Design and application of a new nasointestinal canal with outer sleeve
一种带套管新型鼻肠管的设计与应用

摘要

专家推荐对于误吸风险高、不耐受胃内营养的患者推荐幽门后喂养，而留置鼻肠管操作核心点就在于肠管快速到达幽门并通过幽门。临床上方法众多，但这些方法存在问题就在于操作难度大，耗费人力，患者舒适度差。另外目前市面上的肠管在更换时如同重新置管。为了解决以上问题，作者设计了一款带套管鼻肠管，并获得国家实用新型专利（专利号：ZL 2022 2 3386672.X）。该肠管主要由带水囊外套管，尖端开口肠管，带刻度及可接光源尖端发光的导丝组成，外套管辅助快速到达幽门，导丝辅助判断肠管尖端走向并在换管时起到引导作用。大大减少操作难度，节省时间及人力成本，换管变得很容易，值得临床推广。

Abstract

Experts recommend pyloric feeding for patients with high risk of aspiration and intolerance gastric nutrition, and the core point of indwelling nasenteral tube operation is that the intestinal tubes quickly reach and pass through the pylorus. There are many clinical methods, but the problems of these methods lie in the difficulty of operation, manpower consumption and poor patient comfort. In addition, the intestinal tubes on the market are rereplaced when replaced. In order to solve the above problems, the author designed a Nasointestinal canal with outer sleeve, and obtained the national utility model patent (patent no.: ZL 2022 2 3386672.X). The Nasointestinal canal is mainly composed of a mantle tube with a water sac, an open intestinal tube at the tip, a guide wire with scale and the tip of the light source. The mantle tube helps reach the pylorus quickly, and the guide wire helps judging the direction of the intestinal tip and plays a guiding role when changing the tube. Greatly reducing the difficulty of operation, saving time and labor costs, tube change becomes very easy, worthy of clinical promotion.
