In the United States, about 150,000 people use insulin pumps. Pumps enhance the lives of diabetics by providing flexibility and consistency in insulin treatment. Current pump technology must rely on user input to ascertain the presence and proper seating of an insulin vial. The HMC Clinic team designed and tested a device to automate vial detection and characterization. It is hoped that this technology will be used in the next generation of pumps, enhancing pump versatility and performance.
