AI Technical Summary

Technical Problem

Existing disposable nasogastric tubes can only be used for single treatment procedures, which cannot meet the treatment needs of patients with multiple complications during nasogastric tube treatment.

Method used

A multifunctional nasogastric tube comprising a guide cannula and a combined feeding tube was designed. The combined feeding tube has two independent tube bodies, used for delivering nutrients and for negative pressure aspiration, respectively, and is fixed by the guide cannula to achieve simultaneous treatment of multiple complications.

Benefits of technology

This technology reduces the pain caused by repeated intubation during nasogastric tube treatment, and enables simultaneous nutrient delivery, negative pressure aspiration, oxygen supply, and sputum suction, thereby improving treatment efficiency and patient comfort.

Abstract

The application discloses a disposable multifunctional nasogastric tube, which comprises a guide sleeve and a combined feeding tube with a length greater than the guide sleeve, and the end surface of the combined feeding tube is provided with a side hole; the end of the guide sleeve is provided with an outer tube connecting seat, the end of the combined feeding tube penetrating through the end of the outer tube connecting seat is connected with a luer lock connector; and a flip cover assembly is connected to the outer wall of the outer tube connecting seat, wherein the combined feeding tube comprises at least two independent pipe bodies for conveying nutrient substances or performing negative pressure extraction work. The application is characterized in that the guide sleeve is used for fixing the guiding cavity from the nasal cavity to the throat part, the combined feeding tube penetrates into the esophagus from the guide sleeve and enters the stomach or the intestinal tract position, and the pain of the patient caused by repeated intubation is reduced. The combined feeding tube has two pipe bodies with conveying functions, so that the treatment measures for the stomach or the intestinal tract part can be realized according to the length of the deep pipe body, and the implementation of the synchronous treatment measures for the complications is realized.
