ABSTRACT:
In a handheld piezoelectric acupuncture stimulator with a pen-like, substantially electrically insulating exterior casing (1), at one end of which an actuator button (5) is mounted, while the other end is provided with a contact pin (9), which is connected with a first electrode of a piezoelectric converter, which by means of a spring-loaded impact hammer actuated by the actuator button (5) may be mechanically operated for generation of a high voltage electric pain relieving pulse with a low energy content, the piezoelectric converter with associated electrodes and said impact hammer with associated spring system are mounted in a common electrically insulating interior casing (8) designed for form-fit mounting in the exterior casing (1), whereby the electric connection between the second electrode of the piezoelectric converter and a contact ring (7) on the exterior casing comprises a leaf spring contact (10), which projects through the interior casing (8) and extends between said interior casing and the exterior casing (1).
