An electro-acupuncture device for controlling nausea. The device includes
a base unit which is includes a wrist-watch like housing, circuitry for
generating electro-acupuncture stimulus disposed within the housing, and
a strap for securing the housing to the wrist. The base unit has a
standardized construction. The device also includes a releasably
attachable electrode assembly. The electrode assembly attaches to the
base unit of the device. The electrode assembly includes a pair of
electrodes and connectors for connecting the electrodes to the circuitry
of the base unit. The output of the device is dependent upon the
circuitry of the electrode assembly. Thus various electrode assemblies
can be made. The circuitry of the base unit modifies the output of the
device depending upon which electrode assembly is attached to the base
unit.
