DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to an automatic analyzer operating automatically for biochemical analysis and immunological analysis.
BACKGROUND OF THE INVENTION
Various kinds of automatic analyzers have been proposed. However, many of the recent automatic analyzers are rather complicated, large-sized, high-cost and high-speed operating, and moreover, involve an exceedingly complicated operation, and therefore a specialized operator must be attendant thereon all the time, and personnel expenses are a problem.
This kind of large-sized automatic analyzer is not always required by local hospitals and clinics where a large amount of blood examination is not necessary, and in such circumstances a specialized examination center is requested to carry out blood examination of respective patients.
Consequently, where an urgent examination is required, an inconvenience may result in such local hospitals and clinics, a waste of money is quite unavoidable, and moreover, in case work for comparing an analysis with the patient's blood or reexamination is required, a long time will be needed for obtaining a result.
This invention has been made in view of the situation described above, and its object is to provide a simple automatic analyzer, miniaturized to cope with a need by local hospitals and clinics, which is very simple in operation and construction, and moderate in cost.
DISCLOSURE OF THE INVENTION
In order to attain the aforementioned object, the automatic analyzer relating to the invention comprises a means for moving a plurality of samples to a sample sucking position, a means for sucking a predetermined quantity of sample at the sample sucking position and pouring the predetermined quantity into a reaction cell, a means for moving the reaction cell to an optical measuring position, a means for pouring a reagent corresponding to a charactristic to be measured into the reaction cell, a means for moving a reagent container in which the reagent corresponding to a characteristic to be measured is contained to a reagent sucking position, a means for measuring a sample in the reaction cell optically, a means for washing the reaction cell after completion of the measurement, an IC card storing various starting command signals and measurement data, a reader/writer for reading command signals of the IC card and writing the measurement data.
In the invention, the IC card comprises a starting IC card in which command signals for actuating and controlling a sample moving means, a sampling means, a reaction cell moving means, a reagent pouring means, an optical measuring means and washing means are inputted, and a memory IC card storing data measured by the optical measuring means. Needless to say, a single IC card may be so constructed as to work for both starting and memory at the same time.
In the invention, a thermostat is provided having a plurality of heating members at predetermined intervals on the bottom of a thermostatic oven constituted by a heating medium, and the temperature in the thermostatic oven is made uniform by controlling the heating members separately by a temperature controller.
Further, in the invention, a table holding the reaction cells thereon turn in steps the number of which is one less than the number of the reaction cells held on the table so that the reaction cells will be moved relative to a fixed point one by one intermittently counter to the direction in which the table turns.
