Warming blanket
First Claim
1. A controlled temperature warming blanket, the warming blanket comprising a shell structure and a scrim insert layer disposed at the interior of the shell structure, wherein the scrim insert layer comprises a first elongate conductive wire structure operatively connected to a control element and at least a second elongate conductive wire structure operatively connected to the control element, wherein at least one of said elongate conductive wire structures is disposed in a switchback patterned arrangement within the scrim insert layer such that the first and second elongate conductive wire structures cross at defined positions along the length of the insert layer, said first and second elongate conductive wire structures being operatively connected within the insert layer remote from the control element such that a circuit is completed with the control element.

Abstract
A warming blanket incorporating an insert layer or sheet with a scrim having one or more pairs of heating and/or sensor wires arranged in a continuous pattern such that pair members are disposed in crossing relation to one another. The pair members may be cut and joined to establish electrical connections at defined crossing points to establish feedback loop circuits with a control element.
