A plurality of analyzer units for serum, a plurality of analyzer units for blood plasma and a plurality of analyzer units for urine are arranged along a main transfer line for transferring a sample rack from a rack providing portion to a rack storage portion. A reagent bottle for inspecting liver function is contained in each reagent delivery mechanism of two analyzer units among the plurality of analyzer units for serum. When the reagent for inspecting liver function in one of the two analyzer units is to be short, analysis for the liver function analysis item to samples can be continued by transferring a sample rack from the rack providing portion to the other analyzer unit.

Analyzer system having sample rack transfer line

It is an object of the present invention to provide a small-sized automatic analyzer that is convenient in use, wherein an insertion of an urgent sample can be easily carried out, its safety in operation and operability can be improved and its erroneous operation can be prevented. In order to accomplish the object of the present invention, a top panel of a body is provided with a sample disk storing a plurality of sample cups, a reagent disk storing a plurality of reagent bottles, and a reaction disk storing a plurality of reaction cuvettes for reacting sample liquid in sample cups with the reagent in reagent bottles and there is arranged an indicator illuminated when the sample disk is stopped, and there is provided a cover for covering a part of the top panel of the body, and when the cover is closed, a part of the sample disk is exposed out of the cover. The sample disk is provided with sample disk covers constituted in two-divided segments, and one of the covers is arranged at a position where it is removably exposed outside the cover when the cover is closed.

Automatic analyzer

A plurality of analyzer units for serum, a plurality of analyzer units for blood plasma and a plurality of analyzer units are arranged along a main transfer line for transferring a sample rack from a rack delivery portion to a rack returning portion. A reagent bottle for inspecting liver function is contained in each of reagent delivery mechanisms of two analyzer units among the plurality of analyzer units for serum. When reagent for inspecting liver function in one of the two analyzer units is to be short, analysis for liver function analysis item to samples can be continued by transferring a sample rack from the rack delivery portion to the other analyzer unit.

A sample of a sample rack is sampled at analyzing units in the middle of a transfer line. A standby unit and a rack collecting unit are arranged near an exit of the transfer line. After sampling, sample racks are sorted out to the standby unit or the rack collecting unit at a first switching unit. The racks contained in the standby unit are sorted out to a returning line or the rack collecting unit in a second switching unit corresponding to a judged result of whether or not reexamination is required.

Automatic analyzing apparatus

A sample analysis system includes blood serum analysis units, blood plasma analysis units and urine analysis units which are arranged along a main conveyor line. The width size of each analysis unit on the side along the main conveyor line is the same. Each analysis unit can be removed integral with a sampling line and its rack transfer device from, the main conveyor line. Removed analysis units can be replaced by each other without changing the entry and exit positions for the sample rack. The conveyor line has the same number of line frame segments as the number of the analysis units.

Reagent bottle

Reagent bottle holder for a reagent disc

A reagent containing device has an outer bottle holder and an inner bottle holder. The holders are rotated independently of each other. When an instruction for exchanging reagent bottles inside the reagent containing device is input, a first reagent bottle on the outer bottle holder and a second reagent bottle on the inner bottle holder relating to the same analysis item are positioned at an opening of a bottle exchanging area. Then the opening is opened by a sliding operation of a lid so that the first reagent and the second reagent bottles can be unloaded through the opening.

Apparatus for analyzing a plurality of analysis items

An automatic analyzing system has a sample table for supporting a plurality of sample vessels and a reagent table for supporting a plurality of reagent vessels. The sample table and the reagent table are fixed to a common drive shaft. The system further has a rotatable reaction table for supporting a plurality of reaction vessels. The reaction table is arranged in a side-by-side relation to the sample table and the reagent table. The system further has a single pipetting device disposed between the reaction table and the stack of the sample table and the reagent table for a swinging motion therebetween so as to suck samples and reagents from the sample vessels and the reagent vessels and to deliver the same to the reaction vessels. The pipetting device is operated in such a manner as to transfer all the samples to the reaction vessels followed by the supply of the reagents to these reaction vessels.
