Thermal conditioning apparatus

A thermal conditioning apparatus for delivering a thermal medium to a patient comprising:

• a first material layer having a substantially planar configuration and including a first and second plurality of orifices, the first plurality of orifices being smaller than the second plurality;
• a second material layer having a substantially planar configuration, the first material layer bonded to the second material layer at portions thereof to define a substantially u-shaped inflatable medium delivery space of a configuration to extend about the sides of a patient;
• an inlet portion in connection with the medium delivery space to receive a thermally conditioned medium and disposed closer to the first plurality of orifices than to the second plurality of orifices wherein a lower volume of thermal medium is delivered to the patient through the first plurality and a higher volume of thermal medium is delivered to the patient through the second plurality;
• and
• a non-inflatable cover portion formed of the first and second material layers and extending laterally from one of an extending portion of the u-shaped space and of a length to fold over and cover the patient, wherein the cover portion comprises a plurality of flap portions.

• a second material layer having a substantially planar configuration, the first material layer bonded to the second material layer at portions thereof to define a substantially u-shaped inflatable medium delivery space having a pair of extending portions of a configuration to extend about the sides of a patient;
• a non-inflatable strip portion extending between the pair of extending portions for extending beneath the patient to hold the u-shaped inflatable medium space relative to the patient;
• an inlet portion in connection with the medium delivery space to receive a thermally conditioned medium and disposed closer to the first plurality of orifices than to the second plurality of orifices wherein a lower volume of thermal medium is delivered to the patient through the first plurality and a higher volume of thermal medium is delivered to the patient through the second plurality;
• and
• a non-inflatable cover portion integrally formed of the first and second material layers and extending laterally from one of the extending portions of the u-shaped medium space and of a length to fold over the extending portion and cover the patient, wherein the cover portion comprises a plurality of flap portions whereby one or more of the flap portions can be selectively opened to expose a portion of the patient.
