Abstract
【解決手段】注射器12の流体チャンバ内に含まれる流体の量及び/または流体の濃度を示すために、本体の外壁に印刷されたハッチマークを有する。実質的に円錐台状の内部空洞を画定する注射器先端部は、注射器の端壁から延びる。針ハブは針を保持し、針ハブが、注射器に選択的に固定して取り付けられ得るように構成される。針ハブの円錐台状部材は、針ハブが注射器に固定されると、注射器先端部の円錐台状空洞に嵌合係合して、流体密封密閉を形成する。流体チャンバ内に位置付けられるプランジャを押し下げることができ、プランジャに取り付けられたピストンキャップは、チャンバ内の流体をチャンバから追い出し、注射器先端部を通して針に入れる。
