Split ring assembly for an airless rotatable connector

摘要

A rotatable connector having an enlarged annular flange positioned at the distal end of a tubular body. An annular cap having an aperture is received on the tubular body through the aperture so as to rotatably encircle the tubular body proximal of the retaining flange. A split ring rotatably encircles the tubular body between the retaining flange and the cap. The split ring has an inner diameter smaller than the outer diameter of the retaining flange and an outer diameter larger than the inner diameter of the aperture of the cap. An access chamber positioned at the proximal end of a tubular hub receives the distal end of the tubular body in mating relationship to enable the proximal end of the hub to be ridgedly coupled to the cap. A transfer duct communicating with the access chamber in the tubular hub is rotatably fluid coupled with the passage in the tubular body.
