The object of the invention is to avoid a decrease in dispensing accuracy of a sample, a reagent, or the like as a temperature changes. In an automatic analyzer, a dispensing nozzle sucks the sample from a sample container holding the sample and discharges the sample to a reaction container. A syringe pump controls an amount of change in a volume of water. A first pipe connects the dispensing nozzle and the syringe pump. An electromagnetic valve flows or stops the water. A second pipe connects the electromagnetic valve and the syringe pump. A branch pipe branches the water. A third pipe connects the electromagnetic valve and the branch pipe. A case accommodates at least the syringe pump, the first pipe, the electromagnetic valve, the second pipe, the branch pipe, and the third pipe. Further, the third pipe includes a heat exchange unit that performs heat exchange of the water.

Provided are a program and personal information protection method which are executed by a system which is operated by a medical practitioner, said program and method comprising: a display process of causing a monitor partto display an examination result screenincluding personal information which identifies a subject; an identification process of identifying the personal information in the examination result screenwhich is displayed in the display process; and an invalidation process of invalidating the personal information identified in the identification process in a captured image which includes the examination result screen. Instances of personal information being displayed in error to outside users are thus reduced in comparison to the prior art, and sharing of examination result information is implemented smoothly.

An object of the present invention is to provide a test method capable of efficiently performing a step of evaluating a surface state of a dispensing probe provided in a dispensing apparatus. In the test method according to the present invention, a first solution in which a coloring matter is dissolved is dispensed to a first container in advance by a first dispensing probe, a second solution in which a coloring matter is not dissolved is dispensed to a second container in advance by the first dispensing probe and then the first solution and the second solution are respectively sucked and discharged by a second dispensing probe. After that, a surface state of the second dispensing probe is evaluated by acquiring an amount of the coloring matter collected by the second solution (see).

Test method and dispensing device

The present invention provides a method of producing a composition containing docosahexaenoic acid as a constituent fatty acid of glycerides. The method includes hydrolyzing a feedstock oil containing glycerides, the glycerides including docosahexaenoic acid as a constituent fatty acid, by action of a first lipase and a second lipase, to increase the proportion of docosahexaenoic acid in glyceride fractions. The first lipase is at least one lipase selected from the group consisting of a lipase obtained from a microorganism of the genus, a lipase obtained from a microorganism of the genus, a lipase obtained from a microorganism of the genus, and a lipase obtained from a microorganism of the genus. The second lipase is a partial glyceride lipase.

Since a detergent is a consumption article, it is desirable that a use amount of the detergent be as small as possible in a limit that the washing effect is not substantially reduced. Provided is an automatic analyzer which includes a syringe pump which is connected to a probe and performs the body aspiration and discharge, a feed pump which feeds washing water for washing the inside of the probe to the probe via the syringe pump and a controller which controls the dispensing mechanism and the syringe pump, in which the controller, in a case of washing the probe by sucking a detergent in the probe a plurality of times, controls the syringe pump so as to discharge the detergent after sucking the detergent and to suck the next detergent without feeding the washing water to the probe by the feed pump.

The purpose of the present invention is to provide an automatic analysis device capable of determining, through a simple processing, whether or not idle aspirate has occurred. The automatic analysis device according to the present invention determines whether or not idle aspirate has occurred, by calculating a parameter which specifies whether or not the length of a portion of a path through which the sample passes inside a dispensing probe is shorter than that during normal aspirate, the portion being actually filled with a sample (see FIG.).

Automatic analysis device

An automatic analyzer is equipped with a sterilization mechanism removably attached to an opening of a container that holds a reagent and having an ultraviolet light generation section that radiates ultraviolet light; a suction nozzle removably attached, together with the sterilization mechanism, to the opening of the container; an analysis section adding the reagent drawn in by suction from the container via the suction nozzle to the reagent, and executing an analysis operation; and a control section exercising variable control over an irradiation light intensity of the ultraviolet light generated by the ultraviolet light generation section.

An automatic analyzer which is capable of detecting a dispensing abnormality with a high degree of accuracy without causing the decrease in the determination performance or the increase in the calculation amount caused by the configuration balance of the reference database is implemented. A dispensing nozzle of a sample dispensing mechanismis immersed in a dispensing target contained in a specimen containerand sucks the dispensing target, and internal pressure of the dispensing nozzle of the sample dispensing mechanismof ejecting the sucked dispensing target to a reaction containeris detected through a pressure sensor. A plurality of feature quantities are extracted from a waveform of the detected pressure, and a determination result is output through a linear combination formula using an optimal coefficient for a determination function that receives a plurality of feature quantities and outputs one value. The determination result indicates whether or not dispensing of the sample dispensing mechanismis performed normally in accordance with the magnitude of the output result of the determination function.
