Abstract

The invention provides a swab and a preparation method and application thereof. The swab includes swab sampling heads, a hollow swab tube (3) and a partition belt (4). The first sampling head (1) andthe second sampling head (2) are arranged at the two ends of the hollow swab tube respectively, and the partition belt (4) is arranged in the middle of the hollow swab tube. According to the providedswab, the double-end swab is adopted for combining two detection methods onto one swab body, the structure is simple and convenient, a swab rod in a traditional swab is substituted by the hollow swabtube, and the hollow swab tube is sealed and separated into two parts which are not communicated with each other by means of a hot-pressing technology and can be used for injection of liquid. By extruding the hollow tube, the liquid can permeate into the sampling heads, and by using the swab for detecting vaginal diseases, the accuracy of a detection result is extremely high.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary instruments, and mainly relates to a swab and its preparation method and application. Background technique [0002] In today's society, women's life rhythm is getting faster and faster, and various work and life pressures have caused more and more women to suffer from gynecological diseases. Bacterial vaginosis is caused by the imbalance of flora in women's vagina, and it is also one of the common diseases in obstetrics and gynecology. Women with bacterial vaginosis often have increased leucorrhea accompanied by abnormal odor. Such patients are prone to uterine inflammation, Adnexitis, pelvic inflammatory disease, ectopic pregnancy, infertility and other diseases will reduce the quality of life and greatly interfere with women's physical and mental health. It has been clinically proven that in a weakly acidic environment for women, the pH value of the vagina is about 3.8-4.5, which is c...
