The sputum suction head 8 can be arranged on the right end of the sputum suction tube 7 through a threaded connection, or can be set on the right end of the sputum suction tube 7 through a plug-in connection. Because the sputum suction head 8 can be disassembled, it can be a disposable product, so that different patients can easily replace different sputum suction heads 8 for use, and avoid cross-infection.

When using the vacuum pump 5 to control the suction process, keep the plunger 2 at the right end of the negative pressure cylinder 1, connect the vacuum tube 51 and the vacuum pump 5, and open the vacuum valve 42, and the vacuum pump 5 will work to make the sputum storage cylinder 4 Negative pressure is formed inside; then, plug the sputum suction head 8 on the patient's nostril, and open the sputum suction valve 71, under the effect of negative pressure, the sputum in the nasal cavity or sinuses will pass through the sputum suction head 8 and the sputum suction tube 7 Flow into the sputum storage tube body 4. When stopping sputum suction, close the vacuum pump 5 and pull the sputum suction head 8 away from the nostril, and the pressure in the sputum storage cylinder 4 will return to normal.

When the suction process is controlled by manually operating the plunger 2, the vacuum valve 42 is closed, and the push rod 3 is pulled out to the left through the handle 31, so that the plunger 2 moves to the left, thereby increasing the negative pressure of the cylinder 1 located at the plunger. The volume of the chamber on the right side of 2 makes a negative pressure in the sputum storage cylinder 4; then, put the sputum suction head 8 on the patient's nostril, and open the sputum suction valve 71, under the effect of negative pressure, the nasal cavity or The sputum in the nasal sinuses flows into the sputum storage barrel 4 through the sputum suction head 8 and the sputum suction tube 7 . When stopping sputum suction, pull the sputum suction head 8 away from the nostril, and push the push rod 3 to the right to reset the plunger 2 . The chamber on the left side of the plunger 2 of the negative pressure cylinder body 1 can be communicated with the outside world, it can be provided with an air hole in addition, or it can be communicated with the outside world through the hole where the push rod 3 is located, so as to keep the negative pressure cylinder The air pressure in the chamber on the left side of the plunger 2 of the body 1 is the same as the atmospheric pressure, so as to effectively reduce the pulling force required to pull out the push rod 3 . The chamber on the left side of the plunger 2 of the negative pressure cylinder body 1 can also be isolated from the outside world, although when pulling out the push rod 3, the time required to pull out the push rod 3 will be increased due to the increase in the air pressure of the chamber on the left side. However, it can reduce the thrust when pushing the push rod 3 to the right under the effect of air pressure difference, so as to facilitate the reset of the plunger 2.

The utility model can control the sputum suction process through the vacuum pump 5 or the moving plunger 2. Its structure is simple, easy to carry, and the patient can use it at home without going to the hospital for sputum suction, and one of them can be selected when using it at home. There are several ways to control the suction process, which is very convenient to use. And when the patient goes out, can decide whether to carry vacuum pump 5 according to needs, when carry-on luggage is more inconvenient to carry vacuum pump 5, can stay vacuum pump 5 at home, thereby control the sputum suction process by manually moving plunger 2 and get final product. In addition, the sputum storage cylinder 4 of the present invention can be disassembled and replaced or cleaned, and the sputum suction head 8 can also be disassembled and replaced to facilitate the use of different patients and avoid cross-infection.

The sputum storage cylinder 4 of the present utility model can also be a disposable article, but what the utility model adopts is the sputum storage cylinder 4 that can be reused by cleaning. And preferably, the lower half of the inner wall surface of the sputum storage cylinder body 4 is provided with a sponge pad 43 in a detachable manner, and the sponge pad 43 can be directly laid on the lower half of the sputum storage cylinder body 4, or can be made by The way of sticking or clamping is arranged on the lower half of the sputum storage cylinder 4 . The sponge pad 43 is a one-time product. The sputum is absorbed by the sponge pad 43. After the suction is completed, the sponge pad 43 is taken out and cleaned up, and replaced with a new sponge pad 43 to reduce residues in the sputum storage container. The sputum in the body 4, thereby reducing the number of times to clean the sputum storage cylinder 4 and reducing the difficulty of cleaning. Especially when going out for use and cleaning is inconvenient, setting the sponge pad 43 can further facilitate the travel of the sputum suction device.

Further, continuing to refer to FIG. 1 , a baffle 9 is movably sleeved on the sputum suction tube 7 , and the baffle 9 is in the shape of a trumpet with a larger right end. When sucking sputum, block the shield 9 in front of the patient's mouth and nose to prevent the sputum from splashing around when the patient sneezes or holds the sputum suction tube unstable during the sputum suction process, thereby avoiding the sputum from splashing on others and ensuring the use Hygiene of the process. Further preferably, the left end of the baffle 9 is movably sleeved on the sputum suction tube 7 through a soft cover 91, and a soft rope 92 is arranged on the soft cover 91, and when the baffle 9 is moved to a suitable position, by tightening the soft Rope 92 just can fix the position of blocking cover 9, so that adjust.
