2. Description of Equipment
2.1 Intended use
The MEDUCORE Easy is an automatic external
defibrillator (AED). It has been devised to assist the
user in the resuscitation of patients who show
symptoms of acute cardiovascular arrest (pulseless
ventricular tachycardia pVT or ventricular fibrillation
VF).
The MEDUCORE Easy guides the user through the
resuscitation process with the help of acoustic and
optical instructions. The device conducts an ECG
analysis on patients and, if necessary, makes
preparations for the delivery of an electric shock. The
delivery of a shock is carried out directly by the user,
after the device has prompted to do so.
Only use the device MEDUCORE Easy for the
purposes described below.
2.2 Scope of application
2.3 User qualification
The MEDUCORE Easy has been devised for
application in the heart/lung resuscitation (HLR) of
patients from upwards of 20 kg body weight at the
emergency’s location.
The MEDUCORE Easy may only be used by persons
who hold documented proof of the following
qualifications:
• Training in fundamental, life saving emergency
care including the application of automatic
defibrillators.
• Instructions for the application of the
MEDUCORE Easy carried out by an
WEINMANN authorized person.
Description of Equipment 5
2.4 Functional description
The MEDUCORE Easy is compact, light and
ergonomic. The acoustic and optical user instructions
make the operation of the device, to a great extent,
self explanatory.
Persons with a nominal medical knowledge, after a
short instruction, can therefore be in the position to
operate a defibrillator in the case of a heart lung
resuscitation.
Optical and acoustic userguide The acoustic and optical user instructions are made up
of display fields and spoken orders.
After opening the device lid the user is led by
MEDUCORE Easy with the help of detailed spoken
orders through a step by step resuscitation process.
During this process a green and red display field light
up, indicating in which phase of the resuscitation the
patient may be touched or not touched (traffic light
principle).
Metronome function
(only for devices with ILCOR 2005)
An activated metronome function gives off an acoustic
metronome signal at a frequency of 100 beats per
minute during the HLR-pause. Carry out the cardiac
massage in rhythm with audible signal tone.
After 30 signal tones a spoken announcement is
issued “Give 2 breaths now” You will now have time
to carry out 2 respiratory sequences, before “Give 30
chest compressions now” is announced and 30 signal
tones are given.
This ordered sequence repeats itself, until the HLR
pause comes to an end and the red display field
(“Stand clear of the patient”) lights up.
If the info button is pressed during the HLR pause, the
info announcement is made. The metronome continues
to run in the background but without an audible tone.
ECG-recording and analysis As soon as the electrodes are placed on the bare
upper body of the patient, the device will
automatically begin with the recording and analysis of
the ECG. The ECG recording and analysis will
continue until the electrodes are removed from the
patient or as soon as the lid of the MEDUCORE Easy
is closed, which results in the device being switched
off.
6 Description of Equipment
Defibrillation If the ECG analysis indicates defibrillation (pulseless
ventricular tachycardia pVT or ventricular fibrillation
VF), the MEDUCORE Easy prepares to deliver a
shock. Afterwards the device instructs the user to
administer a shock.
For other heart rhythms, the device informs the user that
they should carry out a heart-lung revival.
Application documentation The MEDUCORE Easy saves ECG and event data.
The data could later be used e.g. in the follow-up of
treatment. For this, use the documentation and
configurations software EasyView.
Self testing The MEDUCORE Easy initiates a self test at regular
intervals and after every time it is switched on. The
device status is shown via light diodes on its front side.
Self test results can be requested via the documentation
and configuration software EasyView and saved onto
a PC.
Description of Equipment 7
3. Cleaning and disinfecting instructions
Warning!
• The Battery/Rechargeable Battery Pack must be
removed from MEDUCORE Easy before
cleaning.
• Never immerse the MEDUCORE Easy in any
disinfectant or any other liquid. Only carry out
disinfection by wiping over the surface. This can
otherwise lead to damage of the device and
consequently endanger users and patients.
The MEDUCORE Easy can be kept properly clean by
simply wiping to disinfect. Please observe the users
instruction for the disinfectant selected. We
recommend that you wear suitable gloves when
disinfecting the equipment (e.g. household or
disposable gloves).
We recommend that you use TERRALIN disinfectant,
which is available from the Schülke & Mayr
Company, Robert-Koch-Str. 2, D-22851 Norderstedt
(Internet: www.schuelkemayr.de).
8 Cleaning and disinfecting instructions
4. Checking the device
Important!
The device must undergo the following tests after every
repair and every maintenance according to WM 40006,
and the results must be entered into the test records.
Additionally the test can be used for fault finding in the
device.
If you detect errors or deviations from defined values
in the course of your final testing you must not redeploy
MEDUCORE Easy before these errors have been
eliminated.
You can determine possible causes of such errors and
recommended countermeasures by referring to
