ABSTRACT:
A system for warming blood or other liquids to body temperature and maintaining the liquid at that temperature for infusion into a patient. The system is characterized by a cylindrical condensation liquid heating chamber having an inner tubular air heater. A cylindrical heat retaining shell surrounds and is spaced from the outer wall of the heating chamber. A flat flexible heat exchanging liquid warming envelope is held clamped between the outer wall of the heating chamber and the surrounding shell. An external outer elongated air hose is connected at one end to a warmed air outlet from the air heater and extends to the patient and surrounds an inner elongated warm liquid flow line to maintain the temperature of the liquid.
