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.

Claims

1. A blanket for use with a forced air convection system,

wherein said blanket includes an inflation chamber with multiple inlet ports;

wherein said multiple inlet ports may be reversibly sealed with a reversible sealing means comprising folding wire or plastic bars such that at least one of said multiple inlet ports remains closed when the blanket is supplied with forced air.

2. A blanket according to claim 1, wherein said blanket includes two inlet ports.
