CSIP Level 1 Safety: General Equipment Protection
CAUTIONS • Excessive bending or twisting of cables on patient-applied parts may cause failure or intermit-
tent operation of the system. Take care not to run over cables with the system, which may
damage them.
• In general, only the area of the transducer acoustic window is watertight. Except where
specified in specific transducer cleaning instructions, do not immerse the remainder of a
transducer in any liquid.
• Practice proper cleaning or sterilization of a patient-applied part to avoid damage.
• Do not submerge the cables of patient-applied parts in solution. The cables are not liquid-
tight beyond the applied part/cable or cable/connector interfaces.
• Do not use solvents such as thinner or benzine or abrasive cleaners on the system, transduc-
ers, video monitor, touch screen, or any printer.
About Electro-
static Discharge
Electrostatic discharge (ESD), commonly referred to as a static shock, is a naturally occurring
phenomenon. ESD is most prevalent during conditions of low humidity, which can be caused by
heating or air-conditioning. During low-humidity conditions, electrical charges naturally build up
on individuals and can create static shocks.
An ESD condition occurs when an individual with an electrical energy buildup comes in contact
with objects such as metal doorknobs, file cabinets, computer equipment, and even other indi-
viduals. The static shock or ESD is a discharge of the electrical energy buildup from a charged
individual to a lesser or non-charged individual or object.
The level of electrical energy discharged from a system user or patient to the ultrasound system
can be significant enough to cause damage to the system or transducers. The following precau-
tions can help to reduce ESD: antistatic spray on carpets; antistatic spray on linoleum; antistatic
mats; or a ground wire connection between the system and the patient table or bed.
