ABSTRACT:
Method and apparatus for preventing mismatching of blood types between a blood bag and a patient. A first connector has a configuration coding corresponding to the blood type of the blood in the bag, and has means for piercing and providing access to the bag. Blood tubing fluidly connects the blood bag to the patient and has a second connector with configuration coding corresponding to the blood type of the patient. The first and second connection must have matching configurations in order to sealably connect and deliver blood to the patient, thereby preventing mismatches. Optionally, another pair of configuration coded connectors may also be provided to sealably connect the intravenous needle in the arm of the patient. These two pairs of configuration coded connectors may be used separately or together to guard against blood type mismatches.
