Electrostatic Discharge Precautions

General information
Voluson™ SWIFT / Voluson SWIFT+ Instructions For Use
5831612-100 Revision 4
Caution
Do not apply excessive force when inserting or manipulating endocavity probes.
Regularly inspect probes and biopsy equipment for sharp edges or rough surfaces that could
injure sensitive tissue.
Warning
If 3D/4D probes are operated in continuous 4D mode for an unusually long period of time, 30
minutes, the surface temperature of the handle might get warm and exceed limits according to
IEC60601-1. Continuous use of 4D mode should not exceed 30mins.
If 3D/4D probes are operated in continuous 4D mode for an unusually extended period of time,
the surface temperature of the handle might get warm and exceed the limit according to
IEC60601-1. The temperature of the applied part will stay within the limits according to
IEC60601-2-37.
Electrostatic discharge (ESD), is commonly referred to as electric static shock, which is a
naturally occurring phenomenon that results in the flow of an electrical charge between
differently charged objects or persons. ESD occurs more frequently during conditions of low
humidity, that can be caused by e.g. heating or air-conditioning. At low humidity conditions,
electrical charges naturally build up on individuals and objects and can lead to static
discharges. The following cautions help to reduce ESD effect:
Caution
•
Do not touch connector pins on the probe connector or the console.
•
Handle the probe by the metal connector shell.
•
Make contact with a metal surface of the console before connecting a probe to the
console.
•
The following precautions help reduce ESD:
anti-static spray on carpets, linoleum and mats
○
a ground wire connection between the console and the patient table or bed
○
•
Observe ESD precautions when handling or connecting probes.
Typically an ESD/EMC event results in an intermittent ultrasound image degradation for the
time the ESD/EMC event is present. In rare cases the ultrasound system might show an error-
message that can be confirmed by the operator. In other cases the ultrasound system might
stop to operate and require a re-boot to re-establish the functionality.
Observe the following information:
•
Sporadically, silicone grease can leak in small amounts from the probes' cable bushing.
This leakage is not a failure or harmful to the human body. Silicone grease does not
contain any hazardous substances and is only used to seal the cable bushing. In case of
a leakage wipe the grease with a cloth.
•
Thermal safety: Maintaining a safe thermal environment for the patient has been a
design priority at GE ULTRASOUND KOREA, LTD. . The operating temperature of the
applied part of the probe stays below 43˚C if used as intended.
•
Probes may generate slight noise emissions when operated in volume mode.
•
The high elasticity of the probe surface ensures an optimal coupling of the probe. This
elasticity can lead to small deformations of the applied part. The intended use of the
probe will be in no way affected by this deformation, and leads to no loss of the
ultrasound image quality.
