本考案は、臨床血液分析装置などの自動分析装

に撹拌・吸引する装置に関するものである。[Detailed Description of the Invention] Industrial Application Field The present invention relates to an apparatus for effectively stirring and suctioning a sample, particularly a highly viscous sample, in an automatic analyzer such as a clinical blood analyzer.

などの結果を生ずるおそれがあつた。Conventional technology Conventionally, in blood analyzers and the like that analyze highly viscous samples such as blood, in order to obtain a more homogeneous sample through stirring or to avoid cross-contamination between samples caused by the stirring device, manual labor was used. Therefore, there is a method of stirring the sample containers one by one and having the analyzer aspirate the sample, or shaking the sample container itself in advance.
The method used was to manually aspirate the sample from each sample container into the analyzer. For this reason, despite the automation of sample dilution, reagent addition, and analytical measurements, the sample supply stage still requires manual labor, and this can lead to insufficient mixing and sample mix-ups. It was becoming. Especially in hospitals and testing centers that handle large quantities of samples, there are many relatively automated devices,
This method had the disadvantage of requiring a dedicated inspection worker to supply the sample. In addition, insufficient agitation due to test worker fatigue, or mix-up of samples could have a serious impact on test results, potentially resulting in misdiagnosis or treatment errors.

いる。 Conventionally, as shown in Japanese Patent Application Laid-Open No. 52-28390, it consists of an intermittent moving means for a container row, a liquid pourer, a stirring device, and a measuring means, and includes pouring pipes 3 and 8 and a stirring device 7. An automatic analyzer is disclosed in which the extraction tubes 3 and 8 are precessed by combining the above.

A sampling mechanism for an automatic analyzer is disclosed in which the volume and spring force are balanced so that the nozzle is immersed in the liquid by a constant height.

難しい。Problems to be Solved by the Invention However, the structure described in the above-mentioned Japanese Patent Application Laid-open No. 52-28390 supports the middle of the tube 11 at the fulcrum 10 and causes the tube to precess. It is difficult to shorten the tube 11 because it requires a length of .

問題点がある。 In the case of the structure described in JP-A No. 52-28390, there is no problem no matter how long the tube 11 is, but when the sample stirring/suction pipe 6 serves as both a stirring rod and a suction tube as in the present invention, However, there is a problem in that if the pipe 6 is long, the degree of contamination from the pre-sample remaining on the inner wall of the pipe 6 becomes high, and a large amount of cleaning liquid is required. Moreover, there is no suggestion of a cleaning mechanism that performs a cleaning operation by suctioning a cleaning liquid. Furthermore, since the tube is precessed while adding the reagent little by little, there is also the problem that the stirring effect is weak. Further, the stirring mechanism includes a motor 12, a rotating case 13, and a tube 1.
1. Consisting of a fulcrum 10, the structure is complicated with many parts, and the spout pipe cannot be shortened.
Furthermore, since the stirring rod 4 (or tube 11) and the suction tube 9 are separate, they require a large space and have to be separated if they are to be cleaned.

何ら示唆されていない。 In addition, the mechanism described in Japanese Utility Model Laid-Open Publication No. 52-83784 has the problem that the position of the container is unstable due to the balance of the lever, and processing such as stirring cannot be performed stably. Furthermore, the technical idea of using a mixing rod and a sample suction pipe in combination is not suggested at all.

が好ましい。Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a fixed base provided horizontally or approximately horizontally, and a pulley-shaped rotating body 4 projects from the upper part of the fixed base 1 through a hole 2 through a bearing 3 or the like. It is rotatably fitted. This pulley-like rotating body 4 has a through hole 5 located at a position slightly offset from the central axis and having a diameter slightly larger than that of the sample stirring/suction pipe described later.
is provided. A sample stirring/suction pipe 6 whose upper end is connected to the suction means of the automatic analyzer is inserted into the through hole 5 so that its upper and lower ends protrude. Further, the upper part of the pulley-like rotating body 4 is connected to a rotating shaft 10 of a drive device such as a motor 8 via a belt 7 or the like.
Note that the lower part of the pulley-like rotating body 4 may be made to protrude from the fixed base 1, and the belt may be provided below the fixed base 1. The rotation of the motor 8 is transmitted to the pulley-like rotating body 4 via the belt 7, and when the pulley-like rotating body 4 rotates, the sample agitation/suction pipe 6 rotates because the through-hole 5 is provided at an eccentric position. Do exercise. At this time, the sample stirring/suction pipe 6 only performs circular motion in a position regulated by the through hole 5, and the sample stirring/suction pipe 6 does not rotate.
Reference numeral 11 denotes a nut screwed onto the lower part of the pulley-like rotating body to prevent the pulley-like rotating body from coming off. The sample stirring/suction pipe 6 is preferably made of a material such as fluororesin, which has excellent chemical resistance, abrasion resistance, and elasticity.

される。 In the apparatus configured as described above, the loader 13 is moved intermittently to transfer the sample container 12 containing each sample to the position directly below the sample stirring/suction pipe 6. Then, the sample container vertical movement device 15 is operated to lift the sample container 12 to a predetermined position (a position where the lower part of the sample stirring/suction pipe 6 is immersed in the sample). Subsequently, the motor 8 is operated to cause the sample stirring/suction pipe 6 to perform a stirring motion. This stirring motion produces the same effect as stirring with a glass rod, etc., and the sample is sucked into the automatic analyzer through the sample stirring/suction pipe 6 in a uniformly stirred state, allowing dilution and reagent removal. Addition and analytical measurements are made. When the sample is aspirated, the sample container vertical movement device 15 is activated to lower the sample container 12.
is returned to its original position, and then the loader 13 is operated to replace the sample container containing the next specimen. on the other hand,
The cleaning device 17 is for cleaning the previous sample adhering to the sample agitation/suction pipe 6 after sample suction or the pipes inside the analyzer.At the same time as the sample container vertical movement device 15 descends, the cleaning device 17 The cleaning tank 17 moves to a position where the sample stirring/suction pipe 6 can suck the cleaning liquid, and sucks the cleaning liquid sent from the cleaning liquid supply pipe 18. At this time, the motor 8 is activated again and the sample stirring/suction pipe 6 is stirred, so that the sample adhering around the sample stirring/suction pipe 6 is also completely washed away.

図および第２図の場合と同様である。 Further, as shown in FIG. 3, instead of the pulley-like rotating body 4, the bottom of a hollow cylindrical pipe 20 is sealed, and the bottom of the hollow cylindrical pipe 20 is placed at an eccentric position in the same way as in the case of the pulley-like rotating body. A pipe-shaped rotating body 22 provided with holes 21 may be provided. Other configurations are first
This is the same as in the case of FIG.

魔になつたりすることが避けられる。 The apparatus shown in FIG. 3 not only automatically supplies samples using the loader 13, but also handles cases where a sample that requires urgent manual inspection is inserted, or when the opening of the sample container is narrow. For example, the device of the present invention can effectively operate even for test tube type containers, and since the movement of the sample stirring/suction pipe 6 is regulated at a lower position, the sample stirring/suction pipe 6 can be used more easily than necessary. The position of the fixing base 1 can be prevented from shifting to the side, and the fixing base 1 can be prevented from getting in the way when inserting the sample stirring/suction pipe into the opening of the sample container.

ている。Effects of the invention As explained above, the device of the present invention makes it possible to aspirate a stirred and homogeneous sample in an extremely short period of time. No longer needed. Furthermore, since the pipe 6 is eccentrically rotated by direct stirring with the sample stirring/suction pipe and rotating the rotating body 4, there is no need for a fulcrum as in the structure described in JP-A No. 52-28390. First, the length of the pipe 6 can be made much shorter than that described in this publication, and it also serves as a sample suction pipe and a stirring rod, so it is compact, takes up less space, and is easy to clean. Therefore, contamination (mutual contamination between samples) can be prevented. In addition, in the event that you need to replace the sample stirring/suction pipe, you can easily remove just the sample stirring/suction pipe, and if you perform high-speed stirring, even highly viscous samples can be easily homogenized. It has several advantages.
