A gel-type adhesive composite bandage ( ) is provided which can be used in the treatment of fungus-involved or discolored toe nails, or for general wound treatment. The bandage ( ) includes a base ( ) having a preformed recess ( ), with a humectant-containing gel ( ) within the recess ( ). An adhesive-coated web ( ) is applied over the base ( ) and gel ( ). The web ( ) is strippable from the base ( ) with the gel ( ) adhered to the web ( ). In the use, the web ( ) is removed from the base ( ), and the exposed gel ( ) is applied directly to the affected toe mail or wound. The remaining portions of the adhesive-coated web ( ) is then used to maintain the web ( ) and gel ( ) in place. The gel ( ) preferably includes a polymeric matrix having a substantial quantity of water soluble humectant (for example, glycerin) entrapped within the matrix.

Starch-based superabsorbents are extended by blending with highly modified, low molecular weight starches. The dextrinized starches synergistically interact with the superabsorbents thereby permitting dilution without a commensurate reduction in the water absorbency. While the principal utility of the blends is the absorption of aqueous fluids, when hydrated they yield soft, smooth gels useful as high-quality thickening agents.
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. degree. to 305. degree. 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.
Therapy Member Including Internal Bladder With Surrounding Pliable Gel
An improved therapy member (10) for treatment of sprains, muscle aches and orthopaedic injuries is provided which is very flexible to permit the member to be placed in conforming relationship with a patient's limb or other body part, while also allowing effective hot or cold thermal therapy. The therapy member (10) preferably includes an internal bladder (12) having a fluid inlet (26) and a fluid outlet (28). The bladder (12) is substantially surrounded by a body of flexible, thermally conductive gel (32), the latter being encased within a flexible fabric-type sheath (34). An inlet/outlet fluid supply tubing assembly (16) is coupled with the bladder (12) in order to permit circulation of hot or cold fluid through the bladder (12) for therapy purposes. The gel (32) advantageously includes a water soluble humectant entrapped within a polyacrylamide matrix.
