Abstract:
A blood product identification system which comprises:a blood product housing having a face and at least one three-dimensional blood product indicium formed in the face, the shape of the blood product indicium being one piece of a set of two geometrically complementary pieces, the blood product indicium corresponding to the theoretical compatibility characteristics of a blood product;a patient housing having a face and at least one three-dimensional patient indicium formed in the face, the shape of the patient indicium being the second piece of the set, the patient indicium corresponding to the theoretical compatibility characteristics of a patient's blood whereby when the patient housing is engaged in a face-to-face relationship with the blood product housing, if the blood product indicium and the patient indicium mate and seat then the blood product housing and patient housing will seat indicating that the characteristics of the blood product is of a type which is compatible with the characteristics of the patient's blood and if the blood product indicium and the patient indicium do not mate and seat then the blood product housing and patient housing will not seat indicating that the characteristics of the blood product is of a type that is not compatible with the characteristics of the patient's blood; andmeans for preventing the mating and seating of the blood product indicium with the patient indicium when the characteristics of the blood product is of a type that is theoretically compatible with the characteristics of the patient's blood but physical compatibility has not yet been determined, the means for preventing being distinct from the blood product and patient indicia and comprises a cavity on one of the housings, a mating protuberance on the other housing and a removable tab positioned to prevent the cavity and the protuberance from mating.
