Instant reusable compress

摘要

An instant reusable gel compress for applying cold or heat to a human or animal body part. The compress contains crystals of ammonium nitrate or calcium chloride, a water soluble acrylic polymer and an enclosed bag of water within a sealed, durable, flexible, plastic, bag-like container. When the interior water bag is broken, an immediate thermal reaction and simultaneous gel formation results. The resulting gel compress is then applied to the body part for cold or heat treatment. When the cold or heat is dissipated the gel compress itself may be chilled or heated again by an external source and then reused.
