Anti-bending self-guiding nasointestinal tube and using method thereof

Abstract

The invention discloses an anti-bending self-guiding nasointestinal tube and a using method thereof.The anti-bending self-guiding nasointestinal tube comprises a nasointestinal tube body, the nasointestinal tube body comprises a shell and a hollow tube arranged in the axial direction of the shell, one end of the hollow tube is open to the end face of the free end of the nasointestinal tube, and the shell of the nasointestinal tube comprises an esophagus section, an anti-bending section and a functional section which are integrally arranged; a plurality of supporting air bags are arranged in the anti-bending section side by side, each supporting air bag is communicated with a fixed air bag through a pipeline, and the adjacent supporting air bags are tightly attached to each other in the inflated state. According to the anti-bending self-guiding nasointestinal tube and the using method thereof, the device is simple in structure and convenient to operate, whether the end of the nasointestinal tube is inserted in place or not can be visually determined through various parameters, and the phenomenon that the nasointestinal tube is bent in the stomach can be effectively avoided through the arrangement of the air bag.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and particularly relates to an anti-bending self-guiding nasoenteric tube and a method for using the same. Background technique [0002] The use of nasoenteric tubes is becoming more and more widespread in critical care medicine. On the one hand, the implantation of nasoenteric tubes has become the only channel for enteral nutrition for patients with gastric emptying disorders. There is a great risk of reflux aspiration. Many nutrition guidelines clearly recommend that by placing a nasoenteric tube and giving patients post-pyloric feeding (using the anti-reflux effect of the pyloric sphincter), the probability of aspiration can be greatly reduced. However, the routine clinical placement of nasoenteric tubes requires gastroscopic guidance. This invasive operation increases the risk of treatment for patients and also becomes a technical obstacle to the implementation of treatment. [0003]...

AI Technical Summary

Problems solved by technology

However, the routine clinical placement of naso-intestinal tubes requires gastroscopy guidance. This invasive operation increases the risk of treatment for patients and also becomes a technical obstacle to the implementation of treatment.

[0003] At the same time, in the existing nasointestinal tube insertion operation, due to the weak rigidity of the nasointestinal tube, the end of the gastrointestinal tube is easily bent or turned back after being blocked during the process from the end of the gastrointestinal tube along the gastric cardia to the pylorus, and there is no ultrasound status The operator cannot quickly and accurately judge whether the end of the nasointestinal tube is in the pylorus, so that the patient cannot be treated quickly and timely; Whether the end is still in the pylorus, these all depend on the position information of the end of the nasointestinal tube
