[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0033] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0034] See also Figure 1 , Figure 1 This is a partial structural diagram of the blood glucose meter provided by an embodiment of the present invention. It is understood that the blood glucose meter 100 is also equipped with other components (not shown in the figure), such as the probe 4, a bracket, an elastic member, a pressing member, and a seal. Of course, the blood glucose meter 100 can be specifically designed according to the specific application scenario and may not include the other components not shown in the aforementioned figure. Since the other components not shown in this part of the figure are not the key innovative technical points of this application, they will not be described in detail in this embodiment and will not be shown in the figures.

[0035] The blood glucose meter 100 is used to measure the blood glucose level of a user or patient.

[0036] Specifically, see Figure 2 , Figure 2 Shown Figure 1 The three-dimensional exploded view of the blood glucose meter shown. In this embodiment, the blood glucose meter 100 includes a shell 2 and a control module 1, a sensor unit 3 and a probe 4 arranged in the shell 2. The probe 4 is used to penetrate the sampling site to obtain a sample, and obtain the original data in the sample through the sensor unit 3 or transmit the sample to the control module 1 for processing, conversion and transmission. In this embodiment, the shell 2 includes an upper shell component 21 and a lower shell component 22. The upper shell component 21 and the lower shell component 22 are enclosed to form a cavity. The control module 1, the sensor unit 3 and the probe 4 are all arranged in the cavity. Since the shell 2 is not an innovative design point of the embodiment of the present application, it will not be repeated here.

[0037] The blood glucose monitor 100 may also be a continuous blood glucose monitor 100, which is worn on a certain part of the body of the user or patient to continuously monitor, analyze and manage the data.

[0038] Specifically, see Figure 3 , Figure 3 It is a partial structural diagram of another blood glucose meter provided by an embodiment of the present utility model. In this embodiment, the blood glucose meter 100 may not include the probe 4. The blood glucose meter 100 can be worn directly on a certain part of the body of the user or patient to continuously monitor their blood glucose, and transmit the monitoring data to the control module 1 through the sensor unit 3 for processing, conversion and transmission. In this embodiment, the blood glucose meter 100 includes a shell 2 and a control module 1 arranged in the shell 2, and the control module 1 processes, converts and transmits the collected raw data. The blood glucose meter 100 may also include a sensor unit 3, which is used to obtain relevant raw data such as blood glucose, and transmit it to the control module 1 for processing, conversion and transmission.

[0039] Among them, the control module 1 in the aforementioned embodiment can be connected to external devices such as mobile phones, tablets, computers and other electronic devices, and process, convert and transmit blood glucose detection data to external devices, thereby facilitating subsequent big data analysis and organization, and facilitating the user's blood glucose level management.

[0040] Combine Figure 1 and Figure 3 It can be seen that the specific structure and appearance of the housing 2 of the blood glucose detector 100 are designed according to product design requirements. Figure 1 and Figure 3 The shape of the housing 2 shown in FIG. 1 is only a schematic diagram for ease of understanding.

[0041] Since the application scenarios of the blood glucose monitor 100 are different, the internal structure is also different, and other components are not the key innovative technical points of the embodiment of the present application. Therefore, the embodiment of the present application will be described in detail below with reference to the accompanying drawings for the key innovative part of the control module 1 of the embodiment of the present application.

[0042] See also Figure 4 , Figure 4 This is a three-dimensional diagram of the control module of the blood glucose meter provided in an embodiment of the present application. The control module 1, as part of the blood glucose meter 100, includes a circuit board, specifically a printed circuit board 15. The other components of the control module 1 are all mounted on the printed circuit board 15. The printed circuit board 15 has a first mounting portion 151 for mounting the sensor unit 3. The first mounting portion 151 is a hole extending through the printed circuit board 15.

[0043] Specifically, see Figure 4 、 Figure 5 and Figure 6 , Figure 5 yes Figure 4 A perspective exploded view of the control module of the blood glucose tester shown; Figure 6 yes Figure 4 A schematic diagram of the control module of the blood glucose monitor shown in FIG. The control module 1 includes a first antenna 11, a main control unit 12, a wireless communication control unit 13, and a second antenna 14; the first antenna 11, the main control unit 12, the wireless communication control unit 13, and the second antenna 14 are all disposed on a printed circuit board 15.

[0044] The first antenna 11 is configured to receive a first radio frequency signal, which is an NFC radio frequency signal. A main control unit 12 is electrically connected to the first antenna 11 and is configured to receive the NFC radio frequency signal to initiate operation. After activation, the main control unit 12 processes the raw data output by the sensor unit 3 to obtain detection data. A wireless communication control unit 13 is electrically connected to the main control unit 12 and is configured to receive the detection data and output a second radio frequency signal. A second antenna 14 is electrically connected to the wireless communication control unit 13 and is configured to receive the second radio frequency signal for wireless transmission.

[0045] Compared with the prior art, the control module 1 provided in this application processes, converts and transmits the detection data to the external interactive device through the connection and cooperation of the first antenna 11, the main control unit 12, the wireless communication control unit 13 and the second antenna 14, thereby achieving efficient data processing, wireless communication and data transmission, and facilitating the use of big data for analysis and management. The first antenna 11 is used to receive NFC radio frequency signals, and the main control unit 12 is electrically connected to the first antenna 11. The main control unit 12 only starts working after receiving the NFC radio frequency signal; when the external interactive device transmits an NFC radio frequency signal to the first antenna 11, the main control unit 12 receives the NFC radio frequency signal and starts working. Conversely, when the external interactive device does not transmit an NFC radio frequency signal to the first antenna 11, the main control unit 12 is in a standby state, thus achieving extremely low power consumption of the entire device.

[0046] See also Figure 4-Figure 6 , the first antenna 11 includes a conductive circuit formed on a printed circuit board 15; the first antenna 11 is formed on the bottom and top layers of the printed circuit board 15 through a winding layout; the number of windings of the first antenna 11 is greater than or equal to 4. This allows the first antenna 11 to be arranged over a wide range to facilitate receiving the first radio frequency signal. For example, the printed circuit board 15 may include a first base layer, a second base layer, a third base layer, and a fourth base layer stacked in sequence; the first base layer is provided with one loop of the first antenna 11, the second base layer is not provided with the first antenna 11, the third base layer may be provided with two loops of the first antenna 11, and the fourth base layer is provided with one loop of the first antenna 11; the printed circuit board 15 also includes a via hole, which passes through the first base layer, the second base layer, the third base layer, and the fourth base layer; the first antennas 11 in different base layers are connected through the via hole.

[0047] See also Figure 4-Figure 6In order to realize power supply, the control module 1 further includes a battery module 16 ; the battery module 16 is arranged on the printed circuit board 15 .

[0048] Since the blood glucose detector 100 provided in the embodiment of the present application is used for blood glucose monitoring, it needs to be sterilized by irradiation to protect the sensitive components in the control module 1 from being damaged; the control module 1 also includes a shielding component 17; the shielding component 17 is arranged on one side of the main control unit 12, and the shielding component 17 is used to block at least part of the radiation light to form a full-shadow shielding area to protect the main control unit 12. By designing the shielding component 17, the full-shadow shielding area formed by the shielding component 17 can better avoid the damage caused by the main control unit 12 being exposed to the radiation light, thereby ensuring the control accuracy and service life of the control module 1. Of course, in other embodiments, only the battery module 16 can be used to shield and block the radiation light.

[0049] Specifically, see Figure 4-Figure 6 The printed circuit board 15 further has a second mounting portion 152 ; the second mounting portion 152 is used to mount the shielding assembly 17 . The second mounting portion 152 is a hole that passes through the printed circuit board 15 .

[0050] The shielding assembly 17 includes a shielding block 171 and / or a shielding bracket 172. For example, in an embodiment of the present application, the shielding assembly 17 includes a shielding block 171 and a shielding bracket 172; the shielding bracket 172 is disposed at the second mounting portion 152 and supports the shielding block 171; the shielding block 171 is positioned above the main control unit 12, thereby forming a full-shadow shielding area to block radiation from one direction. The density of the shielding block 171 is greater than 1000 kilograms per cubic meter; and the greater the density of the shielding block 171, the greater the effectiveness of the shielding block 171 in blocking radiation. The shape of the shielding block 171 can be plate-shaped, block-shaped, or other shapes, and this embodiment does not impose specific limitations. Of course, in other embodiments, the shielding assembly 17 can also include only the shielding block 171, as long as it can block and form a full-shadow shielding area. For another example, in another embodiment, the shielding assembly 17 can also include only the shielding bracket 172, with the shielding bracket 172 forming the full-shadow shielding area.

[0051] In order to further prevent the main control unit 12 from being damaged by the radiation light, the battery module 16, the shielding assembly 17 and the main control unit 12 are located in a straight line, and the battery module 16 and the shielding assembly 17 are used to jointly block at least part of the radiation light, thereby ensuring that the radiation light in this direction is blocked.

[0052] The wireless communication control unit 13 is disposed in a full shadow shielding area, which can effectively prevent the wireless communication control unit 13 from being damaged by radiation, thereby ensuring the control accuracy and service life of the control module 1.

[0053] See also Figure 4-Figure 6 The control module 1 further includes a sensing unit connector 18 ; the sensing unit connector 18 is disposed on the printed circuit board 15 , and the sensing unit 3 connector is used to electrically connect between the sensing unit 3 and the main control unit 12 .

[0054] Specifically, to further reduce the volume of the control module 1 and thereby miniaturize the blood glucose monitor 100, in this embodiment, the printed circuit board 15 is circular, and the battery module 16, first mounting portion 151, sensor unit 3 connector, main control unit 12, and wireless communication control unit 13 are sequentially arranged around the second mounting portion 152. This design makes the layout of the control module 1 more compact and smaller in size.

[0055] The two ends of the first antenna 11 are respectively connected to the main control unit 12 and form a ring-shaped area; the battery module 16, the first installation part 151, the sensor unit connector 18, the main control unit 12, the wireless communication control unit 13, and the second installation part 152 are all located in the ring-shaped area. Such a design facilitates the processing, conversion, and transmission of detection data between the first antenna 11 and the sensor unit 3, the main control unit 12, and the wireless communication control unit 13, achieving efficient data processing, wireless communication, and data transmission, and facilitating the use of big data for analysis and management; and makes the first antenna 11, the sensor unit 3, the main control unit 12, the wireless communication control unit 13, and the shielding component 17 more compact in spatial structure, which can further reduce the overall size of the blood glucose detector 100, thereby miniaturizing the product.

[0056] The second antenna 14 is arranged around the battery module 16, the second mounting portion 152, the wireless communication control unit 13, the main control unit 12, and the sensor unit connector 18. This design facilitates the processing, conversion, and transmission of detection data between the second antenna 14 and the sensor unit 3, the main control unit 12, and the wireless communication control unit 13, achieving efficient data processing, wireless communication, and data transmission, and facilitating the analysis and management of big data. Furthermore, the second antenna 14, the sensor unit 3, the main control unit 12, the wireless communication control unit 13, and the shielding assembly 17 are arranged more compactly in space, further reducing the overall size of the blood glucose monitor 100 and miniaturizing the product.

[0057] The second antenna 14 is arranged around the periphery of the first antenna 11. This design makes the second antenna 14 and the first antenna 11 more compact in spatial structure, which can further reduce the size of the blood glucose monitor 100, thereby miniaturizing the product.

[0058] The length of the second mounting portion 152 is greater than or equal to 3 mm, and the width of the second mounting portion 152 is greater than or equal to 2 mm. This design ensures that the shielding component 17 is large enough to provide good shielding for the main control unit 12 and the wireless communication control unit 13.

[0059] The diameter of the printed circuit board 15 is less than or equal to 22 mm. This design ensures that the printed circuit board 15 provides sufficient space for the first antenna 11, the second antenna 14, the sensor unit 3, the main control unit 12, the wireless communication control unit 13, and the shielding assembly 17, while also reducing the overall size of the blood glucose monitor 100, thereby miniaturizing the product.

[0060] See also Figure 4-Figure 6 Second antenna 14 is a metal frame antenna. The metal frame antenna includes an antenna body 141 positioned above a printed circuit board 15 and at least one feeder 142 connecting the antenna body 141 and the printed circuit board 15. Feeder 142 is electrically connected to wireless communication control unit 13 via a microstrip line. With this design, the second RF signal output by wireless communication control unit 13 is transmitted via the microstrip line to feeder 142, which then transmits it to antenna body 141 for wireless transmission.

[0061] The microstrip line comprises a circuit formed on a printed circuit board 15. Microstrip is a type of transmission line commonly used in microwave and millimeter wave frequency bands. Its characteristic is that the electromagnetic field is primarily confined to a relatively thin dielectric layer, and electromagnetic wave transmission and manipulation are achieved through three basic components: a patch, a ground plane, and a dielectric substrate. In this embodiment, the characteristic impedance of the microstrip line is 50Ω. Electrical connections achieved through microstrip lines simplify the layout and wiring between units, improve circuit stability, reduce electromagnetic interference, optimize frequency matching, and enhance the performance of wireless communication devices.

[0062] At least one feed portion 142 is provided with an antenna clearance area. The antenna clearance area refers to the space between the antenna and the surrounding objects, which is crucial to the performance of the antenna. The antenna clearance area ensures that the antenna has enough space to avoid shielding or interference, ensuring the omnidirectional communication effect of the second antenna 14. Providing an antenna clearance area in the feed portion 142 can ensure that the signal of the second antenna 14 is less obstructed, thereby improving the transmission quality and coverage range of the signal of the second antenna 14. It is worth mentioning that the first antenna 11 and the second antenna 14 can be preset with sufficient antenna clearance area on the printed circuit board 15 for avoidance, so that the transmission efficiency of the first antenna 11 and the second antenna 14 can meet the requirements.

[0063] Specifically, see Figure 4-Figure 6At least one feeding part 142 includes a first pin 142a, a second pin 142b, a third pin 142c and a fourth pin 142d; the first pin 142a, the second pin 142b, and the third pin 142c are connected in sequence; the first pin 142a and the second pin 142b are both ground feeding pins; the third pin 142c is the antenna feeding point; and the fourth pin 142d is left floating.

[0064] The first pin 142a and the second pin 142b are disposed near the battery module 16. This design facilitates electrical connection between the first pin 142a, the second pin 142b and the battery module 16, and makes the first pin 142a, the second pin 142b and the battery module 16 more compact in spatial structure, further reducing the overall size of the blood glucose monitor 100, thereby miniaturizing the product.

[0065] The third pin 142c is located near the wireless communication control unit 13 and is electrically connected to the wireless communication control unit 13 via a microstrip line. This design facilitates the electrical connection between the third pin 142c and the wireless communication control unit 13 and makes the third pin 142c and the wireless communication control unit 13 more compact in spatial structure, further reducing the overall size of the blood glucose monitor 100, thereby miniaturizing the product.

[0066] The fourth pin 142d is disposed close to the main control unit 12. This design facilitates electrical connection between the fourth pin 142d and the main control unit 12, and makes the fourth pin 142d and the main control unit 12 more compact in spatial structure, further reducing the overall size of the blood glucose monitor 100, thereby miniaturizing the product.

[0067] The antenna clearance area includes a first clearance area 1a; the third pin 142c is disposed in the first clearance area 1a. This design ensures that the second radio frequency signal output by the wireless communication control unit 13 is less obstructed, thereby improving the transmission quality and coverage of the second radio frequency signal.

[0068] The antenna clearance area also includes a second clearance area 1b; the fourth pin 142d is disposed in the second clearance area 1b. This design ensures that the NFC radio frequency signal received by the main control unit 12 is less obstructed, thereby improving the transmission quality and coverage of the NFC radio frequency signal.

[0069] More specifically, the first pin 142a, the second pin 142b, the third pin 142c, and the fourth pin 142d have the same height, which is greater than or equal to 1.3 mm. Properly designing the heights of the first pin 142a, the second pin 142b, the third pin 142c, and the fourth pin 142d facilitates electrical connection between the corresponding components.

[0070] The area of the first clearance zone 1a is greater than or equal to 8mm 2 By reasonably designing the area of the first clear area 1a so that the coverage of the first clear area 1a is large enough, it can effectively ensure that the second radio frequency signal output by the wireless communication control unit 13 is less obstructed, thereby further improving the transmission quality and coverage of the second radio frequency signal.

[0071] The area of the second clearance zone 1b is greater than or equal to 6mm 2 By reasonably designing the area of the second clearance zone 1b so that the coverage of the second clearance zone 1b is large enough, it can effectively ensure that the NFC radio frequency signal received by the main control unit 12 is less obstructed, thereby further improving the transmission quality and coverage of the NFC radio frequency signal.

[0072] See also Figure 4-Figure 6 The wireless communication control unit 13 includes a Bluetooth communication chip; the Bluetooth communication chip is a BLE Bluetooth communication chip. The BLE Bluetooth communication chip is compact, further reducing the product's design size. Specifically, the low-power BLE Bluetooth communication chip implements stable and convenient wireless data transmission, operating with low energy consumption to extend the device's battery life.
