Background technique

Nasointestinal tubes are widely used in clinical work. In clinical work, when medical personnel place a tube on a patient, they usually insert the tube into the stomach through blind insertion, and the nasointestinal tube passes through the pylorus by itself through gastric peristalsis. There are also some products with a helical front end and a memory function. Under the action of gastric peristalsis, the head end of the nasointestinal tube can enter the intestinal cavity through the pylorus more easily. It should be pointed out that many critically ill patients often have weakened or disappeared gastrointestinal motility. At this time, it is necessary to operate through the pylorus with the help of a gastroscope, which not only takes a long time, but also further increases the patient's pain and medical expenses.
