A flange part is arranged on the outer side of the right end of the inflation tube, a third cavity connected with the second cavity is formed in the inner side of the flange part, a locking block is slidably connected to the outer side of the right end of the inflation tube, a fourth cavity located on the outer side of the flange part is formed in the inner side of the locking block, and a limiting ring fixedly connected to the inner side of the locking block is arranged at the left end of the fourth cavity. An air outlet connected with the third cavity is formed in the inner side of the left end of the flange part, an adjusting air bag located on the outer side of the air outlet is connected to the left end of the flange part in a sealed mode, an air conveying tube connected with the third cavity is arranged on the right side of the flange part, and a one-way valve is connected to the end of the air conveying tube.

Description

technical field [0001] The invention relates to a chest drainage tube, in particular to a drainage tube which relieves pain after thoracic surgery and is easy to fix. Background technique [0002] The most serious pain after thoracotomy is not the incision pain, but the severe pain caused by the friction between the front end of the drainage tube and the pleura. When the existing chest drainage tube is used, the main body of the chest drainage tube is usually inserted into the human body, and then the cavity is inserted into the cavity. The drainage tube is sewn together with the skin of the human body to fix the main body of the chest drainage tube to the human body. Although the main body of the chest drainage tube will not separate from the human body during drainage, the drainage tube will cause traction to the patient's skin and increase the pain of the patient. This method is inconvenient to use and increases the skin damage of the human body simultaneously. Contents...
