Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a lung capacity training device. Background Art

[0002] When a person breathes normally, the diaphragm and external intercostal muscles are active. The activity of these muscles causes changes in the chest cavity space, achieving the purpose of breathing. The respiratory trainer uses the basic principle of impedance training. When the user blows through the respiratory trainer, he needs to exert effort to resist the impedance set by the trainer to achieve the purpose of vital capacity training. The vital capacity training device is an indispensable medical device in all departments of the hospital.

[0003] Publication (Announcement) No.: CN218686117U, discloses a vital capacity training device, in which the user holds the handle, points the mouth to the breathing mask, and blows air into the inside of the connecting tube. After the air pressure inside the connecting tube increases, the piston plate is pushed toward the top of the measuring tube. Since the support spring needs to be compressed when the piston plate rises, resistance needs to be overcome when exhaling to achieve the purpose of vital capacity training, and the height of the connecting plate can be adjusted by using an adjusting screw to adjust the degree of compression of the support spring. The elastic force of the support spring changes, thereby meeting the purpose of adjusting the intensity of the vital capacity training.
