血糖，指的是血液中所含的葡萄糖。消化后的葡萄糖由小肠进入血液，并被运输到机体中的各个细胞，是细胞的主要能量来源。正常人的血糖浓度相对稳定，落在一个可确定的血糖浓度范围之内。Blood sugar refers to the glucose contained in the blood. Digested glucose enters the bloodstream from the small intestine and is transported to individual cells in the body, which is the main source of energy for the cells. Normal people's blood glucose levels are relatively stable and fall within a determinable range of blood glucose concentrations.

血糖必须保持一定的水平才能维持体内各个器官和组织的需要。血糖浓度一般在进食一到二个小时后升高，而在早餐降到最低。血糖浓度失调会导致多种疾病，持续性血糖浓度过高的高血糖和过低的低血糖都会给人们身体造成严重的影响，而由多种原因导致的持续性高血糖就会引起糖尿病，这也是血糖浓度相关的最显著的疾病。Blood sugar must be maintained at a certain level to maintain the needs of various organs and tissues in the body. Blood glucose levels generally increase after eating for one to two hours, while minimizing breakfast. Unbalanced blood glucose levels can lead to a variety of diseases. Hyperglycemia and excessive hypoglycemia with persistently high blood glucose levels can have serious effects on the body, and persistent hyperglycemia caused by a variety of causes can cause diabetes. It is also the most significant disease associated with blood glucose levels.

现有技术中存在一些检测血糖的医疗仪器，但这些血糖仪都存在以下缺陷：(1)检测模式单一，只能检测血糖浓度；(2)检测机制落后，结构冗余度过高，精度满足不了日趋增加的精度需求；(3)没有血糖检测和胰岛素供给的控制机制，无法根据被测人体的血糖含量自适应调整被测人员的胰岛素的供给参数，例如，供给速度、供给量等，还需要人工观察血糖含量、人工决策胰岛素供给参数，自动化水平落后；(4)无线通信接口匮乏，不能将与血糖相关的各个参数及时反馈到医疗服务器端，即使存在一些简单的无线通信接口，例如蓝牙通信接口，其匹配机制和连接机制效率低下，满足不了医疗器件的高速度传输数据的要求。There are some medical instruments for detecting blood sugar in the prior art, but these blood glucose meters have the following defects: (1) the detection mode is single, and only the blood glucose concentration can be detected; (2) the detection mechanism is backward, the structural redundancy is too high, and the precision is satisfied. There is no increasing demand for precision; (3) there is no control mechanism for blood glucose detection and insulin supply, and it is impossible to adaptively adjust the insulin supply parameters of the test subject according to the blood sugar content of the measured human body, for example, supply speed, supply amount, etc. Manual observation of blood glucose levels, artificial decision-making insulin supply parameters, automation level backward; (4) lack of wireless communication interface, can not timely feedback the various parameters related to blood glucose to the medical server, even if there are some simple wireless communication interfaces, such as Bluetooth The communication interface, its matching mechanism and connection mechanism are inefficient, and can not meet the requirements of high-speed transmission of data of medical devices.

为此，本发明提出了一种无创式血糖仪，能够改善落后的血糖仪的结构，将血氧饱和度检测融入到血糖仪中，拓宽检测的生理参数的范围，提高血糖检测的精度，能够建立血糖自动控制的胰岛素供给体系，减少人工参与，另外，还能够改善现有的蓝牙通信机制，提高无线数据传输的速度和效率。To this end, the present invention proposes a non-invasive blood glucose meter, which can improve the structure of the backward blood glucose meter, integrate blood oxygen saturation detection into the blood glucose meter, broaden the range of physiological parameters detected, and improve the accuracy of blood glucose detection. Establish an insulin supply system with automatic blood glucose control to reduce manual participation. In addition, it can improve the existing Bluetooth communication mechanism and improve the speed and efficiency of wireless data transmission.
