First Claim
Patent Images
1. A stack of components for use in a microcurrent therapy device (MCTD) comprising:
- a coin battery with a first terminal and a second terminal;
a circuit board with components for an electric circuit used in the MCTD;
a battery pad adjacent to the bottom of the circuit board and electrically connected to a portion of the electric circuit;
the battery pad sized to contact the first terminal without touching the second terminal of the coin battery that encircles the first terminal;
a battery clip adapted;
1) to provide an electrical connection from the second terminal of the coin battery to the top face of the circuit board; and
2) to maintain a compressive force on a subassembly of the MCTD comprising the circuit board, battery pad, coin battery, and battery clip.

Abstract
A microcurrent therapy device (MCTD) for use in applying a DC current of less than one milliampere between two conductive pads through the tissue of a therapy recipient has an electronic stack that can be placed in electrical connection with the user'"'"'s skin and thus in electrical connection with the other skin contact plate, a profile minimizing system using an off the shelf “coin ” battery within the electronic stack, and a battery clip used in conjunction with a coin battery and the circuit board of the MCTD.
