When in use, the lid 2 is screwed on the top of the sputum suction tank 1, and then the negative pressure device is connected through the negative pressure pipe 3, and the lower end of the sputum suction pipe 6 is fixed in the through hole at the bottom of the humidification tank 5 through the sealing ring. At the same time, the humidification tank 5 is installed on the right side of the top of the lid 2 and inserted into the sputum suction tank 1, and sterile water is filled into the humidification tank 5 from the through hole at the top of the humidification tank 5. After the sputum suction pipe 6 is moistened, the sputum suction pipe 6 is pulled out from the through hole at the top of the humidification tank 5 and inserted into the airway, and then the negative pressure device connected to the negative pressure pipe 3 realizes that the sputum suction pipe 6 smoothly sucks out the secretions in the airway into the sputum suction tank 1, relieves airway obstruction, and restores the patency of breathing.

[0027] like Figure 3As shown, the humidification tank 5 also includes a control element 7 and a heating element 8, the control element 7 is installed on the front side of the top of the humidification tank 5, the heating element 8 is installed on the rear side of the top of the humidification tank 5, the control element 7 is electrically connected to the heating element 8, a check valve 9 is installed on the top of the sputum suction pipe 6, a suction head 10 is installed on the top of the check valve 9, the suction head 10 is made of a flexible material, and an annular pressure sensor 11 is installed on the top of the suction head 10, the pressure sensor 11 is electrically connected to the control element 7, when in use, the heating element 8 is adjusted by the control element 7 to heat the sterile water in the humidification tank 5, the sputum suction pipe 6 in the humidification tank 5 is humidified by the heated sterile water, and the external dry air attached to the sputum suction pipe 6 when the sputum suction pipe 6 is inserted into the respiratory tract is reduced. 6 can reduce the stimulation to the respiratory mucosa, and adjust the humidification degree as needed to adapt to the specific conditions of different patients. The heating element 8 provides a preheating option, so that the suction pipe 6, the check valve 9 and the suction head 10 can reach a suitable working temperature, reduce the stimulation to the respiratory tract and further protect the mucosa. When the suction pipe 6 is inserted into the respiratory tract for suction, the insertion force of the suction pipe 6 can be adjusted through the pressure sensor 11 on the suction head 10, which can effectively prevent the patient from being injured due to excessive pressure during the insertion of the suction pipe 6, and ensure that the suction head 10 efficiently and completely absorbs the sputum in the respiratory tract. At the same time, the check valve 9 is used to prevent the inhaled sputum from flowing back, thereby improving the safety and comfort of the treatment, thereby reducing the discomfort of insertion and improving the patient's willingness to use.

[0028] like Figure 2 , Figure 4 and Figure 5As shown, a baffle 12 is slidably installed on the left side of the top of the humidification tank 5, a handle 13 is installed on the left side of the top of the baffle 12, a limiter 14 is installed between the constant pressure hole 4 on the top of the cover 2 and the humidification tank 5, a limit plate 15 is slidably installed in the limiter 14, a slot is provided in the middle of the right side of the limit plate 15, an elastic rubber 16 is installed on the bottom left side of the limit plate 15, the shape of the elastic rubber 16 is adapted to the shape of the constant pressure hole 4, and the limit plate 1 5 is provided with a dustproof net 17 in the middle. When the electric sputum suction device is stored after use, the limit plate 15 is pushed to the right, and the limit plate 15 moves to the right until the elastic rubber 16 is engaged in the constant pressure hole 4 of the cover 2, and then the constant pressure hole 4 is sealed by the elastic rubber 16. After the sputum suction pipe 6, the check valve 9 and the suction head 10 are stored in the humidification tank 5, the limit plate 15 pushes the baffle plate 12 to move to the right to seal the through hole on the top of the humidification tank 5, thereby achieving the sputum suction tank 1. The humidifier 5 is sealed to prevent external pollution. When it needs to be used, the handle 13 is used to rotate the humidifier tank 5 so that the baffle 12 is located on the left side of the humidifier tank 5. Then, the baffle 12 is moved to the left so that the left side of the baffle 12 is clamped in the groove on the right side of the limiting plate 15 to fix the humidifier tank 5. At the same time, the handle 13 is continued to be pushed to the left. The baffle 12 is pushed to the left by the handle 13, and the baffle 12 is pushed to the left, thereby pushing the limiting plate 15 to move to the left, so that the elastic rubber 16 is disengaged from the constant pressure hole 4.

At the same time, continue to push the handle 13 to the left, and push the baffle 12 to the left through the handle 13. The baffle 12 is pushed to the left and then pushes the limit plate 15 to move to the left, so that the elastic rubber 16 is disengaged from the constant pressure hole 4. At this time, the dustproof net 17 is located at the top of the constant pressure hole 4 to prevent dust from clogging the constant pressure hole 4 during use. Continue to push the handle 13 to the left so that the baffle 12 does not block the through hole at the top of the humidification tank 5. At this time, the heating element 8 is adjusted by the control element 7 to heat the sterile water in the humidification tank 5, and the sputum suction pipe 6 in the humidification tank 5 is humidified by the heated sterile water to reduce sputum suction. When the pipe 6 is inserted into the respiratory tract, the external dry air adheres to the sputum suction pipe 6 to stimulate the respiratory mucosa. At the same time, the humidification degree is adjusted as needed to adapt to the specific conditions of different patients. The heating element 8 provides a preheating option, so that the sputum suction pipe 6, the check valve 9 and the suction head 10 can reach a suitable working temperature, reduce the stimulation to the respiratory tract and further protect the mucosa. When the sputum suction pipe 6 is inserted into the respiratory tract for suction, the insertion force of the sputum suction pipe 6 can be adjusted through the pressure sensor 11 on the suction head 10, and then the sputum suction pipe 6 is realized through the negative pressure device connected to the negative pressure pipe 3. The tube 6 smoothly sucks out the secretions in the airway into the sputum suction cup 1, relieves airway obstruction, and restores the patency of breathing. When the electric sputum suction device is stored after use, the limit plate 15 is pushed to the right, and the limit plate 15 moves to the right until the elastic rubber 16 is engaged in the constant pressure hole 4 of the cover 2, and then the constant pressure hole 4 is sealed by the elastic rubber 16. After the sputum suction pipe 6, the check valve 9 and the suction head 10 are stored in the humidification tank 5, the limit plate 15 pushes the baffle 12 to the right to move to the right to seal the through hole at the top of the humidification tank 5, thereby realizing the sealing of the sputum suction cup 1 to prevent external contamination.
