Abstract
A fluid connector assembly can be provided that permits ease of connection, secure connection with a fluid connector, and a safety release mechanism that enables the fluid connector assembly to safely disengage from the fluid connector. The fluid connector assembly can include a post and a hub that is slidably coupled to the post. When disconnected from the fluid connector, the hub can be locked or fixed at a lockout position, which can tend to prevent reconnection or reuse of the hub, thereby facilitating safe and sanitary medical practices.
Claims13
A lock-out hub assembly, comprising:
- a two-part post having first and second post components, the first post component being connectable to the second post component at a post joint to form a tubular member having a longitudinal axis, the first post component comprising a guide mechanism disposed along an exterior surface thereof, the second post component comprising a stopper mechanism disposed along an exterior surface thereof;
- and
- a hub comprising an engagement component and a central lumen that is alignable with the longitudinal axis of the tubular member and configured to permit the first post component to be positioned therethrough when the first and second post components are in a disconnected state, the hub further comprising an alignment mechanism for engaging with the guide mechanism of the first post component for restricting rotational movement of the hub relative to the first post component when the hub is coupled to the first post component, the hub being restricted from longitudinal movement relative to the second post component by the stopper mechanism of the second post component when the first and second post components are connected together in a joined state.
A method of assembling a lock-out hub assembly, the method comprising:
- inserting a first post component into a central lumen of a hub;
- engaging a guide mechanism of the first post component with an alignment mechanism of the hub for restricting rotation of the hub relative to the first post component;
- and
- coupling a second post component to the first component to form a post joint, the second post component having a stopper mechanism configured to limit longitudinal movement of the hub along a longitudinal axis of the first and second post components.
