Full-automatic chemiluminescence immunoassay device

Abstract

The invention discloses a full-automatic chemiluminescence immunoassay device which is characterized in that a rack is provided with a sample and suction head storage module, a reagent reaction module, a sample adding and transporting module, a lighting module and a reagent cleaning and separating module, and the sample and suction head storage module is arranged below the reagent reaction module; the reagent reaction module is arranged below the sample adding and transporting module, the lighting module and the reagent cleaning and separating module, and the reagent cleaning and separating module is arranged between the sample adding and transporting module and the lighting module. According to the invention, the suction head, the magnetic bar sleeve and the membrane breaking head are automatically added and removed; automatic sample adding and layout are realized; a conductive suction head is matched with a liquid level detection system, the depth of the suction head inserted below the sample liquid level is accurately controlled, and the sample adding precision requirement of the whole device is guaranteed; the reagent strip is sealed and packaged, so that the expiration date of the reagent is long, and the reagent is convenient to transport; the state of the suction head is monitored in real time, the abnormal state of the suction head is fed back in time, corresponding correction is carried out when necessary, and the whole device is more intelligent.

Description

technical field [0001] The invention belongs to the technical field of biological detection, and in particular relates to a fully automatic chemiluminescent immunoassay device. Background technique [0002] The chemiluminescence immunoassay technology, which emerged in the 1970s, has developed into a mature and advanced ultra-trace active substance detection technology with a wide range of applications. The detection technology has the advantages of high sensitivity, strong specificity, low price of reagents, stable reagents and long validity period (6-18 months), stable and fast method, wide detection range, simple operation and high degree of automation. At present, large-scale chemiluminescence immunoassay instruments packaged with multiple reagents are common in the market. This kind of machine occupies a large space and requires high sample volume. The reagents must be used within the specified time after opening, otherwise the test results would be inaccurate.

Problems solved by technology

At present, large-scale chemiluminescence immunoassay instruments packaged with multiple reagents are common in the market. This kind of machine occupies a large space and requires high sample volume. The reagents must be used within the specified time after opening, otherwise the test results will not be accurate

This type of instrument is not suitable for hospitals with a small sample size or township hospitals

At the same time, the operation of such large-scale instruments is complicated, and operators need to undergo systematic training before they can operate the instruments, which is not conducive to the promotion of small and medium-sized hospitals with limited medical resources.

Moreover, the cost of such large-scale instruments is very high, which cannot be afforded by township hospitals, which is not conducive to the vigorous promotion of primary medical care.

At present, there are few single-serve reagent strip chemiluminescence immunoassay analyzers on the market. This type of instrument needs to manually complete the sample addition process. There are cumbersome operations and inconsistent test results due to different operators, which is not conducive to mass promotion.
