A container for a reactive product including a container body having a neck delimiting a neck opening; a closure member comprising a puncturable closure membrane which tightly seals off the neck opening; a suction tube located in the container body and comprising a first end portion attached to the closure member and a second end portion extending in the proximity of the bottom of the container body; and a cap attached to the neck and comprising a passage opening which is located facing the puncturable closure membrane and the first end portion of the suction tube, the cap being configured so as to enable the penetration of a sampling needle through the passage opening and the puncturable closure membrane such that the sampling needle is fluidly connected to the suction tube, and so as to enable the penetration of a venting needle through the passage opening and the puncturable closure membrane such that the venting needle is fluidly connected to an internal volume of the container body.

Provided is a reagent cooler that prevents occurrence of condensation and further uniforms a temperature in the cooler with low power consumption and a simple structure. The reagent cooler includes a refrigerant pipe that is disposed inside an outer wall of the reagent cooler 103 and circulates a refrigerant inside the outer wall; a blowing pipe 109 that is disposed inside the outer wall and guides outside air existing outside the reagent cooler to inside of the reagent cooler; and a blowing unit 114 that is disposed at the blowing pipe and diffuses the outside air into the inside of the reagent cooler through the blowing pipe. With the outside air cooled by the outer wall and taken into the inside of the reagent cooler, the reagent cooler is positively pressurized and the internal temperature is made uniform.

The present invention reduces the turnaround time of an automated analyzer. During a period when cyclic measurement by a measurement unit is unnecessary, a controller washes a reaction vessel using a washing cycle having a cycle time shorter than that of an analysis cycle. A single analysis cycle and a single washing cycle both include a reaction disc stopping period and rotation period. In the washing cycle, there is no time during the stopping period when a sample dispensing mechanism, reagent dispensing mechanism, or stirring mechanism operates but there is a time when a washing mechanism operates. The washing cycle stopping period is shorter than the analysis cycle stopping period. The amount of rotation of the reaction disk in the analysis cycle rotation period is the same as the amount of rotation of the reaction disk in the washing cycle rotation period.

Disclosed are a sample analysis apparatus and a sample analysis method. The method includes: obtaining a leukocyte measurement mode for a test sample, the method having a plurality of leukocyte measurement modes, each of which includes at least a reaction time, and different leukocyte measurement modes having different reaction times; determining a reaction time for the current sample to be tested; controlling the sample to be tested to react with the reagent, to prepare a test sample for detecting leukocytes; and controlling to detect the test sample for detecting leukocytes, to obtain detection data of leukocyte classification.

According to one embodiment, an automatic analyzing apparatus includes a feeder and a mixer unit. The feeder is configured to feed a first liquid and a second liquid. The mixer unit includes an inflow part, an internal space, and an outflow part. The mixer unit is configured so that the first liquid and the second liquid fed from the feeder enter through the inflow part, the first liquid and the second liquid entering through the inflow part flow inside the internal space, and the first liquid and the second liquid flowing inside the internal space exit through the outflow part according to an inflow entering through the inflow part.

There is provided an automatic analysis device that can easily realize introduction and replacement of additional reagents in operation even in a small-scale configuration. The automatic analysis device includes a reagent dispensing mechanism 107 that dispenses a reagent from a reagent container 113 containing a reagent, and a normal reagent storage portion 130 that stores a reagent container and an additional reagent storage portion 111. The normal reagent storage portion 130 is positioned in a normal movable area 132, which is a portion of a movable area 131 of the reagent dispensing mechanism 107 and the additional reagent storage portion 111 is positioned in an area excluding the normal movable area 132 in the movable area 131 of the reagent dispensing mechanism 107. The reagent dispensing mechanism 107 performs an access operation in the normal movable area 132 in the normal operation and performs an access operation to the additional reagent storage portion 111 upon receiving a predetermined instruction.

To provide an automatic analyzer capable of relaxing the effect of a previously created mixed liquid when a new mixed liquid is created. An automatic analyzer according to the present disclosure: is configured so as to create a second mixed liquid after a first mixed liquid is created; and introduces a relaxation reagent to relax the effect of a first reagent remaining in a mixed liquid chamber when the second mixed liquid is created into the mixed liquid chamber on the basis of characteristics of the first mixed liquid.

Provided is an automatic analysis device capable of replenishing consumables without loss of a specimen and without stopping analysis. The state of an automatic analysis device 100 includes a replenishment prohibition state in which replenishment of consumables (reaction vessel 8, specimen dispensing tip 10a and external reagent vessels 21a, 21b, 21c) is prohibited, and a replenishment permission state in which replenishment of consumables is permitted. In the replenishment prohibition state, a specimen dispensing mechanism 10 performs dispensing, and detection units 18a and 18b perform analysis. In the replenishment permission state, the specimen dispensing mechanism 10 does not perform dispensing, and the detection units 18a and 18b perform analysis. A device state control unit 119d causes the automatic analysis device 100 to transition to the replenishment permission state when the remaining amount or the remaining number of the consumables predicted by a consumables remaining amount prediction unit 119b becomes equal to or less than a predetermined value.

Provided is an automatic analysis device that estimates causes of change in measurement values of a quality-control substance. An automatic analysis device that analyzes specimens includes an acquisition unit that acquires amount of change in measurement values of a quality-control substance used for quality control, a calculation unit that calculates a change prediction amount on the basis of a difference value in concentration values of a standard solution used for calibration before and after changing lots, and an estimation unit that estimates causes of change occurring in measurement values of the quality-control substance on the basis of results of comparing the amount of change and the change prediction amount.

The present invention provides a nucleic acid analysis device that, even when a plurality of flow cells is handled, does not require an increase in the required movement amount, and can be reduced in size by reducing the size of a stage mechanism. This nucleic acid analysis device is characterized by having a sample container containing a nucleic acid sample to be analyzed, an imaging means for observing the nucleic acid sample, and a stage mechanism for moving the sample container, and is characterized in that the stage mechanism has two translation means and at least one rotation means, one of the two translation means is disposed on the upper surface of the rotation means, and the other is disposed on the lower surface of the rotation means.
