Abstract

An administration feeding set for use with a flow control apparatus to deliver fluid from at least one fluid source to a patient. The feeding set includes tubing adapted to extend from the fluid source for flow of fluid through the tubing from the fluid source toward a patient. A locating finger projects outwardly from the tubing and is positioned on the tubing so that when received on the flow control apparatus in an operating position the finger permits a locating member of the flow control apparatus to close. However, when the tubing 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 tubing is in the operating position on the flow control apparatus.
