Description

Technical Field

[0001] The present invention relates to the technical field of reproductive secretion sampling instruments, and in particular to a reproductive secretion sampling device. Background Art

[0002] Vaginal secretion testing is a basic procedure used to assist in the diagnosis of vaginitis by detecting changes in the internal environment of the female reproductive tract or infection. According to the "Guidelines for Standardized Clinical Examination and Reporting of Vaginal Discharge," sampling instruments must be clean, dry, sterile, and free of chemicals or lubricants. Depending on the test item, one to three sterile swabs are rotated along the upper third of the vaginal wall to ensure that secretions are clearly visible on the swab.

[0003] At present, sampling is basically carried out using sterile swabs, and in order to ensure the maximum scraping degree, the sterile swabs are mostly brush-shaped. During sampling, even if the swab is coated with lubricant, it will still cause more or less discomfort or even pain to the patient. In addition, due to the different degrees of differences in the genital structure of patients, the swab often cannot properly contact the secretions, resulting in the need for multiple sampling. Based on the above-mentioned viewpoints, those skilled in the art have proposed a reproductive secretion sampling device that can solve the above problems. Summary of the Invention

[0004] In view of the defects of the current sampling swabs mentioned in the above background technology that scraping sampling causes discomfort and cannot be recycled, a technical solution of a reproductive secretion sampling device is provided.
