[0039] Figure 1A blood glucose detection device provided in some embodiments of the present application is shown, which specifically includes a portable card-type substrate 1, at least one blood collection unit 2 and a detection unit 3. At least one blood collection unit 2 is arranged at the edge of the portable card-type substrate 1. The blood collection unit 2 includes a groove 4 arranged on the portable card-type substrate 1, and the groove 4 is coated with glucose oxidase or glucose dehydrogenase. The blood collection unit 2 is used to collect blood and generate current. The detection unit 3 is arranged on the portable card-type substrate 1 and is connected to the blood collection unit 2 circuit for detecting the intensity of the generated current and communicating with the outside.

[0040] Here, the size and weight of the portable card-type base 1 are similar to those of bank cards and transportation cards commonly used in daily life, so that the patient can carry it with him when going out and can be placed in a wallet or a handbag.

[0041] The blood collection unit 2 is disposed on the portable card-type base 1, with one end disposed at the edge of the portable card-type base 1 and the other end disposed in the middle area of the portable card-type base 1. The unit is used to collect the patient's blood and generate an electric current based on the chemical reaction of the blood. To facilitate the collection of the patient's blood, some embodiments of the present application further provide a blood collection groove 4 on the portable card-type base 1. The groove 4 is disposed near the edge of the portable card-type base 1, and the inner wall of the groove 4 is also coated with glucose oxidase or glucose dehydrogenase for reacting with glucose in the blood to generate an electric current. The patient's blood can be fully collected through the groove 4, thereby preventing the blood from being dispersed, allowing the blood to fully react with the glucose oxidase or glucose dehydrogenase in the groove 4, thereby avoiding blood glucose detection errors caused by insufficient reaction and improving the accuracy of blood glucose detection.

[0042] In some embodiments of the present application, in order to reduce the tedious operation of replacing test strips each time a patient performs a blood glucose test, a plurality of disposable blood collection units 2 are provided on a portable card-type base 1. The specific number of blood collection units 2 can be considered based on the size and ease of use of the portable card-type base 1, and the number can preferably be set to between 2 and 20.

[0043] In addition, in order to avoid blood contamination between the blood collection units 2, a certain interval is set between each pair of blood collection units 2. The specific interval distance can be determined according to actual usage requirements. Multiple blood collection units 2 can be arranged in sequence along the edge of the portable card-type base 1, and two groups of blood collection units 2 can also be arranged at the same time on the two longer sides of the portable card-type base 1.

[0044] In some embodiments of the present application, the blood collection unit 2 is further covered with a protective film 5, such as Figure 2As shown, the protective film 5 can be used to protect the glucose oxidase or glucose dehydrogenase in the blood collection unit from external contamination or influence, thereby extending the service life and improving the accuracy of detection. In addition, a siphon groove 6 is formed on the protective film 5. The opening of the siphon groove 6 is at the edge of the portable card-type base 1 and is connected to the outside. The other end of the siphon groove 6 extends to the groove 4 in the blood collection unit 2. The siphon groove 6 has a siphoning effect and can siphon the patient's blood at the opening into the groove 4, thereby eliminating the need for the patient to drip blood into the groove 4, facilitating the patient's blood collection operation, and also preventing possible contamination of the vicinity of the groove 4 caused by dripping blood.

[0045] In addition, the blood collection unit 2 is also connected to the detection unit 3 provided on the portable card-type base 1 through a circuit. The blood collection unit 2 transmits the generated current to the detection unit 3. Specifically, the groove 4 in the blood collection unit 2 is connected to the detection unit 3 through a circuit. The current generated by the groove 4 is transmitted to the detection unit 3 through current for current intensity detection. The detection unit 3 can transmit the current intensity data to the external device in real time, or temporarily store the current intensity data and delay transmission, or provide corresponding current intensity data according to the data acquisition request of the external device.

[0046] Here, the connection circuit between the blood collection unit 2 and the detection unit 3 adopts a three-electrode system in electrochemical analysis, such as Figure 3 As shown, the three-electrode system is different from the traditional two-electrode system and includes a working electrode, a reference electrode, and a counter electrode. The reference electrode is used to determine the zero point. The current flows through the working electrode and the reference electrode to form a non-conductive or minimally energized system. The stability of the reference electrode potential is used to measure the electrode potential of the working electrode. The working electrode and the auxiliary electrode form a energized system, which is used to measure the current passing through the working electrode. Using this three-electrode measurement system, the relationship between the working electrode's position and the current can be studied.

[0047] In some embodiments of the present application, the detection unit 3 may include a communication module 7 and a current detection module 8, such as Figure 4 As shown, the communication module 7 is circuit-connected to the current detection module 8. In addition, the blood collection unit 2 is circuit-connected to the current detection module 8. The current generated by the blood collection unit 2 is input into the current detection module 8 for current intensity detection. Preferably, the current detection module 8 can be specifically a current detection chip, which receives the current signal output by the blood collection unit 2 through two electrodes through three electrodes.

[0048] Preferably, the communication module 7 is a near field communication chip. Near Field Communication (NFC) is a short-range, high-frequency wireless communication technology. "Near field" refers to radio waves near the electromagnetic field, which can exchange data when close to each other. It is evolved from the integration of contactless radio frequency identification (RFID) and interconnection technology, and can integrate the functions of inductive card reader, inductive card and point-to-point communication on a single chip.

[0049] In some embodiments of the present application, the blood glucose detection device further includes a temperature detection unit 9, which is disposed on the portable card-type base 1 and is circuit-connected to the communication module 7. Since blood glucose detection requires detection within a certain temperature range to achieve the highest accuracy, for example, detection is most accurate between 18 and 25 degrees Celsius, the temperature during the blood glucose test, obtained by the temperature detection unit 9, can be used to determine whether the obtained blood glucose test result is meaningful.

[0050] Some other embodiments of the present application also provide a blood sugar detection device, such as Figure 5 and Figure 6 As shown, the device specifically includes a portable shell 10 with a cavity, a blood collection needle 11, at least one blood collection unit 2 and a detection unit 3.

The blood collection needle 11 is arranged in the cavity of the portable shell 10.

[0051] Here, the blood collection needle 11 is integrated into the blood glucose testing device to realize the integrated integration of blood collection and blood testing of the patient, which is convenient for the patient to use and avoids the inconvenience caused by the separation of the blood collection needle and the blood glucose testing device.

[0052] The blood collection unit 2 is provided on the portable housing 10, with one end thereof being located on one side of the cavity opening of the portable housing 10 and the other end being located on a side of the portable housing 10 away from the cavity opening, and is used to collect the patient's blood and generate an electric current based on the chemical reaction of the blood. To facilitate the collection of the patient's blood, some embodiments of the present application further provide a groove 4 for collecting blood on the portable housing 10. The groove 4 is provided near the cavity opening close to the portable housing 10, and the inner wall of the groove 4 is also coated with glucose oxidase or glucose dehydrogenase for reacting with glucose in the blood to generate an electric current. The patient's blood can be fully collected through the groove 4 to avoid blood dispersion, so that the blood can fully react with the glucose oxidase or glucose dehydrogenase in the groove 4, thereby avoiding blood glucose detection errors caused by insufficient reaction and improving the accuracy of blood glucose detection.

[0053] Preferably, in order to prevent the blood collection needle 11 from accidentally injuring the patient when blood collection is not needed, the blood glucose detection device is also provided with a blood collection needle protection unit, wherein the blood collection needle 11 is connected to the portable shell 10 through a spring, and the blood collection needle protection unit is embedded in the cavity of the portable shell 10 and is arranged at the front end of the blood collection needle 11.

[0054] Specifically, the lancet protection unit includes a protective head 12 and a protective cover 13. A through hole is provided at the front end of the protective cover 13, and the rear end is embedded in the cavity of the portable shell 10. The lancet 11 can extend through the through hole. A protrusion is provided at one end of the protective head 12. The protrusion is made of soft material and can be used to block the through hole at the front end of the protective cover 13. The lancet 11 can be inserted into the protrusion to prevent the front end of the lancet 11 from injuring the patient.

[0055] In some embodiments of the present application, in order to reduce the tedious operation of replacing test strips each time a patient performs a blood glucose test, a plurality of disposable blood collection units 2 may be provided on the outer wall of the portable housing 10. The specific number of blood collection units 2 may be determined based on the size and ease of use of the portable housing 10, and the number may preferably be set to between 1 and 4.

[0056] In addition, to avoid blood contamination between the blood collection units 2, a certain interval is set between each pair of blood collection units 2. The specific interval distance can be determined according to actual usage requirements. Multiple blood collection units 2 can be arranged around the cavity opening of the portable shell 10.

[0057] In some embodiments of the present application, the blood collection unit 2 is further covered with a protective film 5, such as Figure 7As shown, the protective film 5 can be used to protect the glucose oxidase or glucose dehydrogenase in the blood collection unit from external contamination or influence, thereby extending the service life and improving the accuracy of detection. In addition, a siphon groove 6 is also formed on the protective film 5. The opening of the siphon groove 6 is located at the cavity opening of the portable housing 10 and is connected to the outside. The other end of the siphon groove 6 extends to the groove 4 in the blood collection unit 2. The siphon groove 6 has a siphoning effect and can siphon the patient's blood located at the opening into the groove 4, thereby eliminating the need for the patient to drip blood into the groove 4, facilitating the patient's blood collection operation, and also avoiding possible contamination of the vicinity of the groove 4 caused by dripping blood.

[0058] In addition, the blood collection unit 2 is also connected to the detection unit 3 provided on the portable shell 10 through a circuit. The blood collection unit 2 transmits the generated current to the detection unit 3. Specifically, the groove 4 in the blood collection unit 2 is connected to the detection unit 3 through a circuit. The current generated by the groove 4 is transmitted to the detection unit 3 through current for current intensity detection. The detection unit 3 can transmit the current intensity data to the external device in real time, or temporarily store the current intensity data and delay transmission, or provide corresponding current intensity data according to the data acquisition request of the external device.

[0059] Here, the connection circuit between the blood collection unit 2 and the detection unit 3 adopts a three-electrode system in electrochemical analysis, such as Figure 8 shown.

[0060] In some embodiments of the present application, the detection unit 3 may include a communication module 7 and a current detection module 8 (not shown), and the communication module 7 is circuit-connected to the current detection module 8. In addition, the blood collection unit 2 is circuit-connected to the current detection module 8, and the current generated by the blood collection unit 2 is input into the current detection module 8 for current intensity detection. Preferably, the current detection module 8 can be specifically a current detection chip, which receives the current signal output by the blood collection unit 2 through two electrodes through three electrodes.

[0061] Preferably, the communication module 7 is a near field communication chip.

[0062] In some embodiments of the present application, the blood glucose detection device further includes a temperature detection unit 9 (not shown), which is disposed on the portable housing 10 and is circuit-connected to the communication module 7 .

[0064] Specifically, the mobile terminal includes a near-field communication reader that can be used to obtain the current intensity transmitted by the blood glucose monitoring device. After obtaining the current intensity data, the mobile terminal calculates the corresponding glucose concentration data, i.e., the blood glucose data, according to the corresponding formula between current intensity and glucose concentration. Preferably, a corresponding software application can be installed on the mobile terminal to calculate the blood glucose data.

[0065] In some embodiments of the present application, the blood glucose detection device further includes a temperature detection unit, and the mobile terminal is further configured to receive temperature information obtained by the temperature detection unit. If the temperature information is within a preset temperature range, the blood glucose concentration is determined based on the current intensity. Here, the mobile terminal can determine whether the current intensity data obtained is meaningful based on the obtained temperature information. If it is within the preset temperature range, the detection is considered normal and the obtained current intensity data is valid.

If the temperature information is not within the preset temperature range, the detection is considered abnormal and the obtained current intensity data is problematic. In this case, the mobile terminal can alert the patient that there is a problem with the blood glucose test and that a retest is necessary.
