Patent ID: 8864725

Claim:
A system for use in handling a medical liquid, comprising: a transfer adapter having a first transfer connection port rotatably interconnectable to a male luer fitting of at least one of a needleless syringe and an infusion tubing line port, and a second connection port; a patient connector having a first connection port rotatably interconnectable to a female luer fitting of an intravascular catheter access port, and a second connection port compatible with the second connection port of the transfer adapter, wherein the second connection port of the patient connector is interconnectable to the second connection port of the transfer adapter, wherein a first closed fluid passageway through the patient connector and the transfer adapter is automatically defined upon interconnection of the second connection port of the patient connector and the second connection port of the transfer adapter; a vial adapter having a first connection port selectively interconnectable to a vial containing a drug and a second connection port compatible with the second connection port of the transfer adapter, wherein the second connection port of the vial connector is interconnectable to the second connection port of the transfer adapter, wherein a second closed fluid passageway through the vial adapter and the transfer adapter is automatically defined upon interconnection of the second connection port of the vial adapter and the second connection port of the transfer adapter; and, a reservoir adapter having a first connection port selectively interconnectable to a fluid reservoir containing a medical liquid, and a second connection port compatible with the second connection port of the transfer adapter, wherein the second connection port of the reservoir connector is interconnectable to the second connection port of the transfer adapter, wherein a third closed fluid passageway through the reservoir adapter and the transfer adapter is automatically defined upon interconnection of the second connection port of the reservoir adapter and the second connection port of the transfer adapter, wherein said second connection port of said transfer adapter is alternately interconnectable to and disconnectable from said second connection port of each of said patient connector, said vial adapter, and said reservoir adapter, wherein said second connection port of said transfer adapter comprises one of an internally-threaded surface and an externally-threaded surface, and wherein said second connection port of said patient connector, said second connection port of said vial adapter and said second connection port of said reservoir adapter each comprise the other of an internally-threaded surface and an externally-threaded surface, complimentary to said one of said internally-threaded surface and externally-threaded surface.
