[0032] The second segment 22 is frustoconical, and the diameter of the second segment 22 gradually decreases from the vicinity of the first segment 21 to the distance from the first segment 21. The second segment 22 comprises a connecting segment 221 for connecting with the first segment 21, and a tapered segment 222 arranged at the lower end of the connecting segment 221. In the embodiment shown, the outer diameter of the connecting segment 221 matches the inner diameter of the first segment 21 so as to be clamped at the lower end of the first segment 21. A sealing ring 223 is arranged on the outer periphery of the connecting segment 221, which can increase the sealing between the first segment 21 and the second segment 22. In other embodiments, the second segment 22 can also be connected with the first segment 21 by means of threaded connection or the like, as long as the detachability of the two can be achieved. However, compared with the threaded connection, the clamping mode makes the connection between the first segment 21 and the second segment 22 easier to clean, and thus is the preferred assembly mode. A protrusion 224 is arranged on the outer periphery of the connecting segment 221, which is located at the middle position of the connecting segment 221 and used to abut against the lower end surface of the first segment 21 when the connecting segment 221 is clamped on the first segment 21. The protrusion 224 divides the connecting segment 221 into two segments. The upper end of the tapered segment 222 matches the connecting segment 221 in diameter and communicates with the connecting segment 221, and the diameter of the tapered segment 222 gradually decreases from the upper end to the lower end. A cover 225 is detachably arranged at the opening of the lower end of the tapered segment 222. In the embodiment shown, the inner diameter of the cover 225 matches the outer diameter of the tapered segment 222 at the position corresponding to the opening, and the cover 225 can be clamped on the tapered segment 222. In other embodiments, the cover 225 can also be connected with the tapered segment 222 by means of threaded connection or the like, as long as the detachability of the two can be achieved. However, compared with the threaded connection, the clamping mode makes the connection between the tapered segment 222 and the cover 225 easier to clean, and thus is the preferred assembly mode. The diameter of the opening matches the diameter of the guide tube 27, and the axial dimension of the second segment 22 matches the distance between the end of the guide tube 27 and the end of the first segment 21 close to the second segment 22.

[0033] The working mode of one of the embodiments of the endoscopic handheld sputum aspirator is as follows: when in use, the end of the suction pipe 3 far away from the suction body 1 is inserted into the throat of a patient, the switch 19 is pressed to start the suction pump, the suction pump extracts the air in the collecting cylinder 2 to generate negative pressure, so that the sputum is sucked into the collecting cylinder 2 through the suction pipe 3, and in this process, the medical staff can observe the throat condition of the patient through the display screen 14 and timely adjust the position and depth of the suction pipe 3. The setting of the guide pipe 27 makes the entrance of the sputum into the collecting cylinder 2 lower, so that the sputum can be directly guided into the lower part of the collecting cylinder 2, avoiding that the sputum is sucked into the suction pump through the opening of the suction body 1 from the second guide groove 18 when the suction pump inhales. It is worth noting that the side surface of the collecting cylinder 2 can be provided with scale lines to facilitate the medical staff to know the amount of sputum sucked out, and the tapered design of the second part facilitates the medical staff to read the scale when the sputum is less, that is, a small amount of sputum can also have a height that can be read in the tapered second part, if the second part is designed in a cylindrical shape, the height of a small amount of sputum in it is very low, and it is difficult for the medical staff to read.

[0034] When the device needs to be cleaned, the suction pipe 3 can be detached from the suction body 1, but since the suction pipe 3 has a certain length, directly placing the suction pipe 3 in water for cleaning cannot make it completely clean. The end of the suction pipe 3 far away from the suction body 1 is inserted into the cleaning liquid, the switch 19 is pressed to start the suction pump, the suction pump sucks the cleaning liquid into the collecting cylinder 2 through the suction pipe 3, so that the cleaning liquid flows in the suction pipe 3 and carries away the dirt on the inner wall of the suction pipe 3. Then the collecting cylinder 2 can be rotated and taken off from the suction body 1 to clean the liquid in it. Please refer to Figure 7 When cleaning, the second segment 22 can be separated from the first segment 21, and the end cover 225 is taken off from the second segment 22, so that the second segment 22 is in the state that the tapered segment 222 is on top. The second segment 22 is inserted into the lower end of the first segment 21, at this time, the section of the connecting segment 221 between the convex edge 224 and the tapered segment 222 is clamped in the first segment 21, and the opening is engaged with the lower end of the guide pipe 27. The medical staff can invert the suction body 1, pour water into the guide pipe 27 from the opening of the tapered segment 222 to flush the guide pipe 27, and at the same time, the water enters the suction pipe 3 through the guide pipe 27 to flush the suction pipe 3. Such a setting can realize bidirectional cleaning of the suction pipe 3, making the cleaning more thorough and ensuring the cleanliness of the device. At the same time, the collecting cylinder 2 can also be detached for separate cleaning, and the collecting cylinder 2 can be detached into the first segment 21, the second segment 22 and the end cover 225, so that they can be cleaned respectively, so that there is no dirt remaining in the device.
