Medical ultrasound scanner is a medical device widely used in clinical diagnosis, which uses high-frequency sound waves to non-invasive, real-time, and high-precision imaging of the internal structure of the human body, providing doctors with accurate diagnostic basis for patients. In the diagnosis of respiratory diseases, medical ultrasound scanners play an important role, effectively helping doctors identify and evaluate various respiratory diseases, such as pneumonia, bronchitis, emphysema, etc. This article will explore in detail the application of medical ultrasound scanners in the diagnosis of respiratory diseases.

2、 The working principle of medical ultrasonic scanner

The working principle of medical ultrasound scanners is to use the reflection and propagation characteristics of high-frequency sound waves to non-invasive detect the internal structure of the human body. When a high-frequency sound wave is emitted into human tissue, it will reflect back a portion of the sound waves when encountering different tissue interfaces. These sound waves are received and converted into image signals, thereby presenting the internal structure and morphology of the human body on the display.

3、 Application of medical ultrasound scanner in the diagnosis of respiratory system diseases

Diagnosis of pneumonia and bronchitis

Pneumonia and bronchitis are common respiratory diseases, and early diagnosis is of great significance for treatment and prognosis. Medical ultrasound scanners can detect the range, location, and degree of lung lesions in real-time and non-invasive manner, helping doctors develop appropriate treatment plans. For example, pneumonia patients can observe local moist rales in the lungs under ultrasound scanning, while bronchitis patients' ultrasound images show dry rales.

Diagnosis and evaluation of emphysema

Emphysema is a chronic respiratory disease characterized by decreased elasticity of lung tissue and decreased gas exchange capacity in the lungs. Medical ultrasound scanners can assess the severity of emphysema by observing lung morphology and respiratory movement. In the ultrasound images of patients with emphysema, the lungs exhibit significant changes in lung parenchyma, such as alveolar enlargement and decreased lung tissue elasticity.

Diagnosis and localization of pleural effusion

Pleural effusion refers to the accumulation of excessive fluid in the pleural cavity, often caused by inflammation, tumors, and other reasons. Medical ultrasound scanners can effectively diagnose and locate pleural effusion, providing accurate basis for further treatment. In ultrasound images, changes in the pleura and the location of fluid accumulation can be clearly observed.

4、 Conclusion and outlook

Medical ultrasound scanners have important value in the diagnosis of respiratory diseases, which can effectively help doctors identify and evaluate various respiratory diseases. With the continuous progress of medical technology, medical ultrasound scanners are also constantly developing and optimizing, and their image quality, accuracy, and application range will be further improved. In the future, medical ultrasound scanners will be more portable and intelligent, and can better serve clinical diagnosis and treatment. Meanwhile, with the continuous application of technologies such as big data and artificial intelligence, the auxiliary role of medical ultrasound scanners in the diagnosis of respiratory diseases will become more significant.

5、 Conclusion

In summary, medical ultrasound scanners play an important role in the diagnosis of respiratory diseases. Its non-invasive, real-time, and high-precision characteristics make it a powerful assistant for clinical doctors. With the continuous development of technology, the application range and accuracy of medical ultrasound scanners will be further expanded and improved, providing more reliable and effective means for the diagnosis and treatment of respiratory diseases.
