Abstract
313,512. Siemens - Reiniger - Veifa Ges. fiir Medizinische Technik. June 13, 1928, [Convention date]. Electric appliances. - In electromedical apparatus having a metal casing and leads extending beyond the casing to a patient, at least one of the leads has a connection with the casing, which permits the passage of low frequency currents. In a metal casing f, which may be earthed at f<1>, is housed a high-frequency transformer a, b with the secondary terminals i connected to electrodes h. The highfrequency primary is supplied from a source of alternating current from a low-frequency hightension transformer d. In order to avoid shock in case of a breakdown of the high-tension transformer, at least one of the electrodes h is connected to the casing k directly, through a highfrequency choke m, or through a protective sparkgap or the like.
