Abstract
A sound wave treatment device for medical treatment using compression waves, in particular for lithotripsy, includes a sound wave generator, a plurality of piezo elements that are coupled to the sound wave generator, and, an electrical high voltage unit that is set up for supplying the piezo elements with high electrical voltage. The high voltage unit has a blocking converter unit having a transformer, wherein the transformer has a primary coil, a high voltage coil, and spacers, wherein the high voltage coil has a plurality of high voltage windings that are embedded in an insulating mass and are positioned using the spacers such that adjacent high voltage windings are at a defined distance (a) from one another due to the spacers.
