AI Technical Summary

Technical Problem

Patients with dysphagia have difficulty safely and effectively transferring food boluses to their stomachs when eating, leading to a high risk of aspiration, which may cause serious consequences such as aspiration pneumonia, airway obstruction, and malnutrition.

Method used

A feeding aid device to prevent aspiration was designed, including a food storage box, a measuring cylinder, a piston, and a feeding tube. The measuring cylinder and the piston work together to achieve precise control of the food bolus volume and delivery speed, and the feeding outlet is precisely placed at the base of the tongue to prevent the food bolus from directly entering the airway.

Benefits of technology

It reduces the risk of aspiration and decreases the probability of complications such as aspiration pneumonia, airway obstruction, and secondary malnutrition, ensuring the safety and effectiveness of feeding for patients with dysphagia.

Abstract

The invention discloses a mistaken-suction-preventing feeding auxiliary device for a patient with dysphagia. The mistaken-suction-preventing feeding auxiliary device comprises a food storage box and a feeding device. The food storage box is provided with a containing cavity used for containing dysphagia food. The feeding device comprises a metering cylinder, a piston and a feeding pipe, the metering cylinder is provided with a temporary storage cavity, and the metering cylinder is connected with the food storage box through a feeding pipe; the piston is movably sleeved in the metering cylinder; one end of the feeding pipe is connected with the metering cylinder, and a food outlet is formed in the other end of the feeding pipe. The metering cylinder is matched with the piston, so that the volume of food entering the temporary storage cavity each time can be quantified, and it is ensured that each fed food ball has the stable and consistent volume. When the piston moves forwards, the speed of extruding food can be controlled by adjusting the moving speed of the piston, so that food balls enter the feeding pipe at a slow and uniform flow speed, and the phenomenon that the food balls directly flow into the pharyngeal cavity due to too fast delivery is prevented. The feeding pipe enables the food balls to cross a sensitive area in the front middle of the oral cavity and a complex pushing process and directly reach a starting area of swallowing reflex.
