From the Guidelines

Insulin pumps are a type of medical device that typically uses an external battery. These devices are designed to mimic physiological insulin delivery over 24 hours with basal and bolus insulin infusions of rapid-acting insulin analogues 1. Many medical devices that require portability or continuous operation outside of healthcare settings typically use external batteries, including portable oxygen concentrators, continuous glucose monitors, hearing aids, external defibrillators, TENS units for pain management, and various home monitoring devices like blood pressure monitors.

  • External batteries provide several advantages for these devices, including the ability to replace or recharge batteries without interrupting the device's function, which is crucial for life-supporting equipment.
  • They also allow for longer operation times through battery swapping and make the devices more lightweight and portable.
  • For critical medical equipment like portable ventilators or infusion pumps, external batteries serve as both the primary power source when patients are mobile and as backup power during electrical outages, ensuring continuous operation for patients who depend on these devices for survival or maintaining their health. According to a recent study published in 2023, automated insulin delivery systems, which include insulin pumps, require careful consideration of battery life and charging capabilities, especially during travel or in areas with limited access to power sources 1. Another study published in 2022 highlights the importance of understanding the data-sharing capabilities of automated insulin delivery systems, which may include the use of external batteries to power the device 1.

From the Research

Medical Devices Using External Batteries

  • Insulin pumps are a type of medical device that typically uses an external battery 2, 3, 4.
  • These devices are used for continuous subcutaneous insulin infusion (CSII) and are commonly used by people with type 1 diabetes 2, 3, 4.
  • External batteries are used to power the insulin pump, which delivers insulin to the user through a small catheter 3.
  • The use of external batteries allows for greater flexibility and convenience in managing diabetes, as users can easily replace or recharge the batteries as needed 4.

Key Features of Insulin Pumps with External Batteries

  • Insulin pumps with external batteries often have safety features, such as alarms and alerts, to notify users of potential issues with the device 2.
  • They also have technical features, such as adjustable basal rates and bolus doses, to allow users to customize their insulin delivery 3, 4.
  • Some insulin pumps with external batteries may also have integrated continuous glucose monitoring systems, which allow users to track their blood glucose levels in real-time 4.

Benefits of Insulin Pumps with External Batteries

  • Insulin pumps with external batteries can improve glycemic control and reduce the risk of hypoglycemia and diabetes-related complications 4.
  • They can also improve quality of life for users, by providing greater flexibility and convenience in managing their diabetes 4.
  • The use of external batteries can also make it easier for users to travel and engage in physical activity, without worrying about running out of power 3.
