Abstract
The present invention relates to a blanket for use with forced air convection systems, wherein the blanket includes an airflow deflector internal to the blanket and located near the air inlet port of the blanket. By providing a blanket with an airflow deflector, better distribution of air within the confines of the blanket may be achieved, which helps to reduce and eliminate problems associated with hot and cold spots within the blanket.
Claims6
A blanket for use with a forced air convection system, wherein said blanket includes an airflow deflector internal to said blanket, wherein said airflow deflector has a shape selected from the group consisting of an angular shape having a point oriented toward an inlet port of said blanket, a triangle, a dual co-acting triangle, a circle, a dual co-acting circle, and a polygon having arcuate surfaces, and wherein said airflow deflector is positioned adjacent the interior inlet portion of said inlet port of said blanket.
A method of preventing hypothermia, said method comprising:
- providing a blanket which may be used with a forced air convection system, wherein said blanket includes an airflow deflector internal to said blanket, wherein said airflow deflector has a shape selected from the group consisting of an angular shape having a point oriented toward an inlet port of said blanket, a triangle, a dual co-acting triangle, a circle, a dual co-acting circle, and a polygon having arcuate surfaces, and wherein said airflow deflector is positioned adjacent the interior inlet portion of said inlet port of said blanket;
- connecting said blanket to a supply source of forced air;
- and
- supplying forced air from said supply source to said blanket.
