Abstract
A cassette with free flow prevention for use with an ambulatory pump. The cassette includes a free flow prevention clamp and a housing. The free flow prevention clamp includes a clamping section having a first side and a second side, a first elongate section extending from the first side, and a second elongate section extending from the second side. The housing supports the free flow prevention clamp and defines a channel for receiving a tube. The elongate sections extend parallel to the channel and the clamping section extends across the channel. The free flow prevention clamp is configurable within the housing in an open condition that allows fluid flow through the tube when force is applied to one of the elongate sections and in a closed condition that prevents fluid flow through the tube when the force is removed from the elongate sections.
