3.1.10. Sensors for EEG / EOG / EMG
For the neurological channels (EEG, EOG, EMG) all
commonly available types of electrodes with 1.5mm
safety plugs can be used. To connect the electrodes
to the device the splitter box is required. The
green
plug of the splitter box has to be connected to the
green socket of the device.
For application and cleaning of the electrodes please
refer to the manufacturers instructions.
Note: In order to guarantee good adhesion of the
electrodes and strong frequency signals, clean the
desired skin area with a sterile solution and apply a
good quality conductive cream
3.2. Preparing for measurement (Ambulatory)
In preparation of an ambulatory study where the
patient will use the device at home, please ensure
the following:
1. Charge the battery: see (Page 8).
2. Connect the MiniScreen Pro with the USB inter-
face cable.
3. Start the MiniScreen software on the PC.
4.
Fill out the fields relating to personal data of the
patient in the menu item ”Device Connection /
EasyScreen/MiniScreen initialisation“ (or select
the following tab button
) and start the trans-
fer.
5. Switch on the MiniScreen Pro by sliding the
switch to the right. For testing purposes, both
LEDs will light up initially. The red LED will then
go off. The green LED on the MiniScreen Pro
will remain lit for the duration of the initialization
process.
6.
In the next step of the Initialization process, you
have the option to choose Timer Controlled or
Manual recording.
Timer controlled recording start:
A dialogue window will be displayed in order for
the operator to determine the start time for
recording. The MiniScreen Pro needs to remain
switched on after this time!
The unit will now rest in stand-by mode until the
selected Start Time of the recording. The unit
will then automatically switch on and start
recording
data. Never switch off the
MiniScreen Pro sliding switch during use!
Manual recording start:
Once the unit has been successfully initialized
both LEDs will flash confirming ready for use.
The MiniScreen Pro unit now needs to be
switched off sliding the switch to the left. After
fitting the device the patient will need to switch
the unit on before going to bed by sliding the
switch to the right.
7.
The MiniScreen Pro is now ready for use. The
unit can now be disconnected from the PC.
Note : remove cable by pulling on the plug - not
on the cable.
3.3. Attaching the MiniScreen unit and starting
the measurement
In order to ensure reliable recording of data, you
need to observe the following points when attaching
the MiniScreen Pro and sensors. Before ambulatory
measurements these steps should be demonstrated
and practised with the patient beforehand in the
clinic:
1. If applicable, attach the ECG electrodes.
2.
Secure the MiniScreen Pro to the thorax using
the elasticated thorax belt (with the
two built in
pockets). Apply the belt whilst in the standing
position and exhale. A correctly fitted belt should
not slip up or down once fastened. To record
abdominal breathing, attach the abdominal belt
(with the
single built-in pocket) around the
stomach in the same way. Always ensure the
belts are fitted over the night clothes and not
directly onto bare skin.
3. Check the position of the pressure transducers
(black rubber pads). The sensors should be fully
inserted into the built-in pockets sewn onto the
belt.
Never pull on the tubing connected to
the pressure pads
.
4. Apply the flow prong and/or respiratory ther-
mistor to the nose or fix the adapter hose to the
CPAP mask.
5. If applicable, attach the leg sensor, the
microphone and the neurological splitter box.
6. Apply the finger sensor (SpO2) to a finger and
secure the cable to the wrist using the Velcro
wrist band. Whilst doing so, ensure that you do
not
apply pressure to the finger thereby
disturbing the blood flow.
7. If no automatic start was predefined the Mini-
Screen Pro has to be switched on using the
slider
(towards the right). Otherwise the
MiniScreen will automatically switch itself on at
the predetermined time. Both LEDs light up
briefly for testing purposes.
If all sensors have been connected correctly, the
red LED will go out. The green LED blinks at
regular 4 second intervals.
The red LED signals a faulty pulse signal. Check
the finger sensor and cable.
Once the patient has been educated on fitting the
device, the device can then be packed into its hard
carry case for the patient to take home. The patient
can refer to the quick reference guide when fitting the
device at home.
