Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of urine test strip detection, and particularly to a novel high-brightness uniform compensation mechanism for urine test strips. Background Technique
[0002] Urine analysis test strips are used to test bilirubin, urobilinogen, ketone bodies, ascorbic acid, glucose, protein (albumin), blood cells, pH, etc. in urine. Usually, during the detection process of urine test strips, the urine test strip is placed at the lower end of the detection device. After the detection device irradiates the outside of the urine test strip, the elements inside the urine test strip can be detected.
[0003] Most of the color detection devices of current urine analyzers on the market adopt the diagonal supplementary lighting method, that is, a set of symmetrically opposed supplementary light lamps are installed on both sides of the detector and directed towards the urine test strip to achieve the purpose of supplementary lighting. However, in the devices commonly used on the market, due to the easy deviation of the irradiation angles of the symmetrically opposed supplementary light lamps, the opposed angles are inconsistent, and then the supplementary light areas on the test paper are different in size, resulting in poor accuracy of the detection results. Therefore, we propose a novel high-brightness uniform compensation mechanism for urine test strips. Summary of the Invention
[0004] In view of the deficiencies of the existing novel high-brightness uniform compensation mechanism for urine test strips, the present invention provides a novel high-brightness uniform compensation mechanism for urine test strips, which has the advantages of driving light to irradiate from both sides inside the high-brightness supplementary lighting device through the high-brightness supplementary light lamp board, and then driving the light to be evenly dispersed through the high-brightness supplementary lighting device, ensuring the uniformity of supplementary lighting when the urine test strip placed on the upper part of the high-brightness supplementary lighting device is supplemented with light, and solving the problems raised in the above background technique.
[0005] The present invention provides the following technical solutions: A novel high-brightness uniform compensation mechanism for urine test strips, including a bracket, a high-brightness supplementary light lamp board is installed inside the bracket, a high-brightness supplementary lighting device is installed inside the high-brightness supplementary light lamp board, a clamping plate is placed on the upper part of the high-brightness supplementary lighting device, a limiting device is clamped inside the clamping plate, a urine test strip for limiting the clamping plate is installed on the side of the bracket, a linear guide rail is installed on one side of the bracket, a first slider is threadedly installed inside the linear guide rail through a first lead screw, a connecting frame is installed on the upper part of the first slider through a lifting lead screw, rotating the lifting lead screw controls the height of the connecting frame to be adjusted, a second slider is movably sleeved inside the connecting frame, and a color detector for detecting the urine test strip is installed at the lower end of the second slider.
[0006] Preferably, the high-brightness supplementary light lamp board includes a lamp bead bottom plate and LED lamp beads. The lamp bead bottom plate is installed inside the bracket, and the LED lamp beads are arranged at equal intervals inside the lamp bead bottom plate.
[0007] Preferably, the high-brightness supplementary lighting device includes a light source reflection film, a light source light guide plate, and a light source diffusion plate. The light source reflection film, the light source light guide plate, and the light source diffusion plate are stacked and installed in sequence, and the light source light guide plate is located in the middle of two groups of high-brightness supplementary light lamp boards.
[0008] Preferably, the clamping plate includes a first transparent glass and a second transparent glass. A cavity is formed between the first transparent glass and the second transparent glass, and the urine test strip is placed inside the cavity.
[0009] Preferably, the urine test strip includes a urine test strip substrate and urine test strips. The urine test strips are arranged at equal intervals on the upper part of the urine test strip substrate.
[0010] Preferably, the limiting device includes a clamping sleeve. The clamping sleeve is movably sleeved inside a limiting groove opened at the top of the bracket. At the same time, a pressing plate is installed on the clamping sleeve through a screw rod. The screw rod is threadedly connected to the pressing plate, and the pressing plate is fitted and installed on the upper part of the clamping plate.
[0011] Preferably, sliding grooves are opened on both sides of the clamping plate. Warning lights are movably sleeved inside the sliding grooves, and the warning lights are arranged at equal intervals inside the clamping plate.
[0012] Preferably, the first slider is horizontally installed on the side of the bracket, and the connecting frame is located directly above the clamping plate.
[0013] Preferably, a second lead screw for controlling the lateral movement of the second slider is installed on the upper part of the connecting frame. A set of lead screw stepping motors are installed on the sides of the first lead screw and the second lead screw.
[0014] Compared with the existing high-brightness uniform compensation mechanism, the present invention has the following beneficial effects:
[0015] 1. For this new high-brightness uniform compensation mechanism for urine test strips, the LED lamp beads evenly drive the light to be transmitted into the light source light guide plate. At the same time, the light source reflection film drives the light to be reflected upward, and the light source diffusion plate disperses the passing light, ensuring that the compensation light transmitted upward by the light source diffusion plate remains in a uniform state. The high-brightness supplementary lighting device is located at the bottom of the urine test strip. Therefore, the structure is simple, and the light source can illuminate the entire test strip, without different bright and dark areas, avoiding misjudgment of results caused by dark areas.
[0016] 2. The high-brightness uniform compensation mechanism of the new urine test strip is composed of a light source reflection film, a light source light guide plate, and a light source diffusion plate through a high-brightness light compensation device. The high-brightness light compensation device uses side light sources and irradiates the light guide plate and the diffusion plate. The brightness uniformity exceeds 90%. The high-brightness light source is evenly and effectively projected onto the urine test strip. Compared with the current technology, the structure is simplified, which is convenient for assembly and maintenance, and at the same time, the detection accuracy is improved.
[0017] 3. The high-brightness uniform compensation mechanism of the new urine test strip places the urine test strip inside the clamping plate. The position of the urine test strip is limited by the cavity formed inside the first transparent glass and the second transparent glass to ensure the neatness of the urine test strip and effectively avoid wrinkles in the placement of the urine test strip, which may cause dark spots during the irradiation of the compensation light, thus affecting the detection effect. At the same time, a warning light is installed outside the clamping plate. When the detection device detects an abnormality in the urine test strip block, the warning light at the corresponding position is activated, that is, after the detection is completed, the urine test strip blocks with problems can be screened out in a timely manner.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0026] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a high-brightness uniform compensation mechanism for a new type of urine test strip, including a bracket 1. Inside the bracket 1, a high-brightness supplementary light board 2 is installed. The high-brightness supplementary light board 2 evenly drives light to irradiate into the interior of the high-brightness supplementary light device 3. Inside the high-brightness supplementary light board 2, a high-brightness supplementary light device 3 is installed. The high-brightness supplementary light device 3 drives the light to spread evenly and performs light compensation processing on the urine test strip 6. A clamping plate 4 is placed on the upper part of the high-brightness supplementary light device 3. Inside the clamping plate 4, a limiting device 5 is clamped. The limiting device 5 is installed inside the bracket 1. At the same time, the limiting device 5 squeezes and limits the position of the clamping plate 4 at the upper end of the high-brightness supplementary light device 3. A urine test strip 6 for limiting the clamping plate 4 is installed on the side of the bracket 1. A linear guide rail 8 is installed on one side of the bracket 1. Inside the linear guide rail 8, a first slider 10 is installed by threading a first lead screw 9. The first lead screw 9 drives the first slider 10 to move horizontally, that is, to control the color detector 15 to contact the urine test strip 6 in turn. A connecting frame 12 is installed on the upper part of the first slider 10 through a lifting lead screw 11. Rotating the lifting lead screw 11 controls the height of the connecting frame 12 to be adjusted. Inside the connecting frame 12, a second slider 14 is movably sleeved. At the lower end of the second slider 14, a color detector 15 for detecting the urine test strip 6 is installed.
[0027] Please refer to Figure 4 , the high-brightness supplementary light board 2 includes a lamp bead bottom board 201 and LED lamp beads 202. The lamp bead bottom board 201 is installed inside the bracket 1. At the same time, the LED lamp beads 202 are arranged at equal intervals inside the lamp bead bottom board 201. The position of the LED lamp beads 202 is limited by the lamp bead bottom board 201. Starting the LED lamp beads 202, the LED lamp beads 202 evenly irradiate the light source inside the high-brightness supplementary light device 3, and the provided light source effectively performs light compensation processing during the detection of the urine test strip 6.
[0028] Please refer to Figure 4, the highlight supplementary lighting device 3 includes a light source reflection film 301, a light source light guide plate 302, and a light source diffusion plate 303. The light source reflection film 301, the light source light guide plate 302, and the light source diffusion plate 303 are sequentially stacked and installed. At the same time, the light source light guide plate 302 is located in the middle of two groups of highlight supplementary light lamp boards 2. By stacking the light source reflection film 301, the light source light guide plate 302, and the light source diffusion plate 303, the LED lamp beads 202 drive the light to irradiate inside the light source light guide plate 302. At the same time, through the divergence of the light source reflection film 301 and the light source diffusion plate 303, the highlight compensation light is made uniform, ensuring that when the light is transmitted to the inside of the urine test strip 6, the uniformity of light compensation is guaranteed.
[0029] Please refer to Figure 3 , the clamping plate 4 includes a first transparent glass 401 and a second transparent glass 402. A cavity is formed between the first transparent glass 401 and the second transparent glass 402. The urine test strip 6 is placed inside the cavity. By installing the first transparent glass 401 and the second transparent glass 402 on the inner side of the clamping plate 4, that is, installing the urine test strip 6 between the first transparent glass 401 and the second transparent glass 402, the stability of the urine test strip 6 during positioning is ensured. And after the first transparent glass 401 and the second transparent glass 402 press and limit the urine test strip 6, the flatness of the urine test strip 6 during positioning is ensured, avoiding wrinkles and warping when the urine test strip 6 is detected, which may cause dark spots after the light irradiates outside the urine test strip 6, thus affecting the detection effect of the urine test strip 6. At the same time, the clamping plate 4 is made of a highly transparent material, that is, to avoid the light being scattered after irradiating outside the clamping plate 4, which may affect the detection of the urine test strip 6.
[0030] Please refer to Figure 5 , the urine test strip 6 includes a urine test strip substrate 601 and urine test strips 602. The urine test strips 602 are arranged at equal intervals on the upper part of the urine test strip substrate 601. By installing the urine test strips 602 on the urine test strip substrate 601 for limitation, the stability of the urine test strips 602 is ensured when they are limited on the upper part of the urine test strip substrate 601.
[0031] Please refer to Figure 6, the limiting device 5 includes a jacket 501. The jacket 501 is movably sleeved inside the limiting groove opened at the top end of the bracket 1. At the same time, a pressing plate 503 is installed on the jacket 501 through a screw rod 502. The screw rod 502 is threadedly connected to the pressing plate 503. The pressing plate 503 is fitted and installed on the upper part of the clamping plate 4. After the urine test strip 6 is driven by the clamping plate 4 and installed on the upper part of the high-brightness light supplementing device 3, limiting devices 5 are installed on both sides of the clamping plate 4 at the same time. By inserting the jacket 501 into the inside of the bracket 1 and rotating the screw rod 502 at the same time, the screw rod 502 pushes the pressing plate 503 to move downward, that is, the pressing plate 503 presses both sides of the clamping plate 4 to ensure the stability of the clamping plate 4 positioned on the upper part of the high-brightness light supplementing device 3 and avoid air circulation, resulting in the position deviation of the urine test strip 6.
[0032] Please refer to Figure 2 , sliding grooves are opened on both sides of the clamping plate 4. Warning lights 7 are movably sleeved inside the sliding grooves. The warning lights 7 are arranged at equal intervals inside the clamping plate 4. By opening sliding grooves on the outside of the clamping plate 4, according to the different positions of the urine test strip blocks 602 inside the clamping plate 4, the corresponding warning lights 7 are controlled to be aligned with the urine test strip blocks 602, and the color detector 15 detects the urine test strip 6. When the urine test strip 6 is detected to be abnormal, the corresponding warning light 7 emits red light, which is convenient for the staff to screen out the problematic urine test strip blocks 602 subsequently.
[0033] Please refer to Figure 1 , the first slider 10 is horizontally installed on the side of the bracket 1. The connecting frame 12 is located directly above the clamping plate 4. By rotating the first lead screw 9, the first lead screw 9 controls the movement of the first slider 10 inside the linear guide 8, and then drives the color detector 15 to contact the urine test strips 6 at different positions, and at the same time controls the color detector 15 to detect the urine test strips 6 at the corresponding positions. At the same time, the lifting lead screw 11 is rotated, and the lifting lead screw 11 adjusts the height of the connecting frame 12, that is, the connecting frame 12 drives the distance between the color detector 15 and the urine test strip 6 to be adjusted.
[0034] Please refer to Figure 1 , a second lead screw 13 for controlling the lateral movement of the second slider 14 is installed on the upper part of the connecting frame 12. A set of lead screw stepping motors are installed on the sides of the first lead screw 9 and the second lead screw 13. By installing lead screw stepping motors on the outside of the first lead screw 9 and the second lead screw 13, starting the lead screw stepping motors can drive the first lead screw 9 and the second lead screw 13 to rotate, and at the same time adjust the left-right position and front-back position of the color detector 15 on the upper part of the bracket 1.
[0035] Working principle: When in use, install the urine test strip 6 inside the clamping plate 4. The position of the urine test strip 6 is limited by the first transparent glass 401 and the second transparent glass 402 to ensure that the urine test strip 6 remains flat during detection. At the same time, according to the different positions of the urine test strip block 602, a warning light 7 is installed outside the clamping plate 4, and the clamping plate 4 is placed on the upper part of the high-brightness light supplementing device 3. At the same time, limit devices 5 are installed on both sides of the bracket 1, and the limit devices 5 limit the position of the clamping plate 4 inside the high-brightness light supplementing device 3. When in use, start the LED lamp beads 202, and the LED lamp beads 202 drive the light to be transmitted into the light source light guide plate 302. Through the reflection of the light source reflection film 301 and the dispersion of the light source diffusion plate 303, it is ensured that the light is uniform when irradiating upward. At the same time, the light can uniformly irradiate upward from the lower part of the urine test strip 6. At the same time, start the lead screw stepper motor to adjust the position of the color detector 15, and the color detector 15 detects and processes the passing urine test strip 6.
[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
