Description
technical field [0001] The invention relates to the technical field of lung function testing, in particular to a novel and improved breathing filter device and its application method. Background technique [0002] In the traditional pulmonary function test process, the equipment used is a connected mouthpiece and breathing filter, and during the test, the tester’s nose needs to be clamped with a nose clip, but the tester’s nose is clamped by the nose clip In the process of clamping and testing, the tester will feel uncomfortable psychologically and physically, and the tightness of the nose clip may cause air leakage during the test process, resulting in inaccurate test results. For this reason, we have proposed a new type of improved breathing filter device and its application method. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a novel and improved breathing filter device and its applic...
