一种气射流型中医按压方法与仪器

A Kind of jet Airstream Pressing Method and Machine of Traditional Chinese Medicine

本文介绍一种根据中医推拿的按压手法研制的气射流按压仪 ,通过控制气压的大小和气射流脉冲频率来模拟按压手法。在对人体手部穴位的试验中我们发现 ,无论控制多少气压值 ,在离喷口一定距离处能感受的力最大 ,此段距离应该是仪器对穴位进行治疗的最佳距离。

A kind of jet aistream pressing machine is introduced in this paper according to the pressing techniqu of the naprapathy in Traditinoal Chinese Medicine.The pressing technique could be simulated by controlling the magnitude of the air pressure and the frequency of the impulsive jet airstream.When the jet airstream impinged on the acupunctural point of the hand,the patient felt the greatest force at some distance from the jet nozzle at different magnitude of the air pressure.We supposed this distance was the most optimunm distance at which the machine can be applied on the acupoint.Then we explained the phenomenon and also confrimed the distance by more accurate experiments and the engineering computational method of the axially symmetrical subsonic isothermal free jet airstream.
