Abstract

The invention relates to a catheterized drainage device for thoracic cavity closed drainage. The catheterized drainage device for thoracic cavity closed drainage comprises a body cavity balloon sleeve, a catheter sheath arranged outside the body cavity balloon sleeve and an external drainage tube can be connected with the body cavity balloon sleeve; a monomial balloon control tube is arranged in the body cavity balloon sleeve, an opening is formed in the inner end of the catheter sheath, the inner end of the catheter sheath is provided with an inclined plane, and the catheter sheath comprisesa first sheath body and a second sheath body which can be combined with the first sheath body; the inclined plane is sequentially divided into a first arc-shaped section, a straight section and a second arc-shaped section from one end to the other end, the first arc-shaped section is tangent to the straight section, and the straight section is tangent to the second arc-shaped section. According tothe catheterized drainage device for thoracic cavity closed drainage, sharp instrument cutting and blunt instrument separation are avoided through the detachable catheter sheath, the pain and bleeding risk of patients is reduced, the catheterization success rate and efficiency are improved, the practical operation comfort and controllability are improved through scientific pen type design and precise scale marking, and operation is more convenient and faster.

Description

technical field [0001] The invention relates to a tube drainage device for closed chest drainage. Background technique [0002] The pleural cavity is a closed potential cavity formed by the two layers of the visceral wall of the pleura turning and moving at the root of the lung. There is no gas in the cavity, only a small amount of serous fluid (5-15ml), which can reduce friction during breathing. The cavity is negative pressure, which is conducive to the expansion of the lungs and venous blood. with lymph reflux. Air in the pleural cavity is called pneumothorax; hemothorax in the pleural cavity is called hemothorax; fluid in the pleural cavity is called pleuraleffusion. Pleural hemorrhage, pneumothorax, and effusion caused by any reason will seriously affect the respiratory function of the patient to a certain extent. According to the symptoms of intrapleural pneumatosis, effusion, and hemorrhage caused by different reasons, the choice of closed thoracic drainage Sexual ...
