Pumps

An insulin pump is a wearable insulin delivery device. Wearing a pump can ease the burden of diabetes care and give users more freedom with meal planning and physical activity. Pump use can also decrease the number of needle sticks a person gets per day by eliminating the need for multiple injections. With insulin pumps, meal and correction insulin can be delivered with ease by pushing buttons. Most pumps continuously release short- or rapid-acting insulin throughout the day and night to cover a user’s basal insulin requirements.

There are two types of insulin pumps: those connected to the body with tubing and tubeless devices worn directly on the body. Several insulin pumps communicate with a continuous glucose monitor (CGM). These pumps may use CGM glucose data to automatically adjust background (basal) insulin, deliver a correction (bolus) dose of insulin, or temporarily stop insulin delivery if glucose drops too low.
