Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of urine test strip processing, and particularly to a novel urine test strip screening device. Background Art
[0002] A urine test strip refers to a test paper for testing bilirubin, urobilinogen, ketone bodies, ascorbic acid, glucose, protein (albumin), blood cells, pH, etc. in urine. After collecting urine, the urine test strip is further detected by a urine analyzer.
[0003] Currently, most urine analyzers on the market use manual placement of urine test strips or a drum-structured automatic screening device. When using manual placement of urine test strips, the steps are rather cumbersome, resulting in time-consuming during the detection process of urine test strips. When using a drum-structured automatic screening device, it is easy for the test strip to be difficult to fit exactly into the groove, thus affecting the screening speed. At the same time, the gap when rolling out is likely to catch and damage the color patches on the test strip. Moreover, since the test strip is prone to chemical reactions with water vapor in the air, it needs to be stored in a dry environment. However, in reality, most instruments use desiccants for storage, which have a time limit and slow drying effect. Summary of the Invention

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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.
[0030] Please refer to Figure 1 、 Figure 4 and Figure 6, the present invention provides a technical solution: a novel urine test strip screening device, which includes a bracket structure 1 and a urine test strip 4. Inside the bracket structure 1, there is a scraper screening device 2 for transporting the urine test strip 4. The scraper screening device 2 includes an entire drive system, mainly used to extract the urine test strip 4 from the test strip magazine 101. On the right side of the scraper screening device 2, there is a direction adjustment device 3 for adjusting the front and back directions of the urine test strip 4. The direction adjustment device 3 includes an entire drive system, mainly used to adjust the front and back directions of the urine test strip 4. A color detector 5 for detecting the front and back sides of the urine test strip 4 is fixedly installed on the bracket structure 1. The color detector 5 is used to judge the front and back directions of the urine test strip 4. The side with a colored block is the front. On the right side of the direction adjustment device 3, there is a conveying device 6, which is used to convey the corrected urine test strip 4 to other places for subsequent detection. On the right side of the conveying device 6, there is a discharge plate 14 fixedly installed. On the left side of the bracket structure 1, there is a heating device 7 pasted. The heating device 7 can adopt a single-sided adhesive heating film, which is pasted on the inclined wall of the bracket structure 1 to provide a constant temperature heating of 30° for evaporating the water vapor in the bracket structure 1 to ensure a dry environment all the time, improve the storage environment of the urine test strip 4. On the front and back sides above the conveying device 6, there are rollers 23 for limiting the urine test strip 4 respectively. On the upper end of the roller 23, there is a side plate 8. On the outside of the side plate 8, there is a telescopic rod 9 fixedly connected. On the outer wall of the telescopic rod 9, there is a sleeve rod 10 movably sleeved. Inside the telescopic rod 9, there is a moving component 11.
[0031] The bracket structure 1 includes a test strip magazine 101, a sheet metal sliding surface 102 and a fixed support 103. The fixed support 103 is used to support the urine test strip 4. It is a fixed part, a non-moving part. The left end of the sheet metal sliding surface 102 is fixedly connected to the lower end of the test strip magazine 101. The right end of the sheet metal sliding surface 102 is fixedly connected to the upper end of the fixed support 103. The sheet metal sliding surface 102 is made of mirror-finished stainless steel material, with a smooth surface and no burrs. The color detector 5 is installed at the bottom of the sheet metal sliding surface 102. The shape of the test strip magazine 101 is set as a V shape. The inclined surface of the test strip magazine 101 is set as a V shape to facilitate the downward sliding of the urine test strip 4.
[0032] Please refer to Figure Figure 2 With Figure 3, the scraper screening device 2 includes a driving scraper motor 201, a scraper belt 202 and a scraper runner 203. The driving scraper motor 201 is a 42 or 35 stepping motor, which is used to provide power. The advantages of the stepping motor are stable movement, long service life and high precision. The upper and lower ends of the inner side of the scraper belt 202 are respectively sleeved on the outer walls of the upper and lower scraper runners 203. The back of the lower scraper runner 203 is externally connected to the driving scraper motor 201. The scraper belt 202 is evenly distributed with baffles, and the height value of the baffles is equal to the thickness value of the urine test strip 4. The scraper belt 202 is used to convey the urine test strip 4. Since the test strip bin 101 is a V-shaped inclined surface structure, the urine test strip 4 is always placed obliquely and can be embedded with the scraper.
[0033] The direction adjustment device 3 includes a driving direction motor 301, a rotating belt 302, a pulley 303 and a direction rotating shaft 304. The left and right ends of the inner side of the rotating belt 302 are respectively sleeved on the outer walls of the left and right pulleys 303. The rear end of the left pulley 303 is externally connected to the driving direction motor 301. The driving direction motor 301 is a 42 or 35 stepping motor with an encoder. The advantages of the stepping motor are stable movement, long service life and high precision. The encoder is used to more accurately locate the movement position of the motor to ensure that the opening direction of the direction rotating shaft 304 is exactly tangent to the sheet metal sliding surface 102, so as to ensure that the urine test strip 4 can smoothly slide into the slot of the direction rotating shaft 304. The rear end of the right pulley 303 is fixedly connected to a direction rotating shaft 304 located above the conveying device 6. The direction rotating shaft 304 is made of aluminum alloy and requires anodic oxidation sandblasting treatment, and the inner surface is smooth.
[0034] Please refer to Figure 5 、 Figure 7 and Figure 9 , the inner wall of the side plate 8 is evenly distributed with rotating shafts 15. The outer wall of the rotating shaft 15 is rotationally connected to the inner wall of the roller 23. The rotational connection method reduces the friction between the urine test strip 4 and its contact surface. The outer side of the side plate 8 is fixedly installed with a connecting plate 16 located above the telescopic rod 9. The lower end of the connecting plate 16 is fixedly installed with an annular block 17, and the inner side of the annular block 17 is fixedly connected to the outer end of the telescopic rod 9.
[0035] The outer wall of the telescopic rod 9 is evenly distributed with round rods 18. One end of the round rod 18 away from the telescopic rod 9 is rotationally connected to a ball 19, and the outer wall of the ball 19 is in rolling connection with the inner wall of the sleeve rod 10. The rolling of the ball 19 in the sleeve rod 10 strengthens the stability of the telescopic movement of the telescopic rod 9 in the sleeve rod 10.
[0036] Please refer to Figure Figure 8 and Figure 10, the moving component 11 includes a ball nut 111, a short rod 112, and a ball screw 113. The inner wall of the short rod 112 is threadedly sleeved with the outer wall of the ball screw 113. The threaded sleeved connection method enables the circumferential rotation of the ball screw 113 to provide power for the horizontal movement of the ball nut 111, achieving the telescopic movement of the telescopic rod 9. The outer wall of the short rod 112 is fixedly connected to the inner end of the ball nut 111, and the outer end of the ball nut 111 is fixedly connected to the inner wall of the telescopic rod 9.
[0037] A double-shaft motor 20 is fixedly installed at the inner end of the ball screw 113. The outer wall of the double-shaft motor 20 is fixedly sleeved with a chassis 21. A frame 22 is fixedly installed at the upper end of the chassis 21, and the upper end of the frame 22 is fixedly connected to the lower end of the conveying device 6.
[0038] The urine test strip 4 includes a urine test strip color block 401 and a urine test strip substrate 402. The urine test strip color block 401 is mainly composed of the colors of various pre-planned different dyes, filter paper, and corresponding chemicals, and will undergo corresponding chemical reactions with the components in urine. The bottom surface of the urine test strip color block 401 is connected to the top surface of the urine test strip substrate 402. The urine test strip color block 401 is composed of various pre-planned different colors, filter paper, and corresponding chemicals. The urine test strip substrate 402 is made of white PET material. The urine test strip substrate 402 uses white PET material, which has high hardness, light weight, and is resistant to chemical corrosion in urine.
[0039] In summary, for the new urine test strip screening device, during use, first place the urine test strip 4 in the test strip magazine 101. By starting the scraper screening device 2, the urine test strip 4 is conveyed from the bottom to the top, and then slides down along the sheet metal sliding surface 102 into the direction rotating shaft 304. During the downward sliding of the urine test strip 4, the color detector 5 detects the front and back directions of the urine test strip 4, and transmits the signal of the detection result to the direction adjustment device 3. When the urine test strip 4 is in the correct orientation, the side with the colored block on the urine test strip 4 is facing forward at this time, and the direction adjustment device 3 rotates counterclockwise. The urine test strip 4 slides down from the inside of the direction rotating shaft 304 to the conveying device 6. When the urine test strip 4 is in the reverse orientation, the direction adjustment device 3 rotates clockwise, and the urine test strip 4 slides down from the inside of the direction rotating shaft 304 to the conveying device 6, thus completing the entire screening and correction process. Finally, adjust the distance between the rollers 23 on the front and rear sides according to the size of the urine test strip 4. By turning on the double-shaft motor 20 to drive the rotation of the front and rear ball screws 113, due to the threaded socket connection between the ball screw 113 and the short rod 112, the circumferential rotation of the ball screw 113 drives the horizontal movement of the short rod 112. The movement of the short rod 112 drives the movement of the telescopic rod 9 inside the sleeve rod 10 through the connection of the ball nut 111. The movement of the telescopic rod 9 drives the movement of the front and rear side plates 8 until the side plates 8 are adjusted to the appropriate position. The rotation of the rollers 23 on the rotating shaft 15 reduces the friction between the urine test strip 4 and the rollers 23 when the urine test strip 4 is conveyed on the conveying device 6.
