Multi-reagent encapsulation of cuvette

Abstract

The invention discloses an encapsulation method of cuvette reagents, using the encapsulation methods of two kinds of reagent as examples, firstly, a separator module with the same cross section with the light pass surface and larger size than the light pass surface is inserted between the two light pass surfaces of the cuvette then the cuvette is divided into two parts, wherein the separator module uses the hard material as the bone core and the hard material is embedded into the flexible polymer; secondly, the two kinds of reagents are respectively injected into the two parts of the cuvette; finally an elastic sealing cover encloses the cuvette. While in use, it is only necessary to rotate the hard bone core of the separator module and then the hard bone core is taken out. The encapsulation method has features of low production cost, simple operation, no reagent injection during analyzing, no cross-contamination due to the selection of disposable plastic cuvette, greatly increased analyze accuracy and efficiency, and is suitable for the manual, semi-automatic, full-automatic clinical biochemical analyzer and other analytical instruments in need of various reagents.

Description

technical field [0001] The invention relates to the technical field of biochemical analyzers, in particular to a method for packaging multiple reagents in a cuvette. Background technique [0002] At present, the biochemical analyzers that can be used for on-site and field testing mainly include dry automatic biochemical analyzers, semi-automatic biochemical analyzers and miniature biochemical analyzers. Among them, the dry-type biochemical automatic analyzer uses dry reagent strips as solid-phase reagents. Although it is simple and quick to use, the production cost of the reagent strips is relatively high; Some steps such as inhalation colorimetry and result recording) need to be completed manually, while the other part of the operation can be completed automatically by the instrument; the micro biochemical analyzer is small in size, light in weight, and easy to carry, but most of the analysis process needs to be completed manually. Semi-automatic and miniature biochemical ...
