Description

TECHNICAL FIELD

[0001] The present application relates to a chest drainage tube fixing device. BACKGROUND

[0002] As a treatment method, closed thoracic drainage is widely used in the drainage of hemopneumothorax, pyothorax and post-thoracotomy, and plays an important role in the treatment of diseases.

[0003] The drainage tube fixing device is used to prevent the drainage tube from falling off from the patient's chest position and to increase the stability of the drainage tube. However, the liquid flow in the drainage tube cannot be predicted, and the size of the liquid flow in the tube changes in real time, so that the clamping tightness between the fixing device and the drainage tube cannot be controlled. If the clamping tightness is set according to the maximum flow, when the flow in the drainage tube is small, the drainage tube will be deflated, and the fixing device will be easily separated from the drainage tube. If the clamping tightness is set according to the minimum flow, when the flow in the drainage tube increases, the clamping setting will limit the work of the drainage tube, affecting the drainage efficiency of the drainage tube. In addition, the fixing device pulls the drainage tube at the fixed position, which may change the insertion angle of the drainage tube, causing secondary injury to the patient. If a fixing device is also provided at the insertion end of the drainage tube, it will not only increase the complexity of the installation of the fixing device, but also make it inconvenient to adjust the angle of the drainage tube after installation.
