Abstract

Richard Lower made the first blood transfusion in 1665, but the wide use of the technique in medicine is quite recent. One of the difficulties lay in the coagulation of the blood during the transfer. Accordingly, the blood is generally treated with sodium citrate to prevent this. It is known that calcium in the blood has something to do with the coagulation and probably with the agglutination. It was decided to study blood from which the calcium had been removed. To remove the calcium we adopted the principle used in removing calcium from hard water, that is, passing· it over a zeolite. Blood is viscous-especially coagulated blood-hence it was necessary to use suction to force it through the tube filled with zeolite. The tube was attached to a filter flask which in turn was attached to a filter pump. In this way the blood was passed through the zeolite bed successfully.
