A Guideline to Insulin Pump Therapy For Type-1 Diabetes 

An insulin pump is a machine that helps people with diabetes by giving them insulin. The pump has a battery, an infusion pump, and an internal insulin reservoir. The pump is linked by tubing to a small, thin tube (cannula) that goes under the skin. usually in the abdomen. It helps in providing a small amount of insulin continuously throughout the day and night. The pump is worn discreetly and the cannula must be changed every 2-3 days to avoid skin irritation or infection. The pump is programmed to give a person a small, continuous amount of insulin (called the basal rate) and can be set to give more insulin at mealtimes (called a bolus).
