CONCORD
Hunan Accurate Bio-Medical Technology Co., Ltd. · Model 75079
Concord Fingertip Pulse Oximeter.
Intended use: An electrically-powered photoelectric device designed for the transcutaneous measurement and display of haemoglobin oxygen saturation (SpO2). The signals are produced by light-emitting diodes (LEDs) and received by a photodetector. The device displays the SpO2 values and may also measure/display pulse rate. It is typically applied to the fingertip or around the wrist, may be single-component (with built-in probe) or multi-component (includes external probe), and may in addition wirelessly transmit measurements to a receiving location (e.g., central station, bedside monitor); it is intended to be operated by laypersons and healthcare providers.
Key tips
- ·A no-signal/flatline alarm gets checked on the patient first, not the monitor - rule out a real clinical event before troubleshooting.
- ·Recalibrate NIBP against a reference manometer, not just a self-test pass.
- ·Reused patient cables (SpO2, ECG leads) are a common source of intermittent-fault complaints - swap the cable before the module.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Will not power on or unexpected shutdown
HighSymptoms: The patient monitoring is dead, reboots, or shuts down mid-use.
Root cause: Mains lead / fuse, an aged battery, or a power-supply board fault.
Battery will not hold charge
MediumSymptoms: Short run time on battery; low-battery alarm soon after a full charge.
Root cause: Aged rechargeable battery pack or a charger fault.
Display / control-panel fault
MediumSymptoms: Blank, dim or distorted display; unresponsive keys or touchscreen.
Root cause: Display, backlight, or control-board fault.
Fails self-test or calibration
MediumSymptoms: Power-on self-test or the scheduled performance check fails or is out of tolerance.
Root cause: Sensor drift or an internal board fault; recalibration or repair needed.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Routine cable and lead-wire inspection for fraying/wear
- ·Battery conditioning cycle
- ·NIBP calibration check against a reference manometer
- ·ECG / SpO2 accuracy verification against a patient simulator
- ·Annual electrical safety test
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Will not power on
- Confirm the outlet, mains lead and fuse.
- Try on battery, then on mains only, to isolate the supply.
- Look for a power indicator or POST code.
- Replace the fuse / battery / power supply as isolated.
- Run the self-test after any repair.
Symptom: Fails self-test or calibration
- Note the exact failure message / code.
- Power-cycle and repeat the self-test.
- Verify against a reference / simulator where one applies.
- Recalibrate per the service manual.
- Refer the affected board for service if it will not hold calibration.
