Embodiment Construction

[0026] Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. Among them, the present invention is mainly capable of accommodating the dispensing tip that has been in contact with the reagent at least once, and in order to avoid contamination caused by liquid dripping during the movement of the dispensing arm or liquid scattering when the dispensing tip is removed, the dispensing tip is placed on the side of the tube. What is necessary is just to have the structure which has a protrusion above the periphery of an opening part, and it is not limited to the specific example mentioned in the following detailed description.

[0027] First, combine figure 1 , figure 2 The brief structure of the gene testing device of the present invention will be briefly described. The gene detection device of this embodiment is mainly composed of: a multi-purpose arm 1 equipped with a dispensing function and a function of holding a re...

Abstract

In recent years, nucleic acid amplification technology characterized by detection through the amplification of micro-scale target genes is adopted as a method for detecting infectious diseases and genes, however, because a dispensing nozzle has to be replaced while dispensing the reagent and samples, the arrangement space of consumables is increased or the consumables have to be erected frequently to result in the decreasing of automation. The invention provides an automatic analyzing device having higher usability. The automatic analyzing device allows the repeated use of the dispensing nozzle (6), by providing a tube set (8) having a separating plate (10) higher than the front end of the dispensing nozzle when a dispensing structure stops, without the need for considering the dripping of the liquid at the front end of the dispensing nozzle (6) after absorbing the reagent or the dispensing nozzle having left liquid after discharging the reagent and for considering the pollution of the dispensing nozzle (6).

Description

technical field [0001] The present invention relates to an automatic analyzer equipped with a dispensing mechanism for sucking and discharging samples and reagents. Background technique [0002] Nucleic acid amplification technology, which amplifies and detects a small amount of a target gene, is used as a method for detecting infectious diseases and genes. Among them, the well-known PCR (Polymerase chain reaction: polymerase chain reaction) method repeats three steps of denaturation of a double-stranded template DNA to a single strand, annealing of a primer for the single-stranded DNA, and extension of a complementary strand derived from the primer. The method of denaturing and extending the two processes to exponentially amplify the target gene. [0003] In this method, preparation of reagents is cumbersome and requires skill, and it takes several hours to obtain results. Therefore, automation is desired in order to reduce the burden on testers. AmpriPrep (Roche Corporat...
