GE B20 B40 B125 patient monitor NIBP Module Board 2047656-001

►Quick Detail:

This product is GE B20 B40 B125 patient monitor NIBP Module Board 2047656-001
The gas path detection of the blood pressure module is divided into external and internal gas path detection. This type of malfunction is usually caused by slight air leakage in the pneumatic system. If there is a large amount of air leakage and the machine cannot complete the measurement of blood pressure, the air leakage detection will report "pump leakage". The external air duct consists of an air duct extension tube and a cuff. The simplest and most direct method to check the external air circuit is to use the "substitution method", replacing the external air circuit components (cuff, ventilation tube, quick connector) in sequence. If the fault is eliminated, it indicates that the replaced component is faulty. If there is no problem with the external air circuit, it can be determined as an internal air circuit fault. The internal air circuit mainly consists of an air pump, two solenoid valves, a connector, and several rubber air ducts. We first check if the trachea is damaged, and then tighten the trachea to each connecting head. After troubleshooting these minor issues, if the problem persists, you can perform a leak check on the air pump and vent valve. The method is as follows: enter the NIBP settings menu and press the leak detection button. The air pump starts to inflate. When the air pump stops inflating, use a hemostatic clamp to clamp the trachea connected to the air pump and see if it reports "pump leak" or if the air pressure drops rapidly. If the air pressure remains at a certain value and no longer decreases, it indicates that the air pump is leaking. Similarly, this method can also be used to detect whether two solenoid valves are leaking air. The final inspection revealed a slight air leakage in the air pump, which was resolved by replacing it with a new one.

►How to evaluate the blood pressure monitoring module:

Measurement principle: Oscillometry is an indirect method for measuring arterial blood pressure by blocking the oscillatory waves in the cuff. 2 Testing method: Upper arm measurement. Composed of three sets: digital blood pressure monitoring module, inflation pump, solenoid valve, deflation valve, gas pipeline fittings (five way, silicone tube O-ring), and cuff, etc. 4 Control commands: The module has rich and practical AT commands that can be implemented, including software and hardware version queries, unit queries or conversions, automatic measurement start stop, personalized measurement, air pump start stop, solenoid valve opening and closing, continuous measurement, heart rate cycle data, etc. 5 output data: real-time measurement value U0 (real-time pressure, status) and measurement result U1 (systolic pressure, diastolic pressure, heart rate, and status); Heart rate cycle data. 6 Reference Standards: The following industry standards were referenced during the design process: ① YY0670-2008 non-invasive automatic blood pressure monitor; ② JJG 692-2010 Verification Regulations for Non invasive Automatic Blood Pressure Monitoring Devices. 7 module features: ① Design specifications, relevant parameters meet the requirements of industry standards; ② Serial communication, digital output, rich AT commands, convenient for secondary development; ③ Small size, flexible surface mounting on PCB, convenient for product structural design.
