Description

Intestinal canal with visual function

Technical Field

The utility model belongs to the technical field of medical catheters, and particularly relates to an intestinal canal with a visual function.

Background

An intestinal tube is a tube that in special cases aids a patient who cannot swallow in infusing a nutrient solution into the intestine. Generally consists of a catheter, a connector, a guide wire and the like. Currently, nasal and intestinal tubes are commonly used in the market, and are required to be inserted through nostrils, through the pharynx, and through the esophagus into the intestines. When the intubation is performed, the patient is required to put on the body, clean and lubricate the nasal cavity, the head of the patient is leaned back, the intestinal canal and the nostril are inserted at an angle of 60 degrees, and the intubation is continuously inserted into the nasopharynx; when the intestinal canal is inserted into 15CM (can pharynx), 1-2mL of sterilized paraffin oil is instilled along the outer wall of the intestinal canal, and then the head of a patient is lifted up to enable the lower jaw of the patient to be clung to the chest wall, so that the radian of the throat part is increased, the intestinal canal can slide along the rear wall conveniently, and the intestinal canal can smoothly enter the esophagus through the throat part. At this time, the patient is instructed to swallow while slowly inserting the intestinal tube. Furthermore, the approach to the intestine via the stomach also requires a very difficult gateway-the pylorus. It can be said that the intestinal canal needs to be subjected to a long and complicated process when being placed in the human body. The blind insertion method adopted in the current market needs to rely on medical staff to have abundant insertion experience, and the situation that the intestinal canal enters the human body to be inserted in the insertion process cannot be seen, so that the success rate of the tube placement is difficult to achieve by 100%. To ensure successful placement, the gastrointestinal portion must be irradiated with an X-ray machine for confirmation. For a special patient who has undergone stomach operation, the patient with asymmetrical stomach shape can only make visual tube placement by means of a gastroscope, but the head end of an intestinal canal cannot be adjusted, the tube placement has certain difficulty, the lower gastroscope is an extra work for medical staff, the comfort level of the gastroscope is poor, and the patient is painful. It is therefore necessary to develop an intestinal canal that can be visualized throughout the entire procedure when a tube is placed.
