Claims (4)
- 駆動ユニットによって回転されるピニオンと丸い押し棒のラックとの噛み合いにより、押し棒をゆっくり移動させ、麻酔液充填カートリッジのプランジャゴム栓を押して麻酔液をカートリッジから注射針を通して排出させるようにした歯科用麻酔液充填カートリッジ式電動注射器において、支持ブロックの貫通孔に移動自在に設けられ、押し棒が移動可能に挿入され、側面に押し棒のラックと整合して形成されたラックを有する継ぎ足し管と、押し棒がカートリッジの麻酔液収容長さに相当する距離の中間に達したとき、押し棒が継ぎ足し管のラックをピニオンに噛み合わせるべく継ぎ足し管を引く手段とを、含み、前記押し棒は、継ぎ足し管のラックとピニオンの噛み合いにより、前記カートリッジの麻酔液収容長さに相当する距離のうちの残りの距離、継ぎ足し管と一緒に移動する、ことを特徴とする歯科用麻酔液充填カートリッジ式電動注射器。
- 押し棒の移動中、継ぎ足し管を支持ブロックに対して移動しないように支持ブロックに解放可能に結合するための手段を含み、該結合手段は、継ぎ足し管の前端部分に形成された保持穴に受け入れられた係止ボールと、継ぎ足し管を支持ブロックに固定するために、保持穴内にあって押し棒の円形外面によって継ぎ足し管11の外面から押し出される係止ボールの一部が係合するようになった、支持ブロックの貫通孔に形成された凹部と、を含む、請求項1に記載の歯科用麻酔液充填カートリッジ式電動注射器。
- 押し棒がカートリッジの麻酔液収容長さに相当する距離の中間に達したとき、前記継ぎ足し管の支持ブロックに対する結合を解くために、前記係止ボールに対峙して前記押し棒の外面に形成された凹部を含む、請求項2に記載の歯科用麻酔液充填カートリッジ式電動注射器。
- 前記継ぎ足し管は、押し棒の外径とほぼ等しい内径を有する前方部分と、その内径よりも大きい内径を有する後方部分と、を含み、前記前方部分と後方部分の接合部が肩部を画成し、前記継ぎ足し管を引く手段は、前記押し棒の後端部に設けられ、前記継ぎ足し管の後方部分内を移動して前記肩部に当接する突起からなる、請求項1に記載の歯科用麻酔液充填カートリッジ式電動注射器。
