Abstract
A safety interlock system for a flow control apparatus is disclosed that permits operation when a magnet-less administration feeding set is properly mounted to recess formed along the housing of the flow control apparatus. The administration feeding set comprises flexible patient tubing having a support member at one end and a mounting member including a magnetically-susceptible metallic component at the other end thereof. A sensing arrangement is provided by the flow control apparatus for sensing the proper engagement of the metallic component to the recess of the flow control apparatus. A control means permits operation of the flow control apparatus when the metallic member is properly engaged to recess, while terminating operation when the metallic member is improperly engaged to recess.
