Abstract
Description
Technical Field
[0001] This utility model relates to the field of blood glucose testing equipment technology, and in particular to a blood glucose meter. Background Technology
[0002] Blood glucose meters (GG meters) work primarily based on bioelectrochemical or optical technologies, obtaining blood glucose levels by measuring the glucose concentration in a blood sample.
[0003] Chinese utility model patent CN219016329U discloses a blood glucose meter, comprising a housing with a cavity consisting of an upper housing and a lower housing. A display module and a PCB circuit board are housed inside the cavity. The lower housing has a fixing groove, within which the display module is disposed. Multiple protrusions are provided around the fixing groove, and the PCB circuit board is positioned above the display module via these protrusions. A space is provided between the PCB circuit board and the display module. In this blood glucose meter, the PCB circuit board is no longer directly attached to the display module, and the space between them allows electronic components to be placed on the back of the PCB circuit board facing the display module, further improving the utilization rate of the PCB circuit board. Simultaneously, the space prevents heat accumulation between the PCB circuit board and the display module, improving heat dissipation and thus extending the overall lifespan of the device.
[0004] Although the aforementioned blood glucose meter uses the cavity between the upper and lower shells to house the PCB circuit board and display module, simplifying the integration of electronic components, the blood glucose testing process still requires auxiliary tools such as test strips and disposable needles. These still need to be stored separately when used outside, which is inconvenient. The single cavity structure also cannot meet the needs of modern daily life for compactness and portability. Therefore, we propose a blood glucose meter to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a blood glucose meter that can uniformly store the instruments used for blood glucose testing, such as circuits, display screen, test strips, and needles. The structure is more novel, compact and convenient, and easier to carry when going out.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a blood glucose meter, comprising: a first housing and a second housing, the top surface of the first housing having a first space recessed therein, and an integral irregular plate fixed on one side of the top surface, the irregular plate including at least one flange, and the flange smoothly connecting with the outer edge of the top surface of the first housing, the outer edge of the bottom surface of the second housing being magnetically fixed to the flange and the outer edge of the flange connecting to the top surface of the first housing, the interior of the second housing being hollowed out and sealed on the bottom surface by an assembly plate to form a second space, the first space being used to accommodate a needle and a test strip, the second space housing a PCB circuit board and a display screen electrically connected thereto, and an insertion port being provided on one side of the assembly plate for the test strip to be inserted and react with the PCB circuit board.
[0007] Furthermore, the irregular plate is an arc-shaped plate, and the corresponding curvature is consistent with the end of the first shell that is connected to it. The external shape structure formed by the top surface of the irregular plate and the top surface of the second shell is consistent with the external shape structure of the bottom surface of the first shell.
[0008] Furthermore, one end of the assembly plate near the flange is bent into an arc surface and a magnetic block is fixed inside the arc surface, while the other end has a detachable battery compartment.
[0009] Furthermore, both the needle and the test strip are multiple, and each needle is equipped with a matching blood collection sleeve.
[0010] Furthermore, a vertical partition is fixed to the inner wall of the first space, which is used to cooperate with the external soft pad to embed the needle.
[0011] Furthermore, all four sides of the first and second housings after magnetic assembly are smooth arc surfaces.
[0012] Compared with the prior art, the beneficial effects of this utility model include: In this solution, the first shell and the second shell are magnetically fixed, and the four sides of the whole are smooth arc surfaces, which can be held by the user with one hand. It is lightweight and reliable. The first space inside the first shell can accommodate the external needle and test strip. The second shell, through the built-in PCB circuit board and the display screen, realizes the detection of blood glucose concentration on the reaction layer of the test strip, and then converts the numerical value into blood glucose concentration by electrical signal. The user can directly observe it through the display screen, which is convenient, reliable and easy to carry. Attached Figure Description

[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0020] According to one embodiment of the present invention, in conjunction with Figures 1-4 As shown.
[0021] In this embodiment, a blood glucose meter includes a first housing 1 and a second housing 2. The top surface of the first housing 1 has a recessed first space 3, and an integral irregular plate 4 is fixed on one side of the top surface. The irregular plate 4 includes at least one flange 5, and the flange 5 is smoothly connected to the outer edge of the top surface of the first housing 1. The outer edge of the bottom surface of the second housing 2 is magnetically fixed to the flange 5 and the outer edge of the flange 5 connected to the top surface of the first housing 1. The interior of the second housing 2 is hollowed out and sealed on the bottom surface by an assembly plate 6 to form a second space 7. The first space 3 is used to accommodate a needle and a test strip. The second space 7 contains a PCB circuit board 8 and a display screen 9 electrically connected to it. An insertion port 10 is provided on one side of the assembly plate 6 for the test strip to be inserted and react with the PCB circuit board 8.
[0022] Specifically, the irregular plate 4 is an arc-shaped plate, and its corresponding curvature is consistent with the end of the first housing 1 that is connected to it. The external shape formed by the top surface of the irregular plate 4 and the top surface of the second housing 2 is consistent with the external shape of the bottom surface of the first housing 1. The assembly plate 6 is bent into an arc surface at one end near the flange 5 and a magnet 11 is fixed inside the arc surface. The other end has a detachable battery compartment.
[0023] Both the needles and the test strips comprise multiple units, and each needle is equipped with a matching blood collection sleeve. For the corresponding structure of the thimble, refer to the components disclosed in invention patent CN102813986A; details will not be repeated here, and actual implementation is not limited to this. In the actual assembly process, the needle can be placed using a partition 13 vertically fixed to the inner wall of the first space 3 in conjunction with an external soft pad.
[0024] Regarding the principle of blood glucose detection, the test strip contains a reaction reagent (such as glucose oxidase or dehydrogenase) at the tip. When a blood droplet comes into contact with the test strip, the glucose in the blood reacts with the reagent, and the generated hydrogen peroxide (H2O2) undergoes an oxidation reaction on the electrode to generate an electric current. The electrons generated by the reaction are transferred through the electrodes inside the test strip to form a tiny current. The blood glucose meter measures the current intensity, and the magnitude of the current is directly proportional to the glucose concentration. The blood glucose meter has a built-in calibration curve that converts the current signal into a blood glucose value (unit: mmol / L or mg / dL), and simultaneously displays the corresponding value on the display screen 9.
[0025] The first housing 1 and the second housing 2 in this application are magnetically assembled and have smooth curved surfaces on all four sides, allowing the user to hold them with one hand. They are lightweight and reliable. The first space 3 inside the first housing 1 can accommodate the external needle and test strip. The second housing 2, through the built-in PCB circuit board 8 and the display screen 9, can detect the blood glucose concentration of the blood on the reaction layer of the test strip and then convert the numerical value into blood glucose concentration using an electrical signal. The user can directly observe the concentration through the display screen 9, which is convenient, reliable, and easy to carry.
[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
