Progress in practical endocrinology. The Glucosensor Unitec Ulm--a portable monitor for continuous blood glucose measurement.

The Glucosensor Unitec Ulm is the first portable glucose sensor for continuous glucose monitoring in blood. The Glucosensor weighs 850 g and has a size of 15 x 19 x 7 cm. Over a 24 hr period 15-25 ml of blood are withdrawn for continuous measurement, depending on the pumping velocity. Its storing capacity for data of blood glucose readings amounts to 32 KB. With the Glucosensor "long-term glucograms" under near-normal conditions can be registered. The glucograms enable the physician to recognize the different deteriorations of glucose met- abolism eg. periods of silent hypoglycemia during the night as well as postprandial hyperglycemia. The degree of glycemic control of diabetic patients can be analyzed and the effect of blood glucose lowering therapeutics can be realistically assessed.
