Using heart rate to identify daily events and automatically adjust the basal rate on an insulin pump

An insulin pump allows Type 1 diabetics to fine tune their blood glucose control by temporarily adjusting their basal (background) insulin for fluctuations in blood glucose level caused by different daily activities such as exercise. Anaerobic exercise typically causes an increase in a person's blood glucose whereas aerobic exercise typically causes a reduction in a person's blood glucose level. Other non-sedentary activities such as house work also can cause blood glucose to drop. Typically post exercise there is a drop in blood glucose levels as well.

The current method for managing this with an insulin pump is a manual process and requires the user to remember to do so. Forgetting to do so may result in hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar) depending on the activity.

Current solutions to this problem are as follows: - Pumps currently allow users to set a temporary basal rate of a percentage of the

normal basal rate for an amount of time. This has to be activated manually and there is no prompt for the user to do so and as a result can be forgotten.

- Pumps also have preset temporary basal rates that are basically pre-programmed basal rates for a given type of activity. For example, an anaerobic profile could be set up that increases the basal rate to 120%. Again this has to be activated manually and there is no user prompt so can easily be forgotten. The system would use a wearable heart rate monitor synced with the insulin pump to detect daily activities such as aerobic/anaerobic exercise or other non-sedentary activities. Then automatically change the basal rate of the insulin pump to a preset temporary basal rate. The monitor w...
