Abstract

The invention discloses a whole-lung forced oscillation spectrum detection system composed of a vibration generator and an infrasound sensor which are mutually matched in use. The vibration generator is connected with an oral airway interface through a connecting pipe. The infrasound sensor is provided with a chest strap binding the chest of a patient. The whole-lung forced oscillation spectrum detection system further comprises a computer which is connected with the infrasound sensor. By the detection system which is taken as a supplement to lung functional test, diseases of chronic obstructive lung disease, asthma and the like can be more sensitively diagnosed, and detection performed in calm breathing with no need for cooperation of the patient can reflect the situation of the lung function of the patient, at different parts. The whole-lung forced oscillation spectrum detection system can be used for identifying respiratory diseases of the chronic obstructive lung disease and the asthma, evaluating the effect of the treatment, detecting early tumors and the like.

Description

technical field

[0001] The invention relates to a whole lung forced oscillation frequency spectrum detection system. Background technique

[0002] Asthma and COPD are common chronic respiratory diseases with a large number of patients. In recent years, the prevalence rates of asthma and COPD have increased significantly, and the mortality rate has also increased. Chronic respiratory diseases have a high prevalence rate, great harm, late diagnosis, poor curative effect, high disability and death rate, and bring a very heavy burden to the social government, families and patients. Early detection and diagnosis is the key to effectively prevent the development of the disease and improve the prognosis. The 2011 GOLD guidelines suggest that COPD should be diagnosed as early as possible to slow down the progression of the disease.
