摘　　要：目前鼻空肠营养管大多需在胃镜辅助下置入,这给患者带来一定痛苦,且操作也较为繁琐。磁性空肠营养管基于磁导航技术原理,通过在现有空肠营养管的头端嵌入小磁体,借助体外导航磁体吸引牵拉,可将空肠营养管置入到空肠起始部,该方法操作简单,刺激小,可减轻患者痛苦。At present, the nose-jejunum nutrition tube is put mostly via gastroscope, which makes patients suffer pain at some extent while makes the whole procedure complicated. Based on magnetic navigation techniques, the magnetic jejunum nutrition tube, consisting of an existing jejunum nutrition tube and a small magnetic body embedded at the head, can be placed at the starting part of jejunum, through attraction and traction of external navigation magnet. The novel device is easy operated with little simulates, which can relieve the pain patients suffering.
