Some health care providers prefer the insulin pump because its slow release of insulin mimics how a normally working pancreas would release insulin. Studies vary on whether the pump provides better blood glucose control than multiple daily injections. Another advantage of the insulin pump is that it frees you from having to measure insulin into a syringe.
An insulin pump is a medical device continuously delivering insulin under the skin through a catheter. Its usually connects somewhere in the waist area. Theres a new generation of insulin pumps, called a patch pump. Currently patch pumps are only available from OmniPod. Patch pumps adhere directly to the skin with no catheter tubing showing. It then infuses insulin directly under the skin.
Either pump delivers insulin at an hourly rate. For instance, the rate might be 1.1 units an hour. However, the pump delivers different rates at different times of day depending on the patients insulin infusion (or basal) rates that are programmed into the pump.
