FIELD: medical equipment.SUBSTANCE: group of inventions is intended for medical use and belongs to the disposable pleural drainage system, which allows all doctors to drain the air (pneumothorax), blood (hemothorax) and all other fluids (hydrothorax) accumulated abnormally in the chest cavity (pleural cavity). Disposable pleural drainage system includes a pleural drainage apparatus； tubular cutting guide made of PVC and silicone； drainage bottle, which has a corrugated or accordion shape and can be reduced or increased in size； connecting tube, which provides a connection between the drain tube and the drain bottle； syringe injector； scalpel； antiseptic pad； medication local anesthesia. Aforementioned pleural drainage apparatus of a disposable pleural drainage system includes a drainage tube, made of PVC and silicone； at least one hole in the drainage tube； inflatable balloon that may be located at different points in the drainage tube and may be inflated and deflated； inflatable balloon channel used to inflate or lower the inflatable balloon； hollow and movable cover on the drainage tube； clamping device, which is used to prevent the flow of air and liquid by compressing and blocking the drainage tube and to close the end of the wire channel a check valve device designed to prevent backflow of fluid or air, supplied to this channel using a syringe injector for inflating the inflatable balloon apparatus at the rear end of the inflatable balloon channel； wire channel closed at one end, which directs the drainage tube to the desired area after the first entry into the pleural cavity between the ribs； guide wire, which is located in the wired channel, and directs the drainage tube to the desired area after the first entry into the pleural cavity； the flushing channel open at both ends, which allows flushing the pleural cavity with fluids, including immune serum, after the drainage tube is placed in the pleural cavity； a closing device that is used to close one open end
