Background

Chest drainage is a medical operation aimed at draining foreign matters such as liquid, gas or blood in the chest by inserting a drainage tube in the chest. In chest drainage, a physician may insert a drainage tube by puncturing the chest cavity to drain fluids and gases from the chest cavity. This procedure is commonly used to treat pleural effusions, pneumothorax, pneumonia, etc., and is often used for post-operative drainage of the chest and treatment of pleural effusions.

In practical situations, since the effusion remains in the cannula, after the cannula is taken out of the body of a patient, the effusion may remain on the inner wall of the drainage tube, and the effusion remained in the puncture needle and the cannula may flow to other places, so that clothes, the ground and other positions are soiled, the cleaning difficulty of a user is increased, and the puncture needle is not timely sealed after being used, is easy to scratch unintentionally, and causes the spread of diseases.
