Seven-year-old Ellie Clark holds her insulin pump, which also works with an implant to display blood sugar levels, Wednesday, Sept. 12, 2007, in Grandville, Mich. Diabetes care is undergoing a transformation. Thousands of patients are switching from a few finger-pricks a day to track their disease to new sensors that keep guard around the clock. The last six months brought big boosts to the technology, as federal health officials approved the first model for children _ one that works for three days in a row _ and the longest-working version yet, a seven-day model for adults. The ultimate goal is to create an “artificial pancreas,” pairing these sensors with insulin pumps that would automatically dispense doses to make a diabetic’s blood sugar more like a healthy person’s.
