Welch spot vital signs Lxi NIBP board 400387 BOM C ASSYF 701549 PATTERN In Stock and Available with Fast Shipping

Welch Allyn Spot Vital Signs Lxi NIBP board has two part numbers: 400387 BOM C ASSYF and 701549 PATTERN. The two models differ only in production batch; otherwise, they are identical and interchangeable. This NIBP board is primarily responsible for driving the NIBP pump, processing pressure signals, and calculating blood pressure parameters. It can measure blood pressure in people of varying ages and body types, enabling accurate blood pressure measurements for adults, children, and neonates. The circuitry utilizes a medical-grade shielded design to ensure stable operation in the complex electromagnetic environment of hospitals.

1. Pressure Signal Acquisition and Processing

   The built-in pressure sensor monitors pressure changes within the cuff in real time, converts the pressure signal into an electrical signal, and then digitally processes it.

2. NIBP Pump and Valve Control

   Drives the NIBP pump motor to control the inflation rate, ensuring the cuff pressure quickly reaches the preset value.

   It also controls the solenoid valve for step-by-step deflation. In an emergency, it triggers the mechanical pressure relief valve for rapid deflation, ensuring patient safety.

3. Blood Pressure Parameter Calculation

   This function uses Weilun's improved oscillometric algorithm to identify systolic, diastolic, and mean blood pressure.

   It supports measurement ranges for adults, pediatric patients, and neonates, with an accuracy of ±3 mmHg or ±5%.

4. Measurement Process Management and Exception Handling

   This function controls the complete measurement cycle: inflation → pressure stabilization → deflation → calculation → result output, all in 45 seconds or less (adult mode).

   Real-time measurement anomaly detection: Immediately terminate the measurement and output an error code if a cuff leak or poor signal quality is detected.

   A retry mechanism automatically restarts after a single measurement failure (up to three times), reducing manual intervention.
