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: a filling unit (20), which injects samples and / or reagents into the reaction container; a reaction unit (10), which incubates and cleans and separates the reactants in the reaction container; a measuring device (86), which measures the reaction container Reaction signal in; transfer unit (50), transfer reaction vessel between different positions. At least one incubation transfer position (13a) is set on the reaction unit of the present invention 1‑3 、13b 1‑3 、13c 1‑3 ) and at least one wash-separated transfer site (13d 1‑2 ), the transfer unit (50) can be transferred during incubation (13a 1‑3 、13b 1‑3 、13c 1‑3 ) and cleaning separation position (13d 1‑2 ) between transfer reaction containers, not only can achieve flexible incubation, but also can solve the problem in the prior art that multiple cleaning and separation mechanisms must be used to realize the two-step test, and fully realize efficient cleaning and separation.

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
