Abstract
A device for shock wave production to treat a patient's body comprises a base with a condenser as power supply, an applicator having a pad, at least one piezo-element configured to generate a shock wave in response to a pulse of electric current having a pulse width, an acoustic lens configured to focus the shock wave, and a coil configured to increase the pulse width of the pulse of electric current.
Claims20
A device for shock wave production to treat urological problems of a patient's body, comprising:
- a condenser and a switch configured to discharge a pulse of electric current;
- and
- an applicator configured to be coupled to the condenser and the switch and configured to provide a shock wave pulse to the patient's body, the applicator comprising:
- an applicator cell comprising a cavity;
- a single piezo-element attached to the applicator cell at a bottom of the cavity configured to generate the shock wave pulse in response to the pulse of electric current;
- a dielectric material positioned in the cavity, fixing the single piezo-element in the cavity;
- and
- an acoustic lens attached to the applicator cell below the single piezo-element configured to focus the shock wave pulse into the patient's body to provide pressure to the patient's body to treat the urological problems of the patient's body;
- wherein the single piezo-element has a volume in a range of 1.5 cm3 to 600 cm3.
