2.3 Electrical Safety

This equipment has been verified as a Class I device with Type BF applied parts.

2.3.1 Prevention of Electric Shock

In a hospital, dangerous currents are due to the potential differences between

connected equipment and touchable conducting parts found in medical rooms. The solution to the problem is consistent equipotential bonding. Medical equipmen is connected with connecting leads made up of angled sockets to the equipotential bonding network in medical rooms.

[Figure 2-4] Equipotential bonding

Additional equipment connected to medical electrical equipment must compl

with the respective IEC or ISO standards (e.g. IEC 60950 for data processing equipment). Furthermore all configurations shall comply with the requirements for medical electrical systems (see IEC 60601-1-1 or clause 16 of the 3 Ed. of IEC 60601-1, respectively). Anybody connecting additional equipment to medical electrical equipment configures a medical system and is therefore responsible that the system complies with the requirements for medical electrical systems. Attention is drawn to the fact that local laws take priority over the above-mentioned requirements. If in doubt, consult your local representative o the technical service department.

Chapter 2. Safety

WARNING

CAUTION

y Electric shock may exist result if this system, including and all of its

externally mounted recording and monitoring devices, is not properly grounded.

y Do not remove the covers on the system; hazardous voltages are present

inside. Cabinet panels must be in place while the system is in use. All internal adjustments and replacements must be made by a qualified MEDISON Customer Service Department.

y Check the face, housing, and cable before use. Do not use, if the face is

cracked, chipped, or torn, the housing is damaged, or if the cable is abraded.

y Always disconnect the system from the wall outlet prior to cleaning the

system.

y All patient contact devices, such as probes and ECG leads, must be

removed from the patient prior to application of a high voltage defibrillation pulse.

y The use of flammable anesthetic gas or oxidizing gases (N20) should be

avoided.

y The system has been designed for 100-120VAC and 200-240VAC; you

should select the input voltage of monitor, printer and VCR. Prior to connecting an OEM power cord, verify that the voltage indicated on the power cord matches the voltage rating of the OEM device.

y An isolation transformer protects the system from power surges. The

isolation transformer continues to operate when the system is in standby.

y Do not immerse the cable in liquids. Cables are not waterproof. y The operator does not contact the parts (SIP/SOP) and the patient

simultaneously

2.3.2 ECG-Related Information

WARNING

y This device is not intended to provide a primary ECG monitoring function,

and therefore does not have means of indicating an inoperative electrocardiograph.

y Do not use ECG electrodes of HF surgical equipment. Any malfunctions in

the HF surgical equipment may result in burns to the patient.

y Do not use ECG electrodes during cardiac pacemaker procedures or other

electrical stimulators.

y Do not use ECG leads and electrodes in an operating room.

Chapter 2. Safety

2.3.3

CAUTION

ESD

Electrostatic discharge (ESD), commonly referred to as a static shock, is a naturall occurring phenomenon. ESD is most prevalent during conditions of low humidity, which can be caused by heating or air conditioning. During low humidit conditions, electrical charges naturally build up on individuals, creating static electricity. An ESD occurs when an individual with an electrical energy build-up comes in contact with conductive objects such as metal doorknobs, file cabinets, computer equipment, and even other individuals. The static shock or ESD is discharge of the electrical energy build-up from a charged individual to a lesser o non-charged individual or object. The ESD caution symbol is on the probe connector and the rear panel.

[Figure 2-5] ESD symbol

y The level of electrical energy discharged from a system user or

patient to an ultrasound system can be significant enough to cause damage to the system or probes.

2.3.4 EMI Although this system has been manufactured in compliance with existing EMI (Electromagnetic Interference) requirements, use of this system in the presence o an electromagnetic field can cause momentary degradation of the ultrasound image. If this occurs often, MEDISON suggests a review of the environment in which the system is being used, to identify possible sources of radiated emissions. These emissions could be from other electrical devices used within the same room or an adjacent room. Communication devices such as cellular phones and pagers can cause these emissions. The existence of radios, TVs, or microwave transmission equipment nearby can also cause interference.

y The following precautions can help to reduce ESD:

- Anti-static spray on carpets or linoleum

- Anti-static mats

- A ground wire connection between the system and the patient table or bed.

Chapter 2. Safety

2-8

CAUTION

In cases where EMI is causing disturbances, it may be necessary to relocate this system.

2.3.5 EMC The testing for EMC(Electromagnetic Compatibility) of this system has bee performed according to the international standard for EMC with medical device (IEC60601-1-2). This IEC standard was adopted in Europe as the European nor (EN60601-1-2).
