Accuracy Evaluation of a Novel Reusable Patch Pump Prototype

A prototype of an insulin patch pump that operates with a double pump mechanism was tested. Accuracy of bolus delivery of 0.2 U and 1.0 U, and a basal rate of 1.0 U/h were evaluated with a microgravimetric method. In addition, occlusion detection time at basal rates of 0.1 U/h and 1.0 U/h was assessed. Mean deviation from target was lower than 2% for both bolus sizes. Regarding basal rate accuracy, mean deviation over 72 hours was lower than 1%. Occlusion detection occurred in less than 30 minutes with both basal rates. Our study results suggest that the tested pump prototype provides delivery accuracy and occlusion detection that is similar or even better compared to all commercially available pumps tested with a similar experimental approach.

Patient Perspectives on the Benefits and Challenges of Diabetes and Digital Technology

Diabetes technology continues to evolve, advancing with our understanding of human biology and improving our ability to treat people with diabetes. Diabetes devices are broadly classified into the following categories: glucose sensors, insulin delivery devices, and digital health care technology (i.e., software and mobile applications). When supported by education and individually tailored, technology can play a key role in optimizing outcomes. Digital devices assist in diabetes management by tracking meals, exercise, sleep, and glycemic measurements in real time, all of which can guide physicians and other clinicians in their decision-making. Here, as people with diabetes and patient advocates, as well as diabetes specialists, primary care providers, and diabetes care and education specialists, we present our perspectives on the advances, benefits, and challenges of diabetes technology in primary care practices.
