Description

Intestinal canal with visual function

Technical Field

The invention 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 helps patients who cannot swallow infuse nutrient solutions into the intestine in special cases. Generally consisting of a catheter, a connector, a guide wire and the like. Currently, the naso-intestinal tube is commonly used in the market, and is inserted through a nostril, passes through a pharynx and enters the intestine through an esophagus. When in intubation, the patient needs to be placed in a proper position, the nasal cavity is cleaned and lubricated, the head of the patient is tilted backwards, the intestinal canal and the nasal cavity are inserted at an angle of 60 degrees, and the patient continues to be inserted into the nasopharynx; when the intestinal canal is inserted to 15CM (meeting pharynx), 1-2mL of sterilized paraffin oil is instilled along the outer wall of the intestinal canal, then the head of a patient is held up, the lower jaw of the patient is tightly attached to the chest wall, the radian of the laryngeal part of the pharynx is increased, the intestinal canal slides along the back wall, and the intestinal canal smoothly passes through the laryngeal part of the pharynx and enters the esophagus. At this point the patient is ordered to swallow the bowel while inserting the tube slowly. Moreover, a very difficult opening, the pylorus, must be experienced in reaching the intestine through the stomach. It can be said that the intestinal tube is required to undergo a long and complicated procedure when it is inserted into the human body. The blind intubation technique adopted in the market at present needs to depend on rich intubation experience of medical staff, and the insertion condition that the intestinal canal enters the inside of a human body cannot be seen in the insertion process, so that the success rate of intubation is difficult to achieve by 100%. In order to ensure successful intubation, the gastrointestinal area must be irradiated by an X-ray machine for confirmation. For a special patient who has performed a stomach operation, the patient with an asymmetric stomach shape can only be visually placed with the aid of a gastroscope, but the head end of an intestinal canal cannot be adjusted in direction, the placement of the intestinal canal is difficult to a certain degree, the gastroscope is not only an extra work for medical staff, the comfort level of the gastroscope is poor, and the patient suffers pain. Therefore, it is necessary to develop a tube for placing intestine that can be seen in the whole course.
