Nash Contra logoscope in case, an aid to differential diagnosis in 'slide-rule' form, developed by Dr Firmin Nash, manufactured by Medical Data Systems, Nottingham, England, 1974-1975

Dr Firmin Nash designed the logoscope in the age just before the personal computer. It aided differential diagnosis in ‘slide-rule’ form. It attempted to be a diagnostic tool providing a broad, but accurate, list of possibilities for GPs to consider alongside their own diagnostic skills. Each plastic strip has a different illness, for instance ‘yellow fever’ or ‘influenza’, and is marked with a series of black lines. The GP collects the conditions which he suspects might be causing the problem and places them on the plastic slide-rule. The GP then uses the magnifier to see where the lines correspond with the observed symptoms which are marked along the side.

Personal computers became widely available by the time the logoscope reached final design, although they sold well in Japan. This logoscope was made by Medical Data Systems. It covers six areas of expertise: the alimentary system, respiratory disease, cardiovascular, endocrine, bone and joint, and the nervous system. Devices such as this that ‘mechanise’ diagnosis have not usually caught on. They were soon superseded by computers.
