A recently granted patent (Publication Number: US11911595B2) outlines a system for closed-loop diabetes therapy that includes a pump mechanism for insulin delivery, a communications device receiving glucose levels from a continuous glucose monitor, and at least one processor. The processor is configured to calculate and deliver insulin doses based on a closed-loop insulin delivery algorithm, adjusting insulin levels to maintain the user's glucose and insulin on board targets. The system also includes a pre-meal scale that modifies the algorithm in response to an indication of an upcoming meal, ensuring insulin doses are tailored to the user's needs before and after eating.

Furthermore, the patent details a method for closed-loop diabetes therapy that involves receiving glucose levels from a continuous glucose monitor, calculating insulin doses based on the closed-loop algorithm, and delivering the doses with a pump mechanism. The method includes activating a pre-meal scale in response to an indication of a meal, adjusting the insulin on board target to accommodate the upcoming food intake. This innovative approach aims to provide more personalized and effective diabetes management by dynamically adapting insulin delivery based on real-time glucose levels and anticipated meals, potentially improving overall glycemic control for individuals with diabetes.
