Description

Technical Field

[0001] This utility model relates to the field of blood glucose monitoring equipment technology, and in particular to a dual-band magnetic non-invasive blood glucose monitor. Background Technology

[0002] Real-time blood glucose monitoring provides a basis for adjusting medication, diet, and exercise plans, ensuring blood glucose control targets are met, and helping people detect hyperglycemia or hypoglycemia promptly. In clinical practice, capturing the patterns of blood glucose fluctuations in different individuals enables precision medicine, improving treatment outcomes and quality of life.

[0003] Currently, there are two commonly used methods for blood glucose monitoring in clinical practice: one is the lancet method, which involves pricking the fingertip with a disposable lancet to collect a small amount of blood, and then using a blood glucose meter to measure the blood glucose level; the other is the patch method, which involves implanting a patch sensor under the skin to continuously monitor the glucose concentration in the interstitial fluid and transmit the data to a receiving device in real time. However, the lancet method requires frequent blood collection, which can cause pain, skin damage, and may lead to infection. Furthermore, each test only reflects a single point of blood glucose, failing to capture trends in blood glucose fluctuations, and consumes disposable needles, test strips, and other consumables, making continuous monitoring too costly. While the patch method eliminates the need for frequent lancet pricking, sensor implantation still requires a small incision, which may lead to skin redness, allergies, or infection. Additionally, the sensors and transmitters are expensive and require regular replacement, hindering large-scale application.

[0004] Therefore, developing non-invasive blood glucose monitoring methods can avoid the trauma of needle pricks or implanted sensors, reducing pain, skin damage, and the risk of infection. Furthermore, its convenient and real-time detection method can be integrated into everyday devices such as mobile phones and smartwatches, reducing reliance on hospitals or specialized equipment and facilitating home-based self-monitoring for daily blood glucose monitoring. It can also be combined with telemedicine platforms to improve the efficiency of chronic disease management. If non-invasive technology becomes widespread, it can shift blood glucose monitoring from "passive medical care" to "proactive health," aiding in early screening of high-risk groups for diabetes and basic blood glucose management in resource-scarce areas, thereby improving the overall accessibility of health monitoring.

[0005] Existing non-invasive blood glucose monitoring technologies include optical monitoring, photoacoustic monitoring, electrochemical monitoring, and electromagnetic and bioimpedance technology, among which optical non-invasive blood glucose monitoring technology is the most widely used. Optical technology achieves non-invasive blood glucose monitoring by capturing the characteristic optical signals (absorption, scattering, fluorescence) of glucose molecules in tissues. However, water molecules in tissues can also absorb these characteristic optical signals (earlobe tissue has a water content as high as 70%), so water molecules in tissues can interfere with blood glucose monitoring data. Statistics show that individual differences in water molecule content can lead to up to 20% deviation in blood glucose monitoring; therefore, the blood glucose monitoring data from existing technologies has a large deviation. Utility Model Content

[0006] Therefore, the technical problem to be solved by this utility model is to overcome the above-mentioned problems existing in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model provides a dual-band magnetic non-invasive blood glucose monitor, comprising: Two magnetic arms; A terminal component connects two magnetic arms; the terminal component is connected to one end of a magnetic arm.

The optical components include an infrared detector and an infrared emitter corresponding to the infrared detector. The infrared detector and the infrared emitter are respectively disposed in two connectors.

[0008] In one embodiment of this invention, the two optical components have different infrared light bands.

[0009] In one embodiment of this utility model, one of the two optical components has an infrared light band of 1200~1400nm and the other has an infrared light band of 1500~1700nm.

[0010] In one embodiment of this invention, the infrared detectors of the two optical components are located in the same connector.

[0011] In one embodiment of this utility model, the two connectors are magnetically attracted and fixed.

[0014] In one embodiment of the present invention, the terminal component includes a data transmission module and a signal processor disposed therein, the data transmission module being connected to the optical component and the signal processor being connected thereto.

[0015] In one embodiment of the present invention, the terminal component includes a display disposed on its outer wall, and the display is connected to a signal processor.

[0016] In one embodiment of this utility model, the application further includes a remote device electrically connected to the terminal component. In some embodiments, the terminal component is provided with a connection port for connection to the remote device.

[0017] In some other embodiments, the terminal component is wirelessly connected to the terminal device.

[0018] In one embodiment of the present invention, the terminal component further includes a battery module for power supply; the magnetic arm is provided with wires for connecting the battery module and the two optical components.

[0019] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art: The dual-band magnetic non-invasive blood glucose monitor of this invention can separately acquire the infrared light absorbed by water molecules in tissue and the total amount of infrared light absorbed by glucose molecules and water molecules in tissue.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0022] Reference Figures 1-6 As shown, this utility model embodiment provides a dual-band magnetic non-invasive blood glucose monitor, comprising: Two magnetic arms, 100; Terminal component 200 connects to two magnetic arms 100; terminal component 200 is connected to one end of magnetic arm 100. Two connectors 300 are connected face-to-face to the free ends of two magnetic arms 100; the two connectors 300 are clamped at the earlobe 500; Two optical components 400 are used to acquire infrared light absorbed by water molecules in the tissue and to acquire the total amount of infrared light absorbed by glucose molecules and water molecules in the tissue, respectively. The optical component 400 includes an infrared detector 410 and an infrared emitter 420 corresponding to the infrared detector 410. The infrared detector 410 and the infrared emitter 420 are respectively disposed in two connectors 300.

[0023] Specifically, this application can separately acquire the infrared light absorbed by water molecules in tissue and the total amount of infrared light absorbed by glucose and water molecules in tissue. Then, the infrared light absorbed by water molecules is removed from the infrared light absorbed by glucose and water molecules, thereby obtaining accurate infrared light absorbed by glucose molecules in tissue, thus improving the accuracy and precision of monitoring data. Furthermore, this application can be clipped onto the earlobe at a depth of 500mm, utilizing the thin skin of the earlobe for more precise blood glucose detection.

[0024] Furthermore, the two optical components 400 have different infrared wavelengths.

[0025] Furthermore, one of the two optical components 400 has an infrared wavelength of 1200-1400 nm, and the other has an infrared wavelength of 1500-1700 nm. The two optical components 400 are respectively a first optical component and a second optical component. The first optical component, with an infrared wavelength of 1500-1700 nm, is used to acquire the characteristic optical signals absorbed by glucose molecules in tissue. The second optical component, with an infrared wavelength of 1200-1400 nm, is used to acquire the characteristic optical signals absorbed by water molecules in tissue, as water molecules are particularly sensitive to infrared light in this wavelength range (1200-1400 nm).

[0026] Furthermore, the infrared detectors 410 of the two optical components 400 are located in the same connector 300. Specifically, this embodiment can reduce mutual interference between the two optical components 400, thereby improving the accuracy of the monitoring data. In another embodiment, the infrared detector 410 of one optical component 400 and the infrared emitter 420 of the other are located in the same connector 300.

[0027] Furthermore, the two connectors 300 are magnetically attached and fixed. In some embodiments, each of the two connectors 300 is provided with a magnet 310, and the magnets 310 of the two connectors 300 attract each other, thereby attaching the device to the earlobe 500. Specifically, this embodiment uses magnetic attraction to symmetrically clamp the two connectors 300 to the earlobe 500, thereby avoiding the need for precise alignment of the infrared detector 410 and infrared emitter 420 in the same optical component 400 when the device is clamped to the earlobe 500. This prevents misalignment of the two connectors 300 from causing signal interference between the two optical components 400, improving the accuracy and precision of the monitoring data. This application utilizes magnetic force to attach the optical component 400 to the earlobe for detection, taking advantage of the thin skin of the earlobe for more accurate blood glucose detection.

[0028] In some embodiments, the connector 300 is provided with a plurality (e.g., four) magnets 310 at equal intervals along its circumference.

[0029] Furthermore, the optical component 400 also includes a first one-sided transparent glass 430; the first one-sided transparent glass 430 and the infrared detector 410 are correspondingly disposed in the same connector 300, and the first one-sided transparent glass 430 is disposed on the side of the infrared detector 410 facing the infrared emitter 420. Specifically, the first one-sided transparent glass 430 can increase the amount of infrared light emitted by the infrared emitter 420 that is received by the infrared detector 410, thereby avoiding mutual interference between the two optical components 400 and thus improving the monitoring accuracy of this application.

[0030] Furthermore, the optical component 400 also includes a second one-sided transparent glass 440, which is disposed in the same connector 300 as the infrared emitter 420, and is located on the side of the infrared emitter 420 facing the infrared detector 410. Specifically, the function of the second one-sided transparent glass 440 corresponds to that of the first one-sided transparent glass 430, thereby further improving the monitoring accuracy.

[0031] Furthermore, the terminal component 200 includes a data transmission module 210 and a signal processor 220 disposed therein. The data transmission module 210 is connected to the optical component 400, and the data transmission module 210 is connected to the signal processor 220.

[0032] Furthermore, the terminal component 200 includes a display 230 disposed on its outer wall, and the display 230 is connected to the signal processor 220. Specifically, in this embodiment, signal transmission between the optical component 400 and the signal processor 220 is realized through the data transmission module 210. The signal processor 220 processes the received signals to obtain blood glucose monitoring data, and displays the blood glucose monitoring data on the display 230 in real time, so that the user can quickly know the monitoring value.

[0033] Furthermore, this application also includes a remote device electrically connected to the terminal component 200. In some embodiments, the terminal component 200 is provided with a connection port for connecting to the remote device. In some other embodiments, the terminal component 200 is wirelessly connected to the terminal device. Specifically, this embodiment can upload monitoring data to the remote device in real time, thereby recording, saving, and subsequently analyzing and comparing the data.

[0034] Furthermore, the terminal component 200 also includes a battery module 240 for power supply; the magnetic arm 100 is provided with wires for connecting the battery module 240 and the two optical components 400. Specifically, the terminal component 200 can supply power to the optical components 400 through the wires.

[0035] The terminal component 200 has power supply, data processing, data transmission, and data display functions. Internally, the terminal component 200 contains chips and circuits with data processing and transmission functions. It also has a built-in battery to power the internal circuits and chips, as well as the infrared light-emitting device. The terminal component 200 also includes a protective housing, a display 230, function buttons 250, and a connection port (e.g., a charging-data transmission integrated interface).

[0036] The principle of this application is as follows: Two connectors 300 are magnetically attached to both sides of the earlobe 500 being tested. The terminal assembly 200 supplies power to the optical assembly 400, causing the infrared emitter 420 to emit infrared light. The infrared detector 410 receives the infrared light emitted by the infrared emitter 420 after it penetrates the earlobe 500, and converts it into an electrical signal. This electrical signal is transmitted to the terminal assembly 200, which processes the received electrical signal and displays it on the display 230.

[0037] This application features a smaller size, lighter weight, lower cost, and more accurate test results. Furthermore, its lightweight and miniature design allows for continuous fixation to the earlobe for routine blood glucose monitoring. Blood glucose levels can be read directly from the display screen or connected to a remote device via a connector or Bluetooth for analysis.

[0038] This invention utilizes the extremely thin skin of the earlobe, rich in capillaries, allowing for more direct exchange of substances between interstitial fluid and blood, and a short dynamic lag time in glucose concentration. By employing a non-invasive blood glucose monitoring method at the earlobe, it significantly improves signal acquisition stability and response speed, thereby enhancing the accuracy of non-invasive blood glucose detection. This application allows for simple and quick detection of blood glucose concentration, as well as real-time monitoring of blood glucose levels, enabling both routine single-time testing and long-term blood glucose monitoring. This application can be used in scenarios such as hospitals and pharmacies providing blood glucose testing services; it can also be used in scenarios requiring continuous blood glucose monitoring, such as patient health monitoring and daily blood glucose monitoring. This application helps to integrate routine blood glucose monitoring into people's daily lives, making it easier for people to understand their own blood glucose levels in real time, thus meeting people's needs for monitoring their own health status.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
