For those that do, the tube is easily blocked in the intestine. The front end of an ordinary intestinal tube is easily attached to the wall, blocked or broken. Secondly, due to the narrow structure of the human pylorus, intestinal tube placement is difficult. Some visual devices can even assist in tube placement. However, because the front end of traditional tubes is too hard and cannot be bent, it is difficult for the visual device to pull the tube, and the problem of difficulty in tube placement is not solved. During the tube placement process, the tube opening will cause secondary damage to the patient's gastrointestinal mucosa, increasing the risks and hazards to patients and medical staff.
