4. SAFETY CAUTIONS AND OTHER WARNINGS
The use of the multichannel EMG-USB2 amplifier is
conditions:
While other monitoring devices are in use with the patient.
While electro surgery equipment, short waves or microwaves therapy devices are used.
By mentally impaired people.
Whenever the equipment is damaged.
In proximity of inflammable substances (especially inflammable liquids and gases) or in
environments with high concentration of oxygen.
On patients carrying life-supporting equipment that might be adversely affected by
electromagnetic interferences, such as pacemakers, etc.
The following cautions should be observed:
The detection of iEMG signals must be supervised by trained medical staff.
Only use electrodes supplied by the manufacturer: EMG-USB2 is guaranteed to achieve tested
performance only if used with electrodes supplied by the manufacturer.
Contact the manufacturer immediately if extraneous materials permeate into the device
(liquids, powders, etc.). In case of hard shocks suffered by the EMG-USB2 (like a drop to the
floor, etc.), verify that no crack or any other kind of damage of the box resulted from the
shock. In case of doubt, please contact the manufacturer.
The EMG-USB2 is subject to electromagnetic interference that is not dangerous for the patient
(such as electrostatic or electromagnetic interference generated by electrical motors and other
sources). This interference may affect the measurements of the physiological variables derived
from the EMG or EEG signals. These measurements are not meant to be used for diagnostic
purposes, and thus these signal alterations cannot be dangerous for the patient, please always
take into account the presence of noise in your signal processing tasks and evaluations.
Before making any measurement, it is mandatory to check the quality of the grounding of the
power line to which the EMG-USB2 is connected.
grounding connections not compliant with safety standards represents a high risk
for the patient and the operator.
The connection between EMG-USB2 and other electrical devices (e.g. a PC) must be done in
compliance with the European standard EN 60601-1-1 on medical devices.
