Problems solved by technology

[0003] These collection tools have their own advantages and disadvantages: the cervical scraper is a spatula-shaped scraper made of wood or plastic. It is not easy to collect all the specimens on the surface of the cervix, especially the cells in the cervical folds
U.S.Pat.No.5370128 keeps the bristles in the shape of "mountain", but replaces the bristles in the middle with the head of the cell brush, which greatly enhances the effect of taking materials from the cervical canal, but the bristles of the cell brush and the cervical brush The direction of the bristles of the cervical brush is perpendicular to each other, and none of them is perpendicular to the surface of the mucous membrane. Poor contact, and the part of the cervical brush of this design just corresponds to the high incidence of lesions at the junction of the squamous epithelium and columnar epithelium of the cervix.

Abstract

A uterine cervix sampler for sampling from the mucosa on the surface of uterine cervix is composed of brush head, brush handle and connecting mechanism between brush head and brush handle. Said brush head has E-letter shape consisting of two L shapes, on which there is a sampling material.

Description

technical field [0001] The invention relates to a cervical sampling device used for collecting cervical mucous surface testing materials during gynecological cytology examination. Background technique [0002] Early lesions of cervical cancer are difficult to identify with the naked eye, and when they can be identified with the naked eye, they often have developed into advanced cancer. The method of cervical cytology to check early cervical lesions is effective, so that the mortality rate caused by cervical cancer is greatly reduced. The first step in clinical cervical cytology is specimen collection. The most primitive method is to use a cotton swab to swab the surface of the cervical mucous membrane, apply it on a glass slide, and then perform microscope observation and analysis after Papanicolaou staining, or do other laboratory tests. When taking materials with cotton swabs, the cells stuck to it are not easy to be completely separated, and the observed cells are easil...
