The present invention discloses a nasogastric tube including a tube body and an inflatable portion. The tube body includes a proximal end and a distal end. The inflatable portion is disposed on the tube body and close to the distal end. The inflatable portion is disposed along the longitudinal direction of the tube body. The inflatable portion includes a chamber. When a fluid fills into the chamber of the inflatable portion, the inflatable portion will inflate toward one side of the tube body and press down the tube body, which is resulted in elevation of the distal end to shorten the distance between the distal end and a posterior pharyngeal wall.本發明揭露一種鼻胃管，鼻胃管包括一管狀本體以及一可膨脹單元。管狀本體包括一近端以及一遠端。可膨脹單元沿管狀本體之長軸方向固定於管狀本體上並鄰近遠端，可膨脹單元具有一空腔，其中充入空腔之一流體使可膨脹單元向管狀本體之一側膨脹並下壓管狀本體，使遠端向上抬升並使遠端與後咽壁之距離縮短。
