Patient's Safety - Saadat DENA 1210 User Manual

Patient's safety

Introduction
The DENA 1210 electrocardiograph device is designed to comply with the international safety
standards requirements for medical electrical equipment. This device has floating input
(isolated electricity) and is protected against the effects of defibrillation. If correct electrodes
are used in accordance with the manufacturer instructions, the display screen will recover
within 10 seconds after defibrillation.
Grounding
To protect the patient and hospital personnel, the electrocardiograph system must be grounded.
The DENA 1210 is equipped with a detachable 3-wire cable which grounds the instrument to
the power line ground (protective earth) when plugged into an appropriate 3-wire receptacle.
If a 3-wire receptacle is not available, consult the hospital electricians. If there is any doubt
regarding the integrity of the protective grounding wire, the equipment should run on the
battery.
Equipotential Grounding
Protection class I instruments are already included in the protective grounding (protective
earth) system of the room by way of grounding contacts in the power plug. For internal
examinations on the heart or the brain, the electrocardiograph must have a separate connection
to the equipotential grounding system. One end of the equipotential grounding cable (potential
equalization conductor) is connected to the equipotential grounding terminal on the rear panel
of the device and the other end to one point of the equipotential grounding system. The
equipotential grounding system is for the safety function of the protective grounding conductor
if ever there is a break in the protective grounding system. Examinations in or on the heart (or
brain) should only be carried out in medically used rooms incorporating an equipotential
grounding system. Check each time before use that the instrument is in perfect working order.
Warning
• Dena 1210 electrocardiograph is intended to be used only by qualified medical staff.
• Before using the Dena 1210 electrocardiograph, read the user manual and its
accessories thoroughly.
• Dena 1210 electrocardiograph is intended for use only as an adjunct in patient
assessment. It must be used in conjunction with clinical signs and symptoms.
• There could be hazard of electrical shock by opening the system casing. All servicing
and future upgrading to this equipment must be carried out by personnel trained and
authorized by manufacturer.
• The electrocardiograph and devices connected to it should form an equipotential
body to ensure effective grounding.
