How common is an insulin pump?
Hundreds of thousands of people with diabetes worldwide are using an insulin pump. Although insulin pumps were first used by people with type 1 diabetes, people with type 2 diabetes sometime use them as well. Many pediatric patients successfully use insulin pumps. Insulin pumps allow for tight blood sugar control and lifestyle flexibility while minimizing the effects of low blood sugar (hypoglycemia). At present, the pump is the closest device on the market to an artificial pancreas. Newer models of the pump have been developed that do not require a tubing, in fact - the insulin delivery device is placed directly on the skin and any adjustments needed for insulin delivery are made through a PDA like device that must be kept within a 6 foot range of the insulin delivery device, and can be worn in a pocket, kept in a purse, or on a tabletop when working.
Probably the most exciting innovation in pump technology is the ability to use the pump in tandem with newer glucose sensing technology. Glucose sensors have improved dramatically in the last few years, and are an option for patients to gain further insight into their patterns of glucose response to tailor a more individual treatment regimen. Implantable glucose sensors communicate wirelessly with a pager-sized device that has a screen to give real-time glucose readings. The sensors can be programmed to produce a "beep" if blood sugars are in a range that is selected as too high or too low. Some can provide a warning beep if the drop in blood sugar is occurring too quickly.
Further, studies are underway to examine systems that combine insulin delivery and real-time glucose monitoring. The ultimate goal of this technology is to "close the loop" by continuously sensing what the body needs, and then responding by providing the appropriate dose of insulin. Preliminary studies have already shown success with these "closed loop" systems.
