  • Publication number: 20150034194
    Abstract: A medical connector assembly for establishing a fluid connection between a first medical device and a second medical device includes a multi-use connector and a plurality of single-use connectors connected in series. The multi-use connector has a proximal end opposite a distal end along a longitudinal length thereof. The plurality of single-use connectors each have a proximal end opposite a distal end along a longitudinal length thereof. The distal end of the multi-use connector is releasably connected to the proximal end of a first of the serially-connected single-use connectors. When a second of the serially-connected single-use connectors is disconnected from the first single-use connector, the first single-use connector remains connected to the multi-use medical connector as a sterility retaining cover.

  • Publication number: 20140276411
    Abstract: A fluid delivery system includes a pressurizing mechanism. The pressurizing mechanism includes: a substantially cylindrical body having a movable member positioned therein that divides the body into a first chamber and a second chamber; a plunger rod connected to a first side of the movable member and extending through a substantially closed first end of the body; and an elongated member connected to a second side of the movable member and extending through a substantially closed second end of the body. The plunger rod configured to operatively engage a fluid container. Fluid is dispensed from the fluid container by forming a vacuum within at least the first chamber by moving the movable member toward the second end of the body, allowing atmospheric pressure to enter the second chamber, and actuating the pressurizing mechanism to cause the moving member to move towards the first end of the body.
