Description of the invention: [Technical field to which the invention pertains] In particular, a blood glucose concentration method relates to a measuring device and a method thereof, and a method and a method thereof. [Prior Art] Diabetes is a disease of the eye, and it is expected to be severely ill, such as retinopathy, nephropathy, hypertension, vascular obstruction of the lower extremities. Although there is still no cure for diabetes, it can be through diet and concentration. Therefore, the regular amount of shame concentration is especially important, and the sugar concentration information is effectively controlled. However, the current measurement of blood glucose concentration is mainly based on invasive methods (such as needles), which are obtained by sampling blood and analyzing blood to determine blood glucose concentration. By measuring the blood sugar money through the needle, the patient's silk _ or reliance on the patient's silk can not be implemented regularly to check the monitoring of the disease. Or, when the patient has a purple needle, the needle is stipulated according to the measurement, and only the needle is tied to the vicinity of the skin surface, and then the liquid is squeezed out, which will affect the accuracy of the measurement. Therefore, if you can propose a non-invasive blood glucose measurement method and reduce the blood test, it is bound to help the control of diabetes reading, and can reduce the complications or mortality of diabetes. SUMMARY OF THE INVENTION In view of the above, it is a primary object of the present invention to achieve a non-invasive measurement of blood glucose concentration. The present invention provides a blood glucose concentration measuring device for measuring blood glucose f degree of a test object comprising: a signal source for generating a microwave signal; and a transmission line including a second end and a second end of the first end electrical connection signal The source, the transmission line receives and transmits the microwave signal 并' and is attached to the surface of the object to be tested; the detecting unit is electrically connected to the second end of the transmission line, 4 201205074 is used to detect the microwave signal of the second end, and obtains the detection result; the arithmetic unit, the electrical connection The signal source and the detecting unit are configured to control the frequency at which the signal source generates the microwave signal, and receive the detection result, and calculate the energy loss after the microwave signal is transmitted through the transmission line, thereby converting the blood glucose concentration value; and outputting the unit, electrically connecting the arithmetic unit, Used to output blood glucose concentration values. The invention also provides a blood glucose concentration measuring method for measuring the blood glucose concentration of the sample to be tested, comprising: providing a microwave signal; detecting the energy loss of the microwave signal portion absorbed by the object to be tested; and converting the energy loss of the microwave signal to blood sugar Concentration value; and output blood glucose concentration value. The preferred embodiment of the invention and its efficacy are described in conjunction with the drawings. BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to specific embodiments. The symbols mentioned in the description refer to the schema symbols. Referring to Fig. 1, there is shown a block diagram of a first embodiment of the present invention. A blood glucose concentration measuring device </ RTI> is used for measuring the blood glucose concentration of the test object, including the signal source 10, the transmission line 20, the detecting unit 30, the arithmetic unit 40, and the output unit 50. The signal source 10 is used to generate a microwave signal, and the Sweep signal source can continuously generate a microwave signal of an interval frequency (eg, iGHz to 5 GHz). The transmission line 20 includes a first end 21 and a second end 22. The first end 21 is electrically connected to the signal source 10 for transmitting the microwave signal and attached to the surface of the object to be tested. The detecting unit 30 is electrically connected to the second end 22 of the transmission line 20 for detecting the microwave number of the first end 22 to obtain the detection result. The computing unit 4 is electrically connected to the signal source 10 and the detecting unit 30 for controlling the frequency of the microwave signal generated by the signal source 10 and receiving the detection result, and calculating the energy loss of the microwave signal after passing through the transmission line 2, thereby converting the blood glucose concentration into value. The output unit 5 is electrically connected to the arithmetic unit 40 for outputting a blood glucose concentration value. 201205074 Here, the transmission line 20 can be a microstrip line, a Coplanar wave guide, or a slot line. The detecting unit 30 can detect the power of the microwave signal of the second end 22 of the transmission line 2〇 and transmit it to the computing unit 4 (the computing unit 4 can compare the microwave signal and the transmission line 20 generated by the signal source 1). The power of the microwave signal at the second end 22 is used to know the energy loss of the microwave signal after passing through the transmission line 20. Please refer to FIG. 2 as the microwave energy loss and the microwave frequency and blood glucose concentration in the first embodiment of the present invention. It can be seen that when microwaves with a frequency of 1 GHz to 5 GHz are applied, the blood glucose concentration is positively correlated with the microwave energy loss, and is particularly good in the 2 GHz to 3 GHz frequency band. Therefore, the microwave energy loss can be converted into blood glucose concentration. 3 is a block diagram of a second embodiment of the present invention. In addition to the first embodiment, a protective layer 6〇 may be further included on the transmission line 20 for attaching to the object to be tested. The surface can improve the durability of the measuring device. & Please refer to FIG. 4, which is a block diagram of a third embodiment of the present invention. In addition to the first embodiment, the resonance unit 7 may be further included. Hey, in the biography The line 20 is used to absorb part of the microwave signal. Due to the dielectric material of the resonant unit 7〇, a standing wave is formed in the microwave signal resonance unit 70, and most of the microwave signal is retained in the resonance unit 70, and the detection unit 3 is strengthened. 〇 The detected microwave energy loss or the frequency drift of the microwave signal to improve the discrimination of the microwave energy loss to the blood glucose concentration. The 'resonant unit 70 can be a dielectric resonator. Please refer to Figure 5. The present invention is a flow chart of a first embodiment of the present invention. A soil and sugar concentration measuring method comprises the following steps: Step S310: providing a microwave signal. Here, the second figure shows the blood glucose concentration and the microwave frequency. It is also related, therefore, the microwave signal can adjust the frequency according to the situation. Step S330: Detecting the energy loss of the microwave signal part after being absorbed by the object to be tested 201205074. Here, the microwave signal can be approached to the object to be tested, because the absorption part of the object to be tested The microwave signal causes the microwave signal energy loss' and can measure the energy loss of the microwave signal by measuring the power variation of the microwave signal. Step S350: The energy loss of the converted microwave signal is the blood glucose concentration value. In this case, the energy loss caused by the microwave signal passing through the body to be tested can be pushed back to the corresponding blood glucose concentration value. Step S370: The blood glucose concentration value is output. In this case, the blood glucose concentration value can be output to an external device for operation or display on the screen. Before step S330, the method can further include the step S32: absorbing part of the microwave signal to enhance the energy loss of the microwave signal. The dielectric resonator uses the resonant microwave signal to keep part of the microwave signal in the dielectric resonator, and enhances the energy loss of the microwave signal detected in step S330 or causes the frequency of the microwave signal to drift, thereby increasing the microwave energy loss to the blood glucose. The degree of discrimination. In other words, through the dielectric resonator, the energy loss and frequency of the microwave signal can be changed, and the magnitude of the change is related to the blood glucose concentration value. Therefore, the concentration of the gold sugar can be more accurately combined with the two parameters. In summary, the present invention provides a method and apparatus for measuring blood glucose concentration, which can be used to measure blood glucose concentration in a non-invasive manner. Although the technical content of the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and any modifications and refinements made by those skilled in the art without departing from the spirit of the present invention are encompassed by the present invention. The scope of protection of the present invention is therefore defined by the scope of the appended claims.
