Insulin pumps can be a wonderful alternative to injection therapy and are the closest thing we currently have to mimicking what the pancreas would do in someone who didn't have Type 1 diabetes. Pumps deliver insulin through an "insulin pump site" that is placed under the skin and typically changed every 2-3 days. Pumps can be programmed to deliver basal insulin (small drips of insulin released over 24 hours usually in 5 minute increments) as well as bolus insulin (bursts of insulin given before meals to cover carbohydrates). Bolus insulin can also be given along with a meal or separately to bring high blood sugars back into target.
