As shown in fig. 1-3: a novel multifunctional pleuroperitoneal cavity drainage tube comprises a double-cavity drainage tube 1 consisting of a main drainage tube 1-1 and an auxiliary drainage tube 1-2, wherein the sections of the main drainage tube 1-1 and the auxiliary drainage tube 1-2 are semicircular, and are attached back to form the double-cavity drainage tube 1 with a circular section, the tail ends of the main drainage tube and the auxiliary drainage tube are separated and respectively provided with a buckle (5, 6), and the tail end of the main drainage tube 1-1 is provided with a flow speed control valve 4; an air bag 3 which is conical after being inflated is arranged at a position of the double-cavity drainage tube which is 10-12cm away from the front end of the drainage tube, and an inflation tube 8 is connected on the air bag 3; a plurality of drainage side holes 2 are respectively arranged on the arc-shaped side walls of the front parts of the main drainage tube and the auxiliary drainage tube; the length scales 7 are arranged on the outer edge pipe wall of the back-to-back binding surface of the main drainage pipe and the auxiliary drainage pipe.

The utility model discloses when using, put into thorax or abdominal cavity through the seal wire guide with two-chamber drainage tube front end, the drainage tube front end is blunt nosed coniform and not only conveniently puts into but also avoids the stimulation to thorax or peritonaeum. When the catheter is placed, the placement depth of the drainage tube can be observed through the scales on the catheter wall, and the catheter is stopped when the placement depth of the double-cavity drainage tube exceeds the air bag. Further, gas is injected into the air bag through the inflation tube by an injector, the air bag is expanded into a cone shape after the gas is injected, and then the air bag is connected with the air bag joint to prevent the gas in the air bag from overflowing to keep the air bag in an expansion state. The double-cavity drainage tube is slightly pulled outwards to enable the expanded air bag to seal the puncture point so as to avoid the overflow of pleural effusion or peritoneal effusion and prevent the catheter from dropping out, thereby not only avoiding the pain of puncturing the catheter again and reducing the work of changing the medicine caused by the seepage, but also avoiding the pain caused by the traditional mode of fixing the drainage tube on the skin by sewing the drainage tube. Then, the rear end of the main drainage tube is connected with a drainage bag, and effusion is continuously drained through a side hole on the side wall of the drainage tube, the drainage tube and the drainage bag. The rear end of the drainage tube is provided with a buckle at the joint of the main drainage tube and the joint of the auxiliary drainage tube, and the buckle can seal the drainage tube to avoid effusion from flowing out and outside air from entering the pleuroperitoneal cavity.

When thick and difficult drainage of pleural or abdominal dropsy appears, can inject into normal saline through vice drainage tube 1-2 and continuously wash and dilute thick dropsy to pleural or abdominal cavity, both avoid the dropsy to thicken and block the drainage tube, can make the dropsy drainage reach the purpose of thorough drainage dropsy more easily again, prevent that thick dropsy from depositing in thoracic or abdominal cavity. Meanwhile, when the thoracic cavity or the abdominal cavity is required to be filled with the medicine, the medicine can be filled through the auxiliary drainage tube. When traditional single chamber drainage tube need wash or annotate medicine, need to break repeatedly the connection between drainage tube and the drainage bag, wash or annotate the back and connect drainage bag and drainage tube. The arrangement of the double-cavity drainage tube avoids the inconvenience brought by the operation and reduces the infection risk. The tail end of the auxiliary drainage tube can be connected with a negative pressure suction connector, and when pneumatosis exists in the thoracic cavity or hydrops drainage is not thorough, hydrops can be drained through negative pressure or the hydrops can be drained completely. When main drainage tube blocks and the hydrops is clean as yet not completely drainage, can continue the drainage hydrops through vice drainage tube, avoid the drainage tube abandonment and need puncture once more, increased the function of drainage tube, the practicality is stronger.

When the effusion is drained, the first 24 hours of pleural effusion is required to be not more than 600ml, and the abdominal effusion is not more than 1000 ml. A large amount of effusion is drained in a short time, and acute pulmonary edema or related complications such as hepatic encephalopathy can be caused. Therefore, it is desirable to control the rate at which fluid is drained. When the accumulated liquid volume is large and the pressure is high, the automatic drainage speed is high, a flow speed control valve is arranged at the rear end of the main drainage tube, the distance between the threads and the pressure bearing plate is reduced, and the drainage speed is controlled; when the effusion volume reduces pressure and diminishes, automatic drainage speed is slow, increases the distance between screw thread and the bearing plate, makes effusion drainage speed in normal range to realize the more accurate regulation of drainage speed.

When the accumulated liquid or the accumulated gas is completely drained and the medicine is not needed to be injected, the drainage tube needs to be pulled out to finish the treatment. Before tube drawing, the air in the air bag is sucked completely by an injector through the rear end of the air bag, so that no blockage exists between the drainage tube and the puncture point, and then the drainage tube is smoothly drawn out of the body.
