| 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.

First Claim:

We claim:
1. A connector assembly for use in assuring a proper blood type match when transfusing blood from a source to a patient, including:
- (a) a plurality of first connectors each adapted to communicate with said source of different blood type and including a blood carrying projection of first given dimensions differing from said first given dimensions of the remaining ones of said first connectors;
- (b) a plurality of second connectors each adapted to communicate with a vein in said patient and defining a blood receiving bore for communication with the patient's blood of different blood type and of second given dimensions differing from said second given dimensions of the remaining ones of said second connectors, said second given dimensions being complementary to said first given dimensions so that said first connectors are matably connectable each with only a respective one of said second connectors and only if the source and patient blood types associated with the first and second connectors match, any difference in said first and second dimensions preventing a proper connection from being carried out so that is is not possible to transfuse blood of one type into a patient having blood of another type; and
- additional means on each of said first connectors and each of said second connectors for indicating a match between the source and the patient blood type and thereby further indicating that a proper connection can be made between said first and second connectors.
