Closed thoracic drainage is a drainage tube with one end placed in the thoracic cavity and the other end connected to a water-sealed bottle positioned lower than the drainage tube to discharge air or collect fluid in the thoracic cavity. Closed drainage of the thoracic cavity can effectively avoid the occurrence of the condition of pneumothorax caused by hydrops in the thoracic cavity after operation. The patient who puts into thorax closed drainage device moves the transportation in-process in order to prevent liquid in the liquid seal bottle and flow backwards in the drainage tube. Medical personnel need to clip the two ends of the drainage tube. The existing operation mode is to clamp two vascular clamps on a drainage tube. However, the disadvantage of this method is that 1, the medical staff can not carry the vascular clamp with them and it is inconvenient to take it out. 2. The vascular clamp has a large weight, and easily produces the traction effect to the drainage tube in the carrying and transferring processes, so that the wound of a patient is painful, and the risk of accidental tube drawing is increased. 3. Because the drainage tube of the closed thoracic drainage device has thick tube diameter, thick tube wall and hard material, if a common catheter clamping device is adopted, the stress fracture of the drainage tube or the permanent deformation of the drainage tube is easy to influence the subsequent drainage function.
