Abstract
This document describes fluid handling couplings. For example, this document describes fluid handling couplings that include manually openable valves and that are configured for aseptic fluid handling usage. In some embodiments, the valves are manually openable by rotation of a collar of the fluid handling couplings.
Claims8
A fluid coupling device comprising:
- a main body defining a longitudinal axis and including a front face that defines an opening to an interior space defined by the main body;
- an aseptic attachment structure at a first end of the fluid coupling device and including a membrane that is removably attached to the front face and covering the opening to the interior space;
- a collar that is rotatably coupled to the main body, the collar including a projection extending radially inward;
- a valve shuttle member, at least a portion of the valve shuttle member being disposed between the collar and the main body, the valve shuttle member defining a groove in which the projection is slidably disposed such that manual rotation of the collar drives translation of the valve shuttle member along the longitudinal axis;
- and
- a termination member coupled to the main body at a second end of the fluid coupling device that is opposite of the first end,
- wherein the main body includes two radially outward extending projections, and wherein the collar includes four flexible collar portions that each interface with the two radially outward extending projections as the collar is rotated relative to the main body.
