Description

Technical Field

[0001] The present invention relates to the technical field of sampling tubes for immunoassay tests, and particularly to a novel sampling tube for immunoassay tests. Background Art

[0002] Currently, the global disease spectrum is constantly changing, and new infectious diseases emerge in an endless stream. As an important diagnostic method, immunoassay is widely used in the fields of infectious diseases, tumor marker detection, and autoimmune disease diagnosis, which puts forward higher requirements for the performance and quality of sampling tubes.

[0003] Immunoassay test is a process of qualitatively and quantitatively measuring immune molecules and immune cells, and its clinical significance can be analyzed according to the test results. Immunoassay test includes cell immune detection and humoral immune detection. When performing humoral immune detection, it is necessary to sample the liquid, and at this time, a sampling tube can be used. When using the sampling tube to sample the sample, the existing sampling tube is not easy to filter the sample, and the sample may contain impurities, which affects the test results of the sample. Therefore, an immunoassay test sampling tube is needed for operation.

[0004] After retrieval, a Chinese patent with the publication number CN221868510U proposed a sampling tube for immunoassay tests, including a sampling tube main body, a protective mechanism sleeved on the surface of the sampling tube main body, and a disassembly mechanism inserted into the top surface of the sampling tube main body. For this immunoassay test sampling tube, through the settings of the filtering mechanism and the disassembly mechanism, when filtering the sample, the sample first passes through the nylon membrane, and the nylon membrane filters and removes large particle impurities in the sample. Then it passes through the nitrocellulose membrane at the bottom. The nitrocellulose membrane can effectively filter out cell debris and microorganisms, maintaining the purity of the sample. And by rotating the connection interface, the two limit columns on the surface of the pin at the bottom of the connection interface form a passage with the slide rail interface at the top of the sampling tube main body, and then the connection interface can be removed from the sampling tube main body to clean and replace the filtering mechanism inside the connection interface, extending the service life of the filtering mechanism.

[0005] Although the above sampling tube can achieve sample filtration and can disassemble and clean the filtration structure, other devices are still needed for mixing and centrifugation after sampling. Summary of the Invention

[0006] Aiming at the above problems, the present invention aims to provide a novel sampling tube for immunoassay tests, which can be conveniently used to complete sampling without contact; secondly, it can filter the sample during the inhalation process to prevent impurities from entering the sample; in addition, the device should be easy to disassemble and clean; and it can use the same device to complete suction, filtration, mixing, and centrifugation.

[0007] The main idea of the technical solution adopted by the present invention: By designing a suction tube, a suction seat is detachably arranged at the orifice of the suction tube, which can realize the filtration of the sample; a scale is arranged on the outer wall of the suction tube to facilitate reading the sample volume; a fixed seat is arranged at the open end of the suction tube, a driving tube is arranged on the fixed seat, a piston rod and a rotating rod are movably connected in the driving tube, the piston rod is driven by an electric telescopic rod to slide in the suction tube to generate suction force, and the sample is sucked into the suction tube; a stirring rod is arranged at the end of the rotating rod, the stirring rod can accelerate the mixing of the sample and the experimental reagent, a sliding seat is slidably connected to the stirring rod, by controlling the distance between the magnetic ring and the sliding seat, the connection and separation of the stirring rod and the suction tube can be realized. When the magnetic ring approaches the sliding seat, the sliding seat moves away from the magnetic ring under the repulsive magnetic force, but due to the limitation of the stirring rod, the sliding seat can only move away from the stirring rod. When the sliding seat corresponds to the groove on the suction tube, the repulsive magnetic force received by the sliding seat is greater than the resistance of the spring compression and the suction force of the magnetic sleeve. Since the depth of the groove is less than the length of the sliding seat, part of the sliding seat will enter the groove, and the other part is still on the stirring rod. At this time, the stirring rod and the suction tube are connected through the sliding seat. When the rotating rod rotates, the stirring rod can drive the suction tube to rotate synchronously to realize the centrifugation of the sample.

[0008] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A new type of immunological test sampling tube, comprising a suction tube, a driving tube is arranged on the suction tube, a driving component and a rotating rod are arranged in the driving tube, the driving component is connected with the rotating rod and the free end is located inside the suction tube, and a telescopic stirring component is connected to the free end of the rotating rod. The driving component can control the length of the stirring component to realize the connection or separation of the stirring component and the suction tube.

[0009] Through the above technical solution, further: A motor bracket is arranged on the driving tube, a motor is arranged on the motor bracket, and the output end of the motor is connected with the rotating rod.

[0010] Through the above technical solution, further: The stirring component includes a stirring rod and a sliding seat connected to each other, and the sliding seat is slidably connected to the stirring rod.

[0011] Through the above technical solution, further: A magnetic sleeve is also arranged on the stirring rod, and the magnetic sleeve is magnetically attracted to the sliding seat.

[0012] Through the above technical solution, further: The driving component includes an electric telescopic rod arranged on the motor bracket, a magnetic ring is connected to the free end of the electric telescopic rod, the magnetic poles of the magnetic ring are respectively located in the upper half and the lower half, and the magnetic poles on the side of the magnetic ring close to the sliding seat are the same.

[0013] Through the above technical solution, further: four grooves evenly distributed along the circumference are opened on the inner wall of the suction tube, and springs are arranged in the grooves.

[0014] Through the above technical solution, further: a longitudinal groove is opened on the side wall of the driving tube, a toggle rod is slidably connected in the longitudinal groove, the toggle rod is fixedly connected to a piston rod, and the piston rod is sleeved on the rotating rod.

[0015] Through the above technical solution, further: a suction seat is detachably provided at the pipe mouth of the suction pipe, and a filter screen and a one-way valve are provided on the suction seat.

[0016] Through the above technical solution, further: a non-slip handle is provided on the suction tube.

[0017] A method for using a novel immunoassay sampling tube, using any of the novel immunoassay sampling tubes described above, and the specific operating steps are as follows: S1. Absorb the sample. When the toggle rod is pushed upward, the piston rod can be driven to move upward, thereby realizing negative pressure suction in the aspiration tube. The sample liquid enters the aspiration tube through the aspiration seat, and the aspiration seat is responsible for filtering the sample liquid.

[0018] S2. Stir and mix. Start the motor. The output shaft of the motor drives the rotating rod to rotate, and then drives the stirring rod to rotate. The stirring rod can drive the liquid in the suction tube to rotate, thereby accelerating the mixing of the sample and the experimental reagent.

[0019] S3, rotating centrifuge, the electric telescopic rod extends, so that the magnetic ring approaches the sliding seat, and the sliding seat is moved in the direction away from the magnetic ring by the repulsive magnetic force. However, due to the limitation of the stirring rod, the sliding seat can only move toward the outlet of the stirring rod. When the sliding seat corresponds to the position of the groove, the repulsive magnetic force on the sliding seat is greater than the resistance of the spring compression and the suction force of the magnetic sleeve. Since the groove depth is less than the length of the sliding seat, part of the sliding seat will enter the groove, and the other part will still be on the stirring rod. At this time, the stirring rod and the suction tube are connected through the sliding seat. When the rotating rod rotates, the stirring rod can drive the suction tube to rotate synchronously to realize the centrifugation of the sample, remove bubbles in the liquid, and avoid deviations in the test results. After the centrifugation is completed, the electric telescopic rod is shortened to drive the magnetic ring away from the sliding seat, reducing the repulsive magnetic force on the sliding seat. At this time, the elastic force of the spring recovery and the magnetic suction force of the magnetic sleeve are larger, and the sliding seat returns to the stirring rod, canceling the connection between the stirring rod and the suction tube.

[0020] The beneficial effects of the present invention are: 1. By designing the suction tube, a suction seat is detachably provided at the mouth of the suction tube. A filter screen and a one-way valve are provided in the suction seat to filter out impurities and particles in the sample. The one-way valve prevents the sample liquid from flowing out from the bottom. After use, the suction seat can be removed for cleaning and to remove the sediment on the top of the one-way valve; 2. There is a scale on the outer wall of the pipette tube to facilitate reading of the sample volume; 3. A fixed seat is provided at the open end of the suction tube, and a driving tube is provided on the fixed seat. A piston rod and a rotating rod are movably connected in the driving tube. A longitudinal groove is provided on the side wall of the driving tube, and the toggle rod slides in the longitudinal groove. When the toggle rod is toggled by hand, the piston rod can be driven to move up and down; specifically, when the toggle rod is toggled upward, the piston rod can be driven to move upward, thereby realizing negative pressure suction in the suction tube, which is convenient for sample collection; 4. A motor bracket is provided at one end of the driving tube, a motor is provided on the motor bracket, a rotating rod is provided on the output shaft of the motor, the rotating rod rotates coaxially with the output shaft of the motor, and the free end of the rotating rod extends into the suction tube. When the rotating rod rotates, the liquid in the suction tube can be driven to rotate, thereby accelerating the mixing of the sample and the experimental reagent; 5. A stirring rod is provided at the end of the rotating rod, which can accelerate the mixing of the sample and the experimental reagent. A sliding seat and a magnetic sleeve are provided at the free end of the stirring rod. The sliding seat is slidably connected to the stirring rod, and the magnetic sleeve is fixedly connected to the stirring rod. Under initial conditions, the sliding seat and the magnetic sleeve are attracted to each other by the magnetic influence. When the electric telescopic rod is extended to make the magnetic ring close to the sliding seat, the sliding seat is moved in the direction away from the magnetic ring by the repulsive magnetic force. However, due to the limitation of the stirring rod, the sliding seat can only move in the direction away from the stirring rod. When the sliding seat corresponds to the position of the groove, the repulsive magnetic force on the sliding seat is greater than the resistance of the spring compression and the suction force of the magnetic sleeve. Since the depth of the groove is less than the length of the sliding seat, part of the sliding seat will enter the groove, and the other part will still be on the stirring rod. At this time, the stirring rod is connected to the suction tube through the sliding seat. When the rotating rod rotates, the stirring rod can drive the suction tube to rotate synchronously to realize the centrifugation of the sample, remove bubbles in the liquid, and avoid deviations in the test results.

Specific embodiments

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0023] The inventors' research found that immunoassay is a process for qualitatively and quantitatively determining immune molecules and immune cells, and the clinical significance can be analyzed based on the test results. Immunoassay includes cellular immunity detection and humoral immunity detection. When performing humoral immunity detection, a liquid sample needs to be taken, and a sampling tube can be used at this time. When using the sampling tube to sample the sample, the existing sampling tube is not easy to filter the sample, and the sample may contain impurities, which affects the test results of the sample. Moreover, other devices are still required for mixing and centrifugation after sampling.

[0024] Based on the above findings, the present application proposes a new type of sampling tube for immunoassay. By designing the suction tube 1, a suction seat 2 is detachably arranged at the mouth of the suction tube 1. A filter screen 201 and a one-way valve 202 are arranged in the suction seat 2, which can filter out impurities and particulate matters in the sample, and the one-way valve 202 prevents the sample liquid from flowing out from the bottom; after use, the suction seat 2 can be removed for cleaning and removing the sediment on the upper part of the one-way valve 202. A scale is arranged on the outer wall of the suction tube 1 for facilitating the reading of the sample volume. A fixed seat 4 is arranged at the open end of the suction tube 1, and a drive tube 5 is arranged on the fixed seat 4. A piston rod 10 and a rotating rod 8 are movably connected in the drive tube 5. The piston rod 10 drives it to slide in the suction tube 1 through a toggle rod 13 to generate suction force, and the sample is sucked into the suction tube 1. A stirring rod 9 is arranged at the end of the rotating rod 8, and the stirring rod 9 can accelerate the mixing of the sample and the experimental reagent. A sliding seat 901 and a magnetic sleeve 902 are arranged at the free end of the stirring rod 9. The sliding seat 901 is slidably connected to the stirring rod 9, and the magnetic sleeve 902 is fixedly connected to the stirring rod 9. Under the initial condition, the sliding seat 901 and the magnetic sleeve 902 are attracted to each other by magnetic force. When the electric telescopic rod 11 extends and the magnetic ring 12 approaches the sliding seat 901, the sliding seat 901 moves away from the magnetic ring 12 under the repulsive magnetic force. However, due to the limitation of the stirring rod 9, the sliding seat 901 can only move away from the stirring rod 9. When the sliding seat 901 corresponds to the position of the groove 102, the repulsive magnetic force received by the sliding seat 901 is greater than the resistance of the spring 103 being compressed and the suction force of the magnetic sleeve 902. Since the depth of the groove 102 is less than the length of the sliding seat 901, part of the sliding seat 901 will enter the groove 102, and the other part is still on the stirring rod 9. At this time, the stirring rod 9 is connected to the suction tube 1 through the sliding seat 901. When the rotating rod 8 rotates, the stirring rod 9 can drive the suction tube 1 to rotate synchronously to realize the centrifugation of the sample.

[0025] Embodiment 1 Refer to Figures 1 - 15 , the present application discloses a new type of sampling tube for immunoassay, including a suction tube 1. The structure of the suction tube 1 is similar to that of a syringe. The suction tube 1 is made of a hard material and is provided with an observation window. The window is made of a transparent material, and a scale is arranged on the outer wall at the window for facilitating the reading of the sample volume.

[0026] The suction seat 2 is detachably provided at the mouth of the suction tube 1, and the suction seat 2 and the mouth of the suction tube 1 are plug-in structures. The suction seat 2 is sequentially provided with a filter 201 and a one-way valve 202. The filter 201 can filter out impurities and particulate matter in the sample, and the one-way valve 202 can prevent the sample liquid from flowing out from the bottom, so that the sample can only flow from the outside to the inside. After the sampling tube is used, the suction seat 2 can be removed to remove the sediment on the one-way valve 202, and then it is cleaned and disinfected for the next use.

[0027] A limit ring 101 is arranged on the outer wall of the suction tube 1, and a non-slip handle 3 is detachably arranged on the limit ring 101. The part where the non-slip handle 3 is connected to the limit ring 101 is made of deformable silicone material for easy disassembly, and the hand-held part is made of hard material for easy gripping.

[0028] The open end of the suction tube 1 is clamped with a fixing seat 4, a driving tube 5 is fixedly arranged on the fixing seat 4, a motor bracket 6 is arranged at one end of the driving tube 5 away from the fixing seat 4, a motor 7 is arranged on the motor bracket 6, and the output shaft of the motor 7 is arranged coaxially with the driving tube 5. A rotating rod 8 is arranged on the output shaft of the motor 7, and the rotating rod 8 rotates coaxially with the output shaft of the motor 7. The free end of the rotating rod 8 extends into the suction tube 1. When the rotating rod 8 rotates, it can drive the liquid in the suction tube 1 to rotate, thereby accelerating the mixing of the sample and the experimental reagent.

[0029] Embodiment 2 The rotating rod 8 is also sleeved with a piston rod 10, one end of which is located in the suction tube 1 and is slidably connected to the suction tube 1, and the other end is located inside the driving tube 5 and is connected to a toggle rod 13. A longitudinal groove 501 is provided on the side wall of the driving tube 5, and the toggle rod 13 slides in the longitudinal groove 501. When the toggle rod 13 is manually toggled, the piston rod 10 can be driven to move up and down. Specifically, when the toggle rod 13 is toggled upward, the piston rod 10 can be driven to move upward, so that negative pressure suction is achieved in the suction tube 1, which is convenient for sample collection.

[0030] Embodiment 3 Four stirring rods 9 are evenly arranged at the free end of the rotating rod 8. A sliding groove is provided at the free end of the stirring rod 9. A sliding seat 901 is slidably arranged on the sliding groove. The magnetic poles of the sliding seat 901 are respectively located in the upper half and the lower half. The rotating rod 8 is made of a non-magnetic material, such as plastic. A magnetic sleeve 902 is slidably arranged inside the sliding seat 901. The magnetic poles of the magnetic sleeve 902 are respectively located in the upper half and the lower half. The magnetic poles of the sliding seat 901 and the magnetic sleeve 902 are opposite, so the two attract each other in the absence of external force.

[0031] There are also two electric telescopic rods 11 provided on the motor bracket 6. A magnetic ring 12 is fixedly connected to the free end of the electric telescopic rod 11. The magnetic poles of the magnetic ring 12 are respectively located in the upper half and the lower half, and the magnetic poles of the magnetic ring 12 close to the sliding seat 901 are the same. Therefore, when the magnetic ring 12 approaches the sliding seat 901, the sliding seat 901 is subjected to a repulsive magnetic force and moves in a direction away from the magnetic ring 12. The magnetic ring 12 is made of a strong magnetic material.

[0032] Four grooves 102 are provided on the inner wall of the suction tube 1. The positions of the grooves 102 correspond to the positions of the stirring rod 9. Springs 103 are fixedly arranged in the grooves 102. In the initial state, the length of the spring 103 is the same as the depth of the groove 102. At this time, the spring 103 is in a stretched state.

[0033] When the electric telescopic rod 11 extends and the magnetic ring 12 approaches the sliding seat 901, the sliding seat 901 is subjected to a repulsive magnetic force and moves in a direction away from the magnetic ring 12. However, due to the limitation of the stirring rod 9, the sliding seat 901 can only move in a direction away from the stirring rod 9. When the sliding seat 901 corresponds to the position of the groove 102, the repulsive magnetic force received by the sliding seat 901 is greater than the resistance of the spring 103 being compressed and the suction force of the magnetic sleeve 902. Since the depth of the groove 102 is less than the length of the sliding seat 901, part of the sliding seat 901 will enter the groove 102, and the other part is still on the stirring rod 9. At this time, the stirring rod 9 and the suction tube 1 are connected through the sliding seat 901. When the rotating rod 8 rotates, the stirring rod 9 can drive the suction tube 1 to rotate synchronously, realizing the centrifugation of the sample, removing the bubbles in the liquid, and avoiding deviation of the detection result. After the centrifugation is completed, the electric telescopic rod 11 shortens to drive the magnetic ring 12 away from the sliding seat 901, reducing the repulsive magnetic force received by the sliding seat 901. At this time, the restoring elastic force of the spring 103 and the magnetic suction force of the magnetic sleeve 902 are relatively large, and the sliding seat 901 returns to its original position, canceling the connection between the stirring rod 9 and the suction tube 1.

[0034] The usage process of the present invention is as follows: 1. Absorb the sample. When the toggle rod 13 is toggled upward, it can drive the piston rod 10 to move upward, so that negative pressure suction is realized inside the suction tube 1, and the sample liquid enters the suction tube 1 through the suction seat 2. The suction seat 2 is responsible for filtering the sample liquid.

[0035] 2. Stir and mix. Start the motor 7. The output shaft of the motor 7 drives the rotating rod 8 to rotate, and then drives the stirring rod 9 to rotate. The stirring rod 9 can drive the liquid in the suction tube 1 to rotate, accelerating the mixing of the sample and the experimental reagent.

[0036] 3. Rotational centrifugation. When the electric telescopic rod 11 extends and the magnetic ring 12 approaches the sliding seat 901, the sliding seat 901 moves away from the magnetic ring 12 under the repulsive magnetic force. However, due to the restriction of the stirring rod 9, the sliding seat 901 can only move away from the stirring rod 9. When the sliding seat 901 corresponds to the position of the groove 102, the repulsive magnetic force on the sliding seat 901 is greater than the resistance of the compressed spring 103 and the suction force of the magnetic sleeve 902. Since the depth of the groove 102 is less than the length of the sliding seat 901, part of the sliding seat 901 will enter the groove 102, and the other part remains on the stirring rod 9. At this time, the stirring rod 9 is connected to the suction tube 1 through the sliding seat 901. When the rotating rod 8 rotates, the stirring rod 9 can drive the suction tube 1 to rotate synchronously to achieve centrifugation of the sample, remove the bubbles in the liquid, and avoid deviation of the detection results. After centrifugation, the electric telescopic rod 11 shortens to drive the magnetic ring 12 away from the sliding seat 901, reducing the repulsive magnetic force on the sliding seat 901. At this time, the restoring elastic force of the spring 103 and the magnetic suction force of the magnetic sleeve 902 are relatively large, and the sliding seat 901 returns to its original position, canceling the connection between the stirring rod 9 and the suction tube 1.

[0037] 4. Disassembly and cleaning. The suction seat 2 can be pulled out and disassembled. When the fixed seat 4 is pulled out, the connected drive tube 5 is removed together, and then the suction tube 1 can be cleaned and disinfected.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
