Description

Device is tempered to internal medicine lung capacity is breathed to children

Technical Field

The invention relates to the technical field of medical assistance, in particular to a respiratory capacity exercise device for children in respiratory medicine.

Background

The vital capacity refers to the total amount of gas that is exhausted after a single effort to inhale. The vital capacity is tidal volume + inspiratory volume + expiratory volume. Tidal volume refers to the amount of gas inhaled or exhaled per breath. The amount of the supplementary inhalation is called the reserve amount of inhalation, which means the amount of gas inhaled after the last quiet inhalation and the best inhalation. The supplementary expiratory volume is called the reserve expiratory volume, which refers to the volume of gas that can be exhaled by the patient after the patient calms the end of expiration. The lung capacity is the maximum ventilation of a breath and may in a sense reflect the potential capacity of the respiratory function. After the national physical health standards of students are out of the shelf, the students become new troubles for a plurality of parents, some children have small inherent vital capacity and are reluctant to even not reach the vital capacity passing standard, and other children can not control the breathing and have the conditions of oxygen deficiency and dizziness. It is important and very necessary to improve the vital capacity of children, and apart from physical exercise tests, the heart and lung functions of the children can be enhanced, the morbidity of tracheitis, asthma and pneumonia can be effectively avoided, and the increase of the vital capacity can also promote blood circulation, so that the children are energetic.
