[0014] The present invention provides a visual medical device, having the following beneficial effects: (1) In this invention, the sputum aspirator and the sputum aspiration mask can be driven to move through the support frame and the moving seat. When the sputum aspiration mask aspirates sputum from the patient, pressing the elastic telescopic block downward can make the sputum aspiration mask fit more closely with the patient's mouth. At the same time, the push rod will push the nose clip to clamp the patient's nose, preventing air leakage from the nose when the sputum aspiration mask aspirates sputum from the mouth, which may affect the sputum aspiration effect. Meanwhile, when there is vomit in the patient's mouth, the sewage discharge plate and the liquid suction device will suck out the foreign matter vomited by the patient. When the sputum aspiration mask is working, the baffle will seal the sewage discharge plate, preventing the air inside the sputum aspiration mask from being discharged through the sewage discharge plate and affecting the sputum aspiration.

[0015] (2) In this invention, the support frame is unidirectionally limited by the fixed block and the rotating block, enabling automatic limiting when the support frame descends, which improves the speed of using the sputum aspiration mask. Meanwhile, when the patient needs to turn sideways to vomit, the staff steps on the foot pedal and the moving block moves downward, and the movable rod will push the turning board to rotate, making it easier for the patient to turn sideways to vomit. At the same time, when the turning board rotates, it will push the elastic piece and the bent rod to move, and the bent rod will push the moving board and the inclined block to move. The rotating board will release the upward movement of the support frame, preventing the support frame from affecting the patient's turning over when the patient turns over.

[0016] (3) In this invention, when the turning board rotates, it will push the arc rod and the piston plate to move. The piston plate will squeeze the air inside the cylinder and discharge it from the exhaust pipe. The baffle will block the exhaust pipe, making the exhaust pipe only slowly discharge the air inside the cylinder, so that the rotating board will drive the sputum aspiration mask to rotate slowly, preventing the rotating board from rotating quickly and hitting the staff. Meanwhile, when the turning board rotates, the cover plate will release the block on the exhaust pipe, enabling the rotating board to rotate quickly to avoid the slow rotation of the rotating board affecting the patient's turning over.

The elastic force of the first spring will drive the support frame 4 to move upward quickly; When the staff releases the suction mask 8, the elastic force of the scroll spring will drive the rotating plate 6 and the suction mask 8 to rotate. When the rotating plate 6 rotates, it will drive the arc rod 193 and the piston plate 192 to move into the cylinder 191. The piston plate 192 will squeeze the air inside the cylinder 191 and discharge it from the exhaust pipe 194. The cover plate 195 will block the exhaust pipe 194, so that the exhaust pipe 194 can only slowly discharge the air inside the cylinder 191. The cylinder 191 will reduce the rotation speed of the piston plate 192, the arc rod 193 and the rotating plate 6. At the same time, when the moving plate 181 moves, it will drive the telescopic rod 197 to move. When the telescopic rod 197 moves, it will drive the linkage rod 196 to move. When the linkage rod 196 moves, it will drive the cover plate 195 to move. When the cover plate 195 moves, it will drive the through hole to move.
