Abstract: A flow battery reservoir includes a reservoir housing, an electrolyte inlet configured to provide an electrolyte mixture containing a liquid metal-halide electrolyte solution and a complexed halogen phase at or toward a stagnant zone in a lower portion of the reservoir, and an electrolyte outlet configured to outlet the liquid metal-halide solution from the reservoir. The electrolyte outlet is positioned such that in use the liquid metal-halide solution flows upward against the force of gravity to reach the electrolyte outlet while the complexed halogen phase settles in the stagnant zone.

Abstract: A flow battery and method of operating a flow battery. The flow battery includes a first electrode, a second electrode and a reaction zone located between the first electrode and the second electrode. The flow battery is configured with a first electrolyte flow configuration in charge mode and a second flow configuration in discharge mode. The first electrolyte flow configuration is at least partially different from the second electrolyte flow configuration.

Abstract: A single-use auto-disable syringe device utilizes a locking element to prevent re-use of the syringe by locking the plunger rod with respect to the barrel upon completion of an injection stroke. The plunger rod includes a plurality of teeth comprising distally facing shoulders provided on a majority of the length of an elongate portion of the plunger rod.

Abstract: A cannula insertion device is disclosed. The device includes a needle carriage, a rail device on which the needle carriage is slidable, a yoke having a channel, a linkage connected to the needle carriage and extending into the channel, a torsion spring with one end connected to the linkage, and locking device for locking the torsion spring in tension and maintaining the needle carriage and the linkage in a locked position prior to activation. Upon release of the locking device, the tension of the torsion spring is released, which causes the linkage to move in the channel and slide the needle carriage along the rail device. A catheter carriage may also be provided for actuation by the linkage.

Abstract: Embodiments of a retractable syringe assembly are provided that include a single syringe barrel configuration and dual syringe barrel configuration. In one or more embodiments, the assemblies include a barrel having a dividing wall to divide the chamber to define a fluid chamber having a first cross-sectional width for retaining fluid and a needle chamber for housing a needle hub assembly. The assemblies include a projection extending radially outwardly from the plunger rod to interact with a ramped portion of the dividing wall to cause the needle cannula to retract and be housed within the needle chamber.

Abstract: An infusion set adapted to be secured to a skin surface includes a fixed base member connectable to the skin surface and a movable member. A needle or cannula is connected to the movable member and movable relative to the fixed base member. The movable member is movable from a first position in which the needle or cannula is not exposed externally of the fixed base member to a second position in which the needle or cannula is exposed externally of the fixed base member. A release member retains the movable member in the first position. Removal of the release member allows movement of the movable slide member to the second position.

Abstract: Embodiments of a retractable syringe assembly are provided that include a dual syringe barrel configuration. In one or more embodiments, the assemblies include a fluid barrel for retaining fluid and a retraction barrel for housing the retraction feature and the needle hub assembly. The assemblies include a trigger element that moves with the plunger rod to activate the retraction feature within the retraction mechanism.

Abstract: A flow battery includes a stack of flow cells, a stack of cell frames supporting the stack of cells, stack level and cell level flow manifolds located in the stack of cell frames, and at least one sealing or shunt current mitigation feature.

Abstract: An infusion set is disclosed that includes an inserter including an inserter housing having at least one flexible arm for holding an infusion set in a single axial position prior to insertion of at least a portion of a cannula of the infusion set, the inserter housing having a surface for contacting the patient's skin. The inserter also includes a movable plunger disposed within the inserter housing for releasing the infusion set from the inserter housing, impacting the infusion set, and imparting momentum to the infusion set to insert the cannula into the patient's skin. The inserter additionally includes a biasing element biasing the plunger toward the activated position.

Abstract: A single-use auto-disable syringe device of reduced size utilizes a locking element to prevent re-use of the syringe by locking the plunger rod with respect to the barrel upon completion of an injection stroke. The plunger rod includes a plurality of teeth comprising distally facing shoulders provided on a majority of the length of an elongate portion of the plunger rod and a breakable section configured to break upon the application of excessive axial or torsional force. The breakable section is preferably provided at a distal end of the plunger rod so that a proximal end of the locking element engages the syringe barrel and plunger rod at a position more proximal than the breakable section. In this way, the locking element resists some of the force that would otherwise be applied to the breakable section if the plunger rod were twisted.
