A kind of cervical brush and its manufacturing process

Abstract

The invention proposes a cervical brush and a manufacturing process thereof. The cervical brush includes a brush handle, a fixing piece and a brush head, the brush head is provided with a connecting rod and bristles, the connecting rod is provided with a blocking position and a terminal, and the terminal is provided with a There are round ends and collecting parts. The manufacturing process of cervical brush is as follows: through screening the brush head, making the end, drying and shaping the end, processing the connecting rod, heating the connecting rod, installing the brush handle, and effectively wrapping the wire. The brush head is firmly fixed on the brush handle. After successful installation, the quality and sanitation of the cervical brush are guaranteed through quality inspection, overall sterilization and cervical brush packaging; the manufacturing process of this cervical brush can firmly connect the brush head and the brush The fixed connection of the handle improves the stability of the plug-fit connection, the round end on the brush head effectively provides the user with a basis for judging the insertion depth, and the collection part can effectively collect the cells on the inner wall of the bottom of the uterus , to help patients get deep into the inner wall cells of the uterus.

Description

technical field [0001] The invention relates to the technical field of cervical brush manufacturing, in particular to a cervical brush and a manufacturing process thereof. Background technique [0002] Cervical brush is a medical device used for gynecological cervical examination. It is generally composed of a brush handle and a brush head. The installation method of the cervical brush on the market is that the front end of the brush handle and the tail end of the brush head are connected by thread or plugged in. Connection, for example: the cervical brush with patent No. CN2482969Y is threaded connection, while the cervical brush with patent No. CN201064453Y is plug-fit connection; [0003] However, in the production of the brush head of the cervical brush, the production cost of the production method of folding the iron wire in half and intertwining and locking the bristles (similar to the shape of a twisted twist) is low. This method of producing the brush head is greatly...

AI Technical Summary

Problems solved by technology

In the prior art, when the end of the cervical brush is not processed, when the cervical brush penetrates into the uterus for sampling, due to the physical differences of each patient, the end of the brush is likely to cause the user's tingling sensation during the in-depth process. Discomfort; at the same time, the hard end also magnifies the patient's discomfort;

[0005] In this field, the cervical brush scrapes and samples the cells of the cervix through the bristles, and sticks them through the bristles. During the process of taking out the cervical brush, some of the cells have been stuck and will fall off, resulting in low sampling efficiency.
