【摘要】：在大多數(shù)血液循環(huán)系統(tǒng)理論當(dāng)中,動(dòng)脈被看作是血液流動(dòng)的管道,但是在實(shí)際的人體生理系統(tǒng)中,心臟僅僅用了1.7瓦的輸出功率,面對(duì)著動(dòng)脈系統(tǒng)的復(fù)雜結(jié)構(gòu),克服了動(dòng)脈管道的層層阻力,并將血液輸送到身體的每一個(gè)角落。如果把動(dòng)脈血管當(dāng)作是血液流動(dòng)的管道,這種輸送效率是沒有辦法達(dá)到的。 因?yàn)樵趧?dòng)脈系統(tǒng)的能量分配當(dāng)中,由動(dòng)脈管壁振動(dòng)所儲(chǔ)存的彈性勢(shì)能占了98%,遠(yuǎn)遠(yuǎn)超過(guò)血液本身流動(dòng)的動(dòng)能,因此共振理論把動(dòng)脈系統(tǒng)看作是血液壓力波的傳遞系統(tǒng),心臟將血液泵出后,撞擊在主動(dòng)弓脈的彎曲上,用來(lái)增大血液壓力波的振幅；這個(gè)血液壓力波在經(jīng)過(guò)動(dòng)脈系統(tǒng)傳送到末端之后,再通過(guò)末端的毛細(xì)血管床的小開口,將血液推送到毛細(xì)血管,完成供血的任務(wù)；各器官通過(guò)與心臟的跳動(dòng)達(dá)到良好的共振,從而大幅度地提高動(dòng)脈系統(tǒng)血液輸送的效率。通過(guò)這個(gè)理論,循環(huán)系統(tǒng)的高輸送效率才能得到解釋。 脈搏波的頻域分析為脈搏波的研究提供了新的思路。在頻域分析方面,基于血液循環(huán)徑向共振理論,證實(shí)了傳統(tǒng)醫(yī)學(xué)脈診診斷的真實(shí)性和科學(xué)基礎(chǔ),使得脈搏波的諧波分析方法有了理論上的意義,并在一系列的實(shí)驗(yàn)研究中取得了進(jìn)展。 本文的主要內(nèi)容有： 1)、動(dòng)脈系統(tǒng)血液循環(huán)原理的研究。分別分析了西方醫(yī)學(xué)在血液循環(huán)理論上的瓶頸,中國(guó)傳統(tǒng)醫(yī)學(xué)在循環(huán)系統(tǒng)上面獨(dú)到的見解,以及基于血液循環(huán)徑向共振理論的脈搏諧波分析的新方法。 2)、流量理論與共振理論的推導(dǎo)和比較。分析了彈性貯器模型,泊肅葉方程,莫恩斯-柯特維格方程,沃姆斯萊數(shù)方程的不足之處,進(jìn)而研究了徑向共振理論的推導(dǎo)過(guò)程和理論解,表明共振理論更符合實(shí)際的心血管系統(tǒng)生理學(xué)構(gòu)造。 3)、設(shè)計(jì)和實(shí)現(xiàn)了人體脈搏信號(hào)采集和處理系統(tǒng)。完成了系統(tǒng)的硬件設(shè)計(jì)和軟件開發(fā)。系統(tǒng)硬件包括脈搏傳感器,信號(hào)調(diào)理,模數(shù)轉(zhuǎn)換,USB通信等。軟件基于Labview平臺(tái)開發(fā)。采用小波變換的方法,達(dá)到了去除脈搏波當(dāng)中噪聲的目的。 4)、禁食對(duì)人體脈搏波各次諧波的影響實(shí)驗(yàn)研究。本實(shí)驗(yàn)通過(guò)分析人體在禁食條件下和恢復(fù)飲食條件下的橈動(dòng)脈脈搏的各次諧波幅度變化,來(lái)研究人體對(duì)禁食情況下的生理反應(yīng)。實(shí)驗(yàn)結(jié)果表明,在人體持續(xù)禁食的過(guò)程當(dāng)中,脈搏波各次諧波確實(shí)會(huì)發(fā)生相關(guān)的變化：橈動(dòng)脈脈搏波的二次諧波的幅值在禁食的情況下顯著增加,而六次諧波的幅值在禁食的情況下顯著下降。而隨著恢復(fù)飲食,橈動(dòng)脈脈搏波的二次諧波和六次諧波都逐漸恢復(fù)到原有水平。根據(jù)血液循環(huán)的共振理論,諧波的幅值跟血液分配的比例有關(guān),這些結(jié)果顯示,在禁食情況下,人體有一個(gè)重新分配血液的趨勢(shì),來(lái)調(diào)整人體各個(gè)組織和器官的能量分配。進(jìn)一步證實(shí)了傳統(tǒng)醫(yī)學(xué)脈診診斷的真實(shí)性和科學(xué)基礎(chǔ)。
[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.
