Description

Vagina sampling swab

Technical Field

The utility model belongs to the technical field of detect the sample, especially, relate to a vagina sample swab.

Background

Rape (rape) refers to the act of forcibly intercourse against the will of women through violence, duress or other means. The suspect sperm is detected in the vagina of the victim, and the suspect can be determined to conduct rape behavior and have ejaculated. In sexual criminal cases, therefore, it is necessary to routinely extract a vaginal swab from a victim in order to work on semen (plaque). After sexual intercourse, only a few sperm enter the cervix, the rest remaining in the vagina. And it is generally considered that sperm cannot move 3 hours after sexual intercourse, and the time limit of detection in the vagina of a living body is 1.5-2 days. Therefore, the victims should report to the public security organization in time after sexual assault and pick up the vaginal swabs by the technicians involved. Forensic identification of semen (plaques) may provide clues for judging the nature of the case, delineating the scope of investigation, and identifying or excluding criminal suspects. For suspicious seminal stains inside and outside the vagina of a victim, gauze blocks or cotton swabs are mainly adopted for extraction at the present stage, the part from outside to inside to the fornix postnata in the vagina is divided into three sections, namely the outer end, the middle part and the fornix postnata, and the seminal stains are extracted by applying gauze to suck or wiping the seminal stains by the cotton swabs. Because semen has a certain adhesiveness, satisfactory results are often obtained by extracting the specimen.

However, the fibers of the gauze pieces and the cotton swabs are prone to dropping, causing sample contamination and inconvenience to the subsequent DNA extraction process. Meanwhile, no matter the gauze piece or the cotton swab is sampled, no warning line is used as an indication mark, a sampling person cannot accurately master the sampling depth, the sampling person is easily polluted, the discomfort of the sampled person is easily deepened, and even a lot of unnecessary injuries and risks are caused. In addition, since a plurality of samples at different positions are collected and the samples have the same shape, the samples are easy to be confused.
