Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an immune detection device for rheumatoid arthritis. Background Technology

[0002] Rheumatoid arthritis is a chronic autoimmune disease, and it is usually diagnosed using rheumatoid factor. When the serum to be tested is added to a suspension of latex particles, if the serum contains rheumatoid factor, it will react with denatured IgG molecules on the surface of the latex particles to form visible agglutination particles. By observing the agglutination, it can be determined whether the serum to be tested contains rheumatoid factor.

[0003] However, existing immunoassays for rheumatoid arthritis typically involve adding serum to a test tube containing a latex particle suspension and then either letting it stand or having it manually shaken by medical staff. Both methods have drawbacks: when the test tube is left to stand, the serum may mix with the latex particle suspension without dissolving, and the reaction is slow. On the other hand, manual shaking by medical staff is not only physically demanding, but also makes it difficult to control the speed, easily causing the agglomerated particles in the test tube to disperse, thus affecting the accuracy of the test.

[0004] To address this technical problem, this invention proposes an immune detection device for rheumatoid arthritis. Utility Model Content

[0005] The main objective of this invention is to provide an immune detection device for rheumatoid arthritis, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An immunoassay device for rheumatoid arthritis includes a rotating plate, a fixed tube connected to the upper end of the rotating plate, a fixed rod connected to the upper end of the fixed tube, a rotating ball connected to the upper end of the fixed rod, test tubes disposed inside the rotating ball and the fixed tube, a fixed ring disposed at the outer end of the rotating ball, a connecting rod connected to the outer end of the fixed ring, a servo motor connected to the lower end of the rotating plate, a support frame disposed at the outer end of the servo motor, a support ring connected to the outer end of the support frame, and a transparent glass cover connected to the upper end of the support ring.

[0008] Preferably, the rotating plate is located at the upper end of the support frame, the rotating plate is located inside the transparent glass cover, the fixing tube is inclined and has a cotton pad inside, the fixing rod is inclined, and the rotating ball has a cotton pad inside.

[0009] Preferably, the fixing ring is located on the center line of the rotating plate, the fixing ring is slidably connected to the rotating ball, the upper end of the test tube is provided with a stopper, and the side end of the connecting rod is connected inside the transparent glass cover.

[0010] Preferably, the servo motor drive end is connected to the center point of the rotating plate, the lower end of the support frame is connected to a base plate, the lower end of the base plate is provided with an anti-slip groove, the outer end of the base plate is provided with a control panel, and the control panel is connected to the servo motor through a wire.

[0011] Preferably, a battery block is connected inside the base plate, the battery block is located at the lower end of the servo motor, the battery block and the servo motor are connected by wires, a support plate is connected inside the base plate, and the servo motor is connected inside the support plate.

[0012] Preferably, the upper end of the support frame is connected to a lower connecting ring, the lower end of the rotating plate is connected to an upper connecting ring, the lower connecting ring is located below the upper connecting ring, and both have annular grooves inside, in which ball bearings are disposed.

[0013] Preferably, a protective plate is connected to the outer end of the transparent glass cover, a light is installed inside the protective plate, the inner wall of the protective plate is smooth and can reflect light, a protective cover is connected to the upper end of the transparent glass cover, and the test tube is located at the lower end of the protective cover.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, a fixed ring and a rotating plate are provided. Starting a servo motor will drive the rotating plate to rotate (at a slow speed). The rotation of the rotating plate will drive the fixed tube and the rotating ball to rotate, thus slowly shaking the test tubes placed inside. This promotes the contact and mixing of antigens and antibodies. Furthermore, the slow shaking prevents the dispersion of agglomerated particles formed during the reaction. This not only effectively reduces the workload of medical staff and speeds up the reaction, but also helps to evenly mix the antigens and antibodies in the test tubes, ensuring uniform distribution and reducing detection errors.

[0016] In this invention, by providing a light, after the antigen and antibody have reacted in the test tube for a period of time, the servo motor can be stopped, allowing the test tube to stop horizontally in front of the light. The light is then turned on to illuminate the inside of the test tube. Because the aggregated particles have poor light transmittance, they will appear as black dots under the light, making it easier for medical staff to observe them. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-7 As shown, an immunoassay device for rheumatoid arthritis includes a rotating plate 1, a fixed tube 2 connected to the upper end of the rotating plate 1, a fixed rod 3 connected to the upper end of the fixed tube 2, and a rotating ball 4 connected to the upper end of the fixed rod 3. A test tube 5 is placed inside the rotating ball 4 and the fixed tube 2. The test tube 5 contains patient serum and latex particle suspension, as well as antibodies and antigens. A stopper is provided at the upper end of the test tube 5 to prevent the solution from overflowing. The fixed tube 2 is tilted and has a cotton pad inside. A cotton pad is also provided inside the rotating ball 4 to protect the test tube 5 from impact. When the rotating plate 1 rotates, the rotating ball 4 is driven by the fixed rod 3, not the test tube 5, thus avoiding forces within the test tube 5 and protecting it.

[0027] A fixing ring 6 is provided at the outer end of the rotating ball 4. The fixing ring 6 is located on the center line of the rotating plate 1. The fixing ring 6 is used to support and constrain the rotating ball 4 so that it can only rotate within the fixing ring 6. A connecting rod 7 is connected to the outer end of the fixing ring 6. The connecting rod 7 is used to support the fixing ring 6. A servo motor 8 is connected to the lower end of the rotating plate 1.

[0029] A protective plate 19 is connected to the outer end of the transparent glass cover 11. A lamp 20 is installed inside the protective plate 19. The inner wall of the protective plate 19 is smooth and can reflect light, thereby improving the irradiation effect of the lamp 20. When the lamp 20 is turned on, it can irradiate the test tube 5. Due to the high density and poor light transmittance of the aggregated particles, they will appear as black dots under the light, which makes it easier for medical staff to observe. A protective cover 21 is connected to the upper end of the transparent glass cover 11, and the test tube 5 is located at the lower end of the protective cover 21.

[0030] A base plate 12 is connected to the lower end of the support frame 9. The lower end of the base plate 12 has an anti-slip groove to increase the friction between the base plate 12 and the ground or tabletop, thereby improving the stability of the device. A control panel 13 is provided on the outer end of the base plate 12. The control panel 13 is connected to the servo motor 8 through a wire, so that the rotation of the servo motor 8 can be controlled through the control panel 13. A battery block 14 is connected inside the base plate 12. The battery block 14 is located below the servo motor 8 and is connected to the servo motor 8 through a wire. The battery block 14 is used to provide power to the servo motor 8. A support plate 15 is connected inside the base plate 12. The servo motor 8 is connected inside the support plate 15, and the support plate 15 is used to support and fix the servo motor 8.

[0031] The upper end of the support frame 9 is connected to a lower connecting ring 16, and the lower end of the rotating plate 1 is connected to an upper connecting ring 17. The lower connecting ring 16 is located below the upper connecting ring 17. Both have annular grooves inside, and ball bearings 18 are provided in the annular grooves. The ball bearings 18 facilitate the rotation of the rotating plate 1, and the weight of the rotating plate 1 will be applied to the support frame 9, so as not to put pressure on the servo motor 8, thereby ensuring the stable rotation of the servo motor 8.
