Abstract: A syringe for use in a medical injection procedure in connection with connectors having a tapered fitting includes a syringe tip having a cooperating tapered fitting including a passage therein in fluid communication with an interior of the syringe. The syringe also includes a first connecting member having a radially inward threaded portion on an inner surface thereof adapted to connect to a first type of connector including a tapered fitting having at least one radially outward extending flange adapted to connect to the radially inward threaded portion of the first connecting member. In that regard, the first connecting member allows connection of the syringe to, for example, a standard luer fitting connector.

Abstract: A heat exchanger is provided which may be used in an integrated blood oxygenator and heat exchanger. The heat exchanger has a plurality of wave shaped sinusoidal channels on one or both sides. The heat exchanger has a cap attached at the upper end. The heat exchanger is disposed within a housing. The bottom end of the heat exchanger is bonded to the bottom end of the housing, and the upper end of the heat exchanger with the cap attached is spaced apart from the upper end of the housing. A liquid inlet and outlet are in fluid communication with the inner surface of the heat exchanger. A blood inlet and outlet are in fluid communication with the outer surface of the heat exchanger. The heat exchanger may be used with a blood oxygenating chamber. The blood oxygenating chamber contains a plurality of permeable hollow fibers which oxygenate blood flowing through the blood oxygenating chamber. The blood oxygenating chamber is in fluid communication with the outer surface of the heat exchanger and the blood outlet.
