technical field

The invention belongs to the field of lung capacity training, and in particular relates to a lung capacity training device for respiratory medicine.

Background technique

Respiration is the process of gas exchange between the body and the external environment. The human respiration process includes three interrelated links: external respiration, including lung ventilation and lung ventilation; gas transportation in the blood; internal respiration, which refers to the gas exchange between tissue cells and blood. A normal adult breathes 6.4 seconds at a time when it is quiet, and the amount of gas inhaled and exhaled each time is about 500 ml, which is called tidal volume. According to the survey, the reduction of lung capacity makes people more likely to develop a variety of lung health diseases in old age, such as bronchitis, asthma and other diseases, and the lung capacity may also be reduced due to lung surgery or laryngeal surgery.

However, the existing breathing equipment cannot clean the pipes for breathing backflow. After long-term use, the pipes will accumulate excessive saliva and bacteria, resulting in measurement errors or cross-infection of respiratory diseases.
