Mortara ELI 250 ECG Machine Display Assembly TRULY MTG2119-B1
Used-Good Parts for ECG Machine
■ Product Describe
This is a brand new original accessory for the ELI 250 ECG machine.
It is a used disassembled accessory, but it functions normally. The
accessory model is TRULY MTG2119-B1. It is an embedded LCD display
component that can convert the data detected by the ECG machine
into a waveform graph and display it on the display screen in real
time for medical staff to view. At the same time, it can display
the corresponding parameters such as heart rate, gain, filtering,
and printer paper feed speed and other key parameters. The
parameters can be adjusted by buttons. It is also equipped with a
touch screen function, which is very convenient to use. The display
component uses LED backlight technology, which can automatically
adjust the brightness to ensure the readability of the display in
strong light or dark environments.

■ Functions
1. Display ECG waveform
The detected ECG signal of the patient can be converted into a
dynamic waveform and displayed in real time. By observing these
waveforms, medical staff can judge whether the patient's heartbeat
is normal and whether there are any arrhythmias.
2. Display key data
In addition to the waveform, it will also display the patient's
heart rate, ECG measurement parameters (such as the height and
width of the waveform) and other important information in the form
of numbers and text, so that doctors can quickly understand the
patient's condition.
3. Operation prompts and feedback
When you press the button on the machine to start measurement,
print reports, etc., there will be prompts on the display, such as
"Measuring" and "Printing", and the operation results will be fed
back after the operation is completed, so that the operator can
understand whether the operation is successful.
4. Adjust display settings
It supports simple setting adjustments. For example, if you think
the waveform on the screen is too small to see clearly, or the
color is not suitable, you can use the machine's buttons to adjust
the size, color, brightness, etc. of the waveform on this screen to
make the display effect more in line with your needs.

■ Product Advantages
1. Medical-grade reliability:
The display screen uses a scratch-resistant glass panel, which is
suitable for use in medical environments where frequent clinical
wiping and disinfection are required, and has very high durability.
The display screen has an electromagnetic shielding layer that can
shield external electromagnetic interference, reduce
electromagnetic interference to the equipment, and ensure stable
operation of the equipment.
2. High-definition display:
The display screen has a high resolution and a pixel density of 113
PPI, which can clearly present subtle waveform features (such as P
waves and QRS complexes).
It has a wide viewing angle technology with no obvious color
difference or distortion when observed from multiple angles.
3. Intelligent interactive optimization:
The display screen has a built-in filtering function, which can
automatically filter the 10-second waveform with the lowest noise
within 5 minutes to reduce repeated acquisition.
The function buttons are linked to the screen labels to support
quick switching of display formats (such as 3+1, 6 channels, and 12
channels).
