| Sumario: | Paul Vereshchetin, Thomas W McCann Jr, Navdeep Ojha, Ramakrishna Venugopalan, Brian L Levy Johnson & Johnson Diabetes Care Companies, Chesterbrook, PA, USA Abstract: The role of continuous subcutaneous insulin infusion (insulin pumps) has become increasingly important in diabetes management, and many different types of these systems are currently available. This exploratory study focused on the reported heating issues that lithium-ion battery-powered pumps may have during charging compared with battery-operated pumps. It was found that pump temperature increased by 6.4°C during a long charging cycle of a lithium-ion battery-operated pump under ambient temperatures. In an environmental-chamber kept at 35°C, the pump temperature increased by 4.4°C, which indicates that the pump temperature was above that of the recommended safety limit for insulin storage of 37°C. When designing new pumps, and when using currently available rechargeable pumps in warmer climates, the implications of these temperature increases should be taken into consideration. Future studies should also further examine insulin quality after charging. Keywords: insulin pumps, diabetes mellitus, safety, heating |
