To provide a reagent cooler reduced in size as compared with that in the related art by reducing a thickness of a heat insulation material of the reagent cooler, and an automated analyzer including the reagent cooler. In the reagent cooler of the automated analyzer, a vacuum heat insulation material is disposed in a periphery (on a side surface, or/and upper and lower portions) of a cooling jacket of the reagent cooler. Then, an end portion of the vacuum heat insulation material is disposed at a position shifted from upper and lower end portions and a side surface end portion of the cooling jacket and a distance between the end portion of the vacuum heat insulation material and the cooling jacket is taken as much as possible.

Automated analyzer

Provided is an automatic analysis device that can suppress the occurrence of condensation in a reagent cool box and can immediately drain the condensation water generated by introducing outside air. In an automatic analysis device including a reagent cool box that stores a plurality of reagent vessels while keeping the reagent vessels cool, the reagent cool box includes a drain for discharging the condensation water generated inside the reagent cool box, and an outside air introduction path that guides air outside the reagent cool box to the inside, wherein the outside air introduction path is provided along a bottom surface of the reagent cool box, and an outside air discharge port is formed toward an upper opening unit of the drain.

Automatic analysis device

Provided is an automatic analyzer to control a temperature of a reagent supplied to a magnetic separator with high accuracy. The automatic analyzer includes a magnetic separator that separates a magnetic component and a non-magnetic component from liquid obtained by reacting a sample with a first reagent, a storage unit that accommodates a second reagent, a pipe used to supply the second reagent to the magnetic separator, and a heat exchanger that adjusts a temperature around the pipe. It is preferable that the heat exchanger includes a heat absorption and dissipation unit and a fan that blows air heat-exchanged by the heat absorption and dissipation unit, and the air blown from the fan is blown onto the pipe.

Automatic analyzer

The invention provides an automatic analyzer capable of closing a lid of a container containing a reagent or a specimen without wearing an upper surface of the lid even when the lid fails to close. The automatic analyzer includes a container accommodation portion that has a lid openable and closable by a rotation fulcrum and accommodates a container containing a reagent or a specimen, and a lid closing guide portion that closes the lid by moving relative to the container accommodation portion, wherein the lid closing guide portion is in contact with an edge of the lid to close the lid.

An automatic analysis device includes a processing unitwhich performs the treatment on a specimen before analysis of the specimen, supply equipment which supplies a reagent to a reaction vesseldisposed in the processing unit, a liquid temperature adjusting unitwhich adjusts a temperature of the reagent supplied to the reaction vesselby the supply equipment, a control unit, and a first temperature detection unitwhich detects at least one temperature of a temperature of the air within the processing unitand a temperature of the reagent supplied to the reaction vessel, in which the liquid temperature adjusting unitand the control unitexecute temperature adjustment of the reagent based on a first temperature detected by the first temperature detection unit

Provided is an automated analyzer comprising a temperature regulator that can be made more compact in size while maintaining high-precision temperature regulation. In a temperature-regulating unit () of the automated analyzer, a first chemical reservoir () is constituted by a large-diameter spiral-shaped pipe, and a second chemical reservoir () is constituted by a large-diameter chemical reservoir container. The first chemical reservoir (), which is positioned upstream of the second chemical reservoir (), has an internal capacity that is set so as to be greater than the volume of a single discharge of each of syringe pumps (), and the second chemical reservoir () also has an internal capacity (volume) that is set so as to be greater than the volume of a single discharge of each of the respective syringe pumps ().

Temperature uniformity of a reaction liquid in a plurality of reaction containers of an automatic analysis device is maintained by a heat block. A strip-shaped heater heats the heat block, and is wound and attached on an outer circumference of the heat block so that both end regions of the strip-shaped heater are adjacent to each other. The strip-shaped heater includes a heat generating resistor that is heated by applying an electric current, an insulating film sandwiching the heat generating resistor, and first and second electrical feed lines that are attached to both end portions of the heat generating resistor and supply power to the heat generating resistor. The width of the heat generating resistor in both end regions of the strip-shaped heater is formed to be narrower than the width of the heat generating resistor in the other region thereof.
