Description

Technical Field

[0001] The present application relates to the technical field of clinical diagnosis of TCM internal medicine, and in particular to a breathing detection device for clinical diagnosis of TCM internal medicine. Background Art

[0002] Breathing refers to the process of gas exchange between the body and the external environment. The human breathing process includes three interconnected links: external respiration, including lung ventilation and pulmonary gas exchange; gas transport in the blood; internal respiration, which refers to the gas exchange between tissue cells and blood. The best breathing time for a normal adult at rest is 6.4 seconds, and the amount of gas inhaled and exhaled each time is about 500 ml, which is called tidal volume. When a person inhales forcefully until he can't inhale anymore; then exhales forcefully until he can't exhale anymore, the amount of gas exhaled at this time is called vital capacity. Testing breathing is to test the gas exhaled by the patient, generally using a breath analyzer for testing.
