PROBLEM TO BE SOLVED: To provide a medical solution spraying administration apparatus administering a proper amount of a medical solution to an affected part in a living body in a short time.SOLUTION: The medical solution spraying administration apparatus includes a medical solution filling part 2 filled with the medical solution X inside a catheter 3 with a proximal end connected to the medical solution filling part 2 and with a distal end formed with an ejection hole 30 for ejecting the medical solution X an ejection mechanism 4 ejecting the medical solution X in the medical solution filling part 2 from the ejection hole 30 through the inside of the catheter 3 and a voltage applying part 5 applying voltage to the medical solution X fed to the ejection hole 30 by the ejection mechanism 4. A plurality of ejection holes 30 are formed at the distal end of the catheter 3, and the plurality of ejection holes 30 are disposed at spaces of 20 &mum or more.COPYRIGHT: (C)2010,JPO&INPIT【課題】生体の体内の患部に薬液を短時間に適正量投与することができる薬液噴霧投与装置を提供することを目的としている。【解決手段】内部に薬液Xが充填される薬液充填部2と、基端が薬液充填部2に接続されるとともに先端に薬液Xを吐出する吐出孔30が形成されたカテーテル3と、薬液充填部2内の薬液Xを、カテーテル3内を通して吐出孔30から吐出させる吐出機構4と、吐出機構4によって吐出孔30に送られる薬液Xに電圧を印加する電圧印加部5と、を備え、吐出孔30がカテーテル3の先端に複数形成されているとともに、これら複数の吐出孔30が20μm以上の間隔をあけて配設されている。【選択図】図1
