Flow control devices and methods using the flow control devices are provided. In a general embodiment, a cassette includes a housing having a constrictor, a tube attached to the housing and positioned through the constrictor, and a ball positioned inside the tube. The constrictor can be constructed and arranged to prevent the ball from moving through the tube at the location proximate the constrictor. The ball can prevent fluid flow in one position and be dislodged to allow fluid flow when the cassette is positioned inside a pumping device. As a result, the cassette is designed to prevent free flow of fluid when an enteral feeding tube set is not installed in a pumping device.

Flow control devices and methods of using the flow control devices are provided. In a general embodiment, the present disclosure provides a cassette () comprising a housing () having a constrictor (), a tube () attached to the housing and positioned through the constrictor, and a ball positioned inside the tube. The constrictor can be constructed and arranged to prevent the ball () from moving through the tube at the location proximate the constrictor. The ball can prevent fluid flow in one position and be dislodged to allow fluid flow when the cassette is positioned inside a pumping device. As a result, the cassette is designed to prevent free flow of fluid when an enteral feeding tube set is not installed in a pumping device.

The present disclosure provides cassettes and methods of using same for the delivery of fluids to a patient using fluid delivery systems. In a general embodiment, the cassettes of the present disclosure include a flexible tube, a housing having a recessed area and first and second ends for holding the flexible tube, and at least two additional components including, for example, different sensors, false reading components for sensors, anti-flow valve means, insertion guides, directional indicators, latch mechanisms, kink-prevention notches, etc. Such additional components provide the cassettes of the present disclosure with several advantages including, for example, quality control, efficiency of use, cost effectiveness, and safety of use.
