The utility model relates to a
lung function appearance technical field provides a kind of
lung function appearance calibration device, including
workbench, the top of the
workbench is close to left side fixed installation has pump
machine, the left side fixed installation of pump
machine has first air outlet pipeline, the inner wall left side fixed embedding of first air outlet pipeline has connecting pipeline, the left side fixed installation of first air outlet pipeline has first
gasket, first
gasket fixedly covers the outer surface of connecting pipeline, the utility model, when using, not only can be through the cooperation of first
gasket and second gasket, ensure the sealing between the air inlet pipeline of
lung function appearance and calibration device, to avoid air leakage problem, ensure that gas flow accurately reaches
lung function appearance, ensure the accuracy of calibration process, simultaneously when pump
machine operates, by flowmeter real-time measurement air flow, ensure the accurate collection of gas flow data, provide reliable basis for the calibration of
lung function appearance.
