In the summer of 2012, Katrina Elisabeth Diel was diagnosed with T1D, and eight months later, she started using the OmniPod insulin pump, made by Insulet, but she never liked how the device looked. “It didn’t look that nice to me,” said the 10-year-old Barrington, RI girl about the device, which is typically worn on the upper arm. “You could see the electrical and computer parts and it looked like a bandage.”

With the help of her father Fred, Katrina recently launched a business called Kedz Covers to sell plastic covers for the OmniPod device in red, blue, beige or green. The covers go for $20 each, and are made under contract by a small, Massachusetts-based plastic molding injection company.

Fred Diel said that the manufacturer was contacted through a friend, and so far, several thousand covers have been manufactured. Some of those have already been delivered. The company already has a Facebook page and Twitter account to help with advertising, and Katrina Diel recently attended a Friends for Life conference for children with diabetes wearing her OmniPod cover, which she said attracted a lot of attention.

Katrina Diel, whose hobbies include dance and swimming, said she likes owning her own company. When asked what she’d like to do when she gets older, she said, “Honestly, I don’t know. I probably would like to have this business.” Kedz Covers donates a portion of the profits from the covers to JDRF, as well as Camp Surefire, a local camp for kids with diabetes.
