Abstract
A pneumatic, disposable, temperature control blanket pressurized with a heated or cooled air comprises an inflated envelope having a lower sheet having openings formed therein for impinging the air upon a patient. Air is introduced into the blanket envelope at a single inlet port, and an interior flexible conduit or subtube located within the envelope communicates with the inlet for distributing freshly introduced air throughout the blanket length with little temperature loss.
