The invention discloses a pressurized drainage tube for a chest. Air bags are arranged on a
chest tube; the air bags are aerated to be expanded continuously, a shape of the aerated air bags is matched with the shape of
lung lobes, or matched with the shape of other spleens; when an organ is removed, the
chest tube is inserted into the chest and then the air bags on the
chest tube are aerated, so that the air bags effectively fill the chest to ensure
equalization of the pressure in a
human body, reduce even avoid the phenomenon of exudation of a chest wall; the pressure in the air bags can be increased or reduced according to the situation of exudation in the chest after operation, the pressure in the air bags is gradually reduced along with post
operation time, then residual
lung is expanded correspondingly, and finally the aim of removing the pressurized drainage tube is achieved; and meanwhile, the air bags companion the chest tube, once the air bags leak or air and blood exist in a cavity, the air and the blood can be drained by drainage holes in the chest tube through the chest tube timely, and the problems of
discharge of pneumatosis and dropsy in the chest are also effectively solved.
