Problems solved by technology
Among them, the automatic quantitative analyzer is the most commonly used real-time detector based on the use of plane scanning detection. The existing automatic quantitative analyzer has defects in actual use. When the sampling needle draws blood samples, the blood collection tube does not There is a very good low pressure, which leads to the separation of the sampling needle from the rubber cap of the blood collection tube, tilting or shaking, which increases the leakage of biological pollutants, or rarely has a mechanism that resists the pressure of the blood collection tube, but it can only resist Press one type and specification, if the specification of the blood collection tube is different, it cannot be used, which will cause inconvenience in use

The invention discloses a pressure tube mechanism of a fully automatic immunological quantitative analyzer, which comprises a turntable mechanism for fixing a blood collection tube; a moving needle pricking mechanism with a sampling needle; On the tube base, the screw rod and the pressure tube motor are connected through a coupling, the two ends of the screw rod are fixed by the fixed end bearing seat and the movable end bearing seat, the blood collection tube pressure plate is connected to the screw rod through the screw nut clamp block, and the induction device is fixed On the blood collection tube press plate, it is used to sense and judge the length of the blood collection tube. Driven by the pressure tube motor, the blood collection tube press plate makes a linear motion in the vertical direction along the precision slide rail, and is used to press the blood collection tube on the turntable mechanism, and move the needle When the sampling needle of the mechanism is completely detached from the rubber cap of the blood collection tube, the pressure plate of the blood collection tube is reset to the in-position sensing device. The tube pressing mechanism can automatically sense and judge blood collection tubes of different lengths and perform corresponding pressing as required, and is flexible in operation and convenient in use. The invention also provides a pressing method.
Description
Technical field [0001] The invention relates to the technical field of an immune quantitative analyzer, in particular to a pressure tube mechanism of an automatic immune quantitative analyzer and a compression method thereof. Background technique [0002] At present, POCT has been widely used in the field of reagent detection technology at home and abroad because of its simple and rapid characteristics. Among them, the automatic immunoquantitative analyzer is the most commonly used real-time detector based on planar scanning detection. The existing automatic immunoquantitative analyzer has defects in actual use. When the sampling needle is drawing blood samples, the blood collection tube is not There is a very good low pressure, which causes the sampling needle to be separated from the rubber cap of the blood collection tube, tilting or shaking, increasing the leakage of biological contaminants, or there is a mechanism to resist the pressure of the blood collection tube, but only...
