Method and device for improving glycemic control
View Patent ↗Systems, devices and methods are presented in the subject disclosure for recommending an insulin dose adapted for use with an insulin delivery device. In some embodiments, the method may include receiving blood glucose (BG) data, determining one or more insulin sensitivity (IS) values associated with the BG data, and determining an insulin dose based on the determined one or more IS values. A system for carrying out such a method is also presented.
1. A method for recommending an insulin dose adapted for use with an insulin delivery device, the method comprising:
providing the insulin delivery device comprising:
a housing containing therein a pump for dispensing the insulin bolus dose into a body of a user;
input means for receiving blood glucose (BG) data;
a remote control containing therein a processor having a dose advisor application thereon configured to determine insulin sensitivity (IS) values based on corresponding BG ranges having the following IS values: BG<50→IS=170mg/dL/U, 50<=BG<70→IS=130mg/dL/U, 70<=BG<=150→IS=100mg/dL/U, 150<=BG<=200→IS=80mg/dL/U, 200<BG<=250→IS=60mg/dL/U, 250<BG<=300→IS=50mg/dL/U, and 300<BG→IS=40mg/dL/U;
a memory for storing the BG data and the IS values; and
a display for presenting output associated with the IS values which comprises an IS value used for an insulin bolus dose determination and a determined insulin bolus dose;
receiving the BG data comprising a BG level;
determining one of the IS values associated with the BG data via the dose advisor application;
receiving input from the user as to an amount of carbohydrates (Carbs) the user is about to consume;
receiving, via the dose advisor application, a carbohydrate to insulin ratio (CIR), a target blood glucose level (TBG), and a residual insulin level (RI);
calculating the determined insulin bolus dose using the equation:
(Carbs/CIR)+(BG−TBG)/IS−RI; and
displaying the IS value used for the insulin bolus dose determination and the determined insulin bolus dose as the recommended insulin dose.
2. The method of claim 1 , wherein the BG data further comprises a BG trend.
3. The method of claim 1 , wherein receiving BG data includes at least one of: receiving an input from a user, and receiving a signal from a glucose monitor.
4. The method of claim 1 , further comprising visually presenting the one or more IS values as a function of BG data.
5. The method of claim 4 , wherein visually presenting includes presenting a graph or a table showing matching between the IS values and the BG data.
6. The method of claim 1 , further comprising retrieving from the memory the one or more IS values associated with BG data.
