Abstract
Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a sterile connection for drug delivery. In some embodiments, the fluid coupling devices can be implemented as multi-use, sterile fluid coupling devices that are configured to reduce the likelihood of fluid spillage when being disconnected.
Claims20
A fluid coupling system comprising:
- an insert coupling comprising:
- an insert housing defining an internal space, the insert housing having a front face and an opposite end configured for connection to a first fluid carrying component;
- an insert valve member slidably disposed within the internal space of the insert housing, the insert valve member including a projection;
- an insert seal member attached to the front face of the insert housing and defining a bore;
- and
- an insert spring disposed within the internal space of the insert housing and arranged to bias the insert valve member against the insert seal member such that the projection is within the bore and such that a front face of the insert valve member is planar with a forward-facing surface of the insert seal member;
- and
- a body coupling comprising;
- a body housing defining an internal space, the body housing having a front end configured to receive a front end portion of the insert housing and an opposite end configured for connection to a second fluid carrying component;
- a body stem extending within the internal space of the body housing, the body stem defining a central lumen and a lateral opening in fluid communication with the central lumen;
- a body seal member slidably disposed within the internal space of the body housing, the body seal member defining a bore in which the body stem is slidably received;
- and
- a body spring disposed within the internal space of the body housing and arranged to bias the body seal member to a position in which the bore of the body seal member seals the lateral opening of the body stem and in which a forward-facing surface of the body seal member and a front face of the body stem are planar with each other.

- a body spring disposed within the internal space of the body housing and arranged to bias the body seal member to a position in which the bore of the body seal member seals the lateral opening of the body stem,
- wherein the opposite end of the body housing is engaged with a termination retainer that mechanically attaches the body stem to the body housing, and
- wherein the termination retainer is a cylindrical member that snaps into engagement with the body housing.
