Description

Technical Field

[0001] This utility model relates to the technical field of blood coagulation test devices, specifically to a reaction plate tilt control device for blood coagulation tests. Background Technology

[0002] Certain viruses and the hemagglutinin on their surface can cause agglutination of red blood cells in humans or some animals. This agglutination phenomenon is called hemagglutination (HA), also known as direct hemagglutination reaction. The hemagglutination test can determine the presence of hemagglutinating viruses or the hemagglutination titer of the virus. A V-shaped reaction plate is required when performing the hemagglutination test.

[0003] In the hemagglutination test, different dilutions of virus solution are first added to several wells on a V-shaped reaction plate, and then the virus solution is mixed with a suspension of red blood cells. After waiting for a period of time, the operator tilts the V-shaped reaction plate at a 45-degree angle and observes the morphology of the red blood cells that have settled at the bottom of the tube to determine whether the red blood cells have been agglutinated by the virus.

[0004] Currently, even after tilting the V-shaped reaction plate at a 45-degree angle, the operator still needs to hold it with both hands. This method is not only very physically demanding, but if the operator does not hold the V-shaped reaction plate firmly, the virus solution and red blood cell suspension will spill onto the outside of the V-shaped reaction plate, causing contamination.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.

[0020] Example 1

[0021] Please see Figure 1-12 This utility model provides a technical solution: a tilt control device for a reaction plate in a blood coagulation test, comprising a support frame 1, a movable frame 2, a positioning plate 3, and a first limiting component 4. Please refer to [link / reference]. Figure 4 and Figure 6-7 The inner wall of the movable frame 2 is provided with an assembly groove 21, into which the V-shaped reaction plate 8 can be installed. The positioning plate 3 is fixedly connected to the support frame 1, and the included angle between the positioning plate 3 and the top surface of the movable frame 2 is 45°. (See also...) Figure 2-5The first limiting component 4 includes a push plate 41, an insert plate 42, and a guide block 43. The bottom of the guide block 43 extends into the slide rail 11 and can slide along the slide rail 11. When the operator pushes the movable frame 2 to rotate until the top surface of the movable frame 2 is in contact with the bottom surface of the positioning plate 3, the limiting groove 22 on the outer wall of the movable frame 2 is exactly in the corresponding position with the insert plate 42. Next, the operator only needs to push the push plate 41 closer to the movable frame 2, and the insert plate 42 can extend into the limiting groove 22. The movable frame 2 is then restricted and remains in a 45° tilt state. Therefore, the V-shaped reaction plate 8 in the assembly groove 21 also remains in a 45° tilt state.

[0022] Please see Figure 9 In this embodiment, the V-shaped reaction plate 8 is selected as a 96-well reaction plate with 8 rows and 12 columns. Please refer to [link / reference]. Figure 3-7 The guide block 43 has an inverted T-shaped structure, and the shape of the slide 11 matches the shape of the guide block 43, so the push plate 41 will not tip over during movement. There are several insert plates 42 and several limiting grooves 22. Several insert plates 42 and several limiting grooves 22 are evenly distributed on the upper and lower sides of the assembly groove 21. Several insert plates 42 can share the pressure of the movable frame 2.

[0023] Please see Figure 1 In this embodiment, both the positioning plate 3 and the first limiting component 4 are located on the left side of the support frame 1, thus facilitating testing for right-handed operators. In other embodiments, the positioning plate 3 and the first limiting component 4 may also be located on the right side of the support frame 1.

[0024] This invention can be used for blood coagulation tests. The operating steps for the blood coagulation test are as follows: Step 1: Use a micropipette to add 25 μL of physiological saline to each well of the V-shaped reaction plate 8 from left to right.

[0025] Step 2: Add 25 μL of virus solution to the well in column 1 on the left, mix well, and then aspirate 25 μL to the well in column 2 on the left. Serially dilute this amount up to well 10, and discard 25 μL at a time. Wells in columns 11 and 12 are for red blood cell controls.

[0026] Step 3: Add 25 μL of 1% chicken red blood cell suspension to each well from right to left, place the V-shaped reaction plate 8 on a shaker and shake, then place the V-shaped reaction plate 8 in a 37°C constant temperature incubator for 15 minutes and then take it out.

[0027] Step 4: Please refer to Figure 9 First, place the V-shaped reaction plate 8 on one side of the open end of the movable frame 2, then push the bottom convex edge of the V-shaped reaction plate 8 into the assembly slot 21 in the direction indicated by the arrow. Please refer to... Figure 10Next, the operator slowly rotates the movable frame 2 upwards with their right hand. The V-shaped reaction plate 8 will not vibrate, and the virus solution and red blood cell suspension will not spill out. When the top surface of the movable frame 2 is in contact with the bottom surface of the positioning plate 3, the operator pushes the push plate 41 closer to the movable frame 2 with their left hand. The insert plate 42 extends into the limiting groove 22 to restrict the movable frame 2. At this time, the movable frame 2 and the V-shaped reaction plate 8 remain tilted at 45°.

[0028] Step 5: Determine the results. If the red blood cells at the bottom of the tube flow downwards in a linear pattern and settle, it indicates that the red blood cells have not been or are not completely agglutinated by the virus. If the red blood cells at the bottom of the well are spread out and form a uniform thin layer, and do not flow after tilting, it indicates that the red blood cells have been agglutinated by the virus.

[0029] Please see Figure 3 After the result determination is completed, the operator pulls the pull ring on the push plate 41, which will move the push plate 41 away from the movable frame 2. After the insert plate 42 leaves the limit groove 22, the movable frame 2 is released. The operator can control the movable frame 2 to slowly rotate in the opposite direction to a horizontal state, and then remove the V-shaped reaction plate 8.

[0030] Example 2

[0031] This invention can also be used in the hemagglutination inhibition test. Hemagglutination inhibition refers to the addition of a specific antibody to a viral suspension, and the amount of this antibody being sufficient to inhibit viral particles or their hemagglutinin. At this time, the receptors on the surface of red blood cells cannot come into contact with the viral particles or their hemagglutinin, and a hemagglutination inhibition reaction (HI) will occur. At this time, the aggregation of red blood cells is inhibited.

[0032] The procedure for the blood coagulation inhibition test is as follows: Step 1: Using a micropipette, add 25 μL of physiological saline to the wells in columns 1-10 from left to right on the V-shaped reaction plate 8. Add 50 μL of physiological saline to the well in column 11.

[0033] Step 2: Using a micropipette, take 25 μL of the serum sample and place it in well 1, mixing thoroughly. Then, carefully transfer 25 μL of the liquid from well 1 to well 2, and continue this dilution process until well 10. Finally, discard 25 μL of the liquid from well 10. The dilution ratio of the serum sample should be from 1:2 to 1:1024. Well 11 is for red blood cell control, and well 12 is for antigen control.

[0034] Step 3: Add 25 μL of virus solution containing four hemagglutination units to each well up to well 10. A hemagglutination unit (HAunit, HAU) is the highest dilution of the antigen that causes complete agglutination of red blood cells; it is the hemagglutination titer of the antigen, and is measured in units of one hemagglutination unit (HAU). Well 11 is the red blood cell control well, without virus solution; well 12 is the antigen control well, with virus solution added.

[0035] Step 4: Place the V-shaped reaction plate 8 on the shaker, shake for 1-2 minutes, and then let it stand at 37°C for 20 minutes.

[0036] Step 5: Add 50 μL of 1.0% red blood cell suspension to each well, shake on a shaker for 1-2 minutes to mix, and then place the V-shaped reaction plate 8 into a 37°C constant temperature incubator for 20 minutes before taking it out.

[0037] Step 6: Install the V-shaped reaction plate 8 into the assembly slot 21, and then slowly rotate the movable frame 2 upwards until the top surface of the movable frame 2 is in contact with the bottom surface of the positioning plate 3. Next, the operator uses their left hand to push the push plate 41 close to the movable frame 2, and the insert plate 42 extends into the limiting slot 22 to restrict the movable frame 2. At this time, the movable frame 2 and the V-shaped reaction plate 8 remain tilted at 45°.

[0038] Step 7: Result Interpretation. If the red blood cells at the bottom of the tube flow downwards in a linear pattern and settle, it indicates that the red blood cells have not been or are not completely agglutinated by the virus. If the red blood cells at the bottom of the well are spread evenly, forming a uniform thin layer, and do not flow after tilting, it indicates that the red blood cells have been agglutinated by the virus. Criteria for Result Validation: Red Blood Cell Control Wells: No Autoagglutination. Virus Antigen Control Wells: Agglutination.

[0039] This invention not only saves the operator's physical strength but also maintains the stability of the V-shaped reaction plate 8. When the V-shaped reaction plate 8 is held at a 45° tilt, the virus solution and red blood cell suspension will not spill out, thus preventing contamination. Since it is not necessary to manually maintain the tilt of the V-shaped reaction plate 8, sufficient tilting time and a constant tilt angle can be ensured, resulting in more accurate judgment results without deviation.

[0040] Example 3

[0041] Please see Figure 1 and Figure 6-7 Each end of the movable frame 2 is provided with a second limiting component 5, and the structures of the two second limiting components 5 are mirror-symmetrical. Please refer to Figure 8 The second limiting component 5 includes two partitions 51, a rotating shaft 53, and a limiting plate 54. (See also...) Figure 1 and Figure 9-10 An assembly channel 52 is formed between the two partitions 51. A stop plane 541 is provided on the side wall of the limiting plate 54 near the assembly groove 21. The partition 51 is provided with a snap-fit ​​groove 511 that matches the second arc-shaped surface 543. The limiting plate 54 is also provided with a snap-fit ​​block 542 and a lever 544.

[0042] When the operator moves lever 544, causing the limiting plate 54 to leave the assembly channel 52, the locking block 542 disengages from the locking groove 511. At this time, the front opening of the assembly groove 21 is exposed, and the second limiting component 5 is in the open state. The operator can push the bottom convex edge of the V-shaped reaction plate 8 into the assembly groove 21. Next, the operator reverses the lever 544, causing the limiting plate 54 to re-enter the assembly channel 52, and the locking block 542 enters the locking groove 511. The limiting plate 54 cannot move freely, and the limiting component is in the closed state. At this time, the stop plane 541 is in contact with the bottom convex edge of the V-shaped reaction plate 8, and the V-shaped reaction plate 8 cannot move within the assembly groove 21. Therefore, it can be ensured that the V-shaped reaction plate 8 will not detach from the movable frame 2 during the blood coagulation test or blood coagulation inhibition test.

[0043] Please see Figure 8 and Figure 10 Both partitions 51 are provided with a first arc-shaped surface 512, and the limiting plate 54 is provided with a second arc-shaped surface 543. When the limiting assembly is in the closed state, the limiting plate 54 can be completely retracted into the assembly channel 52. The second arc-shaped surface 543 is flush with the first arc-shaped surface 512, and the bottom surface of the lever 544 is flush with the bottom surface of the movable frame 2 to prevent the limiting plate 54 and the lever 544 from scratching other objects.

[0044] Please see Figure 1-2 and Figure 6 The support frame 1 is a C-shaped frame, and the movable frame 2 is located inside the support frame 1. The movable frame 2 is equipped with a handle 23. When the V-shaped reaction plate 8 is installed into the assembly slot 21 and the limiting component is in the closed state, the operator can lift the handle 23 with their right hand, causing the movable frame 2 and the V-shaped reaction plate 8 to rotate together until they tilt to 45°, at which point the movable frame 2 is restrained by the first limiting component 4. There is a gap between the end of the support frame 1 near the handle 23 and the handle 23, so the operator's right hand will not collide with the support frame 1.

[0045] Please see Figure 1-3 and Figure 9 The bottom surface of the support frame 1 is provided with a stop plate 12. The stop plate 12 restricts the rotation range of the movable frame 2, ensuring that the top surface of the movable frame 2 is always flush with the top surface of the support frame 1 in its natural state. Please refer to [link / reference]. Figure 4 and Figure 7 Both the bottom surface of the support frame 1 and the bottom surface of the movable frame 2 are provided with several support legs 6, which allow sufficient clearance between the bottom of the support frame 1 and the movable frame 2. When the operator installs the V-shaped reaction plate 8 into the assembly slot 21, the operator's fingers can reach under the movable frame 2 without being squeezed. Example 4

[0046] Please see Figure 1 and Figure 9-12 This utility model also includes a positioning assembly 7, which includes a positioning frame 71 and an electric telescopic rod 72, the electric telescopic rod 72 being fixedly mounted on the positioning frame 71. Please refer to [link / reference]. Figure 3 and Figure 11 A protruding plate 13 is fixedly installed on the outer wall of the support frame 1. The output end of the electric telescopic rod 72 faces downward and is fixedly connected to the top surface of the protruding plate 13. Please refer to [link / reference]. Figure 1 and Figure 11-12 When the electric telescopic rod 72 is shortened, it can drive the support frame 1, the movable frame 2, the positioning plate 3 and the V-shaped reaction plate 8 to move upward together. During this process, the stop plate 12 can support the movable frame 2.

[0047] Please see Figure 12 Since the V-shaped reaction plate 8 has been moved to a higher position, the operator can easily observe the aggregation of red blood cells in the holes at the bottom of the V-shaped reaction plate 8 without changing their posture. The position of the V-shaped reaction plate 8 can be adjusted at will using the electric telescopic rod 72, making this invention suitable for operators of different heights.

[0048] Please see Figure 12 The adjustment frame 71 includes a first assembly plate 711, a second assembly plate 712, and a handle 713, which is fixedly disposed between the first assembly plate 711 and the second assembly plate 712. A counterweight (not shown in the figure) is provided inside the second assembly plate 712, thus ensuring the stability of the adjustment frame 71 and preventing it from tipping over. Please refer to [link to relevant documentation]. Figure 1 and Figure 12 The adjustment frame 71 and the positioning plate 3 are located on the same side, and the handle 713 has a circular cross-section. When the operator lifts the handle 23 with his right hand, his right hand will not collide with the adjustment frame 71. At the same time, the handle 713 has sufficient length so that the operator's left hand can hold the handle 713, further increasing the stability of this utility model.

[0049] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the ideas of this technical content. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this patent.
