Container for use with blood warming apparatus

An assembly for placing a flow of fluid in thermal contact with a warming apparatus, the warming apparatus having a heated elongated mandrel with a generally smooth, frustoconical outer surface defining a central axis, the mandrel defining a first radial groove on a lower portion of the mandrel and a second radial groove on an upper portion of the mandrel, the assembly comprising:

• an outer restraint adapted to slidingly fit about at least a portion of the length of the mandrel, the restraint having two ends and an inner surface, the inner surface defining a longitudinal axis, the inner surface and outer surface of the mandrel forming a boundary for a passageway for the flow of the fluid through the assembly, the first radial groove and restraint forming a boundary for an inlet manifold portion of the passageway, the inlet manifold being proximate one end of the assembly;
• and
• first means for directing an inlet flow of fluid into and along the inlet manifold;
• and
• the restraint and second radial groove defining the boundary of an outlet manifold portion of the passageway and second means for directing a flow of fluid from the outlet manifold in a direction generally aligned with the outlet manifold;
• and
• a sterilized bag including an inlet and an outlet and two sidewalls attached to each other to form and seal the passageway, the bag being attached to the restraint and disposed generally along the inner surface.

An assembly for placing a flow of fluid in thermal contact with a warming apparatus, the warming apparatus having a heated elongated mandrel with a generally smooth, frustoconical outer surface extending from a first end to a second the end, the first end having a smaller radius than the second end, the mandrel defining a central axis, the mandrel forming a first radial groove formed on a portion of the first end of the mandrel, and extending about said axis generally normal to said axis and a second radial groove on a portion of the second end of the mandrel, the second groove extending about said axis generally normal to said axis, the assembly comprising:

• an outer restraint adapted to slidingly fit about at least a portion of the length of the mandrel, the restraint having a first end and a second end corresponding to the first end and second end of the mandrel and an inner surface, the inner surface defining a longitudinal axis, when the restraint fitted about the portion of the length, the inner surface and outer surface of the mandrel forming a boundary for a passageway for the flow of the fluid through the assembly with the first radial groove and restraint forming a boundary for an outlet manifold portion of the passageway;
• an outlet attached to the restraint proximate the first end of the restraint and arranged relative to the restraint to direct an outlet flow of the fluid from the outlet manifold in general radial direction generally aligned with the outlet manifold;
• and
• an inlet attached to the restraint proximate the second end of the restraint and arranged relative to the restraint to direct an inlet flow of the fluid into the passageway in a generally radial direction;
• and
• a sterilized bag including an inlet and an outlet and two sidewalls attached to each other to form and seal the passageway the bag being attached to the restraint and disposed generally along the inner surface.

• an inlet to the passageway attached tot he restraint at a first end of the restraint and the outlet attached to an opposite end of the restraint;
• the inner surface being configured in a generally smooth frustoconical configuration such that the passageway provides for flow of fluid in a generally sheetlike configuration extending from said first end to said opposite end;
• and
• a sterilized bag including an inlet and an outlet and two sidewalls attached to each other to form and seal the passageway, the bag being attached to the restraint and disposed generally along the inner surface.
