AI Technical Summary

Technical Problem

Existing ELISA strip devices are heavy, easily contaminated, and individual or multiple strips can fall off and become unstable on the ELISA plate. They are also prone to falling off and disrupting the sample order during plate washing and other operations.

Method used

Design an auxiliary device for fixing detachable enzyme-labeled strips, including a base plate and a top plate, which are connected by a non-detachable connecting strap. The device utilizes a positioning mechanism and a positioning groove to achieve convenient disassembly and secure installation. The device combines a positioning column and a top rod to improve stability and includes hydrophobic holes to drain accumulated liquid.

Benefits of technology

This technology ensures that the enzyme-labeled strips are less likely to fall off during the plate washing process, avoids sample sequence disorder, and improves operational convenience and anti-contamination effect.

Abstract

This utility model belongs to the field of enzyme-linked immunosorbent assay (ELISA) strips, specifically an auxiliary device for fixing detachable ELISA strips. It includes a base plate with a top plate on one side. Both the base plate and the top plate have connecting holes. A positioning mechanism is provided on one side of the base plate. This utility model connects the base plate to the base plate via a non-detachable connecting strap and achieves fixation through multiple positioning mechanisms. Both the first and second fixing blocks serve as connectors. An insert plate on the first fixing block engages with a corresponding insert. During insertion, the insert plate compresses an elastic locking block. When the elastic locking block aligns with the positioning groove, it pops out and engages. This achieves convenient disassembly and reassembly of the base plate and top plate while ensuring stability, minimizing the risk of detachment during plate washing. It also prevents the ELISA strip from falling off during washing, swiping, and other operations, which could lead to confusion in the sample order.
