Patent ID: 7846131

Claim:
An administration feeding set for use with a flow control apparatus to deliver fluid from at least one fluid source to a patient, said flow control apparatus comprising a housing, a pumping unit in the housing comprising a rotatable valve shaft, and a closure on the housing movable between an open position and a closed position, the administration feeding set comprising: tubing adapted to extend from said at least one fluid source for flow of fluid through the tubing from said fluid source toward a patient; a valve mechanism in fluid communication with the tubing for controlling flow of fluid in the tubing, said valve mechanism comprising a valve body having a longitudinal axis and an open end; a valve stem in the valve body rotatable relative to the valve body on said axis and accessible through the open end of the valve body for engagement with the valve shaft of the flow control apparatus; an upper sleeve affixed to the valve body and extending up from an upper side of the valve body generally at right angles to said axis for connection to an upper section of said tubing; a lower sleeve affixed to the valve body and extending down from a lower side of the valve body generally at right angles to said axis for connection to a lower section of said tubing; a locating finger affixed to the upper sleeve and projecting laterally outwardly from the upper sleeve for engagement with a locating member on the closure of said flow control apparatus, the locating finger and open end of the valve body being located on opposite sides of the tubing for engagement of the valve stem with the valve shaft of the flow control apparatus and for engagement of the locating finger with the locating member on the closure, and the locating finger being positioned on the upper sleeve so that when the administration feeding set is received on the flow control apparatus in an operating position the finger permits the locating member of the flow control apparatus to close, and when administration feeding set is received on the flow control apparatus in a non-operating position the finger does not permit the locating member to close thereby to verify whether the administration feeding set is in the operating position on the flow control apparatus.
