Description
Technical Field
The invention belongs to the field of medical equipment, and particularly relates to a lung function examination anastomat and a using method thereof.
Background
The lung function examination is one of necessary examinations of respiratory system diseases, and has important guiding significance for early detection of lung and airway lesions, assessment of disease severity and prognosis of diseases, assessment of curative effect of drugs or other treatment methods, identification of reasons of dyspnea, diagnosis of lesion parts, assessment of tolerance of lung function to operation or labor intensity tolerance, monitoring of critical patients and the like. The pulmonary function test includes ventilation function, respiratory regulation function, pulmonary circulation function, and the like, and there are many test items and measurement indexes. At present, the lung function examination is mainly completed by using a lung function detector, and the lung function detector is medical equipment for examining and detecting the operation condition of the lung function of human beings.
The lung function detector adopts a physical examination method, and has no damage, pain and discomfort to the body. The pulmonary function examination has the advantages of high sensitivity, convenient repeated detection, easy acceptance by patients and the like. Compared with the examination such as X-ray chest radiography and CT, the lung function examination focuses more on understanding the functional change of the lung and an important examination means of respiratory system diseases. Can assist clinical diagnosis, judge the existence of pulmonary dysfunction and the nature and degree of the dysfunction. Is an early diagnosis means for some lung diseases, for example, the early manifestation of the pulmonary interstitial disease can be diffuse hypofunction. Small airway dysfunction may be an early manifestation of chronic obstructive pulmonary disease such as chronic bronchitis pulmonary dysfunction. Can guide clinical treatment, for example, after the bronchodilator is applied to patients with bronchial asthma, the pulmonary function examination can be used as an important curative effect judgment index. Can be used for clinical research, such as airway anaphylaxis determination research of allergic diseases, sleep respiration physiology research, and the like. The lung function measurement before the thoracic surgery patient hand is helpful for judging the completeness of the operation. The effect of dust in the working environment on the lung function and the labor identification can be known in the fields of labor hygiene and occupational diseases.
The traditional pulmonary function tester is connected with a tester by adopting an anastomat, the anastomat structure of the traditional pulmonary function tester is shown in figures 1 and 2, and the anastomat comprises a mouthpiece 4 with a mouthpiece, a blow cylinder 3, a filter 2 containing a filter core material inside and a connecting cylinder 1.
