Flow guide centrifuge tube for liquid based cytology slice production

Abstract

The invention discloses a flow guide centrifuge tube for liquid based cytology slice production. The flow guide centrifuge tube comprises a centrifuge tube body and a centrifuge tube cover, wherein atube wall with an opening is arranged at one end of the centrifuge tube body; the other end of the centrifuge tube body is a circular arc-shaped or conical tube bottom; four inducers vertical to the opening end of the tube wall are arranged at the inner wall of the tube body and extend to the tube body from the tube wall of the opening end; the parts, near the opening end of the tube wall, of theinducers are inclined surfaces. The flow guide centrifuge tube has the beneficial effects that through the arrangement of the inducers extending to the tube bottom from the opening end and the arrangement of the positions near the opening end of the tube wall into the inclined surface, a sampling brush head remained inside the tube body in the sample centrifugation process can be scraped with theinducers; at the moment, the sample cells on the sampling brush can be conveniently and sufficiently transferred into the centrifuge tube body and can be accumulated onto the tube bottom along with the inducers under the effect of centrifugation force.

Description

technical field [0001] The invention relates to the technical field of medical pathological cytology detection, in particular to a diversion centrifuge tube for liquid-based cytology preparation. Background technique [0002] In medical pathological examination, liquid-based thin-layer cytology detection technology has gradually become the main method for gynecological cervical cancer detection. A key technical link of liquid-based thin-layer cytology detection technology is the collection of sample cells. Pour the preservation solution with a sampling brush head into a centrifuge tube, and after centrifugation in a centrifuge, use a straw to suck up the samples accumulated at the bottom of the centrifuge tube cell. The extracted sample cells are made into a thin-layer smear by a cell film machine. The smear cells produced by this method are evenly distributed, with less cell overlap, and reduce components such as mucus protein, red blood cells, and other impurities that hi...

AI Technical Summary

Problems solved by technology

[0005] After the sampling brush collects the cells from the cervix, in most cases the brush head is covered with mucus protein at the same time. cells, which is not conducive to transfer the sample cells to the bottom of the tube and accumulate at the bottom of the tube under the action of centrifugal force, thus affecting the collection amount of sample cells
