The objective of the present disclosure is to provide a technique for reducing a quantity of magnetic particles remaining on a reaction vessel wall surface in a cleaning step for reducing, in a stepwise manner, an amount of a magnetic particle solution in the reaction vessel. The automated analysis device according to the present disclosure causes an agitating mechanism to operate in such a way that a magnetic substance remaining on the wall surface of the vessel in the previous cleaning step is captured by a cleaning solution in the next cleaning step.

Automated analysis device

When the automatic analyzer is installed in an environment with a high altitude and different external atmospheric pressures, there is a problem that an amount of vacuum suction decreases due to a decrease in suction performance of a vacuum pump and it is difficult to perform vacuum suction of an analyzed reaction liquid. In view of the above, by newly providing a pressure adjustment mechanism within a flow path connecting a vacuum tank to vacuum pump, it possible to control the pressure difference between a pressure in the vacuum tank and an external atmospheric pressure where the analyzer is installed to be constant regardless of the installation environment. Additionally, by providing a hole in communication with the outside in the vacuum tank or a vacuum bin, it possible to control the pressure difference between the pressure in the vacuum tank and the external atmospheric pressure where the analyzer is installed to be constant regardless of the installation environment.

Automatic analyzer

A device for unstopping a stopped specimen vessel that contains a liquid specimen such as blood is equipped with a mechanism which sucks and captures particles floating around the opening of the specimen vessel and prevents contamination of the specimen. The unstopping device grips a vessel and the stopper of the opening of the vessel, and removes the stopper from the opening of the vessel by changing the relative distance between the vessel-gripping mechanism and the unstopping mechanism. The unstopping device is equipped with: suction holes for sucking therethrough the gas which is present around the opening and contains liquid or solid particles; a pipeline which is connected to the suction holes and through which the sucked gas and particles are led downstream; a suction device connected to the pipeline; and a spirally flexed pipeline part disposed between the pipeline and the suction device.
