【摘要】：在大多数血液循环系统理论当中,动脉被看作是血液流动的管道,但是在实际的人体生理系统中,心脏仅仅用了1.7瓦的输出功率,面对着动脉系统的复杂结构,克服了动脉管道的层层阻力,并将血液输送到身体的每一个角落。如果把动脉血管当作是血液流动的管道,这种输送效率是没有办法达到的。因为在动脉系统的能量分配当中,由动脉管壁振动所储存的弹性势能占了98%,远远超过血液本身流动的动能,因此共振理论把动脉系统看作是血液压力波的传递系统,心脏将血液泵出后,撞击在主动弓脉的弯曲上,用来增大血液压力波的振幅；这个血液压力波在经过动脉系统传送到末端之后,再通过末端的毛细血管床的小开口,将血液推送到毛细血管,完成供血的任务；各器官通过与心脏的跳动达到良好的共振,从而大幅度地提高动脉系统血液输送的效率。通过这个理论,循环系统的高输送效率才能得到解释。脉搏波的频域分析为脉搏波的研究提供了新的思路。在频域分析方面,基于血液循环径向共振理论,证实了传统医学脉诊诊断的真实性和科学基础,使得脉搏波的谐波分析方法有了理论上的意义,并在一系列的实验研究中取得了进展。本文的主要内容有： 1)、动脉系统血液循环原理的研究。分别分析了西方医学在血液循环理论上的瓶颈,中国传统医学在循环系统上面独到的见解,以及基于血液循环径向共振理论的脉搏谐波分析的新方法。 2)、流量理论与共振理论的推导和比较。分析了弹性贮器模型,泊肃叶方程,莫恩斯-柯特维格方程,沃姆斯莱数方程的不足之处,进而研究了径向共振理论的推导过程和理论解,表明共振理论更符合实际的心血管系统生理学构造。 3)、设计和实现了人体脉搏信号采集和处理系统。完成了系统的硬件设计和软件开发。系统硬件包括脉搏传感器,信号调理,模数转换,USB通信等。软件基于Labview平台开发。采用小波变换的方法,达到了去除脉搏波当中噪声的目的。 4)、禁食对人体脉搏波各次谐波的影响实验研究。本实验通过分析人体在禁食条件下和恢复饮食条件下的桡动脉脉搏的各次谐波幅度变化,来研究人体对禁食情况下的生理反应。实验结果表明,在人体持续禁食的过程当中,脉搏波各次谐波确实会发生相关的变化：桡动脉脉搏波的二次谐波的幅值在禁食的情况下显著增加,而六次谐波的幅值在禁食的情况下显著下降。而随着恢复饮食,桡动脉脉搏波的二次谐波和六次谐波都逐渐恢复到原有水平。根据血液循环的共振理论,谐波的幅值跟血液分配的比例有关,这些结果显示,在禁食情况下,人体有一个重新分配血液的趋势,来调整人体各个组织和器官的能量分配。进一步证实了传统医学脉诊诊断的真实性和科学基础。
[Abstract]:In most circulatory system theories, the artery is regarded as a conduit for blood flow, but in the actual human physiological system, the heart uses only 1.7 watts of output power, facing the complex structure of the artery system. It overcomes the resistance of the arterial conduit and sends blood to every corner of the body. If the arterial vessel is regarded as the blood flow pipeline, the efficiency of this transport can not be achieved. Because in the energy distribution of the arterial system, the elastic potential energy stored by the vibration of the arterial wall accounts for 98%, which far exceeds the kinetic energy of the blood flow itself, so the resonance theory regards the arterial system as the transmission system of the blood pressure wave. The heart pumps out the blood and hits it on the bend of the active arch to increase the amplitude of the blood pressure wave, which passes through the arterial system to the end and then through the small opening of the capillary bed at the end. Push the blood to the capillaries to complete the task of supplying blood; each organ has a good resonance with the beating of the heart, which greatly improves the efficiency of blood delivery in the arterial system. The high transport efficiency of the circulatory system can be explained. The frequency domain analysis of pulse wave provides a new way for the study of pulse wave. In frequency domain analysis, based on the theory of radial resonance of blood circulation, the authenticity and scientific basis of traditional medical pulse diagnosis are confirmed. The harmonic analysis method of pulse wave has theoretical significance, and has made progress in a series of experiments. The main contents of this paper are as follows:. 1. A study on the principle of blood circulation in the arterial system. The theoretical bottleneck of blood circulation in western medicine was analyzed, and the unique views of Chinese traditional medicine on the circulation system were analyzed. And a new method of pulse harmonic analysis based on radial resonance theory of blood circulation. (2) the derivation and comparison of flow theory and resonance theory. The inadequacies of elastic receptacle model, Poiseuer equation, Moens-Cottevig equation, Warmsley number equation are analyzed. Furthermore, the derivation process and the theoretical solution of the radial resonance theory are studied. It is shown that the resonance theory is more suitable for the physiological structure of the cardiovascular system. 3The system of human pulse signal acquisition and processing is designed and implemented. The hardware design and software development of the system are completed. The hardware of the system includes pulse sensor, signal conditioning, The software is based on Labview platform. Wavelet transform is used to remove the noise in pulse wave. Experimental study on the effect of fasting on every harmonics of human pulse wave. This experiment analyzed the changes of the amplitude of harmonics of radial artery pulse in human body under fasting condition and recovery diet condition. To study the physiological response of the human body to fasting. The results show that during the course of a sustained fasting, The amplitude of the second harmonic of the pulse wave of the radial artery increases significantly in the case of fasting, while the amplitude of the sixth harmonic decreases significantly in the case of fasting. The second harmonic and sixth harmonic of radial pulse wave are gradually returning to the original level. According to the resonance theory of blood circulation, the amplitude of harmonic wave is related to the proportion of blood distribution. These results show that in the case of fasting, The human body has a tendency to redistribute blood to regulate the energy distribution of various tissues and organs of the human body, which further confirms the authenticity and scientific basis of traditional medical pulse diagnosis.
