Research On Acupuncture Manipulation Quantitative Theory And Design Of Acquisition System

Acupuncture manipulation is the method that is acupuncture needles operate acupoints from needle insertion to needle extraction. Although the efficacy of acupuncture techniques have already been widely recognized at home and abroad, traditional Chinese medicine,including acupuncture, making judgments is based on an experience, Under this experience of understanding, the efficacy of acupuncture treatment depend on physician understanding for acupuncture and level of skilled use of acupuncture manipulation. If using some quantities express the leading experts' acupuncture, guiding medical treatment and learning,will help the inheritance and development of acupuncture.This article select two acupuncture manipulation:rotating,lifting and thrusting, completing collection system base on TMS320VC5509A and and the acupuncture manipulation collected quantitative research. it include the following four aspects:1.Analysis of a variety of commonly used acupoints acupuncture manipulation of the generated forces, introducing materials and production process of rotating,lifting and thrusting sensors in detail, this sensor is not only small size, light weight, but also collected between the two signals don't interfere with each other.2.Completed the hardware design:According to the characteristics of the collected signal,produced a signal conditioning circuit and A/D converter; meanwhile, in order to ensure the system normally work and DSP communication with the host computer, designde the DSP minimum system circuit and the program expanded circuit, the serial communication circuit.3. Completed the software design, including the AD conversion program, adaptive filtering program, serial communications program; and PC software design, including serial communication procedures, real-time display procedures, data storage procedures.4. Quantitative research of acupuncture manipulation:analysed the collected waveforms in the frequency domain; used Burg algorithm for identify the power spectral density of acupuncture manipulation AR model parameters. To validate possibility of parameter which figure acupuncture manipulation,used the power spectral density the AR model parameters as input, BP neural network as classifier obtained nicer result,, validated this parameter is valid;laid the foundation for further study. The next work is to further improve the system, increase system function, measuring more force; selecting more acupuncture manipulation quantitative.
