TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially, relate to a double -cavity nasogastric tube convenient to put in. BACKGROUND

[0002] Nasogastric tube is a kind of pipeline for nutrition support, gastrointestinal decompression or drug delivery by inserting into stomach or intestinal tract through nasal cavity. It is mainly composed of a soft tube and a syringe or pump connected to the end of the tube. During insertion, the doctor will slowly insert the tube into the nasal cavity, through the throat and esophagus, and finally into the stomach or intestinal tract. After the tube is inserted, the doctor will inject liquid or drug into the tube through the syringe or pump to be delivered into the stomach or intestinal tract. Nasogastric tube has a wide range of applications, including nutrition support after gastrointestinal surgery, decompression during gastrointestinal bleeding, treatment of gastrointestinal diseases, etc. It can provide high-nutrition, easily-digestible diet, and also can be used for drug delivery and cleaning of gastrointestinal tract.
