A portable, pre-programmable insulin infusion system in diabetes mellitus

A miniaturized portable pump has been developed in order to study the effects of pre-programmed insulin infusion patterns on the blood glucose levels in juvenile-onset, insulin-requiring diabetics. Six diabetics undergoing 7 insulin infusion periods of up to 4 days were studied. The mean blood glucose was 7.0 +/- 2.3 (SD) mmol/l and the mean amplitude of glycemic excursions was 5.0 +/- 1.4 mmol/l. Success in achieving normoglycemia will depend on choosing the correct dose of insulin for infusion.
