Description

Technical Field

[0001] This utility model relates to the field of respiratory training equipment technology, and in particular to a respiratory muscle training device. Background Technology

[0002] During respiration, the human body exchanges gases through the contraction and expansion of the diaphragm and internal intercostal muscles. Studies have shown that appropriate exercise can improve the strength of the respiratory muscles. When pilots are under G-forces, the lungs are subjected to several times the normal stress, resulting in insufficient gas exchange and further affecting bodily functions. Systematic respiratory muscle training can significantly improve a pilot's G-force tolerance.

[0003] However, existing respiratory muscle trainers typically employ a constant load impedance respiratory muscle training method, which cannot simulate the respiratory resistance at different altitudes.

[0004] Therefore, a respiratory muscle training device is provided to solve the aforementioned problems existing in the prior art. Utility Model Content
