An Audio Urine-glucose Analyzer for Blind Diabetics

At the instigation of one of the authors (J. M.)–a young man whose blindness is due to diabetic retinopathy–a urine-glucose analyzer was designed and constructed. Its purpose and function enable him to test his urine himself (free of dependence on others for this service) and, thereby, he can then determine and administer his doses of insulin. He and other young blind diabetics may value the degree of freedom from dependence on others tha the analyzer provides and feel it helps them to be able to work and care for themselves. A description of the instrument, instructions for its use, and a summary of about 20 months' experience with it are submitted.
