Abstract: This disclosure provides automatic analyzers and reagent wheels thereof. The reagent wheel can have one or more rings of reagent bottle seats that may be used for placing a reagent container and distributed along a circumferential direction. An included angle may be formed between a symmetrical centerline of the reagent container placed on the reagent bottle seat and a radius of a circle where the reagent wheel is located, where the included angle is not equal to zero. Compared with the situation in which the symmetrical centerline of the reagent container overlaps with the radius of the circle where the reagent wheel is located, an improved balance can be achieved between the capacity and the diametric size of the reagent wheel, thus making an improvement in meeting application requirements of the analyzers.

Abstract: Some embodiments of the present invention provide an anti-collision device used for a sample-loading system. This device may include a code plate, an optical coupler, a location signal-detecting unit, a drive pulse counting unit and a drive pulse-sending unit. The optical coupler detects the code plate during the relative movement between the optical coupler and the code plate and outputs detection signals. The location signal detecting unit determines whether to output location signals to the drive pulse counting unit. The drive pulse counting unit judges whether collisions occur to the sample-loading system. Some embodiments of the present invention provide an anti-collision method and a sample-loading system comprising the anti-collision device.
