Problems solved by technology

Recently, some domestic companies have also developed liquid-based cell thin-layer film-making and staining machines suitable for their own national conditions, such as the LCT detection equipment of Guangzhou Anbiping Company (Application No. ), but judging from the clinical test results, there is still a big difference compared with foreign LCT technology, and the production quality is far from that, which is mainly reflected in: after installing the suction nozzle for the injection needle, it is necessary to set an additional suction The bracket of the nozzle occupies a large space and position, and the position where the nozzle is taken out is fixed, and accumulation will form after being taken out by the bracket, which hinders the flexible recovery of the nozzle

Abstract

The invention discloses a recovery device for a suction nozzle. The recovery device comprises a sample-adding needle, a suction nozzle, a baffle base, a waste box, a Z1 axis bracket and a Z1 axis driving mechanism, wherein the baffle base is fixedly arranged at the bottom end of the Z1 axis bracket; the sample-adding needle is in sliding fit with the Z1 axis bracket along the Z axis direction; the Z1 axis driving mechanism is in driving connection with the sample-adding needle and is used for driving the sample-adding needle to vertically slide; the sample-adding needle is sleeved on the baffle base in a sliding form; correspondingly, the baffle base is provided with a penetrating hole, into which the sample-adding needle can be penetrated; the top end of the suction nozzle is detachably sleeved on the bottom end of the sample-adding needle; the top end of the suction nozzle is in resisting fit with the penetrating hole; the waste box is used for recovering the suction nozzle. The invention also discloses a dyeing machine adopting the recovery device for the suction nozzle. The recovery device for the suction nozzle can effectively save space.

Description

technical field [0001] The invention relates to cytopathological detection technology, in particular to a suction nozzle recovery device and a dyeing machine. Background technique [0002] Liquid-Based Cytology Test (LCT for short) technology is mainly used in cervical cytology detection, especially for cervical cancer screening. [0003] Its working principle is: scrape the exfoliated cells of the cervix with a special sampling device and wash them all into a plastic bottle filled with cell preservation solution, send them to the laboratory, and deaggregate the cell clusters after being evenly shaken with a stick, and store the cell specimens. The liquid is centrifuged and precipitated to separate the cervical epithelial cells from the cell fragments, blood, mucus, white blood cells and other impurities in the specimen to obtain pure cervical epithelial cells. Through cell transfer technology, the cervical epithelial cells are transferred to slides to make A thin layer of ...
