A driving assembly is provided at the lower right side of the fixed seat 1. When the driving assembly is operated, the driving assembly can drive the piston block 102 to move up and down; the driving assembly includes a u-shaped plate 106, an L-shaped rod 107 and an electric screw 108. Three u-shaped plates 106 are evenly spaced and embedded and fixedly connected at the lower right side of the fixed seat 1.

The L-shaped rod 107 slides through the left side of the hollow cylinder 101 and is fixedly connected to the bottom of the piston block 102. An electric screw 108 is installed on the inner side of the u-shaped plate 106, and the electric screw 108 is threadedly connected to the left side of the L-shaped rod 107.

[0034] Initially, the liquid cylinder 10 is filled with an appropriate amount of disinfectant. First, the middle connector 7 is pulled out from the hollow cylinder 101, and then the disposable sputum suction tube is put on the middle connector 7. Due to the telescopic effect of the telescopic bellows 6, the connector 7 can be pulled at will to drive the disposable sputum suction tube to move and insert into the patient's respiratory tract. The control panel 2 is pressed to control the air pressure sensor 82 and the audio sensor 83 to start through the control module. The AI ​​module in the control panel 2 monitors the air pressure in the respiratory tract through the air pressure sensor 82, and the audio sensor 83 monitors the sputum sound in the respiratory tract. When the AI ​​module in the control panel 2 detects that the air pressure and sputum sound in the respiratory tract have changed and sputum suction is required through the air pressure sensor 82 and the audio sensor 83, the control panel 2 The AI ​​module of the control module controls the cylinder 44 to start, and the telescopic rod of the cylinder 44 shortens and drives the L-shaped piston rod 41 to move downward. The downward movement of the L-shaped piston rod 41 makes the cylinder body 4 in a negative pressure state, and the cylinder body 4 makes the middle telescopic bellows 6 in a negative pressure state, and the middle telescopic bellows 6 makes the disposable sputum suction tube in a negative pressure state, and the disposable sputum suction tube draws the sputum in the patient's respiratory tract into the middle telescopic bellows 6 through the middle connector 7, and the sputum in the middle telescopic bellows 6 is discharged into the cylinder 46 through the ball valve 81, and the sputum in the cylinder 46 is discharged into the cylinder body 4 through the one-way extraction pipe 45 for collection. When the sputum in the patient's respiratory tract is sucked away, the AI ​​module in the control panel 2 monitors the patient's respiratory tract through the air pressure sensor 82 and the audio sensor 83. When it is detected that the air pressure and sound in the patient's respiratory tract have returned to normal, the AI ​​module in the control panel 2 controls the cylinder 44 through the control module to drive the L-shaped piston rod 41 to move upward and reset. The L-shaped piston rod 41 resets to push the sputum in the cylinder body 4 into the one-way discharge pipe 42, and the one-way discharge pipe 42 discharges the sputum. In this way, the AI ​​module in the control panel 2 can be used to determine when to start suctioning, without the need for medical staff to make a judgment, thereby reducing the work pressure of medical staff. Then the medical staff pulls out the disposable suction tube from the patient's respiratory tract, unplugs the disposable suction tube from the middle connector 7 and throws it into the trash can, inserts the middle connector 7 back into the middle hollow cylinder 101, and inserts the middle connector 7 into the middle conducting tube 104, and then there is no need to wait for the disposable suction tube to be removed from the patient's respiratory tract. The other connector 7 is pulled out to use the unused telescopic bellows 6, and the control panel 2 is pressed to control the drive motor 9 to start through the control module. The drive motor 9 drives the ball valve 81 to rotate 120 degrees, so that the ball valve 81 is connected with the telescopic bellows 6 in use, and a new disposable sputum suction tube is put on the pulled out connector 7 to continue to suction the next patient. At the same time, the electric screw 108 corresponding to the used telescopic bellows 6 is started, and the electric screw 108 drives the L-shaped rod 107 to move up and down, and the L-shaped rod 107 drives the piston block 102 to move up and down. When the piston block 102 moves downward, the piston block 102 draws the disinfectant in the liquid cylinder 10 into the hollow cylinder 101 through the liquid inlet pipe 105. When the piston block 102 moves upward,The piston block 102 pushes the disinfectant in the hollow cylinder 101 into the guide tube 104, and the disinfectant in the guide tube 104 is discharged into the connector 7, and the disinfectant disinfects the connector 7, and the disinfectant in the connector 7 is discharged into the telescopic bellows 6 after use, and the disinfectant disinfects the telescopic bellows 6 after use, and the disinfectant after the disinfection of the telescopic bellows 6 is discharged into the cylinder 46 through the ball valve 81, and the disinfectant in the cylinder 46 is discharged into the cylinder 4 through the one-way extraction pipe 45, and the disinfectant in the cylinder 4 is discharged through the one-way discharge pipe 42. When the disinfection of the telescopic bellows 6 after use is completed, the electric screw 108 is closed, and the L-shaped rod 107 stops driving the piston block 102 to move up and down, and the disinfectant stops being discharged into the connector 7 and the telescopic bellows 6. In this way, after one telescopic bellows 6 is used, another unused telescopic bellows 6 can be used, and sputum can be sucked while disinfecting, without interrupting the sputum suction treatment of the next patient, thereby improving the continuity of sputum suction and the overall work efficiency. When all patients have completed the suction, the control panel 2 is pressed to control the air pressure sensor 82 and the audio sensor 83 to be turned off through the control module.

When the suction pressure of sputum suction is adjusted to the appropriate suction pressure for the patient, the servo motor 113 is turned off, and then the L-shaped piston rod 41 moves downward to make the cylinder 4 in a negative pressure state, the disposable sputum suction tube draws the sputum into the telescopic bellows 6 through the connector 7, and then the sputum is discharged into the cylinder through the ball valve 81, and the sputum in the cylinder passes through the four-hole plate 11 and the four-hole circular plate 114 and is discharged into the one-way extraction pipe 45, and the one-way extraction pipe 45 discharges the sputum into the cylinder 4 for collection.

The disinfectant in the one-way connecting pipe 123 is discharged into the annular nozzle 122. The annular nozzle 122 sprays the disinfectant on the annular brush 121 and the connector 7 after use. At the same time, the L-shaped rod 107 also drives the rack 127 to move upward. The rack 127 moves upward to drive the guide The guide gear 128 rotates forward, the guide gear 128 rotates forward to drive the screw rod 125 to rotate, the screw rod 125 rotates to drive the trigger frame 126 to move leftward, the trigger frame 126 moves leftward and breaks contact with the fixed frame 129, due to the action of the tension spring 1212, the guide rod 1211 moves downward to drive the annular brush 121 to move downward, the annular brush 121 moves downward to clean and disinfect the used connector 7 with disinfectant, and the annular brush 121 can also remove impurities on the connector 7 The disinfectant after cleaning and disinfection falls onto the fixed block 103. Since the top of the fixed block 103 is an inclined surface, the disinfectant is discharged into the drain pipe 1231 through the fixed block 103. The drain pipe 1231 discharges the disinfectant for collection. When the L-shaped rod 107 moves downward to drive the piston block 102 to move downward, the disinfectant stops being discharged into the one-way connecting pipe 123. The L-shaped rod 107 drives the rack 127 to move downward and reset. The rack 127 drives the guide gear 128 to reverse. The guide gear 128 reverses and drives the screw rod 125 to reverse. The screw rod 125 reverses and drives the trigger frame 126 to move right and reset. The trigger frame 126 resets and drives the fixed frame 129 to move upward and reset. The fixed frame 129 resets and drives the annular brush 121 to move upward and reset. The annular brush 121 resets and drives the guide rod 1211 to move upward and reset. The tension spring 1212 is stretched, and this is repeated, so that the annular brush 121 can move up and down to disinfect the outer wall of the connector 7 through the disinfectant. When the L-shaped rod 107 stops moving, the L-shaped rod 107 stops driving the rack 127 to stop. In this way, it is possible to prevent the outer wall of the connector 7 from being attached with impurities and bacteria to affect subsequent use, thereby ensuring that the connector 7 is clean.
