  • Patent number: 8397756
    Abstract: A fluid conduit coupling assembly has a depressible latch mechanism that secures a first fluid conduit to a second fluid conduit via a first coupler and a second coupler. The first coupler connects to the first fluid conduit and the second coupler connects to the second fluid conduit. The depressible latch mechanism is formed by a pair of cantilevered buttons disposed in symmetrically opposed positions on one of the couplers. The cantilevered buttons have engagement lips that extend distally with catches that extend radially outward to engage a ridge formed on an interior wall of the opposing coupler. Fluid ports within the couplers interface when the couplers connect to provide fluid flow between the first and second conduits. Valves may be disposed in each of the couplers to arrest fluid flow when the couplers are detached and automatically open to allow fluid to flow when the couplers are connected.

  • Patent number: 7806139
    Abstract: The present invention is a fluid conduit coupling assembly for coupling a first fluid conduit to a second fluid conduit. The fluid conduit coupling assembly comprises a first coupler and a second coupler. The first coupler is for connecting to the first fluid conduit and comprises a first housing and a first valve. The first valve comprises a first lever arm. The second coupler is for connecting to the second fluid conduit and comprises a second housing and a second valve. The second valve comprises a second lever arm. When a force is applied to couple together the couplers, at least a portion of said force is communicated to each lever arm, thereby causing each valve to pivot from a closed position to an open position. The first valve and first lever arm are contained within the first housing, and the second valve and second lever arm are contained within the second housing.
