A plastic and inflatable hand splint designed for military and rescue operations, which is very affordable, compact and quick to deploy. The splint consists of two films that are fused together at the edges and contain channels that are filled with air. The air is under pressure, which compresses the film valve from the inside and closes the valve as soon as the air filling nozzle is pulled out. The splint will hold the arm in a temporarily fixed position so that the broken bone does not move until the injured person is transported to the hospital. A brainstorm was carried out with the client on what the final product could look like and a rough sketch was designed.
