    Abstract: A dual chamber syringe facilitates selective drug mixing, dosing, and administration, as well as pre- or post-administration flushing with a single syringe instrument. A syringe barrel incorporates an outlet, as well as variable-volume, primary and secondary fluid chambers, separated by a floating stopper. The floating stopper defines a dome-shaped split septum with a central slit at its apex. The split septum is a bi-stable valve, closing the central slit by compression in its meridial dimension when the septum is in a first, relaxed state, and opening the central slit when the septum is buckled or flipped under tension in the meridial dimension in a second state. Buckling of the septum wall is caused solely by differential fluid pressure applied by a single plunger, without physical contact of the septum with any other structure within the syringe.

    Abstract: A cap configured to engage a first connector and a second connector of different types includes a housing having a first end, an open second end, a sidewall extending therebetween, and a radially extending flange extending outward from the sidewall or open second end. The cap also includes an absorbent member disposed in the housing configured to contain a cleaning solution for cleaning and/or disinfecting portions of the first connector or the second connector engaged to the cap. The housing is configured to move between a first position, in which the housing is configured to engage the first connector, and a second position, in which the housing is configured to engage the second connector, by folding over the sidewall of the housing such that, in the second position, the flange surrounds a portion of the sidewall between the first end and the second end of the housing.
