Cell concentration system and method

Abstract

The invention discloses a cell concentration system. The cell concentration system comprises a sample bottle, a concentration mechanism, a rotating mechanism and a controller, wherein the sample bottle is used for storing a liquid sample; the concentration mechanism can penetrate through the bottom part of the sample bottle to concentrate a liquid sample in the sample bottle; the rotating mechanism can be matched with the bottom part of the sample bottle to execute rotary operation; the concentration mechanism and the rotating mechanism are arranged at the same working position, and can move relatively and independently; the controller controls penetration of the concentration mechanism from the bottom part of the sample bottle, controls the rotating mechanism to act on the bottom part ofthe sample bottle and controls the rotating mechanism to carry out one-way rotating operation. The cell concentration system disclosed by the invention has the beneficial effects that by execution ofsuctioning operation and reverse blowing operation and execution of one-way rotating operation after reverse blowing operation, the deposition of bubbles caused by reverse blowing operation can be effectively inhibited and the risk of pollution due to overflowing of excessive bubbles can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of medical bioassays, and more specifically relates to a cell concentration system and method. Background technique [0002] In medical testing, it is often necessary to enrich a specific cell in the specimen, and then identify the cells. In order to ensure the accuracy of the test and the number of cells required for the test, it is usually necessary Enrichment is carried out under certain conditions, which can prevent infection and pollution, and ensure the safety of operators and the surrounding environment. [0003] At present, liquid-based products on the market usually obtain samples through a sampling brush, then put the sampling brush into the sample bottle, add cell preservation solution into the sample bottle, and rotate or invert the sample bottle to make the sample bottle The cell preservation solution and the sampling brush move relatively to generate shear force, and the cell samples on the sa...

Problems solved by technology

Especially in automated instruments, after the cell samples are obtained from the sampling brush, the cells need to be enriched before the concentrated cells can be sucked to make slides. During the enrichment process, the pore size is often used However, when collecting cell samples, not only are all cell samples collected, but also some tissue mucus, and in the process of filtering with a filter membrane, the tissue mucus may block the filter membrane. In the process of dredging the pores of the filter membrane, it will cause bubbles in th
