[0002] With the acceleration of the modern social life rhythm and the aggravation of environmental pollution, respiratory diseases have become one of the important factors affecting people's health. Respiratory diseases not only affect the daily life and working ability of patients, but may even endanger life in severe cases.

[0003] Respiratory medicine is a medical specialty dedicated to the research and treatment of respiratory diseases. It covers diseases in the chest regions such as the lungs, bronchi, pleura, and mediastinum. Respiratory medicine mainly focuses on the diagnosis, treatment, and prevention of airway and lung diseases, and is committed to helping patients restore or improve their respiratory function. The diseases involved in this department are diverse, including pneumonia, tuberculosis, chronic obstructive pulmonary disease (COPD), asthma, lung cancer, etc. These diseases may cause symptoms such as cough, expectoration, shortness of breath, and chest pain, seriously affecting the quality of life of patients. Respiratory medicine plays an important role in ensuring people's respiratory health. With the continuous progress of medical technology, the treatment means of respiratory medicine are becoming increasingly rich and precise, providing more and better treatment options for patients.

[0004] In the rehabilitation treatment of respiratory medicine, vital capacity training is an important means to restore the respiratory function of patients. Vital capacity training improves the ventilation function of the lungs by increasing the strength and endurance of respiratory muscles, thereby improving the respiratory condition of patients. In response to the above problems, some vital capacity training devices for assisting in the restoration of respiratory function have emerged on the market. Most of these devices use mechanical or electronic means to simulate respiratory movements and assist patients in vital capacity training. However, the existing training devices still have some deficiencies in terms of structure, function, and use effect. For example, some devices have complex structures and inconvenient operations, making it difficult for them to be widely accepted by patients; some devices have single functions and cannot meet the rehabilitation needs of different patients; and some devices can simulate respiratory movements, but the training process lacks pertinence, resulting in unsatisfactory training effects.

[0005] To solve the above problems, the utility model patent proposes a vital capacity training device for assisting in the restoration of respiratory function. The device aims to improve the pertinence and effectiveness of the training process by optimizing the structural design and function settings, thereby better helping patients restore their respiratory function. At the same time, the device also has the characteristics of simple operation and comfortable use, and is easy to be accepted and used by patients. Content of the Utility Model
