Description

Technical Field

[0001] The present invention relates to the technical field of antibody storage, in particular to an anti-pollution kit for detecting IgM antibodies and a sealing method thereof. Background Art

[0002] IgM antibodies have powerful bactericidal, complement activation, immune regulation, and agglutination properties, and are also involved in the pathological processes of certain autoimmune diseases and hypersensitivity reactions. The most commonly used methods for measuring IgM antibody levels in serum are single-way immunodiffusion and immunoturbidimetry, but the latter has gradually replaced the former.

[0003] After obtaining the serum sample, the sample needs to be stored, and serum samples are generally obtained in large quantities. When storing, the serum sample needs to be placed in a test tube first, and the test tube is placed in a test kit for storage. In order to improve the stability of the test tube in the test kit, a test tube rack needs to be set in the test kit. In order to facilitate the insertion of the test tube, the placement hole on the test tube rack is generally larger than the diameter of the test tube. Although this facilitates the insertion of the test tube, it also causes the test tube to shake easily in the test tube rack, and there is a risk of the test tube breaking and causing IgM antibody contamination.

[0034] The lifting assembly is provided to avoid interference between the test tube and the cover, and to make the No. 1 support plate, the No. 2 support plate and the cover more stable when the cover is fully opened, so that the position of the test tube is more stable when taking the test tube. On the other hand, when the cover is fully opened, the test tube will protrude from the reagent box body, making it easier for the tester to take it, and avoiding the test tube being completely placed inside the reagent box body, which makes it inconvenient for the tester to take it, resulting in unstable taking and then the test tube breaking.

[0035] By providing a pulling assembly, when the No. 1 support plate and the No. 2 support plate are in the reagent box body, the No. 1 support plate is at the upper end of the test tube, so that the two ends of the test tube are limited, making the test tube more stable. At the same time, when the No. 1 support plate and the No. 2 support plate move upward, the test tube will move toward the No. 1 support plate under the drive of the No. 2 support plate, so that the No. 1 support plate is in the middle position of the test tube, so that when the tester takes the test tube, there is a larger position for taking it, and it is avoided that the test tube is not easy to take or even broken due to the test tube being too small. The convenience of taking is further improved and the antibody contamination due to the broken test tube is avoided.

[0036] By setting up the clamping assembly, when the No. 1 support plate and the No. 2 support plate move to the end of the stroke, the abutment piece can drive the arc-shaped rubber piece to abut against the test tube, thereby improving the strength of the fixation inside the test tube, and avoiding the test tube from shaking due to unstable clamping when the test tube is stored in the reagent box body, and eventually leading to breakage and antibody contamination.

[0047] See also Figures 1 to 7 In an embodiment of the present invention, an anti-contamination kit for detecting IgM antibodies includes: a kit body 1, a loading component, a lifting component, a pulling component and a clamping component.

[0048] A cover plate 2 is rotatably mounted on the reagent kit body 1;

[0049] The loading assembly is arranged in the reagent box body 1, and the loading assembly includes a No. 1 support plate 3 and a No. 2 support plate 4. The No. 1 support plate 3 is provided with a plurality of through holes 5, and the No. 2 support plate 4 is provided with a plurality of supporting bases 6 matching the through holes 5. The No. 2 support plate 4 is provided with a plurality of No. 1 guide rods 7 diagonally, and the interlocking sliding portion 8 provided on the No. 1 support plate 3 can slide on the No. 1 guide rod 7;

[0050] The lifting assembly is connected to the rotating shaft of the first support plate 3 and the cover plate 2. When the cover plate 2 is opened, the lifting assembly can drive the first support plate 3 and the second support plate 4 to move toward the upper part of the reagent box body 1;

[0051] The lifting assembly includes an incomplete gear 21 coaxially fixedly connected to the rotating shaft of the cover plate 2, and the incomplete gear 21 is adapted to a complete gear 22 rotatably mounted on the reagent box body 1. The rotating shaft of the complete gear 22 passes through the reagent box body 1 and is connected to a bevel gear set 23 provided in the reagent box body 1;

[0052] The lifting assembly also includes a driven structure provided between the No. 1 support plate 3 and the reagent box body 1, the driven structure is connected to the bevel gear set 23 via a belt 24, the bevel gear set 23 includes a No. 1 bevel gear and a No. 2 bevel gear rotatably mounted on the reagent box body 1 and meshing with each other, the No. 1 bevel gear is coaxially fixedly connected to the full gear 22, the No. 2 bevel gear is connected to the driven structure via a belt 24, the driven structure includes a turntable 25 rotatably mounted in the reagent box body 1, and a No. 3 pulley 26 is rotatably mounted at an eccentric position of the turntable 25;

[0053] The driven structure further includes a connecting member 29 fixedly connected to the first support plate 3, and a lifting trough 30 is formed on the connecting member 29. The third pulley 26 can roll in the lifting trough 30, wherein the lifting trough 30 includes a second horizontal groove 3001 and a groove 3002 provided on the connecting member 29, and the groove 3002 is connected to one end of the second horizontal groove 3001;

[0054] Furthermore, a vertical plate 27 is fixed to one side of the No. 1 support plate 3 , and the vertical plate 27 is slidably connected to a No. 2 guide rod 28 provided on the reagent box body 1 .

[0055] When in use, the cover 2 is opened to make its rotating shaft drive the incomplete gear 21 to rotate, wherein the upper part of the incomplete gear 21 has teeth and the lower part has no teeth. During the first 90° process of opening the cover 2, the toothed part of the incomplete gear 21 is separated from the complete gear 22, and the complete gear 22 rotates. At this time, the No. 1 support plate 3 and the No. 2 support plate 4 are inside the reagent box body 1 to avoid interference between the test tube and the cover 2. When the cover 2 is opened from 90° to 180°, the toothed part of the incomplete gear 21 will mesh with the complete gear 22 and drive the complete gear 22 to rotate. At this time, the complete gear 22 will drive the turntable 25 to rotate through the bevel gear set 23 and the belt 24. In the initial state, the axis connecting the No. 3 pulley 26 and the turntable 25 is horizontal. When the turntable 25 rotates, the No. 3 pulley 26 will make a circular motion and move along the No. 2 pulley. The horizontal slot 3001 moves in the length direction until the turntable 25 follows the full gear 22 to rotate 90 degrees, so that the axis line connecting the No. 3 pulley 26 and the turntable 25 is in a vertical state. At this time, the No. 3 pulley 26 moves to the end of the No. 2 horizontal slot 3001. Under the stopper at the end of the No. 2 horizontal slot 3001, the turntable 25 stops rotating, thereby fixing the position of the cover plate 2, improving the position stability of the cover plate 2, and when the No. 3 pulley 26 moves to the end of the No. 2 horizontal slot 3001, the No. 3 pulley 26 will enter the groove 3002, and the center line connecting the No. 3 pulley 26 and the turntable 25 remains in a vertical state, avoiding the turntable 25 from rotating in the opposite direction due to the total weight of the No. 1 support plate 3, the No. 2 support plate 4 and the test tube inserted therebetween, thereby further improving the stability of the No. 1 support plate 3, the No. 2 support plate 4 and the cover plate 2 when the cover plate 2 is fully opened;

[0056] Secondly, when the turntable 25 rotates 90°, the connecting piece 29 will move upward, driving the No. 1 support plate 3 to move upward, so that the test tubes on the No. 1 support plate 3 and the No. 2 support plate 4 protrude from the reagent kit body 1, thereby making it convenient for the test personnel to take them, and avoiding the test tubes being completely placed inside the reagent kit body 1, making it inconvenient for the test personnel to take them, resulting in unstable taking and then the test tubes being broken.

[0057] Through the above arrangement, on the one hand, interference between the test tube and the cover 2 is avoided, and when the cover 2 is fully opened, the No. 1 support plate 3, the No. 2 support plate 4 and the cover 2 are more stable, so that the position of the test tube is more stable during the process of taking the test tube. On the other hand, when the cover 2 is fully opened, the test tube will protrude from the reagent box body 1, so that it is convenient for the tester to take it, and avoid the test tube being completely placed inside the reagent box body 1, which makes it inconvenient for the tester to take it, resulting in unstable taking and then the test tube breaking.

[0058] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 5、 Figure 6 The pulling assembly is arranged between the first support plate 3 and the second support plate 4, and the pulling assembly can move the second support plate 4 toward the first support plate 3 when the first support plate 3 rises to the highest point of the stroke;

[0059] The pulling assembly includes a deflection rod 11 rotatably connected to the second support plate 4, and a first pulley 10 is rotatably mounted on one end of the deflection rod 11 away from the second support plate 4. The first pulley 10 can roll in a first horizontal groove 9 formed on the side of the first support plate 3;

[0060] The pulling assembly also includes an abutment structure arranged between the side wall of the reagent box body 1 and the deflection rod 11, and the abutment structure includes a second pulley 12 rotatably mounted on the deflection rod 11 and an inclined baffle 13 arranged on the side wall of the reagent box body 1. The second pulley 12 can drive the deflection rod 11 to rotate under the obstruction of the inclined baffle 13.

[0061] When the No. 1 support plate 3 rises, it will drive the No. 2 support plate 4 connected thereto to move upward. At this time, under the action of the gravity of the No. 2 support plate 4, the deflection rod 11 is in a vertical state, and the No. 1 pulley 10 on the deflection rod 11 is at the end of the No. 1 horizontal groove 9. When the No. 1 support plate 3 and the No. 2 support plate 4 move to the end of the stroke, the No. 2 pulley 12 on the deflection rod 11 will abut against the inclined baffle 13. At this time, under the guidance of the inclined baffle 13, the deflection rod 11 will rotate, causing the No. 1 pulley 10 to do a circular motion. When the No. 1 pulley 10 does a circular motion, the No. 1 pulley 10 will move along the length direction of the No. 1 horizontal groove 9, and the No. 2 support plate 4 will move toward the No. 1 support plate 3, so as to move the test tube whose bottom is in contact with the No. 2 support plate 4 toward the upper part of the No. 1 support plate 3, and after the No. 1 support plate 3 and the No. 2 support plate 4 rise to the highest point of the stroke, the No. 1 support plate 3 is in the middle position of the test tube, and the length of the test tube protruding from the No. 1 support plate 3 is longer, so that when the tester takes the test tube, the position for taking is larger, and it is avoided that the test tube is inconvenient to take due to the too small taking part of the test tube or even the test tube is broken due to unstable taking.

[0062] Through the above arrangement, when the No. 1 support plate 3 and the No. 2 support plate 4 are in the reagent box body 1, the No. 1 support plate 3 is at the upper end of the test tube, so that the two ends of the test tube are limited, making the test tube more stable. At the same time, when the No. 1 support plate 3 and the No. 2 support plate 4 move upward, the test tube will move toward the No. 1 support plate 3 under the drive of the No. 2 support plate 4, so that the No. 1 support plate 3 is in the middle position of the test tube, so that when the tester takes the test tube, the position for taking is larger, and it is avoided that the test tube is too small to take the test tube, which causes inconvenience in taking or even the test tube is broken due to unstable taking, further improving the convenience of taking, and avoiding the contamination of antibodies due to the breakage of the test tube.

[0063] See also Figures 2 to 4 The clamping assembly is arranged between the first support plate 3 and the reagent box body 1, and the clamping assembly is connected to an arc-shaped rubber member 20. When the first support plate 3 is lowered to the lowest point of the stroke, the clamping assembly can drive the arc-shaped rubber member 20 to abut against the test tube inserted between the first support plate 3 and the second support plate 4;

[0064] The clamping assembly includes an abutment member 17 slidably disposed on the first support plate 3, the abutment member 17 is fixedly connected to the arc-shaped rubber member 20, and two protruding shafts 18 are symmetrically disposed on both sides of the abutment member 17, and the protruding shafts 18 are adapted to the guide plates 19 disposed on the side walls of the reagent box body 1;

[0065] The guide plate 19 includes an inclined plate 1901 and a vertical plate 1902;

[0066] The clamping assembly further includes an elastic structure connecting the abutment member 17 and the first support plate 3. The elastic structure includes a retardation groove 14 provided on the side of the first support plate 3 and a retardation block 1701 provided on the abutment member 17. The retardation block 1701 is capable of sliding in the retardation groove 14.

[0067] A transverse shaft 15 slidably connected to the hysteresis block 1701 is also installed in the hysteresis groove 14. A cylindrical spring 16 is sleeved on the transverse shaft 15. One end of the cylindrical spring 16 is connected to the inner wall of the hysteresis groove 14, and the other end is connected to the hysteresis block 1701.

[0068] When the test tubes are filled with the through holes 5 and the supporting base 6, the cover plate 2 is closed. At this time, the No. 1 support plate 3 and the No. 2 support plate 4 will move downward. During this process, the distance between the No. 1 support plate 3 and the No. 2 support plate 4 will decrease. At the same time, the test tube will move downward relative to the No. 1 support plate 3 until the No. 1 support plate 3 is at the same height as the upper end of the test tube. Then, as the No. 1 support plate 3 and the No. 2 support plate 4 continue to descend, the convex shaft 18 will abut against the inclined plate 1901, and under the drive of the inclined plate 1901, the abutment 17 moves toward the test tube, compressing the cylindrical spring 16 while making the arc-shaped rubber part 20 abut against the test tube to increase the strength of the test tube being fixed. At the same time, as the No. 1 support plate 3 and the No. 2 support plate 4 continue to move, the convex shaft 18 will slide on the vertical plate 1902 to prevent the abutment 17 from moving excessively and crushing the test tube.

[0069] Through the above arrangement, when the No. 1 support plate 3 and the No. 2 support plate 4 move to the end of the stroke, the abutment member 17 can drive the arc-shaped rubber member 20 to abut against the test tube, thereby improving the strength of the fixation inside the test tube, and avoiding the test tube from shaking due to unstable clamping when the test tube is stored in the reagent kit body 1, and eventually causing breakage and antibody contamination.

[0070] As an embodiment of the present invention, a method for sealing IgM antibodies using the kit is also proposed, comprising the following steps:

[0071] Step 1: Open the cover plate 2, place the solution containing IgM antibodies in the test tube, and seal the end of the test tube with a sterile rubber stopper;

[0072] Step 2: Place the blocked test tubes into the through holes 5 one by one, and make the bottoms of the test tubes contact the supporting base 6;

[0073] Step 3: After the through-holes 5 and the supporting base 6 are filled with test tubes, the cover 2 is closed;

[0074] Step 4: During the closing process of the cover 2, the cover 2 drives the first support plate 3 and the second support plate 4 toward the interior of the reagent box body 1 through the lifting assembly. At the same time, the pulling assembly causes the second support plate 4 to move away from the first support plate 3, and the first support plate 3 to move to a position close to the top of the test tube.

[0075] Step 5: Continue to close the cover 2. When the No. 1 support plate 3 and the No. 2 support plate 4 drop to the end of their travel, the clamping assembly moves, driving the arc-shaped rubber member 20 close to the top of the test tube and abutting against the top of the test tube until the cover 2 is completely closed and the seal is completed.
