  • Patent number: 6902207
    Abstract: Apparatuses and methods for connecting and disconnected fluid conduits (e.g. medical tubing) are disclosed. Typical embodiments of the Apparatuses and methods disclosed herein operate with two separate components, the first having a moveable septum and the second having a fixed septum. When the components are engaged, the device allows the flow of fluid through a conduit to which they are coupled. When the components are uncoupled, the device prevents the flow of fluid through the conduit. An exemplary embodiment of the invention includes a housing, a moveable septum slideably coupled with the housing to be alternately disposed in at least a first and second position and a piercing member having a passage for conducting fluid. The moveable septum closes the passage in the first position and is penetrated by the piercing member to open the passage in the second position.

  • Publication number: 20040227120
    Abstract: A self-sealing male connector having a body, a resilient boot mounted over the body, and a male thread hub. The body is formed with an elongate post that extends to the distal end. The body includes a fluid flow lumen extending from its proximal end to its distal end. At its proximal end, the body may be formed as a female Luer connector, or may be directly connected to tubing, or other arrangements. The internal fluid flow lumen extends through the post to its distal end. The body includes a first groove in which is mounted the boot. In a second groove is mounted the thread cuff. The thread cuff is used to engage a female connector and through thread action, draw in into engagement with the post. As the female connector is further engaged with eh sealed male connector, the post protrudes through the boot and into fluid communication with the female fluid flow passage thus establishing a flow path through both connectors.

  • Publication number: 20040220532
    Abstract: A medical device having a releasable retaining includes needle cannula connected to a hub having an open proximal end with a frusto-conically shaped cavity therein. The cavity is part of a passageway through the hub which is in fluid communication with the lumen of the needle cannula. A retaining element is releasably connected to the hub. The hub includes an aperture and at least one protuberance projecting into the aperture for engaging the frusto-conically shaped tip of a fluid delivery device. The protuberance is shaped to offer less resistance to hub movement in a direction of engagement than in a direction of disengagement with the tip. The retaining element is connected to the hub so that when the hub is engaged to the tip, the force required to disengage the retaining element from the tip is greater than the force required to disengage the retaining element from the hub.
