Pretreatment tube and pretreatment method for liquid-based cell sample

Abstract

The invention relates to the technical field of medical treatment, in particular to a pretreatment tube and a pretreatment method for a liquid-based cell sample.The pretreatment pipe comprises a pipe body; a pair of slots which are formed in the inner wall of the pipe body; an inserting plate, the width of the inserting plate is matched with the spacing distance of the pair of inserting grooves, and the inserting plate is used for being embedded into the pair of inserting grooves so as to divide the pipe body into a first cavity and a second cavity which are closed with each other; a filter membrane is arranged on the insertion plate and is provided with a plurality of filter holes, and the size of the filter holes is smaller than that of the cells to be treated. According to the technical scheme, the pretreatment tube has the beneficial effects that the insertion plate is arranged in the tube body of the pretreatment tube to divide the tube body into the first cavity and the second cavity, and the insertion plate is provided with the filter membrane with the filter holes, so that the tube body is not only used for storing cell samples, but also can realize other reaction functions such as dilution, enrichment and dyeing in the tube body.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a pretreatment tube and a pretreatment method for a liquid-based cell sample. Background technique [0002] The test tube structure in the prior art is relatively simple, it is only used as a container for sample collection, usually only a tube body with a cavity inside, in some occasions it can be used with a tube cap, generally it can only be placed in a special device For operations such as centrifugation, the use function is relatively simple. [0003] In the prior art, the demand for detection of cells to be treated, such as urine, cervical cell fixative, pleural and ascites, etc., is becoming more and more common, while the detection of cells to be processed often requires enrichment and fixation of cell samples. For test operations such as staining and staining, the above-mentioned complicated operation functions cannot be realized by using ordinary single-function test ...
