NeuroTrac™ PelviTone Operation Manual

What is STIM? Neuromuscular Stimulation has been used for many years to stimulate muscle and nerve fibres to treat a number of muscle and nerve related conditions. Over the last 30 years numerous clinical trials and papers have been written. The NeuroTrac™ PelviTone is one of a new breed of modern Neuromuscular stimulators which Verity Medical have developed with the Therapist and Patient in mind. Our principle aim is to design products that have high levels of functional use, are sensibly priced, compact and user friendly. The NeuroTrac™ PelviTone is a dual channel device combining several treatment programmes into one unit. Neuromuscular Stimulation is increasingly understood by Therapists and Doctors. There is a better understanding of the mechanisms which exist between nerves and muscles that make it possible to stimulate the neuromuscular system with precise electrical signals. The NeuroTrac™ PelviTone offers precision giving full control of Pulse Widths, Rates, Ramp up times, Work / Rest cycles as well as alternating or synchronous application if two channels are being applied. Customer Care We welcome constructive comments regarding our equipment particularly those that might help us to improve existing features, add new ones or develop new products for the future.

NeuroTrac™ PelviTone Operation Manual

Electrode Types & Tips Types Available: *

Normally vaginal or rectal probes are used with this device to achieve effective results. If self-Adhesive Hypoallergenic electrodes are used instead of the internal probes the results tend to be less effective. The typical life span of surface electrodes (if looked after) is 4/6 weeks. We recommend cleaning the skin before use. After use place the electrodes back onto the plasticfilm then enclose them back into the ziptag plastic pouch and store in a cool environment. Types available: VP.001 Internal Vaginal Probe, VP.002 Internal Vaginal Probe, VS.4040 40 x 40 mm (square), VS.5050 50 x 50 mm (square) (recommended for general use), VS.9050 90 x 50 mm (rectangular) VS.10050 100 x 50 mm (rectangular) (recommended for large muscles), VS.13050 130 x 50 mm (rectangular), VS.30 30 mm Diameter (round), VS.50 50 mm Diameter (round), VS.62 62 mm Diameter (round), VS.75 75mm Diameter (round).

A Few Good Tips [Self- Adhesive Electrodes] *

If you find the electrodes will not stick due to oily skin, cleanse the skin with soap and water, then rinse and dry the area around the electrode site. If this does not work, try cleansing the skin with a swab impregnated with alcohol.

*

Clip away hairy skin using scissors; don’t use a razor to remove the hairs!

The electrodes conductive material is water based. If it becomes saturated (e.g. from perspiration), it will loose its adhesive qualities. After use leave the electrodes face up overnight to dry out. At some point the electrodes will become dry. Moisten the adhesive surface with a few drops of water, and apply back onto the plastic film overnight. This procedure will give you a few more days of electrode life.

17

NeuroTrac™ PelviTone Operation Manual

Care & Maintenance Control Unit: * *

Wipe the surface once a week with a damp cloth or antiseptic wipe Do not use cleaning sprays or alcohol based cleaning solutions

Battery: * * * *

Check periodically for any discharge from the battery Remove battery completely from unit if not in use for any extended period of time (typically one week) Low battery indicator of 6.9 volts shown on LCD display. When flashing change battery for a new one Preferably use a heavy duty or PP3 alkaline battery

Lead Wires * * * *

The lead wires should be handled carefully and never stretched, as this can cause the stimulation to function below normal standards or not at all Examine lead wires before each treatment for loose connections or damage Avoid stretching and twisting the lead wires Store the lead wires carefully after each use

Self-Adhesive Electrodes * *

Check the short connectors have not become separated from the electrodes Replace electrodes onto plastic film after use. If they drop onto the floor debris will adhere to conductive gel rendering the electrodes ineffective

Vaginal / Rectal Probes *

Check the connectors have not become separated from the probe Caution: Static electricity may damage this product

NOTE:

Only Verity Medical Ltd or appointed distributors /importers are approved to undertake servicing.
