ABSTRACT:
Device for in-vivo purification of the blood, with which blood pumped from a vein is subjected to intensive ultrafiltration and the filtrate, together with a quantity of the substitution fluid volumetrically corresponding to the filtrate, is returned to the vein, which device combines a double lumen catheter, an inserted, initial tube pump, and an ultrafiltration filter, with connecting tubes between catheter and pump. A feed line, with an inserted, second pump for the substitute fluid, opens into the return line from the hemofilter to the catheter, and a feed line for anticoagulants opens into the feed line to the first tube pump; the ultrafilatration filter is also connected through a precisely adjustable valve to a measuring container in which the fluid drawn out of the system is collected. The device is particularly suited for the filtration of venous blood in intraaterial chemotherapy, the chemotherapeutic agents, particularly cytostatic drugs, being filtered out before they reach the heart, so that toxic secondary effects do not arise.
