Description

Biological sample sampler

Technical Field

The utility model relates to a body cavity sampling equipment technical field especially relates to a biological sample sampler.

Background

The incidence of cervical cancer ranks fourth in female malignancies worldwide and is one of the malignant diseases that severely compromise female health. While HPV is the main cause of cervical cancer, the detection of DNA thereof is the main primary screening scheme for screening cervical cancer. HPV DNA detection needs to collect cervical exfoliated cells firstly, traditional cervical exfoliated cell collection needs medical personnel to use a vaginal speculum to dilate a vagina firstly, then use a sampling tool to wipe the surface of the cervix so as to collect cervical cells, and finally detection is carried out. The sampling mode is limited by places and needs to be carried out in a medical place; the privacy protection is not facilitated, and the sampling is required to be carried out by medical personnel; the operation is complex, and an auxiliary tool outside the sampling tool is needed; is easy to cause psychological and physiological discomfort of patients, especially fear, vaginal pain and bleeding;

in view of this, the 'HPV self-sampling detection technology' is proposed worldwide, namely, women can use a special cervical self-sampling device to sample at home according to an operation instruction, and then mail the sample back to a detection unit for detection, so that the result can be inquired on line, and the detection is convenient and fast. The HPV self-sampling technology can reduce the resistance emotion of women to gynecological examination, reduce discomfort caused by cervical examination and improve the coverage rate of cervical cancer screening. However, the HPV self-sampler on the market at present is few and has different sizes, and the unreasonable design of the sampler not only can cause the physiological discomfort of a user, but also can influence the sampling effect, thereby influencing the sample quality and finally influencing the detection result; the biological sample sampler of cervix uteri of using in the existing market basically all directly stretches into the vagina and takes a sample, structural many adoption cut straightly from rotating, and during practical application, the user is usually the operation in the closed environment, can't or few professional at the on-the-spot instruction, the speed that the sampling head stretched into the vagina on the one hand when stretching into the vagina with the sampler is wayward, it also rocks to shift easily to stretch into in-process sampling head, the cervical wall is bruised extremely easily, on the other hand the user can't accurately judge whether the sampling head reaches the sample position, if stretch into the distance of vagina not enough, influence sample validity, if stretch into the distance overlength of vagina then cause the injury to the cervix uteri easily.
