Automatic analysis device and sample analysis method

Abstract

The invention provides an automatic analysis device and a sample analysis method. The automatic analysis device comprises an injecting unit (20) used for injecting a sample and / or a reagent into a reaction container, a reaction unit (10) used for hatching, cleaning and separating a reactant in the reaction container, a measurement device (86) used for measuring a reaction signal in the reaction container, and a transfer unit (50) used for transferring the reaction container between different positions. The reaction unit is provided with at least one of hatching transfer positions (13a1-3, 13b1-3, and 13c1-3) and at least one cleaning and separating transfer position (13d1-2), and the transfer unit (50) transfers the reaction container between the hatching transfer positions (13a1-3, 13b1-3, and 13c1-3) and the cleaning and separating transfer position (13d1-2), so that flexible hatching is realized, the problem in the prior art that multiple cleaning and separating mechanisms need to be used to implement the two-step-method test is also solved, and the efficient cleaning and separating is fully realized.

Description

technical field [0001] The invention relates to the field of in vitro diagnostic equipment, in particular to an automatic analysis device and a sample analysis method. Background technique [0002] In recent years, the development and progress of clinical testing and automation technology has not only improved the level of clinical laboratory automation, improved the efficiency of medical testing, but also improved the quality and reliability of test results. However, as the amount of test specimens increases, clinical laboratories need to continuously add large-scale automated testing systems to meet their testing needs, resulting in increasingly crowded laboratories and rising testing costs. Therefore, under the pressure and challenge of medical insurance cost control, how to improve the efficiency of testing, guarantee the results, make full use of existing laboratory resources and reduce testing costs is an urgent problem to be solved in clinical testing.

Problems solved by technology

In order to achieve flexible incubation time, the technical solution requires complex control of the incubation measurement unit, and the control of incubation and measurement will also restrict each other, which not only has the disadvantages of being unable to realize high-speed automated testing, but also cannot achieve flexible signal incubation.

[0011] The third prior art solution realizes incubation, cleaning, separation and measurement on a single-circle disc or divergent track. In order to support longer incubation time, in addition to cleaning, separating and measuring positions, the disk also needs to set a lot of incubation positions, so in order to achieve high-speed testing, the size of the disk or divergent track needs to be designed to be large, which is difficult to manufacture and high in cost. In addition, in order to To realize delayed one-step and two-step testing, at least two sample loading mechanisms and at least two cleaning and separation mechanisms are required, which increases the cost of materials, processing, production and overall machine size

On the other hand, this technical solution also limits the incubation time, leading to problems such as fixed incubation time and too long time to produce results.

In addition, this technical solution is not only difficult to achieve the darkroom environment required for measurement, it needs to add an additional shutter mechanism, and it cannot achieve flexible signal incubation
