Spirometry, masks with lung function testing and breathing training devices

technical field

The invention relates to a lung function detection device, and specifically designs a lung function meter. The invention also relates to a mask and breathing training device with lung function detection.

Background technique

Respiratory diseases, including asthma, chronic bronchitis, emphysema, etc., are very common diseases that seriously endanger human health. Through drug treatment, although the effect can be seen within a period of time, it often recurs and cannot be cured. The reason is that it only focuses on passive treatment measures such as phlegm removal and anti-inflammation, but does not effectively train the respiratory trachea and respiratory muscles.

Inspiratory breathing training, as the name suggests, is to train the muscle groups that will be used when inhaling in the process of breathing. Inhalation is an active process that requires active contraction to expand the chest cavity and lower the pressure in the lungs: when the pressure in the lungs falls below atmospheric pressure, air is drawn into the lungs. The diaphragm and the external intercostal muscles are responsible for normal inspiration (quiet inspiration). When the diaphragm contracts and the external intercostal muscles contract, the diaphragm moves downward and the chest moves outward and upward at the same time. The volume of the thoracic cavity Larger, correspondingly, the pressure becomes smaller and atmospheric air is drawn into the lungs. However, when inhaling forcefully or taking a deep breath (forced inspiration), in addition to the contraction of the diaphragm, the assistance of the inspiratory auxiliary muscles, the thoracomastoid, trapezius, scalene and external intercostal muscles, is also required. The contraction of the choromastoid muscle makes the sternum lift up, and the contraction of the scalene muscle makes the upper ribs lift up; the result of these muscle contractions makes the chest wide and lift up, and the chest space expands to the limit. The inspiratory muscles can be trained with some supplementary equipment that provides some appropriate resistance, just like the bells of the general arm muscles. Trained inspiratory muscles can increase the depth and breadth of breathing, increase the efficiency of breathing, and further improve the performance of exercise.

The exhalation is done in the same way as the inhalation because of the pressure difference, but the exhalation is because the pressure in the lungs is greater than the atmospheric pressure. In normal passive expiration, there is no muscle contraction. When the diaphragm and external intercostal muscles relax, the chest cavity becomes smaller and the pressure in the lungs increases, so air is spit out from the body. However, when the external air flow is obstructed, or for some patients who have suffered or suffered from chronic lung diseases, exhalation is not completely a relaxing process, but requires the participation of the expiratory muscles. When exhaling vigorously (activeexpiration), the internal intercostal muscles and abdominal muscles responsible for exhalation begin to contract; the contraction of the internal intercostal muscles moves the ribs down, and the contraction of the abdominal muscles also moves the ribs down to compress the abdominal viscera, forcing the diaphragm The membrane protrudes upwards, so that the volume of the chest cavity is minimized, and the intrapulmonary pressure is increased to the maximum, so that the carbon dioxide in the body can be exhaled in large quantities.

Exhalation breathing training has a significant effect on the efficiency of gas exchange in the body.

At present, there is no effective lung function detection device that can accurately measure the pressure value of each breath of people, and there is no portable device with lung function detection. In addition, traditional breathing training devices rely on mechanical structures to control the depth of breathing of the trainee. Various disadvantages of being inaccurate and not portable.
