一种肺功能锻炼瓶的设计与应用

Design and application of a pulmonary function exercise bottle

慢性阻塞性肺疾病(COPD)是一种以气道阻塞为主要特征的严重呼吸道疾病,具有发病率高、病死率高等特点。康复锻炼可以减少患者病情反复加重,对改善肺功能、提高生活质量有积极作用。但现有的肺功能康复训练方法仍存在诸多不足,为此我们设计了一种能根据患者需求进行压力调节的肺功能锻炼瓶,操作简单,易于掌握。该锻炼瓶主要由瓶体、螺纹圆形盖和吹气管3部分组成。瓶体为长方体结构,用于容纳液体,上方设有加液口;加液口外侧设有一个螺纹圆形盖,可根据患者的耐受程度进行压力调节,以使训练强度逐渐增加,从而提高训练效果;吹气管可插入瓶体内,患者通过吹气管进行吹气。与传统的康复训练相比,应用新型肺功能锻炼瓶进行康复训练时,瓶内的气压可调节,适用范围更广,成本较低,且使用方便。为临床和居家康复提供了一种很好的解决方案,值得推广使用。

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.
