Description
シリンジに充填されている液剤のうち使用可能とする分量を定めるための使用量設定部と、
前記使用量設定部で定めた前記分量の設定の変更を規制した規制状態と、前記使用量設定部による前記分量の設定の変更を許容した許容状態とに切替可能な設定規制部と、を備える。
前記使用量設定部は、前記シリンジのプランジャを中心とする周方向での回転操作により前記分量の設定を変更する設定操作部を有し、
前記設定規制部は、前記プランジャが進退する進退方向でのスライド操作により前記規制状態と前記許容状態とを切り替える規制操作部を有する、
ようにしてもよい。
前記規制操作部は、
前記プランジャが後退する後退方向と同方向へのスライド操作に伴って前記許容状態を前記規制状態に切り替え、前記プランジャが前進する前進方向と同方向へのスライド操作に伴って前記規制状態を前記許容状態に切り替えるように構成され、
該規制操作部は、前記周方向に対する径方向外方に広がる掛止鍔部を有する、
ようにしてもよい。
筒状であり且つ前記シリンジが挿通された状態で前記プランジャを中心とする前記周方向での回転操作、及び前記プランジャが進退する進退方向でのスライド操作が可能となるように構成される操作筒を備え、
前記使用量設定部と前記設定規制部とは、前記操作筒に含まれる、
ようにしてもよい。
前記使用量設定部は、
前記シリンジのプランジャの鍔部の前面に対向配置され、且つ前記鍔部の前記前面に当接した状態から前記プランジャの進退方向における前方に向かって移動可能である可動受部を有し、
該可動受部が前記鍔部から前進方向に離間する距離に基づいて前記分量の設定をするように構成されていてもよい。
