Mindray BeneHeart D6 Defibrillator High Voltage Board 0651-20-76727
Brief Introduction
Mindray BeneHeart D6 Defibrillator High Voltage Board 0651-20-76727
is a board that converts the DC low voltage inside the
defibrillator machine into AC high voltage. The working principle
of the high-voltage board is to convert low DC voltage into high AC
voltage.
Feature
The high-voltage board in the defibrillator is a very important
internal part of the defibrillator. It is mainly an electrode plate
used to deliver defibrillation current to the human body for
defibrillation. Defibrillators have two different working modes.
There are two electrodes on the defibrillator. One-way wave
electric defibrillation can only emit current once. The time for
the current to flow through the body is determined by the
resistance of the body. It is a one-way current, so defibrillation
is It requires a large amount of energy (360J). Bidirectional wave
defibrillation can also send out a reverse current after sending
out a current, and can control the time of current flow. The
current flows through the body twice, so defibrillation requires
The energy is small (150J-200J).
The voltage of the defibrillator is converted from the high-voltage
plate to convert the DC low voltage into a pulse high voltage.
After the high voltage is rectified, it charges the energy storage
capacitor C and stores a certain amount of energy in the capacitor.
During treatment, the high-voltage plate is controlled to release
the energy stored in the capacitor C.
The position of placing the electrode plate, the front end
position: A-below the clavicle on the right edge of the sternum,
B-on the mid-clavicular line in the center of the electrode plate
on the left side of the nipple. Anteroposterior view: A-right
subclavian anterior wall, B-left subscapular posterior wall.
Posterior apical position: A-apex of the heart, B-behind the right
scapular angle.
Causes of damage to the high-voltage board of the defibrillator:
| Left for a long time | If the high-voltage plate of the defibrillator has not been used
for a long time, it may lead to poor contact of the electrode plate
and poor current transmission. |
| Oxidation | Long-term storage and high-temperature environment will cause the
metal electrodes of the high-voltage board to be oxidized,
performance degradation, poor current transmission, high-voltage
board failure, etc. |
| Damage | During use, the high-voltage board may be damaged if it is hit,
bent, scratched, or the cable connection is loosened. |
Repair:
1. Cleaning and Adjustment:
If the high-voltage board of the defibrillator has poor contact or
poor current transmission, it can be solved by cleaning and
adjusting the high-voltage board. (Be careful to use appropriate
cleaning agents to avoid secondary damage.)
2. Replace the high voltage board:
If the damage is serious, the high-voltage board needs to be
replaced with a new one in time to avoid damage to other
components. (It is recommended to use original accessories or
compatible products)
3. Regularly maintain the high-voltage board:
The maintenance of the defibrillator is very important. In order to
reduce damage to the parts within the instrument, the defibrillator
needs to be maintained regularly and damaged parts replaced in a
timely manner to maintain the normal use of the defibrillator.
The high-voltage board of the defibrillator is subject to a lot of
damage, such as long-term placement, oxidation, impact, scratches,
etc. When the high-voltage board fails, clean, adjust, replace,
maintain the high-voltage board, etc. according to the situation.
Strengthening the maintenance of defibrillators can effectively
reduce damage to defibrillator parts.
