摘要:
An infusion pump device comprising a primary liquid medicament reservoir, a pump with a secondary reservoir to retrieve medicament from the primary reservoir and to subsequently dose the medicament from the secondary reservoir in adjustable volumes (Vdose,i) to a downstream conduit and a control unit to control the operation of the infusion pump device is presented. For metering the volumes (Vdose,i), the control unit causes the infusion pump device to: (a) determine a maximum refill level (VC,max) for the secondary reservoir, based on external parameters, wherein the maximum refill level does not exceed the maximum capacity of the secondary reservoir (b) fill the secondary reservoir with medicament from the primary reservoir to the maximum refill level (VC,max) (c) meter and convey the medicament volumes to the downstream conduit (d) if the secondary reservoir becomes empty, refill the secondary reservoir as in step (b) and continue with step (c).
