AI Technical Summary
The tip of the existing balloon-type jejunal feeding tube is prone to puncturing the anastomosis, and the balloon is easily damaged, resulting in high usage costs and no alternative fixation solution.
A modified balloon jejunal feeding tube is designed, featuring first and second lumens arranged horizontally side by side, serving as liquid and gas channels respectively. A flat, smooth balloon is provided at the end of each lumen to provide a backup fixation solution. The tube is made of soft medical materials such as silicone or polyurethane.
This allows for smoother placement of the feeding tube under patient anesthesia without puncturing the anastomosis, extending its service life and reducing costs.

[0002] The jejunum nutrition tube is a catheter inserted into the jejunum part, one end of which is inserted into the nasal cavity, passes through the pharynx, esophagus and stomach, and finally reaches the jejunum, and the main function thereof is to directly deliver the nutrient substances into the jejunum to ensure the nutrient supply of the patient when the patient cannot take food orally or the oral food cannot meet the body's nutrient demand. For some patients suffering from digestive system diseases, such as severe pancreatitis, gastrointestinal fistula, short bowel syndrome and the like, and some patients in a coma state, patients with difficulty in swallowing or patients after a major operation, the jejunum nutrition tube is an important treatment means. CN202844157U discloses an air bag type double-lumen duodenum or jejunum nutrition tube, a nutrition liquid injection port is arranged on the upper head of the nutrition tube, and an opening is arranged on the lower part, an air injection tube is arranged on the nutrition tube in parallel, an air injection port is arranged on the upper head of the air injection tube, and an air bag is arranged on the lower head of the air injection tube, when in use, the air bag type double-lumen duodenum or jejunum nutrition tube is placed into the duodenum or jejunum under the gastroscope, a certain amount of air is injected into the air bag, the nutrition tube can be fixed with the duodenum or jejunum wall and cannot be taken out with the gastroscope, and the air in the air bag is extracted after the gastroscope is taken out. As can be seen from the drawings, the nutrition tube in the patent has a relatively sharp tip, the tip is easy to cause a relatively large pressure on the wall around the anastomotic stoma, the anastomotic stoma is easy to be poked, and the anastomotic stoma fistula is caused; in addition, the air bag in the patent has only one, and once the air bag is broken, the whole instrument cannot be used, and the use cost is high.
