[0032] See also Figure 1 to Figure 4 , the following combination Figure 1 to Figure 4 A non-invasive blood glucose sensor provided in an embodiment of the present application is described in detail.

[0033] The present application embodiment provides a non-invasive blood glucose sensor, such as Figure 1 to Figure 4 As shown, the non-invasive blood glucose sensor includes a protective component 1 and a detection component 2, wherein the detection component 2 is arranged in the protective component 1, the protective component 1 includes a shell structure 11 and a protective member 12, the detection component 2 is arranged on the inner side of the shell structure 11, and the protective member 12 is arranged on the top of the shell structure 11; the detection component 2 includes a detection body 21 and a heat dissipation mechanism 22, the heat dissipation mechanism 22 is arranged on the detection body 21, and the heat dissipation mechanism 22 is used to cool the inside of the detection component 2.

[0034] In the embodiment of the present application, a protective member 12 is provided at the top of the shell structure 11, and the detection component 2 is provided on the inner side of the shell structure 11 to protect the detection component 2. At the same time, a heat dissipation mechanism 22 is provided on the detection body 21 so that the heat dissipation mechanism 22 can be used to cool the inside of the detection component 2 to reduce the temperature inside the detection component 2. This can avoid errors and fluctuations in numerical values ​​during the detection process due to excessively high temperatures inside the detection component 2, thereby improving the reliability and stability of the non-invasive blood glucose sensor.

[0035] In some specific embodiments, Figure 1 and Figure 2As shown, the shell structure 11 can be an annular structure, and the top end of the shell structure 11 is the end close to the protective member 12, that is, the top end of the shell structure 11 is the upper end of the shell structure 11, and the protective member 12 can be solidified glass. Furthermore, by arranging the protective member 12 at the upper end of the shell structure 11, the protective member 12 can be used to protect the detection component 2 located inside the shell structure 11, thereby preventing the detection component 2 from being damaged by the outside world.

[0036] In a specific embodiment, the protective component 1 further includes a display element 13 and a charging port 14 ; wherein the display element 13 is disposed between the protective element 12 and the shell structure 11 , and the charging port 14 is disposed on the outer side wall of the shell structure 11 .

[0037] In the embodiment of the present application, the display component 13 is disposed between the protective component 12 and the shell structure 11 so that the display component 13 can be protected by the protective component 12. This can prevent the display component 13 from being damaged by foreign objects hitting the display component 13 when the non-invasive blood glucose sensor falls, thereby extending the service life of the display component 13.

[0038] In actual applications, the display member 13 may be an external display screen for displaying the detected blood sugar data, wherein one end of the display member 13 is fixedly connected to the protective member 12, and the other end of the display member 13 is fixedly connected to the top of the housing structure 11, so as to fix the display member 13.

[0039] Furthermore, a charging port 14 is provided on the outer side wall of the shell structure 11 so that the charging port 14 can be used to connect an external charging device or a charging connector to charge the non-invasive blood glucose sensor.

[0040] It should be noted that the non-invasive blood glucose sensor in the present application is an integrated pixel non-invasive blood glucose sensor, wherein the integrated pixel non-invasive blood glucose sensor is a new type of blood glucose monitoring equipment, which measures blood glucose levels in a non-invasive manner. Specifically, the blood glucose concentration is inferred by detecting the reflection spectrum on the skin. First, the non-invasive blood glucose sensor emits a light beam of a specific wavelength to the user's skin, and then the integrated pixel non-invasive blood glucose sensor receives the light beam reflected from the skin. Since changes in blood glucose concentration affect the absorption and reflection characteristics of blood to light, blood glucose concentration can be inferred by analyzing changes in the reflection spectrum. In addition, the non-invasive blood glucose sensor also integrates multiple pixels, each of which can independently detect and analyze the reflection spectrum. This multi-pixel design can obtain more data information from multiple angles and positions to improve the accuracy and stability of the measurement.

Since the detection component 2 is arranged inside the shell structure 11, the connection and fixation between the wearable component 3, the protective component 1 and the detection component 2 can be realized.

[0055] In actual applications, the fixing member 32 may be an annular structure, and the inner wall of the fixing member 32 matches the outer wall of the shell structure 11 to facilitate the connection and fixation between the wearable component 3 and the protective component 1.

In a specific embodiment, a sandwich layer is provided inside the connecting ring 33, and the sandwich layer inside the connecting ring 33 helps to install the wearing belt 31. At the same time, the sandwich layer inside the connecting ring 33 is detachable so that the wearing belt 31 can be disassembled and cleaned.
