In one embodiment, it as shown in figure 9, the blank plates taken out from storehouse 52 push to sample-adding local area 11, holds The lath for being loaded with the solution comprising sample to be tested pushes to reagent adding area 12 from sample-adding local area 11 and carries mixed solution Lath pushes to the first incubation unit 21 from reagent adding area 12 and is completed by same delivery device, which is denoted as the 5th and pushes away Mechanism 30 is sent, structure can be identical as the first delivery device 4, can also be identical as the 4th delivery device 50.

It should be understood that above-mentioned push step can also be realized by three independent delivery devices respectively, although independent Three kinds of delivery devices can increase the flexibility that detector transports lath, but this kind setting will increase the complexity of mechanical structure Property, cause detector volume to increase, while manufacturing cost increases.

In this embodiment, it is moved to the second incubation unit 22 from the first incubation unit 21 via the second transhipment channel 23, And be moved to detection module 3 via third transhipment channel 24 from the second incubation unit 22 and also completed by same delivery device, it should Delivery device is denoted as the 6th delivery device 40, and structure can be identical as the first delivery device 4, can also be with the 4th delivery device 50 is identical.

Above description is merely a prefered embodiment of the utility model, but scope of protection of the utility model is not limited to This, any those skilled in the art can be easy to carry out and be altered or varied in technical scope disclosed by the utility model, and This be altered or varied should be covered within the scope of the utility model.Therefore, the protection scope of the utility model is answered Subject to the scope of protection of the claims.
