The EMSoft splints are made with vinyl that is welded carefully and can be modeled quickly. They work for exposed fractures and use Velcro straps. X-rays can be done without removing the splints as well. The valve is held on the PVC material and uses a one-way system to keep air from moving in after the included vacuum pump is removed. This comes with a Ripstop case and uses 750 x 600 mm, 900 x 700 mm and 1100 x 800 mm sizes for its splints. This kit uses all three sizes for different kinds of injuries as they are to be treated.
