Self-service biological sample sampler

Abstract

The invention discloses a self-service biological sample sampler which comprises a sleeve and a push rod, the push rod is slidably arranged in the sleeve, one end of the push rod is provided with a sampling head, the sleeve comprises an extending pipe and a handheld pipe, the extending pipe is in threaded connection with the handheld pipe, and the push rod is provided with a first limiting part and a second limiting part. The extending pipe is provided with a limiting part matched with the first limiting part and the second limiting part, and when the limiting part abuts against the first limiting part, the sampling head is completely contained in the extending pipe; when the limiting part is propped against the second limiting part, the sampling head is exposed out of the extending pipe; the first limiting part is arranged, so that the sampling head can be completely accommodated in the sleeve and cannot automatically stretch out and fall off when the sampler is not used, and the second limiting part is arranged, so that the position and the stretching stroke of the sampling head can be fixed when the sampler is used; the stretching-in pipe is in threaded connection with the handheld pipe, the maximum stretching-out stroke of the sampling head is adjusted by adjusting the threaded stroke of the stretching-in pipe and the handheld pipe, and the applicability of the sampler is improved.

Description

technical field [0001] The invention relates to the technical field of body cavity sampling equipment, in particular to a self-service biological sample sampler. Background technique [0002] The incidence of cervical cancer ranks fourth among female malignant tumors in the world, and it is one of the malignant diseases that seriously endanger women's health. As the main cause of cervical cancer, HPV DNA detection is the main screening program for cervical cancer screening. The detection of HPV DNA requires the collection of cervical exfoliated cells first. The traditional collection of cervical exfoliated cells requires medical staff to use a speculum to dilate the vagina, and then use a sampling tool to wipe the surface of the cervix to collect cervical cells, and finally perform detection. This sampling method is limited by the location and needs to be carried out in a medical place; it is not conducive to privacy protection and needs to be sampled by medical personnel; ...

Problems solved by technology

However, there are few HPV self-samplers on the market and their sizes are different. The unreasonable design of the sampler will not only cause physiological discomfort for consumers and users, but also affect the sampling effect, thereby affecting the quality of the sample, and ultimately affecting the test results. The cervical biological sample samplers used are basically directly inserted into the reproductive tract for sampling, and the structure mostly adopts the in-line spin type, but in actual application, the user usually operates in a closed environment, and it is impossible or rarely Professionals guide on site. Users cannot accurately judge whether the sampling head has reached the sampling position. If the distance inserted into the reproductive tract is not enough, it will not be able to sample correctly and affect the validity of the sample. If the distance inserted into the reproductive tract is too long, it will easily cause damage to the cervix. harm
