A portable multifunctional cardiopulmonary function testing device and testing method thereof

Abstract

A portable multi-functional cardiopulmonary function test device, which can simultaneously meet the three pulmonary function test requirements of cardiopulmonary ventilation test, dynamic cardiopulmonary ventilation test in six-minute walk test and exercise cardiopulmonary ventilation volume test; the device includes a gas collection module, a gas Analysis host module and screen display module; the gas collection module is used to transmit the respiratory gas flow signal and the exhaled gas sample to the gas analysis host module; the gas analysis host module is used for exhaled gas sample concentration detection and gas volume calculation; the The above-mentioned screen display module is mainly used for displaying the real-time data of the real-time pulmonary function parameters, and exporting the data after the test. The portable multifunctional cardiopulmonary function test device of the present application is small in size, easy to carry, has various functions, and is simple in test operation.

Description

technical field [0001] The present invention relates to the technical field of medical devices, in particular to a portable multifunctional cardiopulmonary function testing device, and also relates to a testing method of the portable multifunctional cardiopulmonary function testing device. Background technique [0002] In recent years, with the trend of population aging, the number of patients with chronic obstructive disease (COPD) has increased dramatically. COPD is a lung disease characterized by not fully reversible airflow limitation, and it is a chronic respiratory disease with a high mortality rate. [0003] Relevant studies have shown that pulmonary function tests are the gold standard for diagnosing and evaluating COPD. Pulmonary ventilation tests can determine the severity of airflow obstruction. However, airflow obstruction is only part of the early manifestations of COPD. Before airflow obstruction occurs, motor function Abnormalities have already appeared, and m...

Problems solved by technology

Therefore, the monitoring of lung ventilation volume and gas metabolism function can detect early lung lesions in time; in addition to exercise cardiopulmonary ventilation volume testing, the six-minute walk test is a way to assess the functional status of patients with moderate and severe cardiopulmonary diseases. Exercise test, however, this test only tests the walking distance, and the ventilation volume data during walking cannot be obtained at the same time, and the information is less. At the same time, the current exercise ventilation volume testing equipment is bulky, not portable enough, and has a single function
