[0002] Nasogastric-intestinal tubes, nasogastric tubes and nasojejunal tubes are all commonly used feeding tubes in clinics, and are mainly used for nutritional supply of patients after esophageal cancer surgery, digestive tract tumor surgery and some patients who cannot eat orally due to diseases. However, during the enteral nutrition support process, due to the characteristics of the enteral nutrient solution being sticky, thick and concentrated, the characteristics of the nasogastric-intestinal tubes, nasogastric tubes and nasojejunal tubes being thin, long and soft, and the factors such as the untimely preventive flushing by medical staff, the nasogastric-intestinal tubes, nasogastric tubes or nasojejunal tubes are often blocked. And there are research reports that during the enteral nutrition support process, the tube blockage rate of nasojejunal tubes abroad is 6-10%, the tube blockage rate of gastric tubes abroad is 3%-7%, the tube blockage rate of nasojejunal tubes in China is 5-21%, and the tube blockage rate of nasogastric tubes in China is 3%-9%.
