Abstract

This invention discloses an integrated drug urine test card with multiple detection functions, relating to the field of prohibited substance detection technology. It includes a main urine test card body, with a sampling area and a test display area evenly distributed on its upper surface. The main urine test card body is equipped with a dropper. Above the main urine test card body is a limiting drip mechanism for precise drip control. Clamping plates are symmetrically arranged on both sides of the upper end of the dropper, and slotted horizontal plates are slidably connected below each clamping plate. Through the coordinated use of torsion spring pawls, limiting shafts, baffles, etc., and utilizing timely limiting via mechanical transmission, the number of drops of urine sample to be tested from the dropper is precisely controlled.

Description

Technical Field

[0001] This invention relates to the field of contraband detection technology, specifically to an integrated drug urine test card with multiple detection functions. Background Technology

[0002] Currently, most existing methods for detecting drug users employ colloidal gold immunochromatography. This method uses a urine test card and utilizes the principle of immune competitive inhibition. Drug antigens are coated onto a nitrocellulose membrane, and specific antibodies labeled with colloidal gold are coated onto glass fibers. By dropping the urine sample onto the drug antigen packet, a reaction can be initiated to quickly determine whether a person has used drugs. Meanwhile, a multi-drug combined test kit card was disclosed in the authorization announcement number "CN218896118U", including a box body, a cover, several test strips and a support. The cover is located at the lower end of the box body, the several test strips are located inside the box body, one end of the test strip is located in the inner cavity of the cover body, and the support is installed on the box body. The support is used to stabilize the box body and the cover body. When the multi-drug combined test kit card is used for testing, the support of the support makes the multi-drug combined test kit card more stable when standing, thereby ensuring the accuracy of the test results. As can be seen from the above-mentioned device, although it ensures the accuracy of the test results, it still has the following shortcomings when combined with existing technology and specific usage conditions: ①When the above-mentioned test card and the urine test card in the prior art are used, the sampling area and the detection area on the surface are directly exposed to the external environment. If the environment in which the urine test card is used is poor, or if the test personnel are negligent, the sampling area and the detection area in the urine test card will be contaminated by dust particles in the air, which will cause the overall detection function of the urine test card to fail, and thus the detection work cannot be carried out smoothly. ② In addition, most existing urine test cards use manual hand-held dripping of urine to be tested. Although this method is simple and quick, it is impossible to accurately control the number of drops of urine into the sampling area when manually dripping urine. According to the current instructions for use of urine test cards, it is generally required to drip three drops. Dripping too much or too little urine will cause the water pressure entering the urine test plate to be too high or too low, thus affecting the accuracy of the final urine test data. Therefore, in view of this, the present invention proposes an integrated drug urine test card with multiple detection functions to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides an integrated drug urine test card with multiple detection functions, thereby resolving the corresponding technical issues raised in the background section.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an integrated drug urine test card with multiple detection functions, including a main urine test card body, wherein a sampling area and a test display area are evenly arranged on the upper surface of the main urine test card body, and the main urine test card body is equipped with a rubber dropper, which is vacuum packaged and produced together with the main urine test card body. The rubber dropper is used to draw urine samples and add urine samples to the sampling area. The upper part of the main urine test card body includes: an external barrier mechanism to ensure the effectiveness of the test, a limited dripping mechanism to achieve precise dripping control, and a dropper positioning mechanism to ensure the stability of the dripping. The external barrier mechanism includes: a partition, a baffle, a convex ring, and a sealing ring. A partition integrally formed with the main urine test card is arranged parallel to the top of the main urine test card. A baffle is evenly arranged on one side of the upper part of the partition. The baffle is made of transparent material and has a conical cavity structure that is narrow at the top and wide at the bottom. A connecting hole is opened through the surface of the partition below the baffle. A convex ring is fixedly connected to the lower end face of the baffle. The position of the convex ring corresponds to the position of the sampling area. The lower end face of the convex ring is tightly attached to the upper end face of the main urine test card through the sealing ring.

[0005] Furthermore, the shape of the partition is adapted to the upper shape of the urine test main card, the partition is made of transparent material, and there is a gap between the partition and the upper surface of the urine test main card.

[0006] Furthermore, the outer diameter of the convex ring portion is adapted to the inner diameter of the connecting hole, and the connecting hole and the convex ring portion are threadedly connected.

[0007] Furthermore, multiple sealing rings are evenly distributed, and each sealing ring is fixedly installed on the lower end face of the convex ring portion.

[0008] Further, the limited-number dispensing mechanism includes: clamping plates, slotted horizontal plates, reset springs, follower bars, torsion spring pawls, ratchet wheels, limiting shafts, baffles, and fixing plates. Clamping plates are symmetrically arranged on both sides of the upper end of the dropper. Slotted horizontal plates are slidably connected to the lower part of each clamping plate. A follower bar is fixedly connected to the outer wall of the clamping plate on the side away from the dropper. A torsion spring pawl is rotatably connected to the end of the follower bar on the side away from the clamping plate. A ratchet wheel is arranged parallel to the side of the torsion spring pawl away from the follower bar. The ratchet wheel is rotatably connected to the opening... On the upper end face of the slotted plate, the ratchet and the torsion spring pawl mesh with each other. That is, when the torsion spring pawl moves horizontally with the follower bar, it can complete the meshing transmission with the limiting shaft. The limiting shaft is fixedly connected to the eccentric part of the upper end face of the ratchet. A fixing plate is fixedly connected to the outer wall of the clamping plate near the limiting shaft. A baffle is hinged to the side of the fixing plate away from the clamping plate. Note: The hinge method of the fixing plate and the baffle is limited: the baffle can only be rotated upwards. The baffle is located on the movement path of the limiting shaft, and the limiting shaft can abut against the baffle after movement.

[0009] Furthermore, the clamps are arranged in parallel, and the outer dimensions of the clamps are larger than the outer diameter of the upper part of the dropper.

[0010] Furthermore, the portion of the slotted horizontal plate near the axis of the dropper is a ring structure, and the diameter of the ring structure is equal to the outer diameter of the lower end of the dropper.

[0011] Furthermore, the dropper positioning mechanism includes: a fixed rod, a T-shaped positioning component, a connecting shaft, a slide plate, a bracket, a positioning ring, a guide groove, and a sliding shaft. A fixed rod is symmetrically fixedly connected to the outer wall of the slotted horizontal plate away from the clamping plate. A slide plate is fixedly connected to the lower end of the fixed rod. A T-shaped positioning component is slidably connected inside the slide plate. The T-shaped positioning component includes an arc-shaped plate near the end of the dropper and a cuboid plate slidably connected inside the slide plate. The arc-shaped plate near the end of the dropper in the T-shaped positioning component... A connecting shaft is fixedly connected to the outer wall of the plate. The upper end of the connecting shaft passes through the interior of the slotted horizontal plate and is fixedly connected to the bottom of the clamping plate. The end of the slide plate away from the dropper is fixedly connected to the outer wall of the cover by a bracket. A positioning ring is rotatably connected to the upper end face of the bracket. A guide groove is evenly opened through the surface of the positioning ring. The guide groove is distributed in a concentric arc shape. A sliding shaft is slidably connected inside the guide groove. The lower end of the sliding shaft is rotatably connected to the upper end face of the cuboid plate in the T-shaped positioning component.

[0012] Furthermore, the T-shaped positioning element and the slide plate are grouped together, and there are four groups of T-shaped positioning elements and slide plates, which are distributed in a circle around the periphery of the dropper.

[0013] Compared with the prior art, the beneficial effects of the present invention are: (1) By using the combination of torsion spring pawl, limiting shaft, baffle, etc., the timely limiting of mechanical transmission can be used to achieve precise control of the number of drops of urine sample to be tested from the dropper, thereby avoiding the situation where too many or too few drops of urine sample to be tested are added into the sampling area due to the negligence of the test personnel or improper operation, which would lead to the water pressure in the sampling area being too high or too low, thus avoiding affecting the accuracy and scientific nature of the final urine test data. (2) By integrating a transparent partition on the top of the urine test main card, the partition can cover the top of the urine test main card, which can not only prevent small impurities in the external environment from falling into the sampling area and test display area to avoid affecting the normal detection effect of the urine test main card, but also the transparent partition will not affect the normal observation of the test display area by the test personnel. (3) By utilizing the circular structure in the slotted horizontal plate and the baffle with a conical cavity structure that is narrow at the top and wide at the bottom, the downward movement path of the dropper can be limited and guided, ensuring that the dropper remains on the same axis as the sampling area during the downward movement. This not only ensures that the dropper accurately drips the urine sample into the sampling area, but also avoids the situation where the dropper is tilted when held manually, which would prevent the urine testing process from proceeding smoothly. (4) When the T-shaped positioning component moves along the trajectory of the guide groove, the stability of the dropper will be fully guaranteed by the action of the arc plate in each T-shaped positioning component when the dropper drips the urine sample to be tested. This will further ensure the verticality of the dropper when it drips the urine sample to be tested, which is conducive to the urine falling accurately into the sampling area.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Embodiments of the present invention Please refer to Figure 2 As shown, an integrated drug urine test card with multiple detection functions includes a urine test main card body 1. The upper surface of the urine test main card body 1 is evenly provided with a sampling area 11 and a test display area 12. The urine test main card body 1 is equipped with a rubber dropper 13. The rubber dropper 13 is vacuum packaged together with the urine test main card body 1. The rubber dropper 13 is used to draw urine samples and add urine samples to the sampling area 11. When using this urine test master card 1, the urine sample to be tested can be drawn using the dropper 13 that comes with the urine test master card 1, and dripped into the sampling area 11. If the drawn urine sample does not contain the target drug or its metabolites, the colloidal gold-labeled specific antibody in the test display area 12 will bind to the membrane antigen, forming two red lines: a reaction line T and a control line C. This result indicates that the test result is negative. The upper surface of this urine test master card 1 is provided with two sampling areas 11, and the urine sample to be tested can be dripped into the two sampling areas 11 respectively, thereby achieving the effect of multiple detection functions. If the urine sample drawn by the dropper 13 contains the target drug or its metabolites, and the concentration is higher than the detection level (i.e., different for each test item), then the drug molecules will compete with the colloidal gold-labeled antibody in the test display area 12 for binding, thereby preventing the colloidal gold-labeled antibody from binding to the membrane antigen, causing the corresponding red reaction line to disappear, and only a red control line to appear, thus indicating a positive test result.

[0018] Please refer to Figures 1 to 6 As shown, the external barrier mechanism can be used to ensure effective detection: A partition 21, integrally formed with the main body 1, is disposed parallel to the top of the main body 1. The shape of the partition 21 matches the upper shape of the main body 1. The partition 21 is made of transparent material. A gap is left between the partition 21 and the upper surface of the main body 1. A shield 22 is evenly disposed on one side above the partition 21. The shield 22 is made of transparent material and has a conical cavity structure that is narrower at the top and wider at the bottom. The bottom of the shield 22 penetrates the surface of the partition 21. A connecting hole 23 is provided, and a protruding ring 24 is fixedly connected to the lower end face of the cover 22. The outer diameter of the protruding ring 24 is adapted to the inner diameter of the connecting hole 23, and the connecting hole 23 and the protruding ring 24 are threadedly connected. The position of the protruding ring 24 corresponds to the position of the sampling area 11. The lower end face of the protruding ring 24 is tightly attached to the upper end face of the urine test main card body 1 through a sealing ring 25. Multiple sealing rings 25 are evenly arranged, and all sealing rings 25 are fixedly installed on the lower end face of the protruding ring 24. In summary, in comparison with the prior art where the sampling area 11 and test display area 12 of the urine test card are completely exposed to the external environment, the urine test main card body 1 designed in this solution can effectively protect the sampling area 11 and test display area 12 after removal through the partition 21 and the shield 22, thereby ensuring the effectiveness of the sampling area 11 and test display area 12 in the urine test main card body 1 during use.

[0019] Please refer to Figure 1 , Figure 3 , Figure 7 , Figure 9 As shown, a limited-drip sample mechanism can be used to achieve precise drip control: A clamping plate 31 is symmetrically arranged on both sides of the upper end of the dropper 13, and the clamping plates 31 are parallel to each other. The outer dimensions of the clamping plates 31 are larger than the outer diameter of the upper part of the dropper 13. A slotted horizontal plate 32 is slidably connected to the lower part of each clamping plate 31. A follower strip 33 is fixedly connected to the outer wall of the side of the clamping plate 31 away from the dropper 13. A torsion spring pawl 34 is rotatably connected to the end of the follower strip 33 away from the clamping plate 31. A ratchet 35 is arranged parallel to the side of the torsion spring pawl 34 away from the follower strip 33. The ratchet 35 is rotatably connected to the upper end face of the slotted horizontal plate 32. The ratchet pawl 34 engages with the torsion spring pawl 34, meaning that when the torsion spring pawl 34 moves horizontally with the follower 33, it can engage with the limiting shaft 36 to complete the transmission. The limiting shaft 36 is fixedly connected to the upper end face of the ratchet 35 at the eccentric position. A fixing plate 38 is fixedly connected to the outer wall of the clamping plate 31 near the limiting shaft 36. A baffle 37 is hinged to the side of the fixing plate 38 away from the clamping plate 31. Note: The hinge method between the fixing plate 38 and the baffle 37 is limited: the baffle 37 can only be rotated upwards. The baffle 37 is located on the movement path of the limiting shaft 36, and the limiting shaft 36 can abut against the baffle 37 after it moves. In summary, in comparison 2: Compared to existing technologies where most rely on manual hand-held droppers 13 to drip urine samples into the sampling area 11, which cannot effectively control the amount of urine being dripped, this solution employs mechanical transmission with timely limiting and self-locking mechanisms to precisely control the number of drops of urine being dripped, preventing excessively high or low water pressure inside the sampling area 11, thereby ensuring the accuracy and scientific validity of the urine test data.

[0020] Please refer to Figure 8 and Figure 10 As shown, a dropper positioning mechanism can be used to ensure sample drop stability: The slotted horizontal plate 32 has a ring structure near the axis of the dropper 13, and the diameter of the ring structure is equal to the outer diameter of the lower part of the dropper 13. A fixing rod 41 is symmetrically fixed to the outer wall of the end of the slotted horizontal plate 32 away from the clamping plate 31. A slide plate 43 is fixedly connected to the lower end of the fixing rod 41. A T-shaped positioning member 42 is slidably connected inside the slide plate 43. The T-shaped positioning member 42 and the slide plate 43 form a group, and there are four groups of T-shaped positioning members 42 and slide plates 43. These four groups of T-shaped positioning members 42 and slide plates 43 are distributed in a circle around the periphery of the dropper 13. The T-shaped positioning member 42 includes an arc plate near the end of the dropper 13 and a cuboid plate slidably connected inside the slide plate 43. In the T-shaped positioning component 42, a connecting shaft 4201 is fixedly connected to the outer wall of the arc plate near the end of the dropper 13. The upper end of the connecting shaft 4201 passes through the interior of the slotted horizontal plate 32 and is fixedly connected to the bottom of the clamping plate 31. The end of the slide plate 43 away from the dropper 13 is fixedly connected to the outer wall of the cover 22 through the bracket 44. The upper end face of the bracket 44 is rotatably connected to the positioning ring 45. The surface of the positioning ring 45 is evenly provided with guide grooves 46. The guide grooves 46 are distributed in an arc shape and centripetal. The interior of the guide groove 46 is slidably connected to the sliding shaft 47. The lower end of the sliding shaft 47 is rotatably connected to the upper end face of the cuboid plate in the T-shaped positioning component 42. The inner wall of the guide groove 46 is a smooth surface, that is, the friction is small. In summary, comparison 3: Compared with the existing technology where the dropper 13 is manually held and dripped into the sampling area 11 to collect the urine sample, which cannot ensure that the dropper 13 is accurately dripped into the sampling area 11, this solution utilizes the combined use of the slotted horizontal plate 32 and various T-shaped positioning parts 42 to achieve stability and accuracy in the dripping position of the dropper 13 when dripping the urine sample.

[0021] The complete usage steps and working principle of the above embodiments are as follows: Initial state: When not in use, the main card body 1, the cover 22, and all components on the cover 22 are packaged in a vacuum bag. The cover 22 is not fully engaged with the connection hole 23, and the dropper 13 is not inserted into the cover 22. Usage status: First, the testing personnel can remove the urine test main card 1 and the cover 22, and align the convex ring 24 on the lower end face of the cover 22 with the inside of the connecting hole 23. Then, by rotating the cover 22, the convex ring 24 is threaded into the connecting hole 23. After the cover 22 is tightened, the sealing ring 25 on the lower end face of the convex ring 24 is tightly fitted to the outer surface of the sampling area 11, thus completing the installation of the cover 22. Since the cover 22 and the partition 21 can be freely disassembled and installed, it facilitates this urine test. The main card body 1 and the cover 22 are better packaged, and a transparent partition 21 is integrally set on the top of the urine test main card body 1. The partition 21 covers the top of the urine test main card body 1, which can not only prevent small impurities in the external environment from falling into the sampling area 11 and the test display area 12, so as to avoid affecting the normal detection effect of the urine test main card body 1, but also the transparent partition 21 will not affect the test personnel to observe the results displayed in the test display area 12. When testing personnel need to collect samples, they can take out the dropper 13, hold the upper part of the dropper 13 by hand, apply pressure to the upper part of the dropper 13 to cause it to contract, and maintain the contracted state of the upper part of the dropper 13. Then, insert the lower part of the dropper 13 into the urine sample to be tested, and then release the external force on the upper part of the dropper 13. At this time, the upper part of the dropper 13 will automatically return to its original position under the action of the rebound force. This process will accelerate the gel... The airflow velocity inside the dropper 13 causes the air pressure inside the dropper 13 to decrease. At this time, the air pressure inside the dropper 13 is much lower than the normal atmospheric pressure of the external environment. That is, there is a pressure difference between the dropper 13 and the atmospheric pressure. Therefore, under the action of the normal atmospheric pressure, the urine sample to be tested will be drawn into the dropper 13. At the same time, under the action of the external atmospheric pressure, the urine sample to be tested drawn into the dropper 13 will not drip out naturally without being subjected to external force. Subsequently, the testing personnel placed the urine test master card 1 on a horizontal table, and then held the dropper 13, aligning its lower end with the annular structure near the axis of the slotted horizontal plate 32. Since the diameter of this annular structure is equal to the outer diameter of the lower part of the dropper 13, it allows for natural insertion. When the dropper 13 is inserted downwards, its upper end contacts the annular structure, preventing further downward movement. Simultaneously, the lower end of the dropper 13 is positioned directly above the center of the sampling area 11. (See reference [link to reference] for details.) Figure 5As shown, during the downward movement of the aforementioned dropper 13, the circular structure in the slotted horizontal plate 32 and the baffle 22, which is a conical cavity structure that is narrow at the top and wide at the bottom, can limit and guide the downward movement path of the dropper 13, ensuring that the dropper 13 remains on the same axis as the sampling area 11 during the downward movement. This not only ensures that the dropper 13 can accurately drip the urine sample into the sampling area 11, but also avoids the situation where the urine sample cannot be tested smoothly due to tilting when the dropper 13 is held manually. Furthermore, the sealing ring 25 on the bottom surface of the convex ring 24 is tightly attached to the upper surface of the outer periphery of the sampling area 11, preventing the urine sample from splashing out of the sampling area 11 when it drips downward into the sampling area 11. Afterwards, the testing personnel can touch the outer surface of the clamp 31 with their fingers and apply external force to the clamp 31 to approach the upper part of the dropper 13. As the clamp 31 gradually approaches the upper part of the dropper 13, it will apply pressure to the upper part of the dropper 13, and at the same time, it will compress the return spring 3101. At this time, the urine sample to be tested, which was originally drawn into the dropper 13, will drip downward into the sampling area 11. Since the power for the dropper 13 to drip the urine sample to be tested comes from the clamp 31, when the clamp 31 moves towards the upper part of the dropper 13 for the first time, it will slide horizontally along the trajectory of the slotted horizontal plate 32. At the same time, the displacement of the clamp 31 will also drive the follower 33 and the torsion spring pawl 34 to move horizontally. When the torsion spring pawl 34 moves horizontally, based on the ratchet pawl transmission principle, it will drive the ratchet 35 and the limiting shaft 36 at the eccentric position on the upper surface of the ratchet 35. The ratchet pawl 34 and ratchet 35 rotate synchronously, and each engagement of the ratchet pawl 34 and ratchet 35 only rotates the ratchet 35 by 60 degrees. When the clamping plate 31 squeezes the upper part of the dropper 13, a drop of urine sample to be tested will be squeezed out through the lower end of the dropper 13. During this process, the testing personnel can directly observe through the transparent shield 22. After a drop of urine sample to be tested drips from the lower end of the dropper 13, the testing personnel can release the pressure on the clamping plate 31, and then... Under the combined action of the rebound force of the upper part of the dropper 13 and the rebound force of the reset spring 3101, the clamp 31 will be moved away from the upper part of the dropper 13. At this time, the clamp 31 is reset. During the reset process, based on the principle of ratchet and pawl transmission, the torsion spring pawl 34 will abut against the outer wall of the ratchet 35 and drive the torsion spring pawl 34 to twist. Thus, the ratchet 35 and the limiting shaft 36 will not rotate at this time. Simultaneously, after the clamp 31 resets, the lower end of the dropper 13 no longer drips urine sample to be tested. Thus, a single squeeze of the upper part of the dropper 13 by the clamp 31 drips one drop of urine sample to be tested into the sampling area 11. The testing personnel, following the same principle of squeezing the clamp 31, perform this operation twice more. After these three operations, the ratchet 35 and the limiting shaft 36 will rotate a total of 180 degrees. Since the baffle 37 is located on the movement path of the limiting shaft 36, and the limiting shaft 36 can engage with the baffle 37 after its movement, the limiting shaft 36 will contact the surface of the baffle 37 after rotating 180 degrees. The specific principle of this part is as follows: Figure 7 As shown, if the testing personnel apply pressure to the clamp 31 at this time, and try to continue squeezing the upper part of the dropper 13, the ratchet 35 and the limiting shaft 36 will be blocked by the baffle 37 and will not be able to continue rotating. Consequently, the torsion spring pawl 34 will also be unable to move horizontally, and the clamp 31 will also be unable to move horizontally. In this way, through the coordinated use of the torsion spring pawl 34, the limiting shaft 36, the baffle 37, etc., the timely limiting of the mechanical transmission can be used to achieve precise control of the number of drops of urine sample to be tested from the dropper 13. This avoids the situation where too many or too few drops of urine sample to be tested are added into the sampling area 11 due to negligence or improper operation by the testing personnel, which would cause the water pressure inside the sampling area 11 to be too high or too low, thus avoiding affecting the accuracy and scientific nature of the final urine test data. In addition, there is another situation where, if the clamp 31 squeezes the upper part of the dropper 13 three times and fails to drip three drops of urine in time, the tester can observe and flip the baffle 37 upward so that the baffle 37 no longer obstructs the movement of the clamp 31, and then drip the urine to be tested, thereby achieving the flexibility of the device in use.

[0022] Simultaneously, when the clamping plate 31 moves horizontally towards the upper part of the dropper 13, it also drives the connecting shaft 4201 and the T-shaped positioning member 42 to move horizontally. When the T-shaped positioning member 42 moves horizontally, as... Figure 9 As shown, at this time, the T-shaped positioning member 42 will drive the sliding shaft 47 to slide along the trajectory of the guide groove 46, and at the same time, the positioning ring 45 will rotate. After the T-shaped positioning member 42 moves along the trajectory of the guide groove 46, the arc plate part in the fixing rod 41 will gradually approach the outer wall of the dropper 13. And when the clamping plate 31 squeezes the upper part of the dropper 13 each time, the arc plate in the T-shaped positioning member 42 will fit against the outer wall of the dropper 13. Thus, when the dropper 13 drips the urine sample to be tested, the arc plate in each T-shaped positioning member 42 will fully ensure the stability of the dropper 13, thereby further ensuring the verticality of the dropper 13 when dripping the urine sample to be tested, which is conducive to the accurate landing of the urine inside the sampling area 11.

[0023] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
