PROBLEM TO BE SOLVED: To provide a medicament preparation appliance of novel structure capable of preventing an erroneous operation of separating a first tubular body from a second tubular body before mixing of a content of a first vial and a content of a second vial has been finished.SOLUTION: An inner member 25 provided with a first hollow needle 94 and a second hollow needle 128 is movably stored inside a first tubular body 12 and a second tubular body 14 that are coupled by coupling means 46 and 68 so as to prevent a releasing operation of the coupling means 46 and 68 when the inner member 25 is not moved to the side of the first vial 146. The medicament preparation appliance includes separation regulation means 36, 62, 92a and 92b that allow the releasing operation of the coupling means 46 and 68 when the inner member 25 is moved to the side of the first vial 146.COPYRIGHT: (C)2014,JPO&INPIT【課題】第1バイアルの内容物と第2バイアルの内容物の混合が完了する前に第1筒体と第2筒体が分離されてしまう誤操作を防止することの出来る、新規な構造の薬剤調製器具を提供すること。【解決手段】第1中空針94と第2中空針128が設けられたインナ部材25を、連結手段46,68で連結された第1筒体12と第2筒体14の内部に移動可能に収容して、該インナ部材25が第1バイアル146側に移動されていない状態では該連結手段46,68の解除操作を阻止すると共に、該インナ部材25が該第1バイアル146側に移動された場合には該連結手段46,68の解除操作を許容する分離規制手段36,62,92a,92bを設けた。【選択図】図2
