Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an integrated chest drainage device for preventing backflow. Background Art

[0002] At present, disposable chest drainage devices are widely used in clinical practice and are suitable for the treatment of pneumothorax and pleural effusion caused by various reasons and patients who need closed chest drainage after surgery. Closed chest drainage is to place one end of the drainage tube into the chest cavity, and the other end is connected to a water seal bottle at a lower position, so as to discharge gas or collect fluid in the chest cavity, so that the lung tissue can reopen and restore function. The most commonly used disposable double-chamber water seal bottle in clinical practice is divided into a fluid chamber and a water seal chamber. The fluid chamber is divided into three interconnected chambers with different scale standards.

[0003] During normal drainage, the existing chest drainage device drains the drainage fluid into the three capacity chambers in sequence. However, once the bottle is tilted, the drainage fluid will flow into each capacity chamber at will, resulting in the inability to accurately record the drainage volume. In addition, the connecting tube and the drainage tube need to be installed by medical staff before use, which increases the workload of nursing staff and easily contaminates the sterile environment of the device. In clinical applications, it is found that when patients and their families move the water seal bottle, they ignore the hanging device and directly carry the connecting tube, which easily causes the connecting tube to fall off. At the same time, the drainage tube and the chest tube are fixed to each other by a connector, and there are two connections, which increases the risk of the tube slipping. When the patient's chest pressure is too high, the physiological saline at the water seal cavity will be attracted to the effusion cavity, resulting in the inability to accurately record the drainage volume.
