KCI Medical knows the key to recovery is comfortable bed rest. The company, the UK operating division of US firm Kinetic Concepts, markets hospital beds for critically ill and bedridden patients. The company's wound care and acute care mattresses increase air flow and circulation to decrease the chances of developing bedsores, pressure ulcers, or pulmonary complications. KCI Medical also sells negative pressure wound and critical care therapy products including the V.A.C. (Vacuum Assisted Closure) wound closure device and the Prevena incision management system, as well as the LifeCell tissue regeneration products, on behalf of its parent. KCI Medical also conducts R&D efforts.
