Development of a new type of nasal feeding device
一种新型鼻饲装置的研制

摘要

随着肠内营养支持技术的广泛应用，鼻饲患者因输注速度不准确、波动大而引发的胃肠道不适问题日益凸显。现有鼻饲装置在控速精确性与稳定性方面存在不足，严重影响患者治疗效果与舒适度。为此，本文研制了一种新型鼻饲装置，通过创新性采用螺杆驱动结构，包括筒体和活塞、螺杆、驱动结构及连接管等，利用螺纹传动实现推杆平稳推进，从而很好控制营养液输注流速。该装置操作简便、便于携带，能够有效降低鼻饲过程中胃肠道不良反应发生率，适用于多种情境的营养支持，具备良好的应用价值与推广前景。

Abstract

With the widespread application of enteral nutrition support technology, gastrointestinal discomfort caused by inaccurate and fluctuating infusion rates in patients receiving nasogastric feeding has become increasingly prominent. The existing nasal feeding devices have deficiencies in speed control accuracy and stability, which seriously affect the treatment effect and comfort of patients. To this end, this article has developed a new type of nasal feeding device that innovatively adopts a screw driven structure, including a cylinder and piston, screw, driving structure, and connecting tube. The push rod is smoothly pushed forward using threaded transmission, thus effectively controlling the flow rate of nutrient solution infusion. This device is easy to operate, portable, and can effectively reduce the incidence of gastrointestinal adverse reactions during nasal feeding. It is suitable for nutritional support in various situations and has good application value and promotion prospects.
