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 method of using a fluid coupling system, the method comprising:
- advancing a male coupling device into a female coupling device, wherein the male coupling device comprises:
- a housing defining an internal space;
- a valve member slidably disposed within the internal space of the housing, the valve member comprising a projection;
- a seal member attached to the housing and defining a bore, wherein a portion of the seal member and a portion of the projection each protrude outside of the internal space;
- and
- a spring disposed within the internal space of the housing and arranged to bias the valve member against the seal member;
- and
- engaging the male coupling device with the female coupling device to releasably latch the male and female coupling devices.

A method of using a fluid coupling system, the method comprising:
- advancing a male coupling device into a female coupling device, wherein the female coupling device comprises:
- a housing defining an internal space;
- a valve stem extending within the internal space of the housing, the valve stem defining a central lumen;
- a seal member slidably disposed within the internal space of the housing, the seal member defining a bore in which the valve stem is slidably received;
- and
- a spring disposed within the internal space of the housing around the valve stem, the spring arranged to bias the seal member to a closed position in which the bore of the seal member surrounds part of the valve stem to thereby exclusively seal the central lumen closed;
- and
- engaging the female coupling device with the male coupling device to releasably latch the female and male coupling devices.
