    • A dosing unit for an ambulatory infusion device and a method of operation are disclosed. The dosing unit includes a stationary member, a movable member, and a plunger. The movable member and the stationary member, together, make a charging valve and a discharging valve. The plunger is located, at least in part, in a metering cavity of the movable member and the movable member is adapted to selectively couple and decouple a driving unit, such that, by operating the driving unit with the movable member being coupled with the driving unit, the movable member moves with the plunger to maintain a position of the plunger relative to the movable member along a displacement axis, and by operating the driving unit with the movable member being decoupled from the driving unit, the plunger is displaced while the position of the movable member is maintained.
    • 公开了一种用于移动式输液装置的计量单元和操作方法。 计量单元包括固定构件,可移动构件和柱塞。 可动构件和固定构件一起制成充气阀和排出阀。 柱塞至少部分地位于可移动构件的计量腔中,并且可移动构件适于选择性地联接和解耦驱动单元,使得通过操作驱动单元,可动构件与驱动联接 单元,可移动构件与柱塞一起移动以沿着位移轴线保持柱塞相对于可动构件的位置,并且通过使可动构件与驱动单元脱离而操作驱动单元,柱塞位移 被保持。
