Patent ID: 8827317

Claim:
A medical device adaptor removably connectable to a fitting, the adaptor comprising: a fluid passage extending substantially through the adaptor and configured for fluid connection with the fitting; a mounting port, the mounting port being formed by a substantially cylindrical wall of the adaptor and a ceiling of the adaptor, the ceiling extending substantially perpendicularly from the wall; a mounting shoulder configured to mate with an attachment leg of the fitting extending from the wall; a central axis, the central axis extending substantially centrally through the ceiling; a keyway defined by the ceiling, the central axis passing through the keyway; an insert, the insert defining a thru hole to at least partially align with the fluid passage and wherein the insert defines a key for disposing within the keyway, the key to orientate the insert relative to the fluid passage; and wherein the insert defines a substantially planar sealing surface proximate the thru hole; and a sealing surface configured to form a substantially fluid-tight seal with a corresponding surface of the fitting, the sealing surface remaining substantially fixed relative to the corresponding surface of the fitting when the adaptor is removably connected to the fitting.
