Abstract
【解決手段】オーバーチューブ50は、チューブ本体51と、液溜まり部53が形成された把持部52とから形成される。チューブ本体51の基端開口部51Aには、把持部52の先端に形成された連結口52Aが水密状態で嵌合され、チューブ本体51に対して把持部52が着脱自在に構成される。液溜まり部53は、チューブ本体51の直径よりも大きい直径の球状に形成され、その内部には円弧状の凹部80が形成される。この凹部80にドーナツ状に形成されたスポンジ82が収納されている。施術時において、チューブ本体51と挿入部12との間の隙間から逆流してきた体液は、凹部80に溜まり、スポンジ82に吸液されて凹部80からの漏水が防止される。
