【摘要】：隨著醫(yī)療水平的提高，人類的健康問(wèn)題開(kāi)始成為了社會(huì)關(guān)注的重點(diǎn)，與此同時(shí)，隨著工作、生活、學(xué)習(xí)等壓力的增加，飲食結(jié)構(gòu)的改變，使得各種疾病的患病率逐年遞增，，并且呈現(xiàn)出低齡化的態(tài)勢(shì)，而這些疾病的發(fā)病基礎(chǔ)都是和微循環(huán)障礙有關(guān)。目前，對(duì)微循環(huán)的檢查大多應(yīng)用在臨床檢查中，如何在社區(qū)醫(yī)療和家庭保健中建立一種簡(jiǎn)便、可靠的微循環(huán)檢查技術(shù)開(kāi)始受到人們的關(guān)注。 本文在現(xiàn)有研究基礎(chǔ)上，通過(guò)對(duì)不同年齡段人群的指端容積脈搏波信號(hào)進(jìn)行分析，并結(jié)合多個(gè)特征參數(shù)對(duì)微循環(huán)功能狀態(tài)進(jìn)行評(píng)估，從而為社區(qū)醫(yī)療、家庭保健中提供了一種方法簡(jiǎn)便，可信度較大的微循環(huán)功能檢測(cè)方法。 本文首先針對(duì)國(guó)內(nèi)外微循環(huán)功能檢查的研究現(xiàn)狀闡述了微循環(huán)與各種疾病之間的關(guān)系，指出研究微循環(huán)功能狀態(tài)對(duì)人體健康的重要意義。 其次，研究了容積脈搏波與微循環(huán)狀態(tài)之間的關(guān)系，通過(guò)對(duì)容積脈搏波波形特征的分析，闡述了特征點(diǎn)與人體生理、病理狀態(tài)以及微循環(huán)狀態(tài)之間的關(guān)系。 然后，設(shè)計(jì)了一套基于STM32的容積脈搏波采集系統(tǒng)，該系統(tǒng)主要可以完成容積脈搏波的數(shù)據(jù)采集，波形及參數(shù)實(shí)時(shí)顯示以及串口通信等功能。容積脈搏波采集系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)為之后采集數(shù)據(jù)提供了保障。 最后，介紹了容積脈搏波的信號(hào)特點(diǎn)，針對(duì)其特點(diǎn)采用改進(jìn)后的小波閾值函數(shù)對(duì)信號(hào)進(jìn)行預(yù)處理，然后分別對(duì)兩組不同年齡段人群的容積脈搏波信號(hào)提取時(shí)域和頻域的特征值，通過(guò)對(duì)比分析，得出了可以作為本系統(tǒng)中評(píng)價(jià)微循環(huán)狀態(tài)的特征參數(shù)。
[Abstract]:With the improvement of medical treatment, human health has become the focus of social attention. At the same time, with the increasing pressure of work, life and study, and the change of diet structure, the prevalence rate of various diseases increases year by year. And present a trend of younger age, and these diseases are based on microcirculation disorders. At present, the examination of microcirculation is mostly used in clinical examination. How to establish a simple and reliable microcirculatory examination technology in community medicine and family health care has been paid more and more attention. On the basis of existing research, this paper analyzes the pulse wave signal of finger volume in different age groups, and evaluates the function of microcirculation in combination with several characteristic parameters, so that it can be used for community medical treatment. A simple and reliable method for detecting microcirculation function is provided in family health care. In this paper, the relationship between microcirculation and various diseases is discussed, and the significance of studying the state of microcirculation function for human health is pointed out. Secondly, the relationship between the volume pulse wave and the microcirculation state is studied. By analyzing the characteristics of the volume pulse wave, the relationship between the characteristic points and the physiological, pathological and microcirculatory state of the human body is expounded. Then, a set of volumetric pulse wave acquisition system based on STM32 is designed. The system can accomplish the functions of data acquisition, real-time display of waveform and parameters, serial communication and so on. The design and implementation of the volumetric pulse wave acquisition system provide a guarantee for the later data acquisition. Finally, the signal characteristics of volume pulse wave are introduced. The improved wavelet threshold function is used to preprocess the signal, and then the characteristic values of time domain and frequency domain are extracted from the volume pulse wave signal of two groups of different age groups. Through comparative analysis, the characteristic parameters can be used to evaluate the state of microcirculation in this system.
