The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0036] In the related art, for patients with weak expectoration, a sputum suction tube is generally used to help them expel sputum. In order to quickly expel sputum, visual sputum suction tubes have appeared in the prior art. In order to improve the visualization effect, the prior art adds an optical fiber in the sputum suction tube to provide illumination at the sputum suction port during the sputum suction process.

[0037] However, during the sputum suction process, the sputum suction tube will be bent, causing the optical fiber to also be bent. During the bending of the optical fiber, the refraction effect inside the optical fiber and the position of the optical fiber head will change, causing unstable illumination.

By arranging the illumination module outside the image acquisition module and connecting the second connecting line of the illumination module through the connecting joint, the image acquisition module and the illumination module can be powered simultaneously through the connecting joint, thereby reducing the influence of the bending of the sputum suction tube on the illumination effect; in addition, by arranging the illumination module outside the image acquisition module, the two are relatively stationary, thereby reducing the influence of the relative movement between the two on the visualization effect. By reducing the influence of the bending of the sputum suction tube on the illumination effect and reducing the influence of the relative movement between the two on the visualization effect, the stability of the illumination effect can be improved.
