Abstract:
A labeling system to ensure that blood products are compatible with a patients blood type. A blood product housing, which is attached to a blood product, comprises a plurality of block-like projections and recesses corresponding to the antigens/antibody characteristics of a blood product. A patient housing, secured to the patient, comprises a plurality of mirror image three-dimensional block-like projections and recesses corresponding to the antigen/antibody characteristics of the patients blood. If the blocks and recesses of the housings mate and seat to one another this confirms the blood product is compatible with the blood of the patient. If the blocks and recesses of the housings do not mate and seat to one another this confirms the blood product is not compatible with the blood of the patient.
