ABSTRACT:
A specially designed first adaptor or connector is permanently attached to a blood source secured from a donor and kept at a hospital blood bank. This first connector is color-coded and has the type blood in the source imprinted thereon. Further, it includes a blood carrying projection of given dimensions. A second connector, in turn, is permanently secured to a blood infusion line or tube leading from a potential recipient or patient's vein. This second connector is also color-coded and provided with an imprint of the patient's type blood. Further, the connector includes a blood receiving bore of given dimensions, the color coding, printing of the blood type and the given dimensions for the second connector being determined by the blood type of the patient. When the blood type of the source and the blood type of the patient match, then the first and second connectors are of the same color, have the same blood type printed thereon and the referred to given dimensions of each connector are complementary so that a proper connection can be effected for the transfusion of blood from the source to the patient. If the patient's blood type is different from the source, it is impossible to effect a connection between the first and second connectors so that errors in mismatch are eliminated.
