AI Technical Summary

Technical Problem

The nasogastric tubes are prone to blockage during use, and the existing dredging methods are cumbersome, which may lead to discomfort and hygiene and safety hazards.

Method used

A nasal intestinal tube is designed with a closed door assembly and a drive assembly that enables clearance online without removing the tube. The inner cavity of the tube is closed or opened by the driving assembly, and the low pressure of sodium bicarbonate flushing liquid is injected into the first water pipe for repeated flushing, and finally take warm water and extract it.

Benefits of technology

Abstract

The nasointestinal tube comprises a tube body, a sealing door set, a driving assembly and a first water tube, one end of the tube body is an imbedding end, the other end of the tube body is an exposed end, and the exposed end can be communicated with an external nutrition injection tube; the number of the sealing door assemblies is two, the two sealing door assemblies are arranged at the two ends of the pipe body respectively, each sealing door assembly comprises a plurality of movable doors which are arranged in a circumferential array mode, and when the movable doors draw close to each other, an inner cavity of the pipe body can be blocked; the driving assembly is connected with the movable doors of the two sealing door assemblies and can drive the movable doors of the sealing door assemblies to be close to each other at the same time to block an inner cavity of the pipe body or to be separated at the same time so that the pipe body can be unblocked. And the first water pipe is communicated with the inner cavity of the pipe body. By the adoption of the nasointestinal tube, the whole operation process is simple, meanwhile, the comfort and sanitary safety of a patient can be greatly improved, the nasointestinal tube does not need to be taken down for special dredging, and then the pain of the patient and the convenience of a doctor can be greatly relieved.
