• Select a room with complete infrastructure.
• Set the device on a flat level worktable. Avoid too strong vibration
or impact when moving it.
• A perfect power system and grounding is need in room, otherwise,
it may hurt patient.
• If there are any questions for the integrality of protective grounding
cable, the device must be run with built-in power supply.
• Both AC frequency and voltage should accord with the requirement,
and current capability is enough.
• The AC power lines should have 3 cores, otherwise the shock hazard to
the patient or operator may be caused.
• Keep device from water, don’t use or store it in the place with the air
pressure, humidity or temperature over the standard, bad ventilation,
the air with sourness, salt, alkali, chemical medicine or too much dust,
or the danger of airleak.
• There should be no high-power device, such as high voltage cable,
X-ray or ultrasound device or electrotherapeutical device.
• If this device is used with cardiac defibrillator or other electric stimulating
devices at the same time, please choose Ag/AgCl chest electrodes.
• If the defibrillation time is over 5 seconds, the one-off chest electrode
should be used to prevent the metal electrode from burning patients’
skin. It is better not to use this device with other electric stimulating
devices simultaneously. If it is necessary, there must be professional
technician guiding on the scene.
• In the process of device operation, doctor should be in the operating
place all the time and observe the patient carefully. Cut off the power
or take off the electrode when necessary to ensure patient’s security.
• After operation, turn all of the function state back to the original state
before turning off. Take off the electrode gently without forcible pulling.
Clean device and all accessories for the next use.
• With over loading, amplifier saturation or lead off, device can prompt
working failure.
• The device and all accessories should be performed maintenance
and overhaul termly (the period should be no longer than half a year).
• Electrocardiograph is a kind of measuring device, should be send to the
related department to test termly following local regulation. The test
cycle should not be more than 1 year.
