Automatic reagent strip positioning and leveling device

Abstract

The invention discloses an automatic reagent strip positioning and leveling device which comprises a support, a translation mechanism, a positioning mechanism and a leveling mechanism. The incubation mechanism is arranged on the mobile platform and is provided with an incubation table fixedly connected with the mobile platform, and a reagent strip placing position is arranged on the top surface of the incubation table; the reagent shelf is used for fixing a reagent strip, and the reagent shelf is provided with a pressing plate positioned above the reagent strip; and the locking mechanism is arranged on the moving platform and is used for enabling the pressing plate to move towards the incubation table so as to position and level the reagent strip. The device is simple in structure and compact in layout, after a reagent shelf filled with reagent strips is placed in an incubation disc, along with advancing of the incubation disc, clamping of the reagent shelf and leveling of the reagent strips can be automatically achieved, complex signal judgment and logic time sequence control are not needed, safety and reliability are achieved, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of reagent strip detection, in particular to an automatic positioning and leveling device for reagent strips. Background technique [0002] Chemiluminescence analyzers have the characteristics of high sensitivity, high degree of automation, and fast processing of batch samples. POCT has the characteristics of miniaturization of experimental instruments, simple operation, and instant report results. Applying chemiluminescence immunoassay technology to POCT products can Combining the advantages of both chemiluminescence analysis and POCT, real-time detection can be realized at the patient's side, and diagnostic results can be obtained quickly. With the popularization and application of single-serve reagent strips, the luminescent POCT technology that can complete the detection function with reagent strips has been rapidly promoted. However, in practice, it has been found that since the existing reagent rack s...

Problems solved by technology

However, in practice, it has been found that since the existing reagent rack structure does not have a fixed clamping function, when the reagent rack carrying the reagent strips is placed in the instrument, it will sway left and right or up and down during the operation, which will cause the light metering hole during detection. Deviation from the light metering head and the exposure or light metering value is higher than the actual value, which affects the accuracy of liquid extraction; secondly, the reagent rack cannot level the reagent strips, and the deformed reagent strips cannot be fully positioned with the base, resulting in poor incubation effect , while seriously affecting the stability of magnetic suction and pumping
