[0002] Esophageal anastomotic fistula refers to the leakage of the anastomosis after esophageal surgery, especially after esophagectomy, esophageal cancer or gastroesophageal connection surgery. It is a more serious complication of esophageal surgery and may lead to postoperative infection, malnutrition, pneumothorax and other problems. During treatment, it is necessary to use a negative pressure tube to extract impurities such as wound exudate and nasal secretions. The existing negative pressure tube still has certain defects when used, such as;

[0003] When treating esophageal anastomotic fistula with existing technology, wound exudate is mixed with nasal secretions. The thick nasal mucus remaining after the water is separated is easily blocked and cannot be extracted, causing wound exudate to flow out of the gap between the negative pressure material and the inner wall of the wound, resulting in poor negative pressure suction treatment effect.
