  • Publication number: 20040206924
    Abstract: A medical valve has a translating member that enlarges the volume of the interior of the valve when the valve is in an open mode (permitting fluid flow), and decreases the volume of the interior when the valve is in a closed mode (preventing fluid flow). This varying volume should substantially eliminate drawback into the valve. To that end, the valve includes a housing having an inlet and an outlet, and a fluid channel extending between the inlet and the outlet. The fluid channel includes a variable volume region. The valve further includes the above noted translating member, which is secured to the housing and at least partly bounds the variable volume region. The translating member has at least a portion that moves distally when the valve transitions from the closed mode to the open mode. The distal movement of the translating member enlarges the volume on the variable volume region.

  • Patent number: 6739628
    Abstract: A frangible hose connector that has a knit line at the intended point of fracture, as opposed to a circumferential groove or notch. The knit line provides a break zone which has a lower tensile strength than that of the parent material, thereby providing that the connector is relatively easy to fracture. The connector also includes finger grips which makes breaking the connector easier. The finger grips provide that the connector is configured to be fractured via a twisting or torsion force, as opposed to a bending force. As such, the connector tends to break in a manner wherein fluid does not fling or spray. The connector is formed of plastic, and the knit line is created during the plastic injection molded process, wherein two mold fronts are “squared-up” and meet in the mold cavity to form the knit line.

  • Patent number: 6599273
    Abstract: A fluid transfer device comprising a hollow piercing element having a first end for receiving a standard syringe nose or other similar medical device and a second end having a tapered tip for accessing fluid inside a medication container is disclosed. In a preferred embodiment, the device has a disk-shaped stop for limiting entry of the piercing element into the vial. Preferably, the piercing element includes outwardly extending barbs which allow the device to be inserted into a vial but which prevent the device from being removed from the vial after insertion. After the syringe is disengaged from the device, the device and spent medication vial may be discarded as a unit. Alternatively, the device can remain attached to the vial, and a new syringe can be used to withdraw additional fluid from the vial when desired. In an alternate embodiment, a reusable, resealable valve is connected to the first end of the piercing element, which valve allows multiple syringes to be used with the piercing element.

  • Publication number: 20030120221
    Abstract: The positive flow needleless connector has a cannula slideably mounted within a tubular housing. A sleeve-like septum seals the cannula from an outside environment while also sealing an internal chamber of the cannula from a flow path in a male luer housing. Movement of the cannula from an extended position to a retracted position against the force of a spring exposes a second inlet of the cannula to the flow path of the male luer housing to permit flow therebetween. During disconnect, the inlet from the cannula is sealed prior to the cannula returning the extended position. This allows fluid to move from a reservoir between the cannula and septum to move into the passage of the male luer housing.
