Lung function testing system and method

Abstract

The invention provides a lung function testing system. The system comprises an indicating unit, a collecting unit, a processor and a storage medium; the indicating unit is used for outputting respiratory mode guiding signals; the collecting unit is used for collecting respiratory data in the respiratory process of a testee; the processor is connected with the indicating unit and the collecting unit; the storage medium is used for storing multiple instructions, wherein when the instructions are executed by the processor, the processor calculates the respiratory data and compares the data with apreset condition to obtain a processing result, and the indicating unit is controlled to output the respiratory mode guiding signals according to the processing result. The invention further providesa lung function testing method. By arranging the indicating unit on the lung function testing system, the indicating unit outputs the respiratory mode guiding signals to guide the testee in respiration, the difference in artificial guidance is reduced, and the application range of lung function testing is greatly expanded.

Description

technical field [0001] The invention belongs to the technical field of medical detection, and more specifically relates to a pulmonary function testing system and a testing method. Background technique [0002] Forced vital capacity (FVC), static vital capacity (SVC), and maximum ventilation (MVV) are commonly used indicators for lung function tests. When the subject performs a lung function test, it is necessary to breathe as required according to the type of the lung function test index in order to obtain valid test data. At present, during the pulmonary function test, the subjects usually breathe under the guidance of medical staff, which limits the scope of application of the pulmonary function test; and the human guidance varies greatly, which reduces the accuracy of the pulmonary function test results. [0003] The present invention provides a new pulmonary function test system and test method. By setting an indicator unit on the pulmonary function test system, the in...
