Blocking drainage device for esophagogastric anastomotic leakage

Abstract

The invention discloses a blocking drainage device for esophagogastric anastomotic leakage. The blocking drainage device comprises a flexible air bag adopting a jacket structure, wherein the flexible air bag consists of an inner side wall and an outer side wall which are integrally sealed by a sealing face;the upper part and the lower part of the flexible air bag are expanded to form an upper expanded segment and a lower expanded segment; a drainage tube body penetrating the top of the upper expanded segment is arranged in the flexible air bag; the lower part of the drainage tube body outwardly penetrates the middle of the outer side wall of the flexible air bag; a first flexible sealing gasket is arranged in the position, corresponding to the drainage tube body, at the top of the upper extended part; an air inlet and outlet pipe with an air inlet and outlet valve is arranged on the first flexible sealing gasket in an upwardly extending manner; a second flexible sealing gasket is arranged in the position, corresponding to the drainage tube body, on the outer side wall of the flexible air bag; and metal sheets are embedded into the second flexible sealing gasket at intervals. The blocking drainage device has the following advantages: anastomotic leakage is blocked by the flexible air bag, so that tight blockage and high degree of comfort are realized; and cleaning treatment is performed on vomicae in the chest or the mediastinum of a patient through a flushing pipe and a draining pipe, and the treatment effect is effectively guaranteed.

Description

technical field [0001] The invention relates to medical auxiliary equipment, in particular to an occlusion and drainage device for esophagogastric anastomotic fistula. Background technique [0002] Esophagogastric anastomotic leakage is a serious complication after radical esophagectomy in thoracic surgery, which seriously affects the quality of life and survival of patients. According to the survey, the incidence rate of anastomotic leakage in the neck is about 9%, the incidence rate of anastomotic leakage in the chest is about 5%, and the mortality rate of anastomotic leakage is as high as 50-70%. After the patient has an esophagogastric anastomotic fistula, saliva and stomach contents continuously overflow from the fistula into the thoracic cavity or mediastinum, resulting in protracted thoracic or mediastinal infection, and the infection and consumption of the body seriously threaten the life of the patient. [0003] At present, the treatment methods for esophagogastric...

AI Technical Summary

Problems solved by technology

Conservative treatment often has insufficient drainage, nutritional disorders, and poor curative effect; secondary surgical operations are traumatic and risky, and many patients are difficult to tolerate and accept; interventional treatment is minimally invasive, low cost, good curative effect, and easy for patients to accept and tolerate

However, there is currently no medical device specially used to block the fistula and drain pus. During treatment, an esophageal stent is placed in the esophagus, the fistula is blocked with the stent, and then the pus in the pleural cavity or the pus in the mediastinum is treated. Drainage and Irrigation Therapy

Because the esophageal stent is placed in the esophagus, the foreign body sensation is strong; the stent is easy to shift and the fistula is not tightly sealed, which affects the treatment effect; and the stent must be removed within a short time (two months), otherwise it is easy to cause esophageal restenosis. further increase the patient's risk
