Biocare FM-801 Fetal Monitor Mainboard, model 02040119-01, is the "brain" of the Biocare FM-801 fetal monitor. It receives raw data collected by sensors and probes, analyzes, processes, and converts it, and also controls the coordinated operation of other key components.
It is a critical component for ensuring the accurate monitoring and stable operation of the fetal monitor.
This mainboard possesses professional signal analysis capabilities. It amplifies and filters raw signals such as fetal heart rate data and uterine contractions detected by the device. It then converts them into digital signals through a digital signal processor, ultimately transforming them into visible and understandable waveforms. This allows medical staff to understand the fetal condition in the mother's womb and diagnose abnormalities promptly, improving clinical efficiency.
The mainboard controls key components such as the display and printhead through dedicated interfaces. Upon receiving user commands, it accepts and executes them, providing feedback on the display or printhead, meeting the needs of obstetricians and nurses for rapid operation.
The motherboard features comprehensive data management and risk warning capabilities. The motherboard's built-in 128MB flash memory can store ≥1,000 complete monitoring reports and export them for easy reference or archival.
It also issues an alarm when data exceeds preset limits, alerting medical staff to investigate and provide prompt diagnosis.
The motherboard features a built-in self-test circuit that automatically checks each module upon power-up. If any abnormality is detected, a fault code is displayed on the display. Indicator status feedback is also provided, allowing maintenance personnel to quickly locate the problem and minimize downtime.

A1: If the fetal heart rate probe works properly on other devices, then the probe is not a problem. The mainboard signal connection is most likely faulty. Use specialized tools to check. If there's no signal input, the interface is faulty. If there's a signal but no waveform, the mainboard signal processing unit is faulty and the mainboard should be replaced.
A2: This is likely due to an abnormality in the mainboard signal filtering or algorithm. Check for strong magnetic interference around the device. After eliminating it, recalibrate to see if the problem returns. If not, the mainboard filter capacitor or DSP chip is damaged and the mainboard needs to be replaced.
A3: This may be due to a faulty mainboard storage module or file system corruption. Test whether the file can be saved again after formatting. If "USB connection failed" is prompted when exporting data using USB and storage is abnormal, it means that the shared circuit between the mainboard USB interface and the storage module is faulty. Replace the mainboard first.
