BODYGUARDIAN CONTROL UNIT – BASE KIT Operator Manual
8
To ensure the safety of the patient and the operator, please follow all the warnings
and caution listed in this manual.
Connect to the equipment the proper specified power supply only. In order
to guarantee the electrical safety requirements, the recharge of internal battery
pack of equipment, must be performed by means the proper medical AC/DC
adapter only. The power supply is supplied by PREVENTICE with the
equipment. The allowed models are:
Trademark FRIWO, Model FW7662M/06
To recharge the equipment place it on the Charging Cradle according to the
appropriate orientation (only one is possible due to the mechanical constraints)
and only after this operation connect the Charging Cradle to the AC/DC Power
supply and this last to the mains.
After the recharging operation is complete disconnect the AC/DC Power
supply from the mains and only after this operation remove the equipment from
the Charging Cradle.
Take care when using the equipment at the same time with other
instruments. In the event the patient is connected to several instruments at the
same time, it is necessary to remember that the sum of the leakage currents
determined by each instrument may endanger his life.
Take care when using the equipment at the same time with other radio-
frequency instruments. In the event the equipment is used in a surgery room
at the same time with a radio knife (Radio-Frequency instrument = RF), it is
necessary to hold the radio knife point as far as possible from the electrodes, in
order to reduce as much as possible the risk of RF currents making on such
electrodes and the consequent burns. Therefore it is necessary to use electrodes
with a larger surface contacting the patient body, in order to limit the RF
current density to acceptable values. In case it is not possible to use the proper
electrodes, it is recommended to disconnect the patient from the equipment
before using radio-frequency instruments.
The equipment is not protected against the defibrillator discharges. Please
remember that the equipment is not protected against the defibrillator
discharges; for this reason, in the event it should be necessary to use the
defibrillator, it is necessary to disconnect the patient from the equipment in
order to avoid the patient being burned in the electrode contact areas and the
equipment undergoing sever and irreversible damages.
Avoid contact of patient and electrodes with conductive metal items. When
the equipment is connected to other instruments supplied by the mains, the
whole input circuit to which the patient is connected is electrically isolated
(floating isolation). It is necessary to avoid the patient and any conductive part
connected to the patient (electrodes, connectors, and transducers) coming into
contact with conductive parts (ground included). Please observe this precaution
to avoid compromising the equipment isolation level. This precaution must be
observed in order to avoid that accessible metal parts of the device get in touch
