Appl. No.:

17/821653

Inventors:

- Acton MA, US
Ashutosh ZADE - San Diego CA, US
Yibin ZHENG - Hartland WI, US
Jason O'CONNOR - Acton MA, US

International Classification:

A61M 5/172
G16H 20/17
G16H 20/13
A61B 5/145

Abstract:

The insulin to carbohydrate ratio (ICR) and the correction factor for a user of a medicament delivery device may be automatically adjusted. The automatic adjustments may tailor the values to the user's actual insulin needs. Various factors may be examined to determine how to adjust the ICR and the correction factor. The identified factors are weighed with the processor to decide whether to increase or decrease the insulin to carbohydrate ratio or the correction factor. The insulin to carbohydrate ratio or the correction factor for the user are adjusted based on the weights of the identified factors. In addition or in the alternative, automatic adjustments of user-requested insulin boluses may be made to requested dosages and timing of deliveries of the insulin boluses. In some instances, the exemplary embodiments may deliver a percentage of the insulin bolus dosage initially and deliver the remaining percentage after a delay to reduce the risk of hypoglycemia for the user.

International Classification:

A61M 5/172
G16H 20/17

Abstract:

The exemplary embodiments attempt to identify impending hypoglycemia and/or hyperglycemia and take measures to prevent the hypoglycemia or hyperglycemia. Exemplary embodiments may provide a drug delivery system for delivering insulin and glucagon as needed by a user of the drug delivery system. The drug delivery system may deploy a control system that controls the automated delivery of insulin and glucagon to a patient by the drug delivery system. The control system seeks among other goals to avoid the user experiencing hypoglycemia or hyperglycemia. The control system may employ a clinical decision support algorithm as is described below to control delivery of insulin and glucagon to reduce the risk of hypoglycemia or hyperglycemia and to provide alerts to the user when needed. The control system assesses whether the drug delivery system can respond enough to avoid hypoglycemia or hyperglycemia and generates alerts when manual action is needed to avoid hypoglycemia or hyperglycemia.

International Classification:

A61M 5/172

Abstract:

Exemplary embodiments may provide an improved approach to automated insulin delivery by more accurately estimating the total daily insulin (TDI) of a user. As a result, less insulin is wasted by the delivery system, and the estimate of TDI more closely matches a user's actual daily insulin needs. Hence, the user need not refill the insulin reservoir excessively or need not fret unnecessarily about running out of insulin prematurely. The estimate relies on the history of actual automated insulin deliveries and thus reflects the actual insulin delivered to the user more accurately than conventional approaches.

Abstract:

In an automated insulin delivery device, fuzzy logic may be applied to the responding to the possibility of a user taking additional action that may affect the blood glucose concentration. Fuzzy sets may be defined for empirically derived different likelihoods of the user taking such additional action based on correlated factors. A membership function may be provided for each fuzzy set. The membership function may provide a probability of membership in the set based on a parameter. Each fuzzy set may have a response that is reflective of the likelihood of additional user action associated with the fuzzy set. The responses by the AID device to each of these cases may reflect the probability of each such case occurring as evidenced by empirical data.
