Description

TECHNICAL FIELD

[0001] The present application relates to a non-invasive glucose detection device, in particular to a saliva glucose detection device based on wireless radio frequency signals. BACKGROUND

[0002] With the improvement of living standards and the change of eating habits, diabetes has become a major public health problem worldwide. For diabetic patients, monitoring the glucose in the body at all times is the core means of precise disease management, prevention of complications and maintenance of life quality.

[0003] Traditional glucose detection methods usually rely on collecting blood samples and using electrochemical sensors or spectroscopic instruments for analysis. The specific detection method is to implant a small probe with enzymes such as glucose oxidase or glucose dehydrogenase under the skin and in contact with interstitial fluid, based on the correlation between the glucose concentration in interstitial fluid and the glucose concentration in blood, the glucose level is tested by monitoring the change of glucose concentration in interstitial fluid, the disadvantage is that the probe is made of high-precision processing, the cost is high, and the probe invades the skin, which will bring pain and psychological pressure to the patient, and increase the risk of infection. In other words, the traditional blood glucose detection method is not only cumbersome to operate, but also brings pain and infection risk to the patient. Therefore, it is of great significance to develop a non-invasive and convenient glucose detection method.

[0004] In recent years, saliva glucose detection sensors have gradually attracted attention. Compared with blood, saliva samples are easier to collect, non-invasive, and can reflect the changes in glucose levels in the human body. However, the existing saliva glucose detection sensors still have some problems:

[0005] 1. Complex manufacturing process: The electrochemical sensor in the current saliva glucose detector usually contains a working electrode, a reference electrode and an auxiliary electrode. When the saliva sample contacts the sensor, glucose undergoes oxidation reaction on the electrode, generating current. By measuring the size of the current, the concentration of glucose in saliva can be calculated, and the electrode used in such a sensor needs to be made by a complex electrochemical process.

[0006] 2. High component cost: The current saliva glucose detector needs to combine wired transmission or Bluetooth transmission to transfer data, resulting in high overall cost of the saliva glucose detector.

[0007] These problems of the above saliva glucose detection devices greatly limit the wide application of saliva glucose detection sensors. SUMMARY

[0008] The saliva glucose detection device based on wireless radio frequency signals aims to provide a solution capable of non-invasive, rapid and accurate detection of glucose content in saliva, which simplifies the manufacturing process, reduces the cost, and improves the convenience and accuracy of detection.

[0009] To achieve the above object, the technical scheme provides a saliva glucose detection device based on wireless radio frequency signals, which comprises a device base, wherein the device base is provided with a saliva flow channel; a saliva inlet communicating with one end of the saliva flow channel; a saliva glucose sensor arranged at one end of the saliva flow channel; a reading device located above the saliva glucose sensor; and a data analysis end connected with the reading device.

[0010] Compared with the prior art, the technical scheme has the following characteristics and beneficial effects:

[0011] The reading device in the utility model is made of low-cost materials and does not need to use high-precision processing equipment. In addition, the preparation raw materials of the glucose response sensor are easy to obtain and low in price, further reducing the production cost.

[0012] The portable saliva glucose detection device improves the convenience of detection. The portable saliva glucose detection device does not need to collect blood samples, and only needs to drop saliva into the device inlet to perform detection. At the same time, the data receiver adopts wireless radio frequency technology, and can read data without wired connection, improving the convenience of detection.

[0013] The utility model improves the accuracy of detection. The utility model utilizes the sensitive characteristics of the glucose response sensor to glucose and the change of the radio frequency signal to detect the glucose content in saliva. BRIEF DESCRIPTION OF DRAWINGS

[0024] a reading device 500 located above the saliva glucose sensor 400;

[0025] and a data analysis end 600 connected with the reading device 500.

When the saliva glucose sensor 400 detects glucose, the wireless radio frequency of the saliva glucose sensor 400 changes and is captured by the reading device 500 to realize the concentration detection of glucose.

[0027] In some embodiments, the saliva inlet 200 is a saliva collector. Preferably, the upper end of the saliva collector is a circular port, and the lower end is embedded in the device base 100, which is used to transport saliva into the saliva flow channel 300.

[0030] In some embodiments, the reaction pool 102 is a groove connected to the upper surface of the device base 100, and the saliva glucose sensor 400 is arranged in the reaction pool to facilitate signal transmission to the reading device 500.

[0031] In some embodiments, the reading device 500 is a substrate etched or printed with an antenna for generating and receiving wireless radio frequency signals.

[0032] Preferably, the shape and size of the antenna pattern of the reading device 500 can be adjusted according to actual needs, and the resulting antenna should have good conductivity and stability to ensure the transmission effect of the wireless radio frequency signals. In some embodiments, the reading device 500 is an ultra-wideband circular antenna, an ultra-wideband square antenna or an ultra-wideband special-shaped antenna.

[0033] In some embodiments, the data analysis end 600 selects a vector network analyzer for receiving the wireless radio frequency signals transmitted by the inductive coil of the reading device 500 and converting them into readable glucose concentration values. The selection of the vector network analyzer should be considered according to actual needs to ensure the reading range and accuracy of the signals.

[0034] In some embodiments, the saliva glucose detection device based on wireless radio frequency signals is printed using three-dimensional printing technology.

[0035] Those skilled in the art should understand that the technical features of the above embodiments can be combined in any way, and for the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered as the scope of the present disclosure.
