Longitudinal Port Patents (Class 285/70)
  • Patent number: 11009166
    Abstract: The invention relates to a locking coupling including a first coupling unit and a second coupling unit, which in each case extend along a longitudinal axis and are designed to be identical. Each coupling unit includes a valve unit and a locking unit. The first and the second valve unit are designed to form a fluid connection between the first and the second coupling unit, and the first and the second locking unit are designed to connect the first coupling unit and the second coupling unit mechanically to one another. The first coupling unit includes an actuating element, by actuation of which the first and the second coupling unit can be mechanically connected to one another via the first and the second locking unit and can be fluidically connected to one another via the first and the second valve unit.

  • Patent number: 10180153
    Abstract: A device includes first and second inter-engageable parts, each having a longitudinal axis and a connecting face extending substantially transversely to the longitudinal axis. The first part has an engagement formation extending substantially axially and the second part has a receiving formation extending substantially axially, and in which the engagement formation is receivable. The engagement and receiving formations each includes a substantially helicoidal surface extending at least partially around the longitudinal axis of the respective part of the connector, so that rotation of the parts relative to one another about the longitudinal axes, when the parts are substantially co-axially aligned, so that the connecting faces of the parts face one another in a substantially axial direction, causes engagement of the engagement formation with the corresponding receiving formation.

  • Patent number: 10107435
    Abstract: A coupling includes an engagement face included in an engagement hook which is set at an angle in a range where the engagement face is still inclined at a positive angle, which is maintained when the coupling and a counterpart coupling are in a coupling state, even if a fluid leaks as a result of opening a sealing portion of the couplings, at a state where the coupling state is maintained, or even if a hose or the like fitted to the coupling bursts when high pressure is applied to the coupling, the hose, etc., while in use.

  • Patent number: 9423062
    Abstract: A connector assembly may be formed by the combination of a latch member and a connector member. The latch member has an annular collar and an arcuate latch wall extending from a circumferential edge of the annular collar. A latch recess and a latch arm are defined within the latch wall. A wing grip extends from an exterior surface of the latch wall adjacent the latch recess and is configured to reinforce the latch arm by countering a tendency of the latch arm to flex radially outward when the connector assembly is subject to a tension load along a longitudinal axis of the connector assembly. A plurality of snap arms are arranged about a circumference of the interior surface of the annular collar to engage the connector member. The connector member receives and retains the latch member directly about an outer male insertion surface thereof rather than passing a barbed end of the connector member through the latch member.

  • Publication number: 20080277878
    Abstract: A method and a device are provided for contamination-free and/or sterile sealing between two interconnectable connecting means having opposing openings. Interconnection allows transfer of a fluid between the openings. Sealing elements are arranged on the connecting means around the openings, and protective films are provided, covering the sealing elements and the openings and adapted to be removed in the final interconnection. The sealing elements are each provided with at least one recess which extends wholly or partly around the associated opening and receives a gas. In use the sealing elements are moved into engagement with each other, interleaved with the protective films, to reduce the volume of the recesses and, thus, increase the pressure of the gas therein. During removal of the protective films, the gas flows out of the recesses to the environment to prevent penetration of contamination into the openings.

  • Publication number: 20030030272
    Abstract: An apparatus for establishing aseptic/sterile connections including a substantially flexible, substantially transparent sterile barrier enclosing a terminal end of a conduit and a resilient, deformable support card which further includes an adhesive perimeter covered by a release paper and a rolling membrane with a continuous, removable, yieldable, flexible strip material is disclosed. A portion of the rolling membrane is removably adhered to the support card and overlies the end of said conduit. A force applied to the free end thereof withdraws the entire rolling membrane to expose the end of said conduit whereby an aseptic/sterile connection is achieved by adhering opposing support cards together, removing said rolling membrane thereby creating a sterile corridor between a first sterile barrier and a second sterile barrier, and mating the terminal end of a first conduit and a second conduit together.

  • Patent number: 6394032
    Abstract: The present invention relates to a device for simulating static load of a connection to a ventilated rack of animal cages when at least one of the racks are not connected to a central ventilation system. Accordingly, the device assures that the ventilation system is balanced when one or more of the ventilated racks are removed from their respective air supply or exhaust drops of the central ventilation system. The device includes a pair of spring biased legs which automatically close when a rack is removed from the central air system. The legs have an outwardly curved shape at one end forming an opening between the first and second leg. In the closed position, ends of the legs are adjacent to one another such that the distance between the legs is reduced, thereby creating a partial obstruction to air flow in the connection which is identical to the static load created by the ventilated rack.

  • Patent number: 4418945
    Abstract: Sterile connectors which utilize tabs or strips, portions which can be withdrawn from apertures which are to be interconnected in sterile fashion are disclosed. The connectors disclosed are utilized in conditions of differential pressure between the inside of conduits to which the connectors are coupled and the surrounding ambient. Contamination resulting from air flow due to the pressure differential is prevented by encasing the tab or strip in a sleeve or extension which isolates the strip or tab from the surrounding ambient. When a pair of sterile connectors is mated, deformable washers are brought into contact and the tabs or strips are pulled through channels in the washers into the sleeves or extensions while portions of the washers remain in contact forming an hermetic seal.

    Abstract: An improved hermaphroditic multiple connector plug having a front or mating end, and a back or cable end, comprising a cylindrical body having a contact assembly, including means to support a plurality of electrical contacts. The contact assembly surrounds and is sealed to the body, and has projections adapted to mesh with the corresponding projections on the contact assembly of a mating plug, so as to relatively index the two plugs and their contacts. The plug has a cylindrical tubular locking ring with diametrically disposed extensions which mesh with the extensions of the locking ring on a mating plug. There are sloping grooves and ridges on the projections so that as the locking ring is rotated clockwise with respect to a locking ring on a mating plug, the two plugs will be pulled and locked together. When the locking rings are turned counterclockwise with respect to each other, cam surfaces on the ends of the projections act to unlock and separate the two plugs.
