To more effectively prevent leakage prevention measures and leakage prevention measures from drug-preparing medicines for medicines which risks adverse health effects when leaked, and preventive measures against leakage, and when multiple drugs are administered in combination Provide new means for safe, low cost and convenient way to identify the solution leakage site, prevent leakage and prevent leakage at the site.SOLUTION: A placebo composition containing an edible coloring matter compound as a dye component for solution leak detection and an edible coloring matter compound for use in a placebo composition for detecting solution leakage are sealed and used as a dye component for solution leak detection A vial held in an aqueous solution in a dissolvable state, a wiping tool at the inspection site, purified water for wetting the inspection site, and a sealed storage container for the wiping tool. Also, one or more kinds of solution of placebo composition for detecting solution leakage can be introduced into the infusion solution, and the presence or absence of leakage of each coloring matter compound can be visually checked, or each dye compound wiped off with moistened purified water Detect and identify leak points.Selection drawing None【課題】漏出すると健康上の悪影響を生じる危険性がある医薬の医薬調合用器具並びに医薬投与用器具からのより効果的な漏出防止対策ならびに漏出予防対策、および、複数の医薬を併用投与する場での溶液漏出部位の特定と漏出防止対策ならびに漏出予防対策を、安全、低コストかつ簡便に行う新たな手段の提供。【解決手段】可食性の色素化合物を溶液漏出検出用染料成分として含有させた偽薬組成物と、溶液漏出検出用偽薬組成物に用いる可食性の色素化合物を封入して溶液漏出検出用染料成分として水溶液中に溶解可能に保持したバイアルと、検査箇所の拭き取り具と、検査箇所を湿潤させるための精製水と、拭き取り具の密閉収納容器とを含むキットとする。また、1種以上の、溶液漏出検出用偽薬組成物の溶液を輸液中に投入し、各色素化合物の漏出の有無を視認可能とし、又は、精製水で湿潤させ拭き取られた各色素化合物を検出し、漏出箇所を同定する。【選択図】なし
