ULTRASOUND PROBE

摘要

According to the present invention a body (40) is inserted between an ultrasound crystal (30) and an output port (27) in a probe filled with a fluid, to centrally defocus generated ultrasound and create an output ultrasound field having limited propagation, especially for higher intensities, after passing the output port. The casing is divided into three portions (21, 22, 23), whereby a front conical portion (21) including the output port (27) and the centrally defocusing body (40) is easily replaceable, the fluid in the casing being refilled via a tube connection (12) to a fluid storage connected as a communicating vessel to the ultrasound device. Moreover, the output port of the device is provided with a thin membrane (10), preferably of replaceable latex rubber, which is attached by a special fixing means (11) to prevent the fluid in the casing from emerging, but at the same time enabling the effective transfer of generated ultrasound, whereby the fixing means preferably constitutes an O-ring gasket being placed in a circularly formed slot (25) on the conical portion.
