【摘要】：心臟病一直是危害人類自身健康的頭號大敵,目前臨床上心音的聽診是預(yù)防此類疾病的重要手段。健康是生命之本,體檢是早期發(fā)現(xiàn)這些疾病的有效措施,因而每一階段的健康體檢就成為預(yù)防此類疾病的手段�，F(xiàn)如今醫(yī)院還沒有針對心音的完備診斷體系;傳統(tǒng)心音聽診在臨床聽診教學中,效率低下且加重病者痛苦;長時間聽診會造成醫(yī)生疲勞,而且由于每個醫(yī)生的主觀因素存在,可能造成誤判斷;傳統(tǒng)的心音聽診不能實時顯示波形圖,也不能多人聽診。因此人們對心音聽診要求越來越高,更加迅速、準確和方便的聽診成為了研究主流。針對這些不足,本論文分為四部分來研究,第一部分是對心音的采集,通過放大濾波電路將人體的生物信號轉(zhuǎn)化成電信號。第二部分是將模擬量數(shù)字化,本論文使用MSP430F149自帶的AD轉(zhuǎn)換,操作方便。第三部分主要是傳輸數(shù)字信號,本論文使用WI-FI模塊RM04將數(shù)據(jù)無線傳送給上位機。第四部分是網(wǎng)站設(shè)計,上位機將接收到的數(shù)字信號通過軟件編程轉(zhuǎn)換成心音圖,更加直觀,同時用戶可以通過智能手機或者個人電腦訪問服務(wù)器來了解自身的健康情況。本論文研究解決了心音不能同時聽診,聽診同時不能顯示心音圖的問題,用戶可以通過網(wǎng)絡(luò)訪問服務(wù)器的方式獲知自身健康情況,本設(shè)計簡化了體檢流程,優(yōu)化了醫(yī)院資源。實驗結(jié)果表明,硬件濾波后第一第二音心音明顯,上位機可以顯示心音波形,用戶可以訪問網(wǎng)站獲知信息,系統(tǒng)工作穩(wěn)定,達到了設(shè)計預(yù)期,有一定的市場前景。
[Abstract]:Heart disease has always been the number one enemy of human health. At present, auscultation of heart sounds is an important means to prevent this disease. Health is the foundation of life and physical examination is an effective measure to detect these diseases early. Nowadays, hospitals do not have a complete diagnostic system for heart sounds; in clinical auscultation teaching, traditional heart-tone auscultation is inefficient and increases the suffering of the seriously ill; prolonged auscultation can cause doctors' fatigue, and because of the subjective factors of each doctor, Traditional heart-tone auscultation can not display waveforms in real time, nor can multiplayer auscultation. Therefore, people have higher and higher requirements for cardiac sound auscultation, more rapid, accurate and convenient auscultation has become the mainstream of research. This paper is divided into four parts. The first part is the acquisition of heart sound, which converts the biological signal of human body into electrical signal by amplifying and filtering circuit. The second part is to digitize the analog quantity. This paper uses AD conversion of MSP430F149, which is easy to operate. The third part is to transmit digital signal. This paper uses WI-FI module RM04 to transmit data wirelessly to the host computer. The fourth part is the website design, the host computer will receive the digital signal through the software programming to convert into the heart sound chart, at the same time, the user can access the server through the smart phone or the personal computer to understand own health condition. This paper solves the problem that heart sounds can not be auscultation at the same time, auscultation can not display heart sounds at the same time, users can access the server through the network to know their own health situation. This design simplifies the process of physical examination and optimizes hospital resources. The experimental results show that the first and second tone heart sound is obvious after the hardware filtering, the upper computer can display the heart sound waveform, the user can visit the website to get the information, the system works stably, achieves the design expectation, and has a certain market prospect.
