The invention discloses a handy sputum suction device, which comprises a piston-type negative pressure cylinder, wherein the piston-type negative pressure cylinder comprises a connecting plate, one side of the connecting plate is fixedly provided with a negative pressure cylinder, and a piston is slidably connected in the negative pressure cylinder. One end of the negative pressure cylinder away from the connecting plate is communicated with a sputum collecting part, and the sputum collecting part is communicated with a sputum suction tube. A driving part is arranged on one side of the connecting plate far away from the negative pressure cylinder, and the driving part is in transmission connection with the piston. According to the invention, the piston-type negative pressure cylinder is driven by the driving part, so that medical staff only need one hand to keep the position of the sputum suction hose motionless, and the sputum suction work can be realized, and the operation is convenient. Moreover, the piston of the piston-type negative pressure cylinder can suck sputum in the push-pull process, with smooth movement and improved sputum suction efficiency. Furthermore, by setting the sputum collecting part, the backflow of sputum in the sputum suction device can be avoided. Moreover, by dividing the sputum suction tube into two channels, the sputum blocked by the sputum suction tube can be cleaned in time, which greatly improves the effect and progress of sputum suction treatment for patients. 30 3 22 B 37 36 35 2 5 8 1 17 15 16 C / 31 / 32 23 6i \ 7 \ 4 A 18 \19 \21\ 20 Fig. 1 A schematic structural diagram of the sputum suction device of the present invention.
