Patient Monitor

Specialized repair of multiparameter patient monitors including signal processing boards for ECG, SpO2, NIBP, temperature, respiration and analog/digital outputs. The diagnostic process covers patient isolation circuits, biopotential amplifiers, high-precision A/D converters, cuff pressure control circuits and display systems. Common faults include excessive noise in ECG signals, SpO2 measurement errors, NIBP pump and pressure sensor failures, isolated power supply problems and touchscreen or LED/LCD display failures. All repairs are performed in compliance with medical safety standards IEC 60601 and final calibration is carried out using vital signs simulators to ensure accuracy and patient safety.
