A method for filling a reservoir a filling assembly having a needle, and a fluid. The reservoir is in a disposable housing assembly with a septum fluidly connected to the reservoir, a septum access assembly having a first position covering the septum and a second position providing access to the septum, and a bias mechanism for biasing the septum access assembly to the first position. The method includes piercing the septum with the needle, inserting fluid to the reservoir through the needle, contacting the filling assembly to the septum access assembly, and removing the needle from the septum. Removing the needle from the septum allows the bias mechanism to move the septum access assembly from the second position to the first position. The disposable housing assembly is attached to a reusable housing assembly.

A fill adapter for filling a reservoir and a related method are disclosed herein. The fill adapter includes a button assembly actuator and a pump chamber plunger actuator hingeably attached to the button assembly actuator, wherein the actuation of the button assembly actuator actuates the pump chamber plunger actuator and wherein the pump chamber plunger actuator actuates a pump chamber membrane before the at least one button assembly is actuated.

Systems and methods for shielded fluid transfer are provided. A fluid transfer shield is provided to facilitate transferring fluid from a first container to a secondary container. The fluid transfer shield includes a shield having an exterior and defining an interior space, a first port extending from the exterior of the shield, the first port configured to be fluidly coupled to the first container, and a second port extending opposite the first port and into the interior space of the shield so that the shield laterally surrounds the second port, the second port configured to be fluidly coupled to the secondary container. A passageway is provided that extends between the first port and the second port to fluidly couple the first container and the secondary container when the first container is fluidly coupled to the first port and the secondary container is fluidly coupled to the second port.

A tissue expander having an integrated drain includes a shell having an opening and one or more drainage holes, and an injection port disposed in the opening of the shell and forming a fluid-tight seal with the shell. The injection port includes a needle guard having a needle guard base with a top surface. The injection port includes a moveable barrier membrane overlying the top surface of the needle guard base. The moveable barrier membrane is moveable between a first position for inflating and deflating the shell with a first fluid and a second position for draining a second fluid from outside the shell. A magnet is coupled with the moveable barrier membrane, and a compressible spring is connected with the magnet. The compressible spring is compressed for storing energy as the moveable barrier membrane moves from the first position to the second position.

A multi-dose disposable fluid delivery system includes at least one fluid container, a multi-use fluid path set, and a plurality of single-use fluid path sets. The at least one fluid container has a connection port configured for fluidly connecting with a first end of the multi-use fluid path set. The second end of the multi-fluid path set is configured for fluidly connecting to a fluid injection apparatus. The plurality of single-use fluid path sets is connected in sequence to define a fluid path extending from a first single-use fluid path set to a last single- use fluid path set. Each of the plurality single-use fluid path sets has a first end and a second end. The first end of the first single-use fluid path set is configured for connecting to a delivery line. The second end of the last single-use fluid path set is configured for connecting to the injection apparatus.

A self-cleaning needleless connector may include a connector body defining a fluid passageway including an inlet and an outlet, a cover disposed over at least the inlet of the connector body, an access point disposed at an inlet end of the cover, where in a first position the inlet is within the cover and in an second position the inlet is extended beyond the cover and configured to receive a male luer, a reservoir containing a cleaning agent, and an abrasive surface located in the cover that is in fluid communication with the cleaning agent, where the abrasive surface and the cleaning agent are configured to contact an exterior surface of the inlet to create friction.

A disposable patch pump may be provided with a filling adapter, to ensure filling by an authorized user. The adapter mates with the pump and a source of medicament, such as an insulin vial, to prevent filling the pump directly with a conventional syringe. The adapter and/or pump filling port may be configured with a frangible element, to limit the system to single use.

A filling aid device for filling a reservoir. The device includes a cover portion comprising a septum window; a slider beam comprising a septum cover; and a first filling aid tab attached to the slider beam, the first filling aid tab in slidable relation to the cover from a first position to a second position, wherein when the filling aid device is in an unlocked position, the septum cover is located below the septum window, wherein when the first filling aid tab is moved from the first position to the second position, the septum cover is moved from below the septum window, and the filling aid device is in the locked position.
