A reusable external infusion device infuses a fluid into an individual's body. The infusion device controls the rate that fluid flows from a reservoir inside a housing, through an external tube, and into the individual's body. Essentially, the infused fluid is insulin. However, many other fluids may be administered through infusion such as, HIV drugs, drugs to treat pulmonary hypertension, iron chelation drugs, pain medications, anti-cancer treatments, vitamins, hormones, and others.
