This invention discloses a multi-condition self-traceable calibration method and system for insufflators, relating to the field of insufflator metrology technology. The method includes: constructing a standard loop to apply back pressure and inject a controllable leakage; during a continuous calibration, controlling the insufflator under calibration to sequentially enter pressure stabilization, flow stabilization, and leakage disturbance conditions, synchronously collecting data through collaboratively working traceable pressure and flow references; comparing the reference measurements with the insufflator's readings to calculate pressure coupling error, flow coupling error, and dynamic response characteristics; performing standard state conversion based on preset standard pressure and temperature, fitting and generating calibration coefficients to correct the measured values, and generating a judgment result based on comparison of coupling error and dynamic response characteristics with preset thresholds; generating an automatic report including operating condition type, residual, final calibration measurement results, and uncertainty. This invention improves calibration accuracy and traceability through three-condition linkage calibration and environmental factor compensation.
