Acoustic therapy device, e.g. for dry-couple lithotripsy

摘要

The acoustic therapy device includes a source (1) of focused acoustic waves. A number of coupling devices are selectively coupled to the source. Acoustic waves are applied to a patient via a coupling surface. Each coupling device has a volume such that acoustic waves are conducted freely from a radiation surface to the coupling surfaces. At least one of the coupling devices includes an acoustic broadening medium. At least one coupling device is elastically bendable. A volume equaliser (14) is provided for the acoustic broadening medium.
