The invention relates to the sampling and the mixing device in the fully automatic biochemical analyzer which includes the angle cantilever device and the driving device. The angle cantilever device which includes the sampling arm, the mixing arm is fixed on the driving device by the locknut. One end of the sampling arm is set with the sampling needle holder and the sampling needle fixed in the lower end, the other end is connected to one end of the mixing arm by the connecting part, the other end of the mixing arm is set with the mixing needle rotary driving motor and the mixing needle fixedon the lower end. The sampling and mixing arms are drive by one set of driving device. The invention can not only shorten the working time but make the working table simple and improve the product technique layer / content.
Description
technical field [0001] The invention relates to a sampling and stirring device in a fully automatic biochemical analyzer, in particular to a sampling and stirring integrated device of a fully automatic biochemical analyzer. Background technique [0002] In a fully automatic biochemical analyzer, both a sampling device and a stirring device are necessary. The main function of the sampling device is to absorb and release samples or reagents; the main function of the stirring device is to stir the samples or reagents released into the reaction cup to ensure the uniformity of the reaction and the accuracy of the test results. [0003] At present, the structure and movement modes of the sampling device and the stirring device in the existing automatic biochemical analyzers are generally similar or the same, that is, the sampling device and the stirring device are separated, each forming a set of mechanisms, and the action process is controlled separately, independent of each othe...
