Radarmed 12 S 200 heat therapy unit, 1959

The history of Bosch medical technology stretches back to 1949, when the first “Omniton” hearing aid was launched on the market. A year later, the company started developing electric medical apparatus for therapeutic applications.


These included microwave heat therapy units, which warmed selected parts of the body under the skin for use in orthopedic and ENT treatments, for example. The Radarmed was a popular therapeutic device among doctors in West and Middle Europe for decades, especially for ear, nose and throat specialist. The warmth also helped healing inflammatory deseases.
