1. An infrared device for prewarming intravenous (IV) solutions comprising:

  • (a) at least one cassette having a predetermined length of IV tubing passing therethrough with an inlet connectable to a source of IV solution and an outlet connectable to an IV infusion device;

    (b) at least one infrared energy-generating sheet positioned in said cassette adjacent to said predetermined length of IV tubing, said infrared energy sheet further comprising;

    i) a fiberglass support grid;

    ii) a matrix layer formed on said support grid, said matrix layer comprising a mixture of carbon and polymeric materials capable of producing infrared radiation in response to electrical current passed therethrough;

    iii) a pair of electrical conduction power strips along opposite sides of said layer;

    iv) a polymeric laminate enclosing said support grid, said matrix layer and said electrical conduction power strips, said polymeric laminate being substantially transparent to infrared radiation;

    v) input power terminals connected to said electrical conduction power strips; and

    (c) an electrical power source connected to said input power terminals for providing electrical power to be passed through said power strips and said matrix layer of carbon polymer mixture to generate infrared radiation therefrom.
