Diabetes is on the rise worldwide. Some 10 million people are diagnosed with the disease every year.
That unfortunate statistic has led to increased demand for insulin pens. These medical devices are used by diabetics to inject insulin. The device is consists of an insulin cartridge, a dial to measure the dose, and disposable pen needles to deliver the dose. Insulin pens offer several advantages over the traditional vial-and-syringe method of insulin delivery, including improved patient satisfaction and adherence, greater ease of use, superior accuracy for delivering small doses of insulin, greater social acceptability, and less reported injection pain.
