Abstract: The breakaway assembly includes a first breakaway subassembly and a second breakaway subassembly. The subassemblies are configured to connect, which causes bellows sheaths in each subassembly to compress and open pores, allowing fluid to flow through the subassemblies. The subassemblies can be connected to luer tip. The luer tips can be connected to the an intravenous (IV) fluid line or other types of lines used in the medical field to move fluids.

Some of the luer tips allow for the quick connection of the luer tip to the subassembly through a flange being inserted into a notch or flange acceptor.
