  • Patent number: 10556057
    Abstract: Micro-fluidic chambers for use in a liquid medicament delivery system, include a bottom substrate and a top cover, the top cover being spaced from the bottom substrate so as to define a height of the chamber, wherein, one or more walls or fillings are positioned in the chamber, the walls or fillings defining a fluid channel there between such that the fluid channel extends from an inlet conduit to an inlet of the chamber to an outlet conduit connected to an outlet of the chamber, wherein, each of the walls or fillings has a height less than the height of the chamber so as to define a fluid gap between a top surface of each wall or filling and the top cover; and wherein, the dimensions of the walls or fillings and the chamber are such that the fluid gap will be filled with liquid by capillary forces via the fluid channel when liquid is introduced into the fluid chamber.

  • Patent number: 9446193
    Abstract: 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.

  • Patent number: 9402951
    Abstract: 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).
