When the reagent is sucked, the reagent box on the reagent disk is rotated to the position where the reagent needle needs to suck the reagent through the rotation of the reagent disk, and then the reagent in the reagent box is sucked into the incubation disk through the reagent needle to react with the sample. Generally, reagent boxes on a reagent tray have different structures such as a split type structure and an integrated type structure, as shown in fig. 1, a plurality of mutually independent reagent containing cavities 2 are arranged in an integrated type reagent box 1, an opening at the upper end of each reagent containing cavity 2 is convenient for a reagent needle to absorb a reagent, and different types of reagents are filled in each reagent containing cavity 2; a plurality of reagent boxes are arranged on the reagent disk, and the rotation of the reagent disk can drive the plurality of reagent boxes to rotate together. Among the reagents, there is a reagent (such as magnetic bead reagent, immunomagnetic bead, magnetic bead solid phase carrier) which is easy to precipitate and accumulate due to its characteristics, and it needs to rotate continuously during the test absorption process to prevent the precipitation and accumulation. However, in the existing integrated reagent kit, only when the reagent disk rotates, the reagent kit can rotate together with the reagent disk, the reagent in the reagent kit also moves together with the reagent disk, and when the reagent needle sucks the reagent from the reagent kit, the reagent disk and the reagent kit cannot move, so that the reagent easy to precipitate and accumulate in the reagent kit stops rotating, and thus, the precipitation and accumulation phenomenon is easy to occur in the process of sucking the reagent, and the test result is influenced.

As shown in fig. 3, 14 and 15, the specific driving and rotating process of the present embodiment is as follows: firstly, controlling a first driving motor of a first power mechanism to act so as to sequentially drive a first driving gear, a driving belt 9, a main gear 8 and a main shaft 7 to rotate, and finally driving a turntable 4 to rotate through the rotation of the main shaft 7; at this time, the second driving motor 21 does not operate, and the turntable 4 drives the lower gear 172 of the first transmission mechanism 17 connected to the reagent tube 16 to rotate along the outer ring gear of the bidirectional gear ring 20, so as to drive the reagent tube 16 containing the magnetic bead reagent to rotate. Here, the second driving motor 21 is preferably a servo motor of a brake device, and is similar to a motor structure of a winch, when the turntable 4 rotates, the bidirectional gear ring 20 can be controlled to be fixed by the brake device, so that when the lower gear 172 of the first transmission mechanism 17 rotates along the outer ring gear of the bidirectional gear ring 20, the rotation speed is faster, and the rotation speed of the reagent tube 16 is also faster.

When a certain reagent box needing to absorb reagent on the rotary disc 4 rotates to the position, the first control driving motor stops, the rotary disc 4 stops rotating, at the moment, the second control driving motor 21 acts, so that the driving gear 211 is sequentially driven, the bidirectional gear ring 20, the lower gear 172 of the first transmission mechanism 17, the connecting shaft 173 of the first transmission mechanism 17 and the upper rotary disc 171 of the first transmission mechanism 17 rotate, finally, the reagent tube 16 is driven to rotate through the rotation of the upper rotary disc 171 of the first transmission mechanism 17, and therefore when the rotary disc 4 is ensured not to rotate, the reagent tube 16 containing magnetic bead reagent can continuously rotate, and the phenomenon of deposition and accumulation cannot occur.

In the embodiment, the reagent cartridges and the openings thereon are arranged in an arc shape, and the plurality of arc-shaped reagent cartridges are sequentially arranged on the reagent tray along the circumferential direction of the reagent tray, as shown in fig. 8 and 18, so that each opening is located on the movement track L of the reagent needle 28, and therefore, in the action of sucking the reagent, the reagent needle 28 only needs to sequentially suck along the movement track L, and no redundant action is needed, thereby greatly improving the detection efficiency.

As shown in fig. 2 and 9, a code scanning window 23 is opened on the circumferential surface of the housing body 311, and an identification code 24 is provided on the end surface of the box body 111 of each reagent box, where the identification code 24 may be a barcode or a two-dimensional code.

Through the specific structural design of the first transmission mechanism and the second transmission mechanism, the continuous rotation function of the reagent tube is further ensured. The rotating angle position of the rotating disc can be monitored and controlled in real time by arranging the induction disc and the sensor, so that the specific rotating position of the reagent kit on the rotating disc can be controlled. Through all being the arc setting with the opening two of a plurality of openings on every kit and reagent pipe, like this for just can make the movement track of reagent needle and open-ended arc arrange the position and coincide mutually, the reagent needle of being convenient for more absorbs reagent, shortens and absorbs the time, improves work efficiency.

The term "plurality" as used in this embodiment means a number of "two or more". The above embodiments are provided only for the purpose of illustration, not for the limitation of the present invention, and those skilled in the relevant art can make various changes or modifications without departing from the spirit and scope of the present invention, so all equivalent technical solutions should also belong to the protection scope of the present invention, and the protection scope of the present invention should be defined by the claims.
