My dad tried out a 24/7 IV for a heart medicine. The pump and a bag with a 1 week supply of the medicine fit in a fanny pack sized bag. It worked well, but he's 90 and pulled out the IV line in the middle of the night. He didn't remember doing it. So we decided to discontinue the meds. But I'm sure it would have been fine for a younger, less confused person. Just a bit inconvenient for showering, etc.
