  • Patent number: 9388929
    Abstract: A male bayonet connector connects a section of tubing to a female latch connector. The male bayonet connector includes a shaft defining a lumen, a distal end portion, and a proximal end portion. The distal end portion of the shaft has a sealing surface configured to engage a seal member within the female latch connector to create a fluid-tight seal. The shaft defines an annular recess proximal to and adjacent the distal end portion. The annular recess has a proximal chamfered side wall and a distal sidewall perpendicular to the axis of the lumen, which are separated by a band of smaller diameter than the sealing surface. A grip is formed on the male bayonet connector between the proximal end portion and the annular recess. A ratio of a length of the first sealing surface to a distance between the grip and the distal sidewall is such that a side-load force, as imparted on the male bayonet connector, will not break a fluid-tight seal between the sealing surface and the seal member.

  • 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: 8113546
    Abstract: A latching female tubing coupler comprises an opening, a collet finger, and an actuation member. The opening is adapted to guide a male connector along a first line of action as the male connector passes into the opening to be received within the latching female tubing coupler. The collet finger includes an engagement feature adapted to engage a coupling feature of the male connector and displace along a second line of action generally normal to the first line of action. The actuator member is adapted to displace along a third line of action generally normal to the first and second lines of action in order to disengage the engagement feature from the coupling feature of the male connector. When the engagement feature is engaged with the coupling feature on a male connector, a fluid conduit of the male connector is held in fluid communication with a fluid conduit of the latching female tubing coupler.

  • 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.
