AI Technical Summary

Technical Problem

Traditional nasogastric feeding devices are difficult to maintain food temperature effectively, lack convenient temperature control methods, and the feeding tube is prone to bending and traction, affecting patient comfort and nutrient absorption.

Method used

A nasogastric feeding device was designed, comprising a flexible sleeve and a heating bag. The sleeve is made of insulating material and has an adjustable fixing structure. The heating bag is distributed along the length of the sleeve and has an embedded temperature control component. Temperature adjustment and display are achieved through a constant temperature controller. The nasogastric feeding tube is fixed together with an anti-slip silicone strip.

Benefits of technology

It enables rapid and stable temperature increase of food in the nasogastric tube, allowing patients to adjust the temperature independently, improving ease of use and safety, preventing the nasogastric tube from slipping or being pulled, and ensuring smooth nasogastric feeding.

Abstract

This nasogastric feeding device offers convenient temperature adjustment, addressing the shortcomings of traditional devices that lack convenient temperature control, prevent patients from actively adjusting the temperature, and are prone to traction issues with the feeding tube. It includes a flexible sleeve that wraps around and secures to the patient's upper arm. The sleeve is made of insulating material and features an adjustable fastening structure. Multiple strip-shaped heating bags are evenly distributed along the length of the sleeve, each filled with a liquid heat-conducting medium. Adjacent heating bags form a covering groove for inserting the feeding tube. Each heating bag contains a temperature control component, including a heating element, a temperature sensor, and a thermostat integrated into the sleeve surface with terminals electrically connected to a control module. The thermostat forms a closed-loop control circuit with all heating bags via wires, enabling real-time adjustment and display of temperature parameters. This design heats the feeding tube, preventing cooling, and offers convenient temperature adjustment and high comfort.
