Development of Automatic Manipulation Device for Acupuncture (AMDA).

Needle lifting and thrusting manipulation is one of common skills in acupuncture. However, there exists artificial error in frequency and amplitude due to individual difference when performing lifting and thrusting during acupuncture. For providing stable and quantified effects and higher frequency when doing lifting and thrusting manipulation, a well controlled device is needed. The aim of this article is to report the preliminary results of the development of Auto Manipulation Device for Acupuncture (AMDA) and characterization of its functional parameters. A tissue-simulating Agar gel phantom with 4.8%, 5.2%, and 5.4% concentrations was prepared and used for characterization of the AMDA. Tests of the linearity, reliability and safety of the AMDA were implemented with conditions of different drive voltages, frequencies, and simulated tissues. Our preliminary results have demonstrated the developed AMDA its plausibility in the clinical application of acupuncture.
