Claim 10:
11. A method of closed loop diabetes therapy, comprising:
receiving glucose levels of a user from a continuous glucose monitor;
calculating insulin doses to the user based on a closed loop insulin delivery algorithm, the closed loop insulin delivery algorithm including an outer glucose loop that compares glucose levels from the continuous glucose monitor to a glucose target to determine an insulin on board target for the user and an inner insulin on board loop that compares an estimated insulin on board for the user to the insulin on board target to determine an insulin on board error used to calculate insulin doses configured to maintain the insulin on board of the user at the insulin on board target and the glucose levels of the user at the glucose level target;
delivering the calculated insulin doses to the user with a pump mechanism;
receiving an indication that the user will be eating a meal;
activating a pre-meal scale for the closed loop insulin delivery algorithm in response to the indication that the user will be eating the meal, the pre-meal scale modifying the inner insulin on board loop of the closed loop delivery algorithm that calculates insulin doses to maintain the insulin on board of the user at the insulin on board target; and
calculating and delivering insulin doses to the user based on glucose levels from the continuous glucose monitor using the pre-meal scale of the closed loop insulin delivery algorithm following the indication that the user will be eating the meal.
