Description

Technical Field

[0001] This utility model relates to the field of enzyme-linked immunosorbent assay (ELISA) reader technology, and specifically to an ELISA reader pretreatment rinsing device. Background Technology

[0002] An enzyme-linked immunosorbent assay (ELISA) reader is a specialized instrument for enzyme-linked immunosorbent assays, also known as a microplate reader.

[0003] Currently, plastic microplates are typically used to hold the samples to be tested. The plastic microplates are then placed on a tray inside the microplate reader. During each placement and removal of the plastic microplate, the sample may be scattered on the tray, which may affect the subsequent examination of the sample and thus affect the accuracy of the test data.

[0004] To address the aforementioned issues, this application proposes a pretreatment rinsing device for an ELISA reader. Utility Model Content

A placement slot 205 is provided on the instrument body 1. A water tank 206 and a water pump 209 are installed on the instrument body 1 through the placement slot 205. A first water pipe 210 connected to the inside of the water tank 206 is installed at the input end of the water pump 209, and a second water pipe 211 is installed at the output end of the water pump 209. One end of the second water pipe 211 is connected to a square pipe 212 located inside the instrument body 1. The bottom of the square pipe 212... The instrument body 1 is equipped with multiple nozzles 213, and the water outlets of the nozzles 213 are all located in the pretreatment tank 201. The instrument body 1 is provided with a storage tank 214, and a storage box 215 is inserted into the instrument body 1 through the storage tank 214. The top of the storage box 215 is connected to a flexible hose 217 that is connected to the pretreatment tank 201. According to the above technical solution, specifically, by removing the tray 103 and inserting it into the pretreatment tank 201, and then installing the mounting plate 203, the water pump 209 is started to introduce the water in the water tank 206 into the second water pipe 211 through the first water pipe 210, and then into the square pipe 212 through the second water pipe 211. The water is then sprayed out through the nozzles 213 to rinse the surface of the tray 103. Subsequently, the wastewater flows into the storage box 215 through the flexible hose 217, thereby achieving the effect of pre-rinsing the tray 103 and minimizing the impact of residual specimens on the accuracy of subsequent specimen testing.

An oblique hole 218 communicating with the pretreatment tank 201 is opened on one side of the instrument body 1. A negative pressure fan 219 is installed at the end of the oblique hole 218 away from the pretreatment tank 201. When the electric heater 220 is turned on, it is used to heat the pretreatment tank 201. Then, the negative pressure fan 219 is turned on to extract the water vapor generated in the pretreatment tank 201, which achieves the effect of drying the tray 103 and helps to make the tray 103 usable more quickly.

[0033] Working principle:

[0034] The pretreatment rinsing device for this ELISA reader works by removing the tray 103 and inserting it into the pretreatment tank 201, then installing the mounting plate 203, and then starting the water pump 209 to introduce water from the water tank 206 into the second water pipe 211 through the first water pipe 210, and then into the square pipe 212 through the second water pipe 211. The water is then sprayed out through the nozzle 213 to rinse the surface of the tray 103. Subsequently, the wastewater flows into the collection box 215 through the hose 217, thereby achieving the effect of pre-rinsing the tray 103 and minimizing the impact of residual samples on the accuracy of subsequent sample testing.

[0035] The pretreatment rinsing device of the ELISA reader is started by an electric heater 220 to heat the pretreatment tank 201. Then, the negative pressure fan 219 is started to extract the water vapor generated in the pretreatment tank 201, which achieves the effect of drying the tray 103 and helps to make the tray 103 usable more quickly.
