Problems solved by technology

However, if the air is not sufficiently pushed out from the container in the above-mentioned order, voids are generated in the container, and thus the above-mentioned problem of concentration of the reagent sometimes occurs.
In addition, the above-mentioned procedure requires the user's proficiency, and there is a concern that the user may come into contact with the reagent and contamination of the reagent when attaching and detaching the cap or extruding air from the bag.

Embodiment 1

[0060] Embodiment 1 reagent supply device

[0061] (manufacturing of laminated body)

[0062] By combining additive-free low-density polyethylene film (thickness 130 μm), polyethylene terephthalic acid film (thickness 12 μm), nylon film (thickness 25 μm), aluminum foil (thickness 15 μm), and polyethylene terephthalic acid film (thickness 12 μm) ) are laminated in this order to obtain a laminated body. It should be noted that the low-density polyethylene film and the polyethylene terephthalic acid film were bonded together with low-density polyethylene during extrusion lamination. In addition, polyterephthalic acid film, nylon film, aluminum foil, and polyterephthalic acid film use linear polymer polyester as a binder, and are bonded by a dry lamination method.

[0063] (reagent container body)

[0064] Using the obtained laminate, a flexible bag was produced so that the above-mentioned additive-free grade low-density polyethylene film was the innermost layer. Next, the mou...

Embodiment 2

[0071] Embodiment 2 sample analysis device

[0072] As other embodiments of the present invention, in Image 6 A schematic diagram of a blood sample analysis device 100 based on a liquid chromatograph is shown in FIG. exist Image 6 Among them, the support member 113 of the reagent supply device 110 and Figure 4 Similarly, it is formed on the main body of the analysis device 100 that performs analysis using the reagent supplied from the reagent supply device 110 , and the case 120 housing the reagent container is placed there. The housing 120 accommodates three reagent containers 111 having flexible container bodies. Each reagent container 111 is filled with a reagent (hemolysis / dilution / cleaning solution: 111a) as a solution for hemolyzing or diluting the blood sample and a cleaning solution for cleaning the flow path of the sample, and two kinds of elution solutions. liquid (111b and 111c). Each reagent container 111 accommodated in the housing 120 is arranged with the...

Abstract

Provided is a reagent supplying method and a device for the same, whereby a reagent in a container can be used up to the fullest extent possible, and the reagent can be supplied to an analysis device without introducing bubbles even when the residual amount of the reagent is small. A reagent supplying device, provided with at least one reagent container having a container body for accommodating a liquid reagent and a reagent supply port provided to the container body, and provided with a support member for supporting each of the at least one reagent container so that the reagent supply port is positioned at the bottom of the container body, the reagent supply port being blocked by a plug having at least one nozzle passage part, and each of the at least one nozzle passage part being configured from a material having a Shore hardness of A5 degree to A90 degree.

Description

technical field [0001] The present invention relates to a method for supplying a reagent to a sample analysis device, an apparatus thereof, and a sample analysis method using the reagent supply method. Background technique [0002] Sample separation and analysis methods including liquid chromatography are commonly used in analysis and inspection in the fields of organic chemistry, biochemistry, and medicine. In the separation and analysis method described above, various reagents are used, such as an eluent for separating a sample, a cleaning solution for cleaning a column, a cleaning solution for a reagent flow path, a diluent for diluting a sample, and a cleaning diluent for both cleaning and dilution. Conventionally, the above-mentioned reagents have been provided in a glass or resin bottle. However, when reagents are filled in glass or resin bottles, if voids are formed in the bottles due to consumption of the reagents, there is a problem that the reagents are concentrat...
