3.4. Attaching the MiniScreen unit and starting
the measurement
When apply the sensors, make sure that they are
applied in such a way that strangulation is not
possible due to their length (for example flow prongs,
finger sensor). In order to ensure reliable recording
of data, you need to observe the following points
when attaching the MiniScreen unit and sensors.
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 unit 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
oxygen mask.
5. If applicable, attach the leg sensor and EEG
electrodes.
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. 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.
When going to bed the patient needs to:
•
Attach the MiniScreen using the elasticated
thorax belt.
•
Attach the flow prong and finger sensor.
•
If applicable, attach the abdominal belt, leg
sensor, ECG and EEG electrodes.
•
Check that the sensors and their connectors are
positioned correctly.
The next morning
:
•
The patient has to detach the MiniScreen unit
and sensors and return all parts to the case.
Cleaning of the sensors will be carried out by
the technical staff at the clinic or hospital.
•
Bring the case back to the clinic or hospital.
•
For automatic evaluation the measurement can
be transferred to the PC using the device
software. Select the "Record" tab followed by
"Read measurement from device".
4. Service and Maintaining the device
4.1. Charging the battery
The MiniScreen unit is equipped with a special fast-
charge Li-Ion battery. The battery charging adaptor
included with your device is specially designed for
this type of battery and should only be used with your
MiniScreen unit. It is recommended to charge the
battery completely after each measurement.
Caution: It is not allowed to use a different
battery charger than the one provided!
Battery charging procedure
:
•
Connect the battery charger adaptor to the
MiniScreen device
•
Plug the charger into a power outlet
•
The integrated LED's in the top cover of the
MiniScreen displays the charging status of the
batteries. The device can remain connected to
the charger adaptor for a long period of time
without suffering any damage.
4.2. Cleaning instructions
General
As with any medical device, when using the Mini-
Screen plus / premium polygraphic systems, certain
hygienic procedures are required for safe reuse on
the patient. Reusable products must have safe
disinfectability to exclude any risk of infection from
subsequent users / patients. The regulations of the
Medical Devices Act stipulate that for such medical
devices disinfection activities with procedures accor-
ding to the RKI guideline are to be carried out in
analogy to the methods of surface or instrument dis-
infection. It is recommended to create a hygiene plan
for the MiniScreen plus / premium product. Sterili-
zation of the products listed below is not necessary.
The MiniScreen plus / premium polygraphic systems
are medical devices that are in the patient's environ-
ment when used as intended, with direct contact with
the hands of the staff and the patient. These
products are therefore classified as so-called "non-
critical medical products" in accordance with the
guidelines
for
hospital
hygiene
and
infection
prevention.
