Embodiment Construction

[0206] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the sample in the present invention refers to particulate objects, such as organic substances such as cells, inorganic substances such as polystyrene, foaming substances, magnetic substances, etc., metals and other substances with a size of about 0.1 μm to 500 μm. , or, to indicate their state of being suspended in a liquid. Also, the sample indicates a substance marked with the presence or absence or degree of its identification element, or a substance that emits light naturally. In this case, the sample may be marked by the presence or absence or combination of a plurality of identification elements, or a plurality of samples having multiple identification elements may exist. In addition, the agglomerated sample refers to a substance with a size of about 0.2 μm to 10 mm in which the sample is aggregated, or a state in which they are suspended in a liquid. ...

Abstract

A separation unit can confirms a separation state, a detection unit enhances a lighting efficiency and a light reception sensitivity, and a dispensing unit ensures the normal state of a specimen. A specimen separation device characterized by comprising a container for storing a specimen, a nozzle for sucking and ejecting the specimen from the container, a nozzle operating means for moving the nozzle vertically and laterally, and a nozzle controlling means for controlling the suction force and ejection force of the nozzle. A specimen identification device comprising a nozzle for sucking a specimen from a container storing the specimen, a flow path for allowing the specimen to flow therethrough, and a measuring unit having a monitoring light lighting unit and a light receiving unit for observing (monitoring) the specimen that are installed in a flow path, characterized in that the above nozzle, the flow path and the measuring unit are formed in an integrated structure.

Description

technical field [0001] The present invention relates to a separation method, an identification method, a dispensing method of a sample (agglutination sample), a device for implementing each method, and an analysis device. Background technique [0002] A conventional cell sorter for separating, identifying, and dispensing a specimen is roughly composed of a separation unit, a detection unit, and a dispensation unit. [0003] First, the separating unit will be described with reference to FIG. 41 . First, in order to homogenize the aggregated sample 243 in the test tube 241 , the test tube 241 is vibrated or the inside of the test tube 241 is stirred. Next, suction and discharge 251 of the agglutinated sample 243 in the test tube 241 are repeated with the pipette 245 . The aggregated sample 247 is separated into single samples 249 due to shear stress due to repeated suction and discharge 251 . In this method, the single sample located on the surface side of the aggregated sa...
