Description

Vaginal dilator assisting in collecting posterior fornix secretion

Technical Field

The utility model relates to the technical field of medical equipment, more specifically say so and relate to an supplementary dome secretion collection vaginal dilator behind.

Background

Genital tract infection is a common disease and frequently encountered disease of women, is a general name of a large class of diseases causing female genital tract infection by invasion of pathogens such as various bacteria, viruses, candida, trichomonas, chlamydia, mycoplasma and the like, generally comprises various vaginitis, gonorrhea, cervicitis, pasteurella cysts, pelvic inflammation and the like, and has the characteristics of high morbidity, high recurrence rate and wide epidemic range. Infection is the source of many diseases, if genital tract infection can not be diagnosed and treated correctly in time, the risk of AIDS and cervical cancer is increased, and complications such as infertility, ectopic pregnancy, abortion, dead fetus, dead birth, premature birth, congenital infection, neonatal infection, chronic abdominal pain and the like are caused, which affects the health of two generations of people. The treatment of female genital tract infections is premised on accurate diagnosis, while accurate etiological diagnosis is premised on sample accuracy. Currently, the method for collecting a sample of the cul-de-sac secretions is as follows:

the first method comprises the following steps: a disposable sterile cotton swab is directly inserted into the rear dome to adhere the secretion, and then the cotton swab is placed into a test tube to be tested. In the sampling mode, the collected sample is easily polluted by the secretion of the inner wall of the vagina and the microorganisms of the vulva in the process of inserting and taking out the cotton swab, so that the detection accuracy is influenced.

The second method comprises the following steps: after the vagina is opened by a nurse or a clinician using the vaginal dilator, the secretion is collected by inserting a disposable sterile cotton swab into the posterior fornix, and the secretion swab is taken out after the collection is finished. The use of the vaginal dilator can avoid the contamination of the cotton swab by the secretion of the vaginal inner wall and the vulva microorganism in the sampling process, and ensure the accuracy of the sample.
