Description

Technical Field

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

[0002] For existing blood glucose concentration detection means, blood needs to be drawn and detected twice a day on average, which brings great pain and inconvenience to patients. Finding a method that can detect blood components conveniently, continuously, effectively, accurately and non-invasively has been an ideal long-awaited by humans in the process of fighting diseases. A non-invasive blood glucose meter can measure blood glucose without a wound or using fingertip blood, which is undoubtedly great news for diabetic patients because they no longer need to prick their fingers. For non-invasive blood glucose detection, spectral technology is a commonly used technology in non-invasive blood glucose measurement. Among them, the spectral characteristics of glucose under near-infrared irradiation are the most obvious. Therefore, near-infrared light is usually used to measure the blood glucose content in the human body.

[0003] Currently, the most portable one is the watch-type non-invasive blood glucose meter. By designing it as a watch, it can be directly worn on the hand to achieve portable and continuous non-invasive blood glucose monitoring. However, during the use of this type of watch-type non-invasive blood glucose meter, since the main detection component needs to be closely attached to the skin, the strap part of this type of non-invasive blood glucose detector needs to be tightened and closely attached to the skin surface of the wrist.

[0004] However, there are two types of conventional watch straps: leather and metal. Among them, when adjusting the leather watch strap, the distance between two adjacent holes on the watch strap is taken as a unit, and when adjusting the length of the metal watch strap, the length of a single watch link is taken as a unit. Neither the metal watch strap nor the leather watch strap is flexible enough when adjusting the length. During the adjustment process of a unit length, it is extremely easy to cause the non-invasive blood glucose detector to be worn too tightly or too loosely on the hand. Being too tight will seriously affect the wearing comfort, and being too loose will cause the blood glucose monitoring main body not to be in close contact with the skin, which is likely to affect the detection accuracy. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that the non-invasive blood glucose detector mentioned in the above background art is worn too tightly or too loosely on the hand. Being too tight will seriously affect the wearing comfort, and being too loose will cause the blood glucose monitoring main body not to be in close contact with the skin, which is likely to affect the detection accuracy.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions: A portable non-invasive blood glucose detector, comprising: a housing, a fabric strap and a tightening device. A detection main body is installed on the housing. Fixed connecting block one and movable connecting block two are respectively installed at both ends of the housing. A chamber for the movement of connecting block two is provided on the housing. Connecting grooves are provided on both connecting block one and connecting block two. The fabric strap is an integrated fabric strap. Plug rods are fixedly connected to both ends of the fabric strap. Both of the plug rods are inserted into the corresponding connecting grooves. The tightening device is arranged in the chamber. The tightening device includes an adjusting rod for driving the movement of connecting block two.

[0007] Preferably, a support plate is fixedly connected in the chamber. The upper surface of connecting block two contacts the lower surface of the support plate. The lower surface of connecting block two contacts the bottom wall of the chamber. The adjusting rod is rotatably connected to the housing. Connecting block two can move stably.

[0008] Preferably, a moving groove is provided on the support plate. The tightening device further includes a plate body and connecting mechanisms arranged at both ends of the plate body. The adjusting rod is a threaded rod. The plate body is threadedly connected to the adjusting rod. The connecting mechanism includes a vertical plate. The vertical plate passes through the moving groove and is fixedly connected to connecting block two. The vertical plate is connected to the plate body through a horizontal plate. The tightness of the fabric strap is adjusted by the adjusting rod.

[0009] Preferably, an adjusting spring is arranged between the vertical plate and the plate body. Both ends of the adjusting spring are respectively fixedly connected to the plate body and the vertical plate. An adjusting component for separating the horizontal plate from the plate body is arranged on the support plate.

[0010] Preferably, a slot into which the end of the plate body is inserted is provided at one end of the horizontal plate. A slider is arranged at the other end of the horizontal plate. A sliding groove is provided on the vertical plate.

[0011] Preferably, the adjusting component includes a movable slide rail. The horizontal plate is slidably connected to the slide rail.

[0012] Preferably, an extension plate is fixed on the slide rail. A guide rod is fixedly connected to the extension plate. A restoring spring is sleeved on the guide rod. Both ends of the restoring spring are respectively connected to the support plate and the guide rod. The adjusting component can also adjust the tightness of the fabric strap.

[0013] Preferably, a synchronizing member is arranged between the two extension plates. The synchronizing member includes an adjusting wheel. A shaft rod is fixedly connected to the adjusting wheel. The adjusting wheel contacts one of the extension plates. The adjusting wheel is eccentrically connected to the shaft rod. The shaft rod is rotatably connected to the support plate.

[0014] Preferably, the synchronizing member further includes a gear and a rack. The shaft rod is fixedly connected to the gear. The gear meshes with the rack. One end of the rack is fixed to the other extension plate.

[0015] Preferably, locking components are provided on both the first connecting block and the second connecting block. The locking component includes a locking plate. Locking grooves into which the locking plate is inserted are provided at both ends of the insertion rod. A pressing plate is fixed on the locking plate, and a locking spring is connected to the locking plate. The synchronizing member enables the cross plates on both sides to move synchronously.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The tightness of the fabric watch band can be flexibly adjusted through the tightening device, avoiding the problems of being too tight or too loose during wearing caused by inflexible adjustment of conventional leather or metal watch bands. The fabric watch band can be tightened to make the detection body contact the skin, avoiding the problem that the detection body does not contact the skin tightly due to being too loose during wearing, which affects the detection accuracy and increases the detection accuracy. The adjustment methods are diverse and flexible: when the adjusting rod of the tightening device rotates, it can drive the second connecting block to move, thereby tightening the fabric watch band. The forward and reverse rotation of the motor can be controlled by the first button and the second button. The forward and reverse rotation of the motor through the adjusting rod can drive the second connecting block to move, thereby tightening and loosening the watch band. An adjusting component is also provided. When the tightening is excessive, the cross plate can be separated from the plate body by rotating the shaft rod, and the adjustment is made by using the elastic force of the adjusting spring. The adjustment methods are diverse and flexible. A restoring spring is provided. During the return process of the plate body, the cross plate can make the plate body snap into the slot under the action of the restoring spring, realizing the reconnection of the plate body and the cross plate. At the same time, it is also used for the restoration of components such as the adjusting wheel, shaft rod, extension plate, slide rail, and cross plate, ensuring the recoverability of the device structure and normal use.

[0036] Please refer to Figure 1 - Figure 13 , a portable non-invasive blood glucose detector, comprising: a housing 1, a fabric strap 2 and a tightening device 3. A detection main body 4 is installed on the housing 1. The detection main body 4 includes a housing, a display, a processor, a near-infrared spectroscopy module, a memory and a power module. The detection main body 4 emits near-infrared light into human tissue through the near-infrared spectroscopy module. Different blood glucose concentrations will cause changes in the absorption and scattering characteristics of light. The near-infrared spectroscopy module captures these changes to obtain blood glucose information, which is finally transmitted to the display through the data processor inside the detection main body 4. The detection main body 4 is a prior art and will not be introduced in detail.

[0037] Fixed connection blocks one 11 and movable connection blocks two 12 are respectively installed at both ends of the housing 1. A chamber 13 for the movement of the connection block two 12 is provided on the housing 1. Neither the connection block one 11 nor the connection block two 12 can be separated from the housing 1.

[0038] The fabric strap 2 is an integral fabric strap 2, which is made of materials such as nylon and polyester fiber. Plug rods 21 are fixedly connected to both ends of the fabric strap 2. Connection slots 14 are provided on both the connection block one 11 and the connection block two 12. Both plug rods 21 are inserted into the connection slots 14 at the corresponding ends. The connection slots 14 are arc-shaped. The arc-shaped connection slots 14 prevent the plug rods 21 from radially detaching. The housing 1 has a channel exposing the connection slots 14. The fabric strap 2 enters the chamber 13 through the channel to achieve the purpose of tightening.

[0039] Further, in order to increase the stability of the insertion rod 21, locking components 5 are provided on both the first connecting block 11 and the second connecting block 12. The locking component 5 includes a locking plate 51. Locking grooves 52 into which the locking plate 51 is inserted are provided at both ends of the insertion rod 21. A pressing plate 53 is fixed on the locking plate 51. The inner end of the locking plate 51 has an anti - detachment plate 56. The pressing plate 53 is fixed on the anti - detachment plate 56. A locking spring 54 is connected to the locking plate 51. Both the first connecting block 11 and the second connecting block 12 are provided with moving grooves 55. The locking spring 54 and the anti - detachment plate 56 are both located in the moving groove 55. The anti - detachment plate 56 contacts the arc - shaped wall of the moving groove 55. Both ends of the locking spring 54 are connected to the locking plate 51 and the inner wall of the moving groove 55 respectively. The locking plate 51 is inserted into the connecting groove 14. One end of the pressing plate 53 is inserted into the connecting groove 14 from the moving groove 55 and extends to the outside for convenient pressing. First, press the pressing plate 53, so that the locking plate 51 moves accordingly and the locking spring 54 is compressed. Then insert the insertion rod 21 into the connecting groove 14 and stop when the insertion rod 21 contacts the pressing plate 53. Release the pressing plate 53, and the locking spring 54 makes the locking plate 51 insert into the locking groove 52. A rod body passing through the anti - detachment plate 56 is provided in the moving groove 55, and the rod body keeps the locking plate 51 and the pressing plate 53 stable during the moving process. When removing the insertion rod 21, also press the pressing plate 53 first. When the locking plate 51 leaves the locking groove 52, pull out the insertion rod 21.

[0040] The tightening device 3 is arranged in the chamber 13. The tightening device 3 includes an adjusting rod 31 for driving the second connecting block 12 to move. The adjusting rod 31 makes the second connecting block 12 move. The second connecting block 12 drives the insertion rod 21 to move, and the movement of the insertion rod 21 tightens the fabric watch band 2, so that the detection main body 4 contacts the skin.

[0041] A support plate 15 is fixedly connected in the chamber 13. The upper surface of the second connecting block 12 contacts the lower surface of the support plate 15, and the lower surface of the second connecting block 12 contacts the bottom wall of the chamber 13, so that the second connecting block 12 can move stably. The adjusting rod 31 is rotatably connected to the housing 1.

[0042] A moving groove 16 is provided on the support plate 15. The tightening device 3 further includes a plate body 32 and connecting mechanisms 33 arranged at both ends of the plate body 32. The upper surface of the plate body 32 contacts the inner fixed wall in the chamber 13, and the lower surface of the plate body 32 contacts the support plate 15. A guide rod passing through the plate body 32 is fixedly connected in the chamber 13. The adjusting rod 31 is a threaded rod, and the plate body 32 is threadedly connected to the adjusting rod 31. The connecting mechanism 33 includes a vertical plate 331. The vertical plate 331 passes through the moving groove 16 and is fixedly connected to the second connecting block 12. Both side surfaces of the vertical plate 331 contact both side walls of the moving groove 16. The vertical plate 331 is connected to the plate body 32 through a cross - plate 332. When the adjusting rod 31 rotates, the plate body 32 drives the cross - plate 332, the vertical plate 331 and the second connecting block 12 to move, thereby tightening the fabric watch band 2.

[0043] Further, a motor 34 and a battery pack 35 are arranged on the support plate 15. The output end of the motor 34 is fixedly connected to the adjusting rod 31. There is a charging interface for the battery pack 35 on the housing 1, which is not shown in the figure. A controller 36 and wires are arranged in the cavity. The controller 36 is located on the support plate 15. The controller 36 is equipped with a relay by itself. The wires are used to connect each electronic component to form a complete circuit path to ensure that current can be normally transmitted between each component. A button one 361 and a button two 362 are arranged on the housing 1. The button one 361 controls the forward rotation of the motor 34, and the button two 362 controls the reverse rotation of the motor 34. Through the above components, when the button one 361 or the button two 362 is pressed and not released, the motor 34 rotates forward or reverses continuously. When the button one 361 or the button two 362 is released, the motor 34 stops rotating.

[0044] Further, an adjusting spring 37 is arranged between the vertical plate 331 and the plate body 32. The two ends of the adjusting spring 37 are respectively fixedly connected to the plate body 32 and the vertical plate 331. An adjusting component 38 for separating the cross plate 332 from the plate body 32 is arranged on the support plate 15. In order to prevent the fabric watch band 2 from being tightened too much, the cross plate 332 is separated from the plate body 32 through the adjusting component 38. The vertical plate 331 is subjected to the pulling force of the fabric watch band 2, the vertical plate 331 moves away from the plate body 32, and the cross plate 332 moves along with the vertical plate 331.

[0045] One end of the cross plate 332 is provided with a slot 333 into which the end of the plate body 32 is inserted. The other end of the cross plate 332 is provided with a slider 334. A chute 335 is opened on the vertical plate 331. The slider 334 passes through the chute 335, and the slider 334 has an anti - detachment part. The adjusting component 38 includes a movable slide rail 381. The cross plate 332 is slidably connected to the slide rail 381, and the cross plate 332 can be separated from the plate body 32 at any position. A first inclined surface 336 is opened on the cross plate 332, and a second inclined surface 321 is opened on the plate body 32.

[0046] An extension plate 382 is fixed on the slide rail 381. A guide rod 383 is fixedly connected to the extension plate 382. A restoring spring 384 is sleeved on the guide rod 383. The two ends of the restoring spring 384 are respectively connected to the support plate 15 and the guide rod 383. The restoring spring 384 is arranged. During the return process of the plate body 32, when the first inclined surface 336 contacts the second inclined surface 321, the cross plate 332 can make the plate body 32 snap into the slot 333 under the action of the restoring spring 384, realizing the re - connection of the plate body 32 and the cross plate 332. At the same time, it is also used for the restoration of components such as the adjusting wheel 391, the shaft rod 392, the extension plate 382, the slide rail 381, and the cross plate 332, ensuring the recoverability of the device structure and normal use.

[0047] A synchronizing member 39 is arranged between the two extension plates 382. The synchronizing member 39 includes an adjusting wheel 391. A shaft rod 392 is fixedly connected to the adjusting wheel 391. The adjusting wheel 391 contacts one of the extension plates 382. The adjusting wheel 391 is eccentrically connected to the shaft rod 392. One end of the shaft rod 392 extends to the outside of the housing 1, and the shaft rod 392 is rotatably connected to the support plate 15.

[0048] The synchronizing member 39 further includes a gear 393 and a rack 394. The support plate 15 is provided with a protruding plate for limiting the rack 394. The upper surface of the rack 394 contacts the top surface of the chamber 13. The shaft rod 392 is fixedly connected to the gear 393. The gear 393 meshes with the rack 394. One end of the rack 394 is fixed to the other extension plate 382. By means of the adjusting wheel 391, the shaft rod 392, the gear 393 and the rack 394, the two extension plates 382 move closer to or away from each other simultaneously.

[0049] When it is necessary to tighten the fabric watch band 2, press the first button 361, so that the motor 34 rotates forward. The motor 34 causes the plate body 32 to move into the chamber 13. The plate body 32 drives the cross plate 332, the vertical plate 331, the adjusting spring 37, the second connecting block 12 and the inserting rod 21 to move together. The second connecting block 12 drives the inserting rod 21 to move under the support plate 15, so as to tighten the fabric watch band 2. After the fabric watch band 2 is tightened, release the first button 361. At this time, the detection body 4 contacts the skin, increasing the detection accuracy.

[0050] If the tightening is excessive, firstly, the motor 34 can be rotated in reverse by pressing the second button 362, and the plate body 32 returns. The cross plate 332, the vertical plate 331, the adjusting spring 37, the second connecting block 12 and the inserting rod 21 return together, so as to achieve the purpose of comfortable wearing. Secondly, by rotating the shaft rod 392, the shaft rod 392 causes the adjusting wheel 391 and the gear 393 to rotate simultaneously. The adjusting wheel 391 causes one of the extension plates 382 to move. The gear 393 causes the rack 394 to move. The rack 394 causes the other extension plate 382 to move. The two extension plates 382 move away from each other. The extension plates 382 drive the guide rod 383, the slide rail 381, the cross plate 332 and the slider 334 to move. The cross plate 332 is separated from the plate body 32. The vertical plate 331 is subjected to the pulling force of the fabric watch band 2. The two vertical plates 331 are away from the plate body 32. The vertical plate 331 drives the cross plate 332 to move through the slider 334. The cross plate 332 slides on the slide rail 381, and the adjusting spring 37 is stretched. The elastic force of the adjusting spring 37 is used to achieve the purpose of comfortable wearing. Further, when the cross plate 332 is separated from the plate body 32, the plate body 32 can also be moved by the forward and reverse rotation of the motor 34, so as to adjust the elastic force of the adjusting spring 37.

[0051] The reconnection of the plate body 32 and the cross plate 332 is achieved by reversing the motor 34 through the second button 362. During the return process of the plate body 32, when the second inclined surface 321 contacts the first inclined surface 336, the cross plate 332 moves. The cross plates 332, slide rails 381, extension plates 382, and guide rods 383 on both sides, together with the sliders 334, move simultaneously, compressing the restoring spring 384. When the plate body 32 contacts the inner wall of the slot 333, the cross plate 332, under the action of the restoring spring 384, causes the plate body 32 to be inserted into the slot 333.

[0052] In some embodiments, diabetes can be screened through breath. Specifically, a breath through-hole is provided on the upper surface of the detection body 4. During detection, other components such as the measurement light source, photodetector, and computer system of the breath acetone measurement device of the detection body 4 are turned on. The breath acetone detector is asked to maintain a breath state facing the breath through-hole, and the exhaled breath from deep within the lungs, that is, the breath sample gas, enters the breath through-hole. Then, the measurement beam generated by the measurement light source is focused by a lens, and the measurement light is guided into the hollow optical fiber tube by an optical fiber. The measurement light passes through the breath sample gas in the hollow optical fiber tube and is transmitted out, and then is focused by a lens and conducted to the photodetector by an optical fiber. The photodetector detects the absorption spectrum signal of the breath sample gas. The photodetector transmits the detected absorption spectrum signal of the breath sample gas to the computer system. The computer system compares the detected absorption spectrum data signal with the absorption spectrum data signal of the acetone-containing mixed gas with a known acetone concentration that was previously measured and stored in the computer memory to obtain the acetone content in the breath sample gas, and further determines whether a person has diabetes. The accuracy of breath screening is 90%.
