A medical device embodied as a stretcher, body bag, or mattress is disclosed. The device includes water and a selectively breakable package. The selectively breakable package includes a chemical, such as ammonium nitrate, which when mixed with water will cause an endothermic reaction. In use, the package is broken in order to cause the water to cool. The cooled water absorbs heat from an injured person placed on the device, thereby minimizing inflammation that may occur from injuries sustained by the person.
