Description

Technical Field

[0001] This utility model relates to the field of medical testing equipment technology, and in particular to a sterilization system for internal disinfection of an enzyme-linked immunosorbent assay (ELISA) reader. Background Technology

[0002] Existing ELISA readers use an electric tray to move the detection plate, allowing the sample on the detection plate to enter the reader for absorbance or fluorescence detection. The specific process is controlled by an external computer.

[0003] During this process, external factors may cause liquid to spill from the plate. The opening of the electric tray on the microplate reader is small, making it inconvenient to disinfect and clean. Incomplete disinfection may also cause secondary contamination of subsequent samples and affect subsequent test results. In addition, spillage may form aerosols, and opening the electric tray may affect staff. Utility Model Content

[0004] This invention provides a sterilization system for internal disinfection of ELISA readers, aiming to solve the problems of existing ELISA readers where liquid inside the plate may spill due to external factors, the electric tray has a small opening on the ELISA reader which is inconvenient for disinfection and cleaning, and incomplete disinfection may cause secondary contamination of subsequent samples by the electric tray, affecting subsequent test results.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A sterilization system for internal disinfection of an ELISA reader includes an electric tray movably mounted on the ELISA reader. A detection tray is mounted on the upper limit of the electric tray. The ELISA reader is equipped with a mounting frame located in the mounting cavity at the top of the electric tray. The bottom of the mounting frame is equipped with an identification mechanism and a disinfection mechanism. Both the identification mechanism and the disinfection mechanism are directly opposite the detection tray. The identification mechanism is linked and coordinated with the disinfection mechanism and the electric tray via an external computer.

[0007] Preferably, the disinfection mechanism includes several ultraviolet disinfection lamps, which are arranged at equal intervals on the mounting frame, with the irradiation ends of the ultraviolet disinfection lamps facing the detection plate, and all ultraviolet disinfection lamps are electrically connected to an external computer.

[0008] More preferably, the identification mechanism includes a plurality of miniature identification cameras, which are arranged at equal intervals on the mounting bracket, and the camera ends of the miniature identification cameras are all facing the detection plate. The miniature identification cameras are all electrically connected to an external computer.

[0009] Furthermore, there are at least three ultraviolet disinfection lamps, which are respectively arranged on both sides and in the middle of the mounting frame.

[0010] Furthermore, there are at least two miniature recognition cameras, each positioned in the middle between the ultraviolet disinfection lamps.

[0011] Preferably, the electric tray is provided with four right-angle limiting members, each corresponding to a right angle of the detection tray, and the right angle of the detection tray is embedded in the corresponding limiting member to form a limiting fit.

[0012] More preferably, the outer perimeter of the electric tray is provided with a vertical edge, which is concentric and coaxial with the electric tray.

[0013] The beneficial effects of this utility model are:

[0014] The identification mechanism works in conjunction with the disinfection mechanism and the electric tray via an external computer. When the identification mechanism detects a leak of liquid sample, it activates the disinfection mechanism and locks the electric tray for closed disinfection via the external computer. This prevents aerosols from affecting staff, disinfects exposed areas and aerosols, and forms a pre-disinfection treatment, which facilitates the subsequent disinfection of the electric tray and prevents secondary contamination of subsequent samples.

[0022] The embodiments will be further described below with reference to the accompanying drawings.

[0023] like Figures 1-3As shown in the preferred embodiment 1, a sterilization system for internal disinfection of an ELISA reader includes an electric tray 2 movably mounted on the ELISA reader 1. A detection tray 4 is mounted on the upper limit of the electric tray 2. The ELISA reader 1 has a mounting frame 6 located within a mounting cavity 5 at the top of the electric tray 2. The bottom of the mounting frame 6 has an identification mechanism 7 and a disinfection mechanism 8, both facing the detection tray 4. The identification mechanism 7 is linked to the disinfection mechanism 8 and the electric tray 2 via an external computer 9. When the identification mechanism 7 detects leakage of liquid sample, the external computer 9 activates the disinfection mechanism 8 and locks the electric tray 2 for closed disinfection, preventing secondary contamination caused by movement of the electric tray 2. After one disinfection cycle, the electric tray 2 can be opened and cleaned. After cleaning, the empty tray is pushed back in, and the external computer 9 performs disinfection again to prevent interference with subsequent sample testing and facilitate the disinfection of the electric tray.

[0024] The disinfection mechanism 8 includes several ultraviolet disinfection lamps 801, which are arranged at equal intervals on the mounting frame 6. The irradiation ends of the ultraviolet disinfection lamps 801 are all facing the detection plate 4. The ultraviolet disinfection lamps 801 are all electrically connected to an external computer 9, and disinfection is performed through the ultraviolet disinfection lamps 801.

[0025] The identification mechanism 7 includes several miniature identification cameras 701, which are arranged at equal intervals on the mounting frame 6. The camera ends of the miniature identification cameras 701 are all facing the detection plate 4. The miniature identification cameras 701 are all electrically connected to the external computer 9, and the images are transmitted to the external computer 9 in real time. This is used to identify whether liquid has been spilled and can also be used to monitor the internal detection situation.

[0026] The ultraviolet disinfection lamps 801 are at least three in number, arranged on both sides and in the middle of the mounting frame 6 respectively, to ensure that the disinfection range covers the entire tray. The number of lamps can be increased or decreased as appropriate according to the size of the tray.

[0027] At least two miniature recognition cameras 701 are arranged in the middle between the ultraviolet disinfection lamps 801 to ensure the recognition range and avoid omissions, while not interfering with the ultraviolet disinfection lamps 801.

[0028] As a preferred embodiment 2, the electric tray 2 is provided with four right-angle limiting members 3, and the right angles of the limiting members 3 correspond one-to-one with the right angles of the detection tray 4. The right angles of the detection tray 4 are embedded in the corresponding limiting members 3 and form a limiting fit, which ensures the installation of the detection tray 4, facilitates disassembly and fixed installation, and makes it convenient to clean the electric tray 2.

[0029] In a preferred embodiment 3, the outer periphery of the electric tray 2 is provided with a vertical edge 10, which is concentric and coaxial with the electric tray 2. The vertical edge 10 forms a groove to prevent spilled liquid from flowing into the microplate reader 1 and facilitates cleaning.

[0030] As a preferred embodiment 4, the mounting frame 6 is a grid-shaped mounting frame, and other components inside the ELISA reader can also be mounted on it, as long as they do not interfere with the disinfection mechanism 8 and the identification mechanism 7.

[0031] The working principle of this utility model:

[0032] The identification mechanism 7 of this utility model is linked with the disinfection mechanism 8 and the electric tray 2 through the external computer 9. When the identification mechanism 7 detects that the liquid sample is leaking, the external computer 9 starts the disinfection mechanism 8 and locks the electric tray 2 for closed disinfection to prevent secondary pollution caused by the movement of the electric tray 2.

[0033] After one disinfection cycle, the electric tray 2 can be opened and the entire tray cleaned. After cleaning, the empty tray is pushed in, and the external computer 9 is used for another disinfection to prevent any impact on subsequent sample testing and to facilitate the disinfection of the electric tray.
