technical field

The utility model relates to the technical field of medical devices, in particular to an improved chest cavity closed drainage tube.

Background technique

Closed thoracic drainage tube is a kind of drainage material that must be used after thoracic surgery and hemopneumothorax. However, there are some deficiencies in the current chest drainage tube. First of all, the fixation of the chest tube is very important. If the chest tube falls off accidentally, it will cause the chest cavity to communicate with the outside world, resulting in an open pneumothorax, which is life-threatening. Therefore, doctors usually use sutures to fix the patient's skin when fixing the tube, which causes the patient to be stretched and cause severe pain when moving. Secondly, when the thoracic cavity is closed for drainage and clamping, the current hospital uses vascular forceps to fold the drainage tube in half and then clamp it. This method leads to a shortened drainage tube and a large volume of the vascular clamp, which is prone to inconvenience.
