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.
A pneumatic compression bandage (7) intended particularly for preventing hemorrhagic complications following medical device implantations in cardiac electrotherapy, including a cuff (4) with a chamber (9) to be filled with a pressurized fluid, a harness (8) used to fasten the cuff (4) in the wound area and a control and pumping unit (6) connected pneumatically to the chamber (9) in the cuff with a connection hose (5). This control and pumping unit (6) includes an electrical pump, an electromechanical valve connected electrically with the control and pumping unit, a pressure sensor connected electrically with the control and pumping unit (6), as well as memory and a system processing digital information, and a user interface in the form of buttons, light and sound indicators, wherein the pressure controller in the cuff (4) chamber (9) is a PID controller, meaning it includes a proportional (P), integral (I) and derivative (D) modules, to control the electric pump to increase pressure in the cuff (4) chamber (9) and to control the valve to reduce pressure in the cuff (9) chamber (4).
