Design and application of a pulmonary function exercise bottle

Abstract

Chronic obstructive pulmonary disease (COPD) is a severe respiratory disease characterized by airway obstruction with high mortality and rate of recurrence. Rehabilitation exercise can lessen the possibility of the progressive exacerbation of the patient's condition, exerting an active role in improving their lung function and the quality of the patients' life. Therefore, we have designed a lung function exercise bottle, which is capable of adjusting the pressure according to the patient's needs. It is easy to operate and apply in practice. The exercise bottle is composed of three components, including bottle body, threaded round cap and air blow pipe. The bottle body is formed in rectangle shape, and utilized to contain liquid. The filling opening is designed on the top of the bottle. Outside of the filling opening, there is a screw thread round cap, which can adjust the pressure according to the patient's tolerance, gradually increasing the training intensity,and improving the training effect thereby. The blowpipe can be inserted into the bottle body and the patient can blow the air through the tube. Compared with the traditional rehabilitation training, when the newly invented lung function exercise bottle has been used for rehabilitation exercise, the air pressure in the bottle can be adjusted, with the advantage of wider range of application, lower cost and more convenient. It provides a good solution for clinical and home-based rehabilitation and is worth of popularizing.
