Problems solved by technology

Currently available ambulatory infusion devices are expensive, difficult to program and prepare for infusion, and tend to be bulky, heavy and very fragile.
Preparing these devices for infusion can be difficult and require the patient to carry both the intended medication as various accessories.
Due to the complexity and high cost of existing devices many patients who would benefit from an ambulatory infusion pump are, nonetheless using inferior forms of therapy.
