MEDICAL DEVICE INTERFACE SYSTEM

摘要

An interface device secures an instrument to a docking station. A rail cam forms part of the instrument housing. The rail cam secures the instrument housing to a mounting rail mounted to a surface. The rail cam includes a cam base having a surface with the base mounted for pivotal movement relative the remainder of the instrument housing. The rail cam also includes two opposing arms near the periphery of the cam base. The arms extend substantially perpendicular relative the surface of th e cam base with each arm having an arm base defining a lock surface. The arms are positioned on the cam base such that the distance between the two lock surfaces is substantial ly equal to the height of the mounting rail. The rail cam further includes a guiding portion at the top of each arm base for contacting the mounting rail during insertion of the rail cam onto the mounting rail and transferring the force of contact with the mounting rail t o the cam base. This serves to induce rotation of the rail cam from a closed/lock position t o a opened/receive position during which the rail cam receives the mounting rail . Subsequently removal of the force from the cam base allows rotation of the rail cam from the open/receive position to the closed/lock position during which the rail cam retains the mounting rail.
