"I find these little 6" Saline Locks great for backcountry, extrication or any place where you want to maintain a nice, unincumbered IV site. You don't always need IV tubing flopping around or getting caught/hung up while you're trying to extricate your patient! These little Saline Locks will maintain a readily available access site and can be easily secured without the fear of getting tangled or caught on something. I highly recommend having several in you IV bag!"
