Research On Some Key Technologies Of A Systematic For Synthetical Measurement Of Chinese Medical Massage

Massage is an important kind of non-drug treatments and has notable curative effect on many diseases. It is a therapy that doctor operates on the patient by manipulation, with mechanical stimulations to regulate the body’s physiology and pathology, ultimately achieve the effects of dredging meridian, activating blood and resolving blood-stasis, relaxing muscles and tendons, eliminating pathogens and strengthening vital qi. So far there is no such kind of equipments capable to measure and analyze the effectiveness of massage, which result in the fact that it is difficult to reflect operations of massage and the related biological effect comprehensively and objectively, and it has seriously hindered the development of the research of the mechanism of traditional Chinese medical massage.This dissertation is originated from the National Natural Science Foundation (NO.60672024, NO.61072032) and National High Technology Research and Development Program (863Program NO.2007AA042220). Considering the lack of a platform which can detect the3D forces applied by massage doctors and the correlative physiological parameters detected by the treated area of human body in real-time, this dissertation presents a measuring and analysis method based on holistic biological effect, makes an innovative research on the key problems, such as the correlation between massage operations and biological effect, physical model of the sensor, and decouple of the sensor, etc. And on this basis, develops a measuring and analyzing platform which can detect the3D forces applied by massage doctors in real-time, and synchronously, monitor and record the correlative physiological parameters detected by the treated area of human body.The major study context and innovative results are as follows:1. Aimed at solving the mechanism of traditional Chinese medical massage, a measuring and analysis method based on holistic biological effect is presented by combining Chinese medicine and modern medical theory. A measuring and analyzing platform which consist of two parts, detecting system and analyzing system, is developed that can detect the3D forces applied by massage doctors in real-time, and synchronously, monitor and record the correlative physiological parameters detected by the treated area of human body, lay a foundation for the development of massage mechanism.2. Explores the correlation between massage operations and sEMG. Multi-information sampling system which can detect the force of finger-pressing manipulation and sEMG signals of the sample involved in real time is built. The force and sEMG signals collected by the system are analyzed based on the characteristics of massage operations, and the results indicates that there is a remarkable effect on sEMG by finger-pressing manipulation.3. Based on the ideal characteristics of pressure-sensitive conductive rubber, the overall physical model of the3-D force flexible array sensor is proposed, and applied a decoupling method based on LM algorithm to simulate. This analysis results can provide theoretical basis for the structure design and force information extraction of3-D flexible array sensor based on conductive rubber.4. According to the massage forces detecting requirements, a new kind of3-D force flexible array sensor is developed, which is thinner and more flexible. And a simplified model of the sensor is established combined with part of the sensitive material’s actual characteristics, and the complicated coupling problems are solved by the model, and can further satisfy the demands to the massage forces detecting.5. Based on the conductive rubber’s actual force conditions and the sensor’s internal structure, the relationship between the resistance and strain of conductive rubber is analyzed in depth, then weakening the hypothesis in the past research, revising the simplified model, and a physical model of a3D force excitation and output resistances of the sensor is employed, by which the sensing mechanism of the3D flexible tactile sensor array based on pressure-sensitive conductive rubber is explored in more detail. The structure of the sensor is optimized according to the simulation results. More operational factors based on the sensitive material’s actual characteristics are taken into account in the model, which can provided theory support for the development of the mechanical quantities comprehensive detection cushion for the massage acting forces measurement.
