The insulin pump is a medical device used for the administration of insulin in the treatment ofdiabetes mellitus, also known as continuous subcutaneous insulin infusion therapy. The device configuration may vary depending on design. A traditional pump includes:
- the pump (including controls, processing module, and batteries)
- a disposable reservoir for insulin (inside the pump)
- a disposable infusion set, including a cannula for subcutaneous insertion (under the skin) and a tubing system to interface the insulin reservoir to the cannula.
Other configurations are possible. For instance, more recent models may include disposable or semi-disposable designs for the pumping mechanism and may eliminate tubing from the infusion set.
An insulin pump is an alternative to multiple daily injections of insulin by insulin syringes or aninsulin pen and allows for intensive insulin therapy when used in conjunction with blood glucose monitoring and carb counting.
