<s>[INST] How does an insulin pump work? [/INST] Insulin pumps are small, wearable devices individually programmed to deliver insulin into the body at numerous intervals throughout the day and night. They are used in place of multiple daily injections (MDI) of insulin.

Insulin pumps release a low, steady flow of insulin 24 hours a day (basal insulin), as well as extra doses of insulin (boluses) to accommodate rises in blood sugar as needed (e.g., when one eats).
