    • An infusion pump device (10) comprises a primary reservoir (11) for liquid medicament, a pump (14, 16) with a secondary reservoir (14) that is able to retrieve liquid medicament from the primary reservoir and to subsequently dosing said liquid medicament from the secondary reservoir in incremental steps, a first upstream conduit ( 24) fluidly connecting the primary reservoir with the pump, a second downstream conduit ( 25, 28) fluidly connected to the pump for transporting the liquid medicament to an infusion site interface (30), a valve (35) for alternatingly connecting the pump to one of the two conduits, and a control unit configured to control the operation of the infusion pump device. For filling the fluidic system (24, 13, 25, 28) of the infusion pump device with liquid medicament prior to infusion operation, the control unit causes the infusion pump device to carry out the following steps: (a) bringing the pump to an initial state where an inner volume (13) of the secondary reservoir is minimal; (b) switching the valve to a first state, in which the secondary reservoir is connected to the first conduit and the primary reservoir; (c) retrieving liquid medicament from the primary reservoir, wherein the retrieved liquid volume (V C ) is at least equal to the inner volume (V B ) of the first upstream conduit; (d) switching the valve to a second state, in which the secondary reservoir is connected to the second downstream conduit; (e) expelling the contents in the secondary reservoir into the second downstream conduit; (f) switching the valve to the first state; (g ) retrieving liquid medicament from the primary reservoir, wherein the retrieved liquid volume (V C ) is at least equal to the inner volume (V D + V E + V F ) of the second downstream conduit; (h) switching the valve to the second state; and (i) expelling the contents in the secondary reservoir into the second downstream conduit by shifting the piston to the initial position.
    • 输液泵装置(10)包括用于液体药物的主储存器(11),具有辅助储存器(14)的泵(14,16),其能够从主储器回收液体药物,并随后对所述液体药物 从次级容器以增量步骤,将流体连接初级容器与泵的第一上游管道(24),流体连接到泵的第二下游管道(25,28),用于将液体药物输送到注射部位接口(30 ),用于将泵交替地连接到两个管道中的一个的阀(35),以及被配置为控制输注泵装置的操作的控制单元。 为了在输注操作之前用液体药物填充输液泵装置的流体系统(24,13,25,28),控制单元使输液泵装置执行以下步骤:(a)使泵进入 初级状态,其中二级容器的内容积(13)最小; (b)将所述阀切换到第一状态,其中所述次级储存器连接到所述第一管道和所述主储存器; (c)从主贮存器回收液体药物,其中回收的液体体积(VC)至少等于第一上游导管的内部体积(VB); (d)将所述阀切换到第二状态,其中所述辅助储存器连接到所述第二下游导管; (e)将第二储存器中的内容物排出到第二下游导管中; (f)将阀切换到第一状态; (g)从主储存器回收液体药物,其中回收的液体体积(VC)至少等于第二下游导管的内部体积(VD + VE + VF); (h)将阀切换到第二状态; 和(i)通过将活塞移动到初始位置将第二储存器中的内容物排出到第二下游导管中。
