Infusion Pumps, Insulin, Implantable
Definition : Infusion pumps designed to deliver insulin that are intended for implantation. These pumps are frequently battery powered devices that use a syringe-driven mechanism, an infusion rate controller, and an internal small-volume (e.g., 3 ml) reservoir containing the insulin solution; the insulin is delivered from the implanted pump to a subcutaneous catheter with a needle at the distal end that is typically inserted in the subcutaneous tissue or the peritoneal cavity. Implantable insulin pumps are usually programmable using an external telemetric programing device according to the individual needs of basal and bolus insulin rates. Many units offer profile-based programming to account for daily patterns of insulin needs. The insulin is infused in micro volume pulses that mimic the function of a normal pancreas; the pump must be also able to deliver mealtime or supplementary bolus doses of insulin when necessary. They are intended for patients having type I diabetes when it is not possible to obtain appropriate results using other conventional insulin administration methods.
