PROBLEM TO BE SOLVED: To provide a tube feeding nutrient injection device extremely simple in operation.SOLUTION: This tube feeding nutrient injection device 10 includes a colorless transparent nutrient housing container 11 made of glass housing a tube feeding nutrient F, a lid part 12 threaded with the opening 11b of the nutrient housing container 11 and the pump dispenser part 13 inserted in the lid part 12 in a detachable manner. The inner diameter φ2 of the opening 11b of the nutrient housing container 11 to the inner diameter φ1 of the bottom part 11a of the nutrient housing container 11 is 70% or more. The pump dispenser part 13 is equipped with a pressure receiving operation part 13a protruding outwardly from the lid part 12 to reciprocally move in the direction of the axis L of the nutrient housing container 11 and a pump part 13b cooperated with the reciprocating movement of the pressure receiving operation part 13a to discharge the tube feeding nutrient F in the nutrient housing container 11 to the outside of the nutrient housing container 11.COPYRIGHT: (C)2013,JPO&INPIT【課題】操作が極めて簡便な経管栄養剤の注入装置を提供する。【解決手段】経管栄養剤の注入装置10は、経管栄養剤Fを収容する無色透明なガラス製の栄養剤収納容器11と、栄養剤収納容器11の開口部11bへ螺合される蓋部12と、蓋部12に対して着脱可能に挿着されるポンプディスペンサ部13とを備える。栄養剤収納容器11の底部11aの内径φ1に対する栄養剤収納容器11の開口部11bの内径φ2は70%以上である。ポンプディスペンサ部13は、蓋部12から外方へ突出して栄養剤収納容器11の軸L方向に往復動する受圧操作部13aと、受圧操作部13aの往復動に連動して栄養剤収納容器11内の経管栄養剤Fを栄養剤収納容器11外へ吐出するポンプ部13bとを備える。【選択図】 図1
