Abstract
【選択図】 図3
Description
I.初期位置:可撓性ディスク7は近位方向において上方に付勢され、そしてデバイスハウジングの縮小直径セクション9の下方にある。
II.最小使用者用量より少ない用量がダイヤルされている。可撓性ディスク7はそれが小さくなった直径セクション9に入ると形状を変化させている。使用者が用量送達を試みた場合(即ち、ドライバを遠位方向に動かすことにより)、可撓性ディスクは小さくなった直径セクション上にロックされ、それによってドライバの動き及びその結果薬剤の設定用量の送達を防止する。
IIIa.最小使用者用量がダイヤルされている。可撓性ディスクは取り除かれ又は小さくなった直径セクションから軸方向に離れて、それ故にその元の自由な凹状に戻り又は逆戻り転換する。
IIIb.使用者は正しい用量のダイヤルをし続ける。ドライバ5及び可撓性ディスク7はダイヤル用量が増加すると近位方向に移動する。
IV.用量が送達されると、可撓性ディスクは変形するが、しかし転換せず、そして最小引き摺り又は摩擦により小さくなった直径セクションに移動する。一度用量が完全に送達されると、可撓性ディスクは次の用量動作に備えてその自由な又は弛緩位置に戻る。
