Abstract: Embodiments described herein relate to a liquid extraction device for extracting liquid from a liquid storage container, the liquid extraction device comprising: a receptacle configured to receive a portion of the liquid storage container; a liquid storage container interface housed within the receptacle, wherein the liquid storage container interface is configured to provide a fluidic connection to a volume of liquid within the liquid storage container when the liquid storage container is connected to the liquid storage container interface; and a safety mechanism actuatable from a first safety mechanism configuration to a second safety mechanism configuration, wherein the safety mechanism is configured to conceal the liquid storage container interface when the safety mechanism is in the first safety mechanism configuration, and wherein the safety mechanism is configured to reveal the liquid storage container interface when the safety mechanism in the second safety mechanism configuration.

Abstract: Embodiments described herein relate to a liquid handling device, comprising: an inlet conduit configured to receive a liquid sample; a first flow path comprising a sample adequacy control chamber in fluidic communication with the inlet conduit, wherein the sample adequacy control chamber is configured to allow the presence or absence of a volume of liquid within the sample adequacy control chamber to be determined; and a second flow path in fluidic communication with the inlet conduit, wherein the second flow path is configured to provide a higher hydraulic resistance than the first flow path.

Abstract: Embodiments described herein relate to a liquid extraction device for extracting liquid from a pierceable liquid storage container, the liquid extraction device comprising: a liquid storage container interface configured to provide a fluidic connection to a volume of liquid within the liquid storage container, the liquid storage container interface comprising a liquid extraction outlet configured to allow liquid to be extracted from the liquid storage container; and a liquid extraction mechanism actuatable from a first configuration to a second configuration; wherein the liquid extraction mechanism is configured to provide a pressure difference between a volume of gas in the liquid storage container and the liquid extraction outlet, when the liquid extraction mechanism is actuated from the first configuration to the second configuration.

Abstract: A pen needle and a method of using the pen needle. The pen needle includes a housing, a needle carrier in the housing supporting a needle, a distal shroud positioned around the needle within the housing, a distal compression spring positioned around the needle between the needle carrier and the distal shroud, a proximal shroud positioned around the needle within the housing, and a proximal compression spring positioned around the needle between the needle and the proximal shroud. The proximal shroud is movable between a first position, in which it engages the distal shroud to hold it in engagement with the housing, and a second position in which the proximal shroud is disengaged from the distal shroud allowing the distal shroud to move in a distal direction to project from the housing and surround the end of the needle.
