Edan XM1 module SpO2 board 21.53.451145-1.0 02.05.250218-101 for patient monitor 

► Brief Description

The SpO2 board (part number 21.53.451145-1.0) is designed for the Edan XM1 module. It is a compact, green-colored board made of metal that fits the module perfectly. Bearing the manufacturer's brand and part number, it is a genuine OEM component that is CE certified. This dedicated, independent data acquisition sub-board is responsible for the acquisition, filtering, and transmission of signals for SpO2, pulse rate, and perfusion index (PI). It features excellent temperature and aging resistance, capable of withstanding internal temperature fluctuations and exposure to disinfectant vapors over the long term without suffering from circuit breaks or solder pad detachment. The board integrates an infrared/red light source driver chip, a high-precision photoelectric signal amplification unit, an analog-to-digital conversion module, and dedicated isolation circuitry, forming a complete signal chain for SpO2 acquisition and digitization.

►Core Monitoring Functions

1.SpO₂: Real-time monitoring of blood oxygen levels.

2.Pulse Rate: Extraction of pulse rate values from the blood oxygen waveform.

3.Perfusion Index (PI): Simultaneous output of PI to assess peripheral perfusion; signal processing is optimized specifically for patients with shock, poor peripheral circulation, or hypothermia.

4.Signal Acquisition: Handles signal acquisition and filtering.

1. Interference Rejection: The circuit board utilizes medical-grade, double-layer ENIG (Electroless Nickel Immersion Gold) PCB technology and features electrical isolation from the NIBP air pump and ECG circuitry. This design eliminates electromagnetic interference caused by inflation-related vibrations, high-frequency electrosurgical units, and other ward equipment, while effectively minimizing reading drift caused by motion artifacts or high-intensity ambient light.

►Detailed Installation Steps

1.Open the module housing: The XM1 module housing features a snap-fit ​​design, allowing for quick opening and closing without the need for screws.

2.Locate the SpO2 board: Once the housing is opened, the SpO2 board is found within a dedicated internal compartment, separated from components such as the ECG board and NIBP valve assembly.

3.Disconnect the old board: Carefully disconnect all cables attached to the SpO2 board.

4.Remove the old board: Unscrew the mounting screws securing the SpO2 board, then gently lift it out of the compartment.

5.Install the new board: Align the new SpO2 board (21.53.451145-1.0) with the mounting holes and snap-fit points inside the compartment; gently push it in until fully seated, then retighten the mounting screws.

6.Connect the cables: Reconnect the J1 and J2 connectors by reversing the disassembly steps. Ensure the connections are secure and free of looseness.

7.Close the housing: Align the front and rear sections of the module housing and press gently until all snap-fit tabs click securely into place.

8.Functional test: Insert the XM1 module back into the main monitor unit, power it on, and connect the SpO2 probe. Verify that the SpO2 waveform and readings display correctly to confirm a successful installation.
