Radiopaque nasoenteric tube

By designing a conical and rounded head at the front end of the nasoenteric tube for easy insertion, and using an air bladder to fix the internal liquid feeding chamber and air chamber, the connector and auxiliary connecting tube ensure stability. This solves the problems of the nasoenteric tube falling off under gastrointestinal peristalsis and the inconvenience of connecting the nutrient solution, thus achieving stable nutrient input.

AI Technical Summary

Technical Problem

Existing nasoenteric tubes are prone to detachment or movement due to gastrointestinal peristalsis, and there are also inconvenient connections to nutrient solution tubing.

Method used

A nasoenteric tube visible under X-ray was designed. The front end of the nasoenteric tube is equipped with a conical head and a round head for easy insertion. The inside is equipped with a liquid feeding chamber and an air chamber. The air bladder is used to fix it to the upper part of the jejunum. The connector and auxiliary connecting tube are used for stable connection. The stability of insertion is ensured by a guide wire and an anti-dislodgement ring.

Benefits of technology

It effectively prevents the nasoenteric tube from dislodging, ensures the stability and sealing of nutrient input, and improves the stability and connection reliability of the nasoenteric tube in the gastrointestinal tract.
