Commonly called a bean bag positioner
Large, rubberized vinyl bags filled with thousands of tiny plastic beads. The Vac-Pac is molded around a patient then a suction line is attached to the special valve. As a vacuum is created, atmospheric pressure forces the beads together in the exact molded shape. When the suction line is disconnected, the Vac-Pac retains its exact molded shape. After surgery, the valve is opened and the Vac-Pac becomes soft again, ready for re-use.
