Abstract
Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a single-use, aseptic disconnection functionality that substantially prevents fluid spillage when being disconnected. In some embodiments, the coupling portions cannot be functionally reconnected to each other after being disconnected from each other.
Claims20
A single-use aseptic fluid coupling assembly defining a longitudinal axis and an open fluid flow path through the fluid coupling assembly along the longitudinal axis, the fluid coupling assembly comprising:
- a first coupling comprising:
- a first housing;
- a first termination member fixedly coupled to the first housing and including a first termination;
- a shell that is rotatably coupled to the first housing;
- a first valve that is fixedly coupled to the first termination member;
- and
- a shuttle disposed about the first valve, the shuttle being coupled to the shell such that the shuttle is translatable along the longitudinal axis in response to rotation of the shell;
- a valve gasket coupled to the first valve;
- and
- a second coupling releasably connected to the first coupling and comprising:
- a second housing;
- a second termination member fixedly coupled to the second housing and including a second termination;
- and
- a second valve movably coupled to the second termination, the second valve being translatable along the longitudinal axis relative to the second termination,
- wherein a face seal portion of the valve gasket is compressed between a face portion of the first valve and a face portion of the second valve.
A single-use aseptic fluid coupling assembly defining a longitudinal axis and an open fluid flow path through the fluid coupling assembly along the longitudinal axis, the fluid coupling assembly comprising:
- a first coupling comprising:
- a first housing;
- a first valve;
- and
- a shell that is rotatably coupled to the first housing;
- and
- a second coupling releasably connected to the first coupling and comprising:
- a second housing;
- and
- a second valve, the second valve being translatable along the longitudinal axis,
- wherein manual rotation of the shell drives closure of the first and second valves and physical separation of the first and second couplings.
