  • Patent number: 10207100
    Abstract: The present invention is an injection port with an articulated stopcock allowing a syringe to be connected to an IV line and, depending upon the orientation of the stopcock, allow (1) bidirectional flow of fluid through the stopcock into the IV line, (2) no flow or (3) unidirectional flow of fluid through the stopcock and into or out of the IV line. The invention is particularly useful for using a syringe for aspirating an IV line and then injecting a medicine from the syringe into the IV line. Once a syringe is connected, the invention allows one-handed manipulation of the articulated stopcock into the three orientations by simply moving the connected syringe into one of the three orientations, thereby eliminating the need for using two hands—one to operate the syringe and the other to operate the handle.

  • Patent number: 9138532
    Abstract: A gangable injection port holder including a series of receptacles for receiving swabable access valves that are themselves serially ganged together by tubing or complementary Luer slip connections. The receptacles are integrally formed onto a base with a side wall to allow the swabable access valves during use to be oriented vertically resting on the base or horizontally resting on the side wall. The base may be segmented, with each segment containing at least one of the receptacles. The segments may be easily snapped together in order to quickly assemble the desired number of receptacles intended to be used during a surgical procedure.
