Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an intelligent blood glucose monitoring device for gestational diabetes. Background Technology

[0002] Smart blood glucose monitoring devices for gestational diabetes transform the invisible and intangible physiological parameter of "blood glucose" into a sustainable, traceable, and interventionable "data stream," automatically making decisions or providing reminders for users at key points, thereby shifting the entire disease management from passive treatment to proactive prevention. In existing technology, patent publication number CN 220232266 U discloses a wearable smart health monitoring watch, including a casing. The upper part of the casing is equipped with a signal receiver and a display screen. A heat sink and a GPS locator are installed on the end face of the casing. The lower part of the casing has a bottom cover, and a mounting plate is installed on the lower part of the bottom cover. The mounting plate has a mounting groove on its lower part, and a piezoelectric thin-film sensor is installed inside the mounting groove. A mounting cover is fitted onto the side wall of the casing. Rubber gaskets are adhered to both sides of the mounting plate. Although the two sets of rubber gaskets can be connected by magnets during use, ... Magnets have weak shear resistance perpendicular to the adsorption direction (i.e., parallel to the skin surface). When the arm moves, the rubber pads can easily slip laterally due to friction, causing the magnets to misalign and the fixing effect to fail. When repairing the device inside the casing, the operator needs to rotate two sets of handwheels, and then the first wheel drives the lever to rotate. Finally, the casing is opened by the cooperation of the two sets of levers and the lever sleeve. This method is cumbersome and reduces the convenience of maintenance work. Therefore, we propose an intelligent blood glucose monitoring device for gestational diabetes. Summary of the Invention

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide an intelligent blood glucose monitoring device for gestational diabetes. Through the cooperative arrangement of a plate and a rod, two sets of fixation bandages can be connected and fixed, replacing the traditional method of connection via magnets. This solves the problem of bandages loosening due to accidental pulling of the magnets. Furthermore, the plate and rod will not misalign during subsequent arm movements, further improving the fixation effect. The cooperative arrangement of a locking block and a guide groove allows for the opening and closing of the protective plate. The entire process only requires adjusting the position of one adjustment plate, replacing the traditional method of assembling and disassembling the outer shell through the cooperation of two sets of levers and lever sleeves.

[0029] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-10This embodiment provides a technical solution: an intelligent blood glucose monitoring device for gestational diabetes mellitus, including a housing 1, a protective plate 2 hinged to the upper end of the housing 1, an enzyme electrode sensor 6 disposed in the middle of the bottom wall of the housing 1, and fixing straps 7 rotatably connected to the middle of both ends of the housing 1. The fixing straps 7 are made of spandex, which provides excellent elasticity, allowing the straps to fit tightly against the skin while ensuring comfort and not constricting the skin. The working electrode of the enzyme electrode sensor 6 comes into contact with glucose molecules in the interstitial fluid of the patient's subcutaneous tissue. The working electrode is an extremely thin and flexible electrode wire, usually made of platinum, gold, etc. Made of biocompatible material, the surface is covered with glucose-sensing enzyme. Then, glucose oxidase catalyzes the oxidation reaction of glucose to obtain hydrogen peroxide. At this time, the enzyme electrode sensor 6 applies a specific voltage to the working electrode, so that the hydrogen peroxide is further oxidized. Hydrogen peroxide oxidizes and generates electrons, which will form a weak current in the circuit. The magnitude of the current is proportional to the concentration of hydrogen peroxide, which is in turn proportional to the concentration of glucose. Therefore, the current intensity directly reflects the glucose level of the interstitial fluid. It also includes a connecting mechanism 8 and a fixing mechanism 9.

[0031] The connecting mechanism 8 includes a socket 81, a rod 85, a mounting base 86, a connecting base 87, and a drive plate 88. The socket 81 is located on the lower right side of the left-side fixing strap 7. The rod 85 is located on the right side inside the socket 81. The connecting base 87 is slidably connected in a groove opened in the middle of the bottom wall of the socket 81. The drive plate 88 is rotatably connected to the upper sides of both the front and rear ends of the connecting base 87. The mounting base 86 is rotatably connected to the opposite outer ends of the two sets of drive plates 88. During the movement of the connecting base 87, the drive plate 88 will push the mounting base 86, thereby causing the mounting base 86 to drive the rod 85 to move. Through the cooperation of the rod 85 and the plate 82, the two sets of fixing straps 7 can be connected and fixed, replacing the traditional method of connection by magnetic adsorption. This solves the problem of the fixing straps 7 becoming loose due to the magnet being accidentally pulled open. The rod 85 and the plate 82 will not be misaligned during subsequent arm movements, further improving the fixation effect.

[0032] Fixing mechanism 9: It is set inside the outer shell 1. Through the cooperation of the locking block 93 and the guide groove 94, it can control the opening or closing of the protective plate 2. The whole process can be completed by adjusting the position of an adjusting plate 95. It replaces the traditional method of installing and removing the outer shell 1 through the cooperation of two sets of levers and lever sleeves, which simplifies the operation process and further improves the convenience of use.

[0033] The outer casing 1 contains a controller 4, and the enzyme electrode sensor 6 is bidirectionally electrically connected to the controller 4, enabling the control of the electrical components inside the device.

[0034] The connecting mechanism 8 further includes a plug plate 82, a fixing rod 83, and a connecting plate 84. The plug plate 82 is located on the lower side of the left end of the right-side fixing strap 7. Slots are provided in the middle of both the front and rear ends of the plug plate 82. The fixing rod 83 is located on the right side of the front and rear walls of the socket 81. The connecting plate 84 is slidably connected to the middle of the outer arc surface of the fixing rod 83. Both sets of connecting plates 84 are slidably connected to the adjustment grooves provided on the right side of the bottom wall of the socket 81. The upper and lower sides of the relatively inner ends of the two sets of connecting plates 84 are respectively provided with… Insert rods 85 and mounting bases 86 are located on the upper and lower sides of the outer arc surface of vertically adjacent fixed rods 83, respectively. The two sets of insert rods 85 are installed in conjunction with the longitudinally adjacent slots. During the movement of the connecting base 87, a pulling force is applied to the mounting base 86 through the drive plate 88, thereby causing the mounting base 86 to drive the insert rods 85 to move through the connecting plate 84. At this time, the distance between the two sets of insert rods 85 will gradually decrease, and finally the two sets of insert rods 85 are inserted into the corresponding slots.

[0035] The fixing mechanism 9 includes a vertical plate 91, a push rod 92, a locking block 93, and a guide groove 94. The vertical plate 91 is located on the front side of the lower end of the protective plate 2. The push rod 92 is provided in the clearance groove in the middle of the front end of the vertical plate 91. The locking block 93 is provided on the rear side of the outer arc surface of the push rod 92. The front ends of the two sets of locking blocks 93 are in contact with the rear surface of the vertical plate 91. The guide groove 94 is provided on the upper and lower sides of the inner arc surface of the clearance groove. The push rod 92 will drive the locking block 93 to rotate. Then the reset component will drive the push rod 92 to move. The push rod 92 will move the locking block 93 forward. When the front end of the locking block 93 contacts the rear end of the vertical plate 91, the locking block 93 stops moving, thereby realizing the limiting and fixing of the protective plate 2.

[0036] The fixing mechanism 9 also includes an adjusting plate 95, a mounting cylinder 96, a guide groove 97, and a storage slot 98. The adjusting plate 95 is located on the front side of the outer arc surface of the push rod 92, and the right-side locking block 93 corresponds to the front and rear positions of the adjusting plate 95. The mounting cylinder 96 is located in the mounting slot opened in the middle of the front end of the outer casing 1. The middle and right sides of the outer arc surface of the mounting cylinder 96 are respectively provided with the guide groove 97 and the storage slot 98. The rear side of the outer arc surface of the mounting cylinder 96 is provided with a connecting slot. The guide groove 97 and the storage slot 98 are connected through the connecting slot. When the adjusting plate 95 is located inside the storage slot 98, the operator first pushes the adjusting plate 95, thereby driving... The adjusting plate 95 contacts the inner wall of the connecting groove, and then the operator rotates the adjusting plate 95. During the rotation, the adjusting plate 95 will also drive the locking block 93 to rotate through the push rod 92. When the adjusting plate 95 enters the interior of the guide slide 97 through the connecting groove, the locking block 93 is parallel to the guide slide 94. Then the adjusting plate 95 is released, and the tension generated by the contraction of the return spring 13 will drive the push rod 92 to move through the fixed plate 15. The push rod 92 will drive the locking block 93 to move, so that the locking block 93 passes through the guide slide 94. When the adjusting plate 95 contacts the front wall of the guide slide 97, the locking block 93 has separated from the guide slide 94.

[0037] Wherein: the front end of the push rod 92 is rotatably connected to the fixing plate 15, the front end of the mounting cylinder 96 is connected to the sealing plate 14 by bolts, and the rear end of the sealing plate 14 and the front end of the fixing plate 15 are provided with a return spring 13. The return spring 13 is located on the front side inside the mounting cylinder 96. The tension generated by the contraction of the return spring 13 will drive the push rod 92 to move through the fixing plate 15.

[0038] The upper part of the outer casing 1 is equipped with a control switch 3, and the rear side of the bottom wall of the outer casing 1 is equipped with a battery 5. The battery 5 is located on the left side of the controller 4. The input terminal of the control switch 3 is electrically connected to the output terminal of the battery 5, and the input terminal of the controller 4 is electrically connected to the output terminal of the control switch 3. The control switch 3 is adjusted to connect the circuit between the battery 7 and the controller 4. At this time, the power management chip inside the controller 4 will convert the unstable voltage of the battery 7 into an extremely stable and pure DC power to prevent voltage fluctuations from interfering with the sensitive blood glucose signal measurement.

[0039] Wherein: The lower left side of the socket 81 is connected to the mounting plate 10 by screws; the middle of the right wall of the slide is provided with a guide slide post 16; the middle of the outer arc surface of the guide slide post 16 is slidably connected to the connecting seat 87; the right end of the mounting plate 10 contacts the left end of the guide slide post 16; a spring 11 is provided between the right end of the mounting plate 10 and the left end of the connecting seat 87; the spring 11 is sleeved on the outside of the left side of the guide slide post 16; the tension generated by the contraction of the spring 11 will drive the connecting seat 87 to move and reset.

[0040] Wherein: The lower end of the connecting seat 87 is provided with a push plate 12. The operator pushes the push plate 12 with one hand, and the push plate 12 will drive the connecting seat 87 to move. The spring 11 extends, and the connecting seat 87 will give a push to the mounting seat 86 through the drive plate 88 during the movement, so that the mounting seat 86 drives the insertion rod 85 to move through the connecting plate 84.

[0041] The working principle of the intelligent blood glucose monitoring device for gestational diabetes provided by this invention is as follows: Before use, a family member of the patient should thoroughly clean and disinfect the selected installation site with an alcohol swab and allow it to air dry completely. For patients with gestational diabetes, the installation site is generally the back of the upper arm. After the installation site is dry, the family member should install a set of waterproof adhesive tape on the left and right sides of the lower end of the outer casing 1, then remove the factory protective film from the working electrode of the enzyme electrode sensor 6, and then insert the working electrode of the enzyme electrode sensor 6 into the skin of the patient's upper arm. Finally, It remains in the subcutaneous tissue. At this time, the lower surface of the outer shell 1 will contact the outer surface of the patient's upper arm through the waterproof adhesive. Then, the patient first presses the outer shell 1 with the protective plate 2, so that the outer shell 1 adheres to the patient's skin through the waterproof adhesive. Thus, the outer shell 1 is used to initially position the enzyme electrode sensor 6. Then, the patient's family member wraps the fixation bandage 7 around the patient's upper arm. Then, the patient's family member pushes the push plate 12 with one hand. The push plate 12 will drive the connecting seat 87 to move. The spring 11 extends. During the movement, the connecting seat 87 will provide power to the mounting seat through the drive plate 88. A thrust is applied to the mounting base 86, causing it to move the insertion rod 85 via the connecting plate 84. During this movement, the distance between the two sets of insertion rods 85 gradually increases. When the connecting plate 84 contacts the inner wall of the socket 81, the push plate 12 can no longer be pushed. Then, the insertion plate 82 is inserted into the socket 81, and the push plate 12 is released. At this point, the tension generated by the contraction of the spring 11 causes the connecting base 87 to move. During this movement, the connecting base 87 applies a pulling force to the mounting base 86 via the drive plate 88, causing the mounting base 86 to move the insertion rod 85 via the connecting plate 84. When the device moves, the distance between the two sets of plug rods 85 gradually decreases, and finally the two sets of plug rods 85 are inserted into the corresponding slots. When the connecting plate 84 contacts the outer surface of the plug plate 82, the connecting seat 87 stops moving, thereby realizing the installation of the intelligent blood glucose monitoring device for gestational diabetes. Subsequently, a protective cover can be set on the outside of the socket 81 to cover the push plate 12, thereby preventing accidental contact that could cause the connecting seat 87 to shift. The fixing strap 7 is made of spandex, which provides excellent elasticity, allowing the strap to fit snugly against the skin while ensuring comfort and not constricting the body.

[0042] In subsequent use of the intelligent blood glucose monitoring device for gestational diabetes, the patient controls switch 3 to activate the circuit between battery 7 and controller 4. At this time, the power management chip inside controller 4 converts the unstable voltage of battery 7 into extremely stable and pure direct current, preventing voltage fluctuations from interfering with the sensitive blood glucose signal measurement. Subsequently, through the control of controller 4, enzyme electrode sensor 6 begins operation. The working electrode of enzyme electrode sensor 6 contacts glucose molecules in the patient's subcutaneous interstitial fluid. The working electrode is an extremely thin and flexible electrode wire, usually made of biocompatible materials such as platinum and gold, with a surface covered with glucose-sensing enzyme. Glucose oxidase then catalyzes the oxidation of glucose to produce hydrogen peroxide. At this point, enzyme electrode sensor 6 applies a specific voltage to the working electrode, further oxidizing the hydrogen peroxide. The oxidation of hydrogen peroxide produces electrons, thus creating a weak current in the circuit. The current generated is directly proportional to the concentration of hydrogen peroxide, which in turn is directly proportional to the concentration of glucose. Therefore, the current intensity directly reflects the glucose level in the interstitial fluid. Finally, the enzyme electrode sensor 6 detects the intensity of this current through its internal components. The data detected by the enzyme electrode sensor 6 is then transmitted to the controller 4 through its built-in data transceiver module. The controller 4 receives the data sent by the enzyme electrode sensor 6 through its built-in serial communication port. Then, the user device (such as a smartphone) turns on Bluetooth and searches for nearby Bluetooth devices. The user selects the Bluetooth module on the controller 4 from the list of searched devices. The user device and the Bluetooth module on the controller 4 exchange pairing information, including device name, address, security key, etc. By exchanging the security key, the communication security between the devices is ensured. After pairing, a trust relationship is established between the devices, and data transmission can be performed. Finally, the controller 4 transmits the data to the user through its built-in Bluetooth module.

[0043] When it is necessary to replace the battery inside the casing 1 or to repair the internal equipment of the casing 1, the operator first pushes the adjusting plate 95, thereby causing the adjusting plate 95 to contact the inner wall of the connecting groove. Then, the operator rotates the adjusting plate 95. During the rotation, the adjusting plate 95 also drives the locking block 93 to rotate via the push rod 92. When the adjusting plate 95 enters the guide slide 97 through the connecting groove, the locking block 93 is parallel to the guide groove 94. After that, the adjusting plate 95 is released, and the tension generated by the contraction of the return spring 13 will drive the push rod 92 to move through the fixed plate 15. The push rod 92 will drive the locking block 93 to rotate. 3. Move the device so that the locking block 93 passes through the guide groove 94. When the adjusting plate 95 contacts the front wall of the guide slide 97, the locking block 93 has separated from the guide groove 94. Then, the operator drives the protective plate 2 to rotate through the latching groove on the front side of the upper end of the protective plate 2, thereby opening the protective plate 2. Then, the equipment inside the outer casing 1 can be inspected. After the inspection is completed, the operator rotates the protective plate 2, which will drive the upright plate 91 to rotate. When the upright plate 91 contacts the bottom wall of the outer casing 1, it means that the protective plate 2 is closed. Then, push the adjusting plate 95 backward, and the adjusting plate 95 will move along the guide slide 97 towards... After the adjustment plate 95 moves, the return spring 13 extends, and during the movement, the adjustment plate 95 moves the locking block 93 via the push rod 92. When the adjustment plate 95 contacts the inner wall of the connecting groove, the locking block 93 has passed through the guide groove 94 and extended to the rear side of the upright plate 91. Then, the adjustment plate 95 is rotated, and the adjustment plate 95 enters the storage groove 98 along the connecting groove. During the rotation of the adjustment plate 95, the locking block 93 rotates via the push rod 92. After the adjustment plate 95 is released, the tension generated by the contraction of the return spring 13 will move the push rod 92 via the fixed plate 15. The push rod 92 will then move the adjustment plate 95. The section plate 95 moves forward along the storage groove 98. At the same time, the push rod 92 also moves forward with the locking block 93. When the front end of the locking block 93 contacts the rear end of the upright plate 91, the locking block 93 stops moving, thereby limiting and fixing the protective plate 2. When the intelligent blood glucose monitoring device for gestational diabetes is not in use, the operator can remove the screws and bolts to separate the mounting plate 10 from the socket 81 and the sealing plate 14 from the mounting cylinder 96, thereby replacing the spring 11 and the return spring 13 to prevent the use effect from being affected by the decrease in the elasticity of the spring 11 and the return spring 13.

[0044] It is worth noting that the controller 4 disclosed in the above embodiments can be an ESP32-WROOM-32E-H4, the battery 5 can be a CR2032, and the enzyme electrode sensor 6 can be a FreeStyle Lite 3.
