MAN ECG preamplifier
22.3

Safety Rules to be followed

•
The ECG preamplifier is an integral part of the ultrasound scanner unit. The unit may only be
operated in places that go conform with the rules for medically used locations.
•
The power cable of the ultrasound scanner unit must not be connected to a damaged socket. The
socket must be equipped with a grounded conductor. If necessary a potential equilibrium must be
connected.
•
Only the patient cable provided by GE Medical Systems Kretztechnik (KENDALL medizinische
Erzeugnisse, Code 8/P93/07-01, Ref 3227.0701.00) may be used. Consequently, only push-button
electrodes may be used.
•
Take care that neither bare parts of one of the electrodes nor the patient can get in contact with
conductive parts (e.g., metal parts of the examination bed, trolley, or similar).
•
This device must not be used for an intra-operative application on the heart.
•
If the use of a HF surgical unit with simultaneous connected ECG electrodes becomes necessary, a
maximum distance of ECG electrodes from the surgical field and a correct position and contact of
the neutral electrode of the HF surgical unit must be observed (avoidance of burning risk).
•
Note that stimulation current devices can influence the ECG signal.
•
If several instruments are simultaneously used on the patient, all these instruments must be
connected to an appropriate potential equilibrium (avoidance of lead currents).
•
If the use of a defibrillator becomes necessary, there must be no ECG adhesive electrodes and no
conductive paste between the contact positions of the defibrillator plates (avoidance of current
bridges; the signal input of the ECG preamplifier is defibrillator-safe).
Note: Follow the User Manual of the defibrillator.
Do not touch the patient during the defibrillation.

Care and Maintenance, Repairs

•
Electrodes and the cables should be handled with the usual care.
Refer to manufacturer's instructions in concerns of cleaning and maintenance.
•
Refer to manufacturer's instructions concerning sterilization.
•
The ECG preamplifier does not require special maintenance but should be handled with care.
•
Do not perform any changes or repairs on the ECG preamplifier, the connecting cables or the
patient cable. A damaged patient cable must be replaced.
• Necessary repairs must be performed by authorized service personnel only!
