A kind of cervicovaginal tissue cell sample collection device for hpv detection experiment

Abstract

The invention discloses a cervicovaginal tissue cell sample collection device for HPV detection experiments, which belongs to the technical field of medical devices. It mainly includes vaginal expansion element, collection element, and power supply device. The collection element includes a limit fixing frame, collection adjustment rod, and collection head; the patient's vagina is expanded through the vaginal expansion element, which is convenient for the collection adjustment rod to enter for tissue cell collection, so that the camera The patient's cervix and vaginal wall can be photographed more clearly; the contact between the device and the patient's vaginal opening can be limited by the collection adjustment rod, so as to avoid the patient's injury caused by the insertion of the dilation air bag and the support buckle plate too deep; the replaceable The soft brush layer samples the tissue cells inside the patient's cervix and vagina to avoid cross-infection; through the micro camera on the collection head to take pictures, it is convenient for patients to understand the condition of their cervix and vagina, to detect diseases in time, and to treat them as soon as possible; the present invention The structure is simple, safe and efficient, and easy to operate, and is suitable for mass promotion.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for collecting cervicovaginal tissue cell samples for HPV detection experiments. Background technique [0002] HPV is a kind of papillomavacuolating virus A belonging to Papovaviridae. It is a spherical DNA virus that can cause squamous epithelial proliferation of human skin and mucous membranes, manifested as common warts, genital warts and other symptoms. With the rapid increase in the incidence of genital warts in sexually transmitted diseases and the increase in cervical cancer and anal cancer, HPV infection has attracted more and more attention. [0003] HPV detection is a means to deal with human papillomavirus. It is clinically proven that the virus is a DNA virus. Humans are the only host of HPV. It will cause disease. At present, scientists have proved that the HPV virus transmitted through sexual life is the main cause of cervical cancer. ...

Problems solved by technology

[0004] When the existing cervicovaginal tissue cell collection device is inserted into the patient's vagina, most of the duckbill tablets are used when dilating the patient's vagina, which is easy to cause damage to the inner wall of the patient's vagina; the depth of the device's entry cannot be controlled, and it is easy to cause harm to the patient; Clearly photograph the inner wall of the cervix and vagina of the patient, so that the patient cannot detect the condition in time and delay the best time for treatment
