Ancillary Accessories

To facilitate the acquisition of electrophysiological information using this system, there are ancillary accessories that must be used. These
accessories include surface electrodes and needle electrodes that are not included with the system. To ensure proper use of the system;
descriptions, recommendations and or specifications are provided for these ancillary accessories that are deemed compatible with the
Keypoint G4 system.
It is recommended that the surface electrodes selected are those that have been cleared or approved for nerve conduction and or evoked
potential studies. Either disposable or reusable surface electrodes may be used. The size of the electrode should be appropriately selected for
the test being conducted. Reusable surface electrodes are made of metal and are typically fabricated from platinum, gold or silver. Metallic
reusable electrodes must be cleaned and or conditioned for reuse according to instructions provided by the manufacturer of those electrodes.
All surface electrodes used should have a protective pin connector that complies with DIN 42 802 standard. This nonproprietary pin connector is
an industry standard for EMG systems.
Disposable and reusable needle electrodes may be used. Needle electrodes are fabricated from a variety of materials. It is recommended that
the needle electrodes selected are those that have been cleared or approved for electromyography applications. Use a length and gauge
appropriate for the test being conducted. The connector is a circular 5 pin DIN connector. This nonproprietary pin connector is an industry
standard for EMG systems. The pin configuration for this connector is as follows: pin 1 is active, pin 2 is reference, pin 3 and pin 4 are shield
drivers and 5 is patient ground.
