Description

Technical Field

[0001] This utility model relates to the field of enzyme-linked immunosorbent assay (ELISA) reader technology, specifically to an ELISA reader with a cleaning function. Background Technology

[0002] An ELISA reader is a laboratory instrument used to measure the concentration of specific substances in liquid samples. It primarily performs quantitative analysis by detecting signals such as light absorption, fluorescence, or chemiluminescence, and is widely used in life sciences, medical diagnostics, and food safety testing. When testing liquid samples, ELISA readers require a dispenser and a syringe to transfer different liquids into the ELISA plate tank. However, during this process, some liquid tends to drip onto the top of the plate. Due to the fluidity of the liquid, different types of samples that have stagnated at the top of the plate can mix together, leading to insufficient accuracy in sample testing. Therefore, patent number […].

[0003] CN202323046368.5 discloses an ELISA reader. This design involves setting a support at the detection port of the ELISA reader, with a sponge at the bottom of the support. The sponge cleans the ELISA plate. However, since the sponge is reused, it easily accumulates a lot of dirt, which affects the cleaning effect. This design does not allow for quick replacement of the sponge, impacting practical use. Furthermore, the sponge frequently wipes samples, resulting in high moisture content. The ELISA reader lacks a drying mechanism for the sponge, thus requiring improvement. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an enzyme-linked immunosorbent assay (ELISA) reader with a cleaning function. By incorporating a vacuum pump, pipes, valves, rigid tubes, and vacuum suction heads within the cleaning mechanism, and fixing a rubber sheet to the upper surface of the sponge, the rubber sheet can adhere to the vacuum suction head, thereby enabling quick assembly and disassembly of the sponge and facilitating sponge replacement. This solves the problem of inconvenient sponge replacement in current devices.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] An ELISA reader with a cleaning function includes an ELISA reader body with a detection port on one side. A limiting plate is fixedly connected to the ELISA reader body on the side of the detection port, and an ELISA plate is slidably connected to the limiting plate. A hidden groove is opened on one side of the ELISA reader body, and an L-shaped track frame is fixedly connected to the hidden groove. A cleaning mechanism for cleaning the ELISA plate is slidably connected to the track frame. The cleaning mechanism includes: an L-shaped plate slidably connected to the track frame; a rigid tube fixedly connected to the lower surface of the L-shaped plate, and the bottom of the rigid tube is connected to equidistantly distributed vacuum suction heads; and a sponge with a rubber sheet fixedly connected to the upper surface of the sponge, the rubber sheet adsorbing onto the vacuum suction heads.

[0009] Furthermore, sliding blocks are fixedly connected to both sides of the L-shaped plate, and the L-shaped plate is slidably connected to the track frame through the sliding blocks.

[0010] Furthermore, a vacuum pump is mounted on the L-shaped plate, and a pipe is connected between one side of the vacuum pump and the rigid pipe, with a valve installed on the pipe.

[0011] Furthermore, a handle is fixedly connected to one side of the L-shaped plate.

[0012] Furthermore, a heating plate is fixedly connected to the hidden slot of the main body of the ELISA reader.

[0013] Furthermore, a control panel is installed on one side of the main body of the microplate reader, and the control panel is equipped with a power interface and a drying switch, wherein the drying switch is connected in series with the heating plate.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides an ELISA reader with a cleaning function, which has the following beneficial effects:

[0016] 1. This utility model, through the setting of a cleaning mechanism, includes an L-shaped plate, a rigid tube, a vacuum suction head, a valve, a pipe, a vacuum pump, a sponge, and a rubber sheet, etc., wherein the rubber sheet is fixedly connected to the upper surface of the sponge and is detachably adsorbed onto the vacuum suction head. During use, the vacuum pump generates a negative pressure, and the negative pressure of the vacuum suction head adsorbs the rubber sheet, thereby fixing the rubber sheet and the sponge. When the sponge needs to be replaced, the vacuum pump can be used to release air, thereby canceling the adsorption and fixing effect of the rubber sheet and the sponge, thus realizing quick sponge replacement. It is very convenient to use and facilitates sponge replacement in practical applications.

[0023] Example

[0024] like Figure 1 and Figure 3As shown in the figure, an embodiment of the present invention provides an ELISA reader with a cleaning function, including an ELISA reader body 1 with a detection port 2 on one side. A limiting plate 4 is fixedly connected to the ELISA reader body 1 on the side of the detection port 2, and an ELISA plate 3 is slidably connected to the limiting plate 4. The detection port 2 is provided to push the ELISA plate 3 into the interior of the ELISA reader body 1, thereby detecting the sample on the ELISA plate 3. The limiting plate 4 is fixedly connected to the ELISA reader body 1 to limit the sliding of the ELISA plate 3. The ELISA plate 3 is used to hold the sample, thereby realizing the sample detection. A hidden groove 6 is opened on one side of the ELISA reader body 1, and a U-shaped track frame 7 is fixedly connected to the hidden groove 6 of the ELISA reader body 1. A cleaning mechanism 5 for cleaning the ELISA plate 3 is slidably connected to the track frame 7. The hidden groove 6 is provided to hide and house the cleaning mechanism 5. When cleaning is not required, it is stored in the hidden groove 6. When storing samples, the samples are easy to drip onto the ELISA plate 3, therefore... The cleaning mechanism 5 cleans the ELISA plate 3. The cleaning mechanism 5 includes an L-shaped plate 501, which is slidably connected to the track frame 7, allowing the L-shaped plate 501 to extend and retract, and to clean the ELISA plate 3 during the extension and retraction movement; a rigid tube 504, which is fixedly connected to the lower surface of the L-shaped plate 501, and the bottom of the rigid tube 504 is connected to equidistantly distributed vacuum pipette tips 505; and a sponge 509, on the upper surface of which a rubber sheet 5010 is fixedly connected, which is adsorbed onto the vacuum pipette tips 505. The rigid tube 504 can evacuate the vacuum pipette tips 505, thereby creating a vacuum adsorption effect to adsorb and fix the rubber sheet 5010, thus achieving the adsorption and fixation of the sponge 509. When gas enters the rigid tube 504, the adsorption effect of the vacuum pipette tips 505 is canceled, and the sponge 509 can be removed, thus achieving quick disassembly and assembly of the sponge 509 and facilitating the replacement of the sponge 509.

The vacuum pump 508 can perform a vacuuming function, and a pipe 507 is connected between one side of the vacuum pump 508 and the rigid pipe 504. A valve 506 is installed on the pipe 507, and the valve 506 controls the airflow state of the pipe 507. The vacuum pump 508 can evacuate the rigid pipe 504 through the pipe 507, forming a vacuuming effect between the rigid pipe 504 and the vacuum suction head 505, thereby adsorbing and fixing the rubber sheet 5010. When it is necessary to remove the sponge 509, simply open the valve 506. The operation is very convenient.
