Improved therapy members useful for treating of sprains, muscle aches, orthopedic and skin injuries such as burns and other wounds are provided which make use of a pliable, self-sustaining, moisture sorbing gel including a humectant such as glycerin entrapped within a synthetic resin polymer matrix (e.g., a matrix containing acrylic acid or acrylamide monomer moieties). In one preferred embodiment, a body of the gel is encased within heat and moisture-permeable stretch fabric, and securing ties or the like are provided to permit the composite to be conformed to a body part and held in place. In use, such therapy wraps are either heated (as in a microwave oven) or refrigerated, so as to provide appropriate thermal treatment; it has been found that the preferred gel of the invention retains its pliability and other physical properties over a very broad temperature range, such as -20 DEG to 305 DEG F., and therefore the wraps of the invention can be used in many treatment contexts. It has also been discovered that the gel material can be applied directly to injured skin to in effect create a temporary skin with ideal air permeability. Furthermore, the moisture absorbing and desorbing properties of the gel create a moisture equilibrium between the gel, damaged skin and the atmosphere, thus promoting rapid healing. |
