Problems solved by technology

[0004] In addition, at the mixing position of cuvette cleaning, if the magnetic beads are mixed evenly by eccentric oscillation, the eccentric sleeve interferes. Usually, no magnet or a smaller magnet is installed at the mixing position, resulting in the adsorption of magnetic beads. less effective

Abstract

The invention discloses a reaction cup cleaning device and a sample analyzer. The reaction cup cleaning device comprises a mounting rack, a reaction cup disc, a cleaning mechanism, a lifting mechanism and a driving component, wherein the lifting mechanism is used for driving the cleaning mechanism to ascend and descend; the driving component is mounted on the mounting rack and is used for driving the reaction cup disc to rotate; holding holes for holding reaction cups are formed in the reaction cup disc; the cleaning mechanism comprises a needle component, needle cleaning tanks for cleaning liquid sucking needles, and a cleaning driving mechanism; the needle component comprises the liquid sucking needles and cleaning needles; the cleaning driving mechanism is used for driving the needle component to move in a reciprocating manner; when being driven to move to a first final point, the needle component is positioned above a holding hole of a cleaning position; when the needle component is driven to move to a second final point, the liquid sucking needles are positioned above the needle washing tanks. By adopting the reaction cup cleaning device, the rates that the liquid sucking needles are not completely cleaned and are subjected to cross pollution are reduced.

Description

technical field [0001] The invention relates to the technical field of sample analysis, and more specifically, to a cuvette cleaning device and a sample analyzer. Background technique [0002] The cuvettes used in sample analysis have magnetic beads to which the substance to be measured is bound. During the analysis process, the cuvette needs to be cleaned. Since the cuvette contains magnetic beads, the cleaning of the cuvette is relatively complicated. [0003] To clean the cuvette, the magnetic beads are usually adsorbed to the wall of the cuvette by an external magnetic field, and then the remaining substances in the cuvette are removed to achieve the purpose of cleaning. At present, during the cleaning process of the cuvette, the aspiration needle is cleaned when the cleaning solution is filled into the cuvette at the cleaning position, and the probability of cleaning the aspiration needle is relatively high, and the probability of cross-contamination between the aspira...
