Description

Closed thoracic drainage device

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a closed thoracic drainage device.

Background

Closed thoracic drainage is a common clinical operation in thoracic surgery, and is an effective method for treating empyema, traumatic hemothorax, pneumothorax and spontaneous pneumothorax. Normally, the chest cavity of a human body is in a negative pressure state, but when the chest wall is damaged due to operations, trauma and the like or pulmonary alveoli at the edges of the lungs are ruptured due to long-term pulmonary diseases such as tuberculosis, emphysema, bronchiectasis and the like, air can enter the chest cavity, so that the negative pressure in the chest cavity disappears, and the lungs lose respiratory function due to the fact that the lung is compressed to be small. Therefore, closed thoracic drainage techniques are required to drain gases and fluids from the thoracic cavity. The thoracic drainage device generally adopts a method of placing a drainage tube into an incision after a thoracic incision by an operation or placing the drainage tube into a thoracic cavity by a puncture method, and the following problems exist in the conventional thoracic closed drainage device for draining gas and liquid in the thoracic cavity to the outside of the body:

the existing thoracic cavity closed drainage device is used by all units and has a single cavity, a double cavity and a triple cavity, but the thoracic cavity closed drainage device can only be fixed at a certain position for use, and is poor in portability;

in addition, the existing thoracic closed drainage device is large in size, and the reason is that the drainage bottle is combined with the thoracic bottle, and if the drainage device is not combined with the thoracic bottle, the sealing performance of the device is poor;
