In the above structure, through the provided main body 1, slide plate 9, and positioning pin 15 structure, the user continues to pull the pull rod 3 after extracting the sputum from the patient's throat, so that the pull rod 3 drives the slide plate 9 to move upward, and in this process, after the sputum is extracted, the positioning pin 15 will be plugged into the positioning hole 6. Even after the user takes the sleeve 5 out of the patient's mouth, the sputum will continue to stay in the liquid collection tube 4 due to the negative pressure, and the medical staff can provide emergency treatment to the patient, and can centrally process the sputum after the treatment, thereby achieving the effect of emergency treatment.

In a preferred embodiment: a circular hole is opened on the inner wall of the second mounting groove 13, and the diameter of the circular hole is equal to the diameter of the positioning hole 6 and the positioning pin 15, and a limiting ring is fixedly assembled on the outer wall of the positioning pin 15, and the diameter of the limiting ring is 1 cm larger than the diameter of the second retaining spring 14 and the circular hole, respectively.

In the above structure, by setting the circular hole, the positioning hole 6 and the positioning pin 15 structure, the slide plate 9 can maintain the air pressure in the sputum suction device at a fixed state by using the cooperation of the positioning pin 15 and the positioning hole 6 after continuous rising, so that the sputum is adsorbed and always stays in the sputum suction device, which is convenient for the user to directly perform rescue operations after extracting the sputum and avoids the leakage of sputum. In addition, with the elasticity of the spring 8, the user can quickly recover the sputum by pressing the positioning pin 15, which is convenient for the user to quickly take out the sputum in the collection tube 4 for treatment, thereby improving the user's working efficiency.

In a preferred embodiment, a sliding hole is formed on the outer wall of the slide plate 9 , and the diameter of the sliding hole is equal to the diameter of the straight rod 7 , and the bottom of the spring 8 overlaps the top of the slide plate 9 .

In the above structure, by setting the straight rod 7 and spring 8 structure, the slide plate 9 is always limited by the straight rod 7 during the movement and rises and falls vertically, thereby improving the stability of the slide plate 9. At the same time, the thrust applied by the spring 8 to the slide plate 9 can facilitate the user to quickly remove the sputum in the collection tube 4, thereby improving the user's maintenance efficiency of the sputum suction device and the efficiency of handling sputum.

In a preferred embodiment: a blind hole is opened at one end of the sleeve 5 located on the inner wall of the collecting pipe 4, and the diameter of the blind hole is equal to the diameter of the bayonet 12. The sleeve 5 is fixedly connected to the inner wall of the collecting pipe 4 through the blind hole and the bayonet 12.

In the above structure, the blind hole is set to ensure that the sleeve 5 will not separate from the collecting tube 4 after the pin 12 is fixed to the sleeve 5. At the same time, the activity space of the blind hole will not allow the pin 12 to extend into the collecting tube 4, thereby avoiding contamination of the pin 12 by sputum during the suction process, thereby eliminating the need for the user to clean and disinfect it, reducing the maintenance cost and time required for the sputum suction device.

In a preferred embodiment: a slide groove is provided on the inner wall of the main body 1, and the outer wall of the limit block 16 is slidably connected to the outer wall of the slide groove, the outer wall of the slide plate 9 is slidably connected to the inner wall of the main body 1, and a rubber sealing ring is fixedly installed on the bottom of the slide plate 9, and the rubber sealing ring is tightly fitted to the inner wall of the main body 1.

In the above structure, the slide groove structure is set up in cooperation with the positioning pin 15 to limit the slide plate 9, so as to achieve the effect of improving the stability of the slide plate 9 during movement. The rubber sealing ring can ensure that the slide plate 9 can change the pressure during movement to ensure that the sputum in the patient's throat can be sucked into the collecting tube 4, thereby achieving the effect of sputum suction and avoiding suffocation of the patient.

In a preferred embodiment, the number of the positioning pins 15 is four, and the four positioning pins 15 are evenly distributed along the outer wall of the slide plate 9, and the slide plate 9 is made of galvanized iron metal.

In the above structure, the four positioning pins 15 are set up so that the four sides of the slide plate 9 can be limited, and it can also ensure that the slide plate 9 cannot tilt when the spring 8 applies thrust to the slide plate 9, further improving the stability of the slide plate 9 during movement.

In a preferred embodiment: a mounting hole is provided at the bottom of the body 1 , and the inner wall of the mounting hole is fixedly assembled with the outer wall of the liquid collecting pipe 4 .

In the above structure, through the setting of the mounting hole structure, the operator can quickly install the liquid collecting tube 4 in the main body 1 when assembling the suction pump, which is convenient for the medical staff to install the sleeve 5 in the liquid collecting tube 4, and the clamping structure has the effect of facilitating disassembly and assembly, thereby improving the efficiency of medical staff in replacing the sleeve 5.

Working principle: first, after the user assembles the sputum suction device, he can directly put the sleeve 5 into the patient's mouth, and then pull the pull rod 3, so that the slide plate 9 is driven by the pull rod 3 and slides along the outer wall of the straight rod 7, and at the same time compresses the spring 8, so that the rubber sealing ring and the body 1 have an adsorption effect on the patient's mouth, and then the sputum enters the liquid collecting tube 4 through the sleeve 5. After continuous pulling, the position of the positioning pin 15 coincides with the positioning hole 6, and the positioning pin 15 is pushed to be plugged into the positioning hole 6 under the action of the retaining spring 14. At this time, the pull rod 3 is fixed. After the sputum suction operation is completed, the user can directly put the sputum suction device aside and directly perform the treatment operation on the patient. After the treatment is completed, pick up the sputum suction device and align the sleeve 5 with the sputum collecting bucket. By pressing the positioning pin 15, the spring 8 applies a thrust to the slide plate 9 to allow the sputum in the liquid collecting tube 4 to slide into the sputum collecting bucket, and then pull the pin 12 to make the sleeve 5 unable to be fixed. Remove the used sleeve 5, and then clean and disinfect the liquid collecting tube 4 and the rubber sealing ring. Finally, replace the sleeve 5 with a new one through the same steps as above.
