  • Patent number: 11624752
    Abstract: 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.

  • Patent number: 11079402
    Abstract: Provided is an automatic analyzer that has a plurality of mechanisms including a mechanism that suctions reaction waste liquid and a mechanism that suctions cleaning liquid, etc. on a sample and a probe surface, the automatic analyzer reducing pressure in a vacuum tank using a pressure-reducing pump, etc., and suctioning waste liquid by negative pressure in the vacuum tank. A contact point of a vacuum switch that is provided in the vacuum tank is closed when the pressure in the vacuum tank reaches a specified negative pressure, and then the analyzer becomes ready for analysis. If any flow path portion of any mechanism that connects with the vacuum tank becomes clogged, suctioning operation cannot be performed properly and analysis performance is affected. The vacuum pump is switched off at a timing at which each solenoid valve connecting to the vacuum pump is individually opened, and the time that elapses before the pressure in the vacuum tank reaches the specified negative pressure is measured.
