The invention discloses a control device for collecting and stabilizing the flow rate of exhaled air. The present invention utilizes the feedback of the pressure sensor and the size of the caliber of the rotating gas passage to realize the collection of exhaled gas at different flow rates under correspondingly set constant pressures. Other uses.
Description
technical field [0001] The invention relates to a control device for exhaled gas collection with stable pressure and flow rate. Specifically, it uses pressure sensor feedback and the size of the caliber of the rotating gas passage to realize the collection of exhaled gas at different flow rates under different settings and constant pressures. The device is mainly aimed at the needs of Exhaled breath collection with controlled expiratory flow or pressure. Background technique [0002] Human exhaled breath contains a variety of human metabolites, namely biomarkers, including volatile organic compounds such as acetone, isoprene, nitric oxide, carbon monoxide and other substances. Analysis of substances in exhaled breath is of great significance as a non-invasive diagnostic method for corresponding diseases, and it is also a hot topic in current clinical research. However, the measurement of some biomarkers in exhaled breath has a certain flow rate dependence, and different con...
