摘要： An infusion pump assembly includes a locking tab and a pump barrel inside a pump barrel housing, where the pump barrel accommodates a reservoir assembly. The reservoir assembly includes a reservoir and a plunger rod. The infusion pump assembly also includes a locking disc at a terminus of the pump barrel. The locking disc includes a clearance hole for the plunger rod. The locking disc also includes at least one locking tab notch in close proximity with the locking tab. The locking tab is in moveable engagement with the locking tab notch, and the reservoir moves the locking tab from a locked position to an unlocked position when the plunger rod is inserted through clearance hole. The locking disc rotates upon torque being applied to the reservoir assembly, the locking disc rotating from a non-loaded position to a loaded position with respect to the plunger rod and a drive screw.

摘要翻译： 输液泵组件包括在泵筒壳体内的锁定突片和泵筒，其中泵筒容纳储存器组件。 储存器组件包括储存器和柱塞杆。 输液泵组件还包括在泵筒的末端处的锁定盘。 锁定盘包括用于柱塞杆的间隙孔。 锁定盘还包括至少一个与锁定突出部紧密接合的锁定突片凹口。 锁定突出部可与锁定突舌凹口可移动地接合，并且当柱塞杆插入通过间隙孔时，储存器将锁定片从锁定位置移动到解锁位置。 当锁定盘被施加到储存器组件上时，锁定盘旋转，锁定盘相对于柱塞杆和驱动螺杆从非加载位置旋转到加载位置。
