Abstract: A thermal pack unit or compress is formed by adhesively securing two relatively thin pieces together. The first piece is a plastic sheet having one or more interconnecting channels or grooves formed in a surface thereof to form a path for the circulation of the thermal fluid. The second piece is a relatively thin sheet of non-resilient bendable metal which is secured over the channeled surface of the plastic sheet for sealing the top portion thereof so the fluid inputted at one end of the channeled space is able to flow or circulate therethrough and then be outputted from an outlet in the channeled space. The metal sheet is bendable so that the pack unit can be readily conformed to a given contour of the human body such as the irregular areas about the eyes, nose and ears of a person and the characteristics of the metal insure that the contoured shape will be retained to aid in keeping the pack unit positioned while in use.

Abstract: A pack unit or compress is formed in two halves each containing one or more channels and the halves are arranged face-to-face with a separator sheet covering the channels almost to their blind ends. The cold or, if desired, hot thermal fluid may flow through all of the channels in one of the halves simultaneously and then around the edge of the separator sheet in the blind ends of the channels and then through the channels of the opposite half to exit from the outlet end thereof. The unit may be appropriately contoured to closely fit a selected portion of the anatomy and can be used to continuously apply a uniformly cold compress to patients whose skin surfaces have recently undergone plastic surgery, skin grafting or the like to reduce swelling and to slow down the tendency of the newly-applied skin to die before the flow of blood begins.
