技术领域technical field
本发明属于血糖监测技术领域，具体涉及一种生物电阻抗检测仪及检测方法。The invention belongs to the technical field of blood sugar monitoring, and in particular relates to a bioelectrical impedance detector and a detection method.
背景技术Background technique
生物阻抗技术（BMI）是一种无损伤检测技术，它利用生物组织和器官的电特性(如阻抗、导纳、介电常数)及变化来提取有关人体生理，病理状况的生物医学信息。其应用范围很广，例如体积测量，人体组织结构分析和人体成分分析。Bio-impedance technology (BMI) is a non-destructive detection technology, which uses the electrical properties (such as impedance, admittance, dielectric constant) and changes of biological tissues and organs to extract biomedical information about human physiological and pathological conditions. It has a wide range of applications, such as volume measurement, analysis of human tissue structure and body composition analysis.
糖尿病为中老年人的常见病、多发病，血糖监测帮助患者及时了解自身的血糖情况以及药物治疗效果，目前临床常用的无创血糖仪：（1）红外无创检测血糖仪，该检测可以通过对患者手指、手掌、额头等部位进行照射来实现，不足之处在于容易受到患者体温以及血压等因素的影；（2）拉曼光谱相比红外光谱具有更高的波长并且光谱段狭窄，更容易进行信号分离，且采集时间较长，同时激光的强度会对监测结果产生较大的影响。能量代谢守恒血糖检测技术主要是基于生物学理论，采用近红外技术对血压含氧量等进行动态检测，建立能量守恒模型对患者体内的葡萄糖水平进行检，但是该无创血糖仪在正式使用之前需要进行校准并且代谢热量受外界影响极大，增加使用难度。Diabetes is a common disease and frequently-occurring disease of middle-aged and elderly people. Blood glucose monitoring helps patients keep abreast of their own blood sugar status and the effect of drug treatment. Currently, non-invasive blood glucose meters are commonly used in clinical practice: (1) Infrared non-invasive blood glucose detection meter, which can be detected by irradiating the patient’s fingers, palms, forehead and other parts. The disadvantage is that it is easily affected by factors such as the patient’s body temperature and blood pressure. Energy metabolism conservation blood glucose detection technology is mainly based on biological theory, using near-infrared technology to dynamically detect blood pressure and oxygen content, and establish an energy conservation model to detect glucose levels in patients. However, the non-invasive blood glucose meter needs to be calibrated before official use, and the metabolic heat is greatly affected by the outside world, which increases the difficulty of use.
生物电阻抗(biological impedance spectroscopy，BIS)方法是一种利用生物组织的电阻抗特性提取相应生理、病理信息的检测技术。该方法通过对被测物体施加幅值较小的交流激励，使用扫频的方式测量每种频率下检测目标对应的阻抗值。BIS技术通过交流电阻抗技术检测生物细胞的电导率和介电常数，并引入电介质物理模型的数值计算，获得细胞外液、细胞膜和细胞质的电学信息，由此来区分不同种类的细胞。因此，BIS成为研究细胞结构特性及细胞分类识别的一种新方式。基于生物电阻抗的医学检测技术越来越多的应用于研究与临床中,主要是由于人体的电阻抗特性和生物电阻抗法的原理所决定的。当人体通过不同频率的交流电流时候,随着频率的不同,所穿透人体组织深度也不同,并且不同人体组织表现为不同的电阻抗特性,所以可以根据这个特性来测量人体组织与器官的生理、病理信息；The biological impedance spectroscopy (BIS) method is a detection technology that uses the electrical impedance characteristics of biological tissues to extract corresponding physiological and pathological information. This method applies an AC excitation with a small amplitude to the measured object, and uses a frequency sweep method to measure the impedance value corresponding to the detection target at each frequency. BIS technology detects the conductivity and permittivity of biological cells through alternating current impedance technology, and introduces the numerical calculation of the dielectric physical model to obtain the electrical information of extracellular fluid, cell membrane and cytoplasm, thereby distinguishing different types of cells. Therefore, BIS has become a new way to study the structural characteristics of cells and the identification of cell classification. Medical detection technology based on bioelectrical impedance is more and more used in research and clinical practice, mainly due to the electrical impedance characteristics of the human body and the principle of bioelectrical impedance method. When the human body passes through alternating currents of different frequencies, the depth of penetration into human tissue varies with the frequency, and different human tissues exhibit different electrical impedance characteristics, so the physiological and pathological information of human tissues and organs can be measured according to this characteristic;
近年来，国外多个研究机构将生物阻抗检测技术与无创血糖测试相结合，开辟了无创血糖检测的新方向，出现了基于生物电阻抗检测的抗阻传感器来采集细胞内液变化并采集高低频率阻抗以达到血糖监测目的，具有较高的灵敏度和准确度，能够在不需要任何外部能量刺激下进行检测并显示结果；In recent years, many foreign research institutions have combined bio-impedance detection technology with non-invasive blood sugar testing, opening up a new direction for non-invasive blood sugar detection. Impedance sensors based on bio-electrical impedance detection have emerged to collect changes in intracellular fluid and high and low frequency impedances to achieve blood sugar monitoring purposes. They have high sensitivity and accuracy, and can detect and display results without any external energy stimulation;
而目前已有医疗设备的制造商，将微型NFC血糖传感器植入糖尿病患者皮下，再把搭载专用软件的智能设备靠近传感器所植入的部位，就能随时读取患者的血糖值，目前存在支持NFC刷卡式的血糖仪，包括了血糖仪本体、放大电路、血糖试纸、滤波电路、功能按键、血糖传感器、血糖探头、显示屏、微处理器、供电模块、NFC模块及其天线。不过目前基本上都是有其他的设备中转并不连接手机或者不完全是基于NFC与手机连接，目前基于蓝牙、红外等连接速度慢且比较耗电。At present, manufacturers of medical equipment have implanted miniature NFC blood glucose sensors under the skin of diabetic patients, and then put a smart device equipped with special software close to the implanted part of the sensor to read the blood glucose level of the patient at any time. Currently, there are blood glucose meters that support NFC swiping cards, including the blood glucose meter body, amplifier circuit, blood glucose test strip, filter circuit, function buttons, blood glucose sensor, blood glucose probe, display, microprocessor, power supply module, NFC module and its antenna. However, at present, there are basically other devices that do not connect to the mobile phone or are not completely connected to the mobile phone based on NFC. At present, the connection speed based on Bluetooth and infrared is slow and consumes more power.

具体地，所述瞬感传感器的NFC模块通过NFC发射天线以及手机的NFC接收天线与手机NFC芯片互通，并实现微处理器与手机APP之间的数据发送或传输；Specifically, the NFC module of the transient sensor communicates with the NFC chip of the mobile phone through the NFC transmitting antenna and the NFC receiving antenna of the mobile phone, and realizes data transmission or transmission between the microprocessor and the mobile APP;
穿戴式动态血糖传感器为NFC发起端，用于向着手机APP发送数据，手机为NFC目标设备，手机APP接收来自NFC发起端发送来的数据。The wearable dynamic blood glucose sensor is the NFC initiator, which is used to send data to the mobile APP. The mobile phone is the NFC target device, and the mobile APP receives the data sent from the NFC initiator.

After receiving the data, the mobile phone performs data analysis according to the NDEF data standard. After analysis, the device ID and data information are displayed in the data window;
p2p读取模块与数据读取模块是类似的，都是读取NEDF数据，为的是能够适配更多通信模式。同时，两者也是有区别的，Android Beam是NFC的其中功能之一，有些手机存在NFC功能，但是不一定支持Android Beam功能，使用本模块时需要打开NFC和NFC Beam；带NFC功能血糖传感器测量出相关的数据后，将其保存在文本中，当打开本功能的NFC智能手机靠近血糖传感器时，两者快速连接而后实现数据交换，同样的接收到数据后，本模块将会解析数据并显示数据，通过手动选择，以覆盖保存或者追加保存的方式将数据简单保存到本地。The p2p reading module is similar to the data reading module, both of which read NEDF data in order to be able to adapt to more communication modes.

前面介绍的数据读取模块以及p2p读取模块，这两个模块只是初步保存数据，使用的是文件存储方式，这些数据集没有规定的格式，很难去查询，所以数据库存储模块将会对这些数据进行一定的处理和按照规定的格式保存；The data reading module and the p2p reading module introduced above, these two modules only store data initially, and use the file storage method.

Such data still exists even after the software is uninstalled.
手机APP软件通过相关操作使用智能手机的NFC功能将数据穿戴式动态血糖传感器获取，这些数据先通过TextView初步显示在手机界面，点击保存时将数据初步保存在一个文本里，然后经过专门的数据处理，将存储在LitePal库，通过各种查询到将数据提取到MPChart图表、文本导出和RecyclerView列表等，详见图2中的数据流程图，其中TextView是用来显示字符串的组件，在手机上就是显示一块文本的区域，LitePal是GitHub上一款开源的Android数据库框架。The mobile APP software uses the smart phone’s NFC function to obtain data from the wearable dynamic blood glucose sensor through relevant operations.
