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 reconnected to each other after being disconnected from each other.
Claims20
A single-use aseptic fluid coupling device, comprising:
- a male coupling comprising:
- a male housing defining an internal space and a longitudinal axis;
- and
- a male coupling valve member within the internal space and slidable relative to the male housing along the longitudinal axis of the male housing from an open position to a closed position;
- and
- a female coupling releasably coupled to the male coupling component and comprising:
- a female housing defining an internal space and a longitudinal axis;
- and
- a stem fixedly coupled to the female housing and extending along the longitudinal axis of the female housing, the stem having a front surface facing the male coupling valve member, the stem defining an open bore extending longitudinally and one or more lateral openings fluidly coupling the open bore and the internal space of the male housing such that an open flow path extends through the female coupling and the male coupling while they are releasably coupled to each other;
- an elastomeric seal disposed on the front surface of the stem such that the male coupling valve member is abutting the elastomeric seal.
