Medisafe Fit Smile is a blood glucose meter which focuses on patient-friendly design, thus encouraging patients to continue therapy. Even newly diagnosed diabetics need to improve their diets and exercise by identifying good and bad blood glucose levels (BGL) on their own. This device expresses BGL ranges using colors and emoticons, allowing even beginners to properly ascertain their BGL. Colors assigned to BGL ranges can be easily changed by the doctors; this enables customized monitoring that’s crucial in encouraging adherence to treatment.
