Patent number: 10525211Abstract: An infusion pump device and method for filling a fluidic system of the infusion pump with liquid medicament prior to infusion operation is presented. A control unit causes the infusion pump to: (a) bring a pump to an initial state; (b) switch a valve to a first state connecting a secondary reservoir to a first conduit and a primary reservoir; (c) retrieve medicament from the primary reservoir; (d) switch the valve to a second state connecting the secondary reservoir to a second downstream conduit; (e) expel the secondary reservoir contents into the second downstream conduit; (f) switch the valve to the first state; (g) retrieve the primary reservoir medicament; (h) switch the valve to the second state; and (i) expel the secondary reservoir contents into the second downstream conduit by shifting a piston to the initial position.Type: GrantFiled: October 9, 2013Date of Patent: January 7, 2020Assignee: Roche Diabetes Care, Inc.Inventors: Andreas Geipel, Joerg Dogwiler, Ulrich Haueter, Simon Scheurer, Rudolf Zihlmann, David Teutsch, Florian Kuehni, Reto Schaltegger

Patent number: 9446193Abstract: A dosing unit for an ambulatory infusion pump device is presented. The dosing unit comprises a cylinder pump with a cylinder and a piston arranged in the cylinder. The piston has a shaft with a first threaded segment interacting with a threaded portion of the cylinder and can be displaced along a longitudinal axis of the cylinder by rotating the piston in regard to the cylinder around the axis. Furthermore, the piston allows for the relative or absolute determination of the longitudinal and/or rotational displacement of the piston in regard to the cylinder. In one embodiment, the piston shaft comprises a second segment provided with optically detectable markings that allow the monitoring of the longitudinal and/or rotational displacement of the piston in regard to the cylinder.Type: GrantFiled: October 9, 2013Date of Patent: September 20, 2016Assignee: Roche Diagnostics International AGInventors: Andreas Geipel, Joerg Dogwiler, Ulrich Haueter, Simon Scheurer, Rudolf Zihlmann, David Teutsch, Florian Kuehni, Reto Schaltegger

Patent number: 9402951Abstract: 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).Type: GrantFiled: October 9, 2013Date of Patent: August 2, 2016Assignee: Roche Diagnostics International AGInventors: Andreas Geipel, Joerg Dogwiler, Ulrich Haueter, Simon Scheurer, Rudolf Zihlmann, David Teutsch, Florian Kuehni, Reto Schaltegger
