Description

A breathing training system based on nasal mask

technical field

The utility model relates to the medical field, in particular to a breathing training system based on a nasal mask.

Background technique

Clinically, patients with respiratory system diseases often suffer from decreased lung function, manifested as a series of symptoms such as decreased respiratory muscle strength, dyspnea, shortness of breath and shortness of breath, which in turn affects the ability of speech production. Compared with the quiet breathing state, the speaking state increases the ventilation requirements. Patients with poor lung function, such as patients with chronic obstructive pulmonary disease, may abnormally change the continuity of speech, intonation and rhythm control, resulting in weak speech and lower volume. In addition, Speaking is also more likely to cause fatigue and cough and asthma than normal people. Long-term delay of the disease will affect the enthusiasm of patients to communicate with others, resulting in a decline in the quality of life. For long-term critically ill bedridden patients, the reduction of verbal communication leads to less work to mobilize the respiratory muscles, resulting in decreased pulmonary function disuse. Therefore, in the rehabilitation of patients with respiratory dysfunction, in addition to training the respiratory muscle strength and improving the breathing pattern, breathing training for speech should also be added to comprehensively improve the rehabilitation effect.

Clinically, the single breath count test (SBCT) is a rapid pulmonary function assessment method. The single breath count test has a good correlation with standard pulmonary function indicators. The correlation coefficient reported in the literature and the FEV1 of lung disease population reaches 0.68 to 0.75. , the single breath count test is to evaluate the lung function through pronunciation, and it also shows the importance of the ability of speech vocalization in the performance of lung function. This test requires the patient to take a deep breath as hard as possible, then count out the numbers continuously at a consciously comfortable volume, at a rhythm of 120 beats per minute, and count the numbers as long as possible in one breath. The longer the number, the better the lung function. the better. The single breath counting method test requires patients to try their best to inhale and expel gas to the greatest extent. However, cognitive differences between different populations, individual subjective enthusiasm, or active adjustment strategies of the larynx may affect the stability of the single breath count test results. These subjective factors are important reasons for affecting the authenticity of the test results. and pronunciation can be quantified in real time, which can reduce the measurement error caused by subjective factors.

Breathing training is an important part of pulmonary rehabilitation, but at present, breathing training is mainly aimed at the decrease of respiratory muscle strength and the change of breathing pattern, which is training without vocalization. In view of the fact that speech is an important function of the human body and is closely related to the level of lung function, adding this training content to the respiratory training system will bring more comprehensive benefits to the patient's respiratory function. At present, the relevant voice training is mainly in the field of music. Vocal training can increase the singer's lung capacity, exercise the ability to control the airflow in and out, and make the voice more loud and pleasing. However, for patients with reduced lung function, language communication has been limited, and there is still a lack of voice training equipment for clinical pulmonary rehabilitation patients.

Therefore, it is necessary to design a voice breathing training device for clinical patients' disease characteristics to increase the content of pulmonary function rehabilitation training, and if the gas inhalation volume and pronunciation volume can be fed back in real time during the training process, it can be more accurately evaluated and guided. train.
