Description

A closed drainage device for clinical use in cardiothoracic surgery

technical field

The invention belongs to the technical field of cardiothoracic surgery, and more specifically relates to a clinical closed drainage device for cardiothoracic surgery.

Background technique

Closed thoracic drainage is to place one end of the drainage tube into the chest cavity, and the other end is connected to a drainage bottle that is lower than it, and the gas or liquid in the chest cavity is discharged by gravity, so that the lung tissue can reopen and restore function. As a treatment method, it is widely used in the drainage of hemothorax, pneumothorax, empyema and after thoracotomy, and plays a very important role in the treatment of diseases.

One is that the fixing effect of the joint between the existing drainage tube and the drainage bottle is very bad. When the patient turns over, sits, lies or moves the body, it is easy to cause the drainage tube to fall off and destroy the sealing effect of the joint, increasing the pain of the patient; Furthermore, the drainage bottle is generally placed on the ground, and due to unstable fixation, the drainage bottle will be accidentally knocked over, causing the drainage bottle to drag the drainage tube and increase the pain of the patient.

Therefore, in view of this, the existing structure and defects are researched and improved, and a closed drainage device for clinical use in cardiothoracic surgery is provided, in order to achieve the purpose of having more practical value.
