Description

Technical Field

[0001] The present invention relates to the technical field of microplate readers, in particular to a portable microplate reader. Background Art

[0002] An enzyme-linked immunosorbent assay (ELISA) reader is a specialized instrument for enzyme-linked immunosorbent assays (ELISAs), also known as a microplate reader. Their working principles are essentially the same, with a colorimeter at their core, performing analysis using colorimetry.

[0003] In order to facilitate portability, an enzyme-linked reader is provided with an armrest on the housing so that the operator can carry the enzyme-linked reader by the armrest. Currently, the armrest is usually deflectable, and there is no reinforcement component on the housing to reinforce the armrest, which causes the enzyme-linked reader to shake easily when moving, and the precision components in the enzyme-linked reader are easily damaged. In addition, after the reagent tubes are placed in the enzyme-linked reader, the tested and untested reagent tubes cannot be quickly distinguished. When the operator is faced with multiple tested reagent tubes, the operator needs to use label paper to independently mark the tested reagent tubes, which increases the operator's workload and affects the efficiency of the enzyme-linked reader. Summary of the Invention

[0016] 1. The present invention extends the positioning column to the positioning link and the reserved hole, so that the positioning link can initially limit the positioning link connection, and then installs the positioning card and the positioning guide rod, so that the positioning card drives the positioning pressure block to apply pressure to the traction handrail from both sides, so that the traction handrail is always in a vertical state when the microplate reader device body is transported, which can ensure that the microplate reader device body will not tilt during transportation, thereby protecting the internal precision components.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-Figure 5 A portable microplate reader includes a microplate reader device body 1, which includes a detection port, a display screen, and a placement slot. Supplementary instructions: Place the reagent tube to be tested in the detection port, the display screen can display the test results, and the placement slot can be used to place the reagent tube to be tested and the reagent tube after testing. According to the instructions attached Figure 1 As shown, a sealing plate for sealing the placement slot is installed on the pin shaft of the microplate reader device body 1, and the sealing plate is provided with a buckle that cooperates with the microplate reader device body 1, so that the sealing plate can seal and store the internal reagent tube after deflection;

[0027] Connecting rods 16 are rotatably mounted on both sides of the microplate reader device body 1, and a traction handrail 17 is integrally connected between the two connecting rods 16. The operator can use the traction handrail 17 to carry and transport the microplate reader device body 1;

[0028] The main body 1 of the microplate reader is equipped with a positioning assembly for positioning the traction handrail 17;

[0029] Further explanation:

[0030] The positioning assembly includes a positioning card platform 20 fixedly connected to the main body 1 of the microplate reader, and a positioning groove 21 is provided on the positioning card platform 20 to cooperate with the traction handrail 17. The positioning groove 21 guides the traction handrail 17 to limit the deflection angle of the traction handrail 17. A positioning guide rod 22 is detachably installed in the positioning card platform 20, and a positioning card plate 23 is integrally connected between the two positioning guide rods 22;

[0031] A positioning block 24 is fixedly mounted on the positioning card plate 23 and is movably opposed to the traction handrail 17. By installing the positioning guide rod 22 and the positioning card plate 23 in the positioning card platform 20, the positioning card platform 20 can squeeze the traction handrail 17 from both sides, so that the traction handrail 17 will not tilt when in use, and the traction handrail 17 is always in a vertical state when in use.

[0032] A positioning link 18 is fixedly mounted on the connecting rod 16, and a positioning post 19 extending into the inside of the microplate reader device body 1 is detachably mounted on the positioning link 18. A reserved hole corresponding to the positioning post 19 is opened on the microplate reader device body 1, and the positioning card plate 23 and the positioning guide rod 22 extend to the upper end position outside the positioning card table 20;

[0033] When the traction handrail 17 is in a vertical state, the connecting rod 16 drives the positioning link 18 to correspond to the reserved hole, and the positioning link 18 can be limited to a specified position by the positioning column 19, so that the positioning column 19 can achieve preliminary positioning of the connecting rod 16, so that the internal parts will not be damaged when the operator takes the microplate reader device body 1;

[0034] A display component for displaying the inspected reagent tubes is installed in the placement tank;

[0035] Further explanation:

[0036] The display component includes a partition plate 2 fixedly installed in the placement groove, a placement table 3 matched with the reagent tube is fixedly installed in the placement groove, the positioning plate 4 is an arc-shaped structure adapted to the reagent tube, and the placement table 3 is a concave structure, and the positioning plate 4 matched with the reagent tube is integrally connected to the main body 1 of the microplate reader. It is supplemented that when the untested reagent tube is placed on the placement table 3, one side of the reagent tube is movably against the positioning plate 4, so that the untested reagent tube can be easily taken by the operator, which means that the untested reagent tube is in an active state, and the tested reagent tube will cooperate with the pressure plate 7 to achieve limiting, so that the untested reagent tube and the tested reagent tube can be quickly distinguished, so that the operator can take the specified reagent tube when faced with a large number of untested reagent tubes and tested reagent tubes;

[0037] According to the instruction manual Figure 3 As shown, the operator can set up multiple evenly distributed placement tables 3 and positioning plates 4 according to the specifications of the partition plate 2, and use multiple display lights 15 to mark multiple reagent tubes respectively, so that the microplate reader device body 1 can quickly detect the reagent tubes after moving to the designated position;

[0038] A screw rod 5 is rotatably mounted on the partition plate 2, and a matching nut 6 is slidingly sleeved on the screw rod 5. A pressure plate 7 is fixedly mounted on the nut 6, which cooperates with the positioning plate 4 and is used to limit the reagent tube. The screw rod 5 is horizontally arranged on the partition plate 2, and the pressure plate 7 is an arc-shaped structure that cooperates with the reagent tube. By setting the pressure plate 7 as an arc-shaped structure that cooperates with the reagent tube, the contact area between the pressure plate 7 and the reagent tube can be increased. By placing the reagent tube by the platform 3, the positioning plate 4, and the pressure plate 7, it can be ensured that the reagent in the reagent tube will not leak after the limit is formed.

[0039] A driven gear 8 is fixedly mounted on the screw rod 5, and a guide rod 9 is fixedly mounted on the partition plate 2. An active rack 10 is slidably sleeved on the guide rod 9 and meshed with the driven gear 8. The guide rod 9 guides the active rack 10 so that the active rack 10 can mesh with the driven gear 8 smoothly during movement. A spring 11 is welded between the active rack 10 and the partition plate 2.

[0040] The guide rod 9 is vertically arranged, and the spring 11 is vertically welded to the lower end position of the active rack 10 extending outside the guide rod 9. A pressure head 12 is fixedly mounted on the active rack 10, and a connecting plate 13 is rotatably mounted on the partition plate 2. The spring 11 resets the active rack 10. When the pressure head 12 is in an unloaded state, the spring 11 can pull the active rack 10 back to its initial position.

[0041] A pressure sensor 14 is fixedly mounted on the connecting plate 13 and is in contact with the pressure head 12. A display light 15 is provided on the partition plate 2 and is matched with the pressure sensor 14.

[0042] The connecting plate 13 is manually rotated so that the connecting plate 13 drives the pressure sensor 14 to move against the pressure head 12. When the pressure head 12 is pressed downward, the pressure plate 7 can limit the reagent tube. The pressure sensor 14 is pressed by the pressure head 12 and the display light 15 is turned on immediately, so that the display light 15 can remind the operator that the reagent tube has been tested, making it more convenient for the operator to take the untested reagent tube, thereby improving the efficiency of the use of the microplate reader device body 1, avoiding multiple tests on a single reagent tube, and thus improving the detection accuracy;

[0043] It should be noted that the specific models and specifications of the microplate reader device body 1, pressure sensor 14, and display light 15 need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0044] The present invention can be explained through the following operation mode:

[0045] When the traction handrail 17 is needed to carry the microplate reader device body 1;

[0046] Manually pull the traction handrail 17 to deflect it, so that the traction handrail 17 drives the connecting rod 16 to rotate on the microplate reader device body 1. When the connecting rod 16 rotates, it drives the traction handrail 17 to slide in the positioning groove 21, so that the traction handrail 17 is in a vertical state;

[0047] When the traction handrail 17 is in a vertical state, the positioning link 18 corresponds to the reserved hole, and the operator extends the positioning column 19 through the positioning link 18 into the reserved hole to preliminarily limit the connecting rod 16;

[0048] Press the positioning card plate 23 so that the positioning card plate 23 drives the positioning guide rod 22 to extend into the positioning card platform 20. The positioning card plate 23 drives the positioning pressure block 24 to resist the two sides of the traction handrail 17, so that the traction handrail 17 is always in a vertical state.

[0049] The operator places the reagent tube in the test port for testing, and the display screen can display the test results. When the test of the reagent tube is completed, it is placed on the placement table 3 so that one side of the reagent tube is movably against the positioning plate 4;

[0050] The pressure head 12 is pressed, so that the pressure head 12 drives the active rack 10 to slide on the guide rod 9. The spring 11 is stressed, so that the active rack 10 cooperates with the driven gear 8 in meshing connection when moving, and drives the screw rod 5 to rotate. When the screw rod 5 rotates, it drives the nut 6 to slide horizontally. When the nut 6 slides, it drives the pressure plate 7 to squeeze and limit one side of the reagent tube;

[0051] At the same time, the connecting plate 13 is manually pulled and rotated, so that the connecting plate 13 drives the pressure sensor 14 and the pressure head 12 to move against each other during rotation. When the pressure sensor 14 is squeezed by the pressure head 12, the indicator light 15 lights up immediately.

[0052] Repeat the above steps and the detected reagent tube can be displayed by the display light 15.

[0053] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
