Abstract

An electro-acupuncture device (1) for controlling nausea. The device includes a base unit (6) including a wrist-watch like housing, circuitry for generating electro-acupuncture stimulus disposed within the housing and a strap (2) for securing the housing to the wrist. The base unit has a standardized construction. The device also includes a releasably attachable electrode assembly (7). The electrode assembly attaches to the base unit and includes (4) and connectors (12) 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. The circuitry of the base unit modifies the output of the device depending upon which electrode assembly is attached to the base unit.
