Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to a real-time blood glucose monitoring device. Background Technology
[0002] Real-time blood glucose monitoring devices are an important tool in modern diabetes management. By continuously monitoring a patient's blood glucose levels, they help patients accurately manage their blood sugar and reduce the risk of complications. The sensor used to acquire the user's blood glucose levels in real time, along with the electronic components that send signals to the display device, are generally integrated into the monitoring unit. After implantation, the monitoring unit is attached to the target surface for continuous monitoring.
[0003] During the implantation process, the sensor is housed in a puncture needle and implanted into the user's body through the needle. However, in actual use, bleeding is often caused during implantation, which affects the accuracy of monitoring. After bleeding, the sensor needs to be removed for hemostasis, and it often needs to be discarded before monitoring can begin, causing certain economic losses to the patient.
[0004] Patent application CN119214646A discloses a real-time blood glucose monitoring device, including a housing with a receiving space and an installation port connecting the receiving space to the outside; a monitoring component disposed within the receiving space, including an electronic unit and a detection unit; a puncture component disposed within the receiving space, including a puncture member, a portion of which passes through the monitoring component to house a portion of the detection unit inside the puncture member; and a bottom cover detachably connected to the housing to close the installation port. The bottom cover has a mating wall disposed within the receiving space, and the mating wall has a first sealing element that seals against the bottom surface of the monitoring component to form a sealed cavity. A portion of the detection unit and a portion of the puncture member are disposed within the sealed cavity. The area enclosed by the first sealing element is smaller than the cross-sectional area of the sealed cavity. The cross-sectional area of the sealed cavity is larger than the area enclosed by the first sealing element, which, while ensuring a good seal, makes airtightness testing easier and improves test accuracy and precision.
[0005] However, the application still has some problems: although the application improves the stability and cleanliness of the structure by forming a sealed cavity, it is still inevitable that the blood vessels of the user will be punctured during use, causing bleeding and affecting the effect. At the same time, the puncture depth cannot be adjusted, which will also affect the data of subsequent monitoring. Summary of the Invention
[0006] In view of the problems existing in the prior art, this application is hereby filed.

[0037] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0038] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0039] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this application. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0040] Example 1
[0041] This is the first embodiment of the present application, which provides a real-time blood glucose monitoring device.
[0042] Specifically, refer to Figures 1-6 A real-time blood glucose monitoring device includes: a main component 100, including an applicator housing 101, a mounting housing 103 disposed inside the applicator housing 101, and an assembly housing 104.
[0043] The adjustment assembly 200 located on the inner wall of the mounting housing 103 includes a drive motor 201, an adjustment member located on the outer wall of the drive motor 201, a push rod 203 connected to the drive motor 201, a rotating cylinder 204 sleeved on the end of the push rod 203, and a drive member located on the end of the rotating cylinder 204.
[0044] The end of the patch housing 101 is also provided with a sensor pack 300 and the patch housing 301 is provided inside the sensor pack 300. The inner wall of the patch housing 301 is provided with a detection component for real-time monitoring of blood glucose data.
[0045] The adjusting component is used to adjust the position of the end of the push rod 203 on the inner wall of the rotating cylinder 204. The movement state of the rotating cylinder 204 is adjusted by the push rod 203. When the rotating cylinder 204 rotates due to the influence of the push rod 203, the position of the detection component inside the dressing shell 301 is adjusted by the rotating cylinder 204 to avoid blood vessels. When the push rod 203 does not drive the rotating cylinder 204 to rotate, the adjusting component adjusts the position of the push rod 203. The movement of the push rod 203 drives the driving component to move. The driving component is used to adjust the piercing depth when the detection component is fixed.
[0046] The mounting shell 103 and the assembly shell 104 are assembled together. The mounting shell 103 is engaged in the covering shell 1041 on the upper surface of the assembly shell 104. The first protrusion 1033 on the surface of the mounting shell 103 is engaged in the third groove 1042 on the surface of the covering shell 1041. The second groove 1032 around the first protrusion 1033 allows the first protrusion 1033 to move inward.
[0047] The applicator housing 301 is initially located inside the sensor package 300. By pressing the applicator housing 101, the applicator housing 301 is snapped into the bottom of the assembly housing 104. When snapped into place, the detection component inside the applicator housing 301 engages with the component inside the mounting housing 103. In the initial state, the mounting housing 103 is snapped into the inside of the applicator housing 101 through the first groove 1031 on its surface. When needed, the snapping state of the mounting housing 103 is released by pressing down the pressing button 102 inside the applicator housing 101. The push spring on the lower surface of the pressing button 102 pushes the mounting housing 103, causing the mounting housing 103 and the assembly housing 104 to move downward together. The applicator housing 301, which is fixed below the assembly housing 104, moves downward along with the assembly housing 104, ultimately causing the applicator housing 301 to adhere tightly to the human body.
[0048] As the mounting shell 103 and the assembly shell 104 move downwards, the first protrusion 1033 will abut against the inclined surface of the inner wall of the applicator housing 101. By squeezing, the first protrusion 1033 moves inward and disengages from the engagement of the third groove 1042. The second elastic element 208 inside the assembly shell 104 pushes the applicator shell 301 to separate from the assembly shell 104. The applicator shell 301 adheres tightly to the outside of the body, while the mounting shell 103 and the assembly shell 104 remain inside the applicator housing 101.
[0049] Before the button 102 is pressed, the applicator housing 101 is attached to the human body. Multiple miniature optical sensors at the bottom acquire blood vessel location information. Then, through the cooperation of the adjustment and driving components, the puncture angle of the detection component inside the applicator housing 301 is changed to reduce the risk of bleeding due to improper puncture position. At the same time, the pressure sensor detects the pressure of the detection component on the patient and adjusts the puncture depth to ensure the stability and accuracy of data acquisition.
[0050] Example 2
[0051] This is the second embodiment of the present application, which is implemented based on the previous embodiment.
[0052] Specifically, refer to Figure 5 and Figure 6 The push rod 203 is connected to the drive motor 201. The end of the push rod 203 extends to the inner wall of the rotating drum 204 and is provided with a gear ring 2035 at the end. The inner wall of the rotating drum 204 is provided with a drive ring 2043 and the drive ring 2043 is fixed to the outer wall of the rotating drum 204. The gear ring 2035 and the drive ring 2043 are engaged, and the rotating drum 204 is driven to rotate by the push rod 203.
[0053] The drive motor 201 is installed inside the mounting housing 103. The drive motor 201 drives the push rod 203 to rotate inside the mounting housing 103. A gear ring 2035 is installed at the bottom of the push rod 203 and is located inside the rotating drum 204. The rotating drum 204 is installed inside the mounting housing 103 and cannot be moved but can only rotate. A drive ring 2043 is fixed inside the end of the rotating drum 204 that is close to the gear ring 2035. The surface of the drive ring 2043 and the surface of the gear ring 2035 are engaged. In the initial state, the gear ring 2035 and the drive ring 2043 are engaged together. When the push rod 203 rotates, the gear ring 2035 drives the drive ring 2043 to rotate together, thereby driving the rotating drum 204 to rotate inside the mounting housing 103.
[0054] Preferred, refer to Figure 5 and Figure 6 The adjusting component includes a push cylinder 202, a push plate 2021 connected to the end of the push cylinder 202, an adjusting plate 2022 movably connected to the outer wall of the push plate 2021, and the end of the adjusting plate 2022 facing away from the push plate 2021 is connected to the outer wall of the push rod 203. The adjusting plate 2022 drives the end of the push rod 203 to move inside the rotating drum 204.
[0055] The electric cylinder 202 is fixed inside the mounting shell 103. The electric cylinder 202 pushes the push plate 2021 to move back and forth. A slide rail is opened on the surface of the push plate 2021. The straight column on the surface of the adjusting plate 2022 slides inside the slide rail. At the same time, the other end of the adjusting plate 2022 is connected to the concave part on the surface of the push rod 203. The adjusting plate 2022 is driven by the push plate 2021 with the central mounting position as the fulcrum, which drives the end connected to the surface of the push rod 203 to move, thereby driving the push rod 203 to change its position inside the mounting shell 103. When the position of the push rod 203 changes, the gear ring 2035 located at the bottom inside the rotating drum 204 moves, and the engagement state with the drive ring 2043 changes, thereby changing the state of the rotating drum 204.
[0056] Better, refer to Figures 4-6 and Figure 12A first drive gear 2041 is fixed to the outer wall of the rotating drum 204. The first drive gear 2041 meshes with a third drive gear 205 located on the end face of the assembly shell 104. An installation plate 302 is provided on the inner wall of the application shell 301, and a fifth drive gear 303 is provided on the end face of the installation plate 302. The fifth drive gear 303 extends to the outer wall of the application shell 301 and meshes with the third drive gear 205. A probe 304 is also provided on the inner wall of the installation plate 302 and extends to the outer wall of the application shell 301. When the third drive gear 205 rotates, the rotation of the fifth drive gear 303 causes the installation plate 302 to rotate on the inner wall of the application shell 301, changing the angle at which the probe 304 extends out of the outer wall of the application shell 301.
[0057] The third drive gear 205 is installed on the inner surface of the mounting shell 103 and meshes with the first drive gear 2041 on the surface of the rotating drum 204. When the gear ring 2035 and the drive ring 2043 are engaged, the rotating drum 204 and the push rod 203 rotate synchronously, and the third drive gear 205 rotates synchronously with the rotating drum 204. At the same time, the fifth drive gear 303 on the surface of the mounting plate 302 is located on the outside of the application shell 301 and meshes with the third drive gear 205. When the third drive gear 205 rotates, the fifth drive gear 303 rotates synchronously and drives the mounting plate 302 to rotate inside the application shell 301. The probe 304 is installed on the lower surface of the mounting plate 302 and is not on the same straight line as the axis of the fifth drive gear 303. When the fifth drive gear 303 rotates, the probe 304 deflects on the lower surface of the mounting plate 302, avoiding the original detection path through the deflection of the probe 304.
[0058] In summary, during use, the drive motor 201 drives the push rod 203 to rotate. The push cylinder 202 located on the side of the drive motor 201 pushes the push plate 2021 to move. The forward and backward movement of the push plate 2021 drives the adjusting plate 2022 to rotate around the fulcrum. When the push plate 2021 moves forward, the push rod 203 is affected and moves backward. When the push rod 203 moves backward, the gear ring 2035 at the end moves towards the drive ring 2043 and engages with the drive ring 2043. At this time, the rotation of the gear ring 2035 drives the drive ring 2043 to rotate. The drive ring 2043 is fixed together with the rotating drum 204, and the rotating drum 204 rotates synchronously with the push rod 203.
[0059] The first drive gear 2041 and the third drive gear 205 on one side of the rotating drum 204 mesh and drive the third drive gear 205 to rotate, as shown. Figure 4As shown, the third drive gear 205 meshes with the fifth drive gear 303 on the dressing shell 301. The dressing shell 301 is engaged below the assembly shell 104. When the third drive gear 205 rotates, it drives the fifth drive gear 303 to rotate. The mounting plate 302 located inside the dressing shell 301 rotates. The probe 304 on the lower surface of the mounting plate 302 deflects with the rotation, changing its original position and avoiding the location of blood vessels, thus avoiding bleeding and hematoma that may be caused by puncturing the vein.
[0060] Example 3
[0061] This is the third embodiment of the present application, which is implemented based on the previous embodiment.
[0062] Specifically, refer to Figures 4-6 The outer wall of the push rod 203 is hinged to a first push rod 2031, and the other end of the first push rod 2031 is hinged to a slider 2032. The outer wall of the push rod 203 is fitted with a straight plate 2033 and the slider 2032 is slidably disposed on the inner wall of the straight plate 2033. The outer wall of the push rod 203 is also fitted with a first elastic element 2034 and the first elastic element 2034 is located on the outer wall of the straight plate 2033.
[0063] Among them, such as Figure 6 As shown, the push rod 203 has a first push rod 2031 hinged to both sides, and the slider 2032 hinged to the other end of the first push rod 2031 is located inside the straight plate 2033. The first elastic member 2034 is located between the end of the push rod 203 and the straight plate 2033, controlling the distance between the straight plate 2033 and the end of the push rod 203.
[0064] When the gear ring 2035 at the end of the push rod 203 and the drive ring 2043 on the side of the rotating drum 204 are engaged together, the distance between the straight plate 2033 and the end of the push rod 203 is relatively far. At this time, the slider 2032 at the end of the first push rod 2031 is located near the center of the straight plate 2033.
[0065] Preferably, a second drive gear 2042 is movably disposed on the outer wall of the rotating drum 204, and a straight plate 2033 is located on the inner wall of the second drive gear 2042. The push rod 203 is moved by the adjusting plate 2022, and the slider 2032 at the end of the first push rod 2031 slides outward inside the straight plate 2033 and abuts against the inner wall of the second drive gear 2042. The push rod 203 drives the second drive gear 2042 to rotate on the outer wall of the rotating drum 204.
[0066] The second drive gear 2042 is movably disposed on the outside of the rotating drum 204, on the same side as the drive ring 2043 but not fixedly connected. The straight plate 2033 is located inside the second drive gear 2042. When the gear ring 2035 engages with the drive ring 2043, the sliders 2032 inside the straight plate 2033 move closer to each other. When the adjusting plate 2022 moves under the influence of the push cylinder 202, the adjusting plate 2022 drives the push rod 203 to move, and the push rod 203 moves towards the rotating drum 204. The gear ring 2035 at the end of the push rod 203 separates from the drive ring 2043. At the same time, the two sliders 2032 inside the straight plate 2033 are pushed by the first push rod 2031, slide towards both sides of the straight plate 2033 and abut against the inner wall of the second drive gear 2042, causing the second drive gear 2042 to rotate on the outer wall of the rotating drum 204.
[0067] Reference Figure 7 and Figure 8 The driving component includes an output gear 206, which meshes with a second driving gear 2042. A worm 2061 is provided at the shaft of the output gear 206, and the worm 2061 meshes with a worm wheel 2062 fixed to the inner wall of the mounting housing 103. The worm 2061 drives the worm wheel 2062 to rotate. A fourth driving gear 2063 is fixed to the outer wall of the worm wheel 2062, and the fourth driving gear 2063 rotates synchronously with the worm wheel 2062. A first rack 2064 meshes at the end of the fourth driving gear 2063, and a second rack 2065 is provided at the other end of the first rack 2064. The first rack 2064 moves due to the rotation of the fourth driving gear 2063, and the second rack 2065 drives the transmission gear 207 provided to the inner wall of the mounting housing 103 to rotate.
[0068] The output gear 206 meshes with the second drive gear 2042. When the second drive gear 2042 rotates, the output gear 206 drives the worm gear 2061 to rotate synchronously. The worm gear 2061 drives the worm wheel 2062, which is fixed to the inner wall of the mounting housing 103, to rotate. The fourth drive gear 2063, which is coaxially arranged on the outer wall of the worm wheel 2062, rotates together with the worm wheel 2062. The first rack 2064 and the second rack 2065 are connected together. The first rack 2064 is installed on the outside of the mounting housing 103 and can only move horizontally. It will not flip due to the rotation of the fourth drive gear 2063. The meshing of the fourth drive gear 2063 with the first rack 2064 drives the first rack 2064 to move horizontally. The second rack 2065 at the other end drives the transmission gear 207 to rotate synchronously with the fourth drive gear 2063 on the inner wall of the mounting housing 103.
[0069] Reference Figures 8-10The inner wall of the mounting housing 103 is also provided with a fixing sleeve 2073. A second bevel gear 2072 is movably arranged on the inner wall of the fixing sleeve 2073. The second bevel gear 2072 meshes with the first bevel gear 2071 arranged on the outer wall of the transmission gear 207. When the second bevel gear 2072 rotates, it drives the output shaft 2075 arranged on the inner wall of the fixing sleeve 2073 to move.
[0070] The fixing sleeve 2073 is fixed to the inner wall of the mounting shell 103, and the second bevel gear 2072 is installed in the middle position of the fixing sleeve 2073, such as... Figure 10 As shown, the second bevel gear 2072 is movably installed in the middle of the fixed sleeve 2073 and meshes with the first bevel gear 2071 on the outer wall of the transmission gear 207. The surface of the output shaft 2075 is threaded and engages with the thread on the inner wall of the second bevel gear 2072. When the second bevel gear 2072 rotates, it drives the output shaft 2075 to move up and down inside the fixed sleeve 2073.
[0071] The outer wall of the output shaft 2075 is provided with a sliding column 2076, and the end of the sliding column 2076 extends to the inner wall of the groove 2074 opened in the inner wall of the fixed sleeve 2073 and slides with it. The end of the output shaft 2075 away from the sliding column 2076 extends to the outer wall of the fixed sleeve 2073 and is provided with a connecting plate 2077 at the end. When the inner wall of the fixed sleeve 2073 is displaced, the output shaft 2075 drives the connecting plate 2077 at the end to move together.
[0072] Among them, the sliding column 2076 on the outer wall of the output shaft 2075 slides on the inner wall of the sliding groove 2074 opened on the inner wall of the fixed sleeve 2073. The fixed sleeve 2073 is fixed and cannot move. Therefore, when the output shaft 2075 is rotated by the second bevel gear 2072, it moves up and down inside the fixed sleeve 2073.
[0073] The connecting plate 2077 is located below the output shaft 2075 and connected to the output shaft 2075. It moves synchronously with the output shaft 2075 and moves below the fixed sleeve 2073.
[0074] Better, refer to Figure 10 and Figure 11 A rotating disk 2078 is movably provided on the inner wall of the connecting disk 2077, and a metal needle 2079 is fixed at the end of the rotating disk 2078. The metal needle 2079 is sleeved on the outer wall of the probe needle 304. The connecting disk 2077 drives the metal needle 2079 to move and change the length of the metal needle 2079 extending to the outer wall of the application shell 301.
[0075] Among them, such as Figure 10As shown, the connecting plate 2077 is sleeved on the outside of the rotating plate 2078. The rotating plate 2078 is not fixedly connected to the connecting plate 2077 and can rotate inside the connecting plate 2077. A metal needle 2079 is fixed below the rotating plate 2078. The metal needle 2079 adopts a U-shaped opening design and is also fixed off the axis of the rotating plate 2078, opposite to the initial position of the probe needle 304. When the applicator housing 101 is pressed into the sensor package 300, the metal needle 2079 penetrates the applicator housing 301 and wraps around the probe needle 304. It moves up and down inside the fixed sleeve 2073 through the output shaft 2075, changing the height of the connecting plate 2077 and the rotating plate 2078 below, thereby changing the insertion depth of the metal needle 2079.
[0076] When in use, the metal needle 2079 covers the probe 304 and is inserted into the human body to protect the probe 304. After the procedure, the metal needle 2079 is removed along with the housing 103, leaving the probe 304 inside the human body to monitor blood glucose levels in real time.
[0077] In summary, during use, a miniature optical sensor is used to acquire blood vessel location information. The engagement of the gear ring 2035 at the bottom of the push rod 203 with the drive ring 2043 causes the rotating drum 204 to rotate synchronously with the push rod 203. The first drive gear 2041 on the outside of the rotating drum 204 drives the third drive gear 205 to rotate, which in turn causes the fifth drive gear 303 on the surface of the dressing shell 301 to rotate. The rotation of the fifth drive gear 303 drives the mounting plate 302 and the probe needle 304 below to rotate. At this time, the metal needle 2079 covers the outside of the probe needle 304. The metal needle 2079 and the probe needle 304 are also eccentrically fixed. As the fifth drive gear 303 rotates, the metal needle 2079 covering the probe needle 304 deflects to avoid the blood vessel under the puncture site, thus avoiding blood vessel bleeding, hematoma formation, and affecting the accuracy of monitoring and the continuous use time of the device.
[0078] The pressure and depth of the metal needle 2079 insertion are detected by a pressure sensor. This, in turn, moves the adjusting plate 2022 via the electric cylinder 202, causing the push rod 203 to move towards the rotating drum 204. The gear ring 2035 separates from the drive ring 2043. The first push rod 2031, hinged to the surface of the push rod 203, pushes the slider 2032 to move laterally along the inner wall of the straight plate 2033, abutting against the inner wall of the second drive gear 2042. This drives the second drive gear 2042 to rotate. When the second drive gear 2042 rotates, the output gear 206 meshing with it drives the worm gear 2061 to rotate, which in turn drives the fourth drive gear on the surface of the worm gear 2062. The transmission between 2063 and the second rack 2065 drives the transmission gear 207 below the second rack 2065 to rotate. The first bevel gear 2071 on the surface of the transmission gear 207 meshes with the second bevel gear 2072, causing the second bevel gear 2072 to rotate inside the fixed sleeve 2073. When the second bevel gear 2072 rotates, the output shaft 2075 drives the connecting disk 2077 below to move and adjust the height below the fixed sleeve 2073. The connecting disk 2077 drives the rotating disk 2078 and the metal needle 2079 on the lower surface of the rotating disk 2078 to move, adjusting the length of the metal needle 2079 outside the probe needle 304 and adjusting the insertion depth.
