Abstract
Methods of establishing an insulin delivery rate in a pump and an insulin pump are disclosed. A method includes selecting a set of alerts from one or more sets of alerts. The method also includes initiating a test process based on the set of alerts. The method further includes, upon activation of each alert in the selected set of alerts, prompting a user to input a blood glucose level.
Core Innovation
The disclosed invention relates to an ambulatory infusion pump system in which insulin meal bolus delivery is produced from user-selected food entries and carbohydrate values. A processor presents a bolus calculation feature on a user interface to receive input from a user to calculate a meal bolus delivery of insulin, selects one or more food entries from a food database, and updates the bolus calculation feature to include the carbohydrate value for each selected entry.
The processor calculates an insulin meal bolus based on a total carbohydrate value of the selected one or more food entries defining the meal and causes the pump mechanism to deliver the calculated insulin meal bolus to the user. In a related embodiment, a handheld computing device implements the bolus calculation feature and transmits a command to an ambulatory infusion pump to deliver the calculated insulin meal bolus for the meal to a user.
The invention further refines the meal-bolus calculation with additional parameters beyond total carbohydrate value, including a carbohydrate ratio and an amount of insulin on board. The disclosed operation also includes a modification of the calculated meal bolus based at least in part on the user’s glucose level, and alternative embodiments include different pathways for food database access and the option for selecting a food entry representing a single food item.
Claims Coverage
The partial content includes two independent claims. Across these claims, the inventive features focus on meal bolus calculation from user-selected food entries and carbohydrate values, with delivery by direct pump control or by command transmission from a handheld computing device.
Food database-driven meal bolus calculation and pump delivery
A processor presents a bolus calculation feature on the pump’s user interface to receive user input, receives selection of one or more food entries from a food database where each entry is associated with a carbohydrate value, updates the bolus calculation feature to include the carbohydrate value for each selected entry, calculates an insulin meal bolus based on a total carbohydrate value of the selected entries defining the meal, and causes the pump mechanism to deliver the calculated insulin meal bolus for the meal to the user.
Handheld bolus calculation and command transmission to the pump
A handheld computing device presents on its user interface a bolus calculation feature configured to receive input from a user to calculate a meal bolus delivery of insulin, receives through the bolus calculation feature a selection of one or more food entries from a food database where each selected entry is associated with a carbohydrate value, updates the bolus calculation feature to include the carbohydrate value for each selected entry, calculates with the bolus calculation feature an insulin meal bolus based on a total carbohydrate value of the selected entries defining the meal, and transmits a command from the handheld computing device to the ambulatory infusion pump to deliver the calculated insulin meal bolus for the meal to a user.
Both independent claims cover meal bolus calculation from user-selected food entries and carbohydrate values stored in a food database, with delivery implemented either by directly causing the pump mechanism to deliver the calculated insulin meal bolus or by transmitting a command from a handheld computing device to the pump. Dependent refinements in the provided content additionally incorporate carbohydrate ratio, insulin on board, and modification based at least in part on the user’s glucose level.
