According to one embodiment, an automatic analyzer includes dispenser, measurer, thermostat, cooler and cleaner. Dispenser dispenses a specimen and a reagent into a reaction vessel. Measurer measures a solution mixture of the specimen and the reagent in the vessel. Thermostat heats the mixture to a first temperature at which thermoresponsive polymers contained in the reagent aggregate. Cooler cools a cleaning fluid used to clean the vessel to a second temperature lower than the first temperature, at which the polymers contained in the reagent disperse. Cleaner cleans the vessel from which the mixture has been drained, using the cooled fluid.

An automatic analyzer has a supply unit that stores and supplies a liquid to be used by the analyzer, an analyzer circulation system that circulates the liquid within the analyzer, and a supply unit circulation system that circulates the liquid within the supply unit. An analysis controller switches a flow rate of the liquid circulated by at least one of the analyzer circulation system and the supply unit circulation system between a first flow rate in a normal state and a second flow rate different from the first flow rate. Consequently, by suppressing fungal propagation within a circulation flow path for a liquid, compared to conventional techniques, the frequency with which a liquid is replaced and the frequency with which the inside of a reaction tank is cleaned are reduced and a time period for a maintenance operation by an operator is reduced.

An automatic analysis device has a plurality of types of photometers having different quantitative ranges, and an analysis control unit for quantifying the desired component in specimens based on measurement values of one or more photometers selected from among the plurality of types of photometers. The analysis control unit: sets a switching region in an overlap region of respective quantitative ranges of the plurality of types of photometers, said switching region having a greater width than does the variation in quantitative values of the desired component based on the measurement values of photometers having the same specimen; compares the quantitative value of a quantitative range portion that corresponds to the switching region and the quantitative values of the desired component based on the measurement values of the photometers; and selects a photometer to be used in quantitative output of the desired component from among the plurality of types of photometers.

Disclosed herein are high-throughput sample processing systems and waste management systems, and methods of using the same.

The present invention relates to a heat preservation shell (4) for an analyzer. At least one liquid passage (402) for conveying the liquid is embedded in a shell wall of the heat preservation shell. The liquid passage (402) is embedded in the shell wall of the heat preservation shell (4), on one hand, the liquid transported or preserved in the liquid passage is subjected to the heat preservation function of the heat preservation shell, so that the liquid transported or preserved in the liquid passage (402) maintains the preset temperature, thereby avoiding the influence of the external environment temperature on the transported liquid; and on the other hand, the space of the shell wall of the heat preservation shell is effectively utilized, the situation that various liquid pipelines are intricately distributed inside or outside the heat preservation shell (4) is avoided, thereby increasing the space utilization rate.

A reaction analysis system includes a first flow path through which a reaction fluid, obtained by mixing reactants in a mixer, flows, a second flow path through which the reaction fluid flows and that has higher heat exchange efficiency than the first flow path, a temperature measurer that measures a temperature distribution of the reaction fluid along the first flow path, and a reaction analysis device that specifies a reaction state of the reaction fluid based on a reaction parameter. The reaction parameter is obtained from the measured temperature distribution and indicates the reaction state of the reaction fluid.

Provided is an automatic analysis device capable of adjusting the temperature of a plurality of portions requiring temperature control with less power consumption as a whole.

An automatic analysis device includes; an air-conditioned space 20 which is partitioned from the surroundings and in which a reagent is used; a Peltier unit 1 which includes a Peltier element 101 for adjusting an air temperature of the air-conditioned space 20; a heat sink 111 that cools or heats the Peltier unit 1 with a refrigerant; a first radiator 12 which performs heat exchange between the refrigerant which has exchanged heat with the heat sink 111 and the air in the atmosphere; pumps 10 and 11 that circulate the refrigerant; a reagent storage unit 30 which cools and stores the reagent; Peltier units 2, 3, and 4 which include Peltier elements 102, 103, and 104 which adjust a temperature of the reagent storage unit 30; heat sinks 112, 113, and 114 that cools or heats the Peltier elements 102, 103, and 104; and a second radiator 13 which dissipates the heat of the refrigerant that has exchanged heat with the heat sinks 112, 113, and 114.
