Technical Field
[0001] This invention relates to the field of medical device technology, specifically to a high-efficiency blood glucose detection device. Background Technology
[0002] Blood glucose testing is a core part of daily health management for diabetic patients. Currently, the mainstream blood glucose testing devices on the market are portable blood glucose meters. Users need to first insert a special blood glucose test strip into the test strip slot of the blood glucose meter so that the metal coating on the surface of the test strip forms an electrical connection with the conductive probe inside the blood glucose meter. Then, blood is dropped onto the reaction area of the test strip. The glucose oxidase in the reaction area reacts with the glucose in the blood to generate a tiny electrical signal. The electrical signal is transmitted to the signal processing module of the blood glucose meter through the conductive probe, and finally converted into a blood glucose concentration value and displayed. Most existing blood glucose meters use a straight-slot design for their test strip slots. Due to differences in user proficiency and hand stability, problems such as tilting, deviation, or insufficient insertion depth can easily occur when inserting the test strip. This can lead to insufficient contact and uneven force between the metal coating on the test strip surface and the conductive probe of the blood glucose meter, resulting in increased circuit contact resistance and unstable electrical signal transmission. Ultimately, this may affect the test results, causing data fluctuations or even test failure. Furthermore, during the insertion or removal of the test strip, the metal coating on the surface of the test strip will directly rub against the conductive probe inside the blood glucose meter slot. Long-term repeated friction will cause the metal coating to wear off and peel off, while also causing scratches and accelerated oxidation on the surface of the conductive probe. The conductivity of both will decrease significantly. The increased contact resistance between the worn metal coating and the conductive probe will weaken the electrical signal transmission efficiency, leading to lower or distorted test results. Severe wear may even cause a circuit break, directly resulting in test failure. This not only affects the user experience but also increases the user's operating costs due to premature damage to the test strip or blood glucose meter. In view of this, we propose a high-efficiency blood glucose detection device. Summary of the Invention
[0003] To address the aforementioned shortcomings of existing technologies, this invention provides a high-efficiency blood glucose detection device that effectively solves the problems of easy test strip insertion deviation, inaccurate positioning, and easy friction and wear between the metal coating and the conductive probe, which lead to unstable electrical signal transmission, deviation in detection results, or even detection failure, and also increase user costs.
[0004] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a high-efficiency blood glucose detection device, comprising a main unit including a housing, a test strip assembly disposed on the housing, a control and display assembly disposed on the housing, and a receiving assembly disposed on the housing, including... The auxiliary unit includes a clamping component disposed on the housing for clamping and fixing the test strip assembly, a moving component disposed on the housing for moving the fixed test strip assembly toward the receiving assembly, an opening and closing component disposed on the housing for opening and closing adjustment of the receiving assembly, and a laser sensor disposed on the housing for detecting whether the test strip assembly has been accurately moved to the designated position of the receiving assembly. The main unit also includes an inlet component disposed on the housing, which is used to prevent the test strip component from shifting during insertion.
[0005] Furthermore, the import component includes an import box fixedly connected to one side of the housing, and the inner wall of the import box is provided with a tapered guide groove for guiding the test strip component.
[0006] Furthermore, the test strip assembly includes a test strip body inserted into the inner wall of the inlet box, and a metal plating layer for electrical connection of the receiving assembly is fixedly connected to the surface of the test strip body.
[0007] Furthermore, the receiving component includes a probe holder fixedly connected to the inner wall of the housing, and two sets of elastic sheets fixedly connected to the probe holder near the inlet box. Each set of elastic sheets has a conductive probe sheet fixedly connected to the side of each set of elastic sheets that is close to each other, for electrical connection with the metal plating layer.
[0008] Furthermore, the moving component includes a motor fixedly connected to the inner wall of the housing, and a lead screw fixedly connected to the motor via an output shaft, with the end of the lead screw away from the motor rotatably connected to the inner wall of the housing.
[0009] Furthermore, the lead screw is threadedly connected to a fixing frame, and a guide rod is slidably connected to the inner wall of the fixing frame. Both ends of the guide rod are fixedly connected to the inner wall of the housing.
[0010] Furthermore, the clamping assembly includes two sets of bidirectional telescopic electric cylinders fixedly connected to the inner wall of the fixed frame. Each set of telescopic ends of the bidirectional telescopic electric cylinders is fixedly connected to a clamping plate for clamping and fixing the test paper body. The inner wall of the clamping plate is fixedly connected to an anti-slip soft pad.
[0011] Furthermore, the opening and closing assembly includes two sets of elastic plates that are fixedly connected to each other on one side away from each other. Fixed shafts are fixedly connected to both sides of the fixed plates. A connecting rod is rotatably connected to the end of the fixed shaft away from the fixed plates. A slider is rotatably connected to the end of the connecting rod away from the fixed shaft. A second guide rod is slidably connected to the inner wall of the slider. Both ends of the second guide rod are fixedly connected to the inner wall of the housing.
[0012] Furthermore, the opening and closing assembly also includes a one-way telescopic electric cylinder fixedly connected to the inner wall of the housing, with the telescopic end of the one-way telescopic electric cylinder fixedly connected to one side of the slider.
[0013] Furthermore, the control display assembly includes a display screen fixedly connected to the inner wall of the housing, and control buttons disposed on the top of the housing; The display screen is electrically connected to the power module and the display driver terminal of the MCU chip on the PCB board inside the housing, respectively, and is used to receive blood glucose concentration data and device status signals output by the MCU chip. The control button is electrically connected to the instruction input terminal of the MCU chip on the PCB board inside the housing, and is used to input operation instructions such as start detection and mode switching to the MCU chip.
[0014] The technical solution provided by this invention has the following advantages compared with known public technologies: This invention, through the setting of a guiding and positioning structure, provides precise guidance and initial positioning for the test strip insertion process, effectively avoiding tilting and offset during test strip insertion. The coordinated action of the clamping and moving components enables automatic and stable delivery and precise positioning of the test strip, eliminating the need for manual adjustment by the user. This reduces operational difficulty and reliance on manual intervention, making it particularly suitable for elderly patients and those with hand tremors. Combined with sensor detection and closed-loop control of the opening and closing structure, the conductive probe automatically closes and engages after the test strip is in place, ensuring a tight fit and uniform force between the metal plating and the conductive probe. This achieves a stable and reliable electrical signal transmission path, effectively improving the accuracy and consistency of test results, reducing the failure rate due to improper operation, and making operation more convenient and stable. By utilizing a linkage-controlled opening and closing structure, the conductive probe remains open during the translation of the test paper, avoiding direct frictional contact between the metal coating of the test paper and the conductive probe. This reduces wear and detachment of the metal coating and scratches and oxidation of the conductive probe, ensuring long-term stable conductivity of both components. This further extends the service life of the device and reduces operating costs. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0019] The present invention will be further described below with reference to embodiments.
[0020] like Figures 1 to 5As shown, a high-efficiency blood glucose testing device includes a main unit 100, comprising a housing 101, a test strip assembly 102 disposed on the housing 101, a control and display assembly 103 disposed on the housing 101, and a receiving assembly 105 disposed on the housing 101. An auxiliary unit 200 includes a clamping assembly 201 disposed on the housing 101 for clamping and fixing the test strip assembly 102, a moving assembly 202 disposed on the housing 101 for moving the fixed test strip assembly 102 towards the receiving assembly 105, an opening and closing assembly 203 disposed on the housing 101 for opening and closing adjustment of the receiving assembly 105, and a device disposed on the housing 101 for detecting whether the test strip assembly 102 has accurately moved to the designated position of the receiving assembly 105. The system includes a laser sensor 204, a main unit 100, and an introductory component 104 disposed on a housing 101. The introductory component 104 is used to prevent the test strip component 102 from shifting during insertion. The test strip component 102 is initially guided into insertion through the introductory component 104. A control and display component 103 is embedded on the surface of the housing 101 for human-machine interaction. A receiving component 105 is fixed to the inner wall of the housing 101 at the end of the moving path of the test strip component 102. A clamping component 201 of the auxiliary unit 200 is mounted on the moving component 202 and moves synchronously with the moving component 202. An opening and closing component 203 is linked to the receiving component 105. A laser sensor 204 is fixed to the inner wall of the housing 101 near the receiving component 105 for accurate detection of the position of the test strip component 102. Specifically, refer to Figures 2 to 5 The import component 104 includes an import box 1041 fixedly connected to one side of the housing 101. The inner wall of the import box 1041 is provided with a conical guide groove 1042 for guiding the test strip component 102. The test strip component 102 includes a test strip body 1021 inserted into the inner wall of the import box 1041. A metal plating layer 1022 for electrical connection to the receiving component 105 is fixedly connected to the surface of the test strip body 1021. The import box 1041 is fixedly connected to the opening on one side of the housing 101 by screws. The inner wall of the import box 1041 is integrally formed with a conical guide groove 1042. The large end of the conical guide groove 1042 faces the outside of the housing 101, and the small end faces the inside of the housing 101. The groove width gradually changes from the large end to the small end to match the width of the test strip body 1021. The material is wear-resistant ABS engineering plastic, and the surface is polished to reduce the insertion resistance of the test strip. It should be noted that the test strip assembly 102 consists of a test strip body 1021 and a metal plating layer 1022. The metal plating layer 1022 is fixed to the surface of the test strip body 1021 near the receiving assembly 105 using a vacuum sputtering process. The material is a highly conductive and oxidation-resistant gold plating layer. There are two sets of the metal plating layer, and the spacing corresponds one-to-one with the conductive probe pieces 1053 of the receiving assembly 105. When the test strip body 1021 is inserted, the front end is guided by the tapered guide groove 1042 and can accurately contact the end of the conductive probe piece 1053 in the receiving assembly 105 that is away from the probe seat 1051. At this time, the two sets of conductive probe pieces 1053 are in a naturally closed state and clamp the front end of the test strip body 1021 through their own elasticity to complete the initial positioning. Specifically, refer to Figures 2 to 4 The receiving component 105 includes a probe holder 1051 fixedly connected to the inner wall of the housing 101. Two sets of elastic sheets 1052 are fixedly connected to the probe holder 1051 near the inlet box 1041. Conductive probe sheets 1053 for electrical connection with the metal plating layer 1022 are fixedly connected to the sides of the two sets of elastic sheets 1052 that are close to each other. The moving component 202 includes a motor 2024 fixedly connected to the inner wall of the housing 101. A lead screw 2023 is fixedly connected to the motor 2024 through an output shaft. The lead screw 2023 is located away from the motor 2024. One end is rotatably connected to the inner wall of the housing 101. A fixing frame 2021 is threadedly connected to the surface of the lead screw 2023. A guide rod 2022 is slidably connected to the inner wall of the fixing frame 2021. Both ends of the guide rod 2022 are fixedly connected to the inner wall of the housing 101. The clamping assembly 201 includes two sets of bidirectional telescopic electric cylinders 2011 fixedly connected to the inner wall of the fixing frame 2021. Each set of telescopic ends of the bidirectional telescopic electric cylinders 2011 is fixedly connected to a clamping plate 2012 for clamping and fixing the test strip body 1021. The inner wall of the clamping plate 2012 is fixedly connected to the inner wall of the clamping plate 2012. The connection is equipped with an anti-slip soft pad 2013; the probe holder 1051 is fixedly connected to the inner wall of the housing 101 by a snap fastener. The probe holder 1051 is made of POM engineering plastic with excellent insulation properties. On the side near the inlet box 1041, two sets of elastic sheets 1052 are fixedly connected by injection molding. The elastic sheets 1052 are made of beryllium bronze and have good elastic recovery performance. On the side of each set of elastic sheets 1052 that are close to each other, a conductive probe sheet 1053 is fixedly attached by conductive adhesive. The tail of the conductive probe sheet 1053 is connected to the housing by a wire. The PCB board inside 101 is electrically connected. In the initial state, the two sets of elastic sheets 1052 are in a closed state under their own elasticity. The spacing of the conductive probe sheets 1053 is smaller than the width of the test strip body 1021, which can achieve contact positioning of the front end of the test strip. The motor 2024 is fixedly connected to the inner wall of the housing 101 through the motor 2024 bracket. The motor 2024 is a micro DC stepper motor 2024. The output shaft is fixedly connected to the lead screw 2023 through the coupling. The guide rod 2022 is used to ensure the smooth sliding of the fixing frame 2021. It should be noted that after the motor 2024 starts, the output shaft drives the lead screw 2023 to rotate. Through the threaded engagement between the lead screw 2023 and the fixed frame 2021, the rotational motion is converted into the linear motion of the fixed frame 2021. The guide rod 2022 restricts the rotational freedom of the fixed frame 2021, ensuring its smooth translation along the test paper movement direction, and driving the clamping assembly 201 and the test paper assembly 102 to move synchronously towards the receiving assembly 105. The clamping assembly 201 is assembled on the inner wall of the fixed frame 2021 of the moving assembly 202. Two sets of bidirectional telescopic electric cylinders 2011 are symmetrically fixed to both sides of the inner wall of the fixed frame 2021 by bolts. The bidirectional telescopic electric cylinders 2011 are miniature electric push rods, and the two telescopic ends are fixed by screws respectively. The test strip is connected to a clamping plate 2012. On the side of the two clamping plates 2012 that are close to each other, an anti-slip pad 2013 is glued and fixed. The anti-slip pad 2013 is made of silicone and has anti-slip texture on its surface to increase the friction with the test strip body 1021. After the test strip body 1021 is inserted by the inlet component 104 and completes the initial positioning, the bidirectional telescopic electric cylinder 2011 receives the instruction from the MCU chip and the telescopic end extends inward in sync, driving the two clamping plates 2012 to move closer to each other until the anti-slip pad 2013 is tightly attached to both sides of the test strip body 1021. The test strip body 1021 is clamped and fixed by friction, ensuring that the test strip will not loosen or shift, and avoiding excessive pressure that could cause the test strip to deform or the metal plating layer 1022 to be damaged. Specifically, refer to Figure 3 and Figure 5 The opening and closing assembly 203 includes two sets of elastic plates 1052, each fixedly connected to a fixed ear 2031 on one side away from the other. Fixed shafts 2032 are fixedly connected to both sides of each fixed ear 2031. A connecting rod 2033 is rotatably connected to the end of each fixed shaft 2032 away from the fixed ear 2031. A slider 2034 is rotatably connected to the end of each connecting rod 2033 away from the fixed shaft 2032. A guide rod 2035 is slidably connected to the inner wall of the slider 2034. Both ends of the guide rod 2035 are fixedly connected to the inner wall of the housing 101. The opening and closing assembly 203 also includes a single... The telescopic cylinder 2036 is a one-way telescopic cylinder. The telescopic end of the one-way telescopic cylinder 2036 is fixedly connected to one side of the slider 2034. The two sets of elastic plates 1052 are integrally formed with fixed ears 2031 on the opposite sides. The fixed ears 2031 are fixedly connected to fixed shafts 2032 on both sides by interference fit. The one-way telescopic cylinder 2036 is fixedly connected to the inner wall of the housing 101 by a bracket. The same model of miniature electric push rod as the two-way telescopic cylinder 2011 is selected. The telescopic end is fixedly connected to one side of the slider 2034 by screws. The tail is electrically connected to the drive module of the PCB board by wire. It should be noted that when the moving component 202 moves the test strip component 102 toward the receiving component 105, the one-way telescopic cylinder 2036 extends its telescopic end after receiving the command, pushing the slider 2034 to move along the guide rod 2035. The slider 2034 pulls the fixed shaft 2032 through the connecting rod 2033, causing the two sets of elastic sheets 1052 to open in a direction away from each other, thereby driving the two sets of conductive probe sheets 1053 to be in the open state, preventing the metal plating layer 1022 from contacting the conductive surface during the movement of the test strip. When the probe piece 1053 experiences frictional wear, and the laser sensor 204 detects that the test strip assembly 102 has reached the designated position, the telescopic end of the one-way telescopic cylinder 2036 retracts, pulling the slider 2034 to move in the opposite direction. The connecting rod 2033 pushes the fixed shaft 2032, and the two sets of elastic pieces 1052 approach each other under the action of their own elasticity and the thrust of the connecting rod 2033. The conductive probe piece 1053 closes and is tightly attached to the metal plating layer 1022 on the surface of the test strip body 1021, achieving a stable electrical connection. Specifically, refer to Figure 1 and Figure 2 The control display component 103 includes a display screen 1031 fixedly connected to the inner wall of the housing 101, and a control button 1032 disposed on the top of the housing 101. The display screen 1031 is electrically connected to the power module and the display driver terminal of the MCU chip on the PCB board inside the housing 101, respectively, for receiving blood glucose concentration data and device status signals output by the MCU chip. The control button 1032 is electrically connected to the instruction input terminal of the MCU chip on the PCB board inside the housing 101, for inputting operation instructions such as start detection and mode switching to the MCU chip. The display screen 1031 is embedded in a groove on the front of the housing 101, and can be used to... The FPC cable is electrically connected to the power module and MCU chip display driver of the PCB board inside the housing 101. The display screen 1031 is an OLED display screen 1031, which is used to receive blood glucose concentration data and device status signals output by the MCU chip, such as clamping status, movement status, connection status and operation prompt information. The control button 1032 is embedded in the button hole on the top of the housing 101 and is electrically connected to the MCU chip instruction input terminal of the PCB board through a metal spring. The control button 1032 is set as a touch button and is used to input operation instructions such as start detection, mode switching, and calibration confirmation to the MCU chip.
[0021] The working principle of this invention is as follows: Before the user starts the device, the device is in standby mode. The two sets of clamping plates 2012 of the clamping component 201 are in the open state. The opening and closing component 203 controls the two sets of conductive probe pieces 1053 of the receiving component 105 to naturally close under the elastic action of the elastic piece 1052. The laser sensor 204 is in real-time detection standby mode. The display screen 1031 displays the standby interface, waiting for user operation. When the user performs the test, he first inserts the rigid test strip body 1021 into the opening of the import box 1041 of the import component 104. The tapered guide groove 1042 on the inner wall of the import box 1041 adopts a gradient structure with the large end facing outward and the small end facing inward. Its guiding function can effectively correct the slight deviation when the test strip is inserted, ensuring that the test strip is smoothly pushed along the preset path. The insertion end of the test strip body 1021 is continuously pushed forward until it touches the end of the closed conductive probe piece 1053 that is away from the probe base 1051. At this time, the conductive probe piece 1053 slightly clamps the front end of the test strip by the elastic force of the elastic piece 1052, completing the initial positioning of the test strip. The user does not need to push it manually to avoid affecting the subsequent docking due to improper insertion depth. After the test strip completes its initial positioning, the user inputs a start detection command to the MCU chip by pressing the control button 1032 of the control display component 103. The MCU chip then sends a drive signal to the bidirectional telescopic electric cylinder 2011 of the clamping component 201. The two sets of telescopic ends of the bidirectional telescopic electric cylinder 2011 extend inward simultaneously, causing the two sets of clamping plates 2012 that are fixedly connected to move closer to each other until the anti-slip soft pad 2013 on the inner wall of the clamping plate 2012 is tightly attached to both sides of the test strip body 1021. The anti-slip soft pad 2013 is made of silicone and has anti-slip texture. It firmly fixes the test strip through friction, which not only prevents the test strip from loosening and shifting during subsequent movement, but also avoids excessive pressure that could cause the test strip to deform or damage the metal plating layer 1022 on the surface, thus ensuring the structural integrity and conductivity of the test strip. After the clamping assembly 201 completes the fixation of the test strip, the MCU chip synchronously starts the motor 2024 of the moving assembly 202. After the motor 2024 starts, the output shaft drives the lead screw 2023 to rotate through the coupling. By utilizing the threaded engagement between the lead screw 2023 and the fixing frame 2021, the rotational motion is converted into the linear motion of the fixing frame 2021. Under the limiting action of the guide rod 2022, the fixing frame 2021 smoothly moves towards the receiving assembly 105 along the axial direction of the guide rod 2022. Since the clamping assembly 201 is fixedly assembled on the inner wall of the fixing frame 2021, the test strip body 1021 moves synchronously towards the conductive probe sheet 1053 along with the fixing frame 2021. Before the movement, the MCU chip sends a drive signal to the one-way telescopic electric cylinder 2036 of the opening and closing component 203. The one-way telescopic electric cylinder 2036 pushes the slider 2034 to slide along the guide rod 2035. The slider 2034 pulls the fixed shaft 2032 on the fixed ear 2031 through the connecting rod 2033, thereby driving the two sets of elastic sheets 1052 to open in a direction away from each other. During the opening of the elastic sheet 1052, the conductive probe sheet 1053 fixedly connected to the inner side separates synchronously, forming a gap larger than the width of the test paper body 1021. This ensures that the metal plating layer 1022 on the surface of the test paper will not come into frictional contact with the conductive probe sheet 1053 during the translation process, fundamentally avoiding the decrease in conductivity caused by the wear of the metal plating layer 1022 and ensuring the stability of the subsequent electrical connection. When the moving component 202 moves the test strip body 1021 to the designated docking position of the receiving component 105, the end of the test strip body 1021 near the metal plating layer 1022 triggers the laser sensor 204. The laser sensor 204 is a distance detection type sensor, which immediately sends a detection signal that the test strip has arrived to the MCU chip. After receiving the signal, the MCU chip controls the motor 2024 of the moving component 202 to stop working, and the fixing frame 2021 and the test strip body 1021 stop moving. At this time, the metal plating layer 1022 on the surface of the test strip body 1021 is exactly aligned with the middle position of the two sets of conductive probe pieces 1053, and is in a precise docking posture. Subsequently, the MCU chip controls the retraction end of the one-way telescopic electric cylinder 2036 of the opening and closing component 203 to retract, the slider 2034 slides in the opposite direction along the guide rod 2035, the tension of the connecting rod 2033 on the fixed shaft 2032 disappears, and the two sets of elastic sheets 1052 close together in the direction of mutual approach under the action of their own elastic restoring force and the auxiliary thrust of the connecting rod 2033, driving the two sets of conductive probe sheets 1053 to approach each other synchronously until the conductive probe sheets 1053 are tightly attached to the metal plating layer 1022 on the surface of the test paper body 1021; Since the tail of the conductive probe 1053 is electrically connected to the PCB board inside the housing 101 via a wire, the metal plating layer 1022 of the test strip and the circuit system of the blood glucose meter form a stable electrical path. After the electrical path is established, the user adds blood to the reaction area of the test strip body 1021. The glucose oxidase in the reaction area reacts with the glucose in the blood to generate a tiny current signal proportional to the glucose concentration. This current signal is transmitted to the conductive probe 1053 through the metal plating layer 1022 on the surface of the test strip body 1021, and then to the signal processing module on the PCB board. The signal processing module amplifies and filters the tiny current signal and then transmits it to the MCU chip. The MCU chip converts the electrical signal into the corresponding blood glucose concentration value through its built-in algorithm. Finally, the MCU chip transmits the calculated blood glucose concentration data and device status information to the display screen 1031. The display screen 1031 displays the data visually for easy reading by the user. After the test is completed, the user can input the command to end the test via control button 1032. The MCU chip sequentially controls the extension of the one-way telescopic cylinder 2036 of the opening and closing component 203, the opening of the conductive probe piece 1053, and the reversal of the motor 2024 of the moving component 202, which drives the clamping component 201 and the test paper component 102 to move back. Then the bidirectional telescopic cylinder 2011 retracts, the clamping plate 2012 releases the test paper, and the user can pull out the used test paper component 102.
