Abstract
Fluid handling couplings can be configured for use in sterile fluid systems. For example, this document describes fluid handling couplings that are sterilizable, genderless, that include manually openable valves, and that are configured for single-use aseptic fluid handling usage. The manually openable valve can include a screw thread segment and a plug portion. The plug portion can block fluid flow through the fluid handling coupling when the valve is in its closed configuration.
Claims16
A fluid coupling device comprising:
- a main body defining a central longitudinal axis, a seal recess, and an internal space, the main body comprising a front face;
- a seal comprising a seal portion disposed within the seal recess and a seal portion projecting from the front face, the seal defining a longitudinally-extending central passageway;
- a membrane removably adhered to the front face and covering the seal portion projecting from the front face;
- a valve actuator rotatably coupled to the main body;
- a termination member fixedly coupled to the valve actuator, the termination member comprising a fluid connector end extending away from the main body and an opposite end portion that is disposed within the internal space and that defines a thread groove;
- and
- a valve member slidably translatable along the central longitudinal axis within the internal space, the valve member being prevented from rotating about the central longitudinal axis, the valve member comprising:
- (i) a screw thread segment slidably disposed in the thread groove of the termination member and (ii) a plug portion that is sized to engage within the central passageway of the seal to block fluid flow therethrough.
