Description

Technical Field

[0001] The present invention relates to the technical field of blood glucose testing, and particularly to a dynamic non-invasive blood glucose testing device. Background Art

[0002] Diabetes has become the third chronic disease seriously endangering human health in the world after tumors and cardio-cerebrovascular diseases. The harm of diabetes lies in that the lack of sufficient nutrient supply to tissue cells in the human body for a long time will lead to various acute and chronic complications, and these complications will damage human organs, tissues, etc., and then affect the normal operation of the human body function. China's annual medical expenditure in the field of diabetes is 51 billion US dollars, ranking second in the world, second only to the United States' 320 billion US dollars, and China's direct medical expenditure on diabetes has accounted for 13% of China's medical expenditure. According to the results of the "Retrospective Analysis of Chronic Complications and Related Macrovascular Diseases in Inpatients with Diabetes Mellitus across the Country", the incidence rates of diabetes complications in China are as follows: hypertension 31.9%, cerebrovascular disease 12.2%, cardiovascular disease 15.9%, lower extremity vascular disease 5.0%, eye diseases 34.3%, kidney disease 33.6%, neuropathy 60.3%, and the total prevalence rate of diabetes complications is 73.2%. Generally speaking, among Chinese diabetes patients, one-third have hypertension, one-third have macrovascular diseases (including cerebrovascular and cardiovascular), one-third have eye diseases, and two-thirds have neuropathy.

[0003] The existing published number CN 114403863 A, named a dynamic non-invasive blood glucose testing device, includes a wristband, which is sleeved and fixed on the user's wrist; a sensing system, which is fixed on the wristband and is used for transmitting and receiving radio frequency signals and analyzing and processing them according to the radio frequency signals. The sensing system includes a display screen, a radio frequency unit, and a metamaterial sheet layer structure stacked in sequence from top to bottom. The metamaterial sheet layer structure is used for filtering other electromagnetic waves and only allowing the radio frequency signals emitted by the radio frequency unit to pass through; a radio frequency reflection module, which is fixed on the wristband and is symmetrically arranged with the sensing system, and is used for reflecting the radio frequency signals emitted by the sensing system. Overcoming the deficiencies of the prior art, this device can dynamically detect the blood glucose concentration value of the human body, and the injection of insulin will be precisely adjusted according to this value, so as to effectively control the blood glucose value within a safe range for a long time and further reduce the risk of complications.

[0004] Although the above device can dynamically detect the blood glucose concentration value of the human body, it is worn on the arm, and there will be a gap between it and the arm after it is worn.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 - 8, an embodiment provided by the present invention: a dynamic non-invasive blood glucose testing device, including a box body 1, a box cover 2, a display screen 5 and a detection probe 14. On one side of the top of the box body 1, two groups of bosses 10 are integrally injection-molded. A rotating seat 9 is rotatably arranged on the inner wall between the two groups of bosses 10. The rotating seat 9 is fixedly connected to the outer wall of one side of the box cover 2. The display screen 5 is fixedly installed at the center of the inner side wall of the box cover 2. Two groups of finger grooves 6 are symmetrically opened on the top surface of the box body 1. There are four groups of detection probes 14. Two groups of detection probes 14 are symmetrically arranged in each finger groove 6. The finger grooves 6 provided are used for placing fingers, so as to perform blood glucose testing. After the finger is placed in the finger groove 6, the detection probes 14 provided can detect both sides of the finger, detect the heat dissipated by the finger through the metabolic heat rash therapy, and calculate the blood glucose concentration through the obtained metabolic heat value, oxygen consumption and other information. That is, when non-invasive blood glucose testing is required, open the box cover 2, place the finger in the finger groove 6, and use the detection probes 14 provided to perform blood glucose testing on both sides of the finger, achieving the effect of non-invasive detection.

[0032] A button 13 is slidably arranged on the inner wall of the finger groove 6, and a sliding cavity 28 is opened on the inner wall of the box body 1 at the bottom side of the finger groove 6. A contact head 17 is fixedly installed at the center of the bottom of the button 13. A pressure sensor 18 is fixedly installed on the inner wall of the sliding cavity 28 at the bottom side of the contact head 17. The pressure sensor 18 is connected to the detection probe 14 through an electrical signal. After the finger is placed in the finger groove 6, press the button 13 with the finger. When the contact head 17 at the bottom of the button 13 touches the pressure sensor 18, the pressure sensor 18 can be triggered, and the electrical signal released by the pressure sensor 18 can activate the detection probe 14 to work. In this way, there is no need for manual switching. When blood glucose detection is required, just press the button 13 with the finger. Similarly, releasing the button 13 stops the detection.

[0033] A sliding groove is opened on the inner wall of the box body 1 between the finger groove 6 and the sliding cavity 28. A slider 19 is slidably arranged in the sliding groove. The slider 19 is fixedly connected to the outer wall of the button 13, and a first spring 20 is fixedly connected to the bottom of the slider 19. The bottom end of the first spring 20 is fixedly connected to the inner wall of the bottom side of the sliding groove. When the finger presses the button 13 to move, the sliders 19 on both sides of the button 13 sliding in the sliding groove can assist the button 13 to stably slide in the sliding cavity 28. After the finger releases the button 13, the elasticity of the first spring 20 provided can drive the button 13 to reset. At this time, the contact head 17 is separated from the pressure sensor 18, so as to achieve the effect of automatically stopping detection after use.

[0034] Two sets of pressure rods 26 are symmetrically installed at the bottom of the button 13. The bottom ends of the pressure rods 26 are connected to the detection probe 14 through a guiding component. The guiding component is arranged on the inner wall of the swinging groove 27. The swinging groove 27 is opened on the inner wall of the box body 1 on both sides of the pressure-sensitive element 18. When the button 13 moves, it drives the two sets of pressure rods 26 at the bottom to move. The arranged guiding component is used to convert the pressure received by the button 13 into a lateral force for the movement of the detection probe 14. Such a setting can drive the detection probes 14 on both sides to move simultaneously while pressing the button 13 to clamp both sides of the finger, so that the detection probe 14 can detect the blood glucose concentration more accurately.

[0035] The swinging groove 27 is composed of a vertical groove, an inclined groove and a horizontal groove. The vertical grooves are symmetrically opened on the inner wall of the box body 1 at the bottom side of the sliding cavity 28. The horizontal groove is opened on the inner wall of the box body 1 on one side of the detection probe 14. The upper and lower ends of the inclined groove are respectively connected to the horizontal groove and the bottom end of the vertical groove in a conducting manner, and the inclined groove is arranged obliquely. The arranged swinging groove 27 is used for the swinging of the guiding component. The arranged horizontal groove and vertical groove are respectively used for the sliding of the guiding rod 23 and the pressure rod 26. The arranged inclined groove is used for the swinging of the swinging rod 24.

[0036] The guiding component is composed of a swinging rod 24, a rotating rod 25 and a guiding rod 23. The middle part of the swinging rod 24 is rotationally arranged on the inner wall of the swinging groove 27 through the rotating rod 25, and the bottom end of the swinging rod 24 is rotationally connected to the bottom end of the pressure rod 26. The pressure rod 26 is slidably arranged on the inner wall of the vertical groove. The guiding rod 23 is slidably arranged on the inner wall of the horizontal groove, and one end of the guiding rod 23 is fixedly connected to the inner side wall of the detection probe 14. One side of the top end of the swinging rod 24 is attached to the other end of the guiding rod 23. When the pressure rod 26 moves downward driven by the button 13, it can drive the swinging rod 24 at the bottom to move downward. At the same time, there is a gap between the rotational connection of the pressure rod 26 and the swinging rod 24, leaving space for the relative displacement between the swinging rod 24 and the pressure rod 26 to avoid the generation of dead points and prevent the transmission between the two. When the bottom end of the swinging rod 24 swings downward, the swinging top end swings toward the button 13 side, so as to squeeze the guiding rod 23 on one side to move, and finally complete the effect that the detection probe 14 moves out for detection.

[0037] The detection probe 14 is slidably arranged on the inner wall of the guiding groove 15. The guiding groove 15 is connected to the horizontal groove in a conducting manner, and two sets of second springs 22 are symmetrically installed in the guiding groove 15. One end of the two sets of second springs 22 is fixedly connected to a guiding block 21. The guiding block 21 is fixedly connected to the outer walls on the upper and lower sides of the detection probe 14. When pressing the button 13 to drive the detection probe 14 to move out of the guiding groove 15 for use, it drives the second springs 22 to stretch at the same time. When the button 13 is released, the detection probe 14 can be driven to retract into the guiding groove 15 for storage through the resilience of the second springs 22. The sliding of the guiding block 21 in the guiding groove 15 can assist the detection probe 14 to move stably.

[0038] On the top surface of the box body 1, two groups of card slots 3 are symmetrically arranged. Magnets are fixedly installed on the inner walls of the two groups of card slots 3. On the inner side wall of the box cover 2, two groups of magnetic poles 4 are fixedly installed at positions corresponding to the two groups of card slots 3. When the device is not needed, the box cover 2 is covered, and the box cover 2 and the box body 1 are fixed by the attraction between the magnetic poles 4 on the box cover 2 and the magnets in the card slots 3.

[0039] On the inner wall of the front end face of the box body 1, a power supply slot is provided. A power supply seat 16 is clamped on the inner wall of the power supply slot. A card seat 11 is fixedly installed on one side wall of the power supply seat 16. The card seat 11 is in interference fit with the inner wall of the power supply slot, and a pulling slot 12 is provided on the outer side wall of the card seat 11. The power supply seat 16 can be fixed by the intimate fit between the card seat 11 and the power supply slot. The card seat 11 can be pulled out of the power supply slot through the provided pulling slot 12, so as to facilitate the replacement of the battery on the power supply seat 16.

[0040] On the inner wall of the top surface of the box body 1, an installation slot 7 is provided. A number of groups of indicator lights 8 are evenly installed on the inner wall of the installation slot 7. The indicator lights 8 are connected to the detection probe 14 through electrical signals. The provided indicator lights 8 can increase or decrease the number of illuminated indicator lights 8 according to the detection results of the detection probe 14 to prompt the detector.

[0041] Working principle: The finger grooves 6 are provided for placing fingers, so as to perform blood glucose testing. After the finger is placed in the finger groove 6, the detection probe 14 can detect both sides of the finger. The heat dissipated by the finger is detected through the metabolic heat rash therapy, and the blood glucose concentration is calculated based on the obtained metabolic heat value, oxygen consumption and other information. That is, when non-invasive blood glucose testing is required, the box cover 2 is opened, the finger is placed in the finger groove 6, and the detection probe 14 is used to test the blood glucose of both sides of the finger, achieving the effect of non-invasive detection. The indicator lights 8 can increase or decrease the number of illuminated indicator lights 8 according to the detection results of the detection probe 14 to prompt the detector. After the finger is placed in the finger groove 6, the button 13 is pressed by the finger. When the contact head 17 at the bottom of the button 13 touches the pressure sensor 18, the pressure sensor 18 can be triggered. The electrical signal released by the pressure sensor 18 can activate the detection probe 14 to work, so that there is no need to manually turn it on or off. When blood glucose detection is required, just press the button 13 with the finger. Similarly, when the button 13 is released, the detection stops. When the finger presses and moves the button 13, the sliders 19 on both sides of the button 13 slide in the chute to assist the button 13 to slide stably in the sliding cavity 28. After the finger releases the button 13, the elastic force of the first spring 20 drives the button 13 to reset. At this time, the contact head 17 disengages from the pressure sensor 18 to achieve the effect of automatically stopping detection after use. The guiding component is used to convert the pressure received by the button 13 into a lateral force for the movement of the detection probe 14. Such a setting can drive the two detection probes 14 to move simultaneously to clamp both sides of the finger while the button 13 is pressed, so that the detection probe 14 can detect the blood glucose concentration more accurately. When pressing the button 13 to drive the detection probe 14 out of the guide groove 15 for use, the second spring 22 is stretched at the same time. After the button 13 is released, the resilience of the second spring 22 drives the detection probe 14 to retract into the guide groove 15 for storage. The sliding of the guide block 21 in the guide groove 15 can assist the detection probe 14 to move stably. When the device is not needed, the box cover 2 is covered, and the box cover 2 and the box body 1 are fixed by the attraction between the magnetic pole 4 on the box cover 2 and the magnet in the card slot 3. The card holder 11 can be pulled out of the power supply slot through the provided pull groove 12, so as to facilitate the replacement of the battery on the power supply base 16.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
