ABSTRACT:
Blood is passed through a heparin coated mass of filamentous polyester resin, polyamide resin, polyacrylic resin, glass, steel, cotton or cellulose. Thereafter the blood is passed through a mass of the same filamentous material which is not heparin coated, for removal of its content of leucocytes and platelets preliminary to blood bank storage and/or use in transfusions. Passage of the blood through the heparin-coated filamentous resin in the first step prevents the blood from coagulating in the second step.
The apparatus employed for the treatment comprises a vessel having an inlet with means for connection to a source of untreated blood; an outlet with means for connection to a receiving vessel; and a packing comprising at least one filamentous material of the group listed above. The packing comprises an upstream portion comprising heparinized filamentous material and a downstream portion comprising filamentous packing material substantially free from heparin. The upstream heparinized portion prevents the blood from coagulating while passing through the downstream unheparinized packing portion which thereupon removes the leucocytes and platelets from the blood.
