摘要：
A controlled delivery drive mechanism includes a drive housing, a piston, and a biasing member initially retained in an energized state and is configured to bear upon an interface surface of the piston. The piston is configured to translate a plunger seal and a barrel. A tether is connected between the piston and the winch drum to restrain the free expansion of the biasing member and the free axial translation of the piston upon which the biasing member bears upon. The drive mechanism may further include a gear assembly and an escapement regulating mechanism configured to control the rotation of the gear assembly to release the tether from the winch drum. The metering of the tether by the escapement regulating mechanism controls the rate or profile of drug delivery to a user.本發明提供了一種受控遞送驅動機構，包括驅動殼體、活塞、以及偏壓構件，該偏壓構件初始保持在賦能狀態下並且被配置成支承在該活塞的介面表面上。該活塞被配置成用於使柱塞密封件和筒平移。繫繩連接在該活塞與絞盤鼓輪之間以約束該偏壓構件的自由膨脹和該活塞的自由軸向平移，該偏壓構件支承在該活塞上。該驅動機構可以進一步包括齒輪組件和擒縱調節機構，該擒縱調節機構被配置成用於控制該齒輪組件的旋轉以從該絞盤鼓輪上釋放該繫繩。藉由該擒縱調節機構釋放該繫繩的計量來控制向使用者遞送藥物之速率或曲線。
