I haven't been around lately due to a job change and moving, but I could use some help. Has anyone ever been able to unclog tubing? I've been able to unclog a steel set before with a syringe and a lot of pressure but when I tried doing it on the tubing there was too much resistance and eventually just leaked where I'd stuck the syringe in. Normally, I'd think heat might help, but I think heat makes insulin crystallize more so I'm not sure. I don't need perfect solutions or things you'd do on a regular basis, I'm looking for a way out of a one time bind. I'm looking for either experience or assistance brainstorming this particular problem, not advice to call the manufacturer or bring more supplies with you. I have enough experience that this is a major inconvenience but not an emergency.
