[Also in Division C3] Tubing for use as veins or catheters is made of polymers and treated to render it non- thrombogenic by contact with an acid having a molar concentration at least 5 followed simultaneously solution anticoagulant. Suitable resins are polyvinyl chloride, polytetrafluorethylene, polyethylene polypropylene. The anticoagulant heparin sodium, dicoumarol, warfarin indandion derivative distilled water saline. material preferably immersed until just prior use.
