Technical Field
The invention relates to the technical field of medical instruments, in particular to a vaginal secretion sampling device for gynecological clinical treatment.
Background
Vaginal secretion is formed by mixing vaginal mucosa exudate, cervical canal and endometrial gland secretion, and the formation of the vaginal secretion is related to the action of estrogen. When the ovary is about to ovulate in the middle period of menstruation, the cervix gland is exuberant in secretion, generally transparent and slightly sticky, and egg white is like. Before and after menstruation, vaginal mucosa exudate is increased due to pelvic congestion.
In gynecological examinations, hospitals generally take a swab from a test tube or bottle or other item and then remove the swab from the toilet. The female vaginal secretions are often removed with a cotton swab and placed in an open plastic bottle or tube and then transported to a laboratory for testing.
