Description

Dual-purpose breathing training ware

Technical Field

The invention relates to the field of rehabilitation training instruments, in particular to a dual-purpose breathing training device.

Background

At present, patients suffering from lung diseases (such as emphysema, chronic obstructive pulmonary disease and the like) or having undergone lung surgery often adopt a breathing trainer to carry out rehabilitation training on the breathing capacity of the patients. In addition, for a healthy person, the breathing trainer can be used to improve the vital capacity and improve the health condition of the body.

In practice, the breathing training can be divided into two parts, namely, the breathing training and the inspiration training, wherein for the inspiration training: when a person normally inhales, the diaphragm contracts and the intercostal muscles contract, when the person inhales forcefully, the person also needs to inhale auxiliary muscles, such as the trapezius muscles and the oblique muscles, the chest is widened and lifted as a result of the contraction of the muscles, the thoracic space is expanded to the limit, the inspiratory muscles need to be exercised, the inspiratory trainer of a respirator adopts the basic principle of impedance training, the user needs to spend effort to resist the impedance set by the trainer when inhaling through the inspiratory trainer, so that the inspiratory muscle strength is increased, the strength and tolerance of the respiratory muscles are increased, the inspiratory muscles are trained, the problems of dyspnea and the like are solved, the cardiopulmonary function is improved, and the efficiency of movement is further improved. And for expiratory training: human expiration is because of the big excess atmospheric pressure of intrapulmonary pressure, expiration during normal time can not produce the shrink of muscle, when the human body exhales hard, intercostal muscle and abdominal muscle begin to shrink, the intrapulmonary pressure increases to the biggest, internal carbon dioxide can exhale in a large number, adopt physics nature to vibrate the principle, through vibrating the pine take off the adhesion, gather the sputum on the respiratory tract wall, with sputum guide way throat borrow the sputum again and spit out by the cough, so the strength and the tolerance of expiration muscle are improved in the expiration training, strengthen vital capacity, help maintains good health status, be equipped with the air flue and vibrate the mechanism, the effect that has pine phlegm and sputum discharging.

The existing mainstream breathing training device only has one breathing or inhaling training mode, and cannot realize the independent inspiration training or expiration training on one device, or the structure of inspiration training or expiration training is put on a trainer, and the parts for the two types of training are different, so that the structure of the trainer is complex and the operation is inconvenient, for example, the utility model with patent number 201820698786.2, named as a new breathing training device, the utility model discloses a training device, which comprises a training device main body, an air suction joint and a connecting hose, wherein the lower side of the front of the training device main body is provided with an air suction branch port which is extended forwards, one end of the air suction joint is a round port end, the other end of the air suction joint is a mouthpiece, the air suction branch port and the round port end are respectively spliced with the two ends of the connecting hose, the middle part of the connecting hose is provided with a stretchable corrugated section, it can only perform traditional breathing training and cannot perform inspiration training and expiration training separately. There are also training devices in the market, in which the structure of inspiration training or expiration training is integrated into one training device, such as the invention patent with patent number 2015103491813, named breathing training device, which includes a bottle body for inspiration training and an insufflation assembly for insufflation training, both of which are different, resulting in complex structure and high cost of the training device, too many positions to be concerned by the patient when in use, and inconvenient operation.
