ELECTRIC HEATING PAD WITH ELECTROSURGICAL GROUNDING
First Claim
1. An electric heating pad with electrosurgical grounding comprising a heated underbody support, heated mattress or heated mattress overlay, the heating pad with electrosurgical grounding comprising:
- a flexible sheet-like heating element including an upper edge, a lower edge, and at least two side edges;
a flexible sheet-like grounding electrode including an upper edge, a lower edge, and at least two side edges;
a shell covering the heating element and grounding electrode and comprising at least two sheets of flexible material; and
a weld coupling the two sheets of flexible material together about the edges of the heating element and grounding electrode, wherein the weld is one of a RF weld, ultrasonic weld, or a heat bond, wherein the two sheets comprise PVC or urethane.

Abstract
An electric heating pad with electrosurgical grounding comprising a heated underbody support, heated mattress or heated mattress overlay. In an illustrative embodiment the heating pad with electrosurgical grounding may include a flexible sheet-like heating element including an upper edge, a lower edge, and at least two side edges and a flexible sheet-like grounding electrode including an upper edge, a lower edge, and at least two side edges. A shell covering the heating element and grounding electrode and comprising at least two sheets (e.g., may be one sheet of material folded over to form two sheets) of flexible material, and a weld coupling the two sheets of flexible material together about the edges of the heating element and grounding electrode, wherein the weld is one of a RF weld, ultrasonic weld, or a heat bond, wherein the two sheets comprise PVC or urethane.
