Comen CM1200B ECG display interface board 050-000216-00 Used Spare Parts for CM1200B ECG Machine

■ Product Describe

Comen CM1200B ECG display interface board 050-000216-00 is a disassembled accessory of Comen CM1200B. The accessory model is 050 - 000216 - 00. It is an important component of the ECG display. It connects the display screen and the ECG main control system, and can quickly and accurately complete the conversion and adaptation of data signals, ensuring that ECG data and various information operations can be accurately and stably presented on the display screen, and also transmits the operation instructions of the display screen (keyboard operation) to the main control system of the device. It is equivalent to the "bridge" between the device display screen and the main control system.

■ Product functions

1. Data transmission

The display interface board is responsible for transmitting the 12-lead ECG data collected and processed by the ECG machine, patient information (such as name, age, medical record number, etc.), various measurement parameters (gain, paper feed speed, lead selection, etc.) and system status information (measurement start/end, power status, equipment failure prompt, etc.) to the display screen at high speed and stability, so that medical staff can intuitively obtain these key information and provide a basis for diagnosis.

2. Signal conversion and adaptation

The signal format output by the main control unit of the ECG machine is different from the signal format that the display screen can receive. This interface board can convert and adapt the data signal, convert the digital signal or analog signal transmitted from the main control unit into a signal form that the display screen can recognize and correctly display, and ensure that the display screen presents various information clearly and accurately, such as converting ECG waveform data into the corresponding visual waveform on the display screen.

3. Operation command feedback

When medical staff operate the ECG machine through the buttons around the display screen (such as the numeric keyboard, function buttons, etc.), the interface board will quickly capture these operation command signals and transmit them back to the main control unit of the ECG machine. For example, when the medical staff presses the "Start" button, the interface board will promptly transmit the command to the main control unit to trigger the ECG data collection process; when adjusting parameters such as gain, the command is also fed back to the main control unit through the interface board to complete the corresponding settings.

4. Power management and distribution

It is also responsible for providing a stable power supply for the display screen and managing and distributing the power supply reasonably. It ensures that the display screen can obtain appropriate and stable power in various working states, avoids display abnormalities such as flickering and black screen due to power problems, and ensures that the display screen can always work normally during long-term use of the device.

■ FAQ​

Q1: What are the symptoms of a display interface board failure?

A1: The display screen is black or distorted, the ECG waveform cannot be displayed normally, or the displayed waveform is seriously distorted or disordered. Patient information and measurement parameters may not be displayed correctly on the screen. In addition, when operating the buttons around the display screen, the device does not respond, or incorrect operation feedback appears, such as pressing the "Start" button, the device does not start the acquisition process, etc. These may be caused by a display interface board failure.

Q2: How to determine whether it is a display interface board failure or a display screen failure?

A2: First, check whether the connection line between the ECG machine and the display screen is loose or damaged. Connect the interface line to other displays of the same model. If the display screen can display normally, it may be that the display interface board of the original ECG machine is faulty; if it cannot display normally on other ECG machines, then the display interface board is likely to be faulty.

Q3: Can the display interface board be replaced by yourself?

A3: It is not recommended for non-professionals to replace the display interface board by themselves. This accessory is a medical accessory. If you replace it by yourself, it may cause the device to malfunction.
