利用正负压研制肺部疾病治疗仪器的探讨

利用气泵的工作原理 ,以及自动阀门的作用 ,按人体肺活动的规律 ,通过泵内活塞运动 ,在管道的引导下 ,向气管、支气管、肺泡内壁施加正压和负压 ,达到吸出气管、支气管、肺泡内的分泌物等异物 ,并用正向压力加快对肺泡的供氧 ,进而达到治疗呼吸道疾病的目的。由于条件和设备能力的限制 ,未作实际试验 ,因此 ,只能作为一种理论性参考

Development of Pneumotherapeutic Apparatus Based on Positive and Negative Pressure

We designed a pneumotherapeutic apparatus based on the principle of air pump, the function of autovalve and the rules of human pulmonary activities. This apparatus, through piston action in the pump guided by several tubes, can exert either positive or negative pressure on the inner walls of trachea, bronchi and alveoli to suck out secretions or other foreign bodies from the trachea, bronchi and alveoli. It can also give a quicker supply of oxygen to the alveoli under positive pressure, In this way, respiratory diseases can be treated. Because of the limited equipment and condition, we haven't made any practical experiments so far. Therefore the discussion is for theoretical reference only.
