Abstract
A thermal blanket particularly suitable for post-operative treatment of body joints such as the shoulder, ankle, knee and elbow.

The exterior panel is of soft loop-providing pile fabric over substantially the entire exterior surface thereof. The developed outline of the blanket provides it with a form defining two main sections, one of which is provided with an attachment patch (preferably elastic) having a bodyside-facing hook-providing fabric for releasable attachment to the loop-providing pile fabric of the exterior panel of the other main section when the blanket is wrapped about a joint area for administering thermal treatment. The blanket also includes an integral T-shaped section having a strap portion and an elongated limb-wrapping band portion…
