Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a sampling system of an automatic analyzer.

[Conventional technology]

As shown in FIG. 4, the sampling system of the automatic analyzer for analyzing body fluids such as urine and serum is a sampler 3 which supplies a sample.
0 (turntable in the illustrated example) to A, B, C of reaction tubes 9 arranged according to the required number of inspection items, ..., a pipetter 7 for reciprocating to these reaction tubes, and the like. There is. The pipettor 7 has a built-in device for sucking the sample of the sampler 30 and dispensing it to the reaction tubes 9 A, B, ..., And is attached to the drive shaft 8 to reciprocate.

[Problems to be solved by the invention]

The conventional automatic analyzer as described above has a problem that it is not easy to handle a plurality of samples (for example, urine, serum, etc.) because the sampler section is single.

[Purpose of device]

The present invention has been made in view of the above-mentioned problems, and an object thereof is to facilitate arrangement of a plurality of sampler systems to support samples of a plurality of systems, and further to provide a plurality of sampler systems. The purpose is to have a variety of uses as a different structure (such as a turntable system or a rack system).

[Means for solving problems]

That is, in order to solve the above-mentioned problems, the present invention provides an automatic analyzer that incorporates a sample sampler system and an analyzer and samples by a pipettor, while arranging a plurality of sampler sample systems for one pipettor system. ,
It is characterized in that one of the plurality of sample sampler systems is constituted by a belt conveyor for transporting a sample rack and a sample installation / storage unit connected to the belt conveyor.

[Action]

It is possible to inspect a certain sample with one pipettor system and to immediately inspect another sample as soon as it is finished, or to alternately inspect while sampling different types of samples. Further, since the form of the sample supply mechanism can be diversified according to the purpose of the inspection, the inspection for the emergency interruption or the inspection by combining a plurality of samples becomes smoother.

〔Example〕

Specific embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an embodiment view of a sampler system of an automatic analyzer according to the present invention, (1) is a plan view and (2) is a front view. In this figure, reference numeral 1 is a sampler section, which is a turntable in the illustrated example. 2 is also a sampler section, which is also a turntable. Of these sampler units 1 and 2, for example, a test tube P containing a sample of urine is set on the turntable 1, a test tube Q containing a sample of serum is set on the turntable 2, and samples of different systems are set. . The turntables 1 and 2 are rotated by a motor 5 and a motor 6 around a shaft 3 and a shaft 4, respectively.

Reference numeral 7 is a pipettor, and 8 is a shaft for driving the pipetter 7 so as to reciprocate left and right. The driving of the pipette 7 by the shaft 8 may be performed by using a pulse motor (not shown) as a drive source and by screwing a timing belt and a timing pulley or a female screw and a male screw. Reference numeral 9 is a reaction tube for analysis, and the necessary number is arranged according to the inspection item.

The positioning when the pipettor 7 reciprocates between the turntable 1 or 2 and the reaction tube 9 may be performed by controlling the pulse number of the pulse motor.

Reference numeral 10 is a rack for the reaction tube 9, and the rack 10 is adapted to move in the direction of the arrow by a belt line or the like.

Then, first, the pipettor 7 is the turntable 1 and the reaction tube 9.
The sample is sucked and dispensed repeatedly in the test tube P by reciprocating between the two. When the inspection of the turntable 1 is completed, the pipette 7 is turned by the same drive source.
The suction pipette is repeatedly inspected by reciprocating between the reaction tube 9 and the reaction tube 9.

Further, as described above, not only the method of starting the inspection of the sample of the turntable 2 after the completion of the inspection of all the samples of the turntable 1, but also the samples No. 1 and NO.
2, then turntable 2 NO.1 and turntable 1 NO.3, NO.4, NO.
5 and then turntable 2 samples No. 2 and No.
The inspection may be performed in an irregular order such as inspecting 3, ... However, even in such a case, ID (confirm the identity)
Input must be secure.

As described above, the main point of this invention is to provide a plurality of sampler systems for one pipettor system in the biochemical analyzer, but as shown in FIG.
The sample setting yard 12, the sample pretreatment device 13, the analyzer 14, the tested sample storage 15 and the like are connected to form a single sampler system, and in addition to the automatic analyzer having the sampler system of the belt conveyor 11, a turntable is provided. It may be configured to have a sampler system having a completely different form such as 16.
That is, referring to FIG. 2, a test tube containing a sample, for example, a rack (containing untreated blood) 17 containing a blood collection tube R is arranged in the sample setting yard 12 to be in a start state. The rack 17 with a blood collection tube is placed on the belt conveyor 11 and conveyed by a magic hand or a robot mechanism (not shown). Next, the blood in the blood collection tube is separated here by the pretreatment device 13. The separated sample is further sent by the belt conveyor 11 and comes to the front of the analyzer 14. Here, the sample is aspirated and dispensed. Further, the rack 17 moves forward and is stored in the inspected sample storage 15 by a robot mechanism (not shown) or the like. The turntable 16 is used when the belt conveyor 11 is out of order or when it is desired to inspect a sample in a system different from that of the belt conveyor 11.

Further, as shown in FIG. 3, one sampler system is a turntable 20, and the other sampler system is a belt conveyor 21 which runs a rack 22 on which a sample is arranged. You may combine different things. That is, one sampler system is the turntable 20 in which the test tubes containing the samples are arranged, and the other is from the sample setting yard 23 to the belt conveyor 21 by the magic hand or robot mechanism (not shown).
And run. Then, after the sample on the turntable 20 side is sucked and dispensed by the pipettor system 7, the rack 22 is stopped by the stopper 24 and the sample placed on the rack 22 is sucked and dispensed into the reaction tube 9 or these samplers are sampled. The system is alternately sucked and dispensed. The inspected reaction tube 9 is stored in the inspected sample storage 25 by a robot mechanism or the like (not shown).

[Effect of device]

As described in detail above, the present invention is characterized in that a plurality of sample sampler systems are arranged for one pipettor system in an automatic analyzer that incorporates a sampler sampler and an analyzer and samples by a pipettor system. So
It is possible to set specimens of different strains to different samplers and perform different tests at the same time. Further, since the sample installation position and the tested sample storage position are connected by the belt conveyor, it is easy to collect the tested sample.
