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.
Claims18
A single-use aseptic fluid coupling device, comprising:
- a male fluid coupling comprising a male valve in an open position;
- a female fluid coupling comprising a female valve in an open position, wherein the female fluid coupling is releasably coupled to the male fluid coupling to define an open fluid flow path therethrough;
- and
- a member removably attached to the male and female fluid couplings to prevent the male and female fluid couplings from being rotated relative to each other and from being moved longitudinally relative to each other, wherein the member comprises a longitudinal rib that mechanically engages the male and female fluid couplings to prevent the male and female fluid couplings from being rotated relative to each other,
- wherein the single-use aseptic fluid coupling device is configured to require movement of the male and female fluid couplings away from each other to reconfigure the male and female valves from the open positions to closed positions,
- wherein the member is removable from the male and female fluid couplings to allow the male and female fluid couplings to be uncoupled from each other, and
- wherein, after the male and female fluid couplings are uncoupled from each other, the male and female fluid couplings cannot redefine the open fluid flow path therethrough by being recoupled.

- a member removably coupled to the male and female couplings to prevent the male and female fluid couplings from being rotated relative to each other and from being moved longitudinally relative to each other,
- wherein the single-use aseptic fluid coupling device is configured such that the open fluid flow path closes as the male and female fluid couplings are moved away from each other, and
- wherein the male and female couplings are configured to require longitudinal movement toward each other in order to uncouple them from each other.
