How does sugarcane pneumoconiosis return a responsibility?
summary
My husband is a worker in a bagasse processing factory. He usually has to deal with a lot of bagasse. Later, he suffered from headache, sweating, unexplained pain, coughing and fever for a long time. He never had time to see a doctor. Recently, it was very serious. After my persuasion, he went to see a doctor. The doctor took the sputum from her husband to do a test, and took a film of the lung. Finally, he was diagnosed as sugarcane pneumoconiosis and needed immediate treatment. How does sugarcane pneumoconiosis return a responsibility? Now let me tell you something.
How does sugarcane pneumoconiosis return a responsibility?
The cause of pneumoconiosis is the inhalation of dust, but the inhalation of this kind of dust does not necessarily lead to the occurrence of pneumoconiosis. Human respiratory organs have a strong function of preventing dust from entering and depositing in the body, and inhale dust in the air.
First, the filter is blocked by the nasal hair grid, and then affected by the anatomical structure of the nasopharynx, the air flow direction and velocity change, and eddy current is formed in the nasopharynx and nasopharynx. The dust particles are inertia, more than 10 μ M is easy to impact and attach to the upper respiratory tract wall, which can generally filter 30-50% of the dust in the air.
When the airflow enters the lower respiratory tract, with the gradual branching of the trachea and bronchus, the airflow speed slows down and the airflow direction changes. The dust particles in the airflow settle on the mucus membrane of the tube wall. The swing of the ciliated cells under the mucus membrane pushes the mucus to the larynx and discharges with the sputum. Most of the dust retained in this part is in the range of 2-10 μ M size. Most of the dust particles that can enter the alveoli are less than 2 μ m. Most of them are engulfed by phagocytes in the lung and transferred to the surface of bronchial mucosa with ciliated cells through a layer of surfactant covering the surface of alveoli and the relaxation of alveoli.
matters needing attention
Therefore, the deposition of inhaled dust in the lungs only occurs when the amount of inhaled dust is too large and the defense function of human respiratory organs cannot filter, adhere and retain it, or when the dust deposition in the alveoli cannot be completely removed. Therefore, it is of great significance to maintain the good self-defense function of respiratory organs.
