Due to the high sensitivity of the internal pressure
transducer, the MiniScreen device is capable of
measuring and recording ultra fine pressure diffe-
rences associated with patients who mouth breathe.
In order to connect the flow prong, ensure the
blue
connector of the prong attaches into the
blue
connector of the device.
The flow prong should be used in accordance with
the manufacturer’s instructions.
Warning:
The flow prong is intended for single patient use. No
attempt should be made to clean or use the flow
prong the more than once. Multiple use can result in
cross infection!
3.1.2. Thermistor sensor for breathing
Additional to the flow prong a Thermistor can be
used to measure the breathing. Please also observe
the instructions accompanying the sensor.
The
brown
connector of the Thermistor needs to be
attached to the
brown
connector on the MiniScreen.
3.1.3. Sensor for PAP (pressure)
a.) MiniScreen plus
When performing measurements on a patient under-
going PAP therapy, a T-Adapter is used instead of the
flow prong. This is to be placed between the
respiratory mask and the therapy tube at the patient
and is connected to the top of the MiniScreen plus
with the
blue
marked LuerLock connection.
a.) MiniScreen premium
When performing measurements on a patient under-
going PAP therapy, a pressure diff adapter is used
instead of the flow prong. This is to be placed
between the respiratory mask and the therapy tube
at the patient. It has two pressure measuring hoses
with one
blue
and one
yellow
connection.
The near-patient red marked tube has a
blue
con-
nection and is connected to the top of the MiniScreen
premium with the
blue
marked LuerLock connection.
The patient-far colorless tube has a
yellow
connec-
tion and is connected to the top of the MiniScreen
premium with the
yellow
marked LuerLock
3.1.4. Sensor for oxygen saturation and pulse
frequency
A pulse oximeter has been integrated into the device
for the purpose of measuring oxygen saturation and
pulse frequency. A failure of the finger sensor or a
missing data update by the pulse oximeter is
indicated to the user by the red LED on the device. At
the same time the values for SpO2 and pulse are fed
to 0.
Please ensure that blood circulation at the point of
measurement is not affected by the manner in which
the sensor has been secured. Excessive pressure
should not be exerted on the finger, especially if the
temperature exceeds 41 ° C.
When using a finger sensor, please use the Velcro
wrist/armband to secure the sensor and cable. All
nail polish (coloured or clear) must be removed from
the measuring finger to obtain usable data.
To minimize interference (e.g., motion artifacts), the
pulse oximetry values are filtered by digital data
processing. As a result of data averaging and signal
processing, slight delays in the display of the pulse
oximetric values occur. The internal pulse oximeter
works with a time horizon of 4 seconds. By additio-
nally considering the change tendency, the minimum
value of saturation at the end of an apnea is correctly
reproduced. The data is updated at every beat, so
there are no measurable delays due to data refresh
and transmission. Please read and understand the
instructions accompanying the finger sensor.
3.1.5. Sensor for thorax and abdominal
movement
The sensors used for recording thorax and abdomi-
nal movement consists of small rubber pressure
pads that are connected to the MiniScreen device via
measuring hoses. The sensor for recording thorax
movement comprises of two pressure pads whereas
the sensor for abdominal movement contains only
one. The sensors are inserted into the pockets of the
elasticated effort belts. The thorax belt is applied at
the height of the sternum, the abdominal belt in the
stomach region.
For hygiene reasons and to avoid allergic reactions
the belts should be
worn over clothes
.
The
red
connector of the thorax sensor needs to be
attached to the
red
connector and the
black
connector of the abdominal sensor needs to be
attached to the
black
connector of the device.
The effort belts are adjustable in size due to the
Velcro fasteners, and should be suitable for most
