Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a gastric tube with an esophageal dilation balloon. Background Technology

[0002] A gastric tube is used in special circumstances to deliver necessary fluids and food to patients who cannot swallow. Gastric tubes are generally made of polyurethane or silicone. Depending on the material, polyurethane and silicone tubes should be replaced monthly. They come in various sizes and lengths. Gastric tubes are either orally or nasally tubes. Nasogastric tubes are prone to dislodgement and should be securely fastened to prevent repeated insertion and aspiration. They consist of the tubing, feeding port connector, tube clamp, and a cross-shaped cap. There are usually two feeding port connectors. The uppermost connector, when opened, allows for manual pressure injection using a small syringe with a plunger and piston to deliver liquid foods like water. The lower connector allows for the injection of thicker foods like minced meat or vegetables, or mechanically pulverized into a paste or porridge-like consistency, such as noodles, using a pusher and a 100ml syringe. This increases dietary fiber, aids bowel movements, and promotes digestion and nutrient delivery. However, it's crucial not to feed too much or too quickly at once, as this can lead to incomplete gastric emptying and esophageal reflux.

[0003] Children with esophageal stricture have a high chance of restenosis after balloon dilation treatment. Esophageal stricture can affect a child's normal eating. In order to ensure that the child receives adequate nutrition, a nasogastric tube is needed to deliver liquid food. However, the existing nasogastric tube has a fixed diameter and does not provide support for the esophagus. Therefore, it is necessary to improve the structure of the existing nasogastric tube by adding a dilation balloon. The balloon is periodically inflated to prevent the esophageal stricture from contracting and restenosis. Summary of the Invention

[0029] Working principle: When in use, insert the main body 1 of the gastric tube into the stomach. When the inflatable bladder 9 needs to be inflated, squeeze the rubber inflator 16. The gas generated by the rubber inflator 16 enters the air inlet 11 through the air inlet tube 12. After entering the air inlet 11, the gas enters the inflatable bladder 9 through the air inlet groove 10, and the inflatable bladder 9 inflates. Remove the air inlet tube 12 from the air inlet 11 and plug the air inlet 11 with a plug to prevent the esophageal stricture from constricting and restenosis.
