Abstract
本发明涉及一种基于耳垂血液层的微波频谱无创血糖浓度检测法,包括:制作耳垂模型;配制不同血糖浓度的测试血液;将两个天线置于耳垂模型的两侧,发射天线发射高频正弦波信号,接收天线接收穿过耳垂模型的高频正弦波信号;改变耳垂模型中血液的血糖浓度,使用不同血糖浓度的血液测试,接收到穿过不同血糖浓度的血液的正弦波;对接收到的信号进行频谱分析,找出频谱图像上的最大峰值,总结出最大频谱幅值关于被测血液血糖浓度的变化规律。根据这一规律,测量出待测血液的频谱峰值,即可计算出被测血液的血糖浓度。
Description
技术领域
本发明属于微波无创检测技术领域,涉及一种血糖浓度检测方法。
背景技术
目前,糖尿病已经成为一种全世界范围内流行的非传染性疾病,空腹检测血糖水平已经成为体检的常规项目,有助于初步筛查糖尿病早期患者。目前临床上使用的血糖检测方法主要为葡萄糖氧化酶(GOD)法,它被称为临床检测上的金标准,检测结果十分准确。除此之外,血糖检测法还包括了有创检测中的光学法,微创检测中的皮下植入法和透皮取样法。这些方法都给患者带来了极大痛苦,特别是对于糖尿病患者而言,每天需要进行数次的血糖检测,一种无创无痛的血糖检测方法亟待开发。目前的无创检测法主要是通过检测身体其他组织(例如皮肤、角膜、口腔粘膜、舌和鼓膜等)或者体液(例如尿液、唾液、汗液、泪液)中的葡萄糖含量,通过数学方法间接计算而得,这些方法准确率低,与临床方法实际测量结果相差较大。
发明内容
本发明提供一种利用高频正弦波无创检测人体血糖浓度的方法。该方法检测的目标组织为耳垂组织,通过比较发射和接收波形的频谱幅值,计算耳垂组织血液层的相对介电常数值,通过血糖浓度与相对介电常数的对应关系,间接计算出患者的血糖浓度水平。这样的方法避免了对人体有害的有创检测方法,本发明的技术方案如下:
一种基于耳垂血液层的微波频谱无创血糖浓度检测法,包括下列步骤:
1)制作耳垂模型;
2)配制不同血糖浓度的测试血液;
3)将两个天线置于耳垂模型的两侧,发射天线发射高频正弦波信号,接收天线接收穿过耳垂模型的高频正弦波信号;
4)改变耳垂模型中血液的血糖浓度,使用不同血糖浓度的血液测试,接收到穿过不同血糖浓度的血液的正弦波;
5)对接收到的信号进行频谱分析,找出频谱图像上的最大峰值,总结出最大频谱幅值关于被测血液血糖浓度的变化规律。根据这一规律,测量出待测血液的频谱峰值,即可计算出被测血液的血糖浓度。
附图说明
图1简化耳垂组织模型及天线结构示意图
图2介电常数在68-70之间变化时,接收波的时域图
图3介电常数在68-70之间变化时,接收波的频谱图
具体实施方式
图1为耳垂组织结构的简单模型,为了简单起见,模型中分成了血液层和皮肤层,来验证该方法的有效性。两个天线分别放置在耳垂组织的两侧,分别用于发射和接收高频正弦波。血液层的浓度范围为0~4000mg/dL,对应不同浓度的血液层电测参数如表1所示。
表1不同血糖浓度的血液层对应电磁参数
具体过程如下:
1.建立耳垂组织模型如图1所示,发射天线和接收天线都位于皮肤层表面。
2.设置发射天线发出的波形为频率为1GHz的单频正弦波,得到接收波形。
3.改变血液层的相对介电常数值,使得相对介电常数在68-70之间以0.5为单位变化,代表了血液层血糖浓度值的变化。
4.将五条接收曲线绘制在同一张图像上,如图2所示,可以看出,当血液的介电常数变化时,接收波在时域上有幅值的变化,这表明,通过血糖浓度不同的血液时,正弦波的能量受到损失。
5.在频域图上可以看出,如图3所示,当血液的相对介电常数为70(即血糖浓度为0mg/dL)时,接收波的频谱幅值为3126.98,并以此为基准,介电常数每减小0.5,即血糖浓度每增加1000mg/dL,接收波频谱幅值增加0.128‰(万分之0.128)。
6.设实际测得某一接收波频谱幅值为x,测出穿过蒸馏水的接收波频谱幅值为y并以其为基准,则由上述表1可以整理得,被测血液的血糖浓度为:
