The utility model discloses a platform for noninvasive ventilator development experiment tests. The platform comprises an air source unit, a main control unit, a signal acquisition unit, a monitoring display unit, a heating and humidifying unit, an airflow analysis unit, and a breathing simulation unit. The monitoring display unit comprises an external user display interface and an internal parameter monitoring interface. All of the above components are integrated onto one platform. The signals of sensors in the signal acquisition unit are collected and sent to the main control unit. Detection and control are performed on the airflow in the air source unit by the main control unit through a specific program algorithm according to the acquired signals. The system working state information and the variation of each parameter are then displayed through the monitoring display unit on a real time basis. The experiment test platform has advantages, such as high test accuracy, comprehensive data acquisition and parameter adjustment, convenient and efficient debugging, intuitive test result display, etc., and strong test technical support is provided for the development of new noninvasive ventilator products, so that the product quality can be improved, and the development cycle can be shortened.
