This is a manual circular calculator for determining an appropriate insulin injection dosage to be taken with a meal. Preferably, the calculator has a pair of circular members which rotate around a single common center to allow calculation of the dosage. The front member includes a viewing panel showing an array of insulin injection dosage values that are printed on the rear circular member. The front member includes a series of measured blood glucose levels along a radius adjacent the viewing panel. The rear member typically has visible ingested carbohydrate values positioned along the outer perimeter of the member and, as noted above, a number of insulin injection dosage value arrays which become visible as one member is turned relative to the other. It is common that a physician would have a kit of these inventive devices, so that the appropriate one could be chosen depending on the insulin sensitivity, age, and size of the patient. In using the inventive calculator, a patient measures his or her blood glucose level and determines the weight of carbohydrates to be ingested at a particular meal. The carbohydrate ingestion is found on the outer perimeter of the back member of the device, the front member of the inventive device is turned so that an array of insulin values is visible, and the appropriate blood glucose level is read along the radius of the front circular member. The corresponding insulin injection dosage is seen in the window.
