Abstract
An anti-free flow device is disclosed for a fluid administration system having a tube assembly engageable with a pump having one end of the tube assembly connected to a source of fluid and the other end in fluid flow communication with a patient. The valve device comprises a tube portion defining a channel in-line along a portion of the tube assembly and a body disposed and securely retained inside the channel. Fluid flow is initiated through the tube assembly whenever the tube assembly is in a stretched condition, such as when the tube assembly is engaged with the pump. However, fluid free flow is prevented whenever the tube assembly is in a relaxed condition or disengaged from the pump.
