【摘要】：中藥在醫(yī)治航天載人、航空飛行和航海訓(xùn)練等所產(chǎn)生的眩暈病具有獨(dú)特的療效,如對(duì)人中樞認(rèn)知無(wú)毒副作用;增強(qiáng)體質(zhì)和肌體抗運(yùn)動(dòng)病能力;保持肌體在復(fù)雜環(huán)境下正常操作功能等。隨著抗運(yùn)動(dòng)病中藥研究的加快,抗眩暈中藥療效的科學(xué)監(jiān)測(cè)、分析和評(píng)價(jià)成為中藥現(xiàn)代化亟待解決的關(guān)鍵問(wèn)題之一。目前,中藥療效的評(píng)價(jià)大多是沿襲了西藥的分析方法,以分析中藥的化學(xué)成分為主。但是由于中藥化學(xué)成分復(fù)雜性,各種成分相互影響、彌補(bǔ),其通過(guò)多種途徑、靶點(diǎn)發(fā)揮物質(zhì)群的整體作用,化學(xué)成分分析很難準(zhǔn)確的評(píng)價(jià)藥效。 本文從事的研究是陜西省科技計(jì)劃課題(抗運(yùn)動(dòng)病中藥藥效數(shù)字化評(píng)價(jià)新方法研究)的部分內(nèi)容,研究成果將對(duì)探討中藥藥效檢測(cè)方法的現(xiàn)代化,以及航天、航空和航海中的眩暈病防治具有重要的理論意義和應(yīng)用前景。 本文針對(duì)目前對(duì)大白鼠在眩暈狀態(tài)下眼震和血流量進(jìn)行檢測(cè)的各種方法中存在的不足,提出了一種基于數(shù)字化的眼震和血流量無(wú)創(chuàng)傷檢測(cè)的新方法;在研究血流量傳感器的基礎(chǔ)上,根據(jù)多普勒原理和課題研究的要求,設(shè)計(jì)了一種適用血流量檢測(cè)的新型皮膚光纖血流量傳感器,實(shí)現(xiàn)了對(duì)大白鼠耳部血流量信號(hào)的無(wú)創(chuàng)傷檢測(cè);根據(jù)實(shí)驗(yàn)血流量檢測(cè)的特點(diǎn)和數(shù)據(jù)通信的需求,在比較各種無(wú)線通信的特點(diǎn)后,采用nRF2401無(wú)線收發(fā)芯片、單片機(jī)和計(jì)算機(jī)串口,實(shí)現(xiàn)了血流量信號(hào)從傳感器到主控計(jì)算機(jī)的信號(hào)通信;分析了傳統(tǒng)眼震檢測(cè)方法和測(cè)量?jī)x器的主要缺陷,采用CCD傳感器采集大白鼠眼震的模擬圖像信號(hào),通過(guò)模擬圖像信號(hào)無(wú)線傳輸模塊和視頻采集卡把圖像信號(hào)傳輸?shù)接?jì)算機(jī),由計(jì)算機(jī)對(duì)圖像信號(hào)進(jìn)行分析和處理,實(shí)現(xiàn)了眼震圖像的實(shí)時(shí)采集和分析;最后,研究了在室內(nèi)環(huán)境下進(jìn)行血流量和眼震動(dòng)態(tài)檢測(cè)的方法,選擇VC++6.0為開(kāi)發(fā)工具,研發(fā)了以RS-232接口通信、圖像獲取、眼震圖像分析處理和數(shù)據(jù)分析顯示等為主的系統(tǒng)軟件。 實(shí)驗(yàn)結(jié)果表明,本文設(shè)計(jì)的數(shù)據(jù)采集和通信系統(tǒng)硬件部分工作穩(wěn)定,體積小,具有較強(qiáng)的抗干擾能力;軟件設(shè)計(jì)部分界面友好,操作方便,處理速度快,能夠?qū)崿F(xiàn)實(shí)時(shí)分析和處理。 本文研究?jī)?nèi)容是陜西省科技計(jì)劃課題(2005K16-G7(4))和航空科學(xué)基金課題(04I53068)資助項(xiàng)目。
[Abstract]:Chinese medicine has a unique curative effect in treating vertigo caused by spaceflight manned flight and navigation training such as no toxic and side effects to human central cognition; Enhancing physique and the ability of body to resist motion sickness; With the rapid development of traditional Chinese medicine research on anti-motion sickness, scientific monitoring of the curative effect of anti-vertigo medicine was carried out. Analysis and evaluation has become one of the key problems to be solved in the modernization of traditional Chinese medicine. At present, the evaluation of curative effect of traditional Chinese medicine is mostly based on the analysis method of western medicine. But because of the complexity of the chemical composition of traditional Chinese medicine, various components influence each other, make up for it, through many ways, the target play the overall role of the group of substances. Analysis of chemical components is difficult to accurately evaluate the efficacy of the drug. The research in this paper is part of Shaanxi province science and technology project (research on new method of digital evaluation of Chinese herbal medicine efficacy of anti-sports disease). The research results will explore the modernization of traditional Chinese medicine efficacy detection method. And the prevention and cure of vertigo in aerospace, aviation and navigation have important theoretical significance and application prospect. In this paper, a new method based on digitization for the detection of nystagmus and blood flow without trauma in rats under vertigo was put forward in view of the shortcomings of various methods for the detection of nystagmus and blood flow under vertigo. Based on the research of blood flow sensor, according to the Doppler principle and research requirements, a new skin fiber blood flow sensor is designed for blood flow detection. The non-invasive detection of the blood flow signal in the ear of rats was realized. According to the characteristics of experimental blood flow detection and the demand of data communication, after comparing the characteristics of various wireless communications, nRF2401 wireless transceiver chip, single-chip microcomputer and computer serial port are adopted. The signal communication of blood flow signal from sensor to master computer is realized. The main defects of traditional nystagmus detection methods and measuring instruments were analyzed. The analog image signals of rat nystagmus were collected by CCD sensor. Through the wireless transmission module of analog image signal and the video acquisition card, the image signal is transmitted to the computer, the image signal is analyzed and processed by the computer, and the real-time acquisition and analysis of the nystagmus image is realized. Finally, the method of blood flow and nystagmus dynamic detection in indoor environment is studied. VC 6.0 is selected as the development tool, and the RS-232 interface communication and image acquisition are developed. Nystagmus image analysis processing and data analysis and display system software. The experimental results show that the hardware part of the data acquisition and communication system designed in this paper works stably, has small volume and has strong anti-interference ability. The interface of the software design is friendly, the operation is convenient, the processing speed is fast, and the real-time analysis and processing can be realized.
