A vacuum type long spine splinting device

An Neann Vacmat Vacuum Mattress has been purchased by Colac Branch for the transportation of trauma patients over long distances. The splint is made up of a tuff tarp type outer skin filled with tiny balls about 1 mm in diameter. The mattress is placed under the patient and then air is sucked out of the splint to form a rock hard device that prevents body movement. The mattress is used for patients being transferred with spine, pelvic and leg injuries.
