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.

First claim

What is claimed is:

1. A fluid coupling device comprising:
a male coupling component including a male coupling shuttle valve member that is slidable along a longitudinal axis of the male coupling component; and
a female coupling component including a female coupling shuttle valve member that is slidable along a longitudinal axis of the female coupling component,
wherein the male and female coupling components are coupleable in a first arrangement in which an open flow path exists through each of the male and female coupling components and in a second arrangement in which: (i) the male coupling shuttle valve member is permanently locked in an end-of-travel position in which the male coupling shuttle valve member blocks flow through the male coupling component and (ii) the female coupling shuttle valve member is permanently locked in an end-of-travel position in which the female coupling shuttle valve member blocks flow through the female coupling component,
wherein the male and female coupling components are only disconnectable from each other while in the second arrangement.

2. The fluid coupling device of claim 1 , wherein while the male coupling shuttle valve member is locked in its end-of-travel position a face of the male coupling shuttle valve member is flush with an end of a bore defined by the male coupling component, and wherein while the female coupling shuttle valve member is locked in its end-of-travel position a face of the female coupling shuttle valve member is flush with an end of a bore defined by the female coupling component.

3. The fluid coupling device of claim 2 , further comprising:
a first seal member positioned between the male coupling shuttle valve member and the bore defined by the male coupling component; and
a second seal member positioned between the female coupling shuttle valve member and the bore defined by the female coupling component.

4. The fluid coupling device of claim 1 , wherein the male and female coupling components are rotatable relative to each other while in the second arrangement between an engaged arrangement and a partly disengaged arrangement.

5. The fluid coupling device of claim 4 , wherein the male and female coupling components can be separated from each other while in the partly disengaged arrangement by translating them longitudinally apart from each other.

6. The fluid coupling device of claim 4 , wherein the male and female coupling components are caused to translate relative to each other as the male and female coupling components are rotated relative to each other between the engaged arrangement and the partly disengaged arrangement.

7. The fluid coupling device of claim 1 , further comprising a locking sleeve movably coupled to the male coupling component, and wherein while the male and female coupling components are coupled in the first arrangement, the locking sleeve is operably coupled with the male coupling shuttle valve member such that a movement of the locking sleeve causes a corresponding movement of the male coupling shuttle valve member.

8. The fluid coupling device of claim 7 , wherein the locking sleeve is slidably coupled to the male coupling component.

9. The fluid coupling device of claim 1 , wherein cross-sectional shapes of the male coupling shuttle valve member and the female coupling shuttle valve member are each circular.

10. The fluid coupling device of claim 1 , wherein the male coupling shuttle valve member and the female coupling shuttle valve member each include one or more apertures through which the open flow path exists.

11. The fluid coupling device of claim 1 , further comprising a removable locking collar releasably coupleable with the fluid coupling device while the male and female coupling components are coupled in the first arrangement.

12. The fluid coupling device of claim 11 , wherein the removable locking collar prevents reconfiguring of the male and female coupling components from the first arrangement to the second arrangement while the removable locking collar is coupled with the fluid coupling device.
