Technical Field
The utility model relates to a sample collection device, especially a vaginal microecological sample collector.
Background
Vaginitis is a common gynecological disease of women, and the incidence rate is about 40-50%. The common symptoms of vaginitis mainly comprise vaginal pruritus, pain, secretion increase and foul smell. These symptoms are often exacerbated after a couple's life, resulting in women experiencing a sense of fear about the couple's life. Therefore, it not only brings physiological pain to the patient himself, but also seriously affects the physical and mental health and family harmony of his partner. In addition, it increases the incidence of urinary tract infection, cervicitis, premature labor, pelvic inflammation and AIDS.
With the development of sequencing technology, vaginal micro-ecological disorders have been considered as one of the pathogenesis of vaginitis. The condition for determining whether the patient has vaginal dysbiosis is that a vaginal microecological specimen of the patient is collected and then defined by 16S rDNA high-throughput or whole genome sequencing technology. Therefore, the precondition for judging whether the patient has the micro-ecological disorder is to collect the specimen which really represents the vaginal micro-ecology.
At present, the method for clinically collecting the vaginal microecological specimen and the defects thereof are as follows:
the first method comprises the following steps: the aseptic cotton swab is soaked by normal saline, then the cotton swab is stretched into the middle part of the vagina to rotate, and then the cotton swab is taken out and placed in a normal saline test tube for storage. The method has the following defects: the cotton swab is contaminated with vaginal microorganisms, and therefore the collected specimen does not completely represent vaginal microecology.
The second method comprises the following steps: the vaginal dilator is used for extending into the vagina, then a sterile cotton swab is used for collecting the secretion of the cervical orifice, and the cotton swab is placed into a normal saline test tube for storage. The method has the following defects: specimens can only represent cervical microecology, but cannot represent vaginal microecology. However, there are studies that show that cervical microbiology is different from vaginal one. Therefore, the vaginal dilator sampling method is not suitable for detecting vaginal microecology of patients.
Therefore, in order to collect the specimen which really represents the vaginal microecology, a collecting instrument which can not only avoid the microbial contamination of the external vaginal orifice but also collect the mucus in the middle of the vagina needs to be developed.
