An<unk>  (bottom) with a slide holding bottle The<unk>  is a device used to collect Pap smear. It is a wooden<unk>  with U shaped openings on one side and a flat surface on another. The broad end is for vaginal sample collection and the narrow end is for cervical sample collection. It is rotated 360 degrees in the vagina to obtain the cells to be sent for Pap smear examination. Recent studies have shown that long-tipped<unk> s (Aylesbury device) or a cytobrush along with an extended-tip<unk>  are better than<unk>  in collecting endocervical cells. However,<unk>  continues to be used for cervical sample collection in lower-income countries.<unk>  is introduced into the cervix after visualizing the os using a speculum. The cytology specimens are obtained by rotating the<unk>  firmly over the ectocervix and quickly transferring the cells to a slide or jar. The<unk>  was invented by James Ernest<unk>  and Georgios Papanikolaou.<unk>  was granted a patent for it in 1949 and donated the profits from sales of the<unk>  to the American Cancer Society.
