[Automated maintenance of a central file of blood donors]

Data processing of medical information gathered by the physician working in the mobile unit, has been optimized and automatized. Thanks to the simultaneous use of an optical mark reader and a lightpen it is possible to achieve a quick data entry without a manual keyboard as soon as the mobile blood units bring back the samples. The donnors' medical cards which accompany each blood sample are transmitted from the mobile unit to the laboratory for better test accuracy. This simple system, operating since October 1984, has proven its reliability and efficiency.
