Development of Self Training Device for Lung Function Compliance Guided by Meridians

Objective To develop a self deep breathing training device which can improve lung function compliance and blood oxygen saturation. Methods The device consists of four parts:flow tube, measuring cylinder, mobile phone holder and meridian guidance audio-visual synthesis training software. The flow tube measures the flow rate of inhaled gas, the metering cylinder measures the total amount of inhaled gas, and the mobile phone rack is equipped with a mobile phone storing the meridian guidance audio-visual synthesis training software. Results The device is reasonable in structure and flexible in operation, which can meet the requirements of self deep inspiration training under the guidance of training module. Conclusion Deep inspiration training under the guidance of guidance training module can form "deep and slow" abdominal breathing, and then improve lung function.
