  • Publication number: 20110208127
    Abstract: A dosing device for an infusion system comprises a dosing unit having a variable volume and at least one opening in fluid connection with the variable volume, through which opening the variable volume can be filled with a substance or the substance can be dispensed from the variable volume. The dosing device is operable in a first state for filling the substance from a supply conduit, in a second state for preventing filling and dispensing, or in a third state for dispensing through a dispensing conduit. No direct fluid connection exists between the supply conduit and the dispensing conduit at any time. Methods for dosing a substance with the dosing device.

  • Publication number: 20110108158
    Abstract: A device, kit, and method for transferring a liquid medicament from a supply container to a flexible reservoir container are disclosed. The device may comprise a compartment unit and an adapter unit. The compartment unit may have a sealingly closable chamber, arranged for housing the flexible reservoir container and for being fluidly connected with a pump mechanism. The adapter unit may have at least one transfer passage for transferring liquid from a supply container connected to the adapter unit to the flexible reservoir container, and a separator arranged in the transfer passage for separating gas bubbles from a liquid streaming through the transfer passage. The separator may be fluidly connected to the chamber.

  • Publication number: 20110066108
    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 of the chamber 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

  • Publication number: 20100245104
    Abstract: An automatically operating injection device with an occlusion alarm unit and a method for determining an injection occlusion are disclosed. The method includes generating a plurality of evaluation forces based on a series of force measurements and based on an evaluation time period; determining whether an occlusion exists based on either an evaluation of the plurality of evaluation forces or whether one or more of the series of force measurements exceeds a force threshold; and providing an injection occlusion alarm if an occlusion is determined to exist.
