【摘要】：輸血是搶救危重病人的一種特殊醫(yī)療措施,但是乳糜血會(huì)增加三高人群患動(dòng)脈硬化等疾病的概率,為此國(guó)家在《全血及成分血質(zhì)量要求》中規(guī)定禁止使用重度乳糜血。目前,定點(diǎn)或移動(dòng)采血站大都采用肉眼觀測(cè)的方法來(lái)判定血漿乳糜度,存在一定的人為誤差。極少數(shù)大型采血站使用大型檢測(cè)儀器如酶標(biāo)儀等判定血漿乳糜度,需要使用昂貴的儀器且不便于攜帶。因此,微型化、低成本、高精度血漿乳糜度檢測(cè)系統(tǒng)成為亟待解決的問(wèn)題。本文針對(duì)傳統(tǒng)血漿乳糜度檢測(cè)方法存在人為誤差大、儀器昂貴、體積龐大等問(wèn)題,利用電荷耦合器件(CCD)靈敏度高及可靠性好等優(yōu)點(diǎn),搭建了一款以CCD (TCD1304)為核心的血漿乳糜度檢測(cè)系統(tǒng)。血漿乳糜度檢測(cè)系統(tǒng)由LED光源、光路系統(tǒng)、光電轉(zhuǎn)換器件以及信號(hào)處理系統(tǒng)等組成。系統(tǒng)選用TCD1304AP作為光電轉(zhuǎn)換器件,使用CPLD為其搭建驅(qū)動(dòng)電路,利用AD9945芯片將CCD采集到的光信號(hào)轉(zhuǎn)換成數(shù)字信號(hào),采用SPI通信將數(shù)字信號(hào)數(shù)據(jù)傳送到ARM9系列S3C2440處理器,并通過(guò)LCD進(jìn)行結(jié)果顯不。利用本文設(shè)計(jì)的血漿乳糜度檢測(cè)系統(tǒng),分別對(duì)不同乳糜度的血漿進(jìn)行標(biāo)定,得出快速血漿乳糜度的判定標(biāo)準(zhǔn),利用該判定標(biāo)準(zhǔn)對(duì)血漿乳糜度進(jìn)行檢測(cè)及判定。實(shí)驗(yàn)結(jié)果表明,該檢測(cè)系統(tǒng)能夠快速準(zhǔn)確的判定出血漿乳糜度,證明本文設(shè)計(jì)的血漿乳糜度檢測(cè)系統(tǒng)具有檢測(cè)準(zhǔn)確率高、快速、便攜等優(yōu)點(diǎn)。
[Abstract]:Blood transfusion is a special medical measure for rescuing critically ill patients, but chylous blood will increase the probability of suffering from arteriosclerosis and other diseases in three high populations. Therefore, the State forbids the use of severe chylous blood in the quality requirements of whole blood and blood components. At present, fixed-point or mobile blood collecting stations mostly use the method of naked eye observation to determine the degree of plasma milk, and there is a certain human error. A few large blood collecting stations use large testing instruments, such as enzyme labeling instrument, to determine the degree of plasma milk. It is necessary to use expensive instruments and is not easy to carry. Therefore, the miniaturized, low cost, high precision plasma milk chylic detection system has become an urgent problem to be solved. In view of the disadvantages of traditional plasma chyle detection methods, such as large human error, expensive instruments and large volume, a plasma chyle detection system based on CCD (TCD1304) is built by using the advantages of charge coupled device (CCD) and high sensitivity and reliability. The plasma milk chylic detection system is composed of LED light source, optical path system, photoelectric converter and signal processing system, etc. The system selects TCD1304AP as photoelectric converter, built the drive circuit for its use of CPLD, using the AD9945 chip to the optical signal collected by CCD is converted into digital signal, using SPI communication digital signal data is transmitted to the ARM9 series S3C2440 processor, and through the LCD display results. The plasma chyle measurement system designed in this paper was used to calibrate the plasma with different chyle levels, and the criterion of rapid plasma chyle was obtained. The plasma chyli was detected and determined by this criterion. The experimental results show that the detection system can quickly and accurately determine the chylous degree of hemorrhagic lotion. It is proved that the plasma chyle detection system designed in this paper has the advantages of high accuracy, fast and portability.
