Does anyone know if lines which are longer than the standard are available for nocturnal txs for the purpose of being able to move about more?

I don’t know if there are any. In my program, we just use standard Medisystems tube sets. They seem plenty long enough to me. When you do nocturnal, after you’ve set up the machine, and just before you get ready to put your needles in, you roll the machine right up close up to the bed so you can easily reach the controls. Unless you wanted to move all over a queen size bed, they are long enough. I think they would just get tangled and catch on things if they were longer. For example, they can easily catch under the corners of the machine if they hang down too much. I tape my two bloodlines together so that doesn’t happen.
