Abstract: A method of pressure control in the pneumatic compression bandage and a pneumatic compression bandage includes a cuff with a chamber to be filled with a pressurized fluid. The device has a harness to fasten the cuff in the wound area and a control and pumping unit (6) connected pneumatically to the chamber in the cuff via a hose. The unit includes an electrical pump, an electromechanical valve connected electrically with the unit, a pressure sensor connected electrically with the unit (6). The controller of the pressure in the cuff chamber is of the PID type, including a proportional, integral and derivative modules, to control the electric pump to increase pressure in the cuff chamber and to control the valve to reduce pressure in the cuff chamber.
