Problems solved by technology

[0002] There are currently many ways to obtain exfoliated cells contained in body fluids, such as sedimentation, centrifugation, filtration, etc. These methods are generally only applicable to body fluid samples with a small sample size and a large number of cells in the sample, but for body fluid There is no effective and convenient method for rapid processing of body fluids with a large amount but a small amount of cells, to obtain the exfoliated cells in these body fluids, and to recycle and store them for subsequent medical tests by the pathology department

Embodiment 1

[0022] Using the above-mentioned device for conveniently collecting exfoliated cells in a large amount of body fluids, the method for collecting and processing cells of a large amount of body fluid samples includes the following steps;

[0023] In step 1, the body fluid sample to be collected from the exfoliated cells is added through the external liquid inlet of the body fluid sample storage container 11 .

[0024] Step 2, the liquid discharge chamber 5 is connected with the liquid inlet chamber 2 through the interchangeable interface 10 to form a whole.

[0025] Step 3, lifting the body fluid sample storage container 11, so that the body fluid sample flows to the conical cell filter membrane 4 under its own gravity, flushing the conical cell filter membrane 4 from top to bottom, so that the cells in the sample remain on the filter membrane, and the waste liquid Drain the drain chamber 5.

[0026] Step 4, when the above-mentioned body fluid samples are all discharged from th...

Abstract

The invention relates to a device for conveniently collecting exfoliated cells in a large amount of body fluids. The device comprises a sharp-bottomed cell collection bottle filled with a cell elutionpreserving fluid. The device for conveniently collecting the exfoliated cells in a large amount of the body fluids is characterized by consisting of a specimen storage container and a liquid inlet cavity in the upper part, a liquid discharge cavity provided with a conical cell collection filter membrane and a lower port sealing cover and formed in the lower part, and the sharp-bottomed cell collection bottle filled with the cell elution preserving fluid. According to a method and the device disclosed by the invention, the device is simple to operate, the liquid discharge cavity in the lower part, the liquid inlet cavity in the upper part and the sharp-bottomed cell collection bottle can be quickly and conveniently assembled and disassembled through intercommunication interfaces, so that the exfoliated cells in a large amount of the body fluids can be easily collected, and a method for obtaining the cells in the body fluids is greatly simplified.

Description

technical field [0001] The present invention relates to how to conveniently collect detached cells in a large amount of body fluids, and rapidly elute and preserve the obtained cells, and perform subsequent centrifugation to obtain cell aggregation particles or perform smear staining. Background technique [0002] There are currently many ways to obtain exfoliated cells contained in body fluids, such as sedimentation, centrifugation, filtration, etc. These methods are generally only applicable to body fluid samples with a small sample size and a large number of cells in the sample, but for body fluid There is no effective and convenient method to quickly process the body fluids with large volume but few cells, obtain the exfoliated cells in these body fluids, and recover and store them for subsequent medical examination by the pathology department. Contents of the invention [0003] In order to overcome the defects in the prior art, the present invention proposes a device ...
