Description
特許文献1には、回転可能なプランジャーが、その内部表面上に多くの平行なラックを有し、その各々が投与量が設定されるときにプランジャーが回転するにつれて第一歯車と係合するようになる注射器からプリセット量の薬剤を正確に投与する機構が教示されている。装置は、第一歯車と共に回転して、選択された投与量がデリバリーされると、スラストロッドを注射器内に駆動させる第二歯車を有する。この装置は、プリセット投与量の投与に関して有用な実施態様を提供するものの、投与量設定の直観性については、投与量設定中に部品を回転させる必要があるので未解決のままである。
基端部及び先端部を有するハウジング;
駆動部材が長手方向に可動であるように、上記ハウジング内に位置する該駆動部材;
ハウジングを通して操作し、かつドラッグデリバリーデバイスの先端部に向けて長手方向に力を移動させるように適合されるピストン棒;
該ピストン棒と開放可能なように係合し、そして上記駆動部材と係合し、かつ上記ハウジングと係合する回転手段;
を含み、
a)上記駆動部材が上記ハウジングに対して基端部側に動くとき、上記回転手段が上記ピストン棒に対して基端部側に動く;
b)上記駆動部材が先端部側に動くとき、上記回転手段が先端側に動いて上記ピストン棒をデバイスの先端部側に向けて移動させる;
ことを特徴とする駆動機構が提供される。
先ず、図1から3を参照すると、本発明のドラッグデリバリーデバイスが示されてある。
図4から5を参照すると、本発明のドラッグデリバリーデバイスの代替実施態様を示されてある。
ラック(115)の歯はギア(113)の歯と恒久的に係合する。
