Description

Respiratory muscle training machine

technical field

The invention relates to the technical field of respiratory training equipment, in particular to a respiratory muscle training machine.

Background technique

Chronic obstructive pulmonary disease (COPD) is a common chronic bronchitis and/or emphysema characterized by persistent airflow limitation, which can further develop into a common chronic disease of pulmonary heart disease and respiratory failure. It is related to the abnormal inflammatory response of harmful gases and particles, and the disability rate and mortality rate are very high. The global incidence rate of over 40 years old has reached as high as 9% to 10%. Common symptoms of COPD are: cough, expectoration, shortness of breath or difficulty breathing (labored breathing). This is a chronic lung disease that can only be alleviated, not reversed. Common treatments include: smoking cessation, prevention of lung infection, breathing exercises, oxygen inhalation, and medication.

Physical therapy for COPO usually includes respiratory muscle training, vibration and expectoration, which can improve dyspnea and prevent infection caused by airway blockage. Holding up the resistance ball can be used as a load during the breathing period, and roughly judge the expiratory flow rate and expiratory volume. The advantage of this device is that it has a simple structure and the effect of exhalation training is obvious. The disadvantage is that the load is constant and cannot be changed according to the patient's condition.

The common vibrating expectorant machine is that through the pulse air pressure, the impact force generated by the sudden expansion of the air bag hits the patient's back, vibrates the chest cavity, separates the mucus in the airway, and discharges the sputum. Elderly and infirm patients.

Existing respiratory muscle training and vibration expectoration are both treated with independent equipment. During treatment, the load of exhalation training cannot be changed according to the patient's condition, and the impact of external equipment on the patient's vibration is relatively large, which is easy to cause Patient discomfort.
