The present invention discloses a nasogastric tube including a tube body and a pressure portion. The tube body includes a proximal end and a distal end. The pressure portion is disposed on the tube body and close to the distal end. The pressure portion is disposed along the longitudinal direction of the tube body. The pressure portion includes a chamber. When a fluid fills into the chamber of the pressure portion, a pressure of the pressure portion will increase to increase a portion of the tube body where the pressure portion is located, which is resulted in elevation of the distal end to shorten a distance between the distal end and a posterior pharyngeal wall.本發明揭露一種鼻胃管,用於設置於一鼻胃部。該鼻胃部具有一後咽壁、一下鼻甲、一鼻咽部後上壁與一軟顎。該鼻胃管包括一管狀本體以及一壓力單元。該管狀本體具有一長軸方向,包括一近端以及一遠端,且該遠端與該鼻胃部之後咽壁相距一距離。該壓力單元係沿該長軸方向設置於該管狀本體上並鄰近該遠端。該壓力單元具有一空腔,其中充入該空腔之一流體使該壓力單元之壓力上升,並使該壓力單元所在之管狀本體之壓力高於其他部位,使該遠端向上抬升並使該遠端與該後咽壁之距離縮短。2‧‧‧鼻胃管1‧‧‧管狀本體122‧‧‧壓力單元3‧‧‧Y型接頭31‧‧‧第一接口32‧‧‧第二接口E1‧‧‧近端E2‧‧‧遠端DL‧‧‧長軸方向O3‧‧‧第三開口
