Diabetes devices are used in managing and treating diabetes and the market is filled with a vast variety of these devices. Diabetes devices can be broadly classified into two segments - glucose monitoring devices and insulin delivery devices. Insulin pumps are small, computerized devices that mimic the way the human pancreas works by delivering small doses of short acting insulin continuously. The device is also used to deliver variable amounts of insulin when a meal is eaten. The basal insulin rates are usually set up in pump with doctor, and one can have one or multiple basal settings programmed in the pump.
