Abstract: There is provided an automated analysis device capable of transferring instruments to be used for an analysis process to a predetermined processing position efficiently and rapidly. In an automated analysis device of the invention, a transfer unit forming a transfer mechanism to transfer instruments to be used for analyte processing into an analyte processing space includes a holding portion to hold the instruments. The holding portion includes a first fitting attachment portion to be attachable to a first instrument in a fitted state, and a second fitting attachment portion to be attachable to a second instrument in a fitted state.

Abstract: There is provided an automated analysis device capable of transferring a reagent for reagent dispensing efficiently and rapidly. An automated analysis device of the invention includes a reagent transfer unit to transfer a reagent suction nozzle between a reaction unit and a reagent supply unit. In a region of an analyte processing space where a tip supply unit, the reagent supply unit, a tip disposal unit, and the reaction unit are lined up along a straight line, the reagent transfer unit forms a uniaxial transfer line where the reagent suction nozzle is moved only in a uniaxial direction along the straight line for a reagent transfer.

Abstract: There is provided an automated analysis device capable of transferring a rack to a predetermined instrument extraction position efficiently and rapidly, the rack being loaded with instruments to be used for an analysis process. An automated analysis device of the invention includes a conveyance unit to raise and lower a plurality of racks in a vertically stacked state to convey the racks into an analyte processing space, the racks being loaded with instruments to be used for analyte processing. The conveyance unit includes a movement mechanism to move an uppermost rack from a rack standby position to an extraction position with guidance of a protrusion and a recess while maintaining a state of slidable protrusion and recess engagement between the uppermost rack and a rack below the uppermost rack.

Abstract: A clinical examination disk according to the invention includes a disk body in a disk form, and at least one cell formed in the disk body, wherein the cell comprises a specimen reservoir formed in the disk body and having a specimen injecting port, a reaction tank formed in the disk body so as to position nearer to the outer circumference of the body than a position of the specimen reservoir, and holding a reagent which is reactive with the specimen and is beforehand gelatinized, a first narrow tube formed in the disk body, and communicating to the specimen reservoir and the reaction tank, and a second narrow tube formed in the disk body, and having one end connected to the reaction tank and the other end made open.

Abstract: An automatic immunoassay method and apparatus which not only permit automatic operations of supplying and discarding reaction tubes, washing for B/F separation, dispensation of reagents, and measurement, but also permit the reaction time to be varied arbitrarily and can cope with any of the assay techniques including one-step and two-step noncompetitive sandwich techniques and competitive techniques.
