  • Publication number: 20110132490
    Abstract: A device for filling a flexible container and a method thereof are disclosed. The device may include a pressurizing chamber and an evacuation chamber. A first displacement piston is sealingly and slideably arranged within the pressurizing chamber to define an inner volume within the pressurizing chamber that is fluidly connected to a pressurizing conduit. A second displacement piston is sealingly and slideably arranged within the evacuation chamber to define an inner volume within the evacuation chamber that is fluidly connected to an evacuation conduit. A reservoir adapter is fluidly connected to the pressurizing conduit and connects to a liquid reservoir. A container adapter is fluidly connected to the evacuation conduit and connects with a flexible container. A transfer conduit is fluidly connected to the reservoir adapter and the container adapter. A valve fluidly connects the container adapter to the evacuation conduit or the transfer conduit.

  • 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: 20100241077
    Abstract: Cannula assemblies with pressure sensors made of stacked coplanar layers and ambulatory infusion systems comprising the same are disclosed. The cannula assemblies include a hub and an infusion cannula. The hub includes a pressure sensor and a fluid channel fluidly coupled to the infusion cannula. The pressure sensor is formed from a stack of coplanar layers including a top layer, a base layer an electrode layer and a counter electrode layer. The fluid channel is positioned between the top layer and the base layer. The electrode layer is positioned between the top layer and the base layer and coupled to the fluid channel. The counter-electrode layer is positioned between the top layer and the electrode layer. A spacer layer having a through cut-out defining an electrode cavity is disposed between the top layer and the base layer such that the electrode layer extends across the electrode cavity.
