An esophageal occlusion device for preventing reflux as set forth in claim 4, wherein: the cuff outer diameter control structure further comprises a positioning clamp which can effectively position the adjusting wire after the sliding sleeve is adjusted to a required position, and the positioning clamp is clamped on the adjusting wire.
7. An esophageal occlusion device for preventing reflux as set forth in claim 2, wherein: the esophagus blocking device for preventing reflux further comprises a high-definition camera shooting structure, wherein the high-definition camera shooting structure can visually observe the inner condition of the esophagus of a patient when a medical staff inserts the gastrointestinal decompression drainage tube body into the intestines and stomach of the patient.
8. An esophageal occlusion device for preventing reflux as set forth in claim 7, wherein: the high-definition camera structure comprises
The medical staff can intuitively observe the condition inside the esophagus of the patient in the process of inserting the gastrointestinal decompression drainage tube body into the intestines and stomach of the patient, and the high-definition camera is arranged on the gastrointestinal decompression drainage tube body and is positioned between the cuff and the front end of the gastrointestinal decompression drainage tube body;
- -high definition digtal camera connector, high definition digtal camera connector is connected with high definition digtal camera through the signal connection line, the signal connection line sets up in the connecting wire passageway of seting up at intestines and stomach decompression drainage tube body lateral wall, high definition digtal camera connector peg graft on the display that can make medical personnel audio-visual observation patient's esophagus inside condition.
9. An esophageal occlusion device for preventing reflux as set forth in claim 1, wherein: the outer wall of the gastrointestinal decompression drainage tube body is provided with scales along the axial direction of the outer wall, so that medical staff can intuitively observe the length of the gastrointestinal decompression drainage tube body inserted into the esophagus of a patient.
10. A method of operating an esophageal occlusion device for preventing regurgitation, characterized in that the method of operating is based on an esophageal occlusion device for preventing regurgitation according to any of claims 1-9, comprising the steps of:
a first step of: medical staff inserts the front end of the gastrointestinal decompression drainage tube body into the esophagus and the stomach of a patient through the mouth and the nasal cavity of the patient;
and a second step of: medical staff observe the insertion position of the front end of the gastrointestinal decompression drainage tube body and the condition inside the esophagus in the insertion process through observing the high-definition camera;
and a third step of: after confirming that the front end of the gastrointestinal decompression drainage tube body is inserted into the intestines and stomach of a patient, medical staff controls an inflator pump to work through a controller, the inflator pump fills gas into a cuff through an inflation tube, and the cuff is gradually inflated to be contacted with the esophagus of the patient after being inflated until the pressure between the outer wall of the cuff and the esophagus of the patient reaches a set pressure value;
fourth step: after the pressure between the cuff and the esophagus of the patient reaches a set pressure value, the pressure sensor sends a pressure signal to the controller, the controller controls the inflator pump to stop working, and then the medical staff performs relevant operation on the patient.
