Description

Technical Field

[0001] This utility model relates to the field of enzyme-labeled plate cleaning technology, and in particular to a device for efficient cleaning of enzyme-labeled plates. Background Technology

[0002] An ELISA plate is a porous microplate that serves as the core carrier for enzyme-linked immunosorbent assays (ELISA). It is typically made of inert polymers such as polystyrene, with its surface immobilized by physical adsorption or chemical modification of specific antigens or antibodies. This micro-well array structure provides independent reaction sites for biomolecular interactions. The experiment sequentially carries out steps such as sample addition, enzyme label binding, and substrate color development. Qualitative or quantitative analysis of the analyte is achieved through the quantifiable signal generated by enzyme catalysis of the substrate. Its standardized design ensures the homogeneity of the reaction system, and combined with spectroscopic detection equipment, it enables high-throughput screening. It is widely used in clinical diagnostics, biological research, and drug development. During the use of ELISA plates, the cleaning step is crucial for ensuring detection accuracy. By removing unbound free components, background signal interference can be effectively reduced, false positive or false negative results can be avoided, and cross-contamination between wells can be prevented. This ensures the independence of each reaction well and the repeatability of results, ultimately improving the signal-to-noise ratio and data reliability of the detection system.

[0003] Existing ELISA plate cleaning equipment suffers from a liquid switching issue due to the independent piping design of the washing and rinsing systems. This necessitates repeated manual intervention by researchers during the plate washing process. Specifically, when performing the sample washing procedure, researchers must first switch the pure water supply line to a dedicated washing solution delivery channel. Then, during the rinsing phase, they must reverse the process to switch the line back to pure water supply. This dual-liquid-path alternation mechanism involves complex steps such as pipe disassembly and container replacement for each liquid switch, compromising the continuity of the cleaning process and reducing overall cleaning efficiency. Therefore, this paper proposes a device for efficiently cleaning ELISA plates. Utility Model Content

[0021] The following will be combined with the appendix Figure 1 To be continued Figure 4 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] This utility model provides a technical solution: a device for efficiently cleaning ELISA plates, including a cleaning chamber 100 and a cover 300 hinged to the top center of the cleaning chamber 100.

The cleaning chamber 100 contains an ELISA plate body 400, with the front side of the ELISA plate body 400 facing down and the back side facing up, which facilitates rinsing with pure water and washing solution. The device also includes a media switching and circulating rinsing mechanism 200 for rinsing the ELISA plate body 400.

[0023] Specifically, the media switching and cyclic rinsing mechanism 200 includes a reciprocating slide rail 203 located inside the washing tank 100 and below the ELISA plate body 400, and a water tank 204 installed at the bottom of the inner wall of the washing tank 100, corresponding to the position of the reciprocating slide rail 203. A guide rod 212 for correcting the reciprocating slide rail 203 is provided on the inner wall of one end of the reciprocating slide rail 203, and a reciprocating lead screw 213 for reciprocating traction of the reciprocating slide rail 203 is provided on the inner wall of the other end of the reciprocating slide rail 203.

[0025] Specifically, horizontal support plates 101 for supporting the enzyme-labeled plate body 400 are symmetrically installed at both ends of the upper inner wall of the washing box 100, which facilitates the experimenter to place the enzyme-labeled plate body 400 horizontally. A drain port 102 for discharging wastewater is opened through the middle of the bottom of the inner wall of the washing box 100. A drain cover 103 is rotatably installed at the bottom of the outer wall of the washing box 100 and at the position of the drain port 102 via a rotating shaft 104 to seal the drain port 102. The drain cover 103 is made of rubber material.

[0026] Based on the above, this utility model, by setting up a media switching circulation rinsing mechanism 200, utilizes a three-way pipe 208, a pure water shut-off valve 207, and a washing liquid shut-off valve 209 for coordinated control, and employs an independent liquid supply structure for the pure water storage tank 201 and the washing liquid storage tank 202. This enables rapid switching between pure water and washing liquid supply, avoiding manual disassembly of pipelines and container replacement operations, ensuring the continuity of the cleaning process, and solving the problem in existing technologies where repeated manual intervention by experimental personnel is required due to the alternating use of dual liquid paths. Furthermore, by setting up a reciprocating slide rail 203 and a reciprocating lead screw 213, the reciprocating lead screw 213... The reciprocating slide rail 203 is driven to slide back and forth along the axial trajectory of the slide rail guide rod 212, which enables the rinsing nozzle 217 to perform periodic reciprocating motion in the area below the ELISA plate body 400. This ensures that the cleaning medium fully covers all micropores on the front of the ELISA plate, avoiding cleaning dead corners. Furthermore, by setting up a scissor-type telescopic component 218 and a bidirectional screw 219, and by using the knob 215 to adjust the bidirectional screw 219 to drive the two traction sliders 220 to move synchronously, the spacing of the rinsing nozzle 217 can be dynamically adjusted according to the specifications of the ELISA plate body 400, ensuring that the rinsing nozzle 217 always corresponds to the position of the micropores.

[0027] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
