## Abstract

The present invention relates to a blanket for use with forced air convection systems, wherein the blanket includes multiple inlet ports. By providing a blanket with multiple inlets, the user has the choice of positioning the air supply or blower unit and the supply hose on either side of the patient. In addition, in a preferred embodiment, the inlet ports are resealable, thus allowing the user to switch inlets during use.
