5) A safety circuit by D.R.M.(Daiwha Return electrode Monitoring)
- To prevent burns, if the contact is lower than 80% of the adhesive area, the output power
is stopped and the alarm will be operated.
6) When the cutting and coagulation and Bi-polar is operated, it can be differentiated by the
sound and the lamp.
7) The output power can be controled by pressing the Up / Down switch on front panel and
be also shown in numbers.
8) Bi-polar is available even if Return Electrode has not been mounted.
3.4 Safety Devices
1) The fuses on power supply stage protects high current.
2) The enclosure is grounded so that the current that may flow to the patient is grounded and
the patient is protected safely.
3) When the Return electrode is separated from the equipment, the high frequency current is
automatically blocked, and you can see the alarm condition by the Return Fault Indicator
and Alarm Sound.
4) Damage or injury to the patient through malfunction or faulty operation is prevented by
use of the input, output priority algorithm.
5) The High Frequency Leakage Monitoring is to monitor high frequency leakage current
from a patient to earth. It reduces the current to lower than IEC Requirement when a
patient grounded to Earth by material part of a bed or any other materials. It reduces the
skin burns at Return Electrode site.
6) The function of the D.R.M.(Daiwha Return electrode Monitoring) is to monitor the contact
area of the patient and the Pad so as to minimize the danger of burns.
7) Isolated Output Circuitry.
This feature minimizes the potential of alternate site burns.
TIP What is D.R.M(Daiwha Return electrode Monitor)?
- As a more advanced safety system than the old Return Electrode Alarm, D.R.M can
avoid the potential burn damage which may result from the little contact area of dual
pad by grace of its monitoring function.
- For single pad
1) Function
: It monitors only the mounting and cable breaking status of Return Electrode.
2) Component
: Single pad or Dual pad Selection Switch, Single pad Mode Lamp, Return Fault
Indicator
3) How to use
①
'Single pad Mode Lamp' lights when applying power to the device as the default is
single pad mode. If you want to use single pad instead of dual pad, replace it and
then press (Single pad or Dual pad Selection Switch) to switch on 'Single
pad Lamp'.
②
Mount Return Electrode to Return Electrode jack by using single pad, metal plate
with cable and rubber plate with cable.
➂
Patch the pad on the patient's body.
