Abstract
The invention relates to a full-automatic combined blending method and a device thereof, which adopt two blending modes of non-contact oscillation blending and sampling needle blending and a blending device to sequentially carry out two different blending treatment modes on a reaction reagent. The oscillation mixing is that under the condition that the running direction of the eccentric structure in the direction of the motor is not changed, the movement direction and the movement acceleration and deceleration change in the process that the reaction cup or the reagent chip performs reciprocating movement in the horizontal direction, so that the liquid in the reaction cup is overturned up and down to further enable the solution to achieve the relatively uniform effect. And the sampling needle is directly used for stirring the liquid after uniformly mixing the sampling needles, so that the relative movement between the solutions is accelerated, and the solution can achieve the relatively uniform effect. The combination of the two modes not only improves the mixing efficiency of the reaction reagent, but also solves the technical problems that the mixing device in the existing in-vitro diagnostic instrument has narrow application range, cannot give consideration to various liquid phase reagents and has poor mixing effect.
