuit includes a pump; an extn. zone and valves. The pump circulates dialysing liq. in contact with the membrane. The extn. zone incorporates a bubble-trap with a sight glass, connected to a pump which extracts quantities of liq. equal to the quantity of ultrafiltrate taken out. Two valves control the period feed of fresh liq. to, and discharge of exhausted liq. from, the circuit. Two other valves allow isolation of the part of the circuit passing through the extraction zone and the haemodialyser, from the part of the circuit connected to the source and discharge of liq., while the exhausted liq. is being replaced by fresh liq. The haemodialysis a carried out under optimum conditions because of the high circulation speed and frequent renewal of the dialysing liq. The quantities of ultrafiltrate are under close control and can be determined in advance according to the patient's condition.
