PROBLEM TO BE SOLVED: To provide a transfusion device capable of facilitating transfusion action such as an intravenous drip by stably administering medicinal solution sealed in a medicinal solution bag without being restricted by a location.SOLUTION: A transfusion device is applied to a medicinal solution bag 20 in which medicinal solution is sealed, and in which a tube 21 is sealed with its distal end exposed to the outside, the tube including a connection 22 that has portions with different outside diameters continuously formed on the distal end. The transfusion device includes: a device body 10 and a tube pump 30 into which the medicinal solution discharged from the medicinal solution bag 20 is introduced and which supplies the medicinal solution at a preset flow rate. The device body 10 includes a regulation recess that allows a part of a large-diameter portion 221 of the connection 22 to intrude therein and regulates the movement of the large-diameter portion 221 along the central axis direction of the connection 22. A lid body 12 closes an opening 11a of a body section 11, with the part of the large-diameter portion 221 intruding in the regulation recess, thus retaining the medicinal solution bag 20.COPYRIGHT: (C)2013,JPO&INPIT【課題】ロケーションに限られずに薬液バッグに封入された薬液を安定的に投与することで、点滴等の輸液行為を容易なものとすることができる輸液装置を提供すること。【解決手段】内部に薬液が封入され、かつ先端部に異なる外径部位が連続して形成された接続部22が設けられたチューブ21が先端部を外部に露出する態様で封止された薬液バッグ20に適用され、装置本体10と、薬液バッグ20より吐出された薬液を導入し、かつ予め設定された流量にて薬液を供給するチューブポンプ30とを備え、装置本体10は、接続部22の大径部位221の一部が進入することを許容し、かつ大径部位221が接続部22の中心軸方向に沿って移動することを規制する規制凹部を有し、規制凹部に大径部位221の一部が進入した状態で蓋体12が本体部11の開口11aを閉塞することで薬液バッグ20を保持するものである。【選択図】図1
