Abstract
Description
前記注入速度調節ユニットは、前記加圧プランジャーが貫通し、前記注入速度調節ユニットの内部への液体の侵入を防止する防水部をさらに含みうる。
このような気密部材143は、アスピレーション施術のために使われるものであって、アスピレーション施術を行わない場合には、気密部材143をプランジャーキャップ142から除去されても良い。
このような加圧プランジャーアップ/ダウン駆動モジュール150は、加圧プランジャー 140に歯合されるリードスクリュー151と、リードスクリュー151を回転させる駆動モータ152と、加圧プランジャー140の移動をガイドするガイド部153と、を含む。
注入ユニット結合用胴部131に設けられる挿入溝132は、ハウジング121の通過孔123と連通される。
このように、本実施形態による薬液注入装置は、充電式バッテリを無接点方式で充電することによって、充電が簡便であり、接点不良が発生せず、漏電による破損などを防止することができる。
このように、本実施形態による薬液注入装置は、注入速度調節ユニット120の加圧プランジャー140が注射液Jを加圧することによって、注射液Jの注入のために、被施術者が直接注射液Jを加圧する必要がなく、加圧プランジャー140をアップ/ダウンさせる加圧プランジャーアップ/ダウン駆動モジュール150が、加圧プランジャー140と同一軸線上に配されることによって、注入速度調節ユニット120を小型化またはスリム化することができる。
