Background

With the development of industrialization progress and the acceleration of the production pace of social life, various air pollution is gradually aggravated, and the health problem of lung function is invading the life of people. The respiratory training device is a novel physiotherapy auxiliary instrument for respiratory muscle training and is used for improving the ventilation mode caused by shallow breathing, so as to promote lung expansion and increase lung capacity. The enhanced respiratory muscle training by the respiratory training device is also widely used clinically, and a patient with pulmonary diseases can improve pulmonary ventilation by using the respiratory training device, so that the efficiency of single respiration is improved, and the activity endurance is increased.

The respiratory training device mainly enables a user to overcome the resistance of the trainer in the respiratory process by setting different resistances, so as to achieve the purpose of training the heart and lung functions. There are 3 common resistance adjustment schemes in current breath-training devices: spring resistance, magnetic attraction resistance and air resistance. The spring resistance is applied to the spring in the breathing and sucking process, so that an airway passage is opened to breathe and suck, the scheme has wide resistance adjustment range, stepless resistance adjustment can be realized by matching with a sensor, but the spring resistance is limited by the attribute of the spring, the appearance and the weight of the product can be influenced, and a single spring can only realize a single function; the magnetic resistance is controlled by adjusting the magnetic resistance, the scheme has low requirements on external design, and can simultaneously perform respiratory training, and support stepless adjustment of the resistance, but the technical aspect is still immature; the air resistance is the size of adjusting the ventilation pore area in expiration and inspiration in-process, and then forms air current resistance, and this scheme is low to structure and design requirement, can breathe the training simultaneously, has obtained wide application.

Most of the common respiratory training devices at present are provided with only one of an expiration channel and an inspiration channel, and the expiration and inspiration processes can not be completed simultaneously in the training process, so that the ventilation process of a user is inconvenient, and the function is single; most common respiratory training devices are manually adjusted for resistance, and are required to be operated by two hands, so that users are inconvenient to use.

In summary, how to solve the problems of inconvenient ventilation process, single function and inconvenient use of the existing respiratory training device is a problem to be solved by those skilled in the art.
