Insulin Delivery Safety

A method for delivering an adjusted insulin bolus into a body of a patient comprising:

• selecting a first time corresponding to a duration of insulin action;
• selecting a second time corresponding to a lock out time duration;
• receiving input for a selection of a first time period beginning at a time point T0 minus the first time and ending at the time point T0 minus the second time;
• receiving input for a selection of one or more boluses delivered during the first time period;
• receiving input for a selection of a corresponding residual insulin value estimated at the time point T0 for each of the one or more boluses;
• computing a cumulative residual insulin value based on the corresponding residual insulin values;
• and
• computing an adjusted insulin bolus based on the cumulative residual insulin value.

A system for determining and delivering an adjusted insulin bolus into a body of a patient comprising:

• a fluid dispensing unit comprising one or more integrally connected housings containing a pump and a reservoir,
• a processor, the processor having a bolus recommendation application operating thereon configured for carrying out the following steps:
• receiving a first time corresponding to a duration of insulin action;
• receiving a second time corresponding to a lock out time duration;
• receiving a first time period beginning at a time point T0 minus the first time and ending at the time point T0 minus the second time;
• receiving a selection of a plurality of boluses delivered during the first time period;
• receiving a selection of a corresponding residual insulin value estimated at the time point T0 for each of the boluses;
• computing a cumulative residual insulin value based on the corresponding residual insulin values;
• and
• computing an adjusted insulin bolus based on the cumulative residual insulin value,
• wherein the pump is configured for dispensing the computed adjusted insulin bolus from the reservoir into a body of a user.
