Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training, and particularly relates to a pulmonary function trainer. Background Art

[0002] When training pulmonary function, it is necessary to train the respiratory muscle groups. The vital capacity can generally be practiced through the following methods: chest expansion exercise. Stretch the arms straight, with the palms facing down, slowly and forcefully expand the chest to both sides, then place the arms on both sides of the body, inhale when the arms are lifted, and exhale when the arms are retracted. At the beginning of the exercise, 50 times can be done first, and then slowly increased to 100 times. Stretch exercise. Stretch the arms straight, lift them up, then slowly stretch them behind the head, then place the arms on both sides of the body, inhale when the arms are lifted, and exhale when the arms are retracted.

[0003] The invention patent CN113893505A discloses a pulmonary function training device, belonging to the field of pulmonary function training, including a blowing nozzle.

Two partitions are symmetrically installed inside the front end of the training tube. This invention can adjust the training intensity according to the personal needs of the trainer, and provide progressive training. It can collect the saliva generated during training, and when replacing the collecting bottle, it can prevent the remaining saliva from accidentally flowing out of the device, making it more hygienic. After each training, a sealing mechanism is used to seal between the blowing nozzle and the training tube of the device, avoiding the disgust of the trainer caused by the peculiar smell caused by the remaining saliva during the previous training, and making the training more comfortable.
