Insulin pumps have been around for the past decade, aiding type 1 diabetics in controlling their blood glucose levels. Previous pumps have required manual input for it to administer insulin. Recent developments of the closed loop system mean you are only required to add of discrete amount of insulin within a specific time that corresponds to the amount of carbs you are about to consume. The closed loop system then continues to monitor your blood sugar level throughout the day, automatically administering slightly more insulin as levels rise, and reducing the amount when levels lower. There are many ways to wear the pump. You can attach it to your belt, protect it in your pocket, or even clip it under your clothing.?https://diabetesnsw.com.au/helpful-resources/
