High-speed magnetic washing incubation light measuring device

Abstract

The invention discloses a high-speed magnetic washing incubation light measuring device, which comprises a bottom plate and a continuous conveying mechanism, wherein the continuous conveying mechanismcomprises a reaction cup conveying track positioned on the bottom plate, a driving disc which is arranged above the reaction cup conveying track and has a plurality of through grooves crossed with the reaction cup conveying track, a transmission mechanism used for enabling the driving disc to move in the conveying direction of reaction cups, wherein a liquid suction mechanism, a linkage grabbingand uniform mixing mechanism and a light measuring mechanism are further arranged on the peripheral side of the reaction cup conveying track. The high-speed magnetic washing incubation light measuringdevice is ingenious in structure, small in occupied space, low in investment cost, safe, reliable and low in failure rate, automatic transfer of reaction cups from a previous station to a next station is achieved through cooperation of the track and a driving piece, positioning is accurate, rapid and efficient; and related mechanisms such as magnetic washing, substrate filling, even mixing, lightmeasuring and discarding are integrated on the track along the way, and the overall efficiency of sample light measuring can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of in vitro diagnostic instruments, in particular to a high-speed magnetic washing incubation photometry device. Background technique [0002] Most of the in vitro diagnostic equipment such as automatic chemiluminescent immunoassay system, biochemical analyzer, laboratory assembly line, nucleic acid, etc. will involve photometric detection of samples. Before photometry and detection, pretreatment operations such as magnetic washing, substrate filling, mixing, and incubation are required for the sample. The existing device needs to transfer the sample cuvette through the gripper between each work, and there are many grippers. The setting of the hand leads to large equipment volume and high investment. At the same time, the cuvette rotation frequency is high. When the gripper is used to grasp the cuvette, the running speed of the cuvette is slow, resulting in low overall efficiency of photometry and detection....
