[0002] Gastric lavage machine is a common medical device, which is often used to rescue patients with food poisoning, poisoning and gastric lavage before surgery. In the existing gastric lavage machine, the sewage tank inside is controlled by a reversing device to control the inlet and outlet of liquid. Once the volume of the sucked foreign matter is large, it will jam the reversing device and affect its normal reversing work. After the reversing work fails, the contents in the stomach will not be discharged smoothly, and the clean water entering the stomach will not decrease, resulting in more and more contents in the stomach. At this time, it is necessary to perform a strong suction operation on the contents in the stomach.

[0003] At present, in order to achieve the effect of strong suction gastric lavage in clinical practice, a negative pressure suction bottle is usually hung on the gastric lavage machine for strong suction gastric lavage. However, this method not only requires manual operation each time, which is cumbersome to operate, but also is limited by the capacity of the suction bottle and can only perform 2-3 strong suction gastric lavage operations, and cannot meet the needs of continuous and unlimited strong suction gastric lavage. There are problems of poor effect and poor effectiveness of strong suction gastric lavage. Summary of the invention

[0004] The purpose of the present invention is to provide a gastric lavage machine with a strong suction function which has a scientific and reasonable structural design, is convenient to operate, has a good strong suction effect and is easy to implement.

The clamping tube mechanism includes a frame 26, a mounting seat 21, a motor 25, a reducer 24, a swing block, a strong suction drainage pipe 19 and a strong suction gastric tube 20.

[0034] The power supply is used to supply power to the clean water tank, sewage tank, strong suction tank, motor and reducer. A one-way valve connected to the clean water tank pipeline is arranged on the solenoid valve plate. A mounting seat is installed on the frame, and an axial hole is arranged in the middle of the mounting seat. The reducer and motor are installed in the frame, and the shaft of the reducer extends out of the axial hole to drive the swing of the pendulum block.
