Abstract

Disclosed is an automatic analyzing system, which is given a function to check whether the actions of individual portions thereof are being correctly executed or not. A pressure sensor is applied to a sample passage so that the action steps of a dispensing mechanism including the opening / closing of an electromagnetic valve can be checked in terms of a pressure waveform during a rinsing water discharge (10). Here, this function can also apply the pressure sensor which is used in a sample suction check of the prior art, as an additional function. Even with the ON / OFF failure of the electromagnetic valve, the discrimination can be made with an alarm so that the sample can be prevented from becoming thin, to thereby improve the data reliability.

Description

technical field

[0001] The present invention relates to an automatic analyzer for qualitative and quantitative analysis of specific components in biological samples such as blood and urine, and more particularly to an automatic analyzer having a dispensing unit for dispensing a predetermined amount of liquid. Background technique

[0002] Clinical examinations that analyze components contained in biological samples such as blood and urine of patients react the samples with reagents to perform qualitative and quantitative analysis of target components in the samples. In this case, a liquid supply mechanism called a dispensing mechanism is used to supply a predetermined amount of the sample and the reagent to the reaction container for reacting the sample and the reagent. As the liquid supply mechanism, use a pressure changing unit such as a syringe or a diaphragm to make the pressure in the nozzle that sucks the liquid a negative pressure, and after the suctioned liquid is su...
