Abstract
Fluid coupling devices described herein can used in a bioprocessing facility, for example. In some cases, the fluid coupling devices can be used to couple bioprocessing equipment to a media source in a sterilized environment. The fluid coupling devices can include a two-position valve that is manually actuatable and reconfigurable between a first configuration and a second configuration.
Claims24
A fluid coupling device comprising:
- a main body defining:
- (i) an open internal space, (ii) a valve seat, and (iii) a longitudinal axis, the main body comprising a first fluid conduit connection location and a second fluid conduit connection location;
- an open cylindrical rotary driver that is rotatable relative to the main body;
- a valve member that is reconfigurable along the longitudinal axis between a first configuration and a second configuration, the valve member defining an open internal space and being threadedly coupled with the open cylinder rotary driver;
- a guide sleeve disposed between the open cylindrical rotary driver and the valve member, the guide sleeve defining an open internal space;
- and
- a seal attached to an end portion of the valve member and configured to seal within the valve seat of the main body when the valve member is in the first configuration and within the open internal space of the guide sleeve when the valve member is in the second configuration.

A fluid coupling device comprising:
- a main body defining:
- (i) an open internal space, (ii) a valve seat, and (iii) a longitudinal axis, the main body comprising a first fluid conduit connection location and a second fluid conduit connection location;
- a guide sleeve defining an open internal space;
- a valve member that is reconfigurable along the longitudinal axis between a first configuration and a second configuration, the valve member defining an open internal space and comprising one or more projections;
- a seal attached to an end portion of the valve member and configured to seal within the valve seat of the main body when the valve member is in the first configuration and within the open internal space of the guide sleeve when the valve member is in the second configuration;
- and
- an open cylindrical rotary driver that is rotatable relative to the main body, the open cylindrical rotary driver defining one or more grooves that comprise helical portions and non-helical portions,
- wherein the one or more projections of the valve member are slidably disposed within the one or more grooves of the open cylindrical rotary driver.

A fluid coupling device comprising:
- a main body defining:
- (i) an open internal space, (ii) a valve seat, and (iii) a longitudinal axis, the main body comprising a first fluid conduit connection location and a second fluid conduit connection location;
- a guide sleeve fixedly coupled to the main body and defining an open internal space;
- a valve member that is translatable within the open internal space of the guide sleeve between a first configuration and a second configuration;
- a collar that is rotatable by a user relative to the main body to reconfigure the valve member between the first and second configurations;
- and
- a seal attached to an end portion of the valve member and comprising:
- (i) an annular contoured projection and (ii) a front face,
- wherein the annular contoured projection and the front face seal against the valve seat of the main body when the valve member is in the first configuration, and
- wherein the annular contoured projection seals against the guide sleeve when the valve member is in the second configuration.
