Infusion Pumps, Insulin, Ambulatory
Definition : Infusion pumps designed for use in the subcutaneous administration of insulin that are small enough to be worn or carried by patients. These pumps are frequently battery-powered devices that use a syringe-driven mechanism, an infusion rate controller, and an internal low-volume (e.g., 3 ml) reservoir containing the insulin solution. The insulin is delivered from the pump to a subcutaneous catheter typically inserted in the subcutaneous tissue of the abdomen. The pumps can be carried or worn, typically in a case attached to the patient's belt. Many pumps have memory capabilities and offer profile-based programming to account for daily patterns of insulin needs. Most pumps have an "automatic off" that terminates insulin infusion if a button on the pump is not pushed within a preprogrammed period of time. Ambulatory insulin infusion pumps infuse 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 mainly for patients having type I diabetes when it is not possible to obtain appropriate results using other insulin administration methods.
