UMD: Cold compresses or packs containing gels that retain cold temperature for a long period of time. These devices typically consist of compact plastic or fabric bags or pads containing pliable silica gels that can retain cold for a long time and are capable of conforming to the contour of the body; they are typically cooled by placing in cold water, a refrigerator, or a freezer. Gel cold compresses/packs are intended to apply cold therapy to a specific body surface; they are used mainly to reduce pain, swelling, bruising, and bleeding.
